On dual board, can three RAM sticks run faster than two? Or do I leave out the third stick?

I'm trying to set up my mom's computer during my visit, before I leave. Any help appreciated!!

I have three sticks. 256 that came with computer, and two identical 1G (that are correct for this computer).

If I put in the 1Gs into color matching slots, can I add the 256 & get a slight increase in memory speed? Or does the single 256 make the whole system drop down to 256 speed, inclluding the 1G sticks? It's an HP Pavilion desktop a1220n.

If I can use all three, these are the slots. Which slots should I put which stick into?
A1 - black (closest to processor & fan)
A2 - blue
space
B1 - black
B2 - blue

Thanks!!

Best solution

Just leave the two identical sticks in. Adding the extra won't help it run any faster (probably hinder speed), and I doubt it is worth the extra space (not that it is a lot of extra).

i got through to kingston tech support. They said the same. Put the 1Gs in the color matched slots. I can add the 256, & it won't get used by the processor unless I've completely hit load limit, and then it doesn't help at only 256. It will run as an extra stick, not as dual, but the 1Gs will run as dual. The 256 will not hinder the 1Gs.

Oh good. Glad I was of some assistance :p 

Yeah, I guess if you have it there, you may as well add it in. (As long as they are in the correct slots for dual channel).
