Should work Ok as they do match. The confusion comes about with the freq setting. The new ram is advertised as 667mhz and your old ram shows freq of 333.4mhz. Looks like a mismatch but in reality they are the same. DDR means Double Data Rate which means the ram does double the work on each cycle. It runs at 333.4mhz but it performs like it was running at 667mhz and the chip makers like to use the faster number for marketing reasons. 667 just sounds better than 333.

A suggestion:
If adding the new RAM doesn't work properly, try setting the RAM timings and voltages manually in the BIOS settings. That may permit the chips to play together.
I hoped that you were mistaken, but I don't find any information about BIOS settinsg at www.hp.com. Dratted appliance PCs!
That's why I want a new MB, because mine is just uselessI don't have the money though, as I've just got enough to buy a 4870 from ebay
It should work, but you may have to manually set the timings and voltage in the Bios.
Its always best to keep all ram identical, but even different speed, latency, and voltage ram can be used together, if defined properly in the bios.
But no matter what ,since you aren't running identical make/model ram, there is no guarantee.
And any advice given is just an educated guess...
This is sound advice. Having 3gig of mismatched RAM installed WILL give worse performance than having 2gig of matched RAM.
And if you don't have access to the BIOS settings, you'd be well off with a matched pair of RAM sticks!!!
And as pointed out abouve, you also need to insure the voltages match.
Good luck.
I've just ordered the kit so I probably am going to just install them two and kick the other one out xD it should work fine as soon as i replace it right?
Well... if it's compatible with the motherboard, yes.
Good luck
