problems Overclocking 1.8A Northwood

[nikko]

I have a 1.8A Northwood that I have been running at 2.4 gHZ for a while. I added a couple of components and this led to some airflow problems, which consequently led to over-heating problems. So I knocked it back down to 1.8 gHZ until I got some cooling solutions, which I now have. So this morning, I try to overclock it and I do it the same way I always have - by going into the CMOS and upping the FSB from 100 to 133. I saved and exited, as I always do. But for some reason, when it reboots, it won't read the FSB as anything other than 100. I thought maybe I just hadn't saved the settings the first time, but I went through this several times. Everytime I would change the FSB from 100 to 133, and everytime when it posts it would recognize it as have a 100 FSB. Any ideas on what gives? I'm truly stumped. This has always been the way I've done it and it's not like it's so many steps that I might have forgotten one. For what it's worth, I'm running WinXP on an Alabatron PX845PEV Pro 845PE. Any suggestions would be much appreciated.

maybe try to go in increments of 3-5 mhz? I have the same board and proc, I incremented and got it up to 150 FSB. What is your ram divider set at?

Change your cpu voltage to 1.6. Try leaving your ddram setting at default and see if your system boots at 333 for ddram speed, if you have pc2700. Otherwise, try the various settings (2.0, 2.5, etc) until you get the desired speed. If your system won't post, hold down the "insert" key when rebooting and the system should post at the default settings, or use the cmos jumper to reset the bios.
