Ryzen Memory + Fabric OCing

[xBlizzDevious]

Got a new 5950X with some 4000MHZ CL16 GSkill Trident Z RAM. I can get the RAM to run at up to 3800MHz and I can get the fabric clock to run at up to 1800MHz.

If I try and take the RAM beyond 3800, I get a few attempts to restart and then it errors and boots in safe mode, asking me to update the config.
If I try and take the fabric click beyond 1800, the computer tries to boot, shows an error on the RAM POST LED on my motherboard (Asus STRIX X570-e Gaming) and then stays in that state indefinitely., requiring a CMOS reset.

I haven't and don't know what voltages to increase (if you can) to try and push further and get a stable system at the rated RAM speeds. Which ones do I need to to tweak and what are safe-ish parameters?

Any other OC tips for this platform as my familiarity is first gen Core i7 and X79 (3930k) OCing.

lower and 3733, i think it was to run it 1:1, higher and you will go into 2:1? for ryzen's infinity fabric.

is it worth to go higher in your case?

else: (not about the issues your having but some about the ram)

If you manually specify the fabric and memory clock, I thought you continued to get the 1:1 ratio?

1:1 refers to memory controller and memory. Not infinity fabric which you should still keep as half the memory speed. You can try raise VDDP to say, 1.05V to try help with IF frequency but no guarantees

You would probably be better off just running 1:1 and tighten your timings as much as you can.

I'm intending on running 1:1. I didn't explicitly say it in the OP but when I said I can't push either the memory or the fabric clock up, my end-goal is 4000MHz RAM (2000MHz actual speed) along with a 2000MHz fabric clock. Is there something else I need to keep at the same rate or is that everything?
