64GB DDR5 Kit for SuperMicro Workstations

This 64GB kit contains two 32GB DDR5 4800 UDIMM modules built for SuperMicro desktop and SuperWorkstation systems including the SYS-531AD-I and C9Z790-CG. It targets IT professionals and enthusiasts who need validated, non-ECC memory for compatible platforms.

Non-ECC Unbuffered Design for Direct Compatibility

The modules are non-ECC and unbuffered, matching the electrical requirements of the specified SuperMicro motherboards without registered or error-correcting overhead. Major OEM chips from Samsung, Micron or Hynix are used and each kit is stress tested under load before shipping.

Low-Profile 288-Pin UDIMM Build

A 1.10V operating voltage and CL40 latency define the electrical profile, while the 2Rx8 organisation fits the 288-pin DDR5 slot standard. No heat spreader is fitted, so clearance is minimal and installation follows the motherboard manual in minutes.

Questions sur cet article

Will the 2Rx8 DDR5 modules need any firmware updates or re-seating after the first year of continuous operation?

No firmware updates are required for these UDIMMs; they are validated at 4800 MT/s and 1.10 V and retain their JEDEC profile for the life of the module.

Does the CL40 latency at 4800 MT/s become the bottleneck before the 64 GB capacity is fully utilised in sustained workloads?

At 4800 MT/s the CL40 timing sets the access latency floor; once the working set exceeds cache, that latency is the first limit reached under sustained load.

With no heat spreader on the 288-pin sticks, how hot do they run and how much power do they draw during all-day operation?

Operating at 1.10 V, each 32 GB module draws minimal power and runs within JEDEC thermal limits without a spreader, so temperatures stay low even under continuous use.
