Memory Pair Installation   

When installing DIMM modules, you must install the first two memory modules in 

DIMMA_DIMM1 and DIMMB_DIMM1.  

Both modules must be the same in both size and density. Modules must also use the 

same chip configuration, as in each module that is installed must physically have the 

same number of memory chips on them.  

All memory sockets must be populated by the same memory type, either x4 modules or 

x8 you cannot mix and match x4 and x8 modules together.

Points to remember: 

At least two Registered ECC DDR SDRAM modules must be installed for the 

system to turn on and POST (Power On Self Test). Single Channel memory 

support is not currently available. Please check Tyan's website for updates on 

this topic. 

When installing modules, install them in this order: DIMMA_DIMM1, 

DIMMB_DIMM1, DIMMA_DIMM2, DIMMB_DIMM2, etc. 

128MB, 256MB, 512MB, 1GB, and 2GB Registered ECC PC2100/PC1600 

DDR SDRAM memory modules are supported in x4 or x8 configuration. 

The Tiger i7501R S2735 supports up to 12GB of memory with 2GB (X4) 

registered DDR modules. 

Use ONLY x8 OR x4 type memory modules. Mixing memory types may affect 

stability.
