| Well, the good news is that my K6-III+ is running without a hitch in the IA-1. I changed the FSB to 100Mhz using the jumper resistors. (It took an hour, a magnifying glass and a bunch of patience). After getting a successfull boot of the IA-1 (I'm on it now), I decided to try the multiplier. I noticed that it was already set to 4.0x - but the BIOS reported a 300MHz processor at 100MHz FSB. What gives? Since I only had to change one jumper to test this, I chose to bump it up to 4.5x. Well, sure enough, now the BIOS reports a 350MHz processor with a 100MHz FSB.
Now, I'm not unhappy - the IA-1 is a *LOT* snappier at these settings. Best of all, the K6-III+ mobile processor is running very cool, and it looks like I won't need a fan - but what's the deal? Anyone have any ideas?
I would try to change it to 5.5x, to get 4.5x, since the K6-III+ I have is a 450MHz part, but now that there is a multiplier setting tool for Linux, I may forgo this mod. I'm really scared of destroying the unit soldering and resoldering jumpers I can just barely resolve even *WITH* a magnifying glass. To get to 4.5x (or 5.5 on the unit) would now require changing nearly every jumper on the board. Besides, at 350MHz, the chip runs less hot than the 266MHz processor I just pulled out... | |
