Got a decent score, but there's room for improvement, since I had better runs.

Spent a whole evening trying to get 4066 running reliably, but it seems my CPU can't handle it for some reason.

The better 2x16 kit just doesn't want to run GDM off, so opted for an old 2x8 A0 kit.

PS: Top 3 scores are all in our team :p I guess the internal mini-competition helps.

Hello everyone
I would like to challenge the 5G challenge with 5600X and C8I.
First of all it is difficult to set the CPU to 5G
At present, it will drop even at a voltage of 1.5v at 4.9G.
AMD has little experience so I would like to ask professionals for advice.
Is PBO setting important?
Where do I need to set it in the BIOS?

Posted

no, PBO for benchamrking no needed. PBO is for daily type of cooling and 24/7 (optimized with curve optimizer)

 

But for 32M U will need disable the cores and hyperthreading and push CPU to 5 GHz (propably best way boot on lower clocks and set higher value in OS)

And of course, a lot playing with DRAM timings and IMC (SOC voltage etc) :)

Okay
SMT is OFF only for 3 cores
Set to 4.8G on BIOS
Voltage starts automatically
In TurboV Core, the voltage at this time is 1.4V
Memory applies only XMP and does nothing
Is it simply a low voltage to raise it to 5G?
Is there any control working?

RAM tweaking is about learning...First, boot at example 4.6-4.7 GHz with manual voltage (1.35-1.375V) and LLC3.

In WIndows u can increase the CPU voltage on 1.4V and try go to 4.9 GHz, if failed, or frozed, restart and in Widnows use higher COU voltage...For 5GHz maybe u will need up to 1.5V, but all depends also on temps, silicon lotery etc. After u will know, your CPU is able run Superpi with JEDEC RAM settings, u can continue in RAM and SOC tweaking (FCLK 1:1 with RAM and fun with RAM timing and driving)

It is not job for  few minutes, but for few hours and maybe for few days.

I ran SuperPI 32M for the time being
The CPU runs up to 4.9G, but after that, even if the voltage is 1.5V or more
Will fall
I'm at a loss what's wrong
Simply my CPU no limit? Set LLC to 3 and disable SMT on the BIOS
C state disabled 3 core selection only
I would appreciate any advice

well done (propably u have not best sample...) Good samples are able run CinebenchR15/R20 at 4850-4900 MHz on AIO cooling

The limit of the CPU I own ...
Personally, I want to study ZEN3 a little more
There is a mysterious part in the BIOS settings
  I want to know the basic settings for Zen SuperPI 32M
Isn't the adjustment of Curve Optimizer related?

Posted

@GTI-R I think basically any Zen3 CPU should be able to get through SuperPi 32M with 1.45V Vcore - just make sure your LLC is set to the middle setting. Leave memory settings at plain XMP until you get the CPU overclock dialled in right.
