I know 1080's are capable of that but I've never seen a 1070 go that high! Where are you getting this reading from?
A GTX 1070 is supposed to have a 151W base power limit and 170W (100%-112%). Just for reference, 152% is *230W*.
Find out what the base TDP is at 100% for that card, please and what wattage it is actually using.
The newest version of MSI Afterburner should be able to read the wattage. if it can not, use HWinfo64 (it even has a RTSS plugin overlay so you can use it with RTSS). HWinfo64 will show the exact wattage the card is pulling.
I'm 98% sure a GTX 1070 can't go anywhere close to 291W TDP without voltage adjustments. You would need to really crank up the voltage for that. It definitely can't do that at 1.031v for sure.
291W TDP is modded GTX 1080 territory. You mentioned "126% TDP". 126% from a 150W base is exactly 200W.
Yes, the stock BIOS for the GTX 1070 Gaming X is 230W at 100% and max at 126% = 291W. NVSMI log of my card attached, this is when set the power limit at max with either Afterburner or NVSMI.
Can be seen in the TPU hosted BIOS as well: https://www.techpowerup.com/vgabios/...70-8192-160602
was running a very similar BIOS with his card, the 1070 Gaming Z BIOS that is: https://www.overclock.net/forum/69-n...l#post27352001
Has the same 291W max limit, and he saw throttling at 105% = 242W. Mine hits the power limit flag at ~104%, which should be ~239W. Regardless of the fact that Afterburner and NVSMI show the current power limit being set at 126% / 291W. And maybe the weirdest thing is HWinfo showing max wattage being only at ~211W!
The normal troubleshooting has been done, aka DDU-> clean reinstall of drivers and Afterburner etc... Nothing changed. Weird thing, had nothing like this ever with my 1080 Ti.
That is exactly where the conundrum is. The BIOS should have plenty
of headroom, but refuses to use it.
