First off, I am having the same problems with an unlocked Duron 750 on my rev 1.2 KK266. Once I connected the L7's it will run at 1000MHz (yes!) at 1.85v, but when I try and adjust the multiplier it goes all over the place. When the FSB is set at 100MHz, the board will usually give me a multiplier of 8x or 5x no matter what I set in BIOS. At 133MHz FSB, the board will not POST no matter what multiplier I set - even though it runs fine at AUTOx133FSB=1000. I am using the conductive pen to connect the L1's, so I figure that is not the problem.
Has anyone RMA'ed the board to Iwill yet? Are they responsive? I have heard mixed reviews. It's too bad I ordered this more than 30 days ago from NewEgg, and had it sitting on my shelf until a few days ago.
On the plus side, 1000MHz with the TurkOC BIOS gives some impressive scores. I can run Prim95 all night without a problem, but it will barf after about 10 minutes of the Torture test. I guess I'll just mod the chip for a 7x multiplier and run at 133x7.0=933 for 100% stability. Hopefully, Iwill can get this right...
