ÊtaPegasus Posted March 20 Share Posted March 20 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?

Mashcar Posted March 21 Share Posted March 21 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.

ÊtaPegasus Posted March 21 Author Share Posted March 21 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^^ Laptops : Alienware M17x R4 | i7-3630qm | PNY Quadro RTX 3000 | 16Gb G.Skill Ripjaws DDR3 1866MHz Alienware 17 R1 | i7-4940mx @4.0GHz | Nvidia Quadro P4000 | 32Gb G.Skill Ripjaws DDR3 1866MHz Dell Precision 7550 | i7-10850h | Nvidia Quadro RTX 5000 Max-Q | 64Gb DDR4 3200MHz Desktop : Asus Rog Strix B550-F Gaming Wifi | Ryzen 7 5800x | Sapphire Nitro+ RX 6700XT | 32Gb G.Skill Trident Z DDR4 3200MHz Link to comment Share on other sites More sharing options...
nforce4max Posted March 21 Share Posted March 21 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.

Mashcar Posted March 21 Share Posted March 21 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 ?

ÊtaPegasus Posted March 26 Author Share Posted March 26 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?

Mashcar Posted March 26 Share Posted March 26 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!

ÊtaPegasus Posted March 26 Author Share Posted March 26 I took a closer photo of the capacitor. It does seems to have suffered some damage, no ?

ÊtaPegasus Posted March 29 Author Share Posted March 29 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 ? Link to comment Share on other sites More sharing options...
ÊtaPegasus Posted April 1 Author Share Posted April 1 The card isn't heating at all, i mounted to test without heatsink and the die was ice cold...

Mashcar Posted April 3 Share Posted April 3 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 Link to comment Share on other sites More sharing options...
ÊtaPegasus Posted April 9 Author Share Posted April 9 I do not own an external programmer... What voltage are you talking about, the vBios chips' or the mxm connector ?
