8800GT bios for better overclocking! *test*

[r4st4m4n]

I just noticed something i thought was kinda odd. Some peoples 'Exact Mode - Extra Voltage' is blank, mine is blank as well. but if you select hex view, you'll see the actual value.

Example, my EVGA 8800GT SC (650MHz), has a hex value of 0x82. which is 130 in decimal... in other words it's set to 1.3V. actual voltage is probably not that... but it is still kinda odd that it's set to that. so if it is set to an un-supported voltage, like 1.3, does it default down to 1.1V or default to something else? i guess checking with a volt meter would tell us.

In the pic below, is my cards default settings, read from the bios (bottom).. and EVGA SSC (top), read from a dump... that i was playing with to compare differences. it's default was 1.05V or 0x69, i was just playing around with it to see how the adjustments change the hex value.

kinda odd, huh?

According to Mavke (I think is the developer of Nibitor), the only things that the card recognize is the VID number between 1 to 4. 4 = 1.1V, 3 = 1.05V, ...
When you see in nibitor 1.1V, this only a label that nibitor make correspond to a VID but this label is only internal to nibitor and it's not taken from the bios.

So it is not possible to go higher than 1.1V since the card doesn't recognize other VID. This has been confirmed by Jason who tried to set the VID to 5, but as result the card reverted to a lower value, probably 1.05V.
Some people also tried to change the label in nibitor but as explained later by mavke, it didn't do nothing. It was also confirmed by the multimeter.

So I'm not sure what hex value you are reading but it is not the Vcore value. All the explanation above can be found in the previous posts. Check for Mavke's one.

And as you can see in the image below, the part of the bios you are reading doesn't seem to be a part of the voltage table:
