Just did a successful update to my BH6 - ver 1.01. The slocket - slotket - SSA -(slot to socket adapter - Intel) was a problem. There are nothing but generic out there on Pricewatch, now. So, I got a generic from PCBAY.COM, $5 - quick UPS & $11 shipped, BTW.
It was not quite the generic unit shown on the website, but was the "Super Slotket III", said to be a problem. I was not at all optimistic. I noticed that about 10 .1uFD SMT caps were missing from the cavity inside the socket. ( most likely, for economy, not good)
Well, with bios updated to "SS" , I plugged it in, and to my amazement, the BH6 reported 901 MHz. Whoopee!
I reduced the voltage to 1.6 volts. (forgot it was SPEC'd for 1.75v) and I have since, reduced it to ONE POINT THREE FIVE 1.35 volts (1,35 in German) and it is rock solid! Must have lucked out with a good chip, it is a step 10, FWIW .( steppings used to be a big deal) The heatsink is ice cold - well, ambient + 10F max.
Anyway, I tried 3D with CFS. Shot down many bad guys. It was noticeably smoother with twice the CPU speed. A total success.
Except for one thing. I can't get the power supply back in the computer cabinet! (mid tower)
The Intel fan AND the slotket are a bit too tall to allow the power supply back in the original position. I will need to do some major surgery on the PS box to make it work, But, luckily, I am a whiz at sheet metal.

Still, I don't like to butcher things that might be avoided. To bad. A bit of work for .2 inches(5mm). A little lower slotket adapter AND a 60 mm after-market fan could, maybe have got by. In any case, the Intel retail fan is a bit large ~66mm to work even with a little lower slotket.
I'll have a weird one-of-a-kind power supply, but my beloved Abit BH6 will keep on cooking.
PS - As with the old 300/450 celly, my BH6 will NOT go even to 112 MHz FSB, no way. Dunno why, but I am pleased anyhow.
