3.4 – Installing the Memory
Before attempting to install any memory, make sure that the memory you have is compatible with
the motherboard as well as the processor. For this information, please check TYAN’s web site at:
www.tyan.com
The following diagram shows the types of RAM modules you may encounter depending on your
board:
DDR Unbuffered ECC
DDR Unbuffered
Here are a few key points to note before installing memory into your Tiger i7525 (S2672):
128MB, 256MB, 512MB and 1GB Registered ECC DDR2-400
•
All installed memory will be automatically detected - no need to set any jumpers
•
The Tiger i7525 (S2672) supports up to 4GB of memory
•
Unbuffered Memory is NOT supported
.
You can install memory in either a Single Channel or Dual Channel
configuration. Please note that the same type and density memory modules are
necessary while using dual-channel DDR, otherwise it may cause system instability.
Please refer to the chart below for the proper way to install the modules.

Supported System Bus Frequency and Memory Speed Combinations
To use this type of DIMM… The processor’s system bus frequency must be…
DDR2-400 800MHz
NOTE:
While using ECC type memory, it will take longer time to post. Due to the manner in which it
counts the memory and has to write zero’s to every bit of the stick before progressing through the
POST.
