[M] Crucial 32GB (2 x 16GB) DDR5-5200 Memory Kit Review
 

The new 5200MHz memory modules from Crucial are a great improvement in terms of overclocking versus their 4800MHz counterparts we have tested before, being able to reach 5800MHz without too much of a hassle, just by increasing the stock voltage to 1.25 and keeping the timings as the manufacturer intended. For compatibility sakes, we are also getting a 4800MHz XMP profile, while AMD users would be happy to know that these feature an EXPO profile as well!
