Most likely an unstable over clock

pstates are used in graphics cards and now also ryzen uses them. thats what gives you the gpuboost technology and whatever amds is called. if you've done gpu bios modding, you know pstates

the values arent obscure, the mobo makers just haven't had time to give them user friendly names and values.

the powah of Ryzen in NLE rendering, still got like 30% usage left over to play a game or something lol. 7700k can't touch this.

Could someone point me to a good tut or guide that explains Pstate overclocking?

The things I saw earlier didn't make sense to me. Got my system to post and boot Windows at 4.0 @ 1.35-1.375 vcore. Wouldn't pass any stress testing but could do everything else in Windows (didn't try Gaming). Yet when I backed it off to 3.9 at the same it wouldn't even boot into Windows.

At this point I've completely reset to stock as I finish getting all my stuff installed and do some poking around on the net. I want to get a stable CPU OC before I start messing with the Ram.

All you really need to know for Ryzen is how to set the first one.

Here's how it works and how I did it on my C6H:

CPU Ratio = 0.25FID/(DID0.125)
Core Voltage = 1.55-0.00625*VID (will only apply if you use Auto or Offset Mode for vcore)

On the C6H, you enter the values in Hex.

Say you want to do 3.9GHz, FID would be 156 or 9C in Hex. 3.8GHz is 152 or 98 in hex and 4GHz is 160 or A0.
For 1.35V, it's VID = 32 (1.55-0.00625*32 = 1.35V), which is 20 in hex.

Aida Bandwidth doesn't represent what these chips are capable of yet. At least Memory Latency makes sense now.

makes sense in good term or bad?.. it's been long time i havent playing around pc things redface.gif

Makes a lot of improvement?
Makes sense? tongue.gif
post #6619 of 11493
in some benchmarks its can yes. Just need to be smart enough to know where and when not to use it as a tweak smile.gif

Aida i'm unsure but it might work.
post #6620 of 11493
I haven't been benching it cause yeah, they can easily make me eat dust. biggrin.gif

I tested different configs to come up with a Quad Core. Almost the same perf numbers from Aida using 2+2 and 4+0. thumb.gif
