GTX 660ti Owners Club

[LPC Paulus]

Just to note all BIOSs I unlock will feature the following:

1). 300 watt base power limit. This should be well beyond the possibility of ever reaching this limit. Please note that this will make your card run at the max boost clocks during gaming and/or benching i.e. no more throttling.
2). Unlocked 300+ over the new 300 watt power limit just in case you find a way to exceed 300 watts.
3). Voltage set to the max bios limit 1.215v
4). Fan RPM range set to %30 - %100

Hi CrazyNuts!

Nice info on the unlocked bios!
Just for your info, my card starts at 10% fan duty cicle, so its better to do the range from 10% to 100%.

Another question, unlocking the bios, does alter the fan spin cicle? The asus profile in bios is just great, starts at 10% and go all the way up to 50% i think, stabilizing at 70c. Thanks in advance!

I'll have to play with the fan a bit. I fear that if I set it too low on some cards the fan may not start initially.

For now I can take requests for fan speed settings.

hey crazy, went to try to flash the bios of my card today, downloaded the nvflash you posted from TPU and tried running the .exe as an admin, and it pops up, asking me to press enter a bunch of times, then eventually, the program closes.
ive also tried pressing N to start the nvflash command as well as - to try the update command, but its doing the same thing and closing each times.
am i an idiot or is there a trick to this?

__edit: nevermind, i got it to work, had to run the exe from command prompt.

[CrazyNutz]

Can you unlock my firmware.

Thanks

Hi M8!
Well It seems this card is not getting the attention it deserved...

I just bought last week an Asus 660Ti (normal) and have it flashed for the "new" bios released by Asus to up the voltage and power limit...

But i think it will be possible to extract a little more juice out of her...

Can you unlock this sucker?
I attached the bios that is on it right now!

Thanks in advance...

Voltage and power unlocked. I left the fan at 10-100. Enjoy!

Hi Crazy!

Im going to flash it today!

I will then let you know if everything went well!

Hi again!
Just tried to flash the rom, but with no luck... it says its locked for reflash...



How can i bypass that issue?

Thanks in advance!

LPC

UPdate: I just got it with the commands... Run Nvflash --protectoff and then i flashed

[LPC Paulus]

Hi!
Just Flashed the Bios...
Here are the first results...



From what i see, the asus software is not reading right the parameters...
Talking about voltage, power limit and minimal base voltage or something...

Any ideas?

Best Regards,

LPC

New here but do you think you could unlock the voltage/fans on the 3GB Galaxy, I run these in SLI and have a nice OC but they cap at 1.17 on the voltage. It would be nice to see if I can push them higher. temps don't even hit 60 stressing these things.


Thanks

Really nice work Crazy.

This is an EVGA like yours. Can you drop the fan speed min to 15% or 10%? and any other sweet tweaks you deem necessary. Im going for a silent card so keep that in mind.

Thanks

I'm running an EVGA 660ti SC as well. Mine's not too much of an overclocker though, doesn't seem to want to go past 1215 boost no matter how cool I keep her.

Set fan min to 15%. I could also lower the voltage if you like?

Same with mine really. I thought it was stable at 1250, until I tried bordelands 2 with physx turn all the way up.

I think you really need a non ref board to max these things out.

Thanks for the galaxy bios, the non ref PCB is the only reason I went with this card, that and the 3 gb of memory. as of now before bios flash I am at 1202 on the core and +700 on the memory clock! If I can figure out this NVflash I will let you know how it goes!! LOL! I am a builder and hate programming side of CPU. Thanks again!

OK please help! this NVflash says to hit enter to continue like 5x's then closes on me! my buddy uses some weird german version of zotac firestorm and flashes his bios on his 680's in mere seconds. I have no idea??? Can someone help me with out being a tool! I would greatly appreciate it

everything is fine, i made the same mistake. copy the contents of the nvflash folder and your rom to be flashed inside your user folder c:\user\whateveryournameis. Now use cmd and type nvflash yourromname.rom
then reboot

[ajax1000]

Set fan min to 15%. I could also lower the voltage if you like?

Really nice so far, have a look at my rig and the idle results. Id like to bring this fan to 500 rpm at idle and since the fan is controlled by the card i dont have to worry about overheating. The fan is a nexus pwm real silent and its the only moving part in my system.

Actually if your using the nvflash I posted, you can simply drag and drop your bios file onto the nvflash.exe

However sometimes your bios is write protected so if this is the case you'll have to do it from the cmd line

[oOEvil1Oo]

Yeah, I feel like a tard, right after I posted that I figured it out on accident. Oh well if you guys running a single card are wondering how these scale here is my screenshot from 3dmark 11. I will post a heaven score shortly

[oOEvil1Oo]

Here is the heaven score, the temps on these galaxy 3gb cards is great. still below 60 running heaven/3dmark11

I love my Galaxy 3GB, I can also attest to being very impressed with the cooling.

I'll have to give the OC'ing a run soon and post back here later... thanks for all the info that you've all been posting here!

Hey crazy nutz, Just noticed these galaxy cards are temp. throttling at 70 degrees. is there a way to fix this? My buddy just put 3 of them in his system and the top card hits 70 and downclocks? Please let me know or if its a tweak in the modded bios can you post that.


Thanks!!

Yep mine does the exact same thing. I might be able to fix it. Let me play around with it a bit and i'll let you know.

[oOEvil1Oo]

Thanks, I am curios to what his final setup runs with three of these, my two cards run great... I know his early bench runs have been great and he is running 5760x1080. My monitors will be here today so I can see how 2 cards run on 5760 resolution!
