GeForce 3 and FSB overclocking

[Marine]

Can someone please point me in the right direction to help me figure out why none of my overclocked ASUS CUSL-2/E/EP/BP based machines will successfully run a GeForce 3 card? Got two GeForce3s, one Gainward (CardExpert) another by Ocie. One machine been running stably at 150 MHz with a GF2/GTS, the other at 150 MHz with a V770. Put the GeF 3s in and while both will run in 2D apps, as soon as there is a 3D call, the machines lock. Put the machines at default FSB and the cards work fine. Been a bit occupied lately with national security issues, maybe I've missed something. Don't the GeForce 3 cards overclock?

Curious....I've got my Asus CUSL2-C oc'ed at 150 fsb with a Visiontek GF3. Runs fine.

Well, I was running my Visiontek GF3 Ti500 fine at 153fsb on my Shuttle AK31 KT266A mobo.

Well, that's encouraging. On this CUSL-2C, I was running a PIII 1Ghz O/C to 1200. Everything was fine with the GeForce2 GTS card, no problems, stable as a house. So I bought a Gainward Cardexpert GeForce 3 card, and it installed fine, no problems. However, as soon as I tried to play a game, watch a DVD, the entire system locked up. After screwing around with drivers for much of a day, I reset the machine to the default 133 MHz FSB and the card worked perfectly.
On another machine, running a PIII 500E O/C'd to 750@150 FSB a V770 was working perfectly. I bought a new GeForce III/Ti500 Inno 3D card and same exact behavior. Fine in desktop, as soon as I tried 3D calls, machine locks up. Both running latest DirectX 8 in Windows 2000. Very disappointing. I don't think it's a heat issue, as the cases are well cooled and the crash is instantaneous, rather than after a few cycles of 3D processing.
Would be interested in anyone with this issue discussing possible solutions.

Is side banding turned on? If so you may want to disable it.

 

[Marine]

Thanks Acroig, but no, no sidebands. I think there may be an incompatability between the GeF3 and the CUSL-2 series in the Win2K operating environment when overclocked. I hesitate to say this, but I've seen it in every system based on these components. In spite of near heroic efforts, I've never been able to run a GeF3 card above nominal FSB on a CUSL-2 board in Win2K. A bit frustrating actually. Any suggestions are very welcome though.

hmm i seem to be running my gf3 ti 200 fine at 160fsb

TimidOCer,
Yes, but was your overclock on an ASUS CUSL-2 board? Thanks!

Did you disable fast writes in the in the bios(or powerstrip or nvmax whatever you use)? I have it disabled on my system, because it was causing instabilities at higher speeds, both fsb and core/mem speeds.

I have the same problem. A Cusl2-c ep with a 1G PIII. I was overclocking to 1185. Bought a BB VT Geforce 3 ti 200. Couldn't play games with it. Echanged the card, same thing. Quit OCing, and changed the soundcards slot, and I work fine. Sort of feel bad about wasting 185 mhz. Not sure how much I can overclock the VT, as I've just positively narrowed the problem down to ocing the bus speeds. Running 133 100 33 didn't help, just crashed my system at Boot time. (??)

 

[MisterL]

Yep, something to do with Win2000/XP. I loaded up Win98 while overclocked to 1185 and had success.

I sure would be interrested in any ideas in fixing Win2K/XP so I could overclock with the GeForce 3 ti200.

thanks in advance
