This 32GB memory is 100% compatible with Fujitsu Primergy TX300 S8. Our memory team will be happy to help you choose the right memory and configure your server.TechnologyRAM per CPURam per CPU (12 memory slots, 3x memory slot à 4 memory channels)UDIMM ECC64GB RAM (8 x 8GB ECC UDIMM)RDIMM 2Rank192GB RAM (12 x 16GB RDIMM)RDIMM 4Rank256GB RAM (8 x 32GB RDIMM)LRDIMM768GB RAM (12 x 64GB LRDIMM)ECC DIMM, Registered DIMM and Load Reduced LRDIMM memory modules must not be mixed. When upgrading, you should therefore know which memory is already present or upgrade completely to RDIMM memory.Principles of memory configurationThere are 4 memory channels per CPU, each with 3 memory slotsECC DIMM, Registered DIMM and Load Reduced LRDIMM memory modules must not be mixedWhen using ECC UDIMM or 4Rank (4Rx..) RDIMM memories, only 2 of 3 memory slots per memory channel can be occupiedMemory slots for which no processor is available must not be fittedMemory configuration for good system performancer a good system performanceDistribute the memories evenly across the memory slots and evenly across the CPUsIf more than one CPU is available, the memories per CPU should be populated identically (mirrored to the other CPU).
