Damn! Your RAM is clocking well! I guess you are running 2 sticks?I guess the only fear I had about swapping in the 5900x as the FCLK potential. I haven't tried anything higher yet, but at least I'm good to go at 4000MHz still. I just swapped it in this AM so I haven't really had too much time to play around with it yet. After playing around for a while I'm going to do a fresh install of Windows....Some say it's not a requirement, but I'm one of those just in case end users!

There was a little bit of a latency penalty compared to the 5600x, but I think I can live with it.

Yep! and yes I'm only running 2 sticks. I'm thinking my kit was produced during the crazy high DDR4 pricing and wasn't really binned well, if at all....I wouldn't minDamn! Your RAM is clocking well! I guess you are running 2 sticks?
I made my set of Samsung B-Die stable at 3840MHz CL18-17-16 and the rest of subtimings tweaked, but my best latency was 56.8ns and 56GB/s Read.

Can your kit do 3600 CL14? With tight timings you could shave off a couple ns's and not lose any bandwidth....Viewing my 3600 CL14 snip a couple posts above for reference.
What kit do you have? The dual rank 32GB one?
4000MHz takes 1.5v's on my kit. I have the Corsair iCUE 220T case with 2 140mm's up top as exhaust. They're cooling my memory and VRM heatsinks.G.Skill Tident Z RGB F4-3600C16D-16GTZR
At least in 4 DIMM configuration, my kit fails at 3600 CL14, it will do 3333 CL14 with 1.4V. I need to try it with only 2 DIMMS at some point, but 3820MHz CL18-17-16 is not bad, considering it's 4 sticks. Tonight, I've tried pushing 3866MHz and it failed miserably , not detecting CPU, so I guess IF had enough at 1933MHz. Now I'm struggling to get back to my stable 3820MHz, heck even XMP 3600 CL16 was giving me memory errors. Need to clear BIOS and start from scratch me thinks!
EDIT: forgot to mention that I never tried more than 1.45V on my memory, maybe it's time to give em some volts? Just need to place a fan blowing on DIMM's as there is no air-flow there due to Water Cooling.
I have 9 fans in my case, but Thermaltake Core X9 is soooo freaking huge, that there is virtually no air moving around RAM and VRM's4000MHz takes 1.5v's on my kit. I have the Corsair iCUE 220T case with 2 140mm's up top as exhaust. They're cooling my memory and VRM heatsinks.
I use the MB's overclock profiles for different memory clocks. Quick and easy to switch or restore them when I tinker around.
I just need to score a reference 6800 (XT) and I'll be set. They're the largest that will fit as my AIO is front mounted. Reference 5700 in there now with maybe 3/4" of clearance.
