Hi guys currently been messing around with my Sli setup. Been seeing how many more Fps i can gain in Crysis demo. But came to hit a wall with a display driver failed. But have noticed that this wont happen when I lower Vid mem and raise the Gpu Clock. before i was trying to hit 725Mhz & 1.1Ghz mem :but at this speed the driver would fail. Now that i have lowered the Vid mem to 900Mhz i can hit 750Mhz plus, Anyone got an idea why this does this, I am running Vista Ultimate 32Bit I have read that it is a Poorly written Vista driver from Nvidia. "We can't solve problems by using the same kind of thinking we used when we created them"

First thing you should do is switch back to XP. Or dual boot XP and Vista. You really cant tell the difference from DX10 to DX9. Yeah, every driver for Vista is crappy. Vista has not matured yet and neither have any of the drivers. I really wish MS would just bite the bullet and release DX 10 for XP. Vista is crap. Have you tried this OCing setup in xp???

I currently own a 8600gts and im curious is the sli performance much better than just 1? AMD ATHLON X2 5200 2.6ghz; ASUS M2N-E SLI; 2GB DDR800 KINGSTON; ASUS GF8600GTS; Seagate 7200rpm 320GB;

Of course an 8600GTS SLi config is better than a single 8600GTS. But now that the 8800GT has hit the market, you'd be better off waiting a bit to see what happens to card pricing. The ATI HD3800 will debut soon (less than 2 weeks) & it will support DX10.1. Both the HD3800 & 8800GT will support PCI-e 2.0. Rather than buying a 2nd 8600GTS, you *may* be better off selling the one you have & replacing it with a better single card. Keep an eye on the prices & make your move when the time is right. Here's what Tom's Hardware recently had to say about Crysis & the 8600GTS: "....you should almost abandon the idea of running this game on an 8600 GTS!" http://www.tomshardware.com/2007/10...

Your probly right that Xp is much better off for the Ocing problem. But I got Vista Ultimate running all the programs i had on Xp pro. But waiting on Evga to do a step-up soon to the 8800GTs maybe ultra depending on my ego that day. "We can't solve problems by using the same kind of thinking we used when we created them"

I have ran the game fine with setting on med. just looking to see what setting push the card to get that extra edge outta my already ob-SO-Lite Sli config, But Xmas is right around the corner and i feel a whole new Build coming on. But Wish AMD would throw a wildcard out already. "We can't solve problems by using the same kind of thinking we used when we created them"

Here we go again ..... How is a software to blame for a hardware overclock anomaly? I guess any BSOD that happens on a buggered overclock attempt in XP implies XP is crap. Overclocking is not an exact science, it requires skill & often involve multiple trial & error attempts to fine-tune the setting for best results. In any case -- disappointments or setbacks encountered is not an indication of a software failure. And in this case, Vista is definitely not to blame.
