128GB DDR5 OC R-DIMM Kit

V-color OC R-DIMM DDR5 provides 128GB across four 32GB registered modules. Each stick runs at 6200MHz with CL32 timings and on-die ECC for data integrity. The kit uses SK Hynix ICs on a 10-layer PCB with an on-board PMIC. It is built for AMD TRX50 workstation platforms.

For ECC Workstation Builds

This memory suits professionals who need registered ECC DDR5 on Threadripper PRO 7000 series systems. The EXPO profile simplifies overclocking setup on TRX50 motherboards. Buyers who need unbuffered UDIMMs or non-ECC modules for consumer platforms should look at something else.

6200MHz EXPO Registered Speed

The decisive specification is the 6200MHz AMD EXPO profile on registered DDR5. Your TRX50 motherboard must support this EXPO frequency for the kit to run at rated speed. Verify the qualified vendor list before purchase.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules on a TRX50 motherboard, and what step is often missed?

Align the notch on each 288-pin module with the slot key, press firmly until both retention clips click, then enable the AMD EXPO profile in BIOS to activate the 6200 MT/s speed; skipping the EXPO step leaves the kit at JEDEC defaults.

What maintenance or replacement will the 128 GB kit need over its service life?

The modules use SK Hynix ICs on a 10-layer PCB with on-board PMIC and on-die ECC; no user-serviceable parts exist, so replacement is only required if a module fails validation or a capacity upgrade is desired.

What limit appears first when the 4 x 32 GB kit runs sustained workloads at 6200 MT/s CL32 1.40 V?

The on-die ECC and PMIC manage signal integrity and voltage regulation, so the practical ceiling is thermal — prolonged heavy traffic can raise module temperature until the PMIC throttles or the system firmware reduces frequency to protect the 2Rx8 ranks.
