XP2600+ (Barton) Settings

I just recently bought a new mobo and processor to replace my old Athlon 750(Pre Thoroughbred). I got a Soyo K7VME mobo and a a XP2600+(Barton) chip. I don't need a lot of speed and power as my wife mostly uses it for email and surfing, and I occasionally do some minor video editing on it.

For some reason, the processor is only running at 1150Mhz instead of 1900Mhz like it's supposed to. I went to set the jumpers on the mobo, but it doesn't have any. 0, nada, none. So I checked in cmos, and the only setting I have is the CPU frequency and a memory adjustment. These are my possible settings...

CPU Freq --> 100 - 132Mhz
Mem Freq --> CPU + {33, 66, 100}Mhz

Do any of you guru's out there have a clue what the correct settings might be?

I tried just adjusting the CPU Freq to 132Mhz, then it won't post. I've tried a couple of different combos, but when I get it wrong I have to short the cmos to get it to boot.

  1. Check the manual for jumper settings. Are you sure your motherboard supports 166FSB? Your chip is suppose to run at 11.5x166.

  2. Maybe a bios update's required?

  3. Are there any jumpers on your board to switch FSB settinsg? I know you said no...but check again.

  4. I had a similar problem with my old MB and an Athlon XP 1.7+
    Although the CPU was listed as supported, I found out after some thorough research on the net, that the MB had a known issue with that specific AXP 1.7+ TBred step B. All other CPU's were fine.. Of course, the MB company was denying what many people found out the hard way :wink:

  5. There should be another CPU bus setting in BIOS, perhaps it's called CPU/PCI ratio or something, that gives you adjustments in big steps (100, 133, 166).
