Ram Mixing Questions

post #1 of 4
Thread Starter 
Hello everyone!

I have currently 4x1gb PC 6400 800 mhz ram running at 4 4 4 12 timings and 2.1volts.

I want to upgrade to 8gb of 4x2gb PC 8500 1066 @ 2.2 volts and whatever timings they are.

My question is, if I buy only 2 of the 2gb 1066 mhz ram modules right now due to lack of money, can I mix it with 2 of the 1gb sticks of 800mhz I already own to make 6 gigs total by downclocking the 1066 to the same timings and whatnot of the 800 mhz? So, in theory having 2 different brands of DDR2 ram running at the same timings and volts (in this case making the 1066 into 800 @ 4 4 4 12) even though they are different at stock, to make a combined 6 gigs all at 800 mhz, dual channel, and 4 4 4 12 timings?

Eventually I would get the remaining 4 gigs of 1066 and run them all at that speed.

EDIT: And I want to make sure that they stay in dual channel as well!

ty guys in advance.

ya you can mix but stability for OC'ing goes out the window. I ran 2 different sets in my 939 system for years with no issues.

if you just buy 2 sticks of 2gb for now, they wont run in dual channel because the other sticks are only 1gb.
the 2gb sticks will downclock to 800mhz and you'll have single channel 6gb.

Are there no 4gb ddr2 sticks for sale in your area?
