Find Max GPU feature crashes my computer

[stoopdapoop]

Hey guys, I'm running a core 2 duo E6300 and I have an X1900XT 512 GPU, whenever I press the "Find Max Core" or the "Find Max Mem" button I crash I can supply with any necessary information, but is there some kind of setup that I need to perform before I can begin?

System specifications would realy help in finding solution to your problem. For starters what is the make/model of your PSU?

I'm running a core 2 duo E6300 at 3Ghz, 2 gigs of G.Skill PC2-6400 ram running 4-4-4-10 latencies. and A Saphire X1900XT 512 meg card.

My power supply is a 450 Watt Antec but It has a decent amperage on the 12 volt rail. I doubt that the power is the problem because it doen't even start the test, and without it I can get it up to 688 mhz core.

what do you call decent. That card needs a minimum of 22 amps on the 12v rail. Could also be a driver problem. What driver version are you using and what version of ATI tool?

BTW your PSU specs show that you have a duel rail PSU with one 15amp rail and one 17 amp rail, here's the link.

When you start find max core, how long does it run before it crashes.

sorry for the delay, I was in the Bahamas for a week. But It doesn't run at all, it crashes Immediately, the button doesn't even unclick.

oh and thanks for the info about the PSU, looks like I was wrong

Hello. I have this same problem.
I have a similar card. Before I continue, here are my specs:

Athlon 64 X2 4800+ @ 2.57ghz
Corsair XMS DDR 400 @ 234mhz
HIS ICEQ x1900xt 512mb
Thermaltake Toughpower, 700watt.
3 HD, 2 optical, SB Audigy, 5 case fans.
(Software: Winxppro, cat 7.2 w/ ATT)
(ATi Tools 0.26, Hotkey poller disabled...)

Ok. This powersupply, I am certain, is more than enough for this system. I could get away with a 500watt one if it was a decent ps...

Now the same thing happens to me; in ATiTool whenever I change core frequencies while in the 3D View, OR when I try to "Find Max Core," the system black screens immediately, and the system is not recoverable. I have a very similar problem with ATi Tray Tools, wherein I cannot change frequencies while in "Low Level" mode.

I cannot fathom what the problem is. I have used ATi tool on a 9600xt, 9800pro, g800gt, and this card. Only this card has caused any problems...

Help?
