Capacity and form factor

This kit provides 64GB of DDR5 memory across two 32GB SODIMM modules. It is built for the ASRock Industrial IMB-X1240-WV Mini-ITX motherboard using the 262-pin DDR5 SODIMM interface.

Build integration

The modules are non-ECC and unbuffered, matching the motherboard's slot requirements. They operate at the standard 1.10V DDR5 voltage and need no additional cooling or configuration beyond a compatible BIOS.

Speed and limits

Rated at 4800 MT/s with CL40 latency, the kit delivers the baseline DDR5 data rate for this platform. The 2Rx8 organisation fills both ranks per module, so no further capacity can be added without replacing the kit.

Questions about this item

How does the 1.1V operating voltage affect heat output during continuous workloads on the IMB-X1240-WV?

The 1.1V DDR5 design reduces power draw compared to earlier generations, limiting heat buildup during all-day operation on the ASRock board.

Does the CL40 latency create a bottleneck when the 64GB kit runs at 4800MT/s for extended periods?

CL40 is the standard timing for JEDEC DDR5-4800; the 2Rx8 organisation keeps throughput steady under sustained loads.

What motherboard slot layout does the 262-pin SODIMM kit require on the IMB-X1240-WV?

The kit installs in two 262-pin DDR5 SODIMM slots on the ASRock IMB-X1240-WV Mini-ITX motherboard.
