What happens when I lower the power limit in MSI Afterburner to 90% on my 1080ti?

jchon930 · Jan 17, 2018

I decided that I don't want to squeeze every last drop (temp pegged at its 82 degree limit at stock) out of my 1080ti and I lowered the power limit and dropped the core clock to -50.

I did this solely for longevity and reliability, plus I didn't need the extra 2-5 fps. Is the power limit automaticallly throttling the core clock/memory speed to compensate for the lower watt draw when I decrease the power limit to 90?

Am I correct in thinking that this MAY increase the life of the card and reliability if i do keep it running slightly under-powered at max performance?

Yes it will run the card slower, and should be cooler as well. But honestly the cards are designed to run that hot and throttle themselves accordingly.

I don't think so.
Not overclocking it, i.e. running it on stock settings, should be long term guarantee enough. As 100cotton said:

yeah, it works fine at 100%. I'm just a little paranoid from when I used to own a gtx 570 and ran very unreliably. I'm sure the mfg process improved since then but just wanna keep a cushion from the max temp.

Cards these days will auto O

C as far as they can until they reach a limit whether it be Temp, Volts or Power. Most likely even at 90% its beyond the stock clocks and in the boost range. You're just reducing how far it can boost. Keeping the temps down with a custom fan profile will help as well.

Yeah shouldn't matter, thats what the throttling is there for. Sounds like you just got unlucky with the old card, can understand the worry about your new thousand dollar card, but most likely if something goes wrong its probably out of your control.
If you are really concerned with temps just put it under water and be done with it

won't see temps over 50.
