Performance Tips (six slot Genesis MP):
The six PCI slots are grouped into two groups of three each. Because the circuitry
linking the top three PCI slots is also used for other motherboard I/O, most expansion
cards perform slightly faster when installed in one of the bottom three PCI slots.
If you are installing a SCSI array with two PCI cards, you can typically increase
performance by installing one card in one of the top three PCI slots and the second
card in one of the bottom three PCI slots.

Upgrading the nPOWER Processor Card
Genesis MP’s processors are found on an exchangeable daughtercard. They are
designed this way so that you are able to easily increase the performance of your
machine as faster processors become available.
To upgrade your processor daughtercard:
1. Open Genesis MP (loosen the side door panel) by following the easy instructions
listed previously in this chapter. Remember to turn everything off.
2. Put on your anti-static wrist strap.
3. Disconnect the power connector from the nPOWER card. Be sure to disengage the
connector lock as you pull the plug.
