I want a faster 6600gt.

[fps justin]

WOW. Thats real good. Although i doubt i'd change the voltage to 1.75v That sounds bad for the card. LOL

[Tyreal]

It is pretty high but if you have the right cooling then you shouldn't have too many problems. videocard GPUs are tougher than CPU cores.

[fps justin]

How well would the card perform against other cards? for example, the 6800gt at stock.

[Tyreal]

it would certainly beat a 6800. It will be a close match up.

[fps justin]

ok. NOW i'm interested. Mabye i could get the electronics teacher to do it for me... Then i would buy some mem sinks and i'll have either a dead card or a 1337 card.

It could save me a good year or 2 if it works out...

Check this out... It says if your not comfortable sodering you can use pencil mod. Does that mean i don't actaully have to do anything dangerous?

hold on to your pentyhose :) I'm putting together a little guide about using nibitor - a nice little bios tweaking utility. there is voltmode and more. 15 more minutes.

[sbohdan]

all right . here is a little guide how to tweak your bios with a smart little tool called nibitor2.8a.

first download nibitor from the mvktech website: http://www.mvktech.net/component/opt...cat,92/page,3/

after extracting nibitor open it. you can extract your own VGA's bios by clicking tools---read bos---select device
then click again tools---read bios--read into nibitor


you will see this. this is your own cards bios ready to be tweaked :) :


here you can set the GPU and memory default speeds (these will be your cards default speeds after reflashing with the modified bios. ex.: if in this case the default was originally 500Mhz for the GPU and 500 (1000Mhz effective) for the mem. and you were able to get 580MHz on THe GPU without artifacts, than you can set the default speed to 550Mhz for inbstance (to be on safe side) or if you are really sure there is no artifacting and your GPU can take the 580Mhz even in extensive 3D gaming than you can set it to 580Mhz (in this case) and the memory accordingly. after the reflash of your own tweaked bios, there will be no need to OC the card with other utilities because it will be oC'd at default :) just remember: make sure your card and the cooling can take the higher speeds (give them an extensive torture test with 3dmark and monitor the temps. also remember: only raise the 3D speeds, since 2D has no influence on gaming. I actually have a card (6800LE), that i turned to a GT where I lowered the 2D GPU and mem. speeds to save power when not gaming.
you could also aquire the right timingset for your card's memory, which will be usefull when adjusting timingsets on the timingsets tab. just click bootup clocks--autoselect and it will find you the best recommended timingset. you can choose that one on the timingset tab or just test other timingsets and see if there is performance improvement from doing so. for now just leave the timingsets alone-those could be experienced with after tweaking and successfully reflashing , testing the new tweaked bios.

next tab is the voltages. here, you can eighter choose a 0.1 voltage raise in 3D or if you don't have a higher option, then click tools--voltage tble editor and there add a higher (0.1) voltage increase:




now going back to the voltage tab, you have the higher voltage option now:


the next tab would be the timings, where you can choose the new recommended timingset for your card, but as I said, I would leave this for a second part of the tweak, after all else works fine, so that you know, that any problems are caused by changing the timingset and not the voltage for example. so leave it for now:



the next tab which is more for fun and looks than performance is the boot settings tab. here you can change what , where (ex. middle), what color and how long it appears - should be the text that appears the first at boot-up, when your video card is identified:



after you are finished with tweaking your bios, just save it under a new name (make sure it's short, because long names are altered in DOS and you might have a problem entering the bios's name when flashing)
so just click file--save bios and save the new bios.

about flashing the new bios: I allready had that written down another guide but basically you need to download a little utility called nvflash: http://www.mvktech.net/component/opt...58ad2f9318800/

and put it along with the modified bios on a bootable disc (to make a boot disc: open explorer---right click A drive---format---check the "make a bootable disc")

next, restart the computer, go to bios, change the boot sequence to floppy first and after saving the setting restart with the bootfloppy in the drive. it will start booting in. once it stops, you see this:

A\:

write: dir (A\:dir) and hit enter
you will see the contents of the boot floppy you made. make sure you see the modified bios and the name (if the name was too long it could look different). If all OK, then first save your original bios by writing: A\:nvflash --save

once you have the original bios on the floppy, you can flash the modified bios on your card by typing: A\:nvflash -4 -5 -6 newbios.rom (where in the place of the "new bios" you put the name under which the modified bios is saved. hit enter. when asked click "y" to allow the flashing. flashing starts and it will say it's done, just turn off your computer (make sure the flashing process is over! don't ever turn off the computer during flashing!
turn it back on--your new bios should be on your card. test it extensively with 3dmark to see if everything is fine. you are done. for those of you who are more adventurous, you can now test different timing sets to find the best one for your memory.
that's it folks :P

Wow, helluva post sbohdan!!!!! :shock:
Awesome work as usual :thup:

[Tyreal]

Are you planning on developping your guide more and maybe getting it on the actual site? or possibly a sticky for the nvidia section?
