i've yet to bench stable on 3600 on 8x2 kits with really relaxed timings

so i forced my kits with the only stable speed and work my way down on the timings till i reach cl 14 3466

16GB per stick is still challenging for Ryzens but still...

I have no ASRock mobos with me right now but what the guys are ssying is true.

The goal is to try and replicate the timings manually in BIOS, with only the speed is left at 2933.

If XMP won't put the higher voltage you should put it yourself. Also, bumping the SoC voltage a notch up is doing wonders.

If possible, read the RAM model with a program of ypur choice. Let's make sure you got the right stuff you intended to buy. Then run Ryzen Mem Calculator and post back the values it suggests.



Thanks again. OK - examined RAM with Thaiphoon Burner and imported them into DRAM Calculator. I've attached the results.

One thing I do notice from the typhoon report is a top freq of 1067MHz?? Also, the "JDEC DIMM Label" is "16GB 2Rx8 PC4-2133-UB1-10" - implying a top speed of 2133?? I'm not very knowledgable about these things so most likely wrong!

Would appreciate any advice going forward.

1067 is the max jedec in it the xmp is the one below it you should export the typhoon settings and import it to RDC if the R-XMP function in RDC doesn't work

OK - but I that's exactly what I did.

It's getting a little off topic - with the results above, what do I do next to get 2933?

I really have no clue what the BIOS layout is, but the idea is simple.

You should try and put those 15-15-15-etc. timings in your memory settings in BIOS. Then put 2933 for speed. Basically, we want the XMP settings but with speed dropped to 2933 instead of 3200.

For now I want to run the sticks at 2933 with the default timings. As it's evident by now that you're out of luck for auto (fire-and-forget) settings, we can try tighter timings later on.

Can you please try and dig any BIOS page that looks memory-related and poat it here? Without any clue of your BIOS layout you'll need to be our eyea.
