Hi Guys!
Just an easy question for you:
Can a DDR3 1066mhz memory run with a CPU E2180, which only has 800mhz of FSB?
 
I'm buying a new system, and I'm going to spend hard on the MB (Asus P5E3), thus saving some bucks on the CPU*, so next year I upgrade it along with the memory. The cheapeast - hence slowest - memory compatible with the MB is the 1066 DDR3, which runs faster than the CPU, which made me wonder if it's going to be stable.
 
 
I know you geniuses know the answer!
 
Thanks in advance,
Francisco, from Buenos Aires ARG.
 
* Take in consideration that in the place I live, a 6300 costs nearly double the price of E2180...

Yes it is compatible.  However, there's no real benefit to going with DDR3 over DDR2 and benchmarks support this.  I'd save the money and get good DDR2 800 that you can overclock well.  On the mobo, you'd be served well by Asus (my mobo brand of choice too) with:

No use paying the huge premium on DDR3.  Once DDR3 is actually needed/gains traction in mainstream, it's prices will drop like mad, just like DDR2 did.
 
You'll end up paying the same amount in the end; 300$ right now for DDR3 or 150$ for DDR2 & 150$ for DDR3 in the future is the same (monetary values are examples!), but you'll at least be able to get some money back on the DDR2 is you sell it used in 1+ year.

And sadly... the Socket 775 is dead anyway after this year, because nehalem will change sockets completely. If you're to spend on a new system now then use DDR2 800 and an affordable, but good motherboard (GA-P35-DS3L comes to mind).

Great inputs guys! Regarding the compatibility of the CPU with the chipset, I found this Intel´s resource helpful (in case anyone else needs some)

I believe though I may need some BIOS change, since I saw in the first sticky post of this forum that the Core2 Duo use diff voltages.
 
Regarding DDR3 vs DDR2, just one question: Would DDR3 be your choice if you're thinking to spend your money 50% this year &  %50 next year on your system? I was thinking that DDR3 was gonna kick DDR2 out with some 1600mhz frequencies soon.
 
Cheers!

1 year in "computer space & time" is huge.  I wouldn't base any build on money a bit here, and money 1 years later, the technology & prices might change way too much that the build won't make sense anymore.
 
If I was in the midst of buying a new system, the only thing I'd wait on it the video card, the rest (CPU/mobo/RAM/HD/etc...) I'd buy in the here and now, with hardware that's considered the best bang for the buck.
 
I still wouldn't touch DDR3, just like I wouldn't touch any extreme edition CPUs (lol 1k+ for a CPU?!).  And chances are, DDR3 will have changed within the next 12 months, maybe they'll be able to get much better timings than they have now.

Thanks once again. I'll take a look at the prices and let u know what I got.
