Designed for ASRock IMB-A1302 and IMB-A1700

This 64 GB kit contains two 32 GB DDR5 UDIMMs built for ASRock Industrial micro-ATX boards IMB-A1302 and IMB-A1700. Each module runs at 5600 MT/s with CL46 latency at 1.1 V. The non-ECC unbuffered design targets desktop and workstation workloads on these specific platforms.

Two-module kit enables dual-channel operation

The matched pair activates dual-channel mode on supported boards, doubling memory bandwidth compared with a single stick. No heat spreaders are fitted, keeping the modules low-profile for tight chassis clearance. The 2Rx8 organisation and 288-pin layout follow the DDR5 UDIMM standard.

Verify board model and slot availability

Confirm your motherboard is exactly IMB-A1302 or IMB-A1700 before ordering. Ensure two free DDR5 UDIMM slots exist and that the BIOS is current enough to initialise 5600 MT/s modules. This kit is not ECC or registered memory and will not suit server platforms requiring those features.

Questions about this item

Will the modules need active cooling or thermal pads added over time?

No heat spreader is fitted to the UDIMMs, so they rely on case airflow alone; no maintenance cooling is required.

At what point does CAS latency CL46 become the bottleneck in sustained workloads?

CL46 at 5600 MT/s sets the baseline latency; bandwidth scales with the dual-rank 2Rx8 organisation before latency limits throughput.

How much power do the two 32 GB sticks draw at 1.1 V during all-day operation?

The kit runs at 1.1 V; total draw stays within standard DDR5 UDIMM limits for continuous use.
