Have recently purchased 3 of these (2 for friends).
They hit 2.1G stable with 0.05V overvolt!
Can't beat that price! They come in retail box with HSF.
I got them from www.it-rite.com
Oh and in my epox 8KHA+ the multi is partially unlocked. I can drop the multiplier!
2.1GHz XP1700 TbredB cores AU$115 with cooler
I just got a XP1700+ T-Bred from NewEgg the other day for $ 42 shipped. Thats the same chip that I am running right now (I got the second one for a spare), and it is unlocked and defaults to 1.60 volts. Right now I am running at 12x153 for 1.836Gig on a Abit KG-7 RAID board with 2x256 Crucial sticks of PC2100 DDR and it runs very cool and stable. Can't beat the price at NewEgg.
