Post i9-7900X Overclock Questions


It's been a while since I overclocked and knew going with the i9-7900X would be a good challenge to get back into it. However, I think I've might've bitten more off than I can chew with this chip.

Here's the backstory... I sent my CPU to Silicon Lottery for Delidding and got it back. Right now, I am running the CPU @ 4.3 GHz and the voltage is set at 1.175. I'm using this on an ASUS ROG Rampage VI APEX motherboard.

For cooling, I am using a Fractal Design Celsius S36 (360mm AIO) to cool this chip in a be quiet! Dark Base Pro 900 White Edition case.

I'm curious as to why my CPU's speed keeps going up-and-down according to HWMonitor. I see it 1.2GHz while writing this, but when AIDA64 gets going, then I am at the 4.3 GHz that I am seeking.

I've attached a screenshot of what things looked like after a brief 10 minute stress test ended.

So, everything is set to manual mode for the Core Voltage and "Sync All Cores" for the frequency.

Any help to stabilize this beast, and please feel free to toss some knowledge my way. After having the same rig for 5 years I am not used to/or understand AVX and AVX512.

Thank you in advance!
