What will your machine cold boot to?

rdmpe · 02-11-2001, 02:11 PM

My 700E will cold boot to 973. I've had it up to 1015 stable so far, but can't boot after shutting down at that speed. This is such a dissapointing limitation! Is there a possibility that this can be addressed in a bios upgrade? I am worried it is hardware related and can't be fixed. If so, we could use a fsb utility if anyone can write one that works. I have only gotten lockups from the program "cpufsb" or whatever it's called. Supposed too support this mobo, but I can't get it to work on my cusl2-c.

So does anyone know the nature of this cold boot problem?

Thanks, and I hope this topic hasn't been beat to death recently, since the forums are pretty sparse after the switch. I'll go search the old ones if I can, that's next.

Don't worry, if it is a hardware proble then my board is f***ed as well.

I don't think the boot problem is overclcoking related as such, but rather that the voltage increases involved for a successful overclock is lost during the shutdown process.

Therefore, when you switch the machine back on again, the voltage increase you used to get your chip stable at x speed is no longer there to give the power that is required.

I have a similar problem, when using default voltage, I don't get a reboot problem, it is only when I oc and increase vcore at the same time that it occurs.

I personally think it is a biops problem but I may be wrong.

You should email asus about it, and if enough people do so, they may address it at the next bios update.

Im Running a 700E cCO stepping and it cold boots at 1 ghz. I will soon be post what i have done on the cooling forum.

jian · 02-11-2001, 11:42 PM

Killroy, is that at default voltage?

KillRoy · 02-11-2001, 11:45 PM

Sorry about that its at 1.70.

Hi guy's , i gues the cold boot problem is very much unpredicteble , i can cold boot up to 1100mhz . One notch higher and there it is !! I know i am lucky to boot at all at that speed but i just post to let you see how strande a problem it is , why does it happens at different speeds and not at just one speed as you would expect from a hardware problem??
Anyway i will adres this at Asus to so that's 1 more complaint!!!!

garnet_abx · 02-20-2001, 08:12 PM

Everything I've read on this forum points to a CPU limitation. You can't blame the mobo unless you feel it should boot at whatever speed you set the cpu in the bios. Well, I guess perhaps that's exactly what it should do! As jian points out it's the voltage required to run your chip at high speeds, that you don't realize when cold booting. It appears your chip won't startup at more that 973mhz at default voltage without going to the wire trick! Perhaps you've tried that.
I've cold booted my 700cbo at 1029, 1.8v. I haven't tried higher. I like running it a little below max.

Hey Heavenly, I like your new signature.

A CPU might need 1.80 or 1.85 to run 100% stable ,but it might only need default voltage to boot,and thats why you can Cold Boot at very high speeds ,but once you reach a speed that needs more than default voltage to boot you will end up in the bios having to do the trick.Its simple imagine a CPU that can run 100% stable at 1.85 ,that same CPU might be able to even boot into windows at default voltage ,but it will not be stable ,but in the Cold Boot process the CPU only boots at default until it reaches post ,so if a CPU can run at 1.85 most likely it will be able to Cold Boot at its default voltage ,but once you raise the FSB just a little more and you end up having to raise the voltage your chances of Cold Booting will decrease because the more voltage your CPU needs to run 100% stable the lower your chances are of being able to Cold Boot.By the way the voltages I wrote were just examples ,its the point I'm trying to make that matters.

Well I got you all beat.
I don't overclock, as I don't see a need to.

I have a PIII 800EB 133FSB and sometimes it won't cold boot at its rated speed.

I have to unplug the power connector and then plug it back in and reboot.

Funny thing is that I had tried overclocking the CPU before, and thats when the problem started. Now running at the rated speed the cold boot problem is evident.

The same thing happened to my PIII 650 slot I 100Mhx FSB on the Asus P3BF.

The problem began after I dabbled with over clocking and voltage changes to the CPU.

I think what this is telling me, is that I have damaged my CPU's by appling higher voltages.

But once they are running, they run for weeks at a time.

My cold boot problem is exibited by the following scenario.

I can here the drives spinning up, but the POST screen never happens, the Monitor never comes out of sleep mode and the First single POST beep never occurs.

hi DaveM
It looks like you might have a powersupply problem because you have to unplug it and plugin before you can boot , i once had the same problem and a new ps fixed that , maybe try a friends ps ??

Asha_abx · 02-21-2001, 10:30 AM

After the lapping I did yesterday I thought lets try to get a little higher. I was on cel600@1008 at 1.75v.
Now in little steps I am at 1062 @ 1.95v. It still cold boots to this speed. When I build up courage I ll try to get higher. The temps under full load still max out at 42c.

grtz Asha

by the way shouldnt this treat be under overclocking?

eddie_abx · 02-21-2001, 11:16 AM

Wow a Celey that's just like mine .My max stable speed is 600@1080 2.0 CCO.I can even go over 1100 ,but not for more than a few minutes.
