wait nvidia they actual released tool for this? or your just using stock nvidia picture?, Nothing bad can happen from this nothing bad at all. Usefull to the people that know what they doing and know how to READ before hand.

I don't think nvidia released this, it's done by hobby overclockers. Like mentioned JoeDirt for instance, there's a couple of hundred pages on Maxwell overclocking on overclock.net where you could read this up. And yes, with the wrong BIOS you can brick your card, make your rig not boot, push in too much voltage etc. like tsunami said, definately you should read into it.

Question: I have a Zotac nVidia 970 standard 1076 Clock, 1753 Memory. The bios is 84.04.1F.00.6B What are the pros and cons of updating my bios? Sounds dangerous but intriguing. Thanks

If there is a updated bios available for a GPU then as far as I know it's usually tweaks to stuff like voltage, fan speed curves and other small fixes and improvements although it can vary from one manufacturer to another and also depend on if it's a stock GPU or a more customized third party design. (Some manufacturers also release bios updates more regularly than others whereas in some cases new bios revisions have to be dumped from new revisions of the GPU and made available third-party via say I think it was TechPowerup that had a GPU bios database to name one.) (Though you want to be careful if using a dumped non-official bios just in case it wasn't dumped correctly or if it's not appropriate for your GPU so ideally if your GPU has a bios switch you can revert to default by switching that or even dump the original bios and re-flash if it goes badly.)

I don't often flash the GPU's bios so I'm not very knowledgeable on how it all works and best practices and such though one last bit of advice is to be careful if you do it under Windows as some of the available flash utilities might work as intended only in a boot-loader / "DOS" environment to be able to fully restart or access the GPU device although by now I'm sure there's well tested Windows versions too, maybe this is one of them so it might not be as big of a issue these days. (Same with motherboard bios updating although these days with USB nearly automatic bios management / flashing on newer boards it's much easier to do.) Last GPU I flashed was a AMD 6970 where I had one of the faulty models with incorrect clock speeds set, turns out (I learned this later.) that the 6970 was locked so flashing the GPU nearly bricked it if it hadn't been for the bios switch this model had.

Never flashed a GPU i think. I have been thinking about flashing my asus 1080ti oc to a Poseidon firmware as it runs a little faster still. But a good firmware is hard to come by?

If it ain't broke leave it be. https://www.bing.com/th?id=OIP.BljEBStmNEsZxEr13O9SoAHaG6&w=150&h=140&c=7&o=5&pid=1.7

From both links I get old version 5.556.0...

As I said, I get neither but the old 5.556.0. And the dates of the .exe files are 13.03.2019. So the links are not OK.

Links are fine, files are from end of oct 2019, not march.

That is because they are not the same files anymore, the were corrected in the links. I first had files with the old date 13.03.2019., and there was a nvflash.txt file (with important Commands and other info) that also said version 5.556.0. inside, now there is none. And now the new date of files are 29.10.2019. and version is now 5.590.0. As lucasfrance said, the post title is still wrong..

Isn't that thing with 8 fans the rad and not the res? 😉
