XP 2600-M @ 2.65GHz

[dragflameson]

http://pages.cthome.net/dragfameson/Computer/2.65GHz_2.JPG k, DOOM 3 Time!

Edit:
p.s. This *will* be close to 3.0GHz by the time I'm done with it!... to be continued

[The Lodge]

Very nice drag. I haven't even started to tweak mine yet, haven't had the time.

[dragflameson]

Thanks, and yes, it takes lots of time, never realized lol... you got the "goods", right? I'm usin it now :)

I had to turn everything back down for a little :( My freakin PSU is on its way out now, figures :rolleyes:

2.65GHz is sooooooooooo fast though! I need a new PSU ASAP!!!

I couldnt get it any higher without it being stable, I was turning the Vcore up and my system was just totally shutting off - power button wasnt even working to turn it back on until I turned the PSU off for a sec and back on again. You think its my PSU holding me back now? I do.

[The Lodge]

Yeah I got the “goods”. Like I said, very few know. It’s a tedious process isn’t it? People think it takes about an hour to find your oc. What they don’t realize is the time it takes to test the stability. Up a little and test, up a little more and test. It’s a vicious cycle.

What kind off ps do you have? Also what ram are you using?

[dragflameson]

Oh yeah lol... forgot there are no sig's here!

My system is:

Abit NF7-S nForce2 Chipset (Model: NF7-S V2)
AMD Mobile Athlon XP2600 (IQYHA: 0401 XPMW)
GeForce FX 5700 Ultra GPU
OCZ EB Series Platinum Edition 1GB (512MBx2) PC-3500
ThermalRight SLK-900A HSF w/ VANTEC Tornado
Thermaltake Silent PurePower 420W PSU
Air Cooling Setup - Intake 3x80mm Exhaust 4x80mm ANTEC 80mm blue LED fans, 34CFM & 30 dB each.

My PSU is around 2 years old now *thinking*

[megaspazz]

decent system drag. i recently bought a 2700+ but it's a Tbred core, not a Barton.
still better than my old 1800+.

have barely started to oc this one...

[dragflameson]

Cool :cool:

Before this one I had the Duron 1.8 when I really started reading about o/c'ing. So I wanted to o/c it, but it was locked and my motherboard was old and crappy, so I was only able to get it up to 1.97GHz adjusting only the system bus - then I was addicted! so I bought the mobile, new mobo, new ram and HSF :D

Now I got a $100.00 chip and speeds of a $400.00+ chip (as soon as I get a new PSU - it seems like its getting worse and worse now, the OC killed it I think! lol)

[megaspazz]

yeah- deadly ram in your sys btw.

i'm needing another 256M of pc3200 now-
bf:vietnam isn't playing so well on only
256M. gotta play with low detail- booooo.
:rolleyes:

My Doom 3 plays so much nicer now with more memory, it wasnt bad before with my old 768MB of PC2100, but the new memory was def. a NOTICABLE change :) I still got it running at 240MHz, but I cant increase the multi too much, because then I need to raise the Vcore with it, and then I think my PSU cant take it or somethin... so I'll have to get a new PSU and let you guys know if that was it. I'm going on vacation now, tty all later in a week :r

[fishybawb]

That's a nice OC :cool: I still haven't got around to playing with my 2500+ Mobile properly yet, but I installed it in a new SFF system over the weekend, booted it up at 200x11 with 1.60v and it's rock solid. I'm hopeful for continuing good results. Gotta love these Mobiles :)

[Happy Joe]

Excellent OC!!! Congrats!!!
Mobiles are great... luved mine to death, worst is I never got to play doom on it. :(
Enjoy!

[Someone Stupid]

Your PSU doesn't look to be the issue being 420 watts though it is acting like it is which is odd. You don't have all your IDE/SATA channels tied up with drives or running a ton of lights? I can't see it failing from just a CPU overclock at that wattage. TT actually supplies fairly solid PSUs from what I've read in many reviews, though I've stuck with Antec for the most part. I've ran higher voltages on far worse a PSU before. Still that looks to be the part I'd pull if it continues.

I think you've hit the processors ceiling, or are damned close to it. Watercooling might net you another multiplier, but I don't see you going much further. How is your nb cooling? Still stock? Running that high an FSB also may be the case with stock cooling or a low vdd.

Great OC btw.

[dragflameson]

Thanks :)

I just got back from vacation. I left Sandra burn in going the whole time I was gone, made over 12,000 pass's lol. Max temp was only 35C.

I think it may be the PSU, this thing has been really getting used good for the last 2 years, I think I'll start looking for a new one soon and see what happens.

Nb cooling is still stock on the Abit, nice little fan ;) I could always replace that, but its stable as hell at 240MHz so I doubt that temp is an issue. I let it run all week at a lower multi and vcore, but at the same 240MHz and it didnt crash. Once I get the Vcore up to about 1.75 ~ 1.85 it just turns off and the power button wont work to turn it back on again until after I turn the PSU off and back on again (and I need to wait for the motherboard light to go out before I turn the PSU back on again before the power button will work agian).

[Bigjakkstaffa]

Thats impressive, given that my standard XP2400+ needs 1.825v to be stable at 2.35Ghz.

Given that im not upgrading my machine for three years at least now (at which point i'll be building a new machine - if im still interested in the things), im going after a Mobile XP in order to squeeze the maximum performance out of my current architecture, if i can get a similar speed out of it, i'll be mucho happy, especially if i can do it at 1.7xv Vcore (1.85v belches out a ridiculous amount of heat)

(PS: Mobile CPU's dont have this 12.5x multiplier limit i keep hearing of do they?)

[dragflameson]

I do see a lot at 12.5x though, never seen any over it... but then again, if you where over 12.5, lets say even at 13x you would be at 3GHz with only 230FSB. Most people are hitting 230-250MHz on these Abit's.

[Someone Stupid]

IIRC they do have the same limit. Though I may very well be wrong on that.

What are your voltages, that would be the first thing I'd look at before I'd up and decide to replace it.

[dragflameson]

Jakk, I just tried 13x - Couldnt boot, guess its true.

[dragflameson]

Someone Stupid, here is where I currently stand stable.

http://pages.cthome.net/dragfameson/Computer/2.57GHz_stable.JPG

Now again, that is stable. I cant get it any higher without some kind of problem though. I get the FSB up more and leave the multi at 11 it wont boot... I leave the FSB where it is and increase the multi the thing shuts off.

All I can think of is that when I raise the multi if I do not raise the Vcore with it then it wont boot, because it needs more voltage. So then I raise the voltage up to about 1.8V and it will then begin to boot, and get maybe to the Windows screen, then thats about when it will just shut off - which is when I cannot get it to turn back on until I turn the PSU totally off, wait for the moherboard light to go out, and then turn the PSU back on - then I can turn the PC back on to lower the mutli/vcore.

It's so annoying!!! This other guy with the almost the same specs is running 2.7GHz stable - 12 multi and like 220 something MHz FSB.

[Bigjakkstaffa]

The 12.5x multi lock appears to be a motherboard generated thing (sumink about using 4-Bits instead of 5-Bits for Multiplier generation). TO get aroudn it some reccomend a "wire" tricked in the CPU Socket, however crossing one of the bridges on the CPU seems an altogether safer and better option:

(see half-way down)

--Jakk:t

[Someone Stupid]

If it gets to windows at 1.8, try 1.825 or 1.85. That should get you over the last hump, at least to get into windows. You may need 1.85 for complete stability as there is a point where you just need a ton of voltage for the last little bits you are going to gain.

Not all chips are the same unfortunately. It takes me 2.15 volts to hit 2.4 stable.

I meant what are your voltages as read in the bios at your highest stable?
12v, 7v, Vcore, Vdimm, etc.

That will tell you fairly easily if it is the PSU or not and I'm really not thinking that it is. Two years for a PSU, it should still work if it is of decent quality easily, and TT makes above average PSU's, though not the best, they are better than their cooling solutions. :)

[Bigjakkstaffa]

Dragflameson, what sort of AMD PR rating is Sandra reporting for you at 2.5/2.6Ghz?

--Jakk:t

[dragflameson]

I figured out what was up. My PSU is not going bad :p

Had to do with my specific board/CPU combo. Turned out to be the Thermal Diode. Because the mobile CPU's are thinner than "desktop CPU's" the diode was not making proper contact with the CPU.

I had to take the CPU out and bend the blue diode vertically... bent it pretty high and had to force the CPU down while I snapped it in lmao, but hey... it WORKED! :D

[Happy Joe]

This is makin' my overclockin' bones itch for a new mobile and a decent MOBO!
I keep hoping that I can resist untill the DFI 64 bit nforce board becomes availiable...but yer makin' it difficult!
Enjoy!

[dragflameson]

Happy Joe, I gave in myself. I was waiting for that MSI Neo2 to come out, which was taking forever... I think it may have just came out a few days ago. But anyways I was going to get that board with a A64 3200, but then I started reading and found that I could get the same speeds for so much more less, I'll just wait another 1 and 1/2 years to upgrade to the newer sockets once PCI Express has been out longer, for now I'm good at 2.6GHz :D And I'm thinking about water cooling too, I always wanted to do that, so I probably will.. maybe I can hit 3GHz?

[Someone Stupid]

I hate to burst your bubble, but that isn't going to happen - you'll have to step up to more than just water. A 350 odd megahertz gain going to water isn't something I hear of from a previously aircooled system unless the cooling is absolutely horrible (stock).

Be happy with what you have. If it cost you 200-300 bucks to gain another couple hundred (let's just say) MHz, then wouldn't you just have been better off getting the A64. I never saw the idea of having high end WC gear yet running second tier parts per se. Yes the block can be used over several platforms to say the least with minimal cost, but if your making a long term outlay, you might as well make it a good one since you'd plan on keeping it for awhile longer than a single system easily. For your wallet's sake I'd just stick with it at 2.65. Any faster really isn't yielding you much at all for the cost in terms of performance as your a decent ways up on the curve, past what is cheaply and readily available for the most part.

[Happy Joe]

I hate to say it but I ageree with Someone Stupid as far as a practical system goes. If (like me) you are an O/C addict the priorites may change your definition of "practical". For me water cooling was a lot like marrage: it was good for a while (everyone should do it once) but I'm not sure I will do it again (I do get tempted though). If you build your own the cost is not that significant ($100 -150 for a pump and block and about $20 for a large new heater core (coppper 77 bonneville) then throw in another 30-$40 for some 120mm fans). If you are an avowed scrounger you can pick up a dehumidifier or air conditioner (for free) and make a water chiller (this might get you to 3.0 ghz), but again for normal use its not very "practical".
Enjoy!

Hey Drag, my XP2500-M came today. Did the wire trick (it's a fiddly bugger, took me nealry half an hour to get it set up :mad: ), at present im up to 2.34Ghz on 1.6v, thats almost the same as what my XP2400+ maxed out on.. at 1.85v. Im gonna have fun tonight :D

--Jakk:t Hell yeah, Good to hear :D

I got mine in peices right now lol. I'm waiting for my new modded Fortron PSU to come in this Friday and just took everything apart. I'm going to re-run everything to get better air flow and to make it look even better

"Wire trick" - you're talking about the L12 mod right?

Edit: Meaning this socket mod:

http://pages.cthome.net/dragfameson/Computer/L12_5.jpg

Here is a pic of mine:

[porsch1909]

im trying to get funding (from parents) to build a whole new rig but they will have nothing of it....they wont even let me spend my money on one!!! they keep saying that my old one is super good(which it is) they just dont get that i want to OC out of interest not for a faster PC. my first rig is a dell so the BIOS is locked, ill have to presuade my brother to let me at his.


so the basics of OC is increase multiplyer and VCORE and then you can increase FSB. just now i increase just FSB and i get the 2600 up to 2.06 GHz which is pretty good. you mobos chipset is far superior though.

nice OCing though man.

[Bigjakkstaffa]

The multiplier Wire Mod:

http://www.ocforums.com/attachment.php?attachmentid=28155&stc=1

http://mysite.verizon.net/vze24h2j/Mykex/socket.jpg

(depending upon the orientation of the socket)

The L12 wire mod is for boosting the default FSB to 200MHz as opposed to 133/166Mhz.

As for me, looks like im stuck at 14x Multi tops, though i can maybe get another 5Mhz out of the FSB taking me up to 2.4Ghz. had to adjust up to 1.7v but seems rock solid ATM

--Jakk:t

[dragflameson]

Oh okay, I didnt do that multi wire mod.

I did the L12 mod on the Abit that brought me from 133MHz to 166MHz ;)

Maybe I'll try that multi wire mod, though I'm not sure if I'll ever even bring it higher than 12.5x - we'll see ;)

1.7V isnt too bad, I talk to ppl who are running 2.0Vcore with these chips - I'm sure mine will be up there soon enough :)

Edit: For that multi wire mod, you just made a "U" shaped wire and stuck it in the socket like I did with the L12 Mod, correct?

[Bigjakkstaffa]

Yup.

Well, i've managed to get a post at 2.5Ghz, however it wants in excess of 1.85v to stay stable, and on my cooling, i aint giving it that!

It's a shame i havent got a 14.5x multiplier as that would put me nicely over the 2400Mhz mark, which im sure could be done at 1.75-1.775v.14x is too little, 15x way too much, oh well, can't complain, i've got my old overclock at a much lower temperature and power consumption, plus an extra 256k of L2, not like i've lost anything

--Jakk:t

[dragflameson]

Let it run for a week or so then try to get some more FSB ;)

See, my HSF you can literary hear from the opposite end of the house when my door is open, and on top of that, we keep the central air at 71 which is kind of chilly.

I'm running the SLK 900-A heat sink with the Vantec Tornado 80mm - Loud, but keeps it cool.

[smokinyoda]

Working on my first OC with similar chip so figured I would share my success. I'm running a 2500 Mobile on a MSI KT3 Ultra2 with 512 pc2700 valu ram. After a few hours I am running 2311 stable at 50c under load. Unfortunately I cannot get the board's FSB to the 200 point others are hitting but 2.3g is still not bad for first attempt IMO. 14X165 @ 1.57 volts. I am using ceramique so after a few more cycles temps may drop more. Also a coolermaster aero 7 HSF with controler set at half way point (2136RPM) so still have room to play. Anyone else using this board? Just curious as to my limit.

[Someone Stupid]

Your ram is to slow and being value, it may also be horrible latency wise, so that is your FSB killer there (and depending on the brand, the solution may require a new stick of solid stuff), you'll have to bump up the multiplier for anymore gains instead of FSB to keep the cpu and memory in sync (which you want to do).

[smokinyoda]

Unfortunately my board only supports pc2700. Would I see much of an improvement if I got a matched set of 2X512 pc2700 in games? Have thought about it but wanted to wait for next upgrade when I scrap out the board so I can get pc3200 or better. Still 2.3 is not bad is it? Lot better than the 1.7 I had with my old XP 2000.

[Someone Stupid]

You'd see improvement with another stick of 512 - it doesn't have to be matched, it just has to work with the board. Dual Channel only boost throughput to the CPU by 5% at best for Althon XP systems, so I wouldn't get it for dual channel, but 1 gig will speed things up in the fact that you do have more physical memory and new games really like that.

[dragflameson]

I'm running dual channel PC3500 OCZ EB series - its nice :D lol

smokinyoda, it does have to be matched speed wise if you where to get another stick... unless you like to waste money :)

Someone Stupid means if you get another stick it dont have to be matched brand name wise, or size wise, but you should still match the PC2700, if you bought anything faster than 2700 it will still only run at 2700 which you might already know ;)

[Someone Stupid]

Yes, if you want to get technical, you are limited to the slowest stick, but I figured that was obvious, not to mention you'll run at the higher of the two sticks latencies, even with unmatched pairs this isn't much of a problem, it is just a marketting gimmick. I've yet to see two individually bought sticks (or four) fail to work not being matched long as the sticks all test fine.
