Asus P104-100 4G mining card hack to GTX 1080 possible?

[masterdeejay]

I have bought a cheap ex mining card for 60 usd. The seller already modded the vram to 8Gb with bios (the 4G card mod to 8G is very common for this mining series). I can game with a modded asian driver but still limited performance because of the low 4x pcie mode.

The PCB is the same as the Asus GTX1080 Turbo. Vram is GDDR5X 8x1GB (from Micron spec pdf)
Is there an unlocked bios for this card?
First i need to fix the pcie lanes.
It is pcie 16x physically (all traces are good, and there is enough smd capacitor on the lines) so i think it is just bios limited.
I don't care if the outputs not working.
I have Ch341a programmer just don't know that bios to use on this card. It is indeed a GTX1080 turbo, and i think it is the full GP104 GPU (according to Asus pdf spec).
This is a fun project, i have another card for gaming (Intel A770 16Gb) so it is no big deal if the card is dies in the process.

Ah, okay, I admit that I didn't read the whole thread.

Just weird that even Nvidia has their own name on cards like these, I thought that these are from manufacturers.

Nvidia makes all the silicon, regardless of who "makes the card". Every card you buy outside of the direct nvidia brand, is essentially a mod made by the approved nvidia partner, to the "reference" design. This is why nvidia base model cards are called "reference" cards. This is also why the industry refers to asus, evga (r.i.p.), gigabyte, etc cards, as "board partner cards". The difference in a standard "reference" 1080, and a 1080 FTW hybrid for example, is not much. EVGA selected their components, made their own board, (basically a copy of the reference board) made their own licensed signed, higher wattage limit bios, put a AIO cooler on the gpu die, and boom, "better" new card. The coolers will even swap from one to the other. This is great for people who want a higher power bios, and have better cooling on their reference 1080, as it is essentially the same card. I am one of those people, my cards are full block liquid cooled, and that bios runs like hot butter on them. The EVGA 1080 FTW classified however, is a highly modified board, capable of much more power. (220w if I remember right) It still has to play by the baseline rules of the gpu chip for I/O, but it has the capability to provide more power to the die at a much cleaner and stable state. These low run partner board models also (this might be just a rumor) get "binned" silicon, these are gpu chips that out performed their siblings in testing, are placed in a special "bin" for sale and should in theory provide higher overclocks/more stable performance. On the flip side, if the chips can't make the standard for the reference design, they can be "cut down" (disabling features, cuda cores, or other things) to be used on lower tier cards. Many believe that is the case for the mining cards.

All that said, falcon is a reality of ALL Nvidia chipped GPUs since the Maxwell architecture was implemented. This is regardless of the board it is run on.

CMP 100-210 info from other forum:
16Gb vram unlocked, all cores and tensor cores are there. (5120 shader and 640 tensor core)
Pcie limited to 1.1 1x-4x
Double precision is crippled.
Compared to P100

Very interesting, does it have NVENC though? Same question for the other mining cards.

Interesting what they did to double precision performance though. Idk if they nerfed it because this is a defective chip that never could've been a V100 or they just wanted to make it ever so slightly less useful... It's essentially been brought down to consumer card level performance, and yet single precision still kicks ass and is only a little weaker than a full V100. The numbers are suspiciously close to a 2080 Ti, even though it's a different architecture: https://www.techpowerup.com/gpu-specs/geforce-rtx-2080-ti.c3305

Another thing you could try, go to nvidia control panel and try to enable "Double precision" under 3D settings. Back in kepler days some Titans shipped with lowered FP64 performance out of the box because it impacted FP32, but you could re-enable it in settings.

Just don't buy this card.
Probably some chinese scammers selling P104-101 as GTX 1080.

From reddit: Chinese GTX 1080 GUIDE (NOT RECOMMENDED/DO AT YOUR OWN RISK) , read this thread.

plus, if it is a P104-101 it will only have a PCIe 1.0 X4 interface according to the GPU database.


It can be done with some "3rd party patch and certificate" apparantly , for using a Crypto Mining Processor GPU for graphics.

=> How to use Miner GPU as Gaming GPU , of course one needs to know the card model , and the equivalent to turn it into.

But Nvidia doesn't want CMP GPU's be used with NVIDIA Development Tools.

From a previous topic here on TPU, maybe there is useful information for your GPU in the links.

I bought a Chinese mining card that i can't update the drivers therefore i am stuck with 2017 version.
Can anyone help me with that

How it is detected in GPU-Z, is chip GP104? Does it have working video output? Post screenshot of first page.

If it is GP104 with id 10DE 1B80 but does not accept modern drivers - it is a engeneering sample GPU that was banned by Nvidia in windows driver after certain update. However It works fine with Linux (NOT banned in LInux official driver).

Also you can try the latest modded driver from https://github.com/dartraiden/NVIDIA-patcher or from https://raincandy.tech/nvcmpgpu/ (same at https://pan.huang1111.cn/s/7GqEHg ) but I'm not sure if it helps with such GPU.
Those drivers would have some signature problems/anti-cheat conflicats but are at least newer

Thanks alot for the links I'll try modded versions

I have a gp 104 gtx1080 that's stuck on 377.35 driver version
Can anyone plz provide me with a newer version
