Hello all.
I have been experiencing a major problem with my CrossfireX setup. Essentially I am getting poor 3DMark06 results.
My setup consists of the following:
Q6600 (I think running at stock - see my comments below)
Gigabyte GA-EX38-DS4
2 x 2 gigs of 800mhz Corsair memory
2 x 250gigs SATA drives running in RAID0 of the ICHR9 onboard chip
2 x Sapphire 3870x2 with crossifre cable
1000W Thermaltake Toughpower PSU
Antec P182 case
Now I have spent probably over 26 man hours trying to sort out the problem. I have posted on other forums but am coming here to see if any assistance can be given (this is not to downplay the other forums I have posted on, but they are less the technical and do not have as experienced posters).
I have tried the following:
Placing both cards in, install OS, install SP1, install Cat 8.3 then other drivers (with necessary restarts).
Check CCC to see Cat AI on, Crossfire X enabled etc.
3DMarks06 read initially 9600!!!
After a day or two or trying different installation proccedures, installing one card at a time etc, I decided to O/C the CPU.
Interesting the Mobo read the CPU as running at 1.6ghz (instead of 2.4ghz), I up this to 2.4. I then installed EasyTune5 and saw that the CPU was runnign idle at 1.6ghz still. I set Vista power setting to maximum performance.
3DMarks06 now went up to 13330. An improvement for sure, but no where near the 18000+ plus marks others are achieving (on that point I am not sure if other results are mainly O/C'ed).
So, I am at my wit's end as what to do.
Is it (a) a bios/driver issue (b) hardware (c) some incorrect setting (d) faulty card / crossfire cable?
CCC recognises the 4 GPU's, so it appears not to be a hardware issue.
Some people suggested flashing the bios - the 3870x2's may have a clock issue i.e. incorrect read the 2D settings in the 3D settings.
Your comments are greatly appreciated.
