Hello All,
I am running 2003 on the Maximus X Formula and an 8700K O/C to 5.0GHz.
I am concerned about my CPU VCCIO Volage and the CPU Systems Agent Voltage.
My RAM is the Trident Z RGB DDR4-3600MHz CL16-16-16-36 1.35V 32GB kit.
When I load the XMP profile both voltages run really high on auto.
I am seeing the below values:
CPU VCCIO Voltage: 1.440V AUTO
CPU System Agent: 1.424V AUTO
In Der8auer's Hero X Overclocking video, he states that the above values should be in the neighborhood of 1.24V.
With BIOS 1803 I was 100% stable at 5.0GHz, but now I am seeing a thread die in Prime95 small FFTs.
Thoughts and are these normal?
Thanks,
J
Hello,
It's best to read sticky "Understanding and using XMP". As it's stated over there:
"When enabling XMP it is normal and should be expected that the board will alter other settings as well as voltages. These changes are set up to accommodate the processors at the lower end of the lot sampled. Especially with voltages it is the responsibility of the user to change these values to amounts that suit the particular CPU and configuration being used."
So in short - running XMP at auto voltages will result in higher voltages than in many cases it's needed.
Try to get as low as possible, if I set 3200 and leave VCCIO and SA in auto there are at about 1.3 and other at 1.25. I can run my memory at this frequency at VCCIO 1.05 and SA at 1.10.
You need to check what's stable for You, in worst case scenario You may have to leave auto voltages so high to achieve stability.
