Well heres the deal... the Tbreds were the latest TbredA offering from AMD.... not the hot TbredB's ( when I say hot, I mean faster than all ****).
This is a low voltage TbredA, which means it runs cold, but still pretty nice. I have it running at 1730Mhz @ 1.65v and its cold. so I can make the rig quiet, and still carry some punch ( was at 2x 1.4Ghz Tbird before, now I am at 2x 2100+ speeds with what the mobo thinks are MP's)
Its nice since now I am using MP look alikes the Tyan board is happy as a clam to run them

Running Folding on them right now for a few hours to test the stability but so far it seems rock solid. and deffinitely has some more pep to it than tyan 1.4's
