Will Opterons work in FX boards?

[Slaimus]

Seeing how the price of 100 series Opterons are much cheaper than the FX now, it would be great if they would work in a FX board like the SK8V. Has anyone tried?

It's works according to that list AMD has for AMD qualified Opteron boards.

Here's the list.

Here's Asus's CPU-support finder thing. I had it look for boards compatible with an Opteron 148 and it lists the SK8V, and also the SK8N with a 1004 BIOS or later. When in doubt, consult the board manufacturers' sites I've got a list of 'em here if you need it.

The 146 is the same as the FX51, and its price has dropped to $270 on newegg.

Gotta like that Are you ok with it needing Registered memory modules?

Right. The current breed of Athlon FX _are_ Opteron 1xx processors with a different label on. As long as we're on socket-940, Opteron's home base, of course Opterons will work. Registered DIMMs required.

IIRC, Opterons require registered ECC RAM where FXs only need registered (but work with registered ECC). There isn't much of a difference in price but make sure you get whatever your chip requires.

You can have non-ECC memory with Opterons just as well. The CPUs are identical! It's just that in the Opteron's target market, ECC memory is kind of a must, and the price delta isn't that much - after all, to go from a non-ECC DIMM to ECC just means one single extra DRAM chip per side.

Listen to him ^ He straightened me out on the whole Registered thing, and even found my on a different forum .

ECC Ram does not equal Registered ECC ram. and you need Registered ram for any socket 940 application.
