Frequently asked
Is Crucial CT32G4RFD4293.36FE2 the same module as MTA36ASF4G72PZ-2G9?
Yes. Crucial resells this Micron module under part number CT32G4RFD4293.36FE2. The physical module is identical: OEM part numbers are branding, not different hardware.
Can I use a Micron or Samsung module instead?
In most servers, yes: MTA36ASF4G72PZ-2G9E2 (Micron), MTA36ASF4G72PZ-2G9E2TI (Micron), MTA36ASF4G72PZ-2G9E2TK (Micron) match this module on every key specification (32 GB, DDR4-2933, RDIMM, 2Rx4). Keep vendors consistent within a memory bank, and check your server's qualified parts list for edge cases.
What does 2Rx4 mean?
Two ranks of DRAM chips, each 4 bits wide ("×4"). Rank organization affects how many modules a memory controller can drive at full speed, so it's listed as a key spec.
