Hardware

Hi all,

I want upgrade RAM memory in our server, now we have 16x2GB RAM in use.

At the service manual for T5140 server are some constraints for memory upgrading:

■ Use only 1.5-volt FB-DIMMs in SPARC Enterprise T5140 and T5240 servers.
■ All FB-DIMMs within a single CMP branch must have the same capacity.
■ If the System Firmware is at least version 7.1.7.f, the FB-DIMM capacities on
different CPUs can be different.

I would like to purchase two 8GB RAM module and I would like to use following module layout at motherboard:
2|2|2|2 - 2|2|2|2 -- 2|2|2|2 - 8|0|0|8
where 2 is 2GB module, 0 is empty slot and 8 is 8GB module. But if I checked service manual it seems that it isn't allowed combination. I am right?


Also I would like to know if is possible to run memory modules with 1.8V, for example: http://www.crucial.com/store/mpartspecs.aspx?mtbpoid=D4E89A25A5CA7304 ... they write that it is memory for T5140 but in specification below is following: DDR2 PC2-5300 • CL=5 • Fully Buffered • ECC • DDR2-667 • *1.8V* • 1024Meg x 72. I found many memory with this "problem" and I am not sure if I can use this memory. Sure, I found also these memories http://www.memoryxsun.com/t5140.html but I would like to know if the first mentioned memory is right for our server.

Many thanks for some advice
