Hi all,
my current setup:
Asus P5E3 Premium X48, 0605 BIOS
Intel Q9450 quad core with Noctua C12 cooler
2GB OCZ Platinum DDR3 Rated 8-8-8-24 @ 1800MHz
BFG GTX280 OC2
2 x Samsung Spinpoint F1 1TB
Creative Labs SB X-Fi Xtreme Music
Be Quiet Dark Power Pro 750W
Vista SP1 32-bit
I had this problem a few months ago but didn't look into it much and just left things running at stock because it was a fairly grunty system anyway. But I've had a play around again with overclocking and it's just bugging me:
I've got the FSB set to 400MHz, CPU @ 3.2GHz. I have the DDR3 running at 1600MHz, 7-7-7-20 timings, 2T command rate. All voltage settings left on auto, I have only changed the FSB and memory timings manually. I have not adjusted the Asus AI Transaction booster, that's still on Auto.
I've run a 1 hour Mix test with OCCT and it came back totally stable (I know this isn't a catch-all and maybe a longer test is appropriate but it's a reasonable indicator to start with, I think). Currently in normal windows use all seems fine. But as soon as I tried to run 3D Mark i got a BSOD after about 20 seconds. I've repeated and same results.
Previously I had a P5Q3 Deluxe, which sadly died on me, but for 4 months had the CPU running at 3.2GHz and RAM at 1600 7-7-7-20 on this board with no problems. At this point there was an nvidia 8800GT graphics card and a Seasonic S12 600W PSU. Therefore I can't see the CPU being a problem as it proved stable at 3.2GHz for several months, and it seems fine in general windows use.
The changes then are the mainboard, the graphics card and the PSU, but the PSU is well reviewed and more powerful than my old one which should be fine for the GTX280. I've disconnected 2 old 250GB hard drives to reduce power draw.
When I've tried previously it also caused the nvidia display drivers to fail, but seemed to work a little better with the DDR speed set to 1333 instead of 1600.
So I'm wondering if the more powerful graphics card combined with the overclock is causing too much power drain, hence the crashing. Or maybe the motherboard just can't cope - but it's allegedly a better board than the one I had before, which ran fine with the overclock. Or perhaps I have a faulty PSU? Or the graphics card just doesn't like running with the memory set to 1600MHz for some reason? (I might go and try dropping it to 1333 again to see if it works)
Anyway, apologies for rambling message, hope I included enough detail!
Thanks for reading
If anyone who's more of an expert than I has any ideas here, I'd be really grateful!
