DDR5 4800 UDIMM kit for Thinkmate workstations

This 32 GB kit contains four 8 GB DDR5 4800 modules built for Thinkmate VSX-R5-340V12 workstations. The unbuffered non-ECC UDIMMs run at 1.1 V with CL40 latency. Each stick uses a 1Rx8 layout on a 288-pin PCB. The memory is validated for the listed system.

Single-rank 1Rx8 layout at CL40

The modules are single-rank 1Rx8 devices rated DDR5 4800 (PC5-38400) with a CAS latency of 40. They operate at the standard 1.10 V DDR5 voltage and carry no heat spreader. This combination of rank, speed and latency determines whether the kit matches the motherboard’s qualified-vendor list.

Suits Thinkmate VSX-R5-340V12 upgrades

Buyers upgrading that exact workstation can install the kit directly. Systems requiring ECC, registered DIMMs, a different pin count, or a higher speed grade should look elsewhere. Builders needing more than 32 GB or a lower latency bin must choose a different configuration.

Questions about this item

How does the 4800 MT/s speed behave once installed in a Thinkmate VSX-R5-340V12 workstation?

The kit runs at the JEDEC-standard DDR5 4800 MT/s rate, delivering PC5-38400 bandwidth without manual tuning.

What does the 288-pin DDR5 UDIMM interface determine for this memory?

The 288-pin DDR5 UDIMM form factor fits only DDR5 desktop or workstation boards that accept unbuffered non-ECC modules.

What physical clearance is needed for the four 8 GB modules in the Thinkmate chassis?

Each module is a standard-height 288-pin UDIMM without a heat spreader, so they occupy four adjacent DIMM slots with no extra vertical clearance.
