ThinkMate 256GB DDR4 Kit

This NEMIX RAM kit delivers 256GB across eight 32GB UDIMM modules. It is built for ThinkMate VSX-R5-540X1 workstations that accept unbuffered DDR4 memory. The non-ECC design targets desktop and workstation platforms without registered memory support. Each module runs at 3200MHz with CL22 latency.

Eight-slot population at 1.2V

The kit fills all eight DIMM slots with 2Rx8 organisation, drawing 1.20V per module. No heat spreaders are fitted, so clearance depends only on the bare PCB height. Builders must verify that the motherboard supports eight unbuffered modules at this density and that the CPU memory controller can address the full 256GB capacity.

Suited for ThinkMate workstation upgrades

Ideal for IT teams expanding memory in validated ThinkMate VSX-R5-540X1 systems. Not suited for servers requiring registered or ECC modules, nor for platforms limited to four DIMM slots or lower maximum capacity per slot. Buyers needing error correction or registered signalling should select a different kit.

Questions about this item

Will the 3200 MT/s speed hold under sustained heavy workloads on the ThinkMate VSX-R5-540X1?

The modules run at DDR4 3200 (PC4-25600) with CL22 latency at 1.2 V, so the rated frequency is maintained as long as the workstation's memory controller and cooling keep the DIMMs within JEDEC thermal limits.

How much heat and power do the eight 32 GB sticks generate when the system runs all day?

Each 2Rx8 UDIMM operates at 1.20 V without a heat spreader; total kit power draw scales with the eight modules, and the workstation's stock airflow is designed to dissipate the resulting heat under continuous load.

What must the ThinkMate VSX-R5-540X1 already have for this 256 GB kit to work?

The workstation needs eight free 288-pin DDR4 UDIMM slots, a CPU and chipset that support 2Rx8 non-ECC unbuffered modules at 3200 MT/s, and a BIOS version that recognises the full 256 GB capacity.
