Missing SMD Capacitor Rx 560

[ErikHC]

Hello

 

Yesterday i've hit my GPU PCB with the screwdriver, and it ended up ripping a SMD Capacitor off the PCB.

 

I wonder what is the (voltage? consumption? power?) of this capacitor. Idk right what measurement is used for capacitors.

 

All i know is the size of this capacitor, it must be 0402, because it is exactly 1mm long 0.5mm wide.

 

My motherboard is an AMD XFX RX 560 4gb dual fan, and i cant find the electrical scheme of this board anywhere on the internet.

 

The capacitor is underneat an GDDR5 memory chip, so i used the other memory chips that were unbroken to help me identify what capacitor i've ripped off.

 

 

Please help me identify the capacitor capacitance. Again: XFX RX 560 4gb Dual Fan

 

Capacitor underneat GDDR5 chip

have you tried turning it on? there is a very good chance that you might get away with it using it like that.

Yes, but when i hit the power button, the motherboard beeps 1 long beep then 5 short beeps and keeps running with no video. My processor doesnt have integrated graphics.

It's a high probability it will be same capacitance as the one right below it... so you could desolder that and measure it.

 

Voltage rating would be 10v or higher if it's under a chip or something that runs at low voltage (ex ram chips running at 1.x volts) , 25v or higher if they're somewhere on the board that uses 12v (ex around the vrm area)

 

As there's wiggly traces around the ceramic caps, it makes me think the area's right under a ram chip in which case the capacitors are for decoupling or for better power on individual ram chip ... I would say 100 nF would be a likely value but it will be much safer to measure the capacitors around (have to be desoldered before measuring)

Thank you, unfortunally i don't have an multimeter, and i would like to find out the capacitance by myself because i'm afraid of the technician use the wrong capacitor and make the problem worse or even killing the GPU. Once i know the capacitance i can buy the right capacitor and just ask for the technician to solder it on the PCB.

 

By an miracle someone in this forum might have the same GPU as me and an multimeter so this person can tell me what is the capacitance of this capacitor.
