NOTE: The same BIOS for multiple GPUs?

my g1 is 80 c in load...ysterday i reaply thermal paste to mx4 and new pads...its still the same temp i have custom curve
is the temp too high?
what to do?
dont like to play with water.

80c in load for a G1 970 is pretty bad, you are nearing the hardware thermal limit.

Flashing that "SC" BIOS seemed to show that the power limit had been increased (also evident by memory overclocking having an advantage since O/C memory uses a lot more power). It could technically allow a higher boost if the reason the GPU couldn't boost higher was PWR perfcaps. Having said that, I would agree with you that flashing that BIOS would just allow you to stay at a higher boost, longer and most likely not provide any additional O/C headroom.

Once we can get to the voltage I think this will change potentially however the way things are looking voltage may not help Pascal much.... and if it DOES it might ONLY be under H2O or better cooling (we already see that Pascal runs very hot, even hotter than I think GM204 was)..This is a bad sign for voltage and AIR headroom...


I try playing around different bioses i even flashed 8+6 pin bios on my founders like i told you in the other topic..

For the first time i saw red dots/graphical errors (core related) on my 1080 which i never seen before on stock bios instead of a instant crash pwr limited crap..

Power limiting is reporting way below what it should, but i think is reporting only the 8PIN/pciex power draw and not the 6 pin so the reading its fine and dont affect the gpu. it doesnt have the 6pin and is not going to request more of something it dont have on a hardware level... Extra vrm phases have nothing to do here other than cleaner power supplied to the gpu which in this gpu seems useless with the low voltages ...

I got more room to play but you need to keep that core cold.... The mem overclobability is a placebo i got mine to do 800+ mhz that dont mean it performs as such, error correction kicks in .. Im still playing with it learning this gpu top to bottom.

I have very good success and stability with the EVGA SC Bios (1x8pin) on my Zotac founders. it behaves like it is tweaked no throttles no nothing other than the bios set throttling points every 10c.. I have a hybrid mod on it and the low rpms on the fans dont affect me.

I dont think the voltage would help us at all..

Im achieving the same overclock in 1.012mV as on 1.093mV
At least in maxwell i could get 155 mhz extra with that kind of bump

Ghetto cool tech to the rescue smile.gif

Max temp is 91C so you're OK but that is hot, you should be able to improve airflow and add supplemental fans to cool things down.

Agree... it's not looking good for MOD Pascal...

This is with the core under 40c...

jmpboy have the gpu at constant 32c with his water chiller and hes able to achieve 2.2 but this is on valley only if im a correct..
Im able to achieve 2114mhz stabe constant on fire strike.

The trick would be locking your voltage as low as possible using the curve and save those few watts for mem overclocking and to stop hitting 120% and throttling and crashing.

Bios mod would still be helpfiul in leveling all that stuff few extra watts from pciex and 8pin and maybe 50mhz more on core, this cards dont like more volts or the fluctuation of them ...

I suspect VRM temps are just as much of an issue on Pascal as it was on Maxwell under AIR (the AIO coolers w/adapters for GPU do not watercool the VRMs...They are hybrid designs). That means there is a LITTLE hope that a full cover block could provide O/C headroom... but definitely requires a modified BIOS.

Despite potentially not having much O/C headroom on Pascal there are still going to be a lot of benefits of a MOD BIOS, primarily with removal of perfcaps and throttling... so all hope is not lost. redface.gif

Wow only 264mm long. That should fit some small cases providing you have room for the rad. It doesn't look that short.

and if you want/need the 2-slot solution you gotta pay....might be why all of a sudden xtreme air became 3-slot headscratch.gif

Big changes from Maxwell....
