We followed the instructions from our trusted manufacturer and flashed an optimized BIOS designed for mining memory-intensive algorithms such as Ethash. The BIOS runs a set of new memory timings that suits this particular model's GDDR5X 4GB memory chips.
How did they flash Nvidia card? Power limit is capped at 135W but TGP is listed at 180W-225W?
Dunno about the BIOS part. I think the 135W cap is done using nvidia-smi function in Linux. Just a single command.
I really want to get my hands on some, but china has of course priority and theres almost no cards left for the rest of the world.
Yeah, seems like all P104-100 are in extremely short supply. The $620 price point seems alright given it's a 40MH/s card. Even a $1,000 1080 Ti can't achieve that kind of performance.
No one should mine Ethash with 1080Ti. Right now 40MH/s is $4/day while 750Sol/s is $6.5.
True, agree with you on the ZCash profitability part.
