XP 1600+ won't do 133Mhz

[barofhumanreason]

ABIT KG7-RAID
Athlon XP 1600+
Kingston 256MB PC2100 DDR
W2K

On the Soft BIOS menu, when I select 1600 (100) option, it works fine, but when I do 1600 (133), it gives me an error message saying there's something wrong with one of my drivers. Any ideas?

Have you updated your BIOS recently? If not, try doing that.

I updated bios using one abit put out on 6/02. Can't do it.

Another note, it says on CPU ID programs that it's running at 1050 MHz.

1050mhz is the speed a 1600+ will start at on some boards (such as ECS K7S5A) and generally when you set to 133mhz fsb is goes up to the correct 1400mhz. When exactly are you getting the error message? Have you changed any other settings in the bios? What speed memory is installed?

Is it possible you need to change the CAS settings? Maybe look at changing from 2 to 2.5 - might well be an issue with what your memory can handle. Another thought would be to try incrementing it up to 133(if the board allows).. so try like 120, see how that performs and make adjustments from there.

Check the MoBo for a switch. Mine was on the lower right hand side of the board. I had to switch it to the correct setting to reconice my processor correctly. Check the MoBo Docs/book. BIOS change wont fix it.

Exactly, check the jumper settings. On my AOpen AX63-Pro for my P3 933 @ 1008, there are jumpers that depict what FSB I run at. For instance I use X jumper setting for FSB of 66-99, Setting Y for 100 to 133 and setting Z for 144 to 160 (or so, these are just rough numbers)

I tried tweaking the settings. I set multiplier to x10.5, CPU FSB Clock to 133Mhz, and FSB Rate (CPU: SDRAM: PCI) to 3:3:1.

This is the same as defaults for XP 1600+ CPU except that the ratio is 4:4:1. The computer boots with these settings. It does not boot with 4:4:1. It gets to when the baby blue screen for logon for W2k should appear and fails to boot. I had a drive on my computer that was formatted with FAT32, and it gave an error message saying something about a FASTFAT driver or something, and when I deleted that partition, it simply flashed a blue death screen and rebooted. Hmm....

The way I have it right now, the CPU ID program has it as 1400Mhz, 133Mhz BUS, which is what it should be. The ratio thing confuses me. Since CPU Bus speed is already defined, wouldn't 3:3:1 be faster than 4:4:1? Anyone know what that means?

Another thing. When I set it to x10.5 multiplier, 120Mhz Bus, 3:3:1 and run it, the CPU ID software identifies it as 1260Mhz, 133Mhz Bus speed, and 9.5x multiplier. ? x-( ?
