P3-600e@900mhz good on a Abit BE6 but no go on my new Asus P3V4X - why?

[plucky duck]

Is it because the asus mobo isn't as stable @ high FSB speeds?

It's not the video card, cause I've tried both AGP and PCI. Also had the ram set to 4/3 and AGP @ 1/2 speeds.

It can't even post @ anything higher than 142mhz FSB. The cpu can post and partial boot @ 150mhz FSB on my old BE6.

Tried both jumperfree and manual dip switch settings, but to no avail http://sysopt.earthweb.com/forum/frown.gif

Getting some new infineon PC133@150mhz dimms but I doubt that would help since this mobo has +/-33mhz SDRAM/FSB settings.

Also, where do I look in Windows to see which via 4-in-1 drivers I have?

Thanks for any help in advance guys/gals http://sysopt.earthweb.com/forum/wink.gif

Later,

Typical...I've got a P3V4X coming for my 600e which is at 857 on an i820 mobo in the hope of getting it to hit the 900 mark stable. I even went and got a vos32 cooler. Well Plucky you just burst my bubble http://sysopt.earthweb.com/forum/frown.gif. I'll keep you posted as to how I get on when I get it which will be next week now http://sysopt.earthweb.com/forum/frown.gif.

I got the same problem, I'm @840 but cant get to 900, got alpha P3-125 cooler and paste wont post, I thought it was ram timing or pc 133 I bought aint 133?

If you got the 4 in 1 drivers from the CD, you have 4.17

The newest version is 4.20 but it really kills agp performance. http://sysopt.earthweb.com/forum/frown.gif

I know exactly what your problem is. First open your case. locate ram slot # 4. See the little black chip beside it. touch it. I dare you, betcha you cant keep your finger there for more than 3 seconds. This chip is the clock generator and on this board it gets extreamly hot. so when you set higher clock rates it generats more heat. Slap a little piece of heat sink on there. and you will be back in bussiness. Also remove the big GREENY on the northbridge chip and slap some paste down and put the GREENY back. you will now be able to overclock to your hearts content. this board is exelent save for a few anomilies that can be delt with if looked into enough. This inability to set higher FSB has been termed Phantom Bus Speeds. 140-150 seemed to stress the generator more than other settings so it would over heat and the chip would not over clock. best of luck. this does work.

"Is it because the asus mobo isn't as stable @ high FSB speeds?"


I have heard this many times over.

I'm running a 550E @ 803 MHz on a p3v4x, that's a 146 FSB, it's just as stable as at 550, I'm running a flip chip on a generic adapter, an Alpha PEP66, and I'm using Crucial PC133 RAM, I haven't tried it any higher this is my business machine and I can't afford for it to crash, I did flash the bios with version 1004 beta 2.

Before I got the Alpha cooler and flashed the bios, it wouldn't post above 770, (if you booted into windows, say running at 770, and then hit the restart button, and went into the bios and changed the FSB to say 146 you could run stable all day long over 800 MHz, playing games ect. but it wouldn't post, once I put the Alpha on and flashed the bios, I can run at 803 just as stable as at 550, although I did have to raise the core to 1.7v, at 770 MHz I could run at 1.6v).

If you had your 600E running stable at 900 MHz why did you buy a new mobo, what did you hope to gain? (I have not heard of anyone running an Intel chip stable, at higher than 150 FSB.)

He was probably looking for 1/2 agp divider.

Hi,
I have got my 600e up to 960 using a water cooler folled with ethanol the chip is stable i have an intel vc820 m/b with 256mb of rdram the systen never gets above 33c i also have lots of cooling fans for everytheng so every thing is nice and cool my next project is to get a 1ghz p3 to at least 1.5ghz but that is a long way off.

[plucky duck]

perdactyre, thanks for the info http://sysopt.earthweb.com/forum/wink.gif

I try slapping a heatsink on that chip. Any stock heatsink shoud do, correct? Since I have a tower and the mobo is vertical upright, what's the best way to apply the heatsink and keep it there besides superglue?

Here's another question, how do you take out the greeny heatsink on the northbridge chipset?
Any easy way to get it out without damaging the mobo?

On a side note while I've got your attention:
Do all i820 intel camino chipset based mobos have the so-called MTH device? Are all i820 mobos defective or only a select few.

My bro wants to get an i820, but don't know which one is a sure win safe bet.
Any insight is greatly appreciated http://sysopt.earthweb.com/forum/smile.gif

All i820 have the MTH but Supermicro say they have taken steps to reduce the noise so there boards are not affected and I have not had one problem with mine. But I ordered a P3V4X and it came today. I had my 600e@857 1.65v on the Supermicro P3SCD but now I got it at 875 (146x6 1/1) 1.7v and it rocks.I was wondering whether or not to flash with the beta bios and how to enable 4 way interleave easily (does the beta bios do it). All I got when I went higher than 146fsb was a black screen even when raising the voltage but from what I hear this is quite common in the 144/150 range.

Oh and Krusty I used a set of pliers and squeezed the ends of the clips from behind while pushing gently and the sink came of no problem...I stuck some paste under it as soon as I had it out of the box coz I thouht it would mean taking the board out again to do it at a later stage. Hope this helps http://sysopt.earthweb.com/forum/smile.gif.

Mr Duck, my mobo is in a tower to. I plan on using some kind of thermal tape. perhaps there is two sided thermal tape. I would not be so scared of using a small amount of glue in each corner. a heatsick will never hurt anything. and at least it will be better than what you started with. bascically use your imagination. but dont do anything dumb. as for the greeny thats easy. remove the mobo. flip it over. with a pair of needle nose pliers skweez the white plastic end together and gently push it back through the hole. just use cuation.

[perdactyre]

did any one try touching the clock generator, chip. see my post above. That is 90% of the problem.
