Volts Question: E8400 to 4GHz. - Page 2

post #11 of 41
Thread Starter 
ARGH I can't get this thing stable past 3.5 now. I've had my NB volts at 1.39, my vcore at 1.33 and it's still not stable past 3.5. What am I doing wrong I'm running it unlinked so my RAM is at 800mhz, and I haven't touched the volts for it. Could that be my problem? Or should I just try push the vcore more?

Link you rams and see if you ram voltage is at 2.1v. That way you run rams at 1:1.

So I should try it linked instead of unlinked? Should I change any other voltages apart from my vcore if i run it linked?

Just running your RAM at the lowest Ratio, 5-5-5-15 timings, at 2.1 or 2.2V should make it so your RAM isn't the thing holding you back.

Check what voltage your ram is running. The Geil's take 2.1v-2.3v.

I tried running it linked at 1:1 with my ram at 2.2, NB at 1.4, vcore at 1.3+ and it wouldn't even post. I tried unlinking again and running ram at 800 but still won't even boot at 3.53+, and if it did it would freeze before it fully started up.

I have to go to bed anyway, damn work tomorrow. Maybe I should give my cpu some more time to settle before i push it. I've only had it a few hours, lol.

My temps are all fine too, I have no idea what I'm doing wrong. Little bit disappointed Thanks a lot for your help so far guys.

EDIT: I just noticed in my BIOS that under a different tab (Power > Hardware Monitor > Vcore Voltage) my Vcore is set 1.21... and the only other option I can change it to is "ignored". Should I change that at all? CPUZ says my cpu is at 1.225 but my BIOS in my cpu volts bit is set at 1.23. Pretty sure it doesn't change from 1.225 in CPUZ if i go higher, either.

Had my 8400 stable at 3.9g 1.39vcore (bios) , get into windows 1.36vcore (.03vdrop) , + .02-.04vdroop (1.344-1.322vcore) during prime 95 stressing. Just lowered it back to recommended 1.36 vcore in BIOS , 1.32 in windows , 1.318 prime 95. Still at 3.9g , prime didnt last 45 seconds lol. If that helps you any. MCH +.1v , DDR +.3v 5-5-5-15. Going to have to downclock or run at 1.39 which im scared to 24/7. When intel says reccomended 1.36 vcore , is that in BIOS or in Windows?

The voltage in windows is the one you should worry about the one in windows is the actual voltage going through your cpu while your BIOS Vcore is just what your board thinks it is putting out
