Unlike Maxwell pascal's DDR5x uses ECC and even if it don't crash or artifact it will held back performance due to error correcting due to unstable clocks.
.
Start low and work your way up till you see no performance improvements.
Set voltage +100

Adding more voltage is the last thing he should do. More voltage equals more power draw and higher temps. So he will throttle even more.

I run +100 just fine for 2060 i see maybe 10-20Mhz drop when power target hit and only really in benchmark nothing to cry over as it no lost in frames. It also jumps right back up to 2060.
If i run at default voltage my clock drops down to 2010/20 overtime and it never goes back up until i set +100 again.

Heat is another story but not news that pascal runs better when kept cool.
You have to set a custom fan profile with FE the default profile is crap.
My Ti never goes ever 75c with +100. And yes its not quietest but it also isn't earth shattering loud.
Ill be installing EVGA hybrid kit like i did with my 1080 SLI then my card will run even better.

Not adjusting your voltage can cause down clocking as does heat and hitting power target.
You have to find sweet spot for YOUR GPU not all of us are lucky to receive a golden chip that requires no extra voltage at higher clocks

Here is my Ti @ +160 with default, +50 and +100 voltage In GTAV @ 1440/165zhz

The max default 1.06v is not enough to sustain 2060 on my GPU so GPU boost down clocks my core.

edit

And i do agree with you its the last thing you should do.
But i always find it necessary with my luck in lottery.

You will find that adjusting memory speeds even by 5 MHz in either direction will have an impact on your scores. There's a bit of a hill and valley effect over the course of a ~25MHz window.

There is also error correction that starts to kick in as your memory starts to hit its limits. It will cause a dip in scores when it starts to engage. This is a feature of GDDR5X that is not present in traditional GDDR5.

You're not wrong about memory power eating into your power limit, but that's secondary to other factors.

Open up heaven and pause it in a location where there's minimal movement going on in the background (like when it's staring at the cobblestone path). Watch your FPS indicator and adjust your memory speed by 5MHz. You'll see the FPS counter move around by a couple of percent each time. Use this as a tool to dial in your best overclock.


WAS about to post something long about find this out myself using Valley Benchmark and testing memory from +250 to +600 memory OC. I THOUGHT I had ****ty memory as a few data points chosen in 25 MHz point didn't do anything for me. Guess my 1st stab in the dark was a good Peak.

About 2 Min into Valley after the rain effects, there's the flying thru the mountains. Trees and what not. Most stable FPS counter I found to use. Rain scenes used the most VRAM...but also jumped around like crazy.

Got my TI for a week, did some air test, throttle a lot by temps so I install the EVGA hybrid watercool.

Temp never when higher than 45 but I was getting pwr limit a lots.

2000ghz in game stable but in 3dmark graphic test one I hit power limit and drop to 1900 even 1850 sometime.

So today I decided to remove this limit.

It was a scary day.

I decided to do the 3 x 10 ohm resistor on the bord
But I only had big resistor, but a good soldering kit. decided to give a try.

Its a this moment you realize how your hand shake a lot.

But I manage to do it.



I did verified that they where not touching elswhere or eachother and that the connection where good, and each one was isolated with shink tubing after that to be safe.

Then at the last moment of puting back everything together a screw fell of the screwdriver and ended in the fan... stuck to its magnet at the center.

After a long 5 minute of despair (did not want to remove everything again) fighting the magnet inside, I decided to take a bigger magnet and win against the fan loll



Back to business

The computer boot to windows, then 3dmark start but after 5 second of 3d rendering he driver fail, it was ok when downclock to 1400....

The power consumtion did lower, gpuz was 25 TDP but afterburner was showing 80% power the 5 seconde the test could run. (aren't they suppose to be the same?)

Then windows crash in a rainbow of color...

Thought I killed it but it boot back ok.

So I decided to remove the resistor to see if I did not break something while soldering but just removing the resistor, the card came back to normal.
Even seems to hit power limit less than before maybe because I altered the capacitor with the heat a little.

They where 3 10 ohm resistor, check with mutimeter.

My card did not like this mod or I did it wrong.
Will maybe try shunt mod instead but another time to much stress for today ;-) it time to play game with it.

I should try the shunt mod. I got microcenter replacement plan to avoid MSI and getting new GPU is mine needs to be replaced.

Though I'm wondering if it's worth while to get some and redo the tim on my card and my cpu. I have mx-4 on both. smile.gif
i came from that on my cpu. gained a few degrees but i had put too much paste on time before. It is (TG:K) better, no doubt. I mean, mx-4 is a $6 amazon add-on, though, so it's the best value imo. But at the same time, i was attempting to get sub 60c on air so i needed the absolute best paste. i actually achieved it in most games i play. a few it games at 63c. all in all, on air, that's nasty. added bonus is my drives/mobo/etc are all 30-32c because my case is super cool. My house's ac/heat is kinda loud and now my pc still isn't louder so it bothers me none. Probably going to skip the hybrid mod this time and save a hundred on that one.

Since it was ignored, Iam posting this again.

I have a question for you folks, When the non reference 1080 ti cards will arrive, I plan on playing quantum break after I get one, but can someone do a test or a little benchmark with quantum break ? I prefer to play on 1080p and everything ultra with upscaling turned off obviously and with my gtx 980 ti I get around 40 - 45 fps max, in combat scenes even below 40. Can someone do a test for me on how it plays and performs on a 1080 ti please? Thanks. Important thing is to leave the ugly muddy, blurry upscaling option turned OFF

Oh and please test mafia 3 aswell, thanks

Man this is too hardcore for like 2% extra performance.

Why not doing the less risky, the less fail prone shunt method in the first place?
Don't get me wrong i don't want to offend you, but i don't understand "why"

I was bored biggrin.gif and I like to mod all I have for fun.

Its simple, I did not had liquid metal and where I am I could not find some in my computer shop, but I had some resistor lying around and thought it would be the same just done differently. (reading that https://xdevs.com/guide/pascal_oc/ make it look like it was better this way too)

I am going to try the shunt mod with rear defrost windows repair kit, I try a little with the multimeter and it resistance seems low (one cm long was 30ohm) but not 0 so maybe it will help a little more.

And its weird but I really gain something just by installing and removing the mod, I can now hold 2000GHZ in 3dmark instead of 1850 but I still hit 120% power limit.
