I have an ASUS P5A-B rev 1.04 and have an AMD K6-2 500mhz processor on it The post says I have a 550MHZ on it. I have checked all jumpers and they are set for an AMD K6-2 500mhz. See the pictures below for my jumper settings. Who knows what's going wrong here
Until a few years into this century, a motherboard could only tell the core generation of a CPU, not exact model and pretty much guesses the speed from timing loops at boot. So nothing much wrong per se, though it might be right-er with a later BIOS.
Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.
the latest version of the bios is on it 1011.005
That certainly looks like it's jumpered for 5.0x multiplier (BF0 to 1-2, BF1 and 2 to 2-3) and 100MHz FSB (FS0-2 on 1-2, FS3 on 2-3). You're also running the latest BIOS, so it's not a lack of K6-2 support on that side...
So, one of three options:
- BIOS isn't measuring correctly.
- BF1 is somehow shorting 1-2 instead of 2-3, leading to 5.5x multiplier.
- FS0, 1 and 3 are all doing opposite of how they are jumpered, leading to 110MHz FSB.
I'd suggest changing multiplier, then FSB and looking at what happens:
- change multiplier from 5.0x to 4.5x (move BF0 from 1-2 to 2-3) and see what BIOS says. If it still says 550MHz, it's not certain yet. If you get 400MHz, BF1 is somehow stuck on 1-2. If you get 495Mhz, you're somehow on 110MHz FSB or BIOS has a consistent measuring issue.
- with multiplier still on 4.5x, change FSB from 100MHz to 95MHz (move FS0 from 1-2 to 2-3) and see what BIOS says. If it *still* says 550MHz, BIOS is just messing around. If you get 380MHz, that's confirmed measurement is correct and BF1 is stuck on 1-2. If you get 427.5MHz, BIOS is measuring incorrrectly, but at least doing so consistently, and if you still get 495MHz, FSB is stuck on 110MHz somehow.
If the timing crystal and FSB reference crystal are two different crystals then one might be out of spec WRT to the other.

Have you checked with something like CPU-Z in Windows?
After watching many YouTube videos about older computer hardware, YouTube began recommending videos about trains - are they trying to tell me something?
