Boot at 1mhz?

hitbyaprkedcar7 · 08-01-06, 12:49 AM

I was just wondering... Has anyone, if its possible, tried booting there pc up at 1 mhz? Or some other redicilously low speed? Would it hurt the cpu or other hardware? Just a thought.. Would be funny to see a super pi 32m or 1m in it, lol.

lol i feel old. i remember wanting a 20mhz 286 because my 12mhz 286 was sluggish playing wing commander II.

you could try using a program like mo'slo to start up at a very low speed. i'm not certain but will dos work at 1mhz or does it require 4.77 (how could it know)?

Yeah, Apple II was a 1Mhz CPU. Then a more popular one the Macintosh was I believe less then 10Mhz, and the Apple III being around 2-4Mhz.

I had a nice IBM XT at 8Mhz. That's with Turbo on! That thing was a beast way back when

15Mhz Mac in my closet right now. Everything too, keyboard, mouse, and monitor. I wonder what it's worth? How about a Commodore Plus/4? 1.7Mhz MOS Technology 7501. I also have one of those mint in box.

I think the OP was asking about heavy underclocking rather then old pc's guys.
I have seen some underclocking done here on A64 but dont remember the results.

UnseenMenace · 08-01-06, 02:24 AM

im pretty certain that most current Operating Systems would not boot on 1mhz as such the best you could actually hope for would be a post screen.

Not that it would be desirable

Gnufsh · 08-01-06, 04:58 AM

Most modern CPUs/Boards would be hard. I think I can only go down to a 5x multi/100MHz FSB.

hitbyaprkedcar7 · 08-01-06, 01:11 PM

Yeah i was talking about more modern cpus

lol

Yeah.. i just remembered most boards can only get down to a certain multi/fsb/htt . Wasnt thinking all the way at 2am

IIRC the minimum frequency of A64's is 800MHZ, can't tell for sure tough.

Gautam · 08-01-06, 05:40 PM

I've run at 400 before on an A64. 4x100 IIRC, but lost the screenshot with my old ISP.
