PII 450 running at 300?!

[ackbar]

I just bought a PII 450 online for my father. He previously had a 300mhz celeron. His motherboard is an amptron PII-2300. He installed it and when it boots, it says that it is a PentiumII with 512k cache, but only running at 300 mhz. The motherboard has jumperless cpu settings. Is there something that he should be doing that he is not? Unfortunately, I am at college and he is at home, so I have limited information. The gist of it is that it runs fine, but is not at the supposed speed. Does anyone have any suggestions, or have the same kind of motherboard and know what to do?

Thanks in advance

He has to change the FSB from 66 MHz to 100 MHz. Right now it's set up for the Celeron:

4.5 x 66 MHz = 300 MHz

He needs it to be:

4.5 x 100 MHz = 450 MHz

And he wants it to be:

4.5 x 133 MHz = 600 MHz............=)

Just as a goof, while I was playing w/ my P/// 600E the other day, I set the FSB to 66 MHz....

P/// 400's get REALLY LOW benchmark scores in Sandra... DOH!!

Ran very cool at that setting, though. hehehe

I believe the Amptrom PII-2300 is an LX chipset board which will only run 66Mhz FSB. I could be wrong but if my failing memory serves me, I believe that's the case.

I do believe you are correct, sir. Good point.

Surer than heck ain't agonna get 133 FSB......(on that mb)

You are correct, I just found that out (after attempting to update bios and failing). Unfortunately, the dang thing decided to reboot by itself in the middle of the update. It now freezes at something like "checking VRAM" on the bootup screen. So now my question is, what kind of motherboard can I get that can use the PII 450 and support PIIIs in the future? I also notice i'm going to need to buy different ram. Turns out this is going to cost a lot more than originally intended.

Oh yeah, almost forgot. Is there any way to get the BIOS back to normal without using the mobo? My uncle has the exact motherboard and fortunately, he didn't attempt to update his BIOS yet. The board would still be usable if I could get the BIOS installed properly. Can I do that using a ROM programmer or something? Or maybe something called a hotswap? How much of a risk is that?

Good Lord, there's more motherboards out there than there's room to list. Here's a few good ones;

Abit BE6 II, BF6

Soyo 6BA+IV or +100

Well, there's four really good ones quicker than you can say "Ticonderoga", (if you can say Ticonderoga......apologies to Curly Howard).

I'd stick with an intel BX chipset based board, very good track record for overclocking.

Get a good board and PC133 ram, and set your sights on 600 MHz.

Good luck. (watch those temps....)
