Memory supportUp to DDR5 4800 MT/s or up to DDR4 3200 MT/s; 2 channels, up to 192 GBThree channels of DDR3-1066 in Intel's exact-model product brief. A later Intel comparison chart incorrectly lists two channels; the original product brief is used here.
PCIePCIe 5.0 and 4.0; 20 lanes (Up to 1x16+4, 2x8+4); DMI 4.0 x8Intel's product brief describes X58 chipset PCIe 2.0 graphics connectivity, including two ×16 links. These are chipset connections, not CPU-integrated PCIe lanes. CPU-to-chipset QuickPath Interconnect runs at 4.8 GT/s for the 920.
ProcessIntel 745 nm; Nehalem architecture.
Coolermax operating temperature 100 °C; thermal specification PCG 2020CRequires an LGA1366/X58 platform; incompatible with LGA775 motherboards. Intel's retired specification page could not be read, so optional package temperature and separate maximum-power values are omitted.
