SuperMicro Compatible DDR4 UDIMM

This 8 GB DDR4 module is built for SuperMicro desktops, gaming rigs and SuperWorkstation systems. It targets administrators and builders who need a single, validated stick to expand memory in qualified platforms.

8 GB capacity and 2933 MT/s headroom

The stick delivers 8 GB of non-ECC unbuffered memory at DDR4 2933 (PC4-23400) with CL21 latency and 1.20 V operation. It handles typical workstation workloads and mainstream gaming; larger datasets or multi-channel bandwidth demands will exceed the single-module limit.

DDR4 UDIMM interface constraints

The 288-pin UDIMM form factor fits standard DDR4 slots but cannot be used in DDR5, registered or ECC-only motherboards. Systems requiring registered DIMMs, higher densities per slot or error-correcting memory need a different module type.

Questions about this item

Will this DDR4 2933 CL21 stick run stably alongside slower DDR4 modules I already have in my SuperMicro workstation?

Yes — the module is JEDEC-standard DDR4-2933 at 1.20 V with CL21 timing, so the system will automatically down-clock all sticks to the slowest installed speed and tightest common timings.

How can I confirm the module is recognised at 2933 MT/s and CL21 after I install it?

Check the BIOS memory information screen or run CPU-Z / dmidecode; both will show the configured speed as 2933 MT/s and the active CAS latency as 21.

Does the single 8 GB UDIMM ship alone or with any extra brackets, cables or tools?

Only the 288-pin DDR4 UDIMM itself is included; no heat spreader, brackets, cables or installation tools are supplied.
