Server-grade DDR4 3200 kit

This 512GB kit consists of four 128GB registered DIMMs built for THINKMATE rackmount servers. ECC and registered operation protect data integrity in mission-critical workloads. The modules run at 1.20V with CL22 latency and a 4Rx4 organisation. They target administrators who need maximum capacity per slot in qualified platforms.

DDR4 3200 registered interface

The PC4-25600 standard caps transfer rate at 3200 MT/s and requires a registered buffer on each module. CL22 timing sets the minimum access delay at this speed. ECC adds single-bit correction and multi-bit detection but consumes one extra bit per byte. The 288-pin RDIMM form factor only fits DDR4 RDIMM slots; it will not work in UDIMM or LRDIMM sockets.

512GB total across four slots

Four 128GB ranks deliver the full 512GB when all slots are populated. This density suits large in-memory databases and virtualisation hosts that benefit from local capacity. Systems limited to fewer than four RDIMM slots or lower per-slot limits cannot use the full kit. Buyers needing more than 512GB per server must look beyond this configuration.

Questions about this item

Should I choose the 4x128GB kit or a different capacity for my Thinkmate server?

This kit provides 512GB total across four 128GB modules, matching the Thinkmate RAX-XS4-21S1-10G, RAX-XS4-11S1-10G and RAX-XH2-11S3 validated configurations.

What does DDR4-3200 CL22 mean for actual throughput in a registered ECC server?

The modules run at 3200 MT/s with 22-cycle CAS latency; the registered buffer adds one cycle but allows the memory controller to drive all four ranks per DIMM without signal degradation.

How does the 288-pin RDIMM interface limit speed and capacity on my Thinkmate platform?

The 288-pin DDR4 RDIMM slot caps at the JEDEC DDR4-3200 rate; each 4Rx4 module presents four logical ranks so the four-DIMM kit delivers 512GB within the server's supported rank count.
