|If you want to try using the same XP installation with the new mboard|

As far as the Windows installation on the hard drive of the old machine is concerned,
and the other info in that.
Running ram in dual channel mode is just another one of those things that is much better in theory than it tuns out to be in real life. You only benefit from it if you have programs that benefit from it's higher max data transfer rate, and most of those programs other than possibly recent games are not programs people have installed on their computers.
It's not the ram itself that determines whether identical pairs of modules of it can be run in dual channel mode, it's the capability of the main chipset's memory controller, or on newer mboards, the capability of the cpu's built in memory controller.
The number one bottleneck of modern computers is the max data transfer speed of the hard drive that you have the Windows partition installed on.
No matter which ram modules or cpu you install, your mboard will perform MUCH better than your previous one did.
Your mboard is an OEM only model. It's made by Asus only for brand name system builders - there is no support for it on the Asus web sites.
When you need to determine which ram you can use with it that is compatible with the mboard for sure, you use the HP make and model number to look up which ram is listed for it on ram manufacturer's or ram distributor's web sites.
You are better off not looking on the Kingston web site for that because they usually only list brand name system specific part numbers for brand name system models, and those part numbers are usually not available locally.
E.g. Go the the Crucial web site instead
Once you determine which ram module module part numbers are listed for your model / mboard, you can buy them from anywhere you like that has the same part numbers, and you can often buy those locally.
The 4gb virtual memory address limit for 32 bit operating systems.
An example of 3gb working better than 4gb in a 32 bit operating system.

jam's explanation refers to links on other sites:
Memory Limits for Windows Releases
You probably don't need 4gb.
How much memory do you really need?
As far as the cpus you can use with the mboard, HP has limited info about that in comparison to what is listed for retail mboard models.
HP often uses the same mboard for many of their models, and usually those models have more than one cpu speed / type of cpu - you can use the max cpu HP uses with all the models considered for sure, or any of the cpus they used with your model or other HP models that used the same mboard.
If you supply the specfic model number or Product number of your HP system, the HP part number of the mboard can be determined, and the HP part number of the mbord can be used to generate a list of all the models the mboard was used in, and you can use any of those model numbers to look up which cpus they use, and use any of those.
Scroll down a bit.
Find the similar label on the outside of the case.
- specific model number - at the end of the first line
- the Product Number - p/n - on the third line
If you search on the HP web site using the Product Number , don't use the # character or the characters after it to search with.
If want to try searching for the cpus it can use yourself...
Type in the specific model number, or the Product Number without the # and the characters after it, for your system.
Click on list all parts, scroll down to find the HP motherboard or system board number under PC boards
Copy that mboard part number, go to the top of the page, use that part number to search with.
Click on the line at the bottom of the resulting page to list all the HP models it is used in.
Use the part number of any of those models, without the # and the characters after it, to search with at the top of the page, on the resulting page have it list cpus or processors or similar.
