32GB DDR4 3200 UDIMM kit

This NEMIX RAM kit supplies 32GB of DDR4 memory as two 16GB unbuffered UDIMM modules. Rated at 3200 MT/s with CL22 latency, the modules run at 1.20V and use 2Rx8 organisation. They are built with major OEM chips and carry no heat spreader.

Suits ASRock B660M board upgrades

The kit is validated for ASRock B660M PG Riptide, B660M Phantom Gaming 4, B660M Pro RS and similar B660M motherboards. Builders needing ECC, registered modules, lower latency or higher frequencies should look elsewhere.

2Rx8 rank decides board compatibility

The 2Rx8 dual-rank layout is the specification that determines whether the memory will initialise on the target ASRock B660M platform. Verify the board's qualified vendor list for 2Rx8 support before purchasing.

Questions about this item

Does my motherboard need four DDR4 UDIMM slots to install both 16 GB modules?

The kit contains two 16 GB DDR4 UDIMM sticks, so two free 288-pin slots are sufficient.

Will the CL22 timing force the whole system to run slower if I keep my existing CL16 DDR4 memory?

The motherboard will run all installed DDR4 modules at the slowest common speed and latency, so mixing CL22 with tighter timings lowers overall memory performance.

How can I confirm the kit is running at 3200 MT/s after installation?

Open Task Manager or BIOS and verify the memory speed reads 3200 MT/s (PC4-25600) with CL22 latency reported.
