Core I7 7960x Overclock - What is Cache Max Voltage?

[NicklasAPJ]

Hello, IM just startede to overclock my 7960x, and quick im on 4.6Ghz, but before I go any higher, I want to find the cache max clock. I just cant find the stock voltage for that? and anybody know what max should be for that on Skylake - X.

 

Thanks.

i have researched and it would seem 3000-3200 is typical, but cant find what voltage. i would try 1.2-1.25 and see if it catches fire. if it does i guess it should be ok.

@done12many2 you should know this

Aleast I laugh.

 

ye, will just try a bit at a time, and we see. trying to beat a TR 1950X 5.1Ghz on LN2 @ 41xx CB with this for fun, should be doable.

 

Thanks.

What kind of temps are you getting at 4.6GHz because even without a mesh overclock, you might be pretty toasty without a delid?  I believe stock mesh voltage is around 0.9-0.95V. If you want to overclock the mesh, I would probably go to 3200MHz at 1.15V max to be safe.

4.7Ghz around 59c in benchmarks like Firestirke/timespy CPU test. Did not test in Cinebench yet.

The CPU is not delied.

I would test the temps in something like Prime95 or Blender to get a better representation of the temps of your overclock.

Im not running that 24/7, is only for becnhmark purpose, so no point

 

At 24/7

 

im running 12 Cores at 4.1Ghz, and 6 at 4.5Ghz.

The reason for testing those more stressful tests is to make sure your overclock is fully stable, so you don’t get random crashes when you least suspect it. Perhaps you will need peak performance for a couple of moments and if your overclock isn’t 100% stable, it will crash on you without reason. Anyways, your overclock sounds pretty modest so you should be fine.

4.7Ghz/3.1Ghz on Cache Cinebench Score and TEMSP.

Tbh faster than a 5.1Ghz 1950X on LN2.

 

67c on the hotteste core under a Cinebench run.
