You have a 2x8 16gb Corsair Vengeance RGB Pro with 3600mhz CAS latency 18-22-22-42 and 1.35v. The question is whether you can use the same setup (same kit, same speed) but with different CAS latencies (16-19-19-36). You're wondering if it's feasible to overclock your current rig to match these timings or if it's more complicated. Would it be possible to run both kits at CL17, or in the worst case, have them both running at C18? Thanks in advance for your help.

it is never advised to combine sets of RAM, even if they match the same model.
you might not be sure they will work together at the same speeds and timing.
even if they function without causing crashes or errors, small variations in their performance characteristics can still affect efficiency.

Combining several RAM kits isn't assured. It could succeed. It might not work at all.
You'll need to set them to the maximum latency (CAS18).
It might be required to lower the frequency to 3200mhz or 2933mhz, to keep things stable.

That's what I was considering, I have some ideas but I'll double-check for any issues with memtest. Thanks

Yes, I made a significant error on my end, but I didn't realize this 3600mhz kit for CL16 was available. I bought it without doing proper research. I'm based in Ireland and ordered from the UK, which means dealing with the return process after Brexit is quite complicated. Thanks.
