64GB DDR4 3200 ECC RDIMM kit

This 64GB kit contains four 16GB DDR4 3200 registered DIMMs with ECC and CL22 latency. It is built for THINKMATE HDX-QT24 and HDX-QN24 high-density servers that require registered memory. The modules operate at 1.2V and use 2Rx8 organisation.

DDR4 3200 registered interface limits

The DDR4 3200 standard caps transfer rate at 25600 MT/s and the registered buffer adds one cycle of command latency. CL22 timing is the rated figure; tighter latencies are not guaranteed at this speed. ECC function requires a motherboard that supports registered ECC DIMMs.

Four-slot capacity and headroom

The 64GB total fills four DIMM slots with 16GB each, matching the validated population for the listed THINKMATE platforms. Systems needing more than 64GB or a different rank configuration would require a different module density or rank arrangement.

Questions about this item

Should I pick the 4 x 16 GB kit or a different capacity for my THINKMATE server?

This kit provides 64 GB total across four 16 GB modules, matching the 2Rx8 rank structure validated for the listed HDX-QT24 and HDX-QN24 models.

What does the 3200 MT/s rating deliver in a registered ECC environment?

The DDR4 3200 (PC4-25600) modules run at 1.20 V with CL22 latency, giving the maximum JEDEC-standard throughput the platform’s memory controller supports.

How does the 288-pin RDIMM interface affect usable speed and capacity?

The registered 288-pin DDR4 RDIMM format enables ECC error correction and signal buffering, allowing all four modules to operate at the rated 3200 MT/s without exceeding the platform’s electrical load limits.
