Chapter 2:Hardware Installation 2.2.4 Installing System Memory DIMM 1 DIMM 2 BANK 0 BANK 1 Single-Sided Symmetric: 1Mx64, 4Mx64, 16Mx64 Asymmetric: 1Mx64, 2Mx64, 4Mx64, 8Mx64 Double-Sided Symmetric: 2Mx64, 8Mx64 Asymmetric: 1Mx64, 2Mx64, 4Mx64, 8Mx64, 16Mx64 Requirements DRAM Speed: 60ns or faster RAS Access Time: 60ns or faster CAS Access Time: 20ns or faster FDD Module Size EDO (Extended Data Output) 1 DRAM TYPE IDE2 IDE1 The P6F94 Mainboard has two DIMM Sockets. Memory can be installed by using 168pin SDRAM DIMM or EDO DIMM memory modules. There are no jumper settings required for the memory size or type, which is automatically detected by the BIOS. Due to the P6F94 Mainboard high speed design, the memory modules for the P6F94 must meet all of the following requirement: 1 1 The maximum system memory supported by the P6F94 is 256MB. If more than 256MB memory are populated on the P6F94 mainboard, the portion of the memory which exceed the 256MB boundary will be invalidated. SDRAM (Synchronous DRAM) Single-sided Asymmetric: 1Mx64, 2Mx64, 4Mx64, 8Mx64, 16Mx64, Double-Sided Asymmetric: 2Mx64, 4Mx64, 8Mx64, 16Mx64 3.3V unbuffered DIMM module Speed grade: 66.6 MHz or faster CAS latency: 3 or faster When P6F94 equipped with Intel 82440LX chipset, it supports 64-bit or 72-bit (64-bit memory data plus 8-bit ECC) DRAM array. When P6F94 equipped with Intel 82440EX chipset, it only supports 64-bit DRAM array. The ECC function is not supported by Intel 82440EX chipset. 30 P6F94 User’s Manual
