I testing Samsung 8192 MB (DDR4-2137) - P/N: M378A1K43BB1-CPB

now up to 3600 CL17-19-19-19-39 TR2 1.4V set in bios

but

CPU-Z show 18-19-19-19-39 TR1

Any idea why bios and CPU-z show different value ?

Check and see if Gear Down Mode is On in BIOS. If it is, then it will auto correct CAS to an even number.

Before you do, run a benchmark like Cinebench 20 or Aida Mem Latency test and compare. Doubt there will be a diff.

Yes I noticed now gear down mode on switching to off and need adjust to Cl18 because Cl17 is not stable

Going for 17 might need a bit more vcore. Some have no qualms using 1.5V on DDR4 but 1.45v is safe.
