System-Specific DDR5 ECC RDIMM Kit

This 32 GB kit contains two 16 GB DDR5 4800 registered DIMMs built for THINKMATE SuperServer 511E-WR and 521E-WR platforms. ECC and registered buffering protect data integrity in continuous server workloads. The modules run at 1.1 V with CL40 latency and use a 288-pin RDIMM form factor. No heat spreaders are fitted, matching the original server specification.

Suited For And Not Suited For

Ideal for administrators upgrading or repairing the listed Thinkmate Supermicro servers where validated ECC registered memory is required. Not suitable for desktop motherboards that accept only unbuffered non-ECC DIMMs. Buyers needing higher capacities per module or faster JEDEC speeds should look at other qualified kits. Systems requiring registered LRDIMM or 3DS modules cannot use this kit.

Deciding Specification

The registered ECC RDIMM design with 1Rx8 organisation at DDR5 4800 CL40 is the single specification that determines compatibility. Only platforms qualified for this exact module type will post and run stably. Verify the server memory QVL before purchase.

Questions about this item

How do I install these 288-pin DDR5 RDIMMs in a Thinkmate 511E-WR, and which step is commonly missed?

Power down, open the chassis, align the notch on each 288-pin module with the slot key, press firmly until both side clips click, then verify in BIOS that both 16 GB sticks register at 4800 MT/s; the step often missed is fully seating both clips so the registered buffer initialises correctly.

What maintenance or replacement will this 32 GB ECC RDIMM kit need over its service life?

No scheduled maintenance is required; ECC corrects single-bit errors on the fly, and if a module ever fails the lifetime replacement warranty covers a direct swap of the defective 16 GB stick.

What limit appears first when this CL40 1.1 V kit runs sustained workloads on a Thinkmate 521E-WR?

The CAS latency of CL40 at 4800 MT/s sets the timing ceiling; under continuous load the memory controller will hit that latency boundary before voltage or thermal limits become a factor.
