I want your GTX460 vBIOSes!

[PiLsY]

-4 -5 -6 on nvflash does the following:

Ignore device id
Ignore vendor id
Rewrite all blocks even if the same


No idea what order dude, just my notes from when i did the 7900gto to gtx flash.

[Ket]

Thanks, useful info indeed Silly how nvidia don't document the -4 command.

[Gaul]

As promised, here are tweaked versions of all the GTX460 vBIOSes I have.

- Max voltage 1.2
- Tables #0,1 0.925v
- Table #3 1.050v

did u use Fermie Bios Editor Lite 1.52 ?

[Ket]

Yep, I've done very little hex work with GTX4xx series.

[cantankerous]

Can this Fermi Bios Editor Lite 1.52 set clocks as well, and what about fan speed? I am DYING over here to set my clocks and adjust my fan slope in the bios so I can ditch Afterburner/Precision Tool altogether. I get screen flashes/flickers when my card jumps between 2D/3D using software and I think setting it in the bios of the card itself would remedy this. I would like to ramp up fan speed to 100% while gaming as it is still relatively quiet. Is this possible? Anxiously awaiting a fully working Nibitor, but nothing on the horizon yet.

[Ket]

FBE can edit clockspeeds, but not fanspeeds.

Do you using software 2D switching because of multi display setup?

This flickering on multi display setups is exactly the reason why nvidia does not full idle in this situation automaticly. This will not change on custom bios either. Its some strange behavior when using GDDR5 and lowering the memory clock while multiple displays are connected. Nvidia stated to this and sayed this is hardware limitation wich isn't fixable!

There are further impacts if you change P3 state memoryclock/voltage to different than P0. This will make impacts on software overclocking and voltage control.

If it were that easy nvidia or some aibs would already have done that. ;-)

[cantankerous]

Thanks for the reply. I suppose I will wait till an all in one solution is complete. I don't want to start ramping up clock speeds just to have the card running hotter than it should because of it. If I have to have software installed to control fan speed, I may as well control clocks as well until I can get a fully tuned bios the way I like.

BTW, what is the most recommended method of dumping the bios from your current card while maintaining 100% integrity. I don't want to flash someone elses bios in the future, I want to flash the exact one that came with my card, however edited. Thanks.

[Ket]

Use GPU-Z to get a BIOS dump, then when the time comes reflash your card from DOS with nvflash.

He hasn't tried it out for himself yet, hang in there

two unlocked msi gtx460's.. seems it works

Hi there, yes, I am using multi display. I am simply raising the overclock via Afterburner from stock 715/1430/900 to 800/1600/1000. Card works fine this way, but periodically, my card will downclock to 405/810/900 and when it does then I get a quick flicker/flash. My card will then jump back to 800/1600/1000. Back and forth this goes. The strange thing is this. Since my card comes factory overclocked to 715, when the card is not overclocked via software, it still down clocks to 405/810/900 and back up to 715/1430/900 but no flickering/flashing. I think it only does it when clocking through software, as without Afterburner managing the clocks, it does not flicker/flash. I was hoping that if I just flashed the bios with the desired clocks and removed Afterburner altogether, this would no longer happen. All I want is fan control so I can set a customized slope to raise the fan speed and I will be set.

@ ket = almost all gtx 460 has FAN LOCK on 70%, could u make it 100 % ? plzzz

[Ket]

Fan lock was with older versions of Afterburner. Use nVidia Inspector, Xtreme Tuner or the latest version of Afterburner and all is fine

By default the fans go to 70% max, this is an update to the card itself. 70% is max on all GTX 460 cards, no matter the card or utility used to increase the fanspeed.

Zotac GTX460 1GB - reference desing, voltage unlocked.

This is the card w/ the DisplayPort correct? Either way thanks.

[Boogerlad]

I wonder if it's hard to unlock the extra shaders... Hex editing is hard for me though.

[Ket]

Does anybody own a eVGA GTX460 1GB? I'd greatly love to add that to my collection

@ gaul, you can override BIOS set fan profiles with any of the softwares I mentioned, not a big deal. FBE doesn't have the ability to change fanspeeds, just to change GPU / memory speeds and adjust voltages.

[cantankerous]

though I unfortunately don't have access to Fermi Bios Editor Lite, from the screen shots I have seen, I wouldn't know where to start on setting my clocks. The multiple tables with all the values completely throws me off. It isn't like Nibitor in the old days where you had 3 boxes, core, shader and mem and you simply typed in your values and voila. How do you go about reading all the tables and know which values to change and which not?

[Ket]

The values do throw you off to start with you need to look at the tables and see what does what. FBE doesn't seem to show you GPU speeds in the classic sence either, instead giving you shaders values to change (GPU and shaders are tied) along with the obvious memory values, FBE also chooses to show you more obscure settings such as maximum shader limits, which you can also adjust yourself. Some values are still a mystery even to me, the boxes don't seem to follow any set pattern. EG; Whats a maximum shader value for one P-State isn't in the corresponding box for another P-State. I also advise those who do have FBE to use voltage entries 0 and 1, NOT 3. For some reason 3 just doesn't work. Voltage value 0 corresponds to bootup/2D (probably UVD clocks too), while voltage value 1 is 3D voltage.

Thanks for the explanation. I have found this little write up from a member of another forum, and it seems to make much more sense now. Although 90% of the values are still unknown, at least you know which ones to look out for and change for basics such as 3D clocks. It relates to Nibitor 5.6 mind you, but perhaps you can get something from it. Sadly, no fan support which is what I would really like.

AFAIK nibitor 5.7 won't support GTX460s, but they are working on that. IMO nibitor struggles to support new hardware these days, it relies on a engine and methods that were compiled 5 years or more ago, the whole application could do with rewriting from the ground up so it has a nice versatile engine like RBE does.

[cantankerous]

as far as I have read, the Nibitor which does support GTX 460 is currently done, but only accessible through donation only for the time being. It will be released publicly after that. Still no fan support though, that is still being worked on. I will wait and flash my card in one fell swoop once everything is 100% integrated and with full fan/clock/voltage support.

[Ket]

Good to know. They seem to really be struggling with Fermi support and I'll keep whipping it because I believe it to be true. Nibitor uses a very old engine, it needs updating to something flexible like Radeon BIOS Editor uses to make supporting new hardware much easier.

the gs bios has p3 states,while others dont have it?
i do not really understand all of this differences.

on monday i look for evga bios.
