CPU Multiplier Stuck at 8x after resume from hibernation

Hi,

I started noticing my computer being ridiculously slow sometimes, and tracked down the issue to the CPU multiplier being stuck at 8x after resume from hibernation. After a fresh reboot, it starts behaving like normal scaling up to 34x.

I tried updating the motherboard bios from v1702 to v1801, but not only the problem was not fixed, but now I can no longer use the XMP #1 profile for DDR4-2666MHz, getting no video and "bd" Q-CODE (which I think is unrelated).

Even with the normal profile 100Mhz bclock, the multiplier keeps stuck at 8x after resume from hibernation, as can be seen on this image:

This is very frustrating, as I spent a lot of money to get a computer with outstanding performance, and now I'm stuck with an 800Mhz machine every now and then. Is there any bios settings that could be incorrectly set to be causing this?

Check the computer power settings. There are 3 of them. After a while of slow or no activity the computer will slow down by default. Windows default power setting is "power saver." I go into each one and turn off all the sleep functions and wake functions in all three power modes. I do not like the comp doing anything without me telling it to. And I turn off the comp when I am not using it.

Playing games, the "high performance" setting should be checked.

Hi, thank you for your reply.

I have switched to the "High Performance" power plan, and disabled all sleep and wake functions, but the multiplier still keeps stuck on x8 after resume from hibernation. I really don't think "do not use hibernation" would be the optimal solution here, since the functionality is there, it should be used and work as expected. There's got to be some other config that fixes this.

You need to set the other 2 power settings too. When the comp wakes, it is in the power saver mode and probably parks some cores too. Playing a game is supposed to get the CPU ramped up to the "High Performance" mode. Like I said, I turn off all those options. I don't have a need for a sleep or hibernate option and really don't want them. I turn off the comp when I quit using it. My system has excellent boot & shutdown speeds with the OCZ SSD that I have. It is safer for the hardware to be shut down all the way than to still have current running through the MB all the time. Could be disastrous if power outages or even brownouts happen.
