1.4.2 DIMM
DRAM Access Time: 2.5V Unbuffered DDR SDRAM PC 200/266 Type
required.
DRAM Type: 128MB/ 256MB/ 512MB DIMM Module (184 pin)
Due to the limitation of chipset, this board only can support up to 2 banks of DDR
memory.
However, in the market, there are so many single-sided modules occuping half bank.
BIOSTAR would like to utilize the modules as many as possible. So we divide each
bank into 2 sockets. That means any bank just can support one double-sided or two
single-sided modules only. Please refer to the following table for appropriate usage.
DDR1 & 2 => Bank 0, DDR3 & 4 => Bank 1.
Each Bank 0 and 1, contain 2 DDR sockets, one white & one black.
DDR1
Bank 0
DDR2
DDR3
Bank 1
DDR4
※ If you have one DDR module and you are not sure if it is a single or
double- sided DDR module, please insert in DDR1 (black color) socket
first.
※ If you have two DDR modules and you are not sure if they are single or
double-sided DDR modules, please insert in DDR1 and 3 (black color)
Sockets.
※ DDR 2 and 4, white color sockets, only support single-sided DDR
module.
For better compatibility, before insert DDR modules into the sockets, we
strongly suggest to use the same type of modules including the model, speed
and size of memory.
