Samsung 32GB DDR4-2666 ECC RDIMM M393A4K40CB2-CTD PC4-21300 2Rx4 Server RAM
Price: US $119.99

You are purchasing a genuine Samsung 32GB DDR4-2666 ECC Registered DIMM (M393A4K40CB2-CTD), pulled from production servers during a planned hardware refresh. Samsung is a Tier-1 DRAM manufacturer — the same OEM-grade silicon specified and certified by Dell, HPE, Lenovo, and Supermicro for their Gen10 server platforms. This is not a compatible or aftermarket module. It's the real thing.

DDR4-2666 is the native operating speed for Intel Xeon Scalable Gen1 and Gen2 platforms, making this module a direct, no-compromise drop-in for the largest installed base of current-generation enterprise servers in the field. If you're running a Dell PowerEdge R640, R740, R750, an HPE DL360/DL380 Gen10, or a Supermicro X11 platform — this is exactly what your system expects.
