O.k.., so I origianlly thought that this was an XP-x64 issue... but after putting regular XP on my computer, that pretty much went out the window.

Here is what is happening... if I overclock my 7900GS with the nvidia control panel (after coolbits is enabled)... if I overclock the memory at all, the screen will get corrupted... from 660, I can only go to 720 with coolbits... and even then, a few jacked up pixels show up on the screen.. but it passes the test... once I refresh the screen of move a different window over the places that have the jacked up pixels... they will fix themselves... and 3D programs run fine... no corruption or lock-ups or anything at all...

Now, here is where it gets weird... if I use ATI-tool... I can stick the RAM up past 800... if I try to do that with coolbits.. the screen gets really corrupted and I have to restart my computer...

But if I set it with ATI-tool.... it runs fine... no corruption at all in 2d or 3d.... can play for hours on end....

And, if I go into the nvidia control panel after setting the speed with ATI-tool.. it correctly identifies the speed at which it is set.

This happens with 91.47, 91.48, and 92.91 driver sets... I haven't tried any older driver sets...

I did try a much newer BIOS on my card, and that didn't help either.

Could it be something to do with the delta clock on the newer cards??? could that be screwing it up? I haven't tried changing the delta clock to 0 in the bios and then reflashing... my understanding is that the delta clock only affects the GPU clock and makes it run that many Mhz faster than the bios clock is set at... but even that doesn't make any sense... and I do know of some cards that come with the delta clock set to 0...
 
yep... ati-tool (get it from guru3d.com)... is more of a general video card overclocking utility...
 
cool thanks, i basically need any overclocking utitlity that might work in vista...
BTW: sorry for going off topic

Are overclocking the memory and the GPU? With Coolbits? With ATI Tool?
 
Are you sure the ATItool clocks are actually sticking?

Bench it at stock with 3dMark06, and then overclock it with ATItool and see if you actually get a marked increase.

I dont know if ATItool knows how to handle the GS yet.
 
well as far as I know, ati tool dont work for nvidia cards, but i maybe wrong...
 
I can overclock my 7800gt with ATI tool :). The newest beta at least. It doesnt always stick when I restart, so I use coolbits.
 
ATI Tools says my 7600GT has 0 pipelines and 400MHz memory, so I'm not trusting it with overclocking.
 
well... it does bench higher when setting with ATI-Tool... benches the same as when I set it with coolbits.

And yes, I am overclocking both the core and memory.

Also... it seems to overclock fine if I use Rivatuner also.

It seems to be an issue with only coolbits.

I should try rivatuner again... I'll post back with results
 
yep.... it is overclocking the card...

3dmark05 scores at 1024x768 are:

450/660 - 7518

570/800 - 9143

So... I have no idea what is going on with coolbits... but it certainly is screwing with my card... especially since both ATI-Tool and Rivatuner let the card work fine at the overclocked settings.
 
ok... so with Rivatuner... I can go all the way to:

590/835

This gives me 9507 in 3dMark05.

So... I can get 20Mhz more for the core and 115Mhz more for the RAM using Rivatuner instead of coolbits to set the clocks...

Is this freaky weird or what?

I wonder if coolbits is jacking with timings and not just the clocks.

Now I am really curios to see what happens if I overvolt the card..
 
After rebooting (after installing ATI Tool) any apps that accessed video drivers (including dxdiag) made windows lock up for a minute and reboot. Eventually was able to fix with a restore point. Not happy, will never use ATI Tool on a non-ati card again.
 
well... originally I thought that was the problem as well... then I wiped and started over from scratch... still the same problem with coolbits... Rivatuner is what I am using now as it actually will load your settings at atartup... or at least it is supposed to... as for right now, if I set the memory over 800, it will only load the overclocked core setting and not the memory setting...

I am thinking that Nvidia did something to the drivers that is screwing stuff up.

I really need to vmod the gpu and memory on this card and see what it can really do (max load after custom made heatsinks and shrouf/fan setup give me a load temp of 46C at 590/835 :-D
