Crucial and Kingston are not much help. Try contacting these guys:
I have an HP Pavillion xt966 1.3 P4 256mb Windows Me in which I want to upgrade to 512mb of ram. I am not sure what to look for or if it is possible to upgrade this computer. Here are the specs for the memory.
256 MB PC600 Rambus (RDRAM)
2 GB (4 x 512 MB RIMM) (MS Windows Me supports up to 512 MB)
400 MHz synchronous
4 / 184-pin RIMMs
128, 144, 256, 512 MB RIMMs
Yes. Rambus RIMM modules must be installed in pairs, and both modules within a channel must be identical (same manufacturer and type).
If there is an unpopulated RIMM socket (in a channel), it must be loaded with a C-RIMM (continuity module) to complete the Rambus channel. For example, populate each channel with:
RIMM + RIMM or RIMM + C-RIMM
Free RIMM sockets
Intel PC600 RDRAM 400 MHz
NOTE: Free RIMM slots may vary due to availability of memory components at the time the PC is manufactured.

Any response would be appreciated. Please let me know what type of memory I need to buy. Thank You.
