Anyone running an Asus P3V4X at 150+ FSB?

[AdamK47]

I got one of the newer P3V4Xs and have noticed that the 150MHz bus does work. The newer revisions of the P3V4Xs have the new clock generator chip. It doesn't give as many FSB selections as the original P3V4Xs with the ICS chip, but it appears to run at 150MHz stable with no required cooling of the clock generator chip. It has brought my Pentium III 650 to 975MHz with my 128MB of HSDRAM at 1/1 FSB clock ratio with 2-2-2-5 timings.

I had one of the original P3V4Xs and could not get the thing to boot up past 146MHz FSB. I returned it and bought the newer one with hopes that 150MHz would work, and it did.

I'm just curious, who here has a P3V4X running at 150+MHz FSB? Do you have the new clock generator chip or the old ICS version?

I have the original running at exactly 150mhz fsb(soon to be replaced by a Soyo 6Vca, though)... I have a heatsink on the ICS chip.

I was also at a computer show today, and there were a mix of both rev1 p3v4x and rev2's. I'd say it was roughly 3 originals to ever 2 revisions there.

I had my ICS-clockgen P3V4X at 150 FSB for a good while. It would also do 155 but not entirely stably. It would POST at 166, then crash. It would do nothing at 160.

I can only get mine up to 150 MHZ FSB als thinking about putting a micro heatsink on the Clock generator.

I have revision 1. I just wish it had some settings between 150 and 155. I can boot mine at 155 but my 650e isn't all that stable at 1007. Although it is completly stable at 150.

My version 1 tops out at 146mhz. Gonna try a heatsink on the clock generator, see if it helps. My 550e gets real hot at that speed even with a golden orb & 2 case fans, so I usually run at 133mhz (unless I'm showing off for someone) -- plenty fast for what I do.

I run mine at 146Mhz. BTW, I have a heat sink on my clock generator chip and it did not help any!!

Question guy's how do you know what revision you have ????

Mine run's at 150 fsb that puts me at 1050 mhz and its not all that stable. But it works flawlessly at 146 FSb = 1022 mhz. Its about 90% stable at 148 fsb but I hate my pc not to be 100%
this is all at 1/1 ram speed cas 2

I don't recall if the newer boards are a different revision # or not, but they have a clockgen chip from Winbond versus the ICS chip on the older ones. Somewhere along the line they also started using a newer stepping on the 596B southbridge chip, CE versus CD.

Hmmmm.... Really? I'm gonna have to check to see what stepping my southbridge chip is. My board is really new. It even came in the new purple Asus box.

I'm stable at 150 with the ICS chip. I had a fan/heatsink on the ICS chip for a while but then I realized my TNT was overheating and was the reason I kept getting bounced to the desktop while running 3dMark 2000. So I put the fan/heatsink that was on my ICS chip on my TNT card and I haven't had to cool the ICS chip to remain stable since.
