Windows2000 Stop errors past 125mhz FSB

[BlakeM]

Hey guys,
Could be a newbie question, but whatever. I'm overclocking an Athlon 900 and have it at 1101.37mhz right now. My VCore voltage is shown to be 1.91, my CPU is running at 34 C(Swiftech MC-462a) at 122.37 FSB. Everytime I try to push it above what it's at now, I get STOP errors on Win2k and VFat errors on WinME. I'm running my PCI @ 36mhz and I believe my PCI voltage is 3.50.(not sure on the first digit, but it's x.5). I've got an ABit KT7A, SB Live! Value OEM, two DIMMS of Crucial PC133, 256MB each, an IBM 75GXP 30gb ATA/100 HD, a Linksys Etherfast 10/100 NIC and an Enermax 431w power supply. That's about all I can think of, any ideas?

Yes, the CPU/memory/PCI/AGP can't handle the higher FSB. You might try increasing the CPU voltage a bit, but you may have reached the ceiling on that overclock.

Yeah, I oc'd a Cele 800/100 Getting 960/122 with bios at 222 5/7 timing Cas2 Sdrams. Went to 133fsb which set 1070 and 44pci and crashed. Want 133fsb, so don't know if i can change the multiplier to 4 in bios to get the pci down to <40.
GigaByte has a neat oc pgm that adjusts all but the FSB that you dial in.
Got up to 1070/133 but did not last long. Had to back down to 960/122 which should which will run at 40 pci, (Gigabyte 60xm7e mobo). EasyTuneIII is the addon bios utility that allows you to oc from Windows without having to reboot. You can try different settings and then lock in. Have not really run and used this setting for any lenghth of time yet.

How are you able to run your PCI at 36mhz? I thought PCI runs at 1/3 of FSB?
Which in your case, 122/3= 40.6?

Supersix is correct. U have reached the ceiling of speed w/ ur currect spec.

Ur 36 Mhz on PCI is also not correct @ 122 FSB. U can't get 36 Mhz w/ either a 1/3 or 1/4 PCI divider. Did u make a mistake here ?

The ABit board gives me an option to get my PCI/FSB clock, and then adjust the CPU FSB in incrememnts of one, which I've done. I have a 108/36 FSB and added 16 mhz to my CPU FSB.

Just a long shot but try jumping straight to 133 FSB that will put the PCI divider down to give you 37 is it? PCI Bus
