ASUS A7N8X DELUXE trouble

[zillion]

Hi all, I'm back up and running with my new rig. My Specs:

ASUS A7N8X DELUXE
AMD Barton 2500
Generic 32 Meg SIS video card (until I buy my AIW 9700 pro)
Corsair Twinxms PC3200 512MB (two 256 chips) unbuffered
WD caviar 120gig 8MB cache
HP Cd Writer 8100

Ok, so I bought the high end silver compound coolant grease for better cpu-heatsink cooling and contact.

I am running WinXP but am having a few issues. Under Device Manager, it says my cpu is an AMD Athlon(tm) XP running at 1.09 ghz. Um, by factory default, isn't the Barton 2500 supposed to be about 1.8 ghz?!?!?! I am not overclocking yet or anything (obviously) but at some point wanted to try it. SO the 1.09 is the first issue.

Secondly, I don't know how to know for certain if my memory is in dual channel mode (this feature is a big reason for choosing this mobo). Device manager says 512MB so I think I installed the TwinXMS chips correctly based on the manual's configuration.
However, also on startup, the built in "Vocal POST messages" (a feature of this board) blurts out "System failed memory test"... so, what is wrong?

Is there a way to speed up the startup process by disabling the search for RAID components? Is there a toggle in the bios? I may someday have RAID drives installed but for now there is no need for it to search every time I startup.

Finally, should I update my bios (I think I have the 2.0 version?!)
before doing any of these tweaks?

I bought the CPU, Mobo and Corsair all new from NEWEGG.com.
I hear they are great but never used them before. Is something possibly defective?

Thanks!! -Z

if you are running at 1.09ghz you probably need to set the front side bus to 166mhz in the BIOS. Instructions in the mobo manual.:)

Dual channel is automatic as long as the fsb and memory speed are the same(100% is the setting in bios).Instructions in the mobo manual.:)

You can not switch off the Promise SATA chip in the bios, it's switched off by a jumper next to it in the mobo. Instructions in the manual.:t

"However, also on startup, the built in "Vocal POST messages" (a feature of this board) blurts out "System failed memory test"... so, what is wrong?"

Mem is set to aggresive in timings. Set to SPD-NOT manual. IF still says failed then mem issue for sure. You did use recomended mem from manufacturer right. Asus has a mem compat sheet on site for this mobo. You also need ddr400 or 333 for barton to run properly in synch mode.

:t

[Ammok]

he's got 400mhz ram so should be fine, but your bios settings do not appear to be set properly. Honestly, go through the settings and optimise them for an optimal system, no overclocking or such yet, and you will be well pleased. Read the manual thoroughly.:t

[ComPooTer]

looks like he just plugged everything in and tried to play :D

gotta set everything in bios first bud

166x11@1826

yeah if u read the manual itll solve ure problems

Eh? 400mhz has nothing to do with timings of mem. Thats the clock freq. Timings are cas ras tas and etc. Set to spd and those WILL be set to what the mem manufacturer rated that mem at. ;) I can take 400mhz fsb mem and run it at 333mhz with fast timings and have it choke all over the place with errors and hang ups. Been there done that. Timings are tons harder on mem then fsb alone is. Try cas 1 if you dont believe me. Cas is harshest and least beneficial to mem today with these high mhz cas means less and less.! Less you drop it down and raise fsb which brings us back to square one anyhow. :t

[Ammok]

I was thinking fsb, but he did say he had pc3200 which is 400mhz, so that was what I meant, but your absolutely correct to mention the cas,ras, and spd as these will certainly have a bad effect on the system if they are not set right.:)

[zillion]

That memory test error was all based on Bios settings, thanks.
However, some new issues.

I have adjusted the CPU FSB from 100 to 166 and yes, my PC boots up and is now Running a Athlon 2500 at 1.83 ghz... but, then my modem won't connect to the web... how are the two related?!? I have a dial up V.92 Creative Labs Modem Blaster.
What can I do?

The FSB setting has one more option above 166 which is 200.
Can I try that or is that dangerous? Seemingly, the memory or "resulting frequency" is 200 when the cpu is set at 166 so where am I off base?

I would like to optimize speed on my PC but don't know the bios tweaks.. anyone with a similar system that could reccomend some changes like "aggressive modes" or QFan control settings?
Etc?

In general, the mobo manual is worthless when it comes to settings being modified. The descriptions require full understanding of the PC jargon which is brutal to newbies. I am fairly computer savvy but still, an example: I wondered what the GateA20 feature in "Advanced Bios" was and it states- "GATE A20 Option: This field sets the gate A20 rate. [Normal] [Fast]"
With most features, I'm like "great.. what the Frick is a Gate A20?!"

Not entirely true...Ammok.

Dual channel only works on the A7N8X Dlxe if you put the memory in slots 1 and 3...OR...2 and 3.
Some fine print there...

And...zillion, dual channel does not mean the memory you have installed will double in BIOS or windows...it just means the data going to and coming out of it has increased bandwidth as the result of dual channel (honestly, not a HUGE difference...)

An Asus Manual will not specifically tell you how to Overclock your system.
BUT...there are a TON of posts and threads here that will!

It's not usually just as simple as raising the FSB and living happily ever after.

A couple of things involved...multiplier, FSB, CPU Voltage core, and...most importantly...cooling. I've built three of these systems.
Mine, I have a nice Vantec Aeroflow Heat Sync/Fan combo.
I have mine OC'd to 2200MHz, up from stock 1.833. The two others I've built, running at an even 2000, but on the stock HSF combo...and stock voltage.

Before I go re-write the bible...do some searching in this forum on the Barton 2500 and the Asus A7N8X deluxe. There is a ton of stuff here, great advice...and most helpful suggestions.

Good luck!!

[missiveusa]

Try this forum (http://www.nforcershq.com/forum/viewforum.php?f=13) for good advice on A7N8X. Read the stickies for info to supplement your manual.
I'm running PC 3200 with a 166 MHz XP 2600 at 100%, in other words, I am underclocking the 400 MHz RAM to 333 MHz with agressive timings (6-2-2-2). Whatever you do, try to run the system in "sync" mode, or 100% of external frequency.

[Ammok]

I do believe I did mention that he should read the manual, not that I intended to replicate the contents here in any case. Everything I have told him is in his manual, if he wants to bung the memory in slots one and two thats up to him. But he should read his manual and post back on what he does not understand. I'll persevere with people who are trying their best, but when you got a brand new mobo and perhaps just can't be bothered reading the instructions, don't blame me if I miss something out cos I didn't read the manual.:D

[dajogejr]

True enough...Am...

So, what you're trying to say, Is I just can't look at the pictures and figure it out??

:x

[Ammok]

LOL.:D

Rule one: bung it all together....



rule one hundred and fifty, think up a plausible explantion to the missus as to why your rummaging through the garbage looking for the instructions that were tosssed aside as soon the box was opened.

Been there, done that, got the the T-shirt,LOL. (even now I'm so tempted not to read instructions, must be a man thing, a challenge too irressistible to ingore):t

[zillion]

I did read the manual in fact cover to cover as it is of great interest to me, however, still, certain terms are beyond me (as I made reference to in my last post.

I am pretty good with computers and building them, but I never tweaked memory, cpu, or stuff like that.

I do have the memory chips in the proper slots and they work in dual channel mode and I can get it to say it in the opening black screen AND the voice POST thingy doesn't say fail anymore... so that is fine.

I just want to know what tweaks are safe and what could hurt something as I don't have the cash or time to replace a dead part.
I've experimented with VARIOUS settings and tweaks however I still can't get one thing working without sacrificing another. IF I increase the CPU FSB from 100 to 133, all seems to work and I can connect to the web. Still, now my cpu is recognized as an Athlon 1900 at like 1.4 ghz. If I increase it anymore to 166, then seemingly, all is fine in windows, and it is said to be an Athlon 2500 at 1.84 ghz, however, then in Juno (my ISP) I can't connect to the web. My modem just stalls. Based on my specs, can someone suggest a memory/cpu etc. settings to try out? Should I try FSB 200 on the CPU? I think that is for later AMD's like the 3200 so I am scared of hurting something. I have tried even setting stuff to "Agressive" but that didn't help either.
Should I enable the Q-fan to give more fan speed/cooling? Perfect example in that I know that the Fan Speed Ratio and Speed Up/Down Response Time are aspects of Q-fan control, but I don't know how I should know what to set them at.

Also,

I can't install the PC Probe software which could make tweaks easier or at least monitoring performance. Both the software CD and the installer I downloaded from ASUS's website do not download. I instead get a window that pops up saying "16 bit Windows Subsystem" with the description:
"C:\WINDOWS\SYSTEM32\CONFIG.NT. The system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose 'Close' to terminate the application." Both CLOSE and IGNORE don't do anything but close out.

Thanks guys for any help!!!

[dajogejr]

That's an odd one. CPU speed, especially at stock rating, should have nothing to do with connecting to the web...

I know the mobo comes with a drivers CD, but chances are they are already outdated.

First, have you installed the latest 4 in 1 drivers from Asus?
Second, do you have the current video drivers from the manufacturer's site?
And...what version board is that? 2.0 I imagine. If you're not sure, look between the 2nd and 3rd PCI slots, it'll say PCB Ver. XXXX...where xxxx is 1. something or 2.0.

Get the correct BIOS flash update for the board.

Here's what I'd try...and it should work fine.

Multiplier: 10
FSB: 200
That will give you an even 2000 MHz CPU rating.
Run the memory at SPD, which will result in 200MHz.

Timings..I would start out at 7, 3, 3, 3. You can relax them from there, but that is a very safe point.

See where that gets you.

BIOS first. 4 in 1 drivers next. Video next. Then, set it correctly in BIOS as stated above. Keep an eye on your CPU temps, depending on your local...I would say about 45C or so should be about right for a stock HSF setup, give or take a few degrees.

Let us know how that works...

Oh...and do you have the correct drivers for your modem, and the lastest version of Juno for your OS?

[zillion]

Ok dajogejr, I tried your settings and now I am running at 2 ghz exactly when I right click on My Computer and dual channel TwinXMS Corsair PC3200 512 megs. In the opening black screen it said dual channel and result 200 FSB. I thought my Barton 2500 only went up to 166.

So, the connect to the web issue comes down to Creative Labs. I uninstalled my modem and restarted and Windows' generic driver works fine. Same 45.2 kbs connection speed as before too. Something I guess to do with the CL drivers.

I am 99.9% sure my mobo is the 2.0 version as I just bought it too. I will download the latest 4 in 1 drivers and bios. You were right in that my cpu temp is exactly 45 degrees C.

So, the memory latency settings... should I adjust the 7,3,3,3 at all now? What to? Should I try aggressive mode on anything?

[dajogejr]

He he...good for you, first of all.

The STOCK FACTORY ratings for your chip is 333FSB. Which, in BIOS, is 166. But...this chip, as you will find in a bunch of posts on this forum, is a fantastic little overclocker.

You won't be able to clock that chip quite as high as an EPoX board, but...with only decent aftermarket air cooling, maybe a 30 dollar HSF, you can use it at XP3200+ speeds, (2200MHz) all day long without a wimper from the chip.

To be honest, I have mine set at 7, 3, 3, and 2.5.
With all I do on mine, surf, email, Office apps and gaming...it does all I need and begs for more.

You can lower the settings 1 at a time...but 6-2-2-2.5 is probably about all you're gonna get. Probably won't notice much of a difference, if at all, from where you're at now. I wouldn't expect a turbo charge from these minor settings...more or less a "tiny" bump in a benchmark.

Once out of 9 or 10 times, I'll get the post voice message system memory check failed, computer now booting from operating system. Not sure why, and I don't care. I've had my memory settings like that for almost 3 months, and the OS boots fine and runs fine...all day long. Although, I updated my BIOS to the latest and greatest 3 days ago...haven't heard the voice:) I have two 512MB of PC3200 Crucial, which I know are 100% fine.

I have my BIOS set to aggressive if menu wasn't available. (Menu allows you to adjust certain items by 1MHz intervals...very nice to fine tune.) But, you'll get to a point...where it's like, ok...it's been running fine at XXXX MHz for a month...do I really need an extra 10 or 20 and risk instability...?

Let us know how it turns out...I think you'll be more than happy!

[zillion]

Ok I got my memory at 6,3,2, 2.5 and everything seems great. At 6,2,2,2.5 it won't boot so is the above still "safe" or should I give it a bit of breathing room?

Now if only I could get Asus's Probe software to want to install. Any ideas based on that error message I wrote?

Finally, my CPU temp is at around 52C. Is that good? What is the danger zone? And The Qfan settings... I set it to enabled, but the fan speed on Full but what should the ratio be.. 4/8 1/2 etc.
Is the bigger number better or worse?

Wow, after that I may be ready to research overclocking. :)

[ComPooTer]

52 idle or 52 load.......................52 load is fine if its 52 idle, 52 idle is just bad

[dajogejr]

I would set 'em to 6, 3, 3 and 2.5. And live happily ever after...

How many case fans do you have? At least two, I hope.
One in the front near the bottom, sucking in cool air...one at the top in the back, under the power supply sucking warm air out of the case...

I set my QFan to full speed. My CPU is the quietest fan I have in the case...so, let it run full speed. The QFan is really for noisier fans to help quiet the sound a bit....

52 is a little warm for idle...so, please specify. Also, where are you getting this number from, Asus probe or the mobo??

[zillion]

The numbers and temps I gave were what was listed in my bios editing window(s) when I hit "delete" on start up.

I just changed to 6,3,3,2.5 (from 6,3,2,2.5) and currently my temps are:

Mobo: 32C/89F
CPU: 51 (and 52)C/125F

I have Qfan enabled and set to Full speed.
My Speed Up/Down Response Time I just set to 1sec/2sec though I don't know what this feature is and each ratio option seems to do nothing.

So, to answer the question if the temps are when idle, I don't know for sure, but it would seem to me it must be because it is listed in the bios screen (and how much more idle can a system be if not off, right?). So 52C is bad? What will bring it down?
Thanks! -Z

[dajogejr]

That's a little warm...
With fan set at full speed, second response time doesn't mean anything...don't worry about it.

Oh, and download either Aida32 or Asus Probe, and check your temps in there, too...


Need you to specify your case/fan setup...

[zillion]

As far as Asus PC Probe, I did download it but I can't install it. The installer off my CD and the newer download one both give me that error I typed earlier in this post. Any ideas on that problem?

The fan setup I have is pretty good. I have my Barton CPU heatsink fan that came with it, in addition to two Antec fans that came with my big *** Antec case. There is much breathing room in the case, and the top fan I have blowing in towards the cpu and the lower one spitting warm air out. I could reverse those two if you think it is better.

Thanks again!!! I look forward to your reply.

[dajogejr]

I would recommend pointing any fans OTHER than the one in back by the PSU inward, sucking outside air in.

I have 3 fans sucking in, one sucking out...and I've gotten my best temps that way.

Try searching Micro$ofts site with that error...see if there is a patch or fix to affect that.

Just found this:

http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q142271&

[paradox]

my findings helpful or not

my 2500 barton IS NOT stable at any multiplier setting at 200Mhz or above (199 and below rock solid, currently 11.5x199) temp does seem slightly high, you are at idle. Temp at load would be after gaming or benchmarking (mine 55-57Celsius at load with extra cooling)

asus probe software shows about 15 Celsius lower than in bios, not worth the trouble your having right now any way

the memory timings in dual channel actually benefit when set 11-x-x-x (the last 3 numbers tweak low as you can go)
other posts will back this up just don't have any bookmarks for you, also with my system stable and no timing changes i increased my mem voltage and benchmarking increased as well anomoly? maybe

Wil's Specs
Barton 2500 (11.5*199Mhz 1.7V)
Asus A7N8X Deluxe 2.0
2x512 Mb (in dual channel, but not a kit) OCZ 3200 premier (198Mhz 11-3-2-2T 2.8V, stable at 2.6V though)
mem and cpu don't sync at 199 Mhz

[dajogejr]

Paradox:
Curious...11 on the memory? Hmm...may have to change mine to see!

Do you think that may be why your FSB won't run at 200?

I'm very surprised, with a Rev. 2.0 board especially, that it won't run stable at 200...I've read good and bad, mostly here...about OCZ. From what I've read, newer chips seem to be fine. It was older chips that had problems...

Funny...Aida32 and Probe both report a few degrees higher than my BIOS...

Mine will run 100% stable at 1.75. Tried stock voltage and everything up to 1.750...and that has never given me problems at all..

I'm getting a True Control 550W PSU in the next month or so, gonna see if I can back off the VCore a tad with that installed. I think my 350W Antec True Blue is holding me up from a lower VCore stability...we'll see.

[paradox]

well tried alot of timings (tight, OCZ recommenend, extremely loose, etc) all when cpu was 12*200 @1.85V (thought was good) got the memory error every so often from Asus board, random game crashes the odd window reboot. Came down to CPU. still ramping up to higher mulitpiliers but not so quick this time. I've also heard there's an "old & new" barton, early barton cores supposedly can't overclock very well

the sync in bios 1005 is weird (mem at 100%) i up the FSB mem follows except at a few odd settings where the mem instead of 1Mhz increments needs 2mhz. I see 1006 is out maybe that'll fix the problem

tried 2 versions of the probe both were the same reading also the fan readouts are opposite to what is stamped on my motherboard PWR=Chassis and viceversa

Enermax 350

still cant find the other forums about timings sorry. but with memtest x86 ver3 it shows a decrease in bandwidth when not at 11 and with 3dmark2000, pcmark2002,hot cpu tester3 lower scores on average only a couple points though.

[dajogejr]

I don't think I have an Old barton...but not new. Had if for about 4 months...
Love it. For about 90 bucks from New Egg, I'm thinking of getting another...just to have as a spare. For that much, why not??

I would say one out of 10 or 11 boots, I'll get the system failed memory test voice error. Everything runs just fine, though...and, I've run memtest86 for hours and hours, about 3 times. I'm convinced it's a minor bug...and I'm not going to concern myself with it...

Gonna try the 11 setting now...Thanx parodox!

[zillion]

Ok, I moved to a different part of town and just got a phone line installed so I am back up and running. I read the suggestions in memory timings about going up to 11 (gotta love Spinal Tap.. hee hee). The 11 seems to have enabled me to lower my last two numbers to 2 and I found I can load windows w/o error at 11,3,2,2.

I then played with moving my CPU multiplier up in .5 increments and now that two is at 11. I tried 11.5 to get it at 3300 mhz but XP wouldn't boot. So now I am at 11 and Windows thinks my Barton 2500 is a 3200 and I am clocked at 2.2 ghz on stock cooling.

So, my question is... should I sacrifice some speed for cooler temps? When I push delete at startup to enter bios... what range should my cpu be in? It is at 53 C right now. I may switch directions of fans to see if that helps too. Otherwise, what settings should I alter to bring it down? Thanks! -Z

[dajogejr]

First things first. I assume you are getting these temps from BIOS.
Download and install Aida32, and see what temps you get from that.

I get a few degrees higher from Aida and Asus PC Probe than in BIOS...so I go by that.

53C under full load isn't bad...idle is a bit warm.

Mine runs at 38 to 40C idle, 43 to 45 loaded. Depends on how warm it is in the room.

You really have a few options, but they depend on the following.

1. More case fans, or point the ones you have in another direction...if you have the spaces...

2. What is your V Core setting? (Voltage setting for CPU) Stock for that chip is 1.65, but I have to bump mine to 1.75 for stability at 11X200. A little more VCore will bump the temps but will stabilize it if needed. Only use as much as you need to keep it stable.

3. Depending on your answer for #1...for less than 30 US$, you can get a good aftermarket HSF for yours...to help. The factory HSF is actually not too bad, but at 3200XP levels for that chip...a little better HSF is probably in order.

BTW...in my case. I've tried about every memory settings in BIOS...but I've gone back to 6-3-3-2.5 and have no problems...

I can't get mine stable above 2200...it'll boot and run, just not stable. 2200 is just fine for me...

[zillion]

wow, quick reply!! Thanks dajogejr!

Adia32 is cool stuff! Also I switched fan direction so top spits hot out and bottom invites cool in.

Ok, my Vcore settings is stock 1.65 I/O is 1.6.. here is what the software says:

So far everything is stable... just a bit warm? Should I lower something to cool off for now? Thanks!

[dajogejr]

Well...what are the temps in AIDA32?

And...if it's stable with stock VCore, good for you. Can't ask for more than that...

So, you have a few options now that it's sorted out.

1. More and/or more powerful case fans, usually this results in more noise...
2. A better aftermarket HSF, or
3. :( Less Overclock.

Tell you what...run it at stock speeds for a bit. 166X11 I believe.

See if the temps drop a bit more. If they only drop a degree or two, I'd advise options one OR 2. If it drop significantly, 4 degrees or more, then you'll probably need one AND two.

How many case fans do you currently have?

Actually...rereading one of your earlier posts...try this.
Sound like you have space for at least 3 fans. One in front in the bottom (which should be sucking cooler air into the case.) One on the top of the case, (which, in my experience...should be sucking cool air into the case, but you may find different...) and the third...the one on the back, underneath your power supply. This should be pointed outwards, or...should be sucking the warm air in the case blowing it outside.

Does this sound like your setup?

[zillion]

As far as my fans go, I have two rear ones... The upper one spitting warm out and the lower one sucking cool in. Plus I have my heatsink fan of course. I do have an extra fan in my older DELL and that system is not being used... maybe I should throw that one in the front of the case as you say sucking cool air in.

Ok, I realized that my Aida32 report showed the wattage but not the temps... so sorry about that. I just searched through everything in the menus though and can't seem to find an option for me to find my temps. :(

I did check what my temps were in my "power on, delete" bios and they seem to have gone down to 48-49 degrees C so THAT's good.

Any ideas in Aida32? Thanks! -Z

[dajogejr]

Yes sir.
You need both in the back, under the power supply, sucking air out of the case.

You need one in front, sucking colder air into the case.

If you have other fans, side or top, have them sucking cold air into the case as well.

Sounds like the two fans in the back may be fighting eachother...
As far as Aida32.

Open it up, go to comptuter. There should be an icon, sensor. Click on that...and it will tell you the values in the right window pane...

[zillion]

Thanks!!!!!!!!!
Hey, even with "fighting" fans, my Aida32 temps seem fine! Look:

Sensor Properties
Sensor Type Asus ASB100 Bach, Winbond W83L785TS-S
Sensor Access SMBus 2Dh, SMBus 2Eh
Motherboard Name Asus A7N8X

Temperatures
Motherboard 31 °C (88 °F)
CPU 45 °C (113 °F)
CPU Diode 56 °C (133 °F)

Cooling Fans
CPU 2960 RPM

Voltage Values
CPU Core 1.71 V
CPU Aux 1.71 V
+3.3 V 3.41 V
+5 V 5.00 V
+12 V 12.48 V
-12 V -12.40 V
-5 V -4.70 V


And... these are supposed to be "liberal" estimates in comparison to the "power on, delete" bios menu, correct? So, now I'm pretty cool, right? (No pun intended.. hee hee)



:cool: :cool:

[dajogejr]

Well...to be on the safer side, I go by the higher temp.

Mine is the opposite of most. BIOS temp is cooler than AIDA or Asus Probe...but even the hottest I see is well acceptable.

Keep an eye on that temp...

My fan on my HSF runs at 5000 + RPMs..but it's the TMD type, Vantec Aeroflow, and it's very, very quiet.

Goog thing is...our board has COP (CPU Overheating Protection)

So...in theory, it'll shut down if it gets too warm. Get some case fans...run it...but if it starts shutting down under heavy loads...you may want to look into a better HSF, upping the Vcore a hair...or a combination of both.
It is truly a trial and error deal, and you'll gain a ton of knowledge from it.

Good luck!!
