Question What ram should i use?

[mathiasd.hauge]

I have 6 sticks of ram that i Can use.
What combo should i use? My mobo has 4 ram slots.

I have:
2 x 800mhz corsair 1GB ddr2
2 x 800mhz corsair 2GB ddr2
2 x 666mhz HP 2GB

I could use 8Gb but then the speed would be capped to 667mhz.

What should i use? For games...

I don't like and do not recommend mixing RAM that was not tested to work together, since there could be adverse consequences.

In your case I would go with the 8GB and sacrifice a bit of speed.
2 x 800mhz corsair 2GB ddr2
and
2 x 666mhz HP 2GB
See if it works.

Install the Corsair on A1 & B1 slots (1st & 3rd slots from the CPU)
