OK. it's just few posts back. So what i did interpret wrong you did some mod on that 5770 card that you RMAed after that.
And unless i understood wrong, u were trying to calculate the needed resistance for giving the gpu 1,35volt via trimmer right?So if for the default resistance,your reference voltage was wrong then wrong would be the other calculations too right?Iwas trying to be SMART.I was trying 2 b of help here
ofc you did when you tried so hard to understood it wrong way. Picture is self explanatory, and i went explaining why that Lazzar mode that youdid is wrong and where you should mode and what. And thats not trimmer to get you1.350V except you just do that w/o unsolder original chip on pin that i mention. If you understood modding it's not had way to understand what you doing wrong now. I say you have to unsolder original load thatgives you that1.35V. Read my first reply to Lazzer and that second to you. and it will clear up for you.
Don't look just at picture something is in the text. So 1. unsolder resistor on pin 9, 2. solder that 2k2 resistor (my hardmodder) on its place, 3. solder 10k trimmer/pot via some wires and thenyou should get 1.240V-1.460V regulation. I know i should sketch it down few times before. I suppose you werent trying to play smart but cmon you could read that two posts when you have time and pretty simply figure it out.
Anyway why you even bother with hardmod you didnt answer in my reply to you when it will only void you warranty and softmod works more than fine?
I'll just said that memory is much more voltage sensitive and since it's graphic card memory it has vdd/vddq regulation also.
I don't see it on his photos. How many of them are on the board?
