Our take on the 512GB Kit (8x64GB) 4Rx4 DDR4 2133MHz (PC4-17000) LRDIMM

This is a matched kit of eight 64GB DDR4 LRDIMMs running at 2133MHz (PC4-17000), for 512GB total. The modules are 4Rx4 load-reduced registered DIMMs, the type servers need to reach very large memory capacities without overloading the memory controller. They are listed as an upgrade for the ASRock Rack ROMED8-2T, an EPYC server board. Buyers should confirm their board and CPU support LRDIMMs at this speed before ordering, since LRDIMMs are not interchangeable with RDIMMs or unbuffered DIMMs.

Best forPopulating an ASRock Rack ROMED8-2T to its full memory capacityVirtualization and database hosts that need hundreds of gigabytes of RAMBuyers building a single large-memory server rather than many small ones
Pros
  • 512GB total in one matched eight-module kit
  • Load-reduced 4Rx4 design supports high capacity per channel
  • 2133MHz speed is broadly compatible with first- and second-generation EPYC platforms
  • Matched modules reduce the risk of mixing mismatched parts
  • 64GB per module leaves room to scale further on boards with more slots
Cons
  • LRDIMMs only work on boards and CPUs that explicitly support them
  • 2133MHz is slow by current DDR4 standards, so bandwidth is modest
  • Eight modules is a large commitment; a partial kit may suit smaller builds
  • No heatsinks or other extras; plain server DIMMs

Questions and answers

Will this kit work in my server?
Only if your motherboard and CPU support DDR4 LRDIMMs at 2133MHz. The kit is listed for the ASRock Rack ROMED8-2T; check your board's qualified memory list before buying.
What is the difference between LRDIMM and RDIMM?
LRDIMMs buffer the data lines as well as the address lines, which lets a board carry more capacity per channel. They are not interchangeable with RDIMMs, so a board that takes one type generally will not take the other.
Is 2133MHz fast enough?
It is the base DDR4 speed and fine for memory-capacity workloads like virtualization and databases. For bandwidth-heavy work, faster DDR4 kits give more throughput if the platform supports them.
Can I install only some of the eight modules?
You can, but you lose the matched-kit benefit and total capacity drops accordingly. Follow your board's population rules for balanced channel use.
What is in the box?
Eight 64GB DDR4 LRDIMMs, 4Rx4, 2133MHz (PC4-17000), for 512GB total.
Where is the 512GB Kit (8x64GB) 4Rx4 DDR4 2133MHz (PC4-17000) LRDIMM cheapest?
At A-Tech Memory, for $2,554.74, as of our latest check.
Where can I buy the 512GB Kit (8x64GB) 4Rx4 DDR4 2133MHz (PC4-17000) LRDIMM?
