No, the TDP should be the 3rd from the bottom (265000). 175 is a bit low. Whatever you change TDP to should also mirror your first entry. I would leave Def and Max the same numbers as Teslas don't have TDP sliders on Afterburner/X1.

What you have marked is probably 8 pin rail. The one above that (66000) is slot and should be changed to 75000

It is hard to tell as the pictures look like an already modified vBIOS. Do you happen to have the stock one? Or is this one bone stock?

That vBIOS I linked seemed low for TDP

Yes, the BIOS I sent is already a modified one. The Tesla K80 is a Dual-Gpu card. it's suppose to pull 150 watts per "gpu", for a total of 300. Right now I'm just trying to edit the first GPU, not the 2nd one.

I can upload my stock one I saved from GPU-Z.

I am aware it's a dual GPU card, I have owned several. There is no way to segregate the vBIOS per GPU. It's just one. You can't modify a vBIOS for each GPU. If you can, then I was not aware of it at time I played with Keplar bios tweaker. Can you show pictures of the stock vBIOS?

 

[Avacado]

It is possible, bust shouldn't matter. Both GPU's pull from the same 8 Pin and same slot. If you look at the tech power up site, it lists the card as a 300w TDP and does not segregate it into 150w (Per GPU) even though the card does it on it's own.
For a somewhat safe trial (Validate with GPUz) I would do 1000/300000/300000 on Power Limit, 1000/75000/75000 on slot and change TDP to 150000/300000/300000. The 8 Pin rail at 100000/149000/175000 is already pretty good. It has been my experience with bios tweaking that you very rarely get the wattage you are seeking with the modifications.

Have you personally had any luck OC'ing the Tesla K80? I feel like if I can get temps down, 1100 - 1300mhz is possible, very similar to 780ti / titan

Yes, some. I had more successes with the M40's. Because they are passive, I had to integrate 3d printed blower coolers that used double sided tape to secure on the top of the cards. They worked very well after re-padding of vmem and re-application of TIM on the die.

The only Tesla I have currently is the GRID M40 (4 GPU) and I can't find any drivers that can run it currently so I haven't played with it much.

@Avacado
Still seems like I'm limited, even though I raised the limits, lol

Even maxed out the slider in afterburner

It's what I was expecting TBH. Is that Board power draw for both GPU's or 1? 154x2 is right at TDP of 300ish for the card. There are a few things you can do at this point. Increase wattage on the slot/8 pin rail/ TDP and power target. Or you can try to increase voltage, which will help a ton if it works.

Power limit increase to 450k, TDP to 450k. slot max to 80w, 8-pin to 300k. My bet is you might see a slight increase in wattage, but not much. You are going to need to play with voltage to see any real gains from this card. I can help you there if you want.

Run a torture test and show GPUz tab for voltage max.

 

[Avacado]

That's only for 1 gpu. Other one is currently disabled. Running nvidia-smi shows another story though. It shows that 185 watts is the max tdp, but it's not using it?

Also, it's only using 1.0v exactly during stress tests.

Ok, cool. Yea, 1.0v is very low. I would be totally comfortable running up to 1.2v daily. I even push 1.35v on some Keplar/Maxwell GPUs for benching.

185 Max TDP doesn't make sense as none of your wattage parameters are set to that.

 

[Avacado]

I just fixed / edited my comment to show you a picture. Yea, that's super weird.

EDIT: The value that I set to 185k, that you thought was the 8 pin, is actually the TDP. I raised it from 175k to 185k, and that's what nvidia-smi is reporting. You may have your 8 pin connector & TDP mixed up. Underload it's actually more like 0.93 - 0.95 volts, not even a full 1.0v

OK, that works. Still a weird value though.
