Are my Memory Sub Timings ok?

SVSQUVSH · Feb 23, 2023

I recently upgraded to a Ryzen 5 2600x and bought this Ram Kit: pv416g320c6k
It's 3200mt's cl16, 18, 18, 18, 36 1.35v

First of all, on my MSI B450-A Pro Max when I used the best XMP Profile, it gave me completely different Timings. It was cl16, 20, 20, 20, 54 on 3200mt's.
So I decided to disable XMP and manually set the Ram to the rated speed and timings.

I am wondering now if my sub timings are also bad, because of the fact my Ram didn't apply the right XMP profile...
Currently I'm running on the XMP Sub Timings and I set the Ram Speed/Primary Timings manually.
(Sorry if something is unclear for you, im a total Memory OC Noob ^^)

Maybe someone can tell me if something is weird or what I can change on the Sub Timings.

Here are my settings:

They are better than they were before..
tFAW shold be 20 (tRRDS x4)
tRRDL try 7 or even lower - can go to 4 even best case
tRRDS try lower to 4 - if good tFAW shold be 16 (tRRDS x4)
tWTRL 12 or lower
tWR - 24 should work
Lower tRFC as far as it start to give errors - after that go to higher number so its stable - go in steps of 40 or 20..

Hey men, thank you for your reply. Based on your suggestion, I changed those values step by step and it actually made a difference. tRFC is still relatively high (I set it to 540, just to be safe, because last time followed a guide, I set it to ~500 and my ram spit out errors). I ran 2+ hours OCCT AVX2 Large CPU benchmark (you think ~2 hours is enough?), and ZERO errors. In the Membench that comes with Ryzen Dram Calculator I get 9 Second reduction. From 141 to 132 consistantly. In games it boosted the 0.1% and 1% low FPS quiet heavily.
Thanks for your help. If I have the time, I gonna reduce the timings a bit further, most likely tRFC.
But I'm quiet happy with the results!

Can you please grab:
~ rename to .zip

Run it with admin permission, and show the result after ~2 hours ?
If there are errors, please screenshot them - the amount and when they come are important

Also can you check if this runs, and displays timings

You are looking for WPRE & RPRE
tRDWR = ((CL-CWL) + BurstChop [4] + 1 + WPRE)
~ credits PJVol

Your result expects WPRE to be 2.
Please verify , if this new versions opens for you.

Should be on Timings Category 2 or 3
If WPRE is 1, then correct your 9 to an 8 on tRDWR

For your Board you might also try CAD_BUS: 24-20-24-24
& generally SCL's at 4-4

EDIT:
At the very end you should try to put a 1 (if not possible a 2) on SD's and only keep DD's as 5 & 7, for a 2x8gb setup
