560ti bios flash?

post #1 of 11
Thread Starter 
Okay well ive been reading around and ive seen a lot of people flashing different bios onto their 560ti's... just courious what the point of that is, its not like the 6950 that you can flash to unlock shaders to make it a 6970 is it?

EVGA 560ti 2gb model 1000Mhz core clock 2000mhz shader, 2175mhz memory at 1085mV 99% load temps 58c

I want to know whats up with bios flashes myself... Wouldn't it be legit if all 560ti were 448 cores just locked and now they decided to unlock them biggrin.gif

People flash different bios's for many reasons

- To allow for higher core voltage
- To make your card factory overclocked
- To change the fan profile

Pretty much all related around overclocking

The 448 core 560 ti and the original 560 ti's have completely different architectures so it is not possible to unlock to a 448 core.

The reason that it is called a 448 core is because it has just that, the 560 ti that I am using utilizes 384 processing cores. Those AMD cards that flash were basically the same card with a some features locked to create new sku's. Nowadays it is difficult to find these cards that will flash.

I think the reason people flash 560 ti bios is to set their cards at a specific setting. For example, one's card boots at stock settings of 822 core/ 1800 shaders / 2004 memory clock. If he/she doesnt want to use afterburner or 3rd party software to change settings everytime, there is the option of flashing your own settings using nibitor. Another reason would be to mod voltages etc.

Cannot be done.
Original 560Ti is GF114, new 448 Core version in GF110.
Two different architectures.
The 448 core has 40 Raster operators compared to the originals 32.
The 448 core has a 320-bit wide memory bus, while the original was only 256-bit.
The 448 core is essentially a GTX 570 with a shader cluster laser cut (GTX570 = 15 Clusters, GTX 560TI 448 = 14 Clusters), with GTX 570 speeds.

That is why.

I have flashed many a card.

Pretty much this, I know my Twin Frozr II 560 Ti's Bios is allowed for higher core voltage and is factory overclocked slightly, I'm sure other 560 ti's have them locked and stuck at stock.

hmm im using the evga version and everything is unlocked to change it never occurred to me that a gpu would ship with settings locked, and to flashing your own settings most overclocking programs have a apply settings at windows startup <<< seems like a better option to me.
