6600gt Bios

[Verdict]

if someone have/found bios for that card, post link here :)

i have 5.43.02.36.52 bios now and im finding newer or better...

I dont know whats the normal voltage on that card, but clocks can be default
I rise those with power strip... you can change voltages???

What is safe on stock cooling?

[[XC] moddolicous]

Verdict, what are the stock speeds of the 6600GT. I am getting a weird reading from hex workshop. I think 1.4 is safe on stock cooling, but I'm not sure

What card do you have?
Check www.mvktech.net for more BIOS's :-)
And mail yours to mavke@mvktech.net as he might have more BIOS's!

i have PNY 6600GT, i take rev2 bios from your site for my card but it says " image and card ID not match "

can i force it, i have AGP card, is that for it?

[Mavke]

Yeps it for the AGP... And you are not using the correct nvflash parameters I think.
So you better try : And use nvflash v4.42...
nvflash -r (removes any protection)
nvflash -b ORIGBIOS.ROM (saves original bios)
nvflash -u -p -f BIOSNAME.ROM (flash new bios file)

However because of DOS filename restriction, "ORIGBIOS.ROM" and "BIOSNAME.ROM" must have max of 8 char's in first part of filename and max of 3 char's in extender part, otherwise DOS will not recognise command.

its not workin :confused:

i tried 4.42 and 4.46, those says: nvidia display adapters not found...
then i test 5.06, 5.10 and 5.12
and not working, i use command : nvflash -6 -5 bios.rom "with 5.?? versions"

[Mavke]

What command did you exactly use?
And did you boot up from a DOS bootable diskette?
(And also check my site we have some specialists to help you get the flash working...)

[ISS]

Current version of nvflash is screwed for 6600GT. Maybe the programmer is just plain dumb or remove the override function on purpose. You can no longer over ride current BIOS with another vendor's BIOS. Even if you use -5 and -6 which are overridetype and overridesub, the software still checks for a match and it will tell you board ID mismatch.

I just wonder why can nvflash function the same as ATI's flashrom utility, just use a single -f to force flash the card regardless of ID mismatch? *sigh*

just info, stock clocks r mostly 500/900 or 1000 (set it to 1000Mhz coze all memory is 2ns or 1.6ns) & stoc k voltage is 1.4V, so if ya can set it set it to 1.5 or 1.6V pls :D

Verdict, I finally got around to modding your bios. Here it is. Its stock clock speeds with 1.4V for both 3d and 2d speeds. They were originally set to 1.3. It should match.

On Mavke's site, that is a Rev. A01 BIOS (for the PNY Verto 6600 GT AGP). I uploaded the A02 BIOS 5.43.02.39.51 to his site on Dec. 30 for the same card, but Rev. A02 as evidenced by these pictures showing revision at top left when looking at the fan side. Verdict might want to look at the Rev on his PCB to see what his Rev. is.

Is there any chance you can Mod this newer BIOS for me as well?

you use this bios?

i can flash your modded bios. id mismatch error or something :confused:

[[XC] moddolicous]

wait, you can flash my modded bios or not?

edit

Download savebios, and get a copy of your current bios. I'll mod it then give it back to you.

[MaRtIe]

what can you do to them? i have a 6600GT... maybe thinking of moded bios. dunno yet

You could raise the voltages so you can acheive higher OC's, but only on the core. You could make your 3d clocks and your 2d clocks the same to get rid of the cold throttling.

If you use the one I originally modded for verdict, that one has 1.4v, and clocks are 500/900. Thats should be what you are looking for.

[MaRtIe]

would you be willing to add more voltage to my XfX6600GT?

[[XC] moddolicous]

how much? 1.5? I cant go higher in the bios than 1.5

[Verdict]

sry my bad english
i can not flash that because it says something about ID :(

[[XC] moddolicous]

can you use savebios? here it is. Unzip it and double click. It should give you a copy of your bios on your vid card.

[Verdict]

ok here...

http://www.oc-rapid.com/6600GT/VIDBIOS.BIN

[[XC] moddolicous]

I dont know why, but I cant understand what the hexworkshop is saying. I cant find where to make the changes. Most of the other 6600GT bioses are easier to find them. It might take me a little time.

[MaRtIe]

1.5V, i dunno if its safe on the stock cooling, 45C idle?

[[XC] moddolicous]

I didnt check, the highest it says the card can do is 1.4v through the bios. that means you'll need a hard mod to go above. Here is the bios. Clocks are 500/1000. Volts are 1.4. It should be OK at 1.4 on stock cooling. Just for your info, it was originally 1.3V.

whos is that bios?

[[XC] moddolicous]

whos is that bios?

I got that bios off of mkvtech.net. It was under XFX 6600GT bios. I downloaded it and modded it for you. It should work.

[MaRtIe]

thanks :toast:

[[XC] moddolicous]

report back if you had good results

[MaRtIe]

will do, just pluging my floppy in now and gathering the flash tools

[MaRtIe]

floppy drive doesnt work, (anceint) any other way a video bios can be flashed?

[[XC] moddolicous]

you can try doing through windows, but I'm not sure it will work..
1 click run and type cmd
2 put the utility and the bios and anything else you need in the documents and settings folder
3 use the same commands and it should flash. Not sure
Good luck

[MaRtIe]

cant get it to work,

how about a boot cd?

[[XC] moddolicous]

that will work.. Forgot about that.

[MaRtIe]

so all id do is put the files that would be on the floppy on the cd instead?

[[XC] moddolicous]

yea, but you have to be able to make it bootable. I'm not sure how to though

[Mavke]

If you look for BIOS's then check mvktech.net (http://www.mvktech.net)... And also try to upload or to mail me your Original BIOS.

If you want to mod a BIOS yourself then use NiBiTor (it is available on mvktech.net (http://www.mvktech.net)).

Is the XFX 6600GT bios on that site for the AGP version?

If not, anyone know of a modded bios that will work with the AGP version of XFX 6600GT?

Edit: Nevermind, i found out via the forums. It might be a good idea to specify at the download pages though.

Does this XFX bios on there have upped vgpu?

[Mavke]

Does this XFX bios on there have upped vgpu?
All BIOS's on my site are the Original Versions. If you need to up the voltage then use NiBiTor (also on our site, and developed by someone I know and beta tested by myself).
And also I would like to get as much 6600/6600GT BIOS's so if some do have such a card please send me the BIOS!
mavke@mvktech.net (mailto:mavke@mvktech.net)

[MaRtIe]

i have my original XFX 6600GT AGP8 bios. ile mail it you :)

[Mavke]

Thanks! I look forward to receiving it... :-)

[MaRtIe]

ok i attached it in an email on msn. i sent it to this mavke@mvktech.net if thats ok?

tell me if you get it

[Mavke]

I got it :-)

[MaRtIe]

lemmi know if u got any probs :) enjoy

[q149]

Anyone know any 6600GT AGP bioses that will allow for higher Vgpu with NiBiTor? The XFX one will only go to 1.4v which is the default anyway

[[XC] moddolicous]

I didnt know they make AGP 6600gt. What make is your card?

They make alot of them now. Mine is an XFX

[i found nemo]

could you edit my computer bios? http://h18007.www1.hp.com/support/files/Deskpro/us/download/16560.html

i'd like all multipliers availible...and all supported v.core and all fsb's avalible

tyvm if you do this it's just a pain in the butt cuz i can't oc my comp worth the...well you know if it's not able to be cracked, then oh well i guess

[MaRtIe]

it's not as simple as just unlocking multipliers. intel = locked unless its an ES. i dought there is any vcore/FSB options anyway.

[i found nemo]

oh, well could you just give me ram timings, cuz the bios won't let me...i think it's locked..dunno if it's even availble...could you check for me anyways...? plz??? give you a nickle lol...plz...

samsung chips and not remember what is written on the memory chips

[BiKEKiNG]

samsung 443

[[XC] moddolicous]

I think what mavke means, and correct me if I'm wrong, is that he needs a copy of your bios because companies put new bioses on their cards, and if he gets it, he would be able to put it on his website. All you would have to use is savebios. Google it, and you should find it.

Of cource a modded bios for my Gainward 6600GT PCI-EX with 1.4v and can run SLI mode :p:

[Mavke]

Does it run now SLI? With the Original BIOS?

[stardust]

Do you think altering bioses will change the pci-e frequency tolerance of the video card?

I have a gigabyte 6600GT PCI-E and the official release F2 bios allows much higher pci-e frequency than F1 bios, but still not enough.

Anyone have any ideas? Do you think the BFG bios will work with my card?

[xs64]

Does it run now SLI? With the Original BIOS?
Yes , the original that i attached can run SLI mode

[Veedo]

heres the bios for the Asus EN 6600GT > Asus EN6600GT (http://webpages.charter.net/davelaux/ASUS.zip)

another to add to your collection :) . if you could mod it to 1.4 volts that would be cool too. not planning on doing it until i get a better cooler, but i would like to have it for the future. has anyone noticed better overclocking with the extra voltage? did the temps increase much?

[Mavke]

Thanks Veedo! Great stuff.
Well NiBiTor is not yet fully supporting the 6600/6600GT series but in the upcoming new version it will be. ;)

played around with the card. standard gpu/mem = 500/500 (1000 DDR)
max mem was 1250 DDR / gpu 510. think gpu core is 1.3v

I'll add a little to the endless requests :P

Inno3d 6600GT 1.6ns more voltage...on core if you can do mem as well...all the better...Don't know what the default voltage is unfortunately (one day i will get a multimeter Do i need to post the bios already on card? I can post it easily cause i got it on floppy,

[Mavke]

Well that is not possible the memory voltage is not controlled within the BIOS really and the GPU voltage table is coming from NVIDIA and you can't modify it. But if you can provide your BIOS we can take a look... So please provide your BIOS... Is it a PCIe?

[DeltZ]

tis AGP:) here it is anyway...

Is there actually any more to this bios modding than using Nibitor program? cause i had a look at my bios through the program and it seemed already set on 1.4 volts (so i assume it was stock) but it doesn't go anyhigher...even with extended voltages...does this mean mine can't be changed? :(

to make a copy of your bios just use savebios (not sure where to get it. check mvktech.net). I meant stock clocks (ie 500/500).

[saaya]

stock clocks are 550/1125

cant you use the leadtek 6600gt extreme bios from the database?
im sure its the same bios i have on my card now...

[[XC] moddolicous]

OK, here is your bios. It has 1.4v, and stock clocks (didnt know if you wanted me to up them any). As per your earlier post, If anything goes wrong, there is definetly at least 1 person that went through something like that here that could help you. Nothing wrong should happen though.

I dont know why it would be .bin, cause the one I got off mkvtech.net was .rom. Here is your bios, but it is a rom bios, so you could try flashing it with this. Also, you could download hexeditor and change it to .bin, or I'll do it if you want. Here it is as .bin and .rom

yeah but still 1.4v :(

Okay! That is fine and then I can look at it.

[rzonealley]

Mavke here's the bios for Chaintech 6600GT agp. if possible can u do two vers of it:
1. original bios + temp monitoring
2. modded with some tweaks + temp monitoring

so far the card work fine interms of performance but still cant break the 10k barrier... with my system only can reach 9.9k

[Mavke]

Okay I will check and get back to you... But don't get impatience, cause I am leaving to Stockholm in about an hour and I will only be back on Friday (yeah for work, and this modding and stuff I do next to working)...

But just try NiBiTor v2.0a and you can make the above changes yourself via that Tool. :)

Hi all...I have a Prolink 6600Gt 128Mb AGP...I have overclocked it by modding BIOS... so now I stay at 545/1200.....Very low result for the CORE!...at 580Mhz card freezes...at 570 works well but there are some green artifacts...at 560 Mhz no problem but memory frequence stops at 1050Mhz beacause creates artifacts...with 545 Mhz Core Speed, memory at 1200mhz has no artifact. The Core has by default 1,4V...is it possible to increase it by the bios? I have attached my frequency modded bios...can someone voltmod it? Thanks to all!

[rzonealley]

Hardware limit. when u oc the driver will detect the limitation of the card provided by bios right? in example max for my card clock is 590/1260. when i push it more on core or mem and test setting it will revert back to the previous clock. i guess its becoz of limitation thingy isnt it? i'm thinking bout removing the limitation and see if my card can bench at 600/12xx or hopefully 600/1300.
i dont know the things such a limitation is exist or not. but if theres limitation i'm willing to remove it thats what xtreame is all about isn't it. hehe

And you are lucky! My card stop to go with driver overclock at 580/1100....now I stay at 545/1200 thanks to Bios Update....

But haven't you any visual artifact at 590Mhz?? In 3dMark03(Battle of Proxicon) I see green triangles on robots..

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 (http://www.vr-zone.com/?i=1912&s=1) mod.

[Nubius]

Hmm page isn't loading as of right now =/ I'll try it later though, guess it's bogged down or soemthin right now. I see you have your 6600GT quite nicely OC'd.....is that with a hardware voltage mod?

Yes vr-zone isn't loading; try later.
My card is water cooling, stock voltage and no vmod.

[Nubius]

My card is water cooling, stock voltage and no vmod. Damn nice dude. Hope my card will want to do that good with water cooling without any mods. MAZE4 GPU?

[rzonealley]

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?

[gianvito]

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?

[DEVIL K-ce]

Hi :)

My GPU is cooled by Abandon :D

Exactly this

im also interested in this, my card is the same, does anyone have an answer?

[Nubius]

@Nubius do You see this mod on vr-zone ? Yes I did thankya :D Got the site to load last night actually. Probably the best and cleanest voltage mod instructions I've seen for that card. I was also sent this photo by a guy on these forums:

http://www.xtremesystems.org/forums/attachment.php?attachmentid=26865

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:

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.

[Plague]

just an FYI, doing anything in nibitor wont affect your card unless you actually flash it, which requires a disk :)

[Nubius]

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:

http://forums.nvidia.com/index.php?showtopic=1945&st=0

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.

[Plague]

same here

[Nubius]

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...

but i haven't tried it...

[Nubius]

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... lol crazy! I actually did try it, opened up windows editor and whatnot and yeah you're right. Typed in 150 hit hex and boom up came 96.

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

[Nubius]

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:

[gianvito]

so...doesn't it flash the bios?

[Nubius]

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 =/

[gianvito]

So...when you tried with VGABIOS there was nothing on the screen?

[gianvito]

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....

[Nubius]

So...when you tried with VGABIOS there was nothing on the screen? Well it just said like

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:
mmm...there is another thing to try....

now i try with VGABIOS.... 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.

I suppose I could 'blind flash' like the guy says...with nothing on the screen, but yeah I'm paranoid

[Nubius]

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

[gianvito]

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...

[gianvito]

well...I tried with VGABIOS...it says that Bios is loaded succesfully.....now i will procede to flash..

[Plague]

ya know what, why dont you just let me flash it cause i have a spare pci card in case anything screws up. ill let ya know how it turned out within half an hour

[mare87]

Can someone please change my gpu voltage to 1.4v and 1.5v ? I tried NiBiTor 2.0a and it doesn`t show the voltages. Card is a Leadtek 6600 GT AGP normal edition :). Here (http://users.volja.net/marko87/leadtek_stock.BIN) is the original bios.

now I'm trying....i will inform you about it... That's what I did type dude. My BIOS file was named BIOSVOLTS.ROM and I typed

VGABIOS -FBIOSVOLTS.ROM

I never got any message like 'Bios Loaded Successfully' though.


ya know what, why dont you just let me flash it cause i have a spare pci card in case anything screws up. ill let ya know how it turned out within half an hour

Aright I've attached the BIOS file I modded. Using the hex I changed it from 8C to 96, and the temp trick is also enabled, but I had that done previously so that was already within the code.

EDIT: Gianvito, did you try flashing with the voltage hex changed? Or did you Plaque?

[Nubius]

Aright, my file name is BIOSVOLT2.ROM as you can see it's the one I attached above.

I just booted from the floppy and this is what I typed in

VGABIOS -Fbiosvolt2.rom

and it says the following

Copyright (C) 1997-99, Nvidia Corp. All rights reserved

Usage: VGABIOS -fROMFILE -tM
ROMFILE is VGA BIOS ROM
M is TV Mode (0-5)
A:\>

That's exactly what my screen looks like after I've typed in that command. So as you can see theres no error, no confirmation or nothing.

If I type in just VGABIOS without anything else it'll say VGA BIOS NOT FOUND! at the end.....sooo yeah I don't know if it's working or not

[mare87]

mmm...you must save your bios with NVFLASH...

you must type: nvflash --save leadtek.rom

and then upload that file


Thanks for the help. Now NiBiTor reads it ok, but my max gpu volts are 1.4v? And I think the gpu is at 1.4v at the moment. Here (http://users.volja.net/marko87/leadtek.ROM) you have the new, original bios. Please mod it for me :).

[Nubius]

Here ya go dude. I've attached your BIOS file and changed the hex which is supposed to make it 1.5v according to the posts above and throughout this thread. Of course make sure you can unflash if anything goes wrong and I've renamed it so that you can keep the original on the disk too, as a backup, but I changed that one and only option for you like you wanted, so let us know if you can get a higher core clock or if everything goes smoothly.

[Plague]

do you know if the mod has worked? anyone try ocing this? i wasnt able to flash it because of cpu problems

[Nubius]

Nope, I modded that guys leadtek BIOS for him, and he hasn't replied back with any results :(

lol I was hoping you'd wind up doing it

[mare87]

Sorry guys I was sleeping :D. The guinea pig is safe :). Before flashing I ran rthdribl for full load temps and they stopped at 64°c for the GPU. Then I flashed with Nvflash 5.13 with nvflash biosmod.rom command because nothing else works :rolleyes:. Then it flashed and the temps are the same. Neither did OC-ing improved :(. In NiBiTor under volt section it doesn`t show anything under 3D.

[Veedo]

poopy. could you test with a multimeter just to be sure?

[gianvito]

Mmm...I tried to flash and it flashed succesfully but I'm having problems with Coolbit and RivaTuner.....if someone can measure the Voltage directly on the card please do it...

[mare87]

Hm can someone provide a link for checkpoints ? Thanks.

[Nubius]

http://www.xtremesystems.org/forums/attachment.php?attachmentid=26865

Theres voltage spots :D

Nibitor won't show anything under 3D voltage because 1.5v is beyond what the list will show. Technically this should mean your card is infact running at 1.5v unless like someone though earlier, theres a hardware limitation and without actually doing a volt mod the BIOS simply won't let it run at 1.5v

So two of you have flashed your cards with the 1.5v BIOS and it worked eh? Might have to give it a go, but now I'm thinking of doing eVGA's step up program and getting the 6800GT :p:

[gianvito]

Damn...I'm having problems and I can't format pc now because I must finish a work....please someone measure the Voltage on the card after flashing bios with 1.5V...

[Nubius]

I was hoping mare was checking the voltage spots since he asked for a pic of where they were :D

I figured you'd be able to tell just by if you could overclock more or if your temps were significantly higher, but he's reported no better OC's

[mare87]

I don`t promise you that I will check the voltages, because I don`t own a volt meter and my friend that has one, isn`t at home.

[Plague]

well i would just like to say....i figured out how to flash to a differant vendor's bios...ROFL im so happy.

here is the command..
nvflash -4 -5 -6 <bios>

have fun, although i warn you, you must reinstall you drivers (at least i have to right now)

[Nubius]

Yeah, I was aware of that actually because of this tutorial:

http://forums.nvidia.com/index.php?showtopic=1945&st=0

It's just how to enable temp monitoring, but this was before I knew of nibitor and it's ability to simply click a check box and enable it lol.

So let me get this right....we've had two people flash with the 1.5v BIOS and no problems have occured besides the simple fact we really don't know if it's actually running at 1.5v currently?

[Plague]

im going to flash to 1.5 right now, so hold on 5 min...brb

[Plague]

booted fine, im gonna test if it actually had an effect (overclocking wise)

[Plague]

no differance in OCing, i think we're doing something wrong here..wish some of the more experienced modders would help

[Nubius]

well, we're changing the hex....that's all we can do, so if it's a hardware limitation it's simply just not gonna go to 1.5v....lets hope it doesn't revert to something even lower though. So if 1.5v doesn't work perhaps it's just best to reflash with your known good 1.4v regular BIOS and just do a volt mod as that seems to be the only way of actually getting the extra volts.

[Plague]

true true

[gianvito]

Mmm...I've also tested it...no change! I think that VMOD isn't functioning... But if someone can measure it on the card please do it..

[Nubius]

I'm assuming it's a hardware limitation then. I downloaded the 6800GT's BIOS to compare to the Ultra and when you do the 'Extend Voltage Tables' on the GT it will actually show a 1.6v even though I believe it runs at 1.3v normall.....so I think if you can't have the voltage be shown it simply wont work even when editing the text. Just my guess though. Without someone measuring the voltage spots we wouldn't know for sure....but I'm going to be using the eVGA step up program and sending this card back in to upgrade to the 6800GT so I'm kind of paranoid about trying to measure it and accidentally frying it

[Micutzu]

I'm having problems running two 6600GT's in SLI, one is Gigabyte and the other one is Leadtek ... Whenever i plug them in only one works, and it says to remove the "non SLI-capable" card. I thought of flashing both with the same BIOS but they are of different size, Gigabyte's is 64000 bytes and Leadtek's 64512 bytes, so i just modded the Gigabyte BIOS with Leadtek's settings from Nibitor and re-flashed it ... useless. The mobo is DFI Ultra-D modded to SLI, i used 2X6800 in SLI before so that works ... i was wondering if you guys have any ideas on what else i could do ... any kind of help is welcomed.

[Nubius]

I don't think you're going to be able to get it to work with 2 different companies brand cards.

[Micutzu]

Well, if it wasn't for the extra 512 bytes is Leadtek's BIOS i could probably manage to make it work. I've seen cards from different manufacturers in SLI before (Leadtek + Gainward), so it's not impossible.

[jimmor]

Well, if it wasn't for the extra 512 bytes is Leadtek's BIOS i could probably manage to make it work. I've seen cards from different manufacturers in SLI before (Leadtek + Gainward), so it's not impossible.

Why didn't you just flash them both with the same BIOS. Basically they are exactly the same card from different manufacturers. And bIOS size is unimportant as long as it isn't bigger than 65k !

Presumably flash the card that is not being accepted by the SLI setup ?

[Micutzu]

Well the Leadtek has board ID 4300 and Gigabyte has D700, so i'm thinking they might not be really identical ...

[jimmor]

Many manufacturers appear to have set their 6800GT's GPU volts at 1.3. However, the 6800GT BIOS can easily be changed to set GPU at 1.4 or 1.5v if wanted. Mind you, 1.5v on the GPU is not advisable unless you are using water cooling !

[jimmor]

Well the Leadtek has board ID 4300 and Gigabyte has D700, so i'm thinking they might not be really identical ...

The only main way they can be incompatible with each other, is if one were PCI-E and the other was APG type. But since both in your case must be PCI-E, I don't really see aproblem.

What are the main differencies you know about them. For example, do they have diff memory size and type ?

Do they look different, and why ?

[Micutzu]

No, they're identical as far as the aspect is concerned ... both 128MB and even use the same memory chips. I'm not even sure i could flash a BIOS of a different size on any of the cards though.

[jimmor]

Aright, my file name is BIOSVOLT2.ROM as you can see it's the one I attached above.

I just booted from the floppy and this is what I typed in

VGABIOS -Fbiosvolt2.rom

and it says the following



That's exactly what my screen looks like after I've typed in that command. So as you can see theres no error, no confirmation or nothing.

If I type in just VGABIOS without anything else it'll say VGA BIOS NOT FOUND! at the end.....sooo yeah I don't know if it's working or not

Since VGABIOS is run in DOS, the bios file name can only have max of 8 chars in front of the dot, and max of 3 chars after the dot. Otherwise DOS will not recognise the vgabios command. Your bios filename has 9 chars before the dot ?

[jimmor]

No, they're identical as far as the aspect is concerned ... both 128MB and even use the same memory chips. I'm not even sure i could flash a BIOS of a different size on any of the cards though.

Flashing of a vga bios is very simple, but it must be done in real DOS. Usually using a DOS bootable floppy !

And in your case, it is probably better removing the second card from your sli setup.

So you would Flash your BIOS in DOS using nvflash.exe v5.13

nvflash -r (removes any protection)

nvflash -b ORIGBIOS.ROM (saves original bios)

nvflash -4 -5 -6 BIOSNAME.ROM (flash new bios file)

However because of DOS filename restrictions, "ORIGBIOS.ROM" and "BIOSNAME.ROM" must have max of 8 char's in first part of filename and max of 3 char's in extender part, otherwise DOS will not recognise the command.

And note, the -4 -5 -6 command switches will force a flash regardless of any ID mismatches.

But obviously always make sure you ONLY flash a AGP type card with a supporting AGP bios, and a PCI-E type card with a supporting PCI-E bios !!!!!

EDIT:

People who flash BIOSes, whether they be mobo or VGA, should never do so unless they also know of a recovery solution, just in case of the unknown !

And recovery of a VGA BIOS usually means access to a second, usually PCI, card. Failing that, recovery can also be done by a Blind Flash, where you simply put the Flashing commands in the booting floppy's Autoexec.bat file. In this way the flashing command is automatically run while booting to DOS. Of course, this also requires that you set the Floppy as the first booting device in the mobo bios setup options.

[Nubius]

Many manufacturers appear to have set their 6800GT's GPU volts at 1.3. However, the 6800GT BIOS can easily be changed to set GPU at 1.4 or 1.5v if wanted. Mind you, 1.5v on the GPU is not advisable unless you are using water cooling ! Yeah but nibitor has those higher voltages selectable in the drop down menu whereas to set 1.5v for a 6600GT takes editing the HEX inwhich then if you reload that saved BIOS, the drop down menu won't show anything. This basically tells you that the 6800GT doesn't have a limitation and will accept those higher volts since it's in the drop down menu but not the 6600GT.

Hmm crazy, didn't know that, previous BIOS name was BIOSVOLTS lol so again that's 9 characters...oh well I'm sending in my 6600GT to eVGA and stepping up to the 6800GT sooo I'm not gonna bother with it ;)

[jimmor]

Yeah but nibitor has those higher voltages selectable in the drop down menu whereas to set 1.5v for a 6600GT takes editing the HEX inwhich then if you reload that saved BIOS, the drop down menu won't show anything. This basically tells you that the 6800GT doesn't have a limitation and will accept those higher volts since it's in the drop down menu but not the 6600GT.



NiBiTor doesn't actually measure anything, it only translates the Performance Level Indicator values stored in a BIOSes GPU volts lookup table. The 6800GT's lookup table binary string for 1.4v is "8C01", and for 1.5v is "9603". It is the "8C" and "96" parts that NiBitor translates, but it is the "01" and "03" parts which are used as a bit mask to cause the volts to happen.

If NiBiTor does not allow a proper dropdown menu for your 6600GT BIOS, it is probably because it doesn't yet fully support that particular bios. It is a developing tool, so maybe with next update ?

Flashing of a vga bios is very simple, but it must be done in real DOS. Usually using a DOS bootable floppy !...

:) i'm flashing video BIOS'es since the GF2 era mate, i know how to do it :) My problem was WHAT to flash really, not how to do it. Anyway, long story short, i did it, i flashed a modded Leadtek BIOS on the Gigabyte ... i had to modifiy the board ID from the Leadtek BIOS with the one found in the Gigabyte BIOS, but Nibitor was showing it wrong (D700 when in fact it was 4301) ... a little messing around and i found it, not it's working hehe ! Thank you for the support.

I'm just saying the 6600GT BIOS's dont have it basically 'implemented' like the 6800's do. That's why a lot of people with an ultra will flash with a GT BIOS because of faster RAM timings, but will need nibitor to raise the voltage to 1.4(or was it 1.5?) like the ultra should be.

No problem, glad to help !

By the way, other than by you just telling me, I had no way of knowing how much you know about flashing bioses, or anything else for that matter.

And for interest, why did you feel the need to modify a board ID ?

The -4 -5 -6 command switches of nvflash program are specifically included to ensure that the program will ignore all ID discrepancies.

[jimmor]

Just to clarify things, if only for me ?

My understanding of things is that a typical 6600GT has 2 options in its GPU volts lookup table, "8200" and "8C03", which is obviously translated by NiBiTor v2a as 1.3 and 1.4v. The table can however have 4 positions, ie the missing "01" and "02" options. However not having a 6600GT, I have no info on what voltages either of those bit masks produce ?

On the other hand, a typical 6800GT GPU volts lookup table, which is also four option, will typically show as 1.1, 1.3 and 1.4v. The 1.5v option of "9603" must be added with a Hex editor, because for some unknown reason when added by NiBiTor v2a it shows up as a 1.6v option ?

[Micutzu]

Hmm, i didn't know there was a -4 ... and by using only the -6 command switch i always got "board ID mismatch".

[jimmor]

Hmm, i didn't know there was a -4 ... and by using only the -6 command switch i always got "board ID mismatch".

It isn't actually documented, but the -4 command switch forces a flash regardless of any ID differencies. So it is important to only use it where it is known for example that there is no GPU chip incompatability.

[Micutzu]

OK, didn't know that, 10x.

According to the posting from Micutzu above, a 6600gt can have max of 1.4v via a BIOS option.

And NiBiTor v2a shows your linked BIOS to already be set at its max of 1.4v in both 2D and 3D modes. So only way to get 1.5v is by hard voltmodding to your card !

Also, there are no unoverclockable bioses/cards, so not sure why you should think you have one ?

Rivatuner is a good tool for overclocking, however it is important that you you first enter Rivatuner's database via the "Power User" tab, "Overclocking" sub section, and Enable the "DisableInternalClockTest" option. Otherwise any overclocking attempts will automatically fail.

The Internal Clock Test is the reason many people have overclocking problems when using either coolbits or rivatuner !

Well if you do extend voltage tables you'll only get lower tables....I figured it was all up the BIOS whether or not nibitor would see the ability to raise the voltage beyond 1.4

I also notice that in the GT bios it jumped from 1.4 to 1.6 but 1.5 wasn't available....why? No clue....I figure it has to do with the card makers limitations or something along those lines, because I've already changed the hex for 1.5 voltages, a couple people have tried it and no hotter temps or better OC, so I assume it simply wont work. It's at it's 'hardware limits' if you well, whereas a GT obviously has a resistor that can handle more voltages, and the BIOS regulates it or something like that

Generally what is programmed into NiBiTor is peoples experiences. Where for example with a 6800GT, the 1.6v NiBiTor option only came about because some cards set for 1.5v were measured as actually having around 1.54-1.56 on the GPU. So it was rounded up ?

And yes you are right, it appears many cards, including some manufacturers GT's, can't cope with anything above 1.4v.

[jimmor]

Thats exactly the same as happens with my 6800LE. Which is why I posted that you should disable the Internal Clock Test. It is quite "normal" with the newer generation cards.

I saved my bios file with savebios. I changed the 3D volts from 1.3 to 1.4 and renamed with nibitor. Can I flash the newly named file with savebios? It is the same bios as original except voltage increase. I don't need any switches do I? Just pic the "flash single pci-e/agp card" option, yes? thanks.

I have never used SAVEBIOS for flashing bioses. And athough SAVEBIOS can save bios images, there are generally better tools to use.

Bios flashing functions for a 6xxxx series card are normally done as follows,

Flash the bios in DOS using nvflash.exe v5.13

nvflash -r (removes any protection)

nvflash -b ORIGBIOS.ROM (saves original bios)

nvflash -4 -5 -6 BIOSNAME.ROM (flash new bios file)

However because of DOS filename restrictions, "ORIGBIOS.ROM" and "BIOSNAME.ROM" must have max of 8 char's in first part of filename and max of 3 char's in extender part, otherwise DOS will not recognise the command.

And note, the -4 -5 -6 command switches will force a flash regardless of any ID mismatches.

But obviously always make sure you ONLY flash a AGP type card with a supporting AGP bios, and a PCI-E type card with a supporting PCI-E bios !!!!!

[mare87]

Finally bought a multimeter. On my Leadtek 6600 GT AGP with the modded AND with the original bios multi shows 2D voltage: 1.34v 3D: 1.57v. So there isn`t (yet) a way to have (in the bios) more then 1.4v on the GPU.

[jimmor]

Here ya go dude. I've attached your BIOS file and changed the hex which is supposed to make it 1.5v according to the posts above and throughout this thread. Of course make sure you can unflash if anything goes wrong and I've renamed it so that you can keep the original on the disk too, as a backup, but I changed that one and only option for you like you wanted, so let us know if you can get a higher core clock or if everything goes smoothly.

Hi Nubius,

Just checked the bios you linked, and see that you only changed the Performance Level Indicator Value (PLIV) for 3D mode to "96". And although a PLIV of "96" will normally be interpreted by the driver as wanting 1.5v; setting a value that is not actually used in the gpu volts lookup table can sometimes cause the driver to do strange things.

However, fortunately in this case, the "96" value is higher than anything stored in the gpu volts lookup table, so believe only thing that will happen is the driver will just force gpu volts at max available from the card.

:)

Not sure I understand your statement ?

If you are actually measuring 1.57v on the GPU, why would you think that the bios can't set more than 1.4v ?

[Nubius]

Well if it was in the volt table I wouldn't have had to manually set it in the hex, but this is what leads me to believe that there's possibly a hardware limit on those cards that will completely prevent it from even running 1.5v through the BIOS

The guy who asked for it to be changed, already tried that BIOS, but nothing happened, no temp raise, no better OC'ing, so I guess it's safe to assume it didn't work

The max indicator value in the gpu volts lookup table of that bios is "8C". And assuming your bios mod just changed the 3D mode PLIV from "8C" to "96", then in effect it worked. But as I said, it only worked because the driver simply forced the gpu to max volts. Which in this case just happened to be the same gpu volts as would have occurred with a PLIV of "8C" !

Hey moddalicious could u mod my bios I alraedy tried the one from http://mvktech.net/ site rev 2 for my bfg tech 6600gt oc and it was not stable was slow when opening menus for card settings. Stock speeds are 525/1050 I tried opening the bios with nbitor and noticed that under the vender box it reads chaintech but my card is a bfg, anyhow could u mod my bios for more voltage 1.5 would be nice thanx. :woot:

Hi modders :rolleyes:
i'm new on this forum, becouse recently buyed a fake pny 6600 128Mb agp (don't see 64 Bit memory in specs) :mad:
After reading a lot of thread ,trying to mod & flash the bios cards & 15 min of panic (vrong bios in cards) i recovered and installed the original bios bios!!
Now i can ask u to mod my bios? voltage ,remove block if present enable the termal sensor & do all to perform better this card if possible !!

there my info taken from rivatuner (no softmod possible , but i think is normal on my card) :

Graphics core : NV43 revision A2 (8x1,3vp)
Hardwired ID : 0141 (ROM strapped to 0140)
Memory bus : 64-bit
Memory type : DDR (RAM configuration 06)

Memory amount: 131072KB
Core clock : 497.250MHz
Memory clock : 261.000MHz (522.000MHz effective)

now is whit defoult cooler,stable but i think to change !!

i attach my bios version 5.43.02.46.52

ps : original clock is cpu/mem 300/500 mhz

Tnx

Here is my bios could someone mod it so I could have more voltage. Thank you!

[Micutzu]

You might want to get it again, it has only 60928 bytes instead of 64000 or 64512. All utilities say it's corrupt.

[Mavke]

Indeed that BIOS is corrupt, did you use nvFlash for making the backup?

[ReelMonza]

What about undervolting and underclocking ?

Is it safe to set very low clocks and voltages for 2D mode and have stock clocks back in 3D mode ?

I mean running like 100/100 for 2D and then 500/500 for 3D.

I'd really like to cool down my 6600GT and turn fan speed to silent levels.

[njkid32]

Not to sure your talking to me but I used savebios and just created a zip and it compressed to that size here is a second try..

[Micutzu]

Just use nvflash to get the BIOS ... boot in DOS mode and run:

nvflash --save bios.rom

The file you have attached is too small and is not a complete BIOS file.
But leaving that aside, eVGA's already come with 1.4V for the core, so there's nothing more it can be done, except for a hardware mod of course.

One question: Ive never flashed a video bios before, but read how to do it. I've attached a copy as from savebios, but this saves it as a .BIN file. When I flash it, shouldnt it be a .ROM file :confused:

A graphics card BIOS can be or .bin or .rom extension. SO that is not the problem. The problem is that your BIOS is corrupt! Never use SAVEBIOS! It is only okay for older cards like GeForce 4 Series. You should use nvFlash to make a correct BIOS. Make a bootable DOS floppy put nvFlash v5.13 on it and then start your PC from that floppy and execute:
"nvflash -b backup.rom"

Then you zip up backup.rom and attach it here, and that will be a valid BIOS that can modded... ;)

Well, I managed to edit my bios using thr nvidia bios modifier and reflashed it. i set it at 1.5V but this doesnt seem to improve overclockability. With stock voltages, I could push it to 565/1197 MHz (VGPU/GDDR3). After modding the bios, the core only goes upto about 590 MHz, but i have to reduce the frequency of the ram to 1.18 GHz. Even at those settings, i get artefacts wheras with stock voltages and 565/1197 MHz everything runs OK :confused:

Did anyone actually get higher clocks after modding their BIOSes? And, there is an option to set it to 1.7V, but i didnt as i cant verify that this would work or if it would render my card unusable. Has anyone actually done this?

Thanks :)

Mmm, well I wouldn't using that modifier... It is not always correct at modding voltages and some people have had issue with their cards after flashing with a modded BIOS from that tool.

One thing that mat be worth mentioning is that it wouldnt flash using
"nvflah -p -u -f hack1.rom"

only worked with

"nvflash hack1.rom"

Using the first command, it came up with all the things like an explaination of the different tags, etc :confused:

Anyway, my BIOSes are attached below. Backup.rom is the original and hack1.rom is the one i edited.

Currently, im running on Hack1.rom. I experience no problems at the previous settings (565/1197 MHz). Should i keep this bios for the time being or re-flash to the original?

Thanks :)

[Mavke]

Well you are using nvFlash v5.xx so those commands options have changed!
"nvflash -5 -6 newbios.rom" (Normal Flash)
"nvflash -4 -5 -6 newbios.rom" (Forced Flash)

And euh use NiBiTor to make any changes!

[K.I.T.T.]

nibitor wont allow me to raise the voltages over 1.4V :confused:
however, the one that i flashed previously reports 1.5V in nibitor. Would using the nvidia bios modifier and changing it to 1.6V help?

[Mavke]

Yeps indeed that is because the voltage table of NVIDIA doesn't have a 1.5v setting and that is why if you use a multimeter you will still get around 1.4v on the GPU...

[K.I.T.T.]

So i wonder why the voltage was set to 1.4 initially :rolleyes:

Ah well, what do you think of the speeds though? 565/1197 MHz? Not too shabby are they? :(

Maybe its time to get the old 4B pencil out..... ;)

Hallo especially moddolicous,

i have already save my BIOS and load up to MVKTech for a while, but nobody could help me, cause my card is very special. It is the "MEDION 6610XL": A special-version of the GeFORCE 6600 GT from MSI for a big German company like DELL. The card have a NV43 and 128 MIB GDDR3 from INFINEON on it. She runs very great from 400 MHz GPU & 400 MHz VRAM (DDR800) up to 561 MHz GPU & 513 MHz VRAM (DDR1030). But now she do not want more to clock higher. I have already buy a ZALMAN VF700-Cu and add some of this new High-End from Germany http://coollaboratory.com - but it did not help, the Card goes cooler down to 35 °C, but i hang still at the same clock, with artefacts with higher clocks.

Please moddolicous, could you take a look on my BIOS and higher the Voltage to the maximum (I think 1,4 Volt or 1,5 Volt is possible) and higher the Boot-Clock from [400/400] to [555/500] for all situations (2D, low power, 3D) in your Editor? I have save it with "savebios.exe": http://www.ttecx.de/VIDBIOS.BIN

Thank you very much in forward,
with greetings from Germany.

Tobias.

[Mavke]

I have save it with "savebios.exe": http://www.ttecx.de/VIDBIOS.BIN
The BIOS saved with savebios.exe is corrupt as savebios.exe is not designed for saving the new BIOS (newer then the GeForce 4 Series). So pleas use nvFlash and then at least we can take a look... I didn't see any of this on MVKTech... (hmm might have missed that).

I'll try and take a look. Is it AGP or PCI-E?? And also, did u say the stock clocks were 400/400? And lastly, if u can, try to back up the bios with nvflash. Savebios usually messes up with newer cards like mavke said.
