B Die oc on Cezanne

[superpatodonaldo]

Hi to all

I'd like to improve BDie oc on Cezanne, please someone can suggest voltages and timings to set? I am on air, maybe cold in future, I guess.

I think it is a little bit different from intel platforms.

Thank you very much in advance

any help?

about voltages:

VSOC max 1,25v on air / H2O ?

VCPU max 1,25v on air / H2O?

VDRAM ?

other voltages or volt's range?

mem timings? 

thanks in advance

hey mate, what board and CPU are you on. And what benchmark you shooting for as that will determine if you want coupled mode or high freq.

Thank you for reply

5600G/5700G on ROG B550-E

Bdie A0 and I'm waiting for a 3800c14 neo

Basically like to improve cinebenchs, geeks, gpupi, x265

bump...

no input?

I see some zen timings tab pics, but need to know voltages' limit (don't like to kill cpu or ram chip)

Sorry, yeah so you want to stay 1:1 fabric and memory. 

Safe or not I'm not sure but on air I have used 1.45vcore and 1.45vsoc. dram 1.92-1.96 for 4800 14-14

Sounds like your voltage just needs to be increased.

thank you very much, yes, I am testing around VSOC 1,25v and VDRAM max 1,7v

4800c14 or similar need maxmem?

secondary and tertiary subtimings AUTO or manually settings?

I found it really easy to clock, much easier than messing around with IO/SA on Intel.

Set Vdimm that your sticks like (test on other platform maybe), make sure the CPU stays cool (so don't set like 1.5V+ vcore), active cooling on the RAM. With just this I was able to get 4200 12-11-11-10 1T gear 1 stable ? Maybe a small bump for Vsoc is necessary but that's chip-dependent.
