cmf0106 Posted October 12, 2008 Posted October 12, 2008 (edited) First thank you for taking the time to check this. I am currently running with these settings trying to achieve a 3.8 OC on my q9550 (stock 2.8). FSB- 1800 CPU-8.5x Link and Synced 5-5-5-15-2T CPU- 1.375v FSB-1.325v mem-2.1v SPP-1.45v MCP-1.6v SPP-MCP- 1.4v Idle temp: 38 Load temp: 55 With this the system performs marvelously in Prime95's small FTT stress test. But when I try to run a prime95 Blend test, it only lasts about 3 minutes until encountering a fatal error typically on thread 2 or 1. The error reads "fatal error rounding was .5, expected less than .4" System Specs: Intel Q9550 2.8 Heatsink: Tuniq Tower EVGA 780i SLI FTW Nvidia GTX 280 x2 SLI G.SKILL 4GB (2 x 2GB) DDR2 @ 1066 SILVERSTONE OP1000-E 1000W ATX 12V 2.2 & EPS 12V Windows Vista 64 bit Edited October 12, 2008 by cmf0106 Share this post Link to post Share on other sites More sharing options...
crazy8s846 Posted October 13, 2008 Posted October 13, 2008 Turn your northbridge up to 1.4, and see if it passes, id say its your memory if it is passing small ffts, on blend it uses more memory. Turning your north bridge voltage up will help it coup with the high fsb of 1800 that you are running, if that does not work you might have to go to 1.5. Id keep moving it up from 1.4 till it becomes stable but not over 1.55. Share this post Link to post Share on other sites More sharing options...

Id keep moving it up from 1.4 till it becomes stable but not over 1.55. Mine is set at 1800 fsb and thats what my voltage has to be set at. actually i think i am at 1.45. Whichever one is before 1.5 (pretty sure the 1.5 text is in red in BIOS) Share this post Link to post Share on other sites More sharing options...
