1600AF Low frequency problem

[Darudevy]

Hi, I'm having issues with my 1600AF. When i benchmark with Cinebench 23 and 20. frequency dont go above 3.2ghz. And because of that i get lower results than stock 1600af. While gaming it dont go above 3.4ghz. I think the temperatures are normal. Does not exceed 65 degrees under load Where is the problem? What should i do about it? Thanks.

 

Motherboard: B450M S2H

Ram: 8*2 3000MHz HyperX Dual

Seems it's working fine.

Base clock is 3.2GHz and turbo is 3.6GHz.

Turbo is only for single core and you're getting 3.4GHz at medium load which is 200MHz above base clock.

Yes, but shouldn't it be 3.4ghz in the cinebench test? Also It didn't exceed 3.2ghz when I tested it with Prime 95.

If you can tinker with PBO you can increase the PPT.

And that is the issue. There are no options related to pbo in mobo. I installed the latest bios but nothing changed.

Then there is not much you can do. But the CPU is running correctly.
