For ThinkStation P500: Your computer has eight slots for installing or replacing DDR4 DIMMs that provide up to a maximum of 256 GB system memory. When installing or replacing a memory module, use the following guidelines: • Use DDR4 ECC UDIMMs, DDR4 ECC RDIMMs, or DDR4 ECC LRDIMMs for your computer. Do not install any combination of UDIMMs, RDIMMs, and LRDIMMs into the same computer. • Use 4 GB DDR4 ECC UDIMMs in any combination up to a maximum of 32 GB. • Use 4 GB, 8 GB, or 16 GB DDR4 ECC RDIMMs in any combination up to a maximum of 128 GB. • Use 32 GB DDR4 ECC LRDIMMs in any combination up to a maximum of 256 GB. • Always install DIMMs in the following order as illustrated: Figure 84. Memory module installation order for ThinkStation P500 For ThinkStation P700: Your computer has 12 slots for installing or replacing DDR4 DIMMs that provide up to a maximum of 384 GB system memory. When installing or replacing a memory module, use the following guidelines: • Use DDR4 ECC UDIMMs, DDR4 ECC RDIMMs, or DDR4 ECC LRDIMMs for your computer. Do not install any combination of UDIMMs, RDIMMs, and LRDIMMs into the same computer. • Use 4 GB DDR4 ECC UDIMMs in any combination up to a maximum of 48GB. • Use 4 GB, 8 GB, or 16 GB DDR4 ECC RDIMMs in any combination up to a maximum of 192 GB. • Use 32 GB DDR4 ECC LRDIMMs in any combination up to a maximum of 384 GB. • If your computer has only one microprocessor installed, install memory modules only in the memory slots adjacent to that microprocessor. Note: Ensure that the microprocessor is installed into the microprocessor socket on the right side. • If your computer has two microprocessors installed, install equal numbers of memory modules in both sets of microprocessor DIMM slots for maximum performance. 124 ThinkStation P500 and P700 User Guide
