NVIDIA GTX 1080 Ti Owner's Club - Page 726

post #7251 of 10690
There're actually 2 TDP limit,
Total GPU Power (normalized) [% of TDP] and Total GPU Power [% of TDP]. GPU-Z reads out Total GPU Power [% of TDP] whereas AB reads out Total GPU Power (normalized) [% of TDP] . HWiNFO64 reads both TDPs. Both TDPs limit the max power the card can draw. I can't find a way to increase the normalized TDP unless I flash a BIOS with a higher normalized TDP.

The shunt mod only affects Total GPU Power [% of TDP] but not the normalized TDP.



You can see my card (shunt modded) hits power limit because of the normalized TDP.

Pascal doesn't not scale well with voltage under room temperature. Voltages higher than 1.093v can have weird problems. I ran my gtx1080 on Strix OC bios. When I increased voltage above 1.093v, event viwer started to be flooded with PCIE WHEA errors regardless of the GPU frequency.

So 22-30Ohm would be lower power limit?

By the way did you solder that on? looks like a nice job thumb.gif

I'd recommand 22Ohm, it's 2.82x the original TDP, more than enough for anything. The shunt resistor will lower the RC constant of the sensor filter circuit. it means the power readings become more noisy with more spikes.

No I didn't solder them on. I simply secured them on with some non-conductive thermal glue first, then applied some silver paint. It works very well for me thumb.gif

Everyone has already reported poorly results with it, and not just it but all bios. Just use stock. Through all my testing, flashing and trying out bios was just a waste of time.

If you really desperately need that power, just shunt mod and be done with it.

What are you running here to have that power limit?

you need use it with shunt mod. The bios along doesn't not help much. My card manages to draw 450w of power with shunt mod + palit bios

Did SuPO 4k, what about clock drops from temps went from 2025-1987 gradually. No jumping all over the place.

EDIT: Just did 2037 at 1.031v and it only went down to 2025.

thumb.gif good old furmark. It's drawing 450w+ power when I took the screenshot. Shunt mod + palit bios

What's the point though? It runs like crap, if you run benchmarks that aren't power hungry where stock wouldn't power limit, Palit gets worse scores. Heck users without shunt score better being power limited than having 30 extra watts.

So what's the point? Draw extra power to get worse results and higher thermals plus higher risk of damaging card? In other words, all it accomplished for everyone is to get worse results but in situations where that 30 watts helps, it only helped barely match the stock BIOS. It sounds counterproductive to flash a bios to get more power and heat so that it can do worse or tie with the stock BIOS.

Lastly, I really don't think you did your shunt right, something is wrong because I don't hit power limits like you do in that image. I can draw 410 watts on my card. But why do I need more power than this? Superposition doesn't power limit me. Games will never run like superposition, so why do I need 500 watts into my card?

I'm just using a +80 overclock in EVGA Precision X with power and thermal sliders set to max. I never break 43C in game ... don't use a curve ... haven't overvolted either.

Also, I get power limiting all the time ... like every 5 to 20 seconds ... but things are smooth as silk and frames are always 115FPS to 144fps depending on the area so I mean, is that power limit thing even anything to worry about? Don't the cards just do that by default?
