BIOS Flashing a GPU

[AMD Lover]

So i have a MSI 660ti Power Edition and the voltage control is locked under 1.17v. I would like to raise this so my question is would fashing the card to a different (Older or Newer BIOS unlock this) also if that wouldn't would flashing the card to a different manufacturer who left their card unlocked work? (If so you you happen to remember what brand and BIOS version)?

the power limit is made by nvidia as far a I know... But honestly i am not sure weather you want to overvolt a 660ti. I promise you the performance you get out of it is not worth the work of flashing the bios, which can be a pain in the rear and risking your card, because i dont think it has dual bios. If your bios gest screwed, while flashing the card is prbably gone because there are no removable bios chips on gpus... if you really want to do it though you should be able to google an unlocked bios for the 660ti

I wouldnt say the performance gain from overvolting a 660 ti is worth the trouble and risk of flashing the card's bios.

I flashed the BIOS to an updated official version yesterday with no problems but the voltage is still locked.

This guy @Jumper has given you the right tools and website for doing what you want to do. I also used similar tools and got my voltage to 1.212v as the maximum now, i can also do 1280Mhz on the GPU boost and 7002 Mhz on the memory stably.

I used kepler bios tweaker and Nvflash in DOS to boost stock clocks and boost clocks/Fan percentage on my zotac 770. Unless you physically modify the card I don't think you can go over 1.212v as keplers (idk which ones) have a resistor but i'm not sure as sometimes my gigabyte 770 will say 1.22v

 

 

P.S. It's also pretty safe to flash a GPU atleast in DOS so aslong as you follow a guide and try to have the same firmware name and dont force flash it you should be fine youll have to reinstall drivers sometimes after flashing just incase. also make sure you have a backup GPU incase you brick it so you can reflash it and unbrickify it.

I found this a couple hours before you posted, running at 1.212v I'm at a CC of 1305Mhz but I can't get the memory above 3000Mhz so idk what's going on!

Edit: do I need to bump up memory voltage

Either the memory voltage or power target or maybe this is the limit of your GPU. In my case 1306MHz is a bit too hot for me so i reduced the boost clock.

[Cwazywazy]

I tried to mod the BIOS of my card (650ti) to raise the voltage limit which is a measly 1.162v. All I managed to do is lock the standard voltage to 1.162v. (For some reason it refuses to go higher even though it stays cool just fine.)

Yeah I almost need to add a liquid cooler to mine at that clock, I have to keep the GPU fans at 70% to keep it from throttling

Whats your Memory Voltage and memory speed at in After Burner because im at a Memory Voltage of +40mV off stock and a Memory clock of +650 off stock and Afterburner says im at like 3570Mhz (Mem OC) or something like that and GPUZ only says 1557Mhz..... Im confused all the way around, also ive dropped my Core Clock to 1280Mhz

GDDR5 works as quad data rate. Gpuz is showing base clock, and afterburner ddr clock. Your effective clock is 3570x2 mhz or 1557x4 mhz

I use GPU Tweak, not GPU-Z and there is no specific memory voltage only minimum, what it is using at any give time and maximum GPU voltage. At stock BIOS and settings the GPU voltage it is at offset 0 which equals 0.987v minimum and a maximum or 1.180v or something like that and with my stable OC and custom BIOS i have an offset of +63 which has the minimum voltage at 0.987v and the maximum of 1.212v.

 

I have two OC settings for the custom BIOS, one with the same GPU voltage listed above but one has the memory clock with an offset of +440 which is 6448Mhz and one with the memory clock with an offset of +1000 which is 7008Mhz. Both are stable.

 

My fan speed is 70% and i have found a youtube video that showed how to quiet the fans on the GPU and i tried it and it is much quieter, i can live with it. Before it was loud but now with any coil whine just a hum.

 

When i play CoD Ghosts i get a temperature of 61C for the highest with ultra settings in game and on the Nvidia's control panel and i use my GPU for Phys-X and not my CPU.

 

@LukaP is correct so just do the calculation for your figures, also, this is why i use only one program to monitor my figures .

Can i get that YouTube video?

[Leonard]

Can i get that YouTube video?

It starts out as just another lunatic with an internet connection and a recording device but this mess actually worked for me. I did not use any glue, i just cut some of my girlfriends makeup cotton pads to the shape of the plastic part that my GPU's fan rests on, used the screws to hold the fans back in place with the cotton behind the fan and bam, noise cut in half.
