Problems with ga-ma790gpt-ud3h

post #1 of 3
Thread Starter 
Ever since I got this board I've been having a lot of voltage issues.
The problem is, that no matter what I set my voltage to, it NEVER reaches that under load.

It's not vdroop, if that's what you're thinking.

For example, while overclocking, if I set my CPU/NB to 1.225v, and my CPU voltage to 1.4v, then move my arrow keys up to highlight CPU/NB again, it will show 1.3v as my cpu voltage.

Then, when I boot into windows, and check HWmonitor, idle and stress testing, it will sit at 1.3v.
If I select 1.3v, it will stress test at 1.225v. (and also when highlighting anything other than CPU VID in bios)

Now the odd thing, is while randomly browsing and doing crap in windows, it will go anywhere between the low voltage, and what I set it to, but it's NEVER at that voltage while actually using the cpu to its max potential.

I have no LLC in this board, I am running the latest bios (F4J, was running F4G before), and I have C&Q turned off + turboboost off (its the same with either one on)

So what the hell is causing this?

Looks like a BIOS bug. It may be due to poor coding or maybe a CMOS reset could help. This is the main issue, as the other one is related to Win7's power settings.

CnQ being off doesn't mean much if W7 isn't on "High Performance" power profile. On my board for example if I set "High Performance" with CnQ active in the BIOS the CPU will stay at full speed, "Balanced" with CnQ disabled in the BIOS - in Win it still reduces clock/voltage.

Windows 7 is always on high performance profile.
I did a CMOS reset a few weeks ago and that didn't help =\\

Either way, the board has been running my cpu stable at 1.225v stock clocks for about a year now, so I'll just wait until I get the crosshair IV to overclock =\\
