512GB DDR4 ECC kit for ThinkMate servers

This registered DDR4 kit delivers 512GB across four 128GB modules built for ThinkMate rackmount servers. ECC error correction and registered signalling protect data integrity in multi-socket workloads. The kit targets IT teams expanding memory capacity in qualified ThinkMate platforms.

DDR4 3200 registered DIMM limits

DDR4 3200 sets the peak transfer rate at PC4-25600 while the registered buffer adds one cycle of command latency. Four-rank 4Rx4 organisation increases electrical load, so maximum supported capacity depends on the server memory-controller specification. Mixed-rank populations may reduce achievable speed below 3200 MT/s.

4Rx4 rank density decides fit

Each 128GB module uses a 4Rx4 layout that demands a memory controller qualified for quad-rank registered DIMMs. Servers limited to dual-rank modules will not recognise the full capacity. Verify the ThinkMate model’s qualified-vendor list for 4Rx4 support before ordering.

Questions about this item

Should I choose the 512GB kit or buy single 128GB modules?

The kit ships as four matched 128GB RDIMMs tested together, so the 512GB kit guarantees rank and timing consistency across all slots.

What does the PC4-25600 rating deliver in a Thinkmate server?

PC4-25600 is the peak transfer rate at 3200 MT/s; the registered ECC modules sustain that bandwidth while correcting single-bit errors in real time.

Does the 288-pin DDR4 RDIMM interface limit capacity per slot?

Each 288-pin RDIMM slot accepts this 128GB 4Rx4 module, so the four-module kit reaches 512GB without exceeding the DDR4 RDIMM electrical spec.
