overclocking and video card

[neveryona]

I just recently overclocked my 366 to a 460mhz. I was just reading from someone else's post that this forces other cards to run faster too. I have noticed that sometimes when I boot up, the monitor is dead...doesn' want to come on. I have to try again a few times before it will go. Could this have something to do with it?

It has EVERYTHING to do with it http://www.PCGuide.com/ubb/biggrin.gif . Unless you have the ability in your BIOS to slow the devices down...it's usually a setting to have PCI devices run @ 2/3 the FSB speed, then you will run a big risk of cooking your vid card. The better way to achieve overclocked results without the degree of risk you run by bumping up the FSB or upping the voltage is to try to step up the MULTIPLIER ........then if it doesnt work, nothing gets cooked. I assume you are overclocking an older Intel Celeron...right?

If you OverClocked by raising the FSB (front side bus) then most definitely would impact your other cards. If you raise the FSB by 10% you also raise the PCI, ISA, AGP abd whatever other busses your MOBO has by the same 10%. Certain cards operate under very tight tolerences and as little as 5% out of spec could cause them to malfunction. Another consideration when OCing is heat, most people realize that the CPU will generate more heat and take steps to cool it but a modern video card has its own processor, and OCing the bus will OC it, too.

So if you are having problems with your video card, and other stability problems I'd say OCing was to blame, especially since you went by a 25% OC.

Overclocking is not something to do on a whim, it must be carefully investigated as to the benefits and risks. If the machine is used for critical data (work, office) then don't even think about it, but if it is a machine primarily used for playing (on or with) then experiment but be aware that you can cause data loss and/or physical damage to some components.

Do Vulcans even have to debug?

The cpu is a Intel 82443bx Pentium II(r) Processor MMX. How do I go about stepping up the multiplier. Or maybe I should just clock it back a bit. What do you think. And can I just clock it back throught the software or do I have too change jumper setting or what. It wasn't actually me that did this, have been arguing the point that I think he overclocked it as the system like to crash, reboot at odd times etc. SO I think I would like to just clock it back, but not really sure how. All I know is that I don't want to cook my system. Is there some little program out there that actually tells you if your cpu is running too hot? I seem to only be able to find ones that can coll them off.

You have to Open the case and make changes to jumpers on the Motherboard in all likeyhood. If you have never done this before, I would get the person who "did it for you"/or to you http://www.PCGuide.com/ubb/biggrin.gif to put it back to specs. Since he wasnt aware of how to bump up the multiplier, rather than the FSB, I DANG SURE wouldnt trust him to try to speed it up any other way....I would go back to specs and start saving for a faster processor myself.

I wish I had kept my mouth shut about multipliers in the FIRST place http://www.PCGuide.com/ubb/biggrin.gif

I don't know...I kinda liked likeyhood...personally.Well, I could give it a try...asking him to do it...but do you know what it is like to be a computer geek wannabee dealing with a self claimed master?I have fooled around with jumper settings before, after alot of research and hair pulling and was successful. I am taking a repair course right now...so I will keep on with the research through here and some other sites that I have found useful...until I become one of the "informed" and until then hope that the cpu cooler I installed will keep everything from blowing up in a ggrreat big cloud of smoke!

Good idea about the cooler, it'll help keep everything in one piece. If you can find the MOBO manufacturer then you can go to their website and hopefully find the manual for it, or you can check out MotherBoard Homeworld (http://www.motherboards.org) and use their online tools to try and track it down.

OK......here are the settings for that processor to run at specs. The jumpers MIGHT be stamped on the motherboard so you wouldnt need a manual necessarily:
Front Side Bus or Bus Speed: 66 mhz
Multiplier: 5
Core Voltage: 2.0
All three of those are probably stamped (albiet in VERY small lettering) on the motherboard somewhere with the jumper #'s that have to be changed. Good luck if you try it http://www.PCGuide.com/ubb/biggrin.gif

Thanks, I will print that out and give it a try. Just out of curiousity, how would you go about overclocking. Manually on the motherboard or through the computer software?
