As the title says. When I bought the chip, I didn't notice that there were different versions.
look for a data sheet and check if the pinouts are the same, I doubt that they are but the T may just be a silicon revision.

MCP2 and MCP2-T are different variants of nforce2 southbridge, definitely not just different revisions. MCP2 is the most basic one, MCP2-T includes a few extra features. Most notably - SoundStorm, a couple of FireWire ports and extra LAN.
I am not sure how compatible they are and how realistic it would be to make different one work, but i'd definitely not just solder a different one and hope it works.

Didn't know how differentthey were, like you I wouldn't just go solering without doing research first
They're likely as similar as the bx and zx chipsets.
Ie, the same, but with bits disabled, and many "NC" (no connect) pins.
At face value, you might think great.
But all of those NC pins that you want to use on the better one need to be connected on the board in question.
Ie, even though the zx and bx are identical internally,and the pinouts are the same ex NCs you can't just drop a bx chip on a zx board and gain features the board never supported.

I would say they are pin compatible, if you look at Asus A7N8X and A7N8X-X, same pcb different southbridge, same as MSI K7N2 Delta-L and K7N2 Delta-ILSR.

I don't think he gives a damn about the extra features, just wants a working board.
The question is will letting the extra pins float and treating the IC as a direct replacement for its predecessor work?
