matt768 Posted July 21, 2011 Posted July 21, 2011 q9400 750i ftw 4gb corsair dominator 1066 5-5-5-15 1800 fsb RAM @ 800 with stock timings vcore 1.36875v fsb 1.35v ram 1.9v spp 1.45 NF200 1.2 GTL lanes are all on auto Now I can't even get this to do 1 pass on intelburn test. I've tried more vcore, fsb spp, played with the ram a bit and a combination of them and I just cant figure out why I cant get this even a tad more stable than 1 pass. I've also thought that maybe it was an fsb hole so I tried a few above and a few below. Any ideas? Share this post Link to post Share on other sites More sharing options...
IVIYTH0S Posted July 21, 2011 Posted July 21, 2011 (edited) What's the highest you've gotten the chip so far?? Is the RAM linked or unlinked?? It's been common knowledge that nvidia chipsets often overclocke rather poorly, especially with the C2Qs (I have personal experience of this as well....and I had a 680i and 780i board) If you want to do serious overclocking you'll be wanting a P45 board Edited July 21, 2011 by IVIYTH0S Share this post Link to post Share on other sites More sharing options...

Yeah I figured it was just the board + CPU combo. The RAM is unlinked and the highest i've gotten it stable is at 3.2 Share this post Link to post Share on other sites More sharing options...
IVIYTH0S Posted July 21, 2011 Posted July 21, 2011 Maybe try linking them and running them under their rated speed/timings What cooler are you running and what are the temps of everything while stressed?? Share this post Link to post Share on other sites More sharing options...

If I link them I can't run them at 1066. Temps usually always stay in the 50's range under full load. Share this post Link to post Share on other sites More sharing options...
IVIYTH0S Posted July 22, 2011 Posted July 22, 2011 don't worry about them running at 1066, run them slower for now. We can always work on that AFTER overclocking the Q9400...(overclocking memory isn't very lucrative anyway) so just link them, lower their divider, and then try clocking your chip to 3.4ghz Share this post Link to post Share on other sites More sharing options...

The memory frequency won't matter. IIRC those 750i boards generally aren't great for quad overclocking though. Share this post Link to post Share on other sites More sharing options...

The first 2 set the ram at 1400, 3:2 sets it at 1200, and sync sets it at 900. Should I just unlink them and lower it to say 667 or something around that speed?

IVIYTH0S Posted August 13, 2011 Posted August 13, 2011 Sorry, thought I answered. I'd run them linked at 900 Share this post Link to post Share on other sites More sharing options...
matt768 Posted August 14, 2011 Posted August 14, 2011 Sorry, thought I answered. I'd run them linked at 900 ran at 3.4 with these settings 1.38v vcore 1.35 fsb ram at 900 1.9v link and sync'd it made it 2 passes of intelburntest bumped vcore 1 notch, then 2, made it less stable then before, also tried 1.4 fsb.
