I have two 16GB Corsair Vengeance DDR5 sticks rated for 6000 MT/s, CL36, with the same timings and voltage. Their version numbers differ: 3.43.04 and 4.43.16. Is that likely to cause compatibility problems?
Will two versions of the same Corsair Vengeance DDR5 RAM work together?

They may work together just fine, even with the XMP profile enabled, but matching specs aren't a guarantee. Try them at the default memory settings first, then enable the profile and test for stability. If you get crashes or boot failures, you may need to run them slower.

The version difference can indicate different memory chips or revisions under the heat spreader. Two sticks can have identical advertised speed, timings and voltage but still behave differently, especially when running an XMP or EXPO profile.
A matched kit is the safer choice if you want the best chance of the rated settings working without troubleshooting. Separate sticks aren't tested together as a pair, so there is some uncertainty here.

I wouldn't assume a version mismatch means trouble. The labels match on the main settings, which gives you a reasonable starting point. Just keep in mind that the opposite is also true: matching labels don't prove the pair will be stable.

Passing a boot test alone isn't enough. Run a memory stability test as well and watch for errors.
