I'm trying to optimize my Corsair Vengeance stable (subject build). I managed to stress test it at 3000mhz, but still encountered random BSODs, so I've moved it down to 2933 and am currently testing. Any advice would be appreciated!
The main issue is: Why can't I set the CAS Latency to 15? I've used both Ryzen Master Tool and BIOS settings, but when I switch to Windows, the CPU-Z shows 16 for CAS Latency.

Can I still set it to 15?
A side note: I've struggled to consistently enable my (only) XMP profile, which often triggers BSODs. The most reliable approach has been adjusting the frequency and timings in Ryzen Master Utility.

I've seen some reports suggesting Ryzen systems handle odd numbers of cycles by rounding them up.

For Ryzen only even CAS latencies are available above the highest AMD standard of 2666 MHz. Choose c16, or attempt C14 if needed.
