I thought u were on 2T CL15? Guess you already changed to 1T CL16 now?
Doesn't look to bad already if that's stable.
I'll just steal 'my' (stole most if it myself  ) old 3733 4x8 config, if you got nice sticks it might work on 3800.
try this if you like:

ProcODT 36.9 (should do already)
RTT 7/3/1
CADs 24-20-20-24 (or 24-20-24-24, 24-24-24-24)
Vdimm 1.50V (you have some airflow on the ram, right?)
SOC 1.10V

left ur current settings, right the ones to try


if you don't have airflow just keep it on c16 if that's already stable. good luck.

ye ofc, gdm can only operate with even numbers. I was just expecting to see your c15 setting in the screenshot

If you have Samsung B die kit. Watch your memory temps. Once it goes above 50C , memtest will spew errors everywhere.
If you have the guts , then increase vdimm to 1.5V. push for cl14 and dont use 2T CR. In bios , CR put Auto and enable Gear Down Mode.

Vsoc put 1.1V enough, i know that once you hit 1.15V and above here , it can start to spew errors .
Vddg iod 1.05V.

Read up 🤣 thats what he was asked to set. So he done that.
You can try to raise tRFC to 280 n see if it posts.
You can use the safe boot button btw, no need to clear cmos.

Edit: @k!nex VDDG to 1.05V?  poor IMC.
for B-Dies just keep between 0.95V & 1V. Try what suits your chip.

haha dynamic or dynamicxl?

looks ... colorful  but ya very tricky one with bottom rad

Actually your current setting also good enough. 16-15-15 @3800Mhz is ok la. Sometimes its your luck also

3800Mhz, have you try put 1.5V on DRAM ?

This is confirm Samsung B die. But this one no RGB. Your rig so colourful. Might as well go buy G-Skill higher binned ones.

For stability testing.
At the timings u run you 100% have B-Dies already. Don't waste money for 1% more performance.

The problem with ram testing is that to properly test 32GB each test run would take ~4h.
So getting someone to do for you is no option if you really wanna max stuff out.
Your 3600 setting is fine, too.

Thts your CPU base clock isnt it?
