SMeeD Posted March 30, 2009 Posted March 30, 2009 Im having some issues stabilizing my system. 20 seconds or less into Orthos blend my system will restart, BSOD or throw a rounding error. I can run small FFTs no problem. I did 2 hours with these settings and I even ran it for 8 hours last night on stock NB voltage and a higher vcore. Im running my RAM underclocked on a 1:1 to try and get rid of that variable. Here are my current settings.

Waco Posted March 30, 2009 Posted March 30, 2009 I'd start by raising the NB voltage a bit since that's where the memory controller is. Share this post Link to post Share on other sites More sharing options...
Turophiliac Posted March 30, 2009 Posted March 30, 2009 my quad can run all day on a small FFT test, and fail a blend test within 10 minutes... the small FFT test just doesn't stress the CPU like normal work does. I second the bumping of the NB voltage. Share this post Link to post Share on other sites More sharing options...
SMeeD Posted March 30, 2009 Posted March 30, 2009 my quad can run all day on a small FFT test, and fail a blend test within 10 minutes... the small FFT test just doesn't stress the CPU like normal work does. I second the bumping of the NB voltage. I bumped the NB voltage up a little more and still no luck. Like you said about small FFT Im beginning to not trust it. I stole someone elses BIOS settings and raised my vcore a little more and Im have more luck. Currently 20 minutes into blend but I wont hold my breath. I just want to not half . an overclock for once in my life and play eve haha Share this post Link to post Share on other sites More sharing options...
Turophiliac Posted March 30, 2009 Posted March 30, 2009 yeah, how high is your NB voltage? Mine had to be 1.4v to even boot my E8400 at 3.8GHz. Share this post Link to post Share on other sites More sharing options...
SMeeD Posted March 30, 2009 Posted March 30, 2009 I think I set it at 1.35. I was under the impression most people got to 400fsb with much lower so I didnt really experiment with it. I set my vcore to 1.30 but disabled LLC so once you take the vdroop into account I really didnt go up much. Im 2:45 into blend but Im not going to say anything simply because of Murphys Law.

tkrow21 Posted March 30, 2009 Posted March 30, 2009 Bad RAM? It's what happened to me. Share this post Link to post Share on other sites More sharing options...
SMeeD Posted March 30, 2009 Posted March 30, 2009 Bad RAM? It's what happened to me. I assume they are fine but at this point Im not going to declare it either way. Its ran at its rated speed in the past but with different settings. Share this post Link to post Share on other sites More sharing options...

I say don't ever use LLC, it bypasses a good safety measure for no gain whatsoever. I'm going to say that if you still don't pass a blend test to up your NB voltage even more. Most motherboards can handle up to 1.5v or 1.6v, as long as you have decent cooling, of course. Share this post Link to post Share on other sites More sharing options...
SMeeD Posted March 30, 2009 Posted March 30, 2009 Well Ive hit the 4 hour mark, which is a giant improvement over rebooting 2 seconds in. Ill have to write down my BIOS settings and then run it again with my RAM at stock later on and see if I run into any problems, if I do Ill move my NB up more and work from there.

shiver_8 Posted March 31, 2009 Posted March 31, 2009 Try for 4.5ghz. My e8400 does 4.2ghz 24/7 stable pretty easily on the same board as you with only 1.4 real vcore. With a 10x multi and higher stock speed the e8600 should be a cakewalk to get to 4.5ghz... I get my e8400 to 4.5ghz pretty easily, but my Xigmatek cooler can't dissipate 1.45 volts of heat efficiently enough. Go for it though, I have the same mobo and obviously similar cpu if you're having troubles I can help you along the way Share this post Link to post Share on other sites More sharing options...
