This 32GB memory is 100% compatible with Gigabyte H261-PC0. The following technical specifications should be considered in advance: RDIMM and RDIMM 3DS (Registered DIMM) or LRDIMM and LRDIMM 3DS (Load Reduced DIMM) RAM memory can be installed in the unit. LRDIMM memories are recommended when large memory capacities are to be achieved. RDIMM and RDIMM 3DS memory modules cannot be operated mixed together with LRDIMM and LRDIMM 3DS RAMs. If a memory expansion is to be made with the RAMs already present, it must be checked which basic memory technology (RDIMM / LRDIMM) is available. When using a multiprocessor system, the memory slots should always be populated identically for each CPU. Memory slots for which no processor is present must not be populated. If memory modules are offered with higher clock rates than specified by the system, the memory clock automatically adjusts to the system specifications. Maximum memory speed of the possible CPUs: Xeon CPUs of the 2nd generation are offered as Bronze, Silver, Gold, or Platinum. The different processor series each support different maximum clock frequencies: Xeon CPU series, max speed MHz, max memory capacity per CPU: Bronze 3200, 1331 TB; Silver 4200, 2400 TB; Gold 5200, 2661 TB, 2 TB, 4.5 TB; Gold 6200, 2661 TB, 2 TB, 4.5 TB; Platinum 8200, 2933 TB, 1 TB, 2 TB, 4.5 TB; Platinum 9200, 2933 1.5 TB.
