Dram Installation - TYAN TITAN TURBO AT User Manual

3.10 DRAM Installation

The S1570 uses a 64-bit data path from memory to CPU and can
accommodate up to 256MB of RAM. The mainboard supports Fast Page
Mode, and EDO (Extended Data Out) 72 pin SIMMs.
SDRAM(Synchronous) are also supported in the DIMM slots. DIMM's
must be of the unbuffered variety. All installed memory will be automati-
cally detected so there is no need to set jumpers. The TX chipset can
cache up to 64MB of RAM.
w SIMM modules must be installed in pairs.
w Each pair of SIMMs must be of the same size and type.
w The mainboard supports 1, 2, 4, 8 and 16MBx32 SIMMs.
w SIMM bank 0, 1 and 2 can use either double or single sided SIMMs.
w Two SIMMs or One unbuffered DIMM must be installed for the system
to POST.
w SDRAM DIMMs can be installed one at a time.
w The mainboard supports 1, 2 and 4Mx 64 DIMM modules.
w SIMM bank 0 and DIMM bank 0 cannot be used at the same time.
SIMM bank 1 and DIMM bank 1 cannot be used at the same time.
You can use SIMM bank 0 with DIMM bank 1.
You can use SIMM bank 1 with DIMM bank 0.
w If you use 4Mx64 DIMMs you cannot use DRAM bank 2.
w We do not recommend using DRAM bank 2 along with DIMMs.
w The following table shows some of the available memory configurations.
