DDR5 Micron 16 Gbit Rev A (5M16A)
Micron’s 16 Gbit A-Die has been the worst choice in terms of performance and clock potential since the early days of DDR5. These ICs are also only available in entry-level kits up to DDR5-5400, simply because they cannot be run faster. However, the “ugly duckling” of DDR5 should not be missing in our tests and will show that a newer standard is not automatically better, especially in comparison with good DDR4.
For reference, we use a Fury Beast kit from Kingston with XMP profile at 5200 Mbps and timings 40-40-40-80 at 1.25 V.
We also overclocked this rather modest DDR5 IC again. Meanwhile, up to 6000 Mbps can sometimes be stabilized on the Z790 Hero, but unfortunately the behavior is not consistent from training to training, so DDR5-5600 is the highest reliable setting. Optimizations are rarely made for the rather unpopular DDR5 dies, even on the part of the motherboard manufacturers, which might explain the still bitchy behavior. At least a tRP of 24 and tightened subtimings can still elicit a bit of performance reserves from the kit.
