Topic: [SOLVED] 5830 vreg component values? (Read 2190 times)
Gosh I'm stupid. It was a zero resistor! Miracles do happen. My HD5830 runs again!
Miracles do happen. My HD5830 runs again! Whatever value measured will be fine. I can calculate the real value of those components if I only get the reading with components on place.
So if it's not too much of a trouble, I'd be very happy if you measured the values for me
avoid3d told the correct method. The upped component may not be a resistor though..

Not to be a dick but...
No, no you can't.
A) You don't even know what type of device you're measuring. Is it a diode? Is it a resistor? Is it a transistor?
B) You need to remove the device from the board to properly test it.
C) You can't calculate shit if you don't know what the rest of the circuit looks like. or have equivalent values for the surrounding circuit.
D) You need a fairly decent quality multi-meter to accurately read anything other than a resistor.
Your best bet is to see if there are silk screen markings indicating what they are, or see if you can read any numbers off of the other devices next to the ones you're missing with a magnifying glass.
Your points are valid, yes. I don't know what component the white one is. Indeed, removing the components would be the best and only way to get accurate readings.. But maybe it is too much to ask for someone to break their graphics cards just to help me repair mine? The black one is a resistor and any value measured would be helpful for figuring out the real resistance of it. I can find out enough of the circuit to "calculate shit". Thank you for your advice but there doesn't appear to be any markings on the components.
Whatever way, I'd still be glad if someone attempted to take the readings. Perfection is not what I demand for my 5830 is a 100$ paperweight at the moment. Any value measured would give hint to the right direction. Thank you.

Bump.
I'm still hoping to fix it

Haha people are douchenozzles you still need the reading, I have a friend with this card and I can organise tomorrow. consider it an attempt to become more involved in this community.

so smarty pants have you looked at the cuircut then 
I havn't but maybe it is between two components of negligible conductivity

He would like you to seat it to resistance mode ( Ω ) and measure the resistance of the two components in the green block.
Make sure the card is not connected to anything, then put one probe on the one side of the resistor, and the other probe on the other side, and record, and repeat

You won't be measuring the resistance of the component, but of the whole circuit between these two points. Good luck.

say I have this card and a multimeter what do you want me to do ?
resistance/other values when the card is off.
i managed to break and lose the two components
EDIT: Whoops, I just noticed this thread is not in the hardware subcategory. Could it be moved please?

need to know the resistance while the card is off or the voltage while it's on ?
Hello!
I recently bought a Sapphire HD5830. It overclocked fairly well with stock voltage, but being an idiot, I decided to overvolt it. :/
So I managed to break a few components.. I'm determined to fix it, but I don't know the values of some components. Could someone please do me a favor and measure these two components in the green rectangle?
