Re: way to use all 8GB VRAM which is half disabled on P104-100 card
The cards have been reflashed many times for safety always with parameters
nvflash64 --protectoff
nvflash64 -6 MyRom.rom
plus a slow card is running with the stock bios (8g unlocked on the PCB)
The reflash was done directly on the rig and also on another PC.
So I assume the problem is not in the reflash.
But thanks anyway every attempt is appreciated
I am now investigating the IRQ assignment

Re: way to use all 8GB VRAM which is half disabled on P104-100 card
ok Alex I tried ... Good results even without overclocking the mems too much ...
But it remains to be seen why half cards go at 35mh and half go at 28mh / s ...
I will disassemble 2 boards to compare the pcb to find any differences ..

Re: way to use all 8GB VRAM which is half disabled on P104-100 card
Thanks Alex I had read about this problem related to the TLB ..
What I can't understand is why with ETH half cards go to 35/36 Mh / s and the other half goes to 28 Mh / s ...
Shouldn't they all go slow or fast the same?
With etc having a lower DAG no problem all the cards go at 40+ Mh / s ..

Re: way to use all 8GB VRAM which is half disabled on P104-100 card
hi guys just wanted to update you on my experiments..
Removing the smd at the bottom right (the one only in the row) I unlocked the 8 giga via pcb and I reflash the stock bios...
Apparently nothing has changed .. and unfortunately, as I already thought, the problem of low hash rate on some cards is not solved ..
I will check how it goes in these days and then at most I modify all the cards (just 5
)
My stock bios, as you can see in the picture, is 86.04.7A.00.02 ... does anyone have if exist an updated stock bios for Zotac?

Re: way to use all 8GB VRAM which is half disabled on P104-100 card
Hi guys .. I wanted to try to compare the pcb configuration of my zotac p104-100 with the pcb of a Zotac GeForce GTX 1080 Mini that uses the same pcb with obviously a different configuration for the 8gb vram.
I can't find high resolution photos to see this area specifically.
Any help is welcome

With the pcb mod you will use the stock bios 
....
compared with en editor .. 226423.rom is the same of 208828.rom ... just last line change (but maybe is important) i'm using it from 10 day ca but nothing is different.
Always sorry for my english

Re: way to use all 8GB VRAM which is half disabled on P104-100 card
...me too ... Now I'm using 208828.rom which is the best of all but more instable.. very high current consumption .. low and instable Hashrate...
I am looking for a hardware solution... but I can't find high definition images of the pcb for comparison

Re: way to use all 8GB VRAM which is half disabled on P104-100 card
Hi Guys .. looking in various forums I read about a solution to unlock the 8 gb of ram with a hardware modification on the PCB ...
Precisely by removing only one resistor (r832) ..
Leaving the stock bios unchanged and solving many problems with power & co.
Unfortunately I have not found anything on the Zotac video cards ..
Anyone have more information about it?

Re: way to use all 8GB VRAM which is half disabled on P104-100 card
Anyone unlock colorful p104-100? Tried a few of the firmware listed in this thread but won't flash. Even the colorful firmware listed on techpowerup won't flash.
I get:
WARNING: Firmware image PCI Subsystem ID (10DE.1237) does not match adapter PCI subsystem ID (7377.0000)
Any advice is appreciated.

For my Zotac i use....
1 CMD as admin
2. nvflash64 --protectoff
3. nvflash64 -6 "MyRomName".rom
Thanks, that allowed the update and I see the 8Gb; however, only getting 20 mh (+700 mem / 65% power) on phoenix miner.
Windows? If so grab one of the mining linux based OS that you can stick on thumbdrive. I prefer mmpOS and for 8 gpus or less it wont cost a thing to try and use. Others are HiveOS, SimpleOS, RaveOS and plenty more im sure i missed.
Currently getting 27mhs out of mine on mmpos
Yeah I use windows but I always have. Something doesn't look right when I compare my gpuz against others. Memory Mhz looks like it's 1/2 of what it should be?

I tried many bios before finding the right one for me.. a lot was power capped or have overheating problems
Now mining only ETC I went back to Stock Bios and now i mining at 40+ mh with 120w
But Thanks i will try to linux based OS

Re: way to use all 8GB VRAM which is half disabled on P104-100 card
Hi guys sorry for my english but i'm an italian guy ..
I have 6 P104-100 from Zotac and I have
flashed the rom 208828.rom .. doing so unlock the 8 gb but my hashrate has a strange trend
What can it depend on?
I have already tried pretty much all the roms on powertech but they are all poweer limited.
