Sabertooth 990FX R2.0 different CPU Voltage on restart

post #1 of 4
Thread Starter 
Hello,

maybe anyone noticed this also..
I have the 2005 Firmware installed and use/overclock an 8350 and now when i set the CPU Voltage, it gets lower after waking the PC up per Wake on Lan.

Detailed.
I go to UEFI and set CPU Voltage to 1,45.
Then save and Exit and let Windows start.
I start HW Monitor and Prime95.
I see that the Voltage goes up to 1,50 on 100% Load and also the temps go up to 69 C

ok.
Then i shutdown windows.

Then start it with Wake on Lan.
Start HWMonitor and Prime95
Now CPU @4500 is also stable, but HWMonitor show 1,38 Voltage on 100% CPU Load and Temp goes up to 56C



Now, when i set 1,38 Voltage in UEFI > save and exit > let windows start, the CPU is also stable

But when i shutdown and awake the PC with Wake on Lan, the CPU is no longer stable because the voltage is now about 1.3 or 1.32.. so its too low.

So why is the voltage different when awaking the PC remote then starting windows direkty after making changes in UEFI?

That is SO weird that I would almost HAVE to assume that you are overlooking something somewhere... I would start by resetting the BIOS. I would even go as far as removing the CMOS battery for several minutes too. Do that, then reset the BIOS, just to be sure. I really dont have any other advice currently, but perhaps this will at least serve as a bump.

Oh, and I would definately update your BIOS. I can only assume that the 2005 listed above is the version number of the BIOS and not the release date...

yes.. weird..

i tried now a little bit.. checked the c1e, apm and all energy features are disabled.

is just when awakening from lan.
when i shutdown and start with pushing the hardware button, its running with the configured voltage. rolleyes.gif

will try the reset another time and will update when it solved it..
if not.. i think i could write to asus smile.gif

2005 is the bios version yes. and it is the latest

thanks

so.

reset bios and use Stock settings, there is no voltage issue.

Just with ovreclocking ans WOL.

Asus said, they will leave if there mind, but as they give no support to overclocking, they will not investigate further.

So. for me is a UEFI Bug. However. when not OC its stable.

greets
