L2 Cache
The TransPort NX supports a 512KB L2 write back cache with synchronous
pipeline burst mode, 128 KB or 256KB of full bus speed on-die L2 write back
cache with synchronous pipeline burst mode.
Upgradeable System Memory
The TransPort NX has a 64-bit memory bus. Memory can be upgraded to 384MB
by the following options:
•
One, two or three 32, 64, or 128MB 144-pin, 3.3V, SDRAM SO-DIMM
modules.
When you want to upgrade memory: Turn off the computer, open the palmrest,
and lift the keyboard carefully without scratching the very fragile LCD. Follow
either procedure below to add or remove memory.
You will now see three memory slots as follows:
Figure 10. Memory Slots
To Remove Memory
1. Press both metal tabs on either side of the memory module away from the
module until the module pops free.
2. Remove the module carefully at a 45 degree angle. Avoid touching the
SDRAM module on any of its static-sensitive circuitry.
3. Store the module in a static free bag.
To Install Memory
1. Ensure the key on the memory slot is lined up with the key on the module
(there will be two slots on the module; it will only fit into the slot one way).
2. Insert at a 45 degree angle.
3. Once it is in the slot, press down the module. You will hear a small clickwhen
the memory module is firmly in place.
