Possibly folks out there can help me in a "not too technical" way.
I have acquired an HP 9870 Pavilion from a friend. I am hoping to use this for Digital applications, Photography, Movies, hey and a couple of big processor/memory eating games. Have been searching information about upgrading the memory. Have found conflicting or confusing information regarding Rambus Memory for this machine and how much the motherboard will hold. Have found information stating it will take 2GB and other information only 1 GB (both from HP. go figure). Current installed memory Stick Info: PC600 RAmbus 64MB/4d nonECC, there are two. HP Documentations states these are 400MHz and the HP specs on the motherboard show the memory channels are 16/18bit, Dual Channel RDRAM.
Would like to run 800 Mhz or more if I can, but will the board support it. I do understand that the memory has to be added in pairs, but which pair...RIMMA1 and RIMMA2 for RIMMA1 and RIMMB3. Current Configuration: (RIMMA1 - 64MB) (RIMMA2 -CRIMM) (RIMMB1 - 64MB) (RIMMB2 - CRIMM) I know the CRIMM are dummies and just fill the socket and close the memory circuit. Does it matter where the CRIMMS ARE? If this is a dual channel?Which two consists of a channel. Would like to add 2 512MB Sticks and utilize the 64MB sticks as well if it's possible. Unlike SDRAM I know this works a little differently.
I would like to find used memory on Ebay to keep costs down....What should I look for that will work on my board. Had my eye on Some Infineon 512 Memory PC800-40 Sticks...Cheap...but could not find any documentation to support whether or not they would work.
I would have to probably update my bios to incorporate higher mhz. But in trying to get into Bios on this machine, I have tried all the usual keys while booting up..Del, F1 and F2..I understand that Phoenix uses F2...Hasn't worked.
Computer Specs:
Motherboard: Asus P4T Alcatraz (would have to open the machine to physically investigate the version number on the board)
Chipset: Intel i850LE 1300 MHz Pentium 4
Current RDRAM 128
Slots: 4 - 64MB in two of the slots.....in the other 2 slots
