8800GT bios for better overclocking! *test*

[ziddey]

it's probably already been mentioned, but i'm such a lazy ass. at the same clocks, how much do you lose by loosening timings? i imagine that the added clocks from loosening timings is still better than the max possible at the tighter timings?

[smsmasters]

I didn't notice any difference. I'm just glad my RAM is much more stable now at higher frequencies.

[nuttah]

There was one time when overclocking had a meaning :P

[smsmasters]

I did gain 10fps in the CSS video stress test by overclocking the RAM from 950 to 1053.

Hey for all you people that wanted to know my stock volt. (please tell me what it is)



On this i get 771/1935/1015 Completly stable.

thanks

Click on the 'Exact Mode' tab and then show us the screenshot.

[A_Tiny_Chipmunk]

umm theres nothing under it. all feilds are blank.

[alexio]

It's 1.1v stock

[A_Tiny_Chipmunk]

lol ok, thanks. That explains the high clocks and why it was a bit hot on the stock cooler. So is it possible to get 1.15? i think i was reading this thred and someone got 1.15 or 1.2? i would much rather no solder something to my card.

The XFX Alpha Dog is reference design so that's not possible. Maybe some cards in the future will be able to have higher vcore than 1.1v. I think one Gigabyte card (don't know if it's released yet) may have the hardware onboard for higher than 1.1v. It comes with software to change vGPU, so who knows...?

I updated your memory timings on my XFX Alpha Dog edition bios and was pleasantly surprised with a bit more of overclocking. Earlier my max. was 736/1836/1022 after the bios mod my best overclock is 756/1900/1050 and it did bring improvements in my 3dMark scores though have not tried it in any of the games.

i have teh same card as you. but yet they say i already have 1.1v inthe bios?

ummmm....i dont know but in my exact mode i had Extra set to 1.05Volts and while modifying the bios i changed it to 1.1V, i think that explains the extra clocks on core and shaders????

I think a lot of the Alpha Dog cards are coming w/ 1.1v stock, but you could always try changing the "Extra" block under the 'Exact Mode' tab to 1.1v. Some cards (mine included) also had all fields blank, but changing it to 1.1v helped me a lot.

Just make sure to save a copy of your original BIOS in case you want to go back to stock later.

There is currently no way to get more than 1.1v through a BIOS modification on reference design boards. Believe me, I've tried!

ok. is there anyway of flashing from windows? or will there ever be? Also if i do flash from dos, i will have to use a flash drive (does this b4 on my xbox 360) but cant remember how to make a bootable flash drive. Then again i dont have a pci video card incase i screw up and i also dont have onboard..

/cry

I used this to make my USB stick bootable and used it to flash my 8800GT BIOS.

Here a tutorial to make a bootable DOS USB stick: http://www.bay-wolf.com/usbmemstick.htm

There is a way to do a "blind" restore from the thumb drive. Read the NVIDIA flash guides here: http://www.mvktech.net/content/category/4/67/37/

Test it before since the options they give to do a blind restore didn't work for me. I think it says to use "a:nvlfash -4 -5 -6 -a -y file.rom [Enter]" while I think I had to remove the option "-4" for me to make it work (I'm not 100% sure about that, test the restore by yourself with the original biod before to flash with another one).

[A_Tiny_Chipmunk]

gah, i cant even find my flash drive now. So to get this right. (when i do find it) i just load my bios, save it (backup) then change it with nibitor then save that and flash the one i changed to the card. Is the extra the only thing i change? and am i changing it to 1.1? thanks.

Anyone have a modified or stock BFG 8800GT OC2 (preferably) bios?

My HDD fried and I never had a second backup. The updater doesn't work for me (and i'm too lazy to change the hex bits so it updates).

Thanks

Yes & yes

Mvktech has a database of bioses. Maybe you'll find yours: http://www.mvktech.net/

I heard that there are new bioses out from evga to speed up the fan at lower temperatures.

Is there any way to copy those settings and apply it to the older bioses without this feature?

Latest version of Nibitor (3.7 IIRC) allow you to do that

[counsol]

what settings are used for the new bioses for the temperature?

[r4st4m4n]

After opening your bios in Nibitor, go to the tab "temperatures", then click on Fanspeed IC.
There, if you select "automatic Speed, you can play with Tmin, TRange slope and min duty cycle to have the fan speed increasing according to the temperature of the core. The mechanism / thresholds are well described in nibitor itself.

IIRC for my 8800GT, I have set Tmin to 60*C, TRange slope to 20*C and min duty cycle to 30%.
As result the fan speed will slowly increase when the core reaches about 64-65 degrees. The temperatures will stabilize at about 75 - 80*C depending of the load, with the fan spinning at about 60-65% at this temps, although in nibitor it says that at 80*C the fan should spin at 100%.
