Those settings would work for me. There is a setting for "Boot Vcore" or something that can help if there is problems with getting the rig booted.

Unfortunately, not even these settings worked for me as my computer completely froze in place 5 minutes after starting Prime95:

361

I've been playing around with my BIOS settings and it seems the thing that's limiting me is the Core Voltage because the ONLY stable OC I can get at 4.625Ghz is with the RAM manually set to 1666Mhz, the Core Voltage at 1.38v, and everything else on Auto. Below are the stable results of over 9 hours of Prime95 with these settings:

363

You will notice the Core Voltage actually ranged from 1.38v to 1.41v, so it's not even a strict 1.38v and my CPU clearly needs to be able to go up to 1.41v to be stable.

Re-seating the cooler reduced the Temperatures but did absolutely nothing for the OCing as I am simply unable to get to 4.625Ghz with less than 1.38v.

Do I just have a dud of a CPU? A faulty motherboard? Crappy RAM? What is it and what do I do? I'm completely disappointed and I just feel like returning this damn PC.

where I can fin it? You mean in EZ flash utility?
I tried it but it says that bios isnt up to date

I would say, that your voltages are normal I have similiar results
4,750Ghz couldnt get stable under 1.395V

For all I know it's too high, I was using one of the preset OC configurations but it was at 1.4 vcore @ 4.375 rolleyes.gif

I haven't checked if I can lower it yet, I'll have to try and tweak it a bit.

your temps are in range.

i was thinking your Vcore was very good.....

what is the usual Vcore for 4.6 or 4.7???? (a spreadsheet will be great with all users in hehhe)

OK, something is definitely wrong with my PC.

I reset the BIOS to the "Optimized Defaults" + XMP @ 1600Mhz.

It failed Prime95 in under 3 hours:

363


If my PC can't even run stable with the BIOS Optimized Defaults, then there has to be something seriously wrong with it.

How can I figure out what it is and fix/replace it?

I'm so out of my depth here...please help.

Download the older bios from internet
Put file on a flash drive
Shut the computer down
Turn power on
Press del to go into bios
Switch to advanced mode
Go to Bios selection and load bios from flash drive
I can't break it down any simpler than that. If you aren't comfortable or aren't able to do that you should take your computer to someone who can.
