way to use all 8GB VRAM which is half disabled on P104-100 card

[SpeedY_Hun]

Any info about the Gigabyte cards bios?

[sakalaboator]

Does anyone have a P102 bios with unlocked memory?

Even if someone does... it will not necessarily be compatible with your particular GPUs. The extra RAM may get unlocked, but you'll have various issues with cooling, clock speeds, power limitations, etc.

Aye aye captain! Still it doesn't mean it's not worth tinkering with.

Hi:
   Are you successful? Or have you found the bios for P102 10GMem？ If possible, would you please send a copy for me? sakalawannengbiao@sina.com， Thanks a lot!

wow. share the details, please. thank you

upd. there is a 8 GB vbios on techpowerup - https://www.techpowerup.com/vgabios/208828/208828.
flashed that file to my Palit P104-100s - and it's working, 8 GBs of RAM became available.
but for some reason with this vbios the card starts to throttle itself with soft power cap at 30-40 W, despite showing correct 180W power limit in nvidia-smi output. so overall performance is lower.

cheers m8, i'm currently using HiveOS, which shows no diff with normal 4GB ver. I'll use a hardware power meter to find out how much more power it is using. thx a lot.

Okay, i flashed one P104-100 and it show me the 8GB in Hive OS.
But if i want to mine with that, i get no hashrate.

what`s wrong?

In ETH - i dont see something new. look´s like i get around 1 mhs more. from 38,5 to 39,5mh/s
In BEAM - i got from 8-9 to 18-19 thats good, but not profitable.

I've flash my P104-100 to "8GB" bios provided here but still runs out of ram when launching the DAG. guess it's just a BIOs trick? Edit: Just had to try various BIOs found one that worked which unlocked 8GB albeit it uses more power than before.

Hope it's not off topic but i can't find whether this has been asked before, is it possible that the p106 also has 8gb soldered on board? Currently the p106 is the counterpart of the 1060 6gb and so if the p104 has 8gb hidden inside it, is it possible the p106 has too?

I've read about some hacks to the p106 to make it usable for gaming, so maybe theres one for unlocking more GB too?

P106 is a basically a full GTX1060 6GB there is not further way to unlock it.

Hi, i'm going to try to flash my Asus P104 with the bios 210804.rom

Anyone got more info on how to tune the card after flash?

Your going to use more power so just be careful. Other than that not much. Also that BIOs MAY not work, I had to try a varation of BIOs on my P104s to find ones that unlocked it.

Try one of the BIOs listed here. It doesn't matter that is Gigabyte or not as long as it P104. I suggest using HIVEOS to flash your cards as well.

I'm here to report that - even though the cards flash successfully with a variety of ROMs found >HERE< - they do not function correctly afterwards. Some become too hot, some report vastly inaccurate hashrate readouts, others are stuck on 30W power limit, and others have the fan settings stuck on some value that cannot be adjusted.

Ultimately, they were all limited by power (down to 30W), and had issues with hashrate reporting.

My P104 GPUs are by INNO3D.

   do you still have these gpus  ?

Hello,

I just bought the Asus P104-4g

https://cryptomining-blog.com/9435-first-impressions-form-the-asus-mining-p104-4g-gpu/

I have read on this thread that is possible to unlock the card for a total of 8gb and PCIe 3.0 but then someone reported back that its just a bios gimmick and not true.

Can anyone please verify if we can truly unlock the card and what is actually unlocked and if it comes at a cost ?  ( instability lets say )
Also the card has hidden hdmi and display port connector hidden behind the back-plate are these unlocked with the bios update ?

Thank You
Merry Xmas

100% verified for EVGA and MANLI cards so there is zero reason why you can't unlock yours if they are mining model. You should be able to find a bios pretty easily. I'm sure there are even youtube video's of how to do it.

Also, I can verify that you can unlock P102-100 to 10GB DDR5X, not sure where to get the BIOS but it's definitely a thing on at least some cards.

The new BIOS does unlock the full 8GB but it's sometimes a bad idea for some of the 'mining cards' since the original BIOS sometimes come with custom timings. There is also a diff between Samsung (best) and other brands of RAM. The 42+ mh/s is definitely on mining bios, with custom memory straps, and mining bios.

Sorry for the bit irrelevant post but i just found  2x P106-100 6gb mining cards for 135$ is that a good price ?

The card is this one:

I flashed this BIOS to the Gigabyte board. It was a success, I could mine Cortex with it.

There is a common (AFAIK) problem with fans max revs being about 75% of the stock BIOS and Afterburner does not report memory consumption correctly (always 8192 MB used).

Nice, Good job!  MSI P104-100 works steady 42.8 MH/s. No improvement in speed as before.

Does anyone know, how is it possible to unlock 2560 CUDA cores?

Spec for P104 - Shader Units:  https://i.imgur.com/NROFi4X.jpg

I found this information, that someone wrote:

- 8GB of GDDR5X of which half are disabled via BIOS

- PCI-E 1.1 X4 enforced with BIOS, true hardware form PCI-E 3.0 X16

- Display engine is disabled with BIOS, the I / O ports are actually mechanically functional

- 1920 CUDA cores instead of the default 2560  (possibly all 2560 on board)


Thanks darkneorus!

Hello,

 What driver version did you use?

I flashed my ASUS p104-100 4GB with NVIDIA P104-100 8GB bios from techpowerup. There was a minor device subsystem id mismatch which I overwrote with -6 on the command line, rebooted the machine, and the card is fully unlocked to 8GB with absolutely no issues. Overclocked ram to 750 and getting 40MH/S on ETH.

Hi All

I have a couple of Inno 3D P104-100 4GB. Tried four different 8GB Bios on Techpowerup. All of them open to 8GB but GPU clock stuck at 139mh(30w power cap ) when doing any mining. I've read about this from various forums but by the looks of it this Inno 3D cards is a problem with Bios flashing for not operating like it should. People have seen success with especially EVGA, Asus cards etc and operating as normal.

Now I'm wondering if there might be anyone that has a magical P104-100 8GB bios that works with these Inno 3D cards?

Many Thanks

i think mod the bios manually can be the best solution, i guess to unlock those 4 gb is not too difficult, if anybody would share some info would be better
