AM3+ is backward compatible with the AM3, but Bulldozer is for AM3+ only

[qcmadness]

I know I have posted this exact text somewhere else, and I think I might have been replying to you:

AM3 boards support only AM3 processors
AM3+ boards support AM3 processors and AM3+ processors

There is no bios upgrade or other magic pixie dust that will change this.

To do bulldozer in AM3 sockets would have compromised the possible performance on the processor and I am pretty sure that none of you wanted that.

Then why didn't AMD make 800 series chipsets Socket AM3+ compatible?

JF- a lower end BD will still be better than Thuban.

Then why didn't AMD make 800 series chipsets Socket AM3+ compatible?

A. Since Bulldozer was still in development back then?

B. Their crystal ball broke?

C. They want to change socket every year like Intel?

I totally agree, but. .

That's a question I've been asking for a while.
The 800-series, C32 and G34 all showed up at the same time but only the two latter works with BD.

AMD knew what needed to be implemented in C32 and G34 to make them BD compatible, so IMO they could just as well have launched the AM3+ socket together with the 800-series this spring, but they didn't.
