2018 Hardware Thread [2]

5.1 on all cores needed a to go to 0.200 offset, and the voltage fluctuated between 1.232 & 1.248(mostly 1.248) with the Blender BMW CPU test, and didn't crash.

The temps stayed stable around 72°C until the last line and a half of rendering(last 30 seconds) and jumped to 80°C on two cores.

Not a bad btable voltage when you think I need to use 1.39V when using Manual voltage

You also set your AVX higher ...... I like to keep mine at 0
I think you use 3 ....if I remember right.....

@Cliff S have you tried setting the cache higher?

Not for these testing I set AVX to 0, as I wanted to get the highest temps for the load.
Al though I usually have it at 3.

Ok this last test for 5.2GHz, I needed to set my offset to 0.270, which is 1.312V under very heavy load in Windows.

I think I'll stop here where it's stable under a heavy CPU rendering load, as the temps are getting to close.
I had to raise to 0.270 because of a BSOD in the middle of rendering.

Here are the stats(click to pic enlarge and look at the maximum column)



Also CPU-Z


And a BIOS screenshot to show what I mean

Nice score with those volts.....I have not used Adaptive mode in a long time....maybe I'll play with it later...

Here is my score @5.0 this morning from CPU-Z

I'm not usings adaptive Mike, I'm using Offset.
Adaptive gives waaaay to much voltage on ASUS boards(wasn't a problem on my 6700Ks MSI board)

If anyone cares, my new 24/7 OC BIOS settings for now.
I got rid of the other stuff(Like all the RAM settings & timings, and the hardware settings) to make it somewhat easier.

Sorry Cliff, I ment to write Offset ....opps

Think I'll play with offset ...you got me curious

That's ok, after I read your post, I went in and tried adaptive with my offset settings, and booted back into BIOS.
It didn't do anything, Vcore is still at 1.312, which is lower than my earlier 1.39(1.40 in BIOS with LLC of 7, makes 1.39 in Windows).

I guess it's one of those settings that doesn't do anything als long as you have manual of offset selected.

But it was still worth a try, if I learned something from it

Well @5.2 its a no go for my chip .....Windows won't even take me to the desktop.....even tried increasing voltage in offset....nope.
5.1 is as high as this chip will go.
