The Pencil trick

I've got a T/bird 1.4 Ghz. Wanted to clock it. I tried he pencil trick on the L1 bridges to try and unlock the clock multiplier. I set it to 11x to check. It looked as though it worked as the bios said the cpu was running at 1466 mhz when I powered up. But when I got to the point where windows should have loaded then it just blue-screened...


Set it back to 10.5x. 1400mhz

Running fine now.

Specs:

t/Bird 1400mhz
256 DDR @ 266 (2100)
Gigabyte GA-7VAX




 
If it was indeed running at 1466 MHz, then yes, the trick was successful. However, if it bluescreened upon loading windows, then chances are the CPU simply cant take the stress. The 1.4 was the fastes TBird ever made, and also the hottest. AMD didnt dare clock thew TBird any higher because they knew 1.4 was the limit. There are a few 1.4s that can rfeach 1.6, but they are rare, and often water-cooled. Chances are your CPU is near the max, and the extra 66MHz was just too much for it.
 
your t-bird should be factory unlocked.. all t-birds 1.2GHz or higher are.

seems like your CPU doesn't OC well, i had around 2-4 1.33GHz t-birds, and all of them would run stable @ 1.466MHz with stock voltage, with 1.85V i could get them to run stable at 1.53GHz
 
Yeah, I think all Tbird 1.4s are already unlocked by default. Mine is as well. However, since my K7S5A doesn't have multiplier adjustments, I can only overclock it to 1.5GHz via FSB adjustments.
