The AMD Ryzen All In One Thread /Overclocking/Memory Speeds & Timings/Tweaking/Cooling Part 2

Zen+ imc isnt going to let you get stable 3600 and it will probably crash in games. Mine also does not like it so keep it on 3200.

 

^^ Or just set up Stable 3466 or 3500
I know it works.... 2700X will have it NP.

Maby You know why i have freeze when trying to Validate with CPUz ?
Black screen, and need to hard reset.

Can it be related to High precision Timer?
and this:
bcdedit /set useplatformclock false
bcdedit /set disabledynamictick yes

 

Setting tRC manually to 56 didn't do anything awesome xD

Went up from 73.3 to 73.4

Spoiler

Memory read went up a little bit, from 45551mb's to 46107mb's

Spoiler

I am noob... ayyy

 

Depends on your chip. Even with dram 1.45v and 1.15v soc i cant even get 3466mhz completely stable. In some games it will crash even though passes the memtest. Maybe becouse i have 2x16gb dual rank kit.

 

Why is my memory write speed half the speed of Grimbarian's? is it to do with the chipset or the memory modules themselves?

 

Single ccd its normal for zen2 besides 3900x which have two.

Thanks, I was thinking something was going wrong.

 

Memtest ran solidly for 40 mins with 16 cores and no errors, then when I came back from lunch it had crashed:



And also coincidentally (or not) I was seeing reports of hard drive errors:



Every hard drive, exact same timestamp as the Memtest crash, anyone any thoughts what that could mean?

 

Yeah IIRC 3200 is already classed as "overclocked" on this board so always knew 3600 was going to be a push, maybe lower speed with tighter timings is the way to go? Just a shame that's not as easy as bdie + DRAM Calculator for Dryzen.

 

Also had few hours without an error in memtest and then i went to test some games Mafia remaster crashed in a few minutes so no go. Calculator also didnt work for me i wanted to manually tight up timings but then i realized i had to disable gear down to use some odd timings. Meh, stock cl16 3200 is fine enough i kinda gived up for now. Stability first.

 

40 minutes of memtest is nothing, you want 40 hours.

 

Yeah I know, just wanted to see if anyone had an idea why I got the app+ hard drive errors at the exact same time...

 

Interesting comparison.

seems mine is all over the place compared to yours.

 

Definitely interesting comparing results.

 

here is my garbage 3600 C18 with the stock XMP settings

 

My best results ( that are 100% stable , not for CPUz trolling ).

Anyone can tell me which timings i can improve and which affect latency most ? .
i can do CL14 ( cant do 15 , its buged , if i set 15 it goes 16. ....) but it almost changes nothing and i have to push extra volts.

Is there anyway to change clock with Ryzen master to be permament ? I Can set 4850mhz all core in Ryzen master , but i can't even boot if i change multi to 47x in BIOS ....

 

Its not bugged you have gear down enabled. Disable it and then you can set cl15/14.

 

Well i can select CL14 with geardown , just not CL 15 So kinda buged. Without geardown i run in all kind instablity problems

 

100.28 Bclk
PBO+200
Scalar x10
PPT=200
TDC=105
EDC=215
Curve Optimizer enabled, each core adjusted to lowest possible without crashes or errors.

Holds 5060 in single core 1.48v, Effective shows 5048 or 5015, Max temp single core is 53.8
Holds 4.785 in multi with 1.33v, Effective shows 4.695. Max CPU temp 67.6, I usually see 71-73c after radiators are heat soaked for multi.

Think I'll hold off to tweak further until new Agesa.
