Gigabyte Aorus X570 Elite and one CMK32GX4M2Z3600C18 kit fine, two kits not so much

I'm running an AMD Ryzen 3900X, Gigabyte Aorus X570 Elite (Bios F37a) and one kit of CMK32GX4M2Z3600C18 (2*16GB) sticks was working fine but I'm facing an uphill battle when I double the RAM.

OK, so I know that the CMK32GX4M2Z3600C18 is not on the Gigabyte QVL but I've been running one set (2*16GB) successfully since March 2020 without incident, including using the XMP profile to get the full 3600 MT/s. I recently decided, as the price of RAM had fallen and I was running some more professional GIS apps which love lots of RAM headroom, to buy an identical set from Amazon and duly installed them in ranks 2/4 noticing that there was a minor version difference between the kits.

Original kit was V3.31, new kit supplied 23 months later is V3.32.

Now I knew going in I might not get the XMP profile to work but even dropping back to JEDEC speeds, my system is very unstable with Chrome crashes, random crashing on other apps and an occasional BSOD. So I'm returning the new kit as it's clearly not compatible OOTB with the built in memory profiles and I don't have the time to fiddle with settings.

If I was to go for an upgrade and repurpose my other RAM in other systems, what would you recommend?

.. to buy your RAM in a single kit of matched sticks of the capacity you want. Never mix kits even with the same PN because they could still have varying secondary timings, even if the primary ones advertised on the box are identical.

Usually they work fine at JEDEC speeds, but when enabling XMP it's blue screen heaven.

For some people it worked, but it's luck of the draw, and Corsair doesn't guarantee mixing sticks will work at the advertised speed.

If your intent is to populate all four dimm slots on the motherboard for a total of 64GB it is our recommendation, and best practice to purchase a single 64GB(4x16GB) memory kit instead of attempting to mix two 32GB(2x16GB) memory kits as neither kit is validated or guaranteed to work in a 64GB configuration. As you have discovered attempting to mix memory kits can lead to system stability issues, prevent XMP from working correctly, or even prevent the system from booting.
