PC100/133 SDRAM DIMMs, with maximum 128MB per slot in 2 memory slots. The HP Pavilion 9694C takes the PC100/133 SDRAM DIMMs Memory Type.

Hope that helps.

The maximum upgrade would be a 3.4 Ghz CPU, you would not see any difference in day to day use.
Your max memory is 4GB, if you are using 1GB or less, you would see a big difference upgrading to the max.
A hard drive upgrade may also see some benefits.
Some info for you here ...

I suggest you install an AGP video card that suits your requirements. If you play games that require a powerful graphics card, then I recommend the G Force range of graphics cards. A computer shop can recommend to you a graphics card depending upon what programs you are running on your computer. The games programs usually recommends a graphic card with their games.
Don't forget to disable/turn off the on-board graphics card in the BIOS if you use an external graphics card.

try the new memory one by one and the memory should be PC2 3200 MB/sec and DDR2 SDRAM and as there r 4 slots try diffrent slots also

I need color of the wires that are in question. since some wires are not used. please make sure that the hard drive and cd roms are all plugged in and especially the fans are what I am concerned with.

Memory Installed 512 MB (2 x 256) Maximum allowed 4 GB* (4 x 1GB) requires the replacement of the installed 256 MB DIMMs

Thats the sticks you need

Good luck

The motherboard will only recognize 256 module. If you go to crucial.com and run the memory test, it will tell you the maximum memory the motherboard will support. So buyin a higher memory stick is wasting your money since it will not support it.

the model SR1010NX can take upto 1gb max of ddr 1 ram and must be done a 2x 512 ddr 1 chips

These are the spec of memory you can use .
If it does work by itself it might be defective of not compatible with yous system.

its that 512 mb total capacity for your computer memory?? if so read this:
To find the total amount of RAM that can be added , subtract the amount of RAM currently in the computer from the maximum amount of memory the computer can hold. For example, a computer has 256 MB of RAM. If the maximum amount of memory the computer can hold is 512 MB, then 256 MB is the amount of RAM that can be added. this info from the HP website , to find out more , go to http://www.hp.com/support , enter the model number , and look for more information about your computer specs, hope this helps , please rate & thanks AJ
