Everything in this list is disabled: C1E Speed step Execute disable bit My Q9550 is overclocked at 4.0. I am able to boot into Windows, I go to run some stability tests: I run Prime95 to test it out. My idle CPU temps are 40, during load my temps are no higher than 60 and about 5 minutes into the Prime95 test I get a BSOD. What settings to I need to change to get a stable system?

troy5061 Posted October 11, 2008 Posted October 11, 2008 1.45v is alot for a 45nm quad especially if your Q9550 is an E0. My Q9450 will do 3.8ghz on 1.32v, Prime95 stable for 2 hours. I havent let it go any longer because the temps are too hot for me. Im just using cheapo best buy silver compound, I need to get some AS5 before I put it at 3.8 24/7. At 3.6ghz I need Cpu Vcore 1.26v NB 1.33 SB Stock Ram 2.1v 5 5 5 15 Cpu VID 1.26 3.8ghz Cpu Vcore 1.32v NB 1.41 SB stock Ram 2.2v Cpu VID 1.3v Your board is quite a bit different but I wouldnt run more than 1.36 Vcore in bios if I were you, you may be able to put it a little higher to get 1.36v in windows. Still I wouldnt think you would need more than that. Everything looks good except for your Vcore looks way high. Turn that down to 1.3625. BSODS in Prime are usually a ram issue. You may want to run memtest to check that first. If I were you I would set your ram timings at 5-5-5-18 being 1066 and especially running 2 2gb sticks. You may be able to run 5-5-5-15. Definetly sounds like a ram issue to me. Share this post Link to post Share on other sites More sharing options...
Queenz Posted October 11, 2008 Posted October 11, 2008 Try loosen those timings to 5-5-5-15 or 5-5-5-18 and see if that helps. And did you set the FSB strap so that it's at 1:1 ratio? Share this post Link to post Share on other sites More sharing options...

Ive tried 5-5-5-15 2t and no go, and the FSB and RAM are linked and synced if that helps Share this post Link to post Share on other sites More sharing options...
ccokeman Posted October 11, 2008 Posted October 11, 2008 You can bumpt the MCP volts a little more but 4G is tought o get with many quads without an unlocked multiplier(higher than stock) Share this post Link to post Share on other sites More sharing options...

cmf0106 Posted October 11, 2008 Posted October 11, 2008 (edited) Ok I tried running this on Prime95, even lower temps now since I decreased Vcore from 1.45 to 1.36. Idle is high 30's load is mid 50's. Still BSODing during the prime95 tests FSB-1884 mhz CPU-8.5 Link and sink RAM RAM timings 5-5-5-15 2T FSB-1884 mhz CPU-8.5x Linked and synced RAM RAM timings 5-5-5-15 2T CPU-1.375V FSB-1.4V Mem-2.1V SPP-1.45V MCP-1.55V SPP MCP Edited October 11, 2008 by cmf0106 Share this post Link to post Share on other sites More sharing options...

DLS2008 Posted October 13, 2008 Posted October 13, 2008 I'm thinking it's your RAM. If you have it linked and synced, your 1066 MHz RAM is now running at 1884 MHz. That's a huge overclock on RAM. I'd try turning off the linking and syncing and see if that helps. 1066 MHz RAM doesn't usually have all that much overhead left. It might get to 1200 MHz, but 1884 MHz is too high.
