Sorry, it seems like that computer can only accept DDR RAM which has 180 pins on the chip and not DDR2 which has 240pins on its chips.

DDR memory standards are not backwards compatible. DDR2 or DDR3 will not work on a DDR motherboard. You need DDR-400 (PC3200), Your motherboard has a 4GB limit and has four slots, this means you need four 1Gb sticks. To get this amount, you can purchase two 2GB (2 x 1GB) RAM kits, like the WINTEC 2GB (2 x 1GB) 184-Pin DDR SDRAM DDR 400 (PC 3200). Note that unless you have a 64-bit operating system, you will be limited to about 3GB of installed memory since 1GB or more will be used for addressing on 32-bit operating systems.

According to the specs at HP, you can have 4GB with 1GB in each slot. The kit I linked to should work. Here are the specs for your PC.

Some PCs can work properly with high-density RAM while the vast majority of systems work properly with low-density RAM.

Ok thanks, i think in the article it said something about "As a rule of thumb it seems safest to assume that no Asus or Intel boards (with the exception of the 915) will work with High Density RAM."

I have "Chipset:Intel 915GV" so does that mean my computer is compatible with high density ram or not?

I don't understand your confusion since the table below lists what you need and comes directly from HP. Crucial also agrees with HP in suggesting PC3200.

Memory

Memory Installed: 512 MB (2 x 256)
Maximum allowed: 4.0 GB* (4 X 1 GB) requires the replacement of the installed 256 MB DIMMs. *Actual available memory may be less
Speed supported: PC3200 MB/sec
Type: 184 pin, DDR SDRAM
DIMM slots: Four
Open DIMM slots: Two

Its just that i wanted to know what kind of density my computer can handle High or Low density ram that's all. It doesn't say what density in the specs

ApInflux,
When replying to a post, don't use the QUOTE button under the post, unless there is something specific in the post, that you want to quote.
Either use the button at the top of the page labeled Add Reply, or one of the 2 buttons at the bottom of the page, labeled Fast Reply, and Add Reply.
It keeps from cluttering up the board with unnecessary quotes. :thumbsup:
