256GB DDR4 2933 kit for Supermicro workstations

This eight-module kit delivers 256GB of DDR4 2933 memory in matched 32GB UDIMMs. It is built for Supermicro C9X299-PGF motherboards used in desktop workstations and gaming systems. The non-ECC unbuffered design suits platforms that do not require registered or error-correcting modules.

Eight matched sticks simplify full population

Supplying eight identical 2Rx8 modules removes the guesswork of mixing capacities or ranks when filling all slots. The kit arrives pre-tested as a set so the memory controller sees consistent timing across every channel. No extra software or heat spreaders are included in the package.

Verify board slot count and maximum capacity

Confirm the motherboard has eight 288-pin DDR4 slots and supports 256GB total with 32GB UDIMMs at 2933 MT/s. Check that the BIOS recognises non-ECC unbuffered 2Rx8 modules at 1.20V. Systems limited to fewer slots or lower per-slot limits will not accept the full kit.

Questions about this item

Will the 2Rx8 DDR4 modules require any firmware updates or component replacements over time?

The kit uses standard JEDEC DDR4 2933MHz CL21 1.2V unbuffered DIMMs with no heat spreaders; no firmware or scheduled part replacements are needed.

What limit appears first when all eight 32GB sticks run continuously at 2933MHz?

The motherboard's maximum supported memory capacity and available 288-pin slots set the hard ceiling for this 256GB configuration.

How much heat and power should I expect from the 1.2V DDR4 kit during all-day workloads?

Each module draws 1.20V at stock speed with no heat spreader, so thermal output stays within standard DDR4 limits for unbuffered UDIMMs.
