Adding to dual-channel RAM

Hey there. Just wanted to know, if I have 2gb ddr2 800 installed (in 2x 1 gb sticks) and I add a ddr2 533 1g stick, will it be worth it? I assume the 3gb total will then run in 533 and no longer be dual channel. Is 1gb extra RAM worth it?

Extra Information:

I have a BIOSTAR A770 A2G+ m/b with Kingston ValueRAM CL5 1.8v memory.

Typically dual channel does not provide as siginificate a gain as the total quantity of memory. I would suggest installing the ddr2 533 and trying to oc this to get a bit faster. You may however see a bit slower response as there is a difference between the 800 and 533. Do you use many memory intensive programs?

Nah mostly gaming, unless that is memory intensive. Its a home pc, so memory intensive is winrar'ing and running antivirus i guess. I oc my cpu (athlon 7750 BE so i just up'd the multiplier) but dont generally touch the memory or latency settings. but i might give it a try, as now I have a reason to up the FSB.

Hi.

U are right in the speed, all the RAM will run at 533MHz, but only ONE of the sticks will run in single channel, the 2x1GB will run in dual channel.

Performance increase? maybe not.
