GTS450 BIOS Mods

[CrazyNutz]

Yeah my mobo supports gen. 2.0 and in my bios i can force it into gen. 1.0 if i wanted to to its a BioStar H55A+ 1156 socket i hate it only got it just so i have a pc to use till i get my new one i had to sell my other one cuz i needed the money at the time it was an ASUS P7P55D-E Turbo Evo Mobo a hell of alot better than this BioStar im using now. But i did save my original i just have to remember what i did with it but if you can help me with this one for now i will be very happy and take your time bro if you need to i got maaaad faith in you bro!! But i did get my card to show back up in pci-e 2.0 x16 @ 2.0 x16 in GPU-Z but the problem i am having is that the clocks slow down when im in game and even after exiting the game and restarting it it still stays in the low 2d mode it doesnt go back into 3d mode for some reason but what ever you can do for me man would be awesome even if you have to put everything back to stock then go ahead and do that if its easier for ya well i mean quicker for ya lol cuz i know your good at what you do!! Oh and in GPU-Z im still getting that i only have 7.7GPixels of Pixel Fillrate my Texture Fillrate is fine???? Sorry for the rambling lol

If it clocks down during gaming then the overclock was not stable. This is common. You need to flash the orig bios back to the card, and figure out what the actual stable clocks are. then upload the bios and let me know what you want changed.

Also you need to know that the card may have once been stable at some clocks, but then it became unstable after some time. This is degradation. It's something that is real and we have to live with it. My best advice is to find your max stable frequency, and then back it down a bit from there.

Hello is it possible for the fan to go below 30% ? I Have an EVGA 450GTS

I would like my low 2d clocks to be upped to 850mhz fore the core and 1700 for the shader and 1800mhz on the memory my current clocks are gpu/shader/memory---960/1920/1950 i dont care what it does to the card i have backups and onboard hdmi on the mobo so i dont want NO low clocks so up all the low clocks that are suppose to clock down just turn them all up and set my fan settings to min. of 100% like i said i dont care what happens to the card lets experiment make all the low downed clocks upto where i want them set if you can do that for me bro that be great!! And put the max voltage limit to 2V please!!

Hi guys.
Just got my first 450 and hit a wall at around 1015 MHz@1.162V.
It's the non-Cyclone MSI and I don't think somebody already asked for the 1.2V BIOS, so if you got some free time, I'd really appreciate a mod.

Thanks in advance.

@Burningz

Here is the modded bios for voltage unlock. I'm not sure it will work but give it a shot.

@CrazyNuts can i get my Bios unlocked voltage and fan, my card is a zogis gts 450 and here is the bios:

https://www.dropbox.com/s/zosklfnrhkylcdy/GF106.rom

Voltage unlocked to maximum allowed. Fan speed range adjusted 10 - 100%.
Not sure the fan adjustment will work though.

[popifty]

thanks let me try

[popifty]

fan adjustment works perfectly.. but i cant raise the voltage in msi afterburner.. is there any other way to adjust or its already done in the bios ?

[I.nfraR.ed]

Have you enabled the voltage control in the settings?
Click on settings button on the bottom of AB, then in the General tab tick both checkboxes
- Unlock voltage control
- Unlock voltage monitoring

I haven't done any voltage adjustments to the P-states, but only increased the maximum limit to 1.2125V

If this is still working can i get my bios modded to unlock all voltages including the memory voltage. Thanks

I have an EVGA gts450 and was hoping to get fan speed unlocked.

Anyone? Also can you point me in the right direction to get my bios for you to mod?

[I.nfraR.ed]

Save it with gpuz - image.
Then zip it and attach it here, I will mod it when I get back from work.

Majjiks, guess it's too late, but will mod yours, too. Memory voltage can't be controlled via software on reference models (not sure about MSI custom models),
so I'm only left with Vgpu llimit and fan control.

I will do a short how-to, so everyone can do it - it's not a rocket science on this one and it's pretty safe.

PS: I have problems downloading Majjiks' zip file.
