How can I disable my BIOS from checking my CPU speed?

I'm running a Tualatin Celeron in an old BX board, and have hit an almost inevitable problem. When I overclock to 1.6Ghz, the board takes up to 4 minutes to POST, and at 1.7Ghz it will never complete it. It just hangs before it counts the memory.

It appears to be related to some BIOS settings also, as it will only boot at 1.6 when it is freshly flashed and I haven't entered CMOS setup.

I've done a lot of research, but there's just not enough information out there!

Thanks for any help :help:

    errrrrr...don't overclock, maybe? *calls for kyrsst!* jermz is too tired to think, damn thermo homework!

    plain and simple. if it won't post its not a stable OC.

    the only thing you could do is raise the voltage but make sure you have propor cooling. also your memory might be the problem but im not for sure since you didn't say any about your multiplyer or FSB.

    Yeah what SSR said don't OC. You can't tell your bios to not check your clock speed it will either detect it automatically or go by whatever settings you tell it to work at. In either case if you are OC'ing it and don't have everything set up right you will fry your chip or it will be unstable.

    TO OC a board you need to have your CPU and Memmory all running at compatible speeds and voltages. Then you have to have enough cooling to keep the bitch from fying. Not to mention your mobo actually has to be able to be able to support things running out of spec. Not all mobo's will play nicely when you OC them. The more you OC something the greater chance you have of damaging your CPU. What happens is when your CPU runs out of spec heat wise you potentially suffer data migration between the circut that will result in frying and closing off those circuts. Once that happens your CPU will start to actually slow down and eventually burn itself out.

    So ummm what speed is your CPU supposed to be anyway?

    It's meant to be 1.3Ghz. With a 100Mhz FSB.

    I have since run this little beauty in an i810 mobo (nasty OEM POS) at 1.7Ghz, it was a little unstable but that could be due to the 150W (yes, 150) PSU in that machine.

    It is perfectly stable at 1.6Ghz under stock voltage. It just takes a while to POST....

    How can I not overclock?? That's madness! Then it would be running at stock! I can't have that....

    P.S - I tried changing the chipset registers with Modbin (mostly out of curiosity), but it still wouldn't go past 1.6Ghz. Anyone know the register for In Order Queue Depth? Default is 8 and I want to take it down to 1 as apparently some people had to do that with BX boards and a Tualatin.

    That's not a real chip to be OC'ing the bus alone will limit the benifits big time. But whatever OC away

    Isn't the point of OCing to make a slow chip faster? Or do you only start with fast chips? :p

    i personally wouldn't even bother trying to overclock a celeron.

    imo its like trying to make a geo go fast.... the geos gets your from point A to point B pretty nicely but you really shouldn't put a turbo in it so it can go faster.

    in otherwords the celeron chip isn't the best thing to OC. do it if you feel its a must.

    SSR already sumed it up. Say you OC something by 10% if you base is slow a 10% increase isn't going to do spit. However on a fast machine a 10% increase is significant.

    You guys are obviously not going to help me.

    Not helping me because I use a celeron? Well I'm sorry.
    What happened to the real guys who help/know about BIOS's, like TMOD? Is he dead or something?

    Hmm... well thanks for taking prejudice against my rig. It feels nice to be part of a forum where people only help if your rig is up to their standards.

    I'll try somewhere else instead. Sorry I wasted your time with a Celeron.

    Snod, what these guys are trying to say, is that you are pushing your processor past the point where the bios can continue to work correctly. I/we don't thing that ANY bios mod will help you.

    The fact that it is a celeron is irrelevant! No piece of hardware is going to go past the point where the bios can't even read it any more, that is a CLEAR sign that you have done all that you will be able to do!

    Koudos to you for OC your system, but I, as well as the other people that have responded to your post, do not feel as tho you are going to be able to take that system any farther then you have. Sorry if that is not what you wanted to hear.

    Snod what do you want us to tell you? The miracle cure that will allow you to quadrouple your speed with an uber elite secret bios mod? You are doing things correctly but your system isn't working. YOUR system is telling you it can't handle what you are trying to force it to do. This isn't a point of us trying to act cool and point fingers at the guy with the celeron. We are just trying to save you time, and possible harm to your hardware.

    its not becuase you have a celeron that we're not helping. its becuase of what these guys said. you can only push equipment so far. once you get to your limit then your stuck there. the celeron has nothing to do with it. i may like AMD but it dosn't keep me from helping people with intels. i hear people talk all the time about how good celerons are. they're not the #1 processor out there but they can get the job done. and as said above there is no ub3r 1337 bios mod that will disable cpu checking. if the bios didn't check the cpu then how would the OS know what processor is being used? without knowing what the processor is it can't make the propor enhancements to boost the speed/effecientcy of the processor(IE-SSE, SSE2, 3DNOW) so i would just say be happy with your overclock. if you feel you want to spend the time waiting for it too boot then go for it. i can't stop you but there is no way to stop the bios from checking the cpu.

    Well, with no help from you guys, I found that the chipset register defaults in modbin were the key. I have since disabled ACPI through this method, and for some reason this board will now POST at just about any speed I choose. I'm currently at 1.73Ghz, 1.86 is becoming more of a reality (need a much better PSU, dammit).

    I'm writing this for anyone else who comes across this problem. ACPI needs to be disabled. I have no idea why though....

    And as for you guys, as long as you believe it's possible, where computers are concerned it normally is. There's always something new to try. Maybe you should think about that next time you say something like "that's not a stable overclock", eh?

    Good job on the overclock :)
