Re: GeForce GTX 1060 short on PCIe 12V
Meanwhile this 1060 is running again, however there is still a weird issue with the card that I haven't been able to figure out - The card dynamically switches between power states and boosts the RAM-clock however the GPU clock stays fixed at 139MHz regardless of the current power level. Some diagnostics I did:
- I measured the 3 GPU power phases with my oscilloscope. All are present and operational. Under load all three phases operate somewhere between 320 and 430 kHZ. When the card is idle the bottom phase stays at ~320kHZ...

Re: GeForce GTX 1060 short on PCIe 12V
Thanks for the reply harp. According to the RT9403 datasheet could be 100 nF. Eyeballing the cap sizes is definitely plan B. If anyone knows the exact sizes or has schematics it would be great if they could post them here. If not I'll do it exactly the way you suggested.Leave a comment:

Re: GeForce GTX 1060 short on PCIe 12V
Thanks for the tipp with the NTC, harp. Unfortunately the current draw was just to low to get any conclusive hints based on temperature and the card ended up in my drawer for quite some time. Yesterday I found some time to look at it again and finally found the fault. A ceramic capacitor (SC532) caused the short. I removed it and now 12V to ground resistance is back to 4.9kOhms, which seems healthy to me.
I also took of another ceramic capacitor next to C113, which has a thin black line on top, could be a surface...Leave a comment:

Re: What if any, is an acceptable resistance here?
Undamaged coils will show as a short on a regular multimeter, not open circuit. The resistances you measured there are very likely not the resistances of the coils but resistances of components located between the coils and ground....Leave a comment:

Gtx 1060 6g (p/n: Ne51060015j9-1061d)
Hi, I'm looking for schematics for a GTX1060 6G (P/N: NE51060015J9-1061D). The card is not branded but searching for the part number shows identical looking cards from both Palit and Gigabyte. The layout and part numbering for the card seems to differ substantially from that used on other 1060 boards. -

I think I might have identified the part, I'm not 100% sure but I think it might be an [URL="https://www.richtek.com/assets/product_file/RT9403D=RT9403E=RT9403F=RT9403G/DS9403DEFG-00.pdf"]RT9403EGV8[/URL]Re: GeForce GTX 1060 short on PCIe 12V

Re: GeForce GTX 1060 short on PCIe 12V
I think I might have finally found two suspicious parts, SC532 and SU5 (see picture below). Using Diode mode I measure a drop of 0.000V between pins 2 and 4 of SU5 and both sides of SC532. Can anyone identify part SU5 on the picture below? SU5 is labeled "08=R3M"....Leave a comment:

Re: GeForce GTX 1060 short on PCIe 12V
Today I finally found some time to take a look at the board again.
Thanks for the hints MasterCap. I assume the card might use PCIe 12V for the memory. Without schematics there is no way to be sure though. I think Q16, 17, 18 may belong to the memory power supply whereas U10 ... U14 belong to the GPU supply (U11, 13 were unpopulated though, probably the same board is used for 1070s as well, which require the additional phases).
I checked the HDMI output there seems to be a short...Leave a comment:

Re: GeForce GTX 1060 short on PCIe 12V
Hello ahmad9794,
thanks for the response. That was my first thought as well. As you can see on the first two pictures I have already removed all MOSFETs responsible for supplying GPU and memory from the board, unfortunately the short is still present.
Since the board only draws ~40mA I suspect that some smaller component maybe a capacitor, inductor or sth. like that went short. However so far I'm unable to locate the source of the problem.Leave a comment:

GeForce GTX 1060 short on PCIe 12V
Hi everyone,
I've been trying to find the cause for a short on 12v (~20 Ohms to
ground) on a GTX 1060 for a while now, The card has no branding but
as far as I can tell it is a Palit model. The short only shows
up on the PCIe-connector but not the PSU connector.
Initially I suspected a faulty MOSFET in the memory power supply.
However after removing most of the MOSFETS/integrated power stages
from the board: Q16 (SM4377 CS70X), Q17, Q18 (4503NH CS740), U10,
U12, U14 (SIC632) and the PWM controller (NCP81174) the ... -
