First attempt at Overclocking my E8400

[Mishtar]

I have a laptop set up now next to me so I will try what you suggested but I have f9 beta as my bios. Hope that does not make a difference.

Edit: Flash to most recent BIOS.. still F8f as far as i know.[/quote]

As 1Tanker said dividers are under System Memory Multi. 2.00 should be 1:1

Shouldn't matter... i think the F9 beta just has microcode revisions to recognize E0 Wolfdales, etc.

Ok I am a little lost. If 2 is a 1:1 setting what is 3? there is no 1, just 2, 3 , 4 and such.

Also if I go up to 445x9 to get 4ghz the memory freq says 800 on the left and 890 on the right is that ok?

Also soomeone said
"I see you also have speed step on, to keep it from throttling turn off EIST and C1E in the BIOS."

I see a CIA2 but no C1E and no EIST

Ok here are some screen shots of temps and voltage and such and one of what the memory is doing. I have no idea wtf is up with the memory lol it use to show 4-4-4-12. I have only run this for 15 mins or so on Orthos so far but I am going to step out and let Prime95 run for an hour or 2 as a quick test.

I think I set the vcore at 1.35 and did the 445x9 for 4ghz.

Did you put your memory timings on auto? You have to manually set em to 4-4-4. For speedstep disable:
CPU Enhanced Halt (C1E)
CPU EIST Function
CPU Thermal Monitor 2 (TM2)

CIA2 is Gigabyte's own OC feature. Don't use it.

The ram multis are just that: take the FSB set, and multiply it with that setting. Ex. 2.0 x 400 FSB equals the speed at which the ram will run. 2.0 x 400 FSB = 800 MHz.

Speedstep: you will find the settings in the Advanced BIOS Features menu. It's called C1E, TM2 and EIST. Disable all 3.

edit: Damn 'donko, you beat me to it again!

Ok thank you I made those last few changes and will now run prime95 while I go out for a bit. I will let you guys know how it goes. Thank you again!

[Eldonko]

No worries, enjoy 4Ghz.

Ok I ran prime95 for 3 hours and 20 mins at 4ghz with the Memory set to 4-4-4-12 and 1.35V. Everything seems stable so far and my highest temp was 64c. My idle temps are now sitting around 40c. So are those temps ok for 4ghz? 40-64c. Also now that it seems stable I can try to back off the volts a bit correct?

If this is all good I will be trying the video card next;)
