The code computes eff_model but does not take the extended model number into account for model 0x06 CPUs (for example, eff_model is computed as 0xa on my SandyBridge system, when it should be 0x2a). Other family 0x6 models I know of so far are: 0x1 Pentium Pro 0x3 Pentium Pro 0x5 Pentium II, Xeon 0x6 Celeron 0x7 Pentium III, Xeon 0x8 Pentium III, Xeon 0x16 Celeron (65 nm) 0x17 Core 2, Xeon (45nm) 0x1A Core i7 LGA1366 (45nm) 0x1C Atom (45nm) 0x1D Xeon MP (45 nm) 0x1E Core i5, i7 LGA1366 (45nm) 0x1F Core i5, i7 0x25 Core i3, i5, i7 LGA1156 (32nm) 0x2A Core i5, i7 2xxx LGA1155 (32nm) 0x2C Core i7 LGA1366 (32nm) 6 Core 0x2D SandyBridge Xeon 0x2E Xeon 7500 (45 nm) 0x2F Xeon 7500 (32 nm) Presumably we would want to know the VRM version for those to be able to support them correctly. I hoped there was an easier version to find the VRM version than by searching through the various datasheets.
