Memory in a rx7640

[Carme Torca]

Hi,

I have this memory configuration in one rx7640.
Two cells and in one cell I have:
[MP_rx7640-12] MP:CM> CP

--------+--+
Cabinet |0 |
--------+--+
Slot |01|
--------+--+
Part 0 |.*| -> partition 0 -> celda 1
Part 1 |*.|

And I have two qüestions:

1) Why there are 8192Mg and 7680Mg in the servers? Where are the other 0,5Gb?

2) Is possible to put more Mb in this cell?. How much could I put?

Thanks a lot of,
Carmen.

Aach the MP output (unreadable here) and run cstm on both cells.

>> 1) Why there are 8192Mg and 7680Mg in the servers? Where are the other 0,5Gb?

You are running vPars, so some memory is reserved for the vPars monitor... see Appendix D (p288) of this doc:

Yes, the rx7640 has 16 DIMM slots on each cell board - you appear to have 8 DIMM slots occupied on this cell board with 2GB DIMMs. You could add another 8 DIMMs (4 memory modules as they are sold in pairs) to this system. The rx7640 supports 2GB, 4GB, and 8GB DIMMs, so you could add:

4 x AB454A (4GB memory modules/2GB DIMMs) for an extra 16GB of memory
-or-
4 x AB455A (8GB memory modules/4GB DIMMs) for an extra 32GB of memory
-or-
4 x AB456A (16GB memory modules/8GB DIMMs) for an extra 64GB of memory
