Hello, I just asked about my hard drive when I saw this thread. My memory is next to be upgraded so I may as well do it the same time as the hard drive.This computer has been sitting for almost a year when the drive crashed and I miss it. It's a great computer with alot of bells and whistles even if it is old. I hate the thought of another computer in the computer trash heap of the world. So I'm trying to fix it myself. Thru this forum and HP I think I can do it.
I have a HP Media Center m1095.
Ram: 512 2x256
Max:4GB I have to replace the installed 256 DIMMS
Speed: PC3200 MB/sec
DIMM slot: 4 Open slots: 2
Can I go to the 800 speed with this.Says mx approved memory module 1GB and max approve memory is 4GB. It does say Front side bus 800MHz is this what I need for that speed? Hope I'm not taking on to much!! Thanks

You need PC3200 or DDR 400 memory. Add another pair of 2 x 512MB. No need to dump the old memory modules unless they will not boot with the new sticks. The newer DDR2 800 memory is not compatible with your PC. Unfortunately, older RAM will cost a lot more $.

Hi,one more question I'm alittle confused. I CAN add the 2 512's with the 2 256's that are already there OR do I have to get 4 512's Which means I will buy 2 of the 2packs at the link you sent me from Newegg. Sorry to sound so dumb but I was reading something about it will only run as fast as the slowest speed installed. Am I confusing that with the hard drive. (I'm trying to do this with 3 little kids running around UGH!)

Remove the two 256s and replace them with the two new 512s (same slots). Make sure the modules are fully seated into the motherboard. Reboot and check for problem. If okay, then shut down the PC and add the two old 256s to the other empty slots. Reboot. Hopefully, the old RAMs will run well alongside the new RAMs.
One of my rig runs WXP Pro very well with 1GB RAM. I don't think you will need more than 1GB! If you have the need to spend $, then order another memory kit if you cannot re-use the old 256 sticks. All of these modules are PC3200s, so there will not be any speed drop.
One other note. HP motherboards don't have an option to adjust memory timing. The default timing for a pair of PC3200 is 1T. If you add another pair (even the same identical matching kit), the PC may not boot unless you drop the timing to 2T. I don't think you can manually change this setting on your motherboard. The best case is that the motherboard will AUTO adjust the timing from 1T to 2T when it sees four sticks of RAM.
I think you will not see any problem with four sticks.

I have a HP Pavilion a6100y and want to upgrade the memory, right now it had 2gb and I want to go to 4gb. the HP site says max memory is 2 gb, but when I got the the manufacture website it says max is 4gb... I'm running windows vista 32bit. I would like to know for sure if I can upgrade before I spend the money.
