Server memory kit 256GB

This 256GB kit contains eight 32GB DDR5 RDIMM modules rated at 6400MHz with CL52 latency and 1.1V operation. Registered ECC design with 1Rx4 organisation suits server platforms that require buffered memory. Modules use 288-pin form factor and PC5-51200 specification for enterprise workloads.

Suits ASRock Rack TURIN2D16-2T/ROT

Verified compatibility with the ASRock Rack TURIN2D16-2T/ROT motherboard ensures correct population rules and full-speed recognition. Not for systems needing UDIMM or SODIMM form factors. Builders requiring non-ECC unbuffered memory should choose a different product type.

Registered ECC DDR5 6400MHz

Registered buffering offloads the memory controller so all eight slots run fully populated at rated speed. ECC corrects single-bit errors on the fly to prevent silent data corruption. This specification determines whether the kit matches your server's qualified vendor list.

Questions about this item

What does DDR5-6400 CL52 actually deliver once installed in a server?

The kit runs at 6400 MT/s with CAS latency 52, giving 51200 MB/s peak bandwidth per module while the registered buffer keeps all eight slots stable at full 256 GB capacity.

How does the 288-pin RDIMM interface and PC5-51200 rating limit real-world speed?

The 288-pin RDIMM form factor and PC5-51200 spec lock the modules to 6400 MT/s at 1.1 V; the memory controller cannot exceed this data rate without overclocking, which the registered design discourages.

What physical clearance and slot layout does the 8×32 GB kit require?

Eight 288-pin RDIMM slots are needed; each module is a standard-height registered DIMM with no heat spreader, so they fit the ASRock Rack TURIN2D16-2T/ROT population order without extra vertical clearance.
