Question RAM Mismatch!

I recently bought two sticks of CORSAIR VENGEANCE 8MB LX RAM from two different vendors, they are exactly the same model, but one shows as SAMSUNG in CPUz the other as MICRON, subsequently they are not running in DUAL CHANNEL. Any suggestions? My machine is running poorly because of it. Have a GIGABYTE AORUS PRO B450 RYZEN 3600

AFAIK, Corsair (nor any other vendor) make any definitive promise about the specific chips used in memory modules. You'll note the product numbers (within serial numbers) will be slightly different.

This is why a retail 'kit' (2x8GB), sold together in retail packaging is always recommended - Some RAM, even the same 'model' won't always play nice with A.N.other module.

Regardless, mismatched RAM should be capable of dual channel - just at the lowest common denominator in terms of speed/timings, but there's no guarantee that'll work without a hitch.

return them and get a 2x8GB kit
Seconded.

There aren't any "suggestions" possible. The bottom line is, buying memory separately results in exactly what you have, different memory. It doesn't matter if it's the same part or model number not. If you want a guarantee of compatibility then return or sell the sticks you have and buy ONE kit with all the sticks in it you need. THAT is the only way you'll get any guarantee of compatibility with each other.

See here for an example of three different memory configurations that all use the same model number at various points in production history.

Even with IDENTICAL model or part numbers, there can and often ARE differences. If they did not come from the same production run, were not tested together to be stable at the same speed, timings and voltage, and validated for a given motherboard, then all you are left with is the possibility, not the guarantee, that they will work either together or on any given motherboard. Or with any particular CPU for that matter, since the memory controller is often a factor as well and some are just simply stronger than others.
