From what I have learned,Phenom needs a + board to run right and also for using 1066 ram.

But do you think they will still fit on casual AM2 boards (not AM2+ ones).

well yeah but if you see sites like say ASUS board for like M2N-E, you'll see that it supports PHENOM but also stated 2000MT/s, AFAIK the X3 / X4 goes higher than 2000MT/s.

I'm just not familiar with Phenoms. So does that mean the processors would be forced to run at 2000MT/s?

Not sure. I don't mind if they are downclocked slightly, but I kinda curious that do people actually test a Phenom on a casual AM2 PC and see what happens?

CPU runs at 2600,if used on a am2 it steps down to 2000.

Then it's the fault of the motherboard manufacturer in not ensuring adequate power supply to the socket. The Phenom itself is compatible with the AM2 socket.

Lacus is trying to recall that a good portion of AM2 motherboards use only three-phase VRM (those mosphets around the cpu socket, count them, one.. a twoo.. a threee!)

The problem with this is that 3phase VRMS are unable to provide the 125watts that the biggest phenom needs to operate.

So make sure you're getting at least a 4 phase, more is better for efficiency.

Edit: for example:
TinyURL.com - shorten that long URL into a Tiny URL
those five little black box things !

TinyURL.com - shorten that long URL into a Tiny URL

this one only has a 3 phase, and they're old style mosphets to boot, lol!

Oh the VRM things... they are the most difficult when they have different processors on the same board.

Just like those boards which have older VRMs for S775 processors, they are just not compatible to any of the Core architecture processors. Older 945 boards couldn't, newer ones could.

Lacus · 21st May 2008, 09:11 PM

Lol, thanks for pointing that out..I'm not sure which mobo actually has more than 4 mosfet.. @goldfries, yeah i think it's something like that.
