Problems OCing 9600 GT - Page 2

post #11 of 19
To start with, is there an overclocked version of your card? If there is use those clocks. My card came stock at 650/900 but the overclocked version was 700/1000 so I started there. Now, slowly work up. Use ATiTool to make sure there are no artifacts or anything. I don't think many 9600GTs can go higher than 750 on the core but who knows.

This is getting annoying, did I get a bad batch or something? I can't overclock this card at all. A friend of mine thinks its artifacts, but I can't see how such a mild OC can cause the screen to flicker and after abou 5 seconds lock up. I don't know, i'm still new to overlclocking, so that may as well be the cause. =
GPU temp is 38 idle and 39 with OC.
Every card is different. What your friend got might not reflect the overclock you achieved. Can you link the exact model of 9600GT you have please?

No it's not the overclocked version. I just tried the OC'ed version specs, and it is stable as far as I can tell. I can run 3DMark no problems( with slightly higher frame rates). Guess i'll do what you said and slowly work my way up...
And I can't run ATITool because of vista and my drivers. It says the clocks are zero(0) and I can't run the 3d Model

I'm sure even though AtiTool won't recognize the clocks because of a lack of signed drivers, you should be able to run the artifact scan test.

This is the error I get. I tried following their instructions, but they are wrong. I can't find anything like what they say.

Well, as an owner of two eVGA 9600GTs, I can help you a bit. Basically, some cards seem to be better than others at OC'ing. Both of my cards are currently stable at 750/1860/1100 (core/shader/memory). Some people have gotten as high as 780/1950/1050. On my cards, shader seems to be the biggest problem. Putting it to anything higher than 1860-1880 for me usually causes lockups when testing. The screen tends to flicker, and then the system locks up. However, with a lower shader clock (say around 1800), I can OC the core to about 770-780. You may also have to lower the memory clock at this point to about 1000-1050. All in all, it seems like OC'ing eVGA 9600GTs is a bit of balancing game between the three parameters, and you have to figure out what seems to be the best combination for you. I do not really think that anybody can say what the best overall OC combination is, because it really depends on the games you play. For example, shader-heavy games would benefit from higher shader clock, where as others may benefit from higher core clock. I have no idea what the extra memory speed does really, if anything. Maybe somebody can shed a bit of light on this?

I can run stable at the superclocked speeds. Thanks for all your help guys, really appreciate it.

I just flashed my cards to the 62.94.11.00.07 BIOS that I grabbed from here http://www.mvktech.net/component/opt...rent,category/

This is a new revision of the eVGA 9600 GT SSC BIOS. With it I managed to OC stable to 755/1872/1100 (2200 effective) Had to flash one card at a time though (physically removed second card) using a bootable flash drive and remove drivers in safe mode after so I can reinstall them in normal mode, otherwise Windows starts but I get a black screen.

Gave me 15 more 3D marks

I beleive that memory speed isn't as important as core/shader so if you can lower your memory a bit to squeeze out more on the shader or the core then it would probably be worth it. I found that having lower memory and higher shader clock in certain games makes the experience much smoother and the games more playable. That could be total crap AFAIK but it seems to work for me in newer games.

And as for the 9600GT overclocking for OP, my card originally wouldn't even go near 700 core, started crapping out at 680 and my mem wouldn't go past about 950. I was freaking out, thinking, "NO! I wasted money on this piece of fecal matter that won't even OC 5% over stock!". After I used it at those settings for several hours, though, I tried overclocking again and found that I was able to get my current clocks and I'm still experimenting trying to push it higher.

I beleive that these cards require a bit of a burn-in period. I never noticed this with my 8800GTS 320 but maybe I also didn't OC it right away, I can't remember. Either way, clock it as high as you can, play some games, run some tests, for about a day or two, and then try again. You'll probably have better luck after working it in a bit.

Hope that helps.

Thanks for sharing your experience with memory OC. I sort of thought it does not make that much difference either, though I will experiment more. I actually flashed to a newer bios from eVGA 9600GT SSC and I managed to squeeze out extra 5 MHz on core

Now I am at 775/1872/1100 (2200 effective)
