Opty 165/LanParty nF4 SLI-DR Expert: CPU Voltage Issues

post #1 of 7
Thread Starter 
Hi

I got some advice to manually set the vcore on my mobo to 1.35 (higher end of stock voltage for the Opty 165) to hopefully deal with the proc not being orthos (prime95) stable for more than 3 hours.

Raised vcore in the bios to 1.35 (prior setting was auto). When I rebooted the system, the voltage, as reported by CPU-Z is between 1.312v and 1.328v.

Question 1: Is CPU-Z a reliable method of measuring vcore voltages?

Question 2: If CPU-Z is a reliable method of measuring vcore voltages, is it normal for the Bios not to deliver precisely the voltage selected?

Question 3: If CPU-Z is NOT a reliable method of measuring vcore voltages, what method should I be using?

What do you think?

#1 no
#2 bios is normal to deliver the more precise amount of voltage, but its more up to PSU
#3 a multimeter

From what I experienced DFI's undervolt slightly (in your case a bit).

CPU-Z is not the most accurate. I use a series of programs to monitor my
cpu voltage: utilities: #1 bios: others>

SiSandra, Everest, Speedfan, SysTool, and a variety of others.

I'm new here (2nd day). Could you give me some more specific guidance as to where to find the links to these tools? I'm still finding my way around the site.

Thanks!

Google is a good place to start.

Majorgeeks.com has a lot of these utilities.
