Seller Note “Black screen with backlight”
Summary
- Resistances seem fine
- PEX 384Ω
- vcore 3.9Ω
- vmem 18Ω
- Seller’s note is not entirely accurate, the card exhibits light artefacts, reaches windows and crashes on driver load. There is also similar coil whine to Gigabyte Windforce Extreme GTX 980ti Card A
- Mats has trouble running put the below results were obtained, uncertain if they are a reliable indication that chip FBIOF0 is the issue (pattern looks strange, might be the memory controller?)
- Will dismantle to identify the vram type
mats version 400.184. Testing GM200 with 20 MB of memory starting with 0 MB.

very niceee! gracias!
Hi! nice job! hey you have the reference measure of gigabyte gtx 980? i need to know if 3.3v can measure 500 ohms. thx
Thanks for the comment 🙂 Unfortunately, I don’t have a 980 and never have yet. The closest I have are these 3 980ti s and they are a little unusual (high end). I have a 970 that is more like a reference card.
The 3.3v rail on this card is 875 Ohms just for reference.
