  • 288-pin DDR4 form factor fits standard server memory sockets

Target Server Platforms

This 256GB kit delivers 2 x 128GB DDR4 2133 registered ECC modules for enterprise servers requiring high-capacity memory. The 288-pin DIMMs operate at PC4 17000 speed and use a 4Rx4 rank organisation. It suits administrators upgrading compatible platforms that accept registered error-correcting memory.

DDR4 2133 Bandwidth Limit

The DDR4 2133 interface caps peak transfer rate at PC4 17000, so throughput cannot exceed that ceiling regardless of processor capability. Registered buffering adds one clock cycle of latency versus unbuffered DIMMs, a fixed trait of the registered standard. Systems not designed for registered ECC will not post with these modules installed.

4Rx4 Rank Density Constraint

Each 128GB module presents a 4Rx4 organisation that demands a memory controller qualified for quad-rank loads. Platforms limited to dual-rank or single-rank DIMMs will not recognise the full capacity or may fail to boot. Verify the server qualification list before purchase.

Pytania dotyczące tego produktu

Should I choose the 256GB kit or buy single 128GB modules instead?

This kit supplies 256GB as a matched pair of 128GB modules, tested together for multi-channel stability. Buying singles risks mixing ranks or production lots, which can prevent the server from posting at the rated 2133 speed.

What does the DDR4 2133 (PC4 17000) rating deliver inside a server?

It sets a peak transfer rate of 17000 MB/s per module at 2133 MT/s. Real throughput depends on the CPU memory controller, the number of populated channels, and the 4Rx4 rank layout of these 128GB sticks.

How does the 288-pin DDR4 registered ECC interface limit what I can install?

The modules fit only DDR4 RDIMM slots that accept 4Rx4 registered ECC memory. The memory controller must support 128GB per DIMM and the 2133 data rate; older platforms capped at lower densities will not recognise the full capacity.
