Thats better!
But... Considering the high quality of your sticks (B-dies on a 10-layer PCB) with a rated speed of 3600 with 16-16-16-32-54 you can do alot better than this
Take a look of mine with lower quality sticks (B-die 8-layer PCB)
This is with 1.45V DRAM voltage:
Imagine what you can do with your sticks
First you need to run "AIDA64 Benchmark" to have a baseline of scores before tweaking anything.
Second I suggest to go into BIOS and set CLDO VDDG voltage lower than the 1.1V that it is now. Not only its too high (unnecessary) but also is higher than VSOC which is false.
CLDO VDDP/VDDG voltage must always be lower than VSOC.
A good start for further OC is:
DRAM voltage: 1.45V
VSOC: 1.08~1.10V (1080~1100mV)
VDDP: 0.90~0.95V (900~950mV)
VDDG: 0.95~1.00V (950~1000mV)
You can benefit a lot your RAM scores (mostly latency) by lowering tRFC (under 400) and by raising speed.
Of course other timings too, but a few at a time...
After you run the AIDA64 benchmark I would raise speed to 3733~3800 (and FCLK to 1866~1900) and set UCLK==MEMCLK.
DRAMcalculator has a build-in MEMbench for stability and error detection.
Keep "GearDownMode" Enabled and "PowerDownMode" Disabled
Some optimal primary timings would be
16-16-16-16-32-48
16-16-16-16-34-50
16-16-16-16-36-54
I bet your sticks can do 14s but try first to raise speed before tight timings.
tFAW must always be x4~6 to tRRDS
Any questions, happy to answer.
