bathrobehero,
What is the advantage for mining when increasing the TDP of a 750Ti via a flashed BIOS?
I imagine that it allows a higher overclock and therefore higher hashrate. But, I have had a PNY 750Ti OC for over a year, and I never flashed it. I never saw anyone posting any hashrates for algorithms that I cared to mine that were significantly higher than what my card would do (with my particular card's stock BIOS - OC maximized). Sure, maybe a less than 5% faster hashrate than my card, but that just didn't seem worth the risk and effort.
Am I correct or mistaken?
It's both higher overclock and more stability with overclocks. Even though I'll never get how some people can overclock their 750 Ti cards to ~1500 mhz and be stable, with increased TDP I could overclock to around 1350-1380 mhz and still have the rig running for weeks without crashing (for most algorithms that is). I always ready to jump onto new coins and solomine as much as I can until the pools join and the difficulty shoots up so I appreciate higher hashrate over hashrate/power consumption figures.
Just replace the bios with the gforce black bios. Same cooler, same power setting, more hash
Never heard of it but I don't think that is any different from a TDP mod. I just think the voltage regulation modules on these particular cards are just not equipped to handle anything over stock figures for long periods of time.
