hi.. i got a Point of view 6800 ultra and the stock speeds are olny 370/1050..
dont know why maybe a new revision because i got a 6800ultra with only one powerconnector.. but i am sure it is a ultra and not a gt because on the package it says ultra and also in my graphic menu it says 6800 ultra
so i would need a POV bios with the normal ultra speeds @ 400/1100 or 425/1100
pls make me one... thnx
No way cause a ULTRA has to be at least 400/1000, they said this publically to fool ATI as we all know then manus made it 400/1100 with some making them 425/1100 like my Chaintech, which btw unlike some makers like BFG dont claim to be 10% o/c, Nvidia dont tell makers what speeds, they give them a range and that the range they work to, a ULTRA E HAS TO HAVE 450/1200, i can easily run more than this now with no mods and 100% stable in 3d marks with no artifacts or bit higher again like 470/1220 with artifacts in 3d mark but ok in games, my temps dont seem to increase, obv i could work this better with modded bios, im think that over for now.
There used to be point of views avail to preorder where i shop online and it wasnt that low it was approx same as others ie 400/1100, but most of the ULTRAS aint appeared as of lack of them so they have removed most makers from list.
jeah.. but it couldnt also be a gt because a gt is @ 350/1000 clock speed
did you buy new or someone or you flashed the bios ?
Yeah but it couldnt be an Ultra cause it isnt set at 400/1.1 and doenst have two molex. Sorry, but that's the truth. These two things are required to be called a Ultra. Did u buy this from a store?Quote:

Why don't you take off the heatsink and look at the chip itself. It will say either Ultra or GT.
Tell us if it will run 400/1.1 stable, like really stable, in a hot room etc under full load for hours.
I'm not going to speculate, but that sounds kinda fishy to me.
http://www.pointofview-online.com/pr.../6800ultra.php
look at this, notice two molex and 425/1.1 on POV's own site for 6800 Ultra
Maybe you got a HYBRID :banana4:
sry for my late answer i was away the whole day...
to drcrawn: i oc to 400/1100.. i can run any benachmark with it.. i tried 3dmark05 with 370/1050=4629, an than 400/1100=4800, and 3dmark03 370/1050=11636, and 400/1100=12014, no problems so @ benchmark... but i tried far cry than with 370/1050 everthing works perfect @ 1280*1024 every detail on very high and 2*anistrophic filtering... than i tried with 400/1100 there was no difference.. but after 15min playing my monitor freezes and there were many weird lines.. than i reboot and adjust back the stock clocks @ 370/1050
i asked my friend who ordered me the card from amerika and he meens that its maybe one of the first ones that got produced because i alredy got this card since august or september...
but tommorow he will give some more information.. maybe i just have to flash the new POV bios and than everything is ok.. but i meen there was no improvment in games between 370/1050 and 400/1100 so maybe i just let it like it is
PS: i wont remove the heatsink at the moment.. because than i would have to remove many other things to get my graphic card out, like some tubes of my watercooling and thats not very funny and i am really sure that its an ultra because if its a gt it wouldnt say its an ultra in the graphic menu..
Do you know how to copy your bios using nvflash? If so, can you send me the bios through email? I can take a look at it and tell you what's going on...Quote:

well, like the 4501200 bios is so old already , are there any new bioses out there that are better than this?
thanks, first post
Just check here: http://www.mvktech.net/index.php?opt...er&filecatid=4
ok thanks, now im using a nibitor-modified bfg bios (thougth that its the safest since its the same brand as my card) .... seems to be on par , like 460mhz core and stuff with the noxis bios... i wonder where is noxis nowadays, or extremetheme... theres gotta be a supa dupa bios somewhere....
how do you guys go at bioses, like do you just get the newest one you can find , mod them, etc etc?also do i really have to use nvflash version 442, and not the newer ones?
If it works why change it.
I can easily run 3d mark 2005 with no artifacts at 460/1219 with no mods to Chaintech 425/1100 Ultra, it tops in coolbits to 470 core as you cant pass test to apply at 471 core but its gets artifacts in 3d mark (similar if memory is above 1220) so prob 1.5v instead of 1.43v would help, my temps dont seem change much, always approx 52C on load in room temp of 21-23C
A Ultra Extreme is only 450/1200 anyhow.
Well I downloaded the latest BIOS and modded it. My card does 6800GT 462//1208 Max
nvFlash 4.42 because it is the onlyone that work with "ignore vendor" "ignore size" bla. bla. something like that :)
Dirt what bios are you using? I also have a Sparkle 6800GT and mine only goes to 434/1200
I sold the card so I don´t know what exact BIOS I ran on the card. But it was a modded +0,1v biosQuote:

Oh btw I´m on watercooling and my temps never go above 60c.
Would you be able to send me your Original BIOS of that Sparkle 6800GT?Quote:

Can anyone help me mod this card?
Is the BIOS I have relatively close to other 6800 BIOS's mentioned in this thread? Can this BIOS be altered to increase my voltage and fix the 25C temp problem I get when I use my water chilling system? What about a hardware mod?

Hello,
I want to backup my BIOS card with nvflash but I have the message "PCI bios not present
note : this program can only be run under DOS"
I typed nvflash -b origine.rom in MS-DOS mode (under Windows XP then in safe mode). And I tried other commands like nvflash -c (check)...and it does not work too. It seems that nv flash does not work with my BIOS card.
I tried nvflash 4.42, 4.46, 5.13 with the same result.
On the other hand, I managed to backup the BIOS with Xbios Editor. But that does not solve completely my problem since I cannot flash the bios. And OmniExtremeEdit FX 1.5 does not find any information when BIOS is loaded.
So, would you know how to make nvflash work ? Or what other tool could I use ?
My card is a Gainward 2600 Ultra Golden Sample and the present BIOS version is 5.40.02.15.06.
In MVtech site, I found the same BIOS version. I explored it with an hexadecimal editor and I do not find 2D and 3D voltages and frequencies. I have read that GPU 3D voltage is located int E683 address, 3D GPU frequency is at E56E address and DDR3 frquency is E573 address.
So, would someone know where to modify the 2D and 3D voltages/frequencies in 5.40.02.15.06 Gainward bios ?
Thanks for your answers.
overclock,
You need to flash from a DOS bootable floppy.
Read this: http://www.mvktech.net/content/view/15/37/
As for the voltage questions I don't know, I'm a newbie at this so I need help myself... :D
Thank you, nvflash works now. It did not work because I used it either in MS-DOS in Windows Xp or in saffe mode, but not with a bootable floppy.
But, all advice concerning the gainward Bios mod is welcome.
Would you know how to protect oneself in case of accident when flashing ? I have read using a PCI card or using a bootable floppy disk with autoexec.bat containing nvflash -f -5 -6 backup.rom, which loads automatically your original bios file if the card does not work anymore. Would you have tested it ?
Thanks.
I dont really want to search this whole thread so can somone point me to the best BFG 6800 Ultra OC bios? Is there any bios's for this card with the GT mem timings but still an ultra bios? thanks!
Hello Tony,
You can visit http://www.mvktech.net/index.php?opt...er&filecatid=4
You will find many Nvidia bios but I don't know which is the best for BFG 6800 Ultra.
too many bios's... id rather use one that somone has gotten thier best results with...
I can mod a bios for u, but I dont know how to do the mem timings/ or if it will be safe at those timings. Just post what u want me to do and the make of the card.
its a bfg 6800 Ultra OC which is the reference nvidia 6800 ultra. I use GT bios's for the timings and no 2d profile...my only question is which is the best bios for the default nvidia pcb?
My 6800GT only make 375mhz for the core, if I put the bios 1.4vwill be better? where download the bios?
thx guis my english is bad :(
With the 1.3v that a 6800GT is normally set at, I am surprised you only manage 375. Especially since my 6800LE works no bother at 400 with same 1.3v.Quote:

I must warn you however that some 6800GT cards don't like 1.4v on the GPU, so you do it at your own risk !!!!
I've got a BFG 6800 Ultra OC, and while I'd rather do a voltmod for the core, I would like to know if there's any word on whether there's a fix for the temp issue...
I've seen the LN2 w/r on sli'd 6800's and they must have done something with it...
I've got a 507'd Prommie all modded to mount on it, and I'm just plain itchin' to get it on there, but there's not much point if it's just gonna throttle down...
Hey moddolicious, you wouldn't happen to be able to write in a fix to the bios and possibly a driver fix, if required, to make it happen would ya? :hump:
Gray
If you mean the higher than normal temp reading in drivers tab, that was bad drivers and is sorted in new oned on nvidia site.
I have a Chaintech 6800 U its 425/1100, not claiming to be 10% o/c
Ive ran it upto 460/1219 on standard bios and then i grabbed a modded bios from a GT as its got tigher ram timmings, even at 425/1100 the difference with the new bios with same volts was 300+ in 3d Mark 2005, then i modded bios to 1,6v but only get 465/1225 with NO artifacts in 3d mark 2005 as im on normal cooling, core never goes by 65C on load but i dont know how hot ram runs.

Nah it's the freeze bug I'm looking to sort out...
I've noticed a few using extreme cooling on their cards, and not having a problem...is that sorted out with new drivers, or is it still a bit hit or miss?
The freezer should run -50ish, so I need to be sure it'll work, and not throttle, at that kind of temp...
Guess I'll just have to get it hooked up and see what happens :)

Hi all
anyone have a good bios for pov 6800U PCI-E
i an h2o cooling my card and i cant get over 475 core and 1150 mem
the card don´t get very hot
Wel if you can provide yoru Original POV 6800U PCIE then we can do some changes so that it will run at better speeds... So backup your BIOS and attach it here so we can check. ;)Quote:

1.5v is only just above the daefualt volts for a Ultra anyhow, i run 1.6v on air and no issues gpu temp on 3d never goes by 65C ever on full load with 465/1230
1.5v is only just above the default volts for a Ultra anyhow, i run 1.6v on air and no issues gpu temp on 3d never goes by 65C ever on full load with 465/1230, i only gained slight increase as i could nearly do this with normal volts, but remove standard cooling pads or grease and us artic silver 5 or ceramic
DEVIL DK, try this bios. I just raised voltages to 1.5v. (stock=1.4)
I tried the pencil vmod from vr-zone I can only get 1.67v or 1.77v (went up and down the between 7.4K~8K ohms) which I think is too much unless you're doing -0c temps. I'll do the 1.5v on the bios, by the way 50c is my load temp. If anyone else has any input please go ahead. Thanks.
Hello Xtreme modders, I need that someone plz mod my original bios to get the max volts out of it, if possible make 2 files one for 1.5v and another with 1.6v.
Right now I'm using a hard mod to get 1.69v, hit the wall at 595 core with DryIce, I need more :D
Card is a Gainward 6800Ultra 430/1200 stock clocks.
Here is the file.
You would be better of using the modded GT bios, it gets you 300points increase in 3d mark 2005 at same clocks as default Ultra as it has tighter ram timings, i have this bios and have modded to 1.6v and have no issues of heat, at 465/1225mhz, if your gonna o/c slap some artic silver or ceramic on core/ram and volts mosfets.
I can make your bios 1.6v but not 1.5v as tool dont support or i can give you the modded GT bios with 1.6v,you card will be seen as a GT in windows until you tell rivatuner to rename it to a ultra this requires unistalling/reinstalling driver as we technically are changing card.
Its a 5min job at your end and worth it even if you didnt overclock or raise volts the GT timings gain you a good jump for FREE.
Nice, if you can plz, mod my bios to 1.6v and also send me the GT modded too to 1.6v, I will try both.
That GT bios is PCI-E right?
The file u saved is wrong. If u can, use savebios, and then post it here. BTW, is there anything in particular u want me to do? Up voltage, I know, and what else? (raise clocks)
NO Sorry im talking plain agp8x cards, i not using PCI-E.
Got a reference 6800GT here, wondering if most bioses are compatible with it, or if i should just toss you guys the bios included on it?
Wrong? Just rename it to .rom , I've saved it with nvflash.Quote:

Hmm, I see some of you guys running like 475mhz with 1.5v and my question is couldnt the card hit that with 1.4v? Mine does 513mhz on 1.4v. 1.5v was totally worthless for 24/7 use for my card, all it did was raise my temps 10c. These 6800 want colder temps way before they want more voltage.
You obv wanting to o/c card, well here is a FREE 300 point gain for me at same clocks b4 i o/c it, just by a sinple bios flash.

edit: i've heard a couple of stories about the 1.6 volt, as in some say it works and some say it doesn't. if it can work, i would like 1.6 volts since i'm on water cooling
It looks like 1.6 may work on evga, because I tried it for someone here before, and it worked. For some other reason, it wont work on others. Here's your bios. Report back here once your done. And no, mem voltage isnt controlled through bios.
did you forget to link to the bios, or did i just overlook it? heh.
thanks a lot btw :D
Sorry, not very smart. :am:
lol, no prob, i've forgotten to attach files countless times...
i don't think my card is liking this bios, i tried overclocking to 450 (already obtainable by my card without mods) and it passed the little test coolbits does, then i tried 475 and the screen got slightly disfigured (all in the while mem at 1ghz default clock) then said it failed the test, i tried to test it at 450 again and no dice, tried at 425 and no dice. it does fine after a reboot, so i'm sure there's no damage, but maybe the 1.6 didn't work *shrugs*
alright, i did some testing, and what i came up with was indeed very weird and unexpected... anyway, here goes:
(all tests done at default clocks)
default bios
2d: 1.331
3d: 1.325
idle: 42C
load: 45C
1.6v modded bios
2d: 1.530
3d: 1.524
idle: 42C
load: 46C
using gtu bios from http://www.bleedinedge.com/forum/showthread.php?t=7215 (supposedly only mods your bios to make your core 1.5v)
2d: 1.130
3d: 1.425
idle: 41C
load: 48C
is this normal? maybe the spot where i'm measuring it has a little bit of resistance in the solder throwing the readings off or something, i dunno. i read it from the spot shown in the first picture here: http://www.vr-zone.com/?i=926&s=1
i seem to get the best overclocking ability from the gtu bios, stock does 450 but with some minor artifacting. with the gtu version it takes away the [very] minor artifacting, but i can't seem to go any higher without artifacts, and it straight up crashes when i try 475, although it passes the initial test in coolbits. your 1.6v version for some reason crashes when i try the test at 475mhz.
i may try more, but all of this has me a little scared, i hope the card can handle it. it can certainly handle it as far as temps are concerned, as you can tell lol.
what has me worried is the volts aren't what they are supposed to be in any case (1.5 is actually 1.425, 1.6 is actually 1.524, 1.4 is actually 1.325) -- this might be normal though *shrugs*
i seem to be hitting a barrier of some sort at 450. i could do 450 core on my original bios with no mods, but i had very mild artifacting. with the gtu bios it seems to get rid of all artifacting, but if i try to go any higher i get artifacts (pretty bad ones too). with yours, it goes to 450 just fine, but if i try and do the little coolbits test at anything over 450 (even 455) it will artifact the screen then report that the test failed.
i wonder what might be causing this :confused:. one thing i do think i should try is trimming my pots for my 12v line, my 12v line is actually slightly over 12v, which i was thinking might cause a problem (it's ~12.13). it's a fortron blue storm, so it has voltage pots, i just didn't want to mess with the defaults.
oh well, sorry for posting so much lol. i'll report back i guess if i can find a way around this.
hi and thanksQuote:

6E00 = 1.1
8202 = 1.3
8C01 = 1.4
9603 = 1.5
Any bioses out there which don't adhere to these structured options were moded by people who either, didn't understand gpu volts selection and operation on 6800 cards, or, were using older versions of OmniExtremEdit or NiBiTor programs.
The volts you get is hardwired into the card, and is set by the driver using the last two bits (00, 01, 02 or 03) of the four bit volts option string. And the actual volts that gets selected is dependant only on which Performance Level Volts Indicator value is stored in a particular modes performance table.
If you want a better understanding on GPU lookup table structures and how a driver uses them, read the GPU Volts section of the 59xxx bios modding guide linked below. Even although the volts values may differ, the operation of the gpu volts lookup tables of 59xxx and 68xxx bioses is the same.

And the fact that for example your 1.4v setting may actually measure as 1.42 is completely down to tollerencies of components on your particular card.
The 12v line only needs to be kept within plus or minus 5% of its nominal value, which means a max level of 12.6v !Quote:

lol, sorry once again for posting. i was getting very worried that i had fubar'd my card when every time i started 3dmark01se it would hard lock the comp with a random garbage screen (one exactly like when i tried the coolbits test at over 450core).... so then i changed my volt pots, actually increasing them a little bit more than default. the problems presisted, then i decided to go at my memory since i couldn't do much with my core, so i was running 3dmark03 and it was doing so-so at 450/1.25, a small bit of artifacting though (memory artifacts, i believe all core artifacts are gone). for some reason i decided to let the test go all the way, lol. it got to the sound test and it ran fine first run (no sound). second run, the same core problem where it garbles the screen with crap. i realized then immediately what was going on, lol. every time directx initializes the sound (notice i can play sounds with no probs not initialized by d3d, and i can play sounds while running 3dmark with no probs) it crashes the card. i think this is actually a directx issue, because i don't think i properly updated to directx9...
this makes me oh-so-happy, because that was my problem from the beginning basically. i am going to do a driver cleaner on my sound card and video card drivers, then reinstall directx the latest version and reinstall them. i think this will give me some good results, because it seems to explain my problems very well, lol.
anyway, just letting people know incase you come across this too.
edit: i believe i installed my audigy 2 zs drivers before i installed directx9 and forgot about installing dx9 all together, and the audigy drivers patch up a lot of dx. i think i installed dx9 later, but it over-wrote what the audigy drivers should have patched making it no longer work.
Hey guys, i have leadtek 6800nu with 128mb of ram.
Could you guys tell me how much voltage would a card like this take on stock cooling?
Also, how do i save the bios to a file?
So, does it work now?Quote:

U can try them, and if the 1.5 is too hot, u can flash to the 1.4v. I would recommend just using the 1.4 though. U can save a bios to a file by either finding it on mkvtech.net or using savebios.Quote:

It works great :) nVidia Bios Modifier v1.1
Moddolicous,
How did you manage to choose 1.6 V in your modded bios ? Indeed, when I use tools like Nibitor, I cannot more attribute more than 1.5 V.
Do you use another tool or do you directly modify the bios with a hexadecimal editor ?
Indeed, I would like to attribute 1.6 V for my Leadtek 6800 Ultra and for my future 7800 GTX. They will be watercooled, so there shouldn't be any problem.
Sorry for the previous question, I found the bios editor on guru site, by clicking paakis'link.
My 6800 Ultra was already flashed with 1.5 V. With this editor, I applied 1.55 V.
Then I checked the maximum GPU frequency and...no change ! It is always 487 -490 Mhz.
It seems that 1.5 V is the maximum for my 6800 Ultra.
Another information : a few months ago, I had followed advice given in VR-Zone forum and I had soldered a resistor on my Gainward 2600 Golden Sample (6800 Ultra) AGP which damaged it : normally GPU voltage had to be 1.7 V. So 1.6 V should be the highest voltage to apply. And, according to my test, 1.5 V is enough, more volts won't improve performance.
My XFX 6800U/512MB before bios mod, default voltage 1.43v Max freguency was 469MHz and now 1.53v max is 488MHz watercooled..
Did you try higher GPU voltages ?
@ Apocalipsis: when I read this thread I see everybody complaining about the card throtling below 25°C. How the hell did u get your card do some 3d marks with dry ice on it's head???
done done and done, my bios is at MaXit
Hi everyone!
Did some unsuccesful modifying on my BIOS with Nibitor trying to raise my volts +0.1v and it gave me less overclockability. Artifacting / crash at 350Mhz. So now I was wondering if someone else could do a better job for me?? I want the volt to go up +0.1v for 3D Mode. I'm uploading my original BIOS for you to have a look at. Thanks

Hi guys!
I didnt have enough time to read this whole thread at the moment, but im wondering that is it really possible to increase voltage only with new bios? :O
If so, can someone be so nice to teach what to do, or mod my bios? Card is MSI 6800 Gt. How much does it seems to improve oc:ing with little voltage increasing, while still using aircooling (VF700Cu)?
I have to go work now, and maybe at evening i have better time to search information by myself, but still im pretty sure i can't handle this only by myself... So little help could be nice.
hi to all.
i need help for my xfx 6800gt.
yesterday i try to bech under my single phase at -35 about in full load with my xfx 6800gt. the card go very well, i can reach 630mhz for core and 1400mhz (and more, the pcb is at 3-4°) for ram but also at default frequency i can't do a 3dmark :( i think that is a problem of cold bug.
who have a bios mod for my xfx 6800gt that i can use under -35 °C?
thank you
