ram overclocking

[DominicNikon]

Hello, i am trying to overclock my kit of corsair dominator platinum 3466mhz cl16 on a gigabyte aorus x570 xtreme and how do these timings look? The kit is running at 3733mhz and is at 1.5V and which timings should i try to tighten more?

[Shimejii]

Honestly looks fine. Is your cpu able to run at 1866 FCLK?

For 3733MHz the primary timings look solid, though I can't really comment on the others as I'm not much into memory overclocking myself.

Can you run 1866MHz on the FCLK though?

Yes my ryzen 9 3950x easily does 1866mhz which is why the ram is 3733mhz but was unstable at 1900mhz

1.5v can be too high a voltage for certain Dies. Do you know what Die you have? I’d be putting a fan pushing airflow onto the sticks as well to stop them from overheating.

It's Samsung b-die and during stress testing the ram got up to 57c

Exactly what kit do you have? What's the part number?

That's actually pretty good.

Primary timings are not bad, and your tRFC is right in the middle of the typical 160 ~ 180ns tRFC range for Samsung B-Die.

160ns = tRFC 298 , 180ns = tRFC 336

 

Your tFAW is already on the more aggressive recommended setting.

Same with your tRRDS = 4.

You can try setting your tRRDL = 4, from 6 .... considered 'Extreme' tight timing.

Can also try and see if you are able to drop tWR = 10, but that is considered 'Extreme'.

 

Your tCWL, tRTP, tRDRD, tWRWR, tRDWR, tWRRD are all pretty damn good.

 

Definitely better than my DDR3-3000 CL14 B-Die kit.

I can do DDR4-3600 1.4V, but the timings are not as tight as yours.

Ok cool. I'm currently stress testing trrdl to 4 and twr to 10

I tried tighting the timings more based on what you suggested, i couldnt get 4 and 10 stable but i got 5 and 11 stable plus 305 trfc

Damn, that is pretty impressive.

DDR4-3733 with CL14, and THOSE timings...

Are there any timings I should try to lower even more?

Try 14-14-14-14-34-48 1T CR (2T for stability)

Loosen the Trfc a little bit.

So these are my timings at 3766mhz i've been running stable for 24/7 and 2000% mem test. how do they look?

[Guest]

That'll do! Fast and tight. Nice work
