Need help with overclocking 4 x 16GB of b-die past 3600MHz on 5950X

[TwilightRavens]

So as the title says I've been having a bit of trouble trying to stabilize an overclock of my RAM and was wondering if anyone could suggest anything I can try. Memtest errors within 5% into the test

 

Specs:

AsRock X570 Taichi Bios 4.80 (I am aware that the memory topology of this board is Daisy Chain and is geared towards 2 sticks of RAM, but I have heard it should still be able to hit 3800MHz)

Ryzen 9 5950X

4 x 16GB G.Skill TridentZ Neo 3600MHz C16 (Dual Rank b-die) I am also aware they are different batch dates but I have validated them separately in 2 x 16 sets and they can hit 3800MHz)

 

I've also tried:

SoC up to 1.2v

VDDP up to 1.1v

VDDG IOD and CCD up to 1.12v

and none of those were able to affect anything, and am I missing any voltages that I should be adjusting?

Any reason you want to do this? Youd be going over the blck clock of the 5950x and that would lead to no performance improvement due to it (can even perform worse). Did you oc your memory controller too? This can also help achieve your goals.

You have to do that with every stick against every other stick, not just the set they came in; label them 1 to 4 and "validate" the following pairs:

1&2

1&3

1&4

2&3

2&4

3&4

fclk is synced to the memory frequency, so 1867 with 3733MHz RAM, and have validated stable fclk with 2 sticks at 2000Mhz (DDR4 4000).

Oh right, I forgot about that part for signaling quality on the motherboard, better sticks in the worse slots and bad ones in the good slots.

The other pairing was unsuccessful? @Ralphred has good advice here. Can be as simple as switching around the pairings to get a successful oc.

Signature says 1.5v. Is this the XMP voltage, or did you need that much for just 3600mhz? The later, try more.

 

Timings used? It's just a guessing game for people to help.

 

Validating sticks is a joke. You're overclocking them all together, it won't matter which stick is which slot. You already know 2 sticks is where the performance is at. You'll beat on the system to accomplish a mere 100mhz effective clock (ddr 200mhz) and probably no difference in performance even if you where to benchmark it all day.

 

Good luck!

I think it's your motherboard. AsRock kind of sucks. I would stick with MSI or ASUS in future builds if I were you. AsRock bios support is really bad. They boards look nice and the specs are good but they lack the bios support to make things work well in my opinion. I have dual rank Micron E-die running @ 3800mhz on my signature board. I have a B350 running 3800mhz on an MSI with a 3600mhz with no issues with the latest AGESA bios. Before, my B350 would only run 3600mhz stable.

I’ll post a ZenTimings screenshot next time i’m at my computer. XMP calls for 1.35v, and the main timings are 16-16-16-16-36 was running 1.5v from when I was running 2 sticks at 3800 C14.
