multimeters?

[mattsmall]

i got a multimeter and it go's from 500 to 0 OHMS and i want to know the voltage going to my videocards vmem and qpu so what would the converion thing be?

on the core of my geforce2 it says i have 1.5 ohms?

does it measure voltages? ;D

Ohms is resistance

There's no conversion. You just have to set the multimeter to measure voltage and then measure it. I hope you know damn well what you are doing because it is really easy to short out a couple smd pins with a multimeter probe.

i havnt used it so dont worry about me shorting anything.

i im using a 1k resistor like the site sayed its just i wanted to see what the voltage is on my videocard was.

Well all I'm saying is when you do go to measure the voltage on your video card, but very careful. Maybe I'm not understanding what you are trying to do, though.

link us to the site, and we'll help

i dont need any help now i have to go get a multimeter that displays voltage.

i got one of the cheap dollar store multimeter.

the site said that the stock vcore was 1.46 and i wanted to see what the voltage on my card was stock.

...cheap dime store multimeter's read voltage "just fine"....within the limits of accuracy specific to your meter. At a glance I'd say there's no reason to buy another.

Maybe you should give us a link and consider some help from folks that have done it, oh, a time or two.....??

Just trying to help - B.B.S.

Measuring most things in a computer(execpt PSU) with a cheap multimeter is a BAD idea unless you know what you are doing. Cheap multimeters usually have rather LARGE bulky probes, this makes it very hard to place the probe just on the contact point you want. Plus because the the tips are not sharp they will tend to slide off the contact point.

Decent multimeters have replacable probes for different uses, and for a circiut board you want ones with very thin sharp points. Also I have NEVER seen a multimeter that does not measure voltage. I have seen ones that do not measure current, but ones that only measue resistance are called ohmmeters.

Also post a link to the site you are getting directions from, it usually helps clue use in.

edit: you can do things to make a cheap probe easier to use, I like to take thin wire wrap around the tip and use the thin wire as the probe.

There is a guide on www.extremeoverclocking.com that shows how to properly measure the draw from the ATX connector on the motherboard. The ATX connector is the most accurate place to test.

By definition, multimeters measure voltage. Although if it is an el cheapo then I'm willing to be it's an analog, in which case it would be a bit difficult to get the precision you are aiming for.
