AS1020S-8 User's Manual

Optimizing memory performance

If two processors are installed, it is better to stagger pairs of DIMMs across both sets of CPU DIMM slots, e.g. fi rst populate CPU1 slots 1A and 1B, then CPU2 slots 1A, and 1B, then the next two CPU1 slots, etc. This balances the load over both CPUs to optimize performance.

Maximum memory (two CPUs): 32 GB for DDR333/266 and 16 GB for DDR400. If only one CPU is installed, maximum supported memory is halved (16 GB for DDR333/266 and 8 GB for DDR400).

To Install:

Insert module vertically and press down until it snaps into place. The release tabs should close - if they do not you should close them yourself.

To Remove:

Use your thumbs to gently push each re- lease tab outward to release the DIMM from the slot.

Note the notch in the slot and on the bottom of the DIMM. These prevent the DIMM from being installed incorrectly.
