Help please:I have barton 2500+ with msi kt4av motherbord and 512 mb ddr 400 ram
My multipiller is locked so i have to increase the fsb in order 2 overclock
I am only able 2 push it from 166 to 177
At 178 it is only stable for 3 â€" 10 min then restart
At 179 it will restart as soon as i get into windos
At 182 no boot
I tried increasing the voltage but it didnt help
I cant lock my agp/pci so i think this is the problem
Any suggestions

Ya, the PCI/AGP bus is the problem. One thing that might work is set the FSB to 200 because the Via chipset often resets the PCI and AGP busses there. But otherwise that's the limit that your system will sopport.

mobo may not entirly be the problem.
the barton cores realy dont oc all that well. it takes 1.85 core voltage to get my 3000+ barton to 2.4ghz, or 185fsb*x13, and it wont OC any higher w/o the same problems you get. any less voltage and it has problems at that setting.
you can try a newer mobo, but you very well may have the same problem.

Try to pick up a nforce 2 based board the best are the Abit nf7-s and the DFI. Most people can get about 2.2Ghz out of the 2500+.

The new ones can go to about 2.2Ghz by just uping the FSB. Mine is one of the old ones that has been abused (brother's girlfriend turned PC on without starting pump and left it running for the weekend and that's just the start of the abuse.)

Oh nforce 2 boards are around $100.

No not the mobile the regular ones. They have the locked multi and the slightly older ones that have the unlucked multi are even better.

About the boards the Abit is only 80 and there is a mobel of the DFI that is 75. Just look around.

Plus 100 bucks is pretty cheap for a quaility board when you consider that the cheapest boards cost 50-70.

what mem/fsb ratio it will runs depends completly on the ram, but it should.
here are the specs for it.
its official support only goes to 3000+ which depending on when they started making that mobo would have only been 333mhz FSB

Memory Speed/CPU FSB Support Matrix

i saw the link but when they say fsb 400 with ddr 400 in the chart Memory Speed/CPU FSB Support Matrix how is that supposed to work as the agp/pci speed is not locked?

how much do you want to up your barton?
i'm using same mobo and running 180 x 12

but don't try to push 200++ because that mobo cannot support that fsb.
try running sp2004 for an hour to verify that your clock is stable
