GPU schematics

[AusWolf]

Back when I had a P55-UD6 I wanted to add a switch to BD-PROCHOT so the board would boot with lowest CPU ratio when set and basically got that answer when asking Gigabyte support where the signal came out. Understandable answer but annoying. Had to teardown the cooling, remove the CPU and connect to the socket pin with one end of a meter while using the other one on likely components. Found it and switch worked beautifully. They could have saved me the trouble to look for but I guess it wasn't worth their time. That was just asking about a specific point, not for a full blown schematic.

Schematics is not just about repairs.

On my GTX1050Ti I was also able to calculate and add just one surface mount resistor to achieve a 20% boost in GPU voltage, so at 1.000V set it would actually be 1.200V, just a little over 1.3V on max. Well it actually measured on a meter at +18%, good enough.

On my x99 I was able to see there were 2 free inputs to the super IO so was able to add my own temperature sensor used to measure Tcase and have the reading read in software and be in sync with all other readings.

'Boardview' can be really helpful too.

Yeah, if you can do that, it's great, but I'm sure you see why it's not standard procedure, why it potentially voids your warranty, and why companies wouldn't want to assist with such procedures. The next question after providing the schematics would usually be "I bricked my part, can you help?"

I don't think there's anything "potentially" about it, you mod it you own it. I would like to think people who can read schematics would be experienced enough to not "brick" the board and have to ask questions. For those not able to read schematics they would be pretty useless to them.

Sending a board for warranty is most likely going to be checked, not just to see if it's been messed with but so the manufacturer can see if there's an overlooked inherent problem in the design. It's not like BIOS modding the board way out of spec then covering up afterward. It would be interesting to know how returns compare with the newer nvidia cards vs the older modifiable ones.

Agreed, but someone who asks "what does this mean" upon seeing a GPU block diagram is not the right kind of person to mess with the board, imo.
