Nvidia Quadro P5000 repair


Recommended Posts

Hi everyone,

 

In the process of doing some inventory management of my (tiny) collection of hardware laptop spare parts, i came across an Nvidia Quadro P5000 lying in a box.

I totally forgot i bought one, and i also found some benchmarks i made last year so i know it worked at some point.

 

The issue i have is that the card isn't detected in the bios nor in windows but the pc is working fine otherwise. I tested it in both 17 ranger and M17x R4.

This indicates me that the card is not shorted, otherwise the pc would not boot (am i right on this)?

 

Any ideas on where to start?

Hi!
I don't know Alienwares, but check out BIOS settings - what graphics mode you use ? Maybe try updating it ?
Do you have two MXM slots ? Maybe try other one (if present).
Card is not shorted, otherwise your power supply would protect itself and turn off not letting you power up laptop.

Hi,

 

To answer your questions :

- i'm in SG mode and i can plug a Quadro P4000 and it is recognized immediately.

- on the 17R1 i only have 1 slot, but as i said, i tested the card on both laptop (and both laptop recognize the quadro p4000 and the rtx 3000 in the bios and windows)

 

The card was known working, if its not shorted, what can it be ?

Looking at the ebay pricing (>500€)

I really want to save it^^

It is moments like this why I need to buy one of those adapter cards (mxm to desktop pci-e) for testing instead of depending on spare laptops due to the extra wear on connectors etc. As for the card if it is not shorted then it could be anything perhaps something went open.

Do you have multimeter  ? Do continuity test on all coils on mxm board and we will see. One probe on ground, second touching one coil at time (don't forget to disconnnect battery and charger!)
Then check voltages on all coils

Also maybe some HQ photos from both sides ?

Here are some photos of the card.

When you talk about probing, wich component are you talking about (can you circle them on the picture)?

The probing you are asking is done by putting the multimeter in continuity mode?

Can you show better photo of those places ? It may be just some dirt, but we have to be sure. Also try cleaning with isopropyl alcohol silicon die and see if it is chipped off somewhere.

Check in continuity test those coils, I numbered them. One probe to ground (ex. those holes for X Clamp) and second probe to coils.
Write number showing on multimeter. You can also double check by using ohm mode.

Good luck!

I took a closer photo of the capacitor. It does seems to have suffered some damage, no ?

Check it with probes on both end on ohm testing mode

In continuity mode i have those results :

- Coil #1 = value fluctuates a lot, cannot stabilize measurement

- Coil #2 = value fluctuates a lot, cannot stabilize measurement

- Coil #3 = value fluctuates a lot, cannot stabilize measurement

- Coil #4 = 30 > value > 130

- Coil #5 = 118

- Coil #6 = 65

 

As for the suspected damaged coil on the back :

1392 in continuity mode, no readings in ohm mode

 

Any ideas on what's going on with this card?

I wonder about 1-3 coils, theyre core supply voltage. Rest coils and caps are okay.

gpu heatsink cold ?

The card isn't heating at all, i mounted to test without heatsink and the die was ice cold...

Try to reflash vbios chip using external programmer.

And before soldering out flash chip check if it have 1,5v supply on its first or last pin. If no 1,5v then vrm is faulty

I do not own an external programmer...

What voltage are you talking about, the vBios chips' or the mxm connector ?
