5950x OC all core

faceman123 · 9 Sep 2021 at 18:25

Hey so every google search results in me getting a different answer,

I'm getting 29.5k Cinebench @ 4.525ghz @ 1.21v

Is this a low score, and my temps are 80C under full load on an NHD15. Tempted to go Custom loop. Now i also have a B550 which i'm not sure maybe limiting me

4.9ghz seems to be do-able, but red teamers should confirm.

mid just leave it lie that, not much more to be gained. I can do 4.7ghz all core on mine but it requires 1.29v, I haven't tried any higher voltage to see if it can get faster - I get 78c with this on water

what sort of volts and temps do you get if you do something like all core 4ghz or 4.2ghz?

at 4ghz he's should need close to 1v flat since that's what a stock 5950x does - if I set mine to stock and run cinebench I get 3.9ghz all core with 1.0v

What sort if temps do you get with running it at 1v and what sort of power consumption does it show in something like hwinfo?

Thanks for this - Yeah i'll keep it as - on a side note was taken aback how much the gain is vs stock ( pbo off )

Mine wii pass CB with 1.096v under load @ 4.6Ghz. Peak package power 168W, temps 53.3C.

Damn that's crazy good, must be a golden sample

I thought all core overclocks for the 5950x were a bad idea, especially 24/7.

nope, I've just infact managed 4.525GHZ @ 1.18v @ 73c Cinebench 10min run under an NHD15 - Runs smooth as milk 29700 Score

You usually end up sacrificing single core performance. Better off using PBO with curve optimiser.

Ahh nice 1.18v seems pretty decent.

I thought it was more towards it is not safe for the voltage.

As long as you uses sensible voltages I don't think it's terrible.

No, this is incorrect, it is due to loss of single core perf.

I never really understood this idea. By the looks of it almost everyone who does an all core oc ends up using a lower voltage than pbo does

Yeah i am not 100% sure either, just something i keep seeing pop up when i do any research in to it.

I think originally people were seeing Zen 2/3 use 1.4V ish so assumed this was OK to use for all core OCs. The reality is is that Zen only uses those high voltages transiently and under low loads.

A conservative voltage all core clock isn't a problem but you lose some of the single core/few core performance as you no longer see the high boost clocks you'd get with PBO.

In the bios under "Amd Overclocking -> Manual Overclocking" part of the bios where it asks for voltage and core i am assuming 1200 = 1.2 - 1180 = 1.18 & 4500 = 4.5 etc as it does not specify what parameters it uses. Don't want to end up blasting it with volts.

Sounds right but I'd double check YouTube pc guides for your board
