[kenny chia]

Hi all
besides the number of expansion slots for PCI, memory and disks, are there any differences between these 2? is the rx5670 more reliable?

Both are 4 processor systems.
Here are the major differences:
4640 5670
Max memory 64GB 96GB
Disks 2 4
PCI Slots 6 10

The 4640 can have a low profile DVD drive. No internal tape options.
The 5670 has a DVD DAT Tape option.

Also, the 4640 has a Dual Core mx2 1.1 GHz processor option. This gives you 8 processors.
