Grrr...processor upgrade frustration

The story so far........

I'm trying to squeeze another year of life out of my ancient box with the venerable ECS K7S5A motherboard.
I found a dirt cheap Athlon XP 2200 to replace the 1.2 T-Bird that's been running in it the past 3 years. Swapped the processor and did what I thought was the necessary BIOS upgrade. Set the processor speed to 133/133, and..........nothing. It recognized it correctly as a 2200, did the memory check and found all the drives, then stopped dead cold. Strike one!

Just out of curiosity, I fired it up again, but loaded the default BIOS settings using the 100/100 speed setting. It recognized the processor as an XP 1500.......but it started right up and ran perfectly. So my next thought is, let's try another BIOS. I've tried 4 different BIOS versions with this board, all with the same result; runs perfectly at 100/100, but stops dead at 133/133 (BTW, it always ran perfectly at 133/133 with the old T-bird). Strike two!

The first 3 BIOS versions I tried were "official" ECS versions; the last was the Honey-X overclockers BIOS (even though I have no designs on overclocking this beast). So I tried bumping up the clock speed a touch at a time. I can get it to 124/124 (equalling an XP 2000), and that's as far as she goes.

So what's everyone's thoughts here? Do I have a bogus processor, a cooling issue, or something else I'm completely missing? This thing's driving me nuts!

Just thought of something else to add.....using PC2100 (266) DDR memory. I know some people have had difficulties with this board using PC133, but that's not the case here.

I haven't touched any of the memory timing settings (left the defaults).....should I change them?

As long as it's set to use spd, you should be fine on that. Is there any option in bios to set pci/agp clocks or dividers? Im not too familiar with k7s5a's.

I had a problem with my old viakt133a based motherboard. For me the problem was that there was two versions of 2100+. One based on .18 core and one based on 0.13, unfortunately my motherboard only supported the 0.18 core. So I had to buy a nForce2 board and 1Gb ram to get it working :p

The symptoms was similar to yours.

Hmmmmm...... I have 2 256MB sticks of PC2100 in right now, but they're different brands. I might pull one at a time and see what happens. Both sticks worked fine with the old T-bird; are the Athlon XP's more 'sensitive' when it comes to memory quality?
