Overclock limit
Specs below. Running Windows XP. I got the FSB at 225mhz, but when I try to go over, Windows won't start. As it stands now, mobo is at 39C and CPU is at 32C, so it's not the heat. And it withstood an hr of full load as it stands now so there isn't really any instability in the cores. I was wondering if XP has a clock limit? Or if there's another problem

Re: Overclock limit
Will it go through POST? If not, it's your vdroop. You need to up the voltage, but BE CAREFUL. If you have not dealt with voltages before, post your current voltage here and list the next step up for CPU voltage provided in your mobo's BIOS.
Also, the same for FSB voltage. Just post the number, and the next step up.

Re: Overclock limit
You should look at the CPU core temperatures and not just the CPU temperature. You're probably pumping more VCore than your motherboard can handle.

Re: Overclock limit
Vcore is 1.334. There isn't a next value. It lets me set my own and tells me by how much I should increase (.025 I think)

Re: Overclock limit
Try 1.35v...
If that isnt enough, 1.375. Small steps. You can bump the multi too. FSB usually hits a wall quickly unless you increase voltages on other components as well. (DONT DO THIS) If the fsb maxxes at 225, then lower it to 220, then start with the multiplier for higher OCs.

Re: Overclock limit
In my BIOS, I don't know where the FSB limits are. What would it be marked

The fsb being too high will cause other components to crash without increased voltage. Test it by putting multi at 10, then bumping till it cant boot then back off a few MHz.

Re: Overclock limit
It is. So, the cpu multiplier at 10?
