I ran into the same problem the other day after I did the Windows 10 Anniversary Update. The issue comes from Windows removing the required Futuremark SystemInfo service when updating to a newer version. Reinstalling 3DMark should correct the issue.

You can easily solve your power limit problem, especially since your cards are already naked like that. Just put some CoolLabratory Liquid Ultra over the 5MO resistors near the power connectors on the cards. Cover up the whole resistor to connect the two sides of the resistor together. That should about double your power limit on the GPUs.
The mosfets (typically the limiting factor of the GPU VRM) in the VRMs of this card have basically no de-rating with higher temps. Same rating at 25c as 100c. Which is odd for a mosfet, but the reason it is like that is because the package is rated extremely low and is the limiting factor. They do become a little bit less power efficient at higher temps, but they dont lose performance or anything like that on this model. The good news is that the memory VRM current capability is way overbuilt for the memory, can easily put 150 watts through the mosfets (though, 150w would probably over saturate the memory chokes). Just buckets more power than you would ever use. it is surprising Nvidia would build up the memory VRM so much considering how badly they cut costs and make a crap core VRM on all their cards, and because GDDR5X is supposed to use even less power than normal GDDR5. IDK. Maybe the new X RAM requires a more intricate power delivery to achieve its lower draw and higher bandwidth.

I am curious though, how can you claim the parts are not near their T_Max when you dont even know what the parts are called that you are referring to? Seems like you would not be able to look up the spec sheet on something you dont know what it is.
Watercool told me yesterday that the Titan Heatkiller block is being designed. My card performs well enough as is for the time being so I am just going to leave it and wait for the Heatkiller block biggrin.gif
lol - yes, I know they are chokes (I think these are from ON Semi). Never knew one where the AOR and NOR for the part do not separate at higher temps. Above the NOR the part may provide a less stable output - but that is neither here nor there. I did the clu mod to my 1080.
no need for an allen wrench - right? wink.gif

good to see you did the CLU mod. With my bench mounting the cards vertically, the CLU can (and will) just run off and short the card in a spectacular manner. I tried drying the CLU with a hot gun... no help. We'll get a pascal bios editor (hopefully) and these will open up just like TitanXM did. thumb.gif

I had to be super super careful with these. On the KPE I can man handle them and they'd be great ( not saying I did )

Nice Unis! I agree - TXM and KPE - or any maxwell card had a much less fragile PCB.

Oh right? Waay back I had 3 780Ti KPEs and they required a 1200 and a 1500 powersupply to run (but juiced with the EVBOT) AlanCsalt had the same issue with them. I really came to like the "Add2PSU" gadget. smile.gif

Shunt mod tutorial:

Warning: Spoiler! (Click to show)
Warning: CoolLabratory Liquid Ultra (and Pro) are conductive thermal interface materials. We use this conductivity to lower the resistance in the card to do this mod, but this conductivity means it is dangerous and can destroy your graphics card if it spills and touches another component on the GPU. I take no responsibility if you break your own (or someone else's) GPU with this mod. If you choose to do the mod, be careful.




1) Start off by removing the backplate and cooler from your GPU. To do this you will need a size #0 phillips screwdriver and a 4mm socket wrench. Once all the screws and bolts are out the cooler should come off relatively easy, so if it is not coming off then you probably forgot a screw somewhere. Likely places that get forgotten are on the end of the card with the display outputs.

2) Once the cooler is removed your card should look like this:


The three resistors on the card are circled in red. We are only going to mod the top two resistors.



3) Place a small bit of Liquid Ultra on the two top shunt resistors. These resistors have a case label of "5MO". You dont need a ton of CLU, just a small dab that you will spread out. See the picture here for how much I applied:





4) Now use the brush included in the CLU package to spread the CLU over the whole top of the resistors. Be careful not to spill it off the resistor. If the CLU spills off the top of the resistor it will most likely destroy your graphics card. Be careful not to use too much CLU as using too much will cause a spill as well when you put the graphics card back together. There is an inductor very close to resistor #2 (RS2) that can easily be spilled onto. Be very careful with this step.





Your graphics card should look like the above picture now. Put the cooler back onto the card and you are done!

To remove this mod from your graphics card, simply wipe away the CLU. If the liquid ultra has hardened then you may be able to use a hair drier for a very brief period to liquefy the material again so that you can remove it.

I showed a screenshot of before and after the mod in 3DMark earlier to show the mod works. Graphics score rose by 223 points in FS Ultra with the mod. I have now been playing a video game for the past 3 hours since doing the mod and posting this with no problems.



@GunnzAkimbo want to add this to the OP?

well done. thumb.gif

Agreed. TXP will be the best offering for at least 12 months.

Well that sucks as my liquid ultra is arriving today. My cards are mounted vertically, so I guess it is a no-go. I hadn't realized liquid ultra stays liquid enough to literally roll off the resisters. I remember using it with CPU's it would dry hard as a rock and I had to sandblast the stuff off (and why I don't use it on CPU's anymore).

It will dry out eventually, given enough thermal cycles and time. You probably dont have that kind of time or patience for making it dry out on a resistor though. Not even sure those resistors would ever naturally get hot enough to do a proper thermal cycle. You could try just experimenting a bit, put some CLU on a little piece of scrap somewhere and then use a blow drier and some ice to cycle it a few times and see how it behaves after 5-10 minutes of doing that. Probably not near enough time but its probably worth a shot to see how it behaves. If you dont want to try it yourself, I will test out the behavior of the CLU like that next week sometime just to satisfy my own curiosity.

I seriously doubt that too. We are going to see TXPv2 with a fully enabled chip (3840 cores and possibly HBM) very soon. Maybe even December as GDDR5X 1080Ti with 2017Q1 new TXPv2 16GB HBM.
Maybe they'll move to Volta early.
