Windows 7 / XP * Anime = X
kureshii:
The memory controller is not on the E8500.
Kuroshima:
Yes it's on mobo.... But the data from CPU to memory is limited due to bandwidth...
Well... On 775 socket
kureshii:
Why're you talking about the memory controller on the E8500 then?
Be specific — what do you mean by "faster"? Higher clock speed? Or higher transfer bandwidth?
AMD's memory bus on their newer (Athlon II/Phenom II) processors have a higher theoretical maximum bandwidth than the Intel® 82P45 Memory Controller Hub (used on the P45 chipset). But the actual bandwidth available is often far lower than these numbers, and also depends on the speed of the DIMMs used.
Here's a synthetic Sisoft benchmark comparing some Phenom II and Core 2 memory bandwidths (too bad I couldn't find comparable Athlon II numbers):
And the corresponding latencies:

Not that this is any relevant since Windows doesn't explain how they do their WEI testing. It is naive to assume it is based solely on clock speed or transfer bandwidth.

How does the CD differentiate between 3 machines?
And by 3 machines, is it counted as 3 different hard drives (regardless of whether it was on the same motherboard or different motherboard)? Or any amount of hard drives as long as they were on the first 3 motherboards used?

The EULA allows you to install it on 3 machines. You can try and install it on more, but you can't activate it, or legally use it.

Someone say 32GB RAM ?
Server Mobos FTW
