Hi!
I'm planning to assemble a new machine for myself, curently with the following components :
AMD Phenom X3 720BE
Asus M3A78-T (790GX+750SB)
Sapphire HD 4870 512MB DDR5

Now, I'm really confused about the memory....I have two options :

OCZ 4gigs DDR3 - 1333Mhz
OCZ 4gigs DDR2 - 1066Mhz

I've tried but I'm not able to figure out whether above mentioned config, esp the motherboard would support 1333DDR3 or not.Could you please help me out on this?

The m3a78-t isnt compatible with ddr3 :(  but its still a good board.

In that case, what makes more sense ; going for DDR2 ram or changing the board? If the latter, could you please suggest me a board?

I would like this machine to stay with me for the next year and a half...I hope the DDR2 Ram doesn't become obsolete any time soon....

well if u want to get a board that allows ddr3 then u are most likely going to have to change your cpu as well... as far as i know most ddr3 boards are set up for AM3 sockets and im not sure if they are backward compatible. I would just get some DDR2 ram with good timings and u should be fine.

So, I'll go for the DDR2 RAM then.....thanks a million!!

actually i just looked at your proc and it is an AM3 cpu so you would be ok with getting a new board if u are really wanting ddr3. but you will be looking at spending at least $300 if you are wanting a decent upgrade versus $50 for some quick ddr2 ram for the motherboard u already have...just depends on how fat your wallet is i guess :)

I guess i'm currently happy with the DDR2 option (read: my wallet is not fat)..lol!

Thanks for the help!
Yes, even I would like to go for an AM3 motherboard, but those boards are all $300 onwards. I cannot spend that much on the board. If there are some economical AM3 boards available, please guide me.
I also have a doubt about my current board : The Asus Asus M3A78 board has two variants, M3A78-T and M3A78-EM. There's a big price difference between the two but not much difference in the features. Are they inter-changeable?
