Max cpuid value limit

[bazzhard]

I have a Asus p5e3 Deluxe motherboard, which currently doesn't have a OS installed.

I turned on the PC and it told me to go into setup, which I did. As soon as it had completed this it told me something about editing some of the settings in the BIOS for the CPU. So I did.

Managed to enable the Max Cpuid value limit and now when I turn the PC on the monitor doesn't light up.

Is there any way to resolve this?

Reset the BIOS by pulling the CMOS battery, or there might be a jumper/button somewhere to do that. When you go back into the BIOS, leave that setting alone.

It would help if you post your system specifications. Do it in the user CP on this forum.

When I first changed this setting, it displayed an Intel image but some of the image was missing and it would stop there.

Then I tried removing the battery and removing the jumper. After that the screen would no longer power up.

Sorry if I wasn't clear, but you will need to put the battery back in and put the jumper back in its original possession or the board will not boot, by doing one or both, it resets all the BIOS settings to defaults. In all my years of OCing and building my own systems, I have never changed that setting.

@Black Panther System Specs are now up

@Dark2099 Yes both are back on the motherboard. I do feel a bit of an idiot for changing the setting. Just don't really see what I can do to fix this. I just hope it's a problem with the motherboard and not the processor.

I wonder if that PSU has enough power for your system and that isn't a problem, what graphics card are you running?

 

[bazzhard]

I think it's suggested you run a 400w PSU.

Graphics card is a Radeon HD 4550 that includes 512mb of ddr2 ram.

Did you unplug the power supply when you pulled the battery?

 

[bazzhard]

I didn't unplug it but there is a switch on the back of the PSU which I turned off...

 

[jellyrole]

Try doing that same stuff, but unplug the cable from the psu as well.

 

[bazzhard]

Okay I've now tried that, still not working =/

 

[Corduroy_Jr]

look for c-mos jumper on motherboard set it to 2/3 pin, remove battery, unplug 24 pin, plus 4 pin cpu connector wait 5 mins, plug everything back in, if no go, try another psu or mem in one slot at a time, its trial and error at this point

How come you are so sure it was the "Max Cpuid value limit" that caused that?
Also, you said that you changed some settings in the BIOS, which ones?

I always leave the CPUID limit option in it's default value because first, I know what it does and nowadays it doesn't apply to roughly all of the cases and second, the motherboard manual clearly specifies you leave it in it's default value...which is disabled.

Clearing the BIOS is a simple process. Just follow this steps:

- Shut down the PC;
- Unplug the PC;
- Wait 5 minutes (usually enough time for all of the capacitors to discharge);
- Press the Power on button. This will discharge any remaining electricity in the PC without turning it on;
- Take the battery out;
- Wait 5 minutes;
- Put the battery back in;
- Plug the PC;
- Turn it on;
- Enter the BIOS;
- Go right to the option "Load Defaults"/"Load optimal setting"/"Load default settings" and select it;
- Exit BIOS (it will reboot);
- Done!

That should do the trick.
As for the PSU, I guess if the system doesn't hit full load the PSU might take it...but I have my doubts.

The PSU is under powered (or defective), or the bios is corrupt. Like the others suggested, test with another PSU if possible.

"Max Cpuid value limit" has nothing to do with stopping your graphics working.

Try putting your graphics card in a different slot or a using a different card.

Graphics card is a Radeon HD 4550 that includes 512mb of ddr2 ram.

A 300 watt supply is recommended for those cards, so the 350 you have should be adequate, unless it has taken a dump and gone bad. If you have or can get access to another supply try it; if you know how to test one; get a multi-meter\psu tester out and test it.

It is, also, possible the video card, memory, motherboard, monitor cable, or human error is the problem.

Un-plug\dis-connect any devices not needed to boot (DVD\CD, hard disk, audio cards, usb devices (sticks, hubs, dvd\cd, floppy drives, harddrives, bluetooth, etc.) and try, if it works with devices disconnected, plug one in at a time until it doesn't work.

Check all your power connectors, re-seat the video card, ram, etc.

I don't know which monitor or connection you are using, but check and make sure it is set for the type of output from the card, if it has the option (vga, dvi, etc.).

Test your ram or try booting with one stick at a time, like Corduroy_Jr mentioned.

The MAX CPUID value limit has no efffect on the boot up process, all it does is report (false) CPU info ( 03h) to the OS for compatibility of Pentium 4 (HTT) in old OSes, such as, Windows 95\98\ME. As you had no OS installed it had nothing to do.

When, and if, you re-set the bios it would have defaulted back to the correct setting.

You need to be a Sherlock Holmes and do some detective work. Goodluck.

I will be buying a new PSU and testing it in the following week.

As for the bios being corrupt, there is no way of fixing this, right?

The only setting I changed in the bios was enabling the max CPUID.

Thanks for all your responses!

Yes, go for the PSU and see if the problem relies there.

But, I still got to ask, from all of the options in the BIOS, especially the ones you should change after the 1st boot, did you go straight to that one and change it??
Are you installing Windows 95/98/NT/Me?

I still doubt the BIOS went corrupt, but even if it did, you can order new BIOS chips from some stores. They sell new chips with BIOS already in them for this cases. There are other ways, of course, but they require electronics knowledge and can get quite on the complex side.

 

[bazzhard]

The only other option I changed was boot from the disc drive before the floppy. But straight after I changed the Max cpuid and that's all I did.
I am not installing any of them windows, hadn't got near to the stage of installing windows either.

 

[_JP_]

Alright then.
My last question would be, did you read the motherboard's manual?
Because I'm pretty sure it said not to change that last option.

Anyway, if the problem ends up not being the PSU and it really is the BIOS that went corrupt (not going into POST/beeping), look for something like this: New BIOS chip.

The symptoms indicate a corrupt a bios "it displayed an Intel image but some of the image was missing", sure hate you have to buy a PSU and don't have another on-hand for testing. I'm not sure of your location but Biosman ships internationally for $5.00 US (shipping only) to most countries if you can't find a chip close to home. There are instructions at the site for removing the chip as well.

Unless he has a surface mount setup for extracting and soldering the devices, he does not want to replace the bios chip. It is soldered on the board.

Wow, I really wasn't counting with a soldered chip. Even my cheap-ass motherboard comes with PLCC socket for the BIOS chip.
I think this is just a design flaw from Asus.

It is no design flaw, most vendors solder the packages to the board to eliminate this problem:

(hardware) chip creep - Gradual loosening of an integrated circuit ("chip") in its socket as a result of expansion and contraction during the normal heating and cooling cycles of an electronic system, combined with vibration, e.g. due to cooling fans. The chip can loosen to the point that poor electrical contact between chip and socket reduces the signal quality, causing failure. Pushing chips back into their sockets can cure such symptoms temporarily. Permanent solutions include soldering chips directly to the PCB and clipping the component into the socket (as on some in-line memory modules.

The same phenomenon can affect anything plugged into a socket but not held securely in place, e.g. a circuit board plugged into an edge connector on a motherboard or backplane can suffer "card creep".
