Hi

 

I wonder what is a reasonable fast and stable speed for CPU cache for this CPU? 

 

Today I have set it to 4300 MHz. 

 

I want my system to be fast but not comprising stability. 

 

CPU 9900K Clocked at 4900 MHz on all cores avx offset set to - 2

My ram is 4 x Gskill 3200 CL 14 16GB

Motherboard Asus ROG Maximus XI Hero

Powersuply Corsair HX 1200i

CPU Cache overclocking has almost zero impact on real world performance, honestly it doesn't matter what speed you run it at. It's something you should only care about if you're doing XOC.

Main Rig:-

Ryzen 7 3800X | Asus ROG Strix X570-F Gaming | 16GB Team Group Dark Pro 3600Mhz | Corsair MP600 1TB PCIe Gen 4 | Sapphire 5700 XT Pulse | Corsair H115i Platinum | WD Black 1TB | WD Green 4TB | EVGA SuperNOVA G3 650W | Asus TUF GT501 | Samsung C27HG70 1440p 144hz HDR FreeSync 2 | Ubuntu 20.04.2 LTS |

Do run alot of virtual machines tought it would help. So if it does not help to overclock it should leave it at stock speed? Does overclocking the CPU Cahe increase the heat alot?

Your CPU Cache frequency should be no greater than your all cores turbo boost clock in the 9900K's case that would be 4.7ghz.... beyond that you are very certain to suffer instability.

I run all my cores at 4.9 GHz, so you recommend to run my CPU Cache speed at 4.7 or less. If did understand you correctly?
