Ok finally I've managed to get some results. I installed the 3Mark2001 patch and it ran. I left everything at stock speeds:
2.6GHz
200 FSB
DDR 200MHz (400 in DDR) 2.5,4,4,7
9600Pro 400-clock 598-mem
3DMark2001 11463
So after installing DX9.0b and the Cat 3.9s I've only got a small increase. (See original post for specs and scores)
So on with the overclocking.
3.02GHz
232 FSB
DDR 186MHz 2,3,3,7
9600Pro 500-clock 598-mem this card really overclocks well.
3Mark2001: 13314
A nice increase. So I pushed it a bit more:
3.18GHz
245 FSB
DDR 196MHz 2,3,3,7
9600Pro 520-clock 598-mem not sure how much higher this will go.
3Dmark2001: 13556
It seems from fiddling around with settings that the CPU speed has a marginal effect on the score. The biggest increase seems to happen when the card is overclocked.
When I tried to o/c the FSB higher than above 3Mark would crash to the desktop. Also occasionally it would hang altogether forcing me to reboot. I tried to vary the settings to see if it was the gfx card, cpu or RAM causing the problem but i felt the crashing and rebooting was bad for the system and gave up. I'll try more at another time.
I decided to go try the system o/ced to 3.0GHz and play a few games. Loading up Neverwinter nights I found it would hang after a few seconds of play. This was never a fixed point but occured after a very brief period. This was unusual as NWN had never crashed on me o/ced before.
I dropped the speeds down to stock but it happened again. I tried to check few other games, Morrowind Halo etc but same result. This was really bugging me as I now had good speeds but no stability.
I uninstalled and reinstalled the GFx drivers and now *fingers-crossed* everything is going ok. One other problem was playing a DVD it crashed after about 30mins and blue screened telling me a hard disk error?!! Did chkdsk and hopefully this can be avoided again.
I have also installed the Call of Duty hot-fix and I agree with what someone mentioned above it does seem to fix problems with anumber of other games. the 9600pro seems to stop responding to driver instructions and hangs during a game. It usually crashes to desktop, informs you of the error and then sometimes lets you return to the game! sometimes not. haven't had this in a while so maybe it has been solved.
Lastly a few questions. After o/cing the system i found it would boot to the desktop but occasionally would crash during a game. When it crashes is there any way of telling what caused it? Sometimes it crashes to the desktop other times just hangs.
Is there a log where I can look up what caused it? What is the best program for checking stability? I'm looking for something to test CPU, ram and card? Stress thema dn show the stability? I've heard that if you overclock the gfx card and see something called artifacts then its running too fast. What are these and how do i check for them. Also any advice on what i should try do to improve stability would be great. I should point out that the crashes I have experienced have mostly gone away but i haven't been using the system long enough to test it.
forgot to mention my temps. overclocked the CPU at load doesn't seem to get much higher that 45c with minimal cooling. The PSU seems to get up to 63c. I'm happy enough with this.
