Hey!
Two years ago i bought Patriot Viper 4 Blackout 16GB (2x8GB) DDR4 3600MHz PVB416G360C7K (CL17) rams, and now i want to get two more, but its discontinued in every online store. There are only CL16 and CL18 versions availbale.
What can i do now? Is it possible to mix rams with different latency or do i have to re-buy different ones? Would appreciate the help!​

Please don't mix and match rams. You should either look for the same ram kit as you have now or you go for a higher capacity ram kit from any brand you access to, i.e, a 2x16GB DDR4-3600Mhz ram kit.

What is the make and model of your motherboard and processor? BIOS version for your motherboard?

I would go for the same ones but they aren't available anywhere.
I have a ryzen5 5600G cpu and an ASRock B450M Pro4 motherbaord (American Megatrends P5.30, 2021.08.04.)

Yes, you can mix DIMMs with different latencies, although you cannot guarantee stability in all cases.

Some people advise buying four DIMMs as a single kit, not two "identical" pairs. Even when you buy two pairs with exactly the same part number, there's no guarantee the memory chips and sub-timings will be exactly the same. Mixing two kits with completely different part numbers just increases the risk.

Depending on how your motherboard interrogates the SPD chip on each DIMM, it may pick a set of timings which are marginally "too fast" for the slowest pair, on the assumption you've fitted four identical DIMMs.

Or it could run the DIMMs with the timings of the slowest pair, which will be a better solution.

The only way to find out is fit two (dissimilar) pairs and check the actual timings set by the BIOS. Then swap the pairs over in the mobo and check to see if the timings have changed. Choose the slower CL18 timings in preference to the faster CL16 settings, if your original pair are CL17.

A much better solution would be to ditch the old 2 x 8GB and fit 2 x 16GB or 2 x 32GB. Two DIMMs are usually more stable than four DIMMs made up from two unmatched pairs.
