Ddr800 or 1066?

:hello: 
I just put the Phenom2 X4 940 into my Asus Crosshair. This setup does not like 4 sticks of RAM.
Last night I had to remove 2 sticks.
This leaves me with 2GB of DDR2 800 of OCZ platinum and the rig can only run at 800mhz max..
I would like to purchase 2 sticks of 2GB to run 4GB.
The retailers have 4GB packs of DDR2 800 for $130 and they have 4GB packs of DD2 1066 for $200.
1) Can I use the 1066 or is it a waste of money?
2) If I can use 1066 pack is it usefull for a future upgrade?
:sweat:

A bit confused. Were you trying to put RAM running at different frequencies into the board at the same time? The 940 may benefit a little from the 1066MHz, but what's the price difference? As for future upgrades, you'd probably want to use DDR3, so it's unlikely.

No! 2 sticks of dd2 800mhz or 2 sticks of ddr2 1066mhz.
Another forum said ram is backward compatible, but at au$70 extra per stick I wont do it.

Backwards compatible? What do you mean? It's not worth $70.

jbakerlent: 1066 ram can be used on an 800 mobo, but the mobo runs it at 800.

hollowtek: I will continue with two sticks of 800 as by the time I want more for newer games I'll probbably need a new mobo anyway.

Hi.

1- Yeah, Is a big waste of money.
2- No, isn't a good upgrade. A good upgrade is AM3 or DDR3 but not 800MHz to 1066MHz since the difference is less that 1%

So, safe ur money and build a new rig with AM3 and DDR3.
