You can read voltages from big inductors or from capacitors. There are plenty of guides showing this on the web

Thanks for the reply TiN. Appreciated.

If you don't mind, one more question... Your Uncorking GTX 980 guide, the resistors that need to be removed to enable adjustment on feedback sense. When I'm done with the card do these need to be soldered back on for the card to function? Also, just making absolutely sure that the VR's used are 50 ohm and not 50k. I initially picked up 50k's.

Again, thanks man. I figured the SMD caps on the back of the GPU would give me a proper vGPU I just wasn't sure. :-)

50-100 Ohm for GPU and 50k for memory/PEX.
Why would you want vmod your card. It gives nothing on 90%(if not all) Maxwell cards on air..

It is on water, however I am starting to think the same thing at this point.

So... I did remove the feedback sense resistors however. Do I need to put those back on for the card to function normally? Apologies for the n00b questions.

Very much appreciate the responses TiN. Bigtime.

From what I understand those resistors when removed take about 100 ohms away from the circuit and youre gradually adding it back with the 50ohm VR? Meaning the card will definitely need those resistors back on or the card will boot up past 1.85v, the max of your tutorial.

Or am I way off?

I've decided to forgo the mod for now, just need to be sure about those resistors.

Thx.

You don't need anywhere near 1.85V even on LN2 for 2300MHz

Thanks again TiN for the responses. Super helpful.

I'm in slightly uncharted waters here I guess with Maxwell voltmodded on water. My loop is quite decently designed so it can whisk away heat nicely. Nothing like LN2 of course.

Thinking around 1.4v max for 24/7? Currently loads @ 42c /w 1.275v.

I'd be happy to be proven wrong, but so far raising voltage on air/water is just waste of time on Maxwell. This was covered many times here on forums, and elsewhere as well.

it's 50 ohm for mem and pex also right? The resistance is so close with all 3 mod points so I would imagine so. I just had to ask after I read post above. Going to epower an old 980 this weekend.

Cant wait for new epower to release, they look amazing.

50 ohm works great for mem and pll, thanks for guide, next step epower connection.
