overclocking a 366 to 550

[qsx]

I have a 366 cel with these number on it.
98511297-
SL376

I have a BE6 mobo with newest BIOS. With much tinkering I have finally been able to get it to boot @ 550mhz. But I had to crank the Voltage to 2.3 to get it to do it. I have a cooler from Net-n-Dude. My problem is the PC dies when it starts to try to detect an IDE device. I am using a the UDMA 66 interface on the mobo and I am wondering if this is causing a problem. Any ideas or pointers on where to go next, or do I need to forget it and go buy a newer 366?

Thanks

Try disabling quickboot in the bios as sometimes it doesn,t gice the bios enough time to detect the hard disk.

hey qsx,
good to hear from you man. There was a thread on this board about a month ago or so. People were complaining about BE6 boards. Apparently Abit BE6 board do not have a full ATA66 support, they say they do, but a lot of people said that they had a lot of problems with ATA66 HDs. Post a thread here and ask fellas who has BE6 boards about ATA66 support.

And do not be afraid to up the voltage a bit higher. I had my Cele running for 2 weeks strain at 2.8v.

Yes, I have an Abit BE6 w/ IBM ATA ultra/66 that cooks. Better then 100megs/s.

Haven't had any trouble with this M/B.

I'm also a proud owner of a celeron 366 and also running at 2.3 volts. How long is yours running at 2.3 volts?

Thanks All I will try disabling the Quick boot in the BIOS. ARN, that is the EXACT same setup I have what specificly did you change in the BIOS or do you just have a newer 366 than I. Let me know if you would?

Thanks

Still no luck, I am going to try moving the HD to the IDE 1 interface.

In your bios right below where your boot sequence is it says something to the effect (I am trying to remember without having to sign off and reboot)ah, here it is, "Boot sequence EXT means" make sure this says "SCSI". In the "boot squence" just above this make sure "ext" is in that statment (a, c, ext) for example. Doesn't have to be in this order just so "EXT is there somewhere.

Also plug your 80 pin cable into IDE-3 or IDE-4. I plugged my cd-rom into IDE-1. In the "standard cmos setup", I set to "auto" (primary master IDE-1) and the same for the (secondary master IDE-3). you can set the others to auto also if you have additional HDD's.

Does it boot ok and go into Windows when your cpu is set at 366 - 2.0 volts? If so then I would say it is your cpu.

Mine runs 550@2.0 volts. Currently at 568@2.1 volt. Dual fans on the cpu, intake fan at the bottom of the case and an exhuast
in the top. Temp at 35C up to 38C depending on how warm the house is.

I'll check back and see how it goes. Hope I can be of some help.
