Introducing the Nvidia GTX 1080 Ti



The GeForce® GTX 1080 Ti is NVIDIA's new flagship gaming GPU, based on the NVIDIA Pascal™ architecture. The latest addition to the ultimate gaming platform, this card is packed with extreme gaming horsepower, next-gen 11 Gbps GDDR5X memory, and a massive 11 GB frame buffer.

The link goes into a lot of detail on exactly the best way to get an overclock with little or no power limiting using a custom voltage curve.

How to get an unlocked voltage slider.
Warning: Spoiler! (Click to show)
Afterburner 4.4 beta works out of the box from link below, just download and install it, voltage slider will be unlocked.

Go to c:\Program Files (x86)\MSI AfterBurner\
Open MSIAfterburner.oem2 in a text editor and add the card to third party database yourself and save at the very bottom of all the text in the file.

[VEN_10DE&DEV_1B06&SUBSYS_120F10DE&REV_??]
VDDC_Generic_Detection = 1


You will notice the part bolded, the Subsys_ID. This can change per BIOS/Brand. In AfterBurner just click the 'I' (information) button, to read out your proper string and replace the bolded part with what is listed under the information button (if it differs).

Afterburner select third party voltage control mode in properties and adding the following will do the trick.

Just replace the text between '1B06&' and '&REV' from the 'I' Info and leave the rest as is from the 'I' (Info) button in Afterburner.

So for example and EVGA Ti FE the 'I' button says.

[VEN_10DE&DEV_1B06&SUBSYS_63903842&REV_A1&BUS_2&DEV_0&FN_0]

So for EVGA in the .oem2 file in the MSI Programs folder right at the very bottom of all the text in the file you add:

[VEN_10DE&DEV_1B06&SUBSYS_63903842&REV_??]
VDDC_Generic_Detection = 1

Reference cards should be and most others should be

[VEN_10DE&DEV_1B06&SUBSYS_120F10DE&REV_??]
VDDC_Generic_Detection = 1

I'm adding .zip files for reference cards and EVGA here.

Right click on zip, choose Properties, and Unblock, then unzip.


Try this one first.

WildCard.zip 1k .zip file

If not, this one.

MSIAfterburner.zip 1k .zip file

EVGA, this one if first one doesn't work.

EVGA.zip 1k .zip file


Afterburner select third party voltage control mode in properties.

If you click the cog icon, make sure Enable Hardware Control and Monitoring, Enable Low level IO Driver, Enable Low Level Hardware Access Interface 'Use Mode', Restore Settings After Suspended Mode, Unlock Voltage Control 'Third Party' and Unlock Voltage Monitoring are all checked.

Download it here and replace the '.oem2' file with the extracted WildCards.zip.

A shunt mod story by SlimJ87D
Warning: Spoiler! (Click to show)
Unlocking the FE's true potential

After hitting power limits, I could not take it anymore. I knew that it was time for be to do the shunt mod. My card could bench at 2114 Mhz in heaven, and I believe it could go higher. After all, I've seen it boost to 2138 Mhz before without crashing.

I found it as a OC member, it was irresponsible for me to have so much potential thrown away. My theory was that I had a pretty nice golden card. That theory was proved to me today.

What I needed to prepare for

The shunt mod, if done right without too much CLU, will drop your 100% to 75-80%. This means that at 75%-80% you are drawing 300-310 Watts.This can be dangerous because at 120%, that is 450 Watts!

Because I set out to perform this shunt mod, I need to upgrade my cooling. My x41 was nearly at its limits. The liquid temperature was at 40C and my GPU temperatures stock was at 48C. If efficiency was 100%, then liquid and GPU temperatures would be equal according to newton's energy equation. Thus, I knew there was things I could do.

1. I could improve the TIM in between my shim and heat pump. Originally, I was planning to CLU the die and other side of the shim, but after looking online, CLU is really bad for dies from a RMA stand point, it leaves stains. So I decided to just use Gelid Extreme on the die and CLU on the shim and pump. Eureka, this got liquid temperatures from 40C to 44C, this means that more heat was being transferred to the radiator.

2. The midplate is a heatsink itself. It is connected to VRMs, VRAMs and other components. If I was going to introduce more watts to this card, I need to keep them cool. Originally I had placed 8 heatsinks on my midplate. This dropped my core temperature from 51C to 48C. Taking thermal measurements, the shims were at 36C. I knew that if I added more heatsinks, specially closer to the VRMs, it would help with the extra 50 to 75 Watts.



3. Finally, the backplate was not absorbing any heat whatsoever. The aluminum plate is somewhat thin, my theory is that the plate was too thin to absorb heat from the GPU, it would cause warping and flexing. But using my engineering knowledge and deduction, I knew that my AIO was keeping my GPU at 48C, so 45-60C wouldn't harm the back plate at all. So I added a thermal pad in between the back of the GPU and the backplate.




The shunt mod

For my shunt mod, I used CLU and liquid electrical tape.





My results

My previous calculations were correct. From the shunt mod, running a light heaven, I was drawing 300-310 Watts at 75-80% power draw. That means at 100%, I would be drawing 400 Watts.

At max, my card was drawing 95-100%, which mean I was drawing 400 Watts. This is confirmed below!



Here are my thermal results

Stock at 300 Watts, 48C.

Shunt modded at 400 Watts, 50C

All my modifications have successfully fought off the incoming 100 Watts.

After some light benchmarks, I can easily hit 2152 Mhz @ 1.093v with no limiting.



I have decided to call it a day and spend time with my wife. I have not pushed this card to is maximum core clock yet.

With great power... comes great responsibility... Conclusion

This card is now drawing 100 extra watts, which is very dangerous. Because I do not want a $700 paper weight, my next step is to find a balance between my maximum core clock and voltage and try to limit my power draw to 350-375 Watts.

Do I recommend this mod?
To people on water, yes!

To people on AIO, maybe. You must take the extra steps I did to ward off that 100 Watts of extra heat that will be coming to your card.

To people on AIR, No. I do not recommend this mod to people on air. It can potentially be dangerous.

To people with partner cards. Maybe... you have to think about it, you're adding 33% more power and that can increase your temperatures by 33% as a rough estimate. It can be counter productive due to thermal throttling. And if you don't take extra pre-cautions to cool your card, it can blow up!

I don't. this is my 1st pre order with them. I did see several shipping options available. I choose the standard one since i'm not in a hurry.

I think I read that pre orders will start shipping on the 10th, I can't seem to confirm that. This is my first pre order as well.

Sad to report that pre-orders are now sold out at NVIDIA. Did not last an hour!

Woo I am glad I got into the preorder when I did. Contemplated getting two but decided to hold off to see if amd releases something more powerful to pop over to that. Having 290x's I can't wait for the performance increases. Ordered standard shipping as well.
post #8 of 7233
I almost got 2 as well, but I figured that it was way overkill... plus that is expensive!

Plus we are both nice guys and gave 1-2 other people a chance smile.gif

Ordered 1 as well with next day shipping. Should have gotten 2. I'll be selling it anyway once evga comes out with theirs.
