Power Limit & Overclocking 1080 Ti
- Thread starter geordiejc
- Start date
From my own testing I know Elite will hit the GPU pretty hard, if you look at Gregsters post in the other thread, the games that have the biggest increase when using a 1080ti tend to be GPU bound rather than CPU bound. So you can take your pick of games, the Division is also a good one.
In Elite if you set the screen resolution to 1080p (or higher) and set the supersampling rate to 2.0 with all details to ultra, it will downclock the GPU all the time. You can see this manifest itself if you set afterburners on-screen display to alert when the power limit or voltage limits are hit. You won't see all of the downclocking happening as the sample rate of afterburner is much slower than the GPU which will switch speeds in micro-seconds.
Hence this is why peeps will insist their GPU is stable at 2000mhz+ when it won't really be. To be fair, because its afterburner telling them this then they assume it is 100% accurate all the time and AB was never meant to be, it is just a guide.
This is why i wana do the shunt mod. The shunts and bios are restricting power too much. Adding some liquid metal to the too of the shunt carefully can lower resitance and remove the power limit issue.
Im guna get my card under water firsy and do some proper testing and record results then if it annoys me too much ill do shunt mod and ppst results. Its just a pain in the ass to do.
Aib cards have hardware level bypasses which allow the cards to draw more power. Its why zotac state 320 watts vs nvidias 250 watts.

So watercooled my 1080ti and did a firestrike extreme run with no overclock. It stays at 1873Mhz whilst bouncing between 100% and 115% and 118% was the max power usage i saw. I then overclocked it to 2050 and did another run. I saw the power usage jumping all over. Hits the 120% quite often for brief moments it seems and max i saw was apparently 128 which probably was just a spike. It does not hold this frequency either. If i watch closely it bounces around. I even saw it drop down to top end 199x for a second. So it's obvious the reference cards are power throttled. Thing is i did not notice any notice changes in frame times or FPS drops which was what i was worried about when it throttles. So thats good. And if it does drop probably is 1-2 FPS which isn't noticeable as in games FPS variates more than 1-2 FPS so probably not noticeable.
All in all kinda puts me in a tough spot. I could just ignore the fact it throttles and enjoy games or do the shunt mod and push to 2100Mhz which it should hold stable with no throttling other than temp throttle when it passes 32 degrees. Max temp ive seen so far is 40 degrees so it;s dropping 13Mhz. But will the shunt mod net me much more performance? probably 3-5 frames per second tops i guess. So probably not worth the time and effort.
Need to do little bit more testing though with some games. Seems witcher 3 is a good one to try.

Just curious if you did the shunt mod or not?
After a long consideration i decided against it. Reason being is a few people found the shunts coming loose later down the line just because of the nature of liquid metal and well... solder. Only scenarios where this mod would even benefit me would be games that max out my graphics card 95-100% because the shunt mod would provide 1-2 FPS or even 3 FPS at best and providing that extra juice. The main difference would be smoothness because when your clock fluctuates because of power limit you may notice some frame time fluctuations which if your really sensitive to this then you would notice this but for me i never find games that are stressing my graphics card enough to even benefit from a shunt mod.
I tend to lock my FPS to my lower average FPS to get a smoother gaming experience anyway because i hate FPS fluctuations in games as i notice that more than anything going from scene to scene jumping from say 100 FPS down to 70 for example. So i would lock my FPS to something like 72 if that was where it would be my lower average FPS. A shunt mod would allow me to get a higher power limit and allow me to overclock with a voltage bump so i could maintain 2100Mhz which could net me that 1-3 FPS extra meaning my lower average could jump up to 74FPS and i could lock it to that but then is it really worth risking the longevity of my card for this? Probably not so i decided against it in the end.
It's really a extreme mod for squeezing out that little bit extra.
personally if this was something i would be considering, id do like kingpin and solder some resistors on there and invest in a decent soldering iron.

For normal use it is just not worth bothering with and also is not good for the resale value of the card.
I have never bothered with the mod.
i thought my post pointed that out? lol.
Apart from the resale value but that's a given. No one would seek a shut mod card because you would be questioning why they are selling it. It affects the longevity of the card like i pointed out in my post.
I did not know you had already posted about the resale value.
I also did not know that you had posted that I have not used the shunt mod.
Flashing the XOC BIOS can stop power throttling if that is the aim. My FE sits at 2000MHz under load with no fluctuations in speed but at expense of losing access to one of the display ports. Mine isnt a good clocker anyway though - couldnt get 2100MHz stable.
My EVGA 1080 To FTW 3 boosts to almost 2ghz without any clocking.
Yeah the Aorus Xtreme also.
i said in similar words it's not worth it. Also affecting the longevity of a card affects resale value it goes hand in hand. I just seems like you was repeating what i already stated.
Unless you know what I do when it comes to doing a shunt mod there is no way that you could know my views on the subject.
Probably the same way as everyone? Which we was discussing and you replied in context otherwise you would have stated you do it in a different manner? Look what ever man, you're beating around the bush. You literally repeated what i said using different words. End of story. I wasn't looking for an argument i was merely pointing out "i thought my post pointed that out".
