Fujitsu PRIMERGY Server Memory: RX, TX, CX & GX Servers

Memory upgrades matched to your Fujitsu PRIMERGY server. Each listing covers one PRIMERGY model and one memory type, with the speed, module sizes and kit sizes that model supports. To find yours, type the model into the search bar at the top of the page, for example RX2540 M8, RX2530 M7, RX2450 M2, RX2540 M5, TX2550 M5 or TX300 S7. You can also search by Fujitsu part number, such as PY-ME64SP or S26361-F4083-E332. The model name is on the front panel and the system ID card. For help identifying your server, see the Fujitsu PRIMERGY memory guide.

RDIMM, LRDIMM or ECC UDIMM?

DDR5 PRIMERGY servers take registered memory (RDIMM). On DDR4 and DDR3 servers, Fujitsu does not allow registered (RDIMM) and load-reduced (LRDIMM) modules in the same server: match what is already installed, or replace all modules at once. LRDIMMs reach the highest DDR4 and DDR3 capacities. The single-socket Intel models (RX1330, TX1330, TX1320 and TX1310) take ECC unbuffered memory (ECC UDIMM) only.
