"Clocked and Locked"??

[novice]

I have been running my MSI-6309 at 124 Mhz front side bus pretty much since I built it almost a year ago, so my PIII 600E acts like a PIII 750. Pretty nice. However recently I have experienced some crashing in UT and some other applications, so I thought I would reset to default to see if it would help. Went into setup and set CPU Host/PCI clock to default, saved and exited setup. No post!! Tried other manual settings, nothing doing! Annoyed with myself, in desperation, reset to 124, which then booted windows just fine. I am very puzzled. Any ideas? Should I try to reset CMOS? I don't want to lose my system or have to reformat and reinstall if I don't have to, but I would like to have my choice of settings restored. Also, I am still running the original BIOS that came with the board, ver. 1.0 And I am sure that there are new and improved BIOS's available, but flashing scares me, as I am not DOS friendly at all and again, I don't want to mess up a working PC. Appreciate any input. Thanks in advance. Chuck

Anybody? I will probably just keep running at 744, since it has been very stable, it just bugs me that I can't adjust the front side bus like I could before. I still love the MSI-6309 board, and just put one together for a friend with a Celeron 633. So far (1 week) it is working great.

This probably won't help any, but just letting you know that I had an old P233MMX a few years ago that I have "overclocked" to 225 Mhz but with 75Mhz FSB instead of the old 66Mhz. Back then with the socket7 the L2 cache was on the board so overclocking the FSB made a huge difference.

Anyway when I switched cases I decided to just run it at the default 233Mhz/66Mhz FSB. No OS would install on it when I did that and it was extremely unstable. Putting it back to 75Mhz FSB seemed to fix things.

I haven't heard of any recent hardware get burned in to a certain overclock though. I'd try resetting the CMOS/BIOS defaults, etc and see if that helps.

Good luck!

Thanks for the reply, gaidin123. So it is possible for a CPU to "burn in" at the higher fsb, and then be unable to be run at different front side bus speeds? Would it be advisable then, to periodically reset the front side bus to default and run for awhile? I currently have a Celeron 600 running at 900 on an identical MSI-6309 board (well, not quite identical, it has a newer BIOS) and thought maybe I should run it default for a while. Appreciate any other comments. Thanks in advance,
