NEMIX RAM 64GB DDR4 3200 Kit

This NEMIX RAM kit provides 64GB of DDR4 memory across two 32GB UDIMM modules. It is built for desktop PCs using ASRock B450M motherboards that support DDR4 3200 speeds. The modules run at 1.20V with CL22 latency.

288-pin unbuffered non-ECC upgrade

Each module uses a standard 288-pin DDR4 UDIMM form factor with 2Rx8 organisation. The kit is unbuffered and non-ECC, so it fits directly into consumer desktop DIMM slots without requiring registered or error-correcting memory support. No heat spreaders are included.

Suits ASRock B450M capacity upgrades

This kit suits builders maximising memory on a compatible ASRock B450M board with four slots or populating two slots fully. It is not for systems limited to 32GB total capacity or boards that only accept single-rank modules. Buyers needing ECC or registered memory should look elsewhere.

Questions about this item

Will the CL22 latency throttle performance during long rendering sessions?

The kit runs at CL22 timing as specified; sustained workloads will operate at that latency without additional throttling from the modules themselves.

How much heat do the modules produce when running continuously at 3200 MHz?

These UDIMMs operate at 1.2 V with no heat spreader, so they generate only modest heat typical of standard DDR4 at stock voltage.

Does my ASRock B450M board need a BIOS update before installing this 64 GB kit?

The kit is validated for ASRock B450M motherboards; most current BIOS revisions will recognise the 2Rx8 modules at 3200 MHz automatically.
