Whoa, so I can just get a BIOS for my eVGA 6600GT AGP That will raise the core clock instead of having to do a volt mod? I'd much rather do that. I enabled temp monitoring through hexedit and changing the cards, BIOS but I don't know how to do anything beyond that.
Hmmm see this mod.Quote:

Yes vr-zone isn't loading; try later.Quote:

Damn nice dude. Hope my card will want to do that good with water cooling without any mods. MAZE4 GPU?Quote:

thanks devilek will use those riva tuner. currently i'm still running those stock bios with temp monitoring. need better cooling for it. have to wait for better cooling since artic cooling wont made any cooler for 6600GT agp vers. maybe going WC like u. what water blobk did u use?
Guys! I used Nibitor 2.0a from www.mvktech.net to mod frequencies...but VGPU is set to 1,4...as default. Nibitor doesn't allow to increase it but it can show us the HexCode.....so....it's also possible to increase the VGPU manually because....
130 (1,3V) = 82 (hex)
140 (1,4V) = 8C (hex)
150 (1,5V) = 96 (hex)
If we set it to 96 in HEX we should have 1,5V.....or not?!?!? is there an hardware limit? has someone tried it?
Hi :)
My GPU is cooled by Abandon :D
Exactly this

@Nubius do You see this mod on vr-zone ?
Sory 4 my english
im also interested in this, my card is the same, does anyone have an answer?Quote:

It looks like that solder spot is the back end of that resistor they show in Vr-Zone.....but now I'm paranoid lol, don't know which one to trust. I think I could much more easily solder a leg to that one on the back, and then the other variable resistor leg to a random ground point, than trying to solder each leg to each end of those tiny resistors on the front.
I have no soldering skills lol, and I'd have to go out and buy a fine tipped soldering iron. As far as pencil mod goes....hmm I might give that a shot, but first I need to see how far I can go when I get water and then decide if attempting to fry my card is necessary :p:
I 3rd that interest. I'm way interested in knowing if I can simply change voltage through the BIOS instead of having to try a volt mod.Quote:

EDIT: Got nibitor....glancing around through the BIOS.....terrified to actually try anything though lol, I don't have a PCI card on hand if things go wrong...plus I don't have but stock cooling so currently I don't need to be raising the voltage. Also, how do you know that 96 is the correct hex for making the voltage to 1.5? I don't say that in a way that I'm doubting, you I'm just curious for informational sakes because I have no clue and am interested before I go changing stuff.
just an FYI, doing anything in nibitor wont affect your card unless you actually flash it, which requires a disk :)
lol yeah I know that, I was messing around with the options and whatnot, just to see what part of the BIOS it changed. The only BIOS 'modification' I've done was using Hextreme and enabling the temp monitor using info from nvidia forums:Quote:

But that had people who had done it successfully and said it worked great. Raising the voltage in this case is a guess right now :p: but I'm definitely interested in it.
same here
Aright I found this program called VGABIOS.EXE that's supposed to test a BIOS for you so you don't have to flash the card with it and possibly screw something up.
Put it on the floppy with the modded BIOS with 96 hex for supposed 1.5v
(BTW: Program can be found here - http://whitebunny.demon.nl/hardware/chipset_nvidia.html)
And I typed in the parameters it said to on that page I just linked.
BIOSVOLTS.ROM was the name of my BIOS
VGABIOS -FBIOSVOLTS.ROM
And it runs I guess, it doesn't give any kind of confirmation or error or anything like that, so I don't know if it's safe to flash it with that newly modified BIOS with the 96 hex or not lol. Someone else want to give it a go and see if they find anything else more than myself?
Well...it's 96 beacause 150(1,5V) in hex is 96... :) ...if you open the Windows Calculator and set it to "scientific" you can convert a decimal number to a hexadecimal one...Quote:

You ever used that VGABIOS thing I talked about in that previous post? I'm guessing i did it right, I typed in the parameters explained on the website, but it didn't give any error or confirmation, so I assume you go by if your screen is garbled or just disappears?
I'm afraid to go through with the flash though lol. Plus I only have stock cooling right now, and I don't care to try and poke around with the multimeter while it's in the case :p:
I want another guinea pig to try it and let me know of it's success hehe
Aright, was feeling a bit curious...perhaps some may say crazy.....but I went ahead and tried to flash with the BIOS I saved using that nibitor program. I changed the voltage area in the hexview from 8C to 96 and then saved the file. Integrity was green everything looking good.
Used that VGABIOS.EXE one more time for the hell of it. Same thing, no errors, no confirmation or anything.
So then I proceeded to flash
nvflash -5 -6 BIOSVOLTS.ROM
Then it says I/O error: Cannot read BIOS
Sooooo yeah, don't know :stick:
so...doesn't it flash the bios?
the vgabios.exe doesn't flash. It's supposed to just show you that it works, so like I said I guess if your screen goes garbled, you pop out the floppy and reboot and then boom you don't have to worry about a screwed up card.
But it says it can't read the BIOS file so nvflash didn't flash it =/
So...when you tried with VGABIOS there was nothing on the screen?
mmm...there is another thing to try....
in nibitor, in the Voltage tab there is VID MODE tab.
so in the bios, any voltage has a VID....so 1=1.2V and 3=1.4V.....
so we must mod the hex code for the voltage to 96 and the VID number to 4........i think
now i try with VGABIOS....
Well it just said likeQuote:
So...when you tried with VGABIOS there was nothing on the screen?
VGA BIOS 1.10 Copyright
Usage VGA BIOS -fbios.rom -tM
and a little other tidbits of info, but nothing like 'BIOS TESTING CONFIRMED'
or 'ERROR BAD BIOS'
EDIT:Hmm I didn't do the VID mode tab, I just clicked the voltage tab, then brought in hex view and changed it from 8X to 96...I just did the same in Hextreme, but I haven't tried flashing again, Honestly I'm scared lol. I'm poor, I can't afford FX-55's and phase change, and a couple 6800Ultras and crap. If this dies I'm screwed, and I have no PCI card to use for backup precautions.Quote:

I suppose I could 'blind flash' like the guy says...with nothing on the screen, but yeah I'm paranoid
My VID info is showing 0 = 1.3v and 3 = 1.4 anything in between says ??
Like I said I modded the hex to 96, but when I tried flashing nvflash gave me that I/O error, could not read BIOS
VGABIOS says you that you are typing wrong...if your bios is called "bios.rom" you must type:
VGABIOS -Fbios.rom
now I'm trying....i will inform you about it...
