Hi'ya The Runner
don't think the cooling would be up to it......
but i have a BFG6800u'oc with a water cooling bios stock clocks are 470/1100 i modded it to 470/1200,,'dangerden nv68 water block',,,,,i also have bfg6800u'oc bios rev1, 2 and 3, and could set the clocks to what ever you wanted, but if you did you would have to work out the highest stable clock speeds first.......and if you'd want the 1.5 3dvolts, it does put the loaded temp up a bit.......
not sure if anyone has posted this...
a new 6800u bios from MSI... 5.40.02.28.00 :toast:

anybody have good reading about VGA bios nvidia or ati? :)
hi'ya
does anyone know if the graphics mem latencys have been found on the 6800u's yet,,,or if anyone has optimized them for any gain........??
hi all, could sb tell me please how much should I put voltages in my modded bios of Leadtek GF6800U, watercooled, clocked at 450/1210, T 44/31°C.
I don't know for thrtl. voltage? and why can't we go over 1.5V? Is it not safe?
hi,
I'm new to xtreme forum and just discovered this thread. I have a golden sample 2600 from gainward and i was willing to know which was the best bios for it and if it was possible to edit the bios to raise the voltage. I have downloaded a few bios but while editing through omniedit i had crazy core and memory freq so i didn't flash them. I'm stuck at 430/1200 and i hope that raising the voltage would help to O/c the card a bit more.
I also heard that there was a problem with timings too low in the official bios (the 15.06) and that it was the reason of ingame bleu screens and freezing.
Any one could tell me what bios to take or even better link me a "safe" bios with 1.5v or tell how i could proceed?
Thanks all
Is there any chance I can flash my eVGA 6800U to 6800EE? I can't get the EE bios through card registraition :S Can somebody send me a copy of the EE bios?
can i flash the evga ultra extreme bios to my 6800u from POV??
Hello Everyone,
Ok, a small favor if I may: I can't seem to find any Ultra-extreme Bios over at Gainward's site, and wonder if anyone with this card can save me his bios to a file and email it to me...or PM whichever is best.....
It must be the Gainward U-E bios, please.....
All modders out there should take note of my experience: I found that the offsets in the Gainward Ultra differs greatly from for example the eVGA and some others modified here.
If any of you need a Gainward Ultra Bios which I have modified to 425gpu/1200mem and active 1.50Vgpu softmod, I will gladly provide it.
Other than that, I have recorded the offsets and changes in a word document, but can save that to notepad/wordpad format, and post it here should there be any interest.
edit:Just for the record: on standard room temp water I managed 479 on the gpu with default bios, after the mod I can do 489/490. On 3dMark03 I managed a 15579 score with 3.4EE running at 4.16gig, and card at 479gpu/1365mem.
After the mod, I can do 15580, a 1 point difference, with cpu at only 3.90g, and card at 490gpu/1365mem. So, well worth the effort in terms of cpu benching stability :)

I found eVGA's UE bios but it said it didn't match my current video adaptor. So I can't flash my 6800U to UE right?
Hi MarilynMX,
Ok, I am not professing to know to much about current adapters, point is that is both are based on the same reference design, which I am sure it is, then there is no reason other than quality of component why it would not accept the flash......of course you will have to force the first flash from 6800U to UE due to the fact that it will tell you that the hardware is not recognized.....
I am going to flash my 6800U Gainward with the Gainward CoolFX GS Bios tonight (South African Time - GMT+2), I already confirmed bench/gaming stability at 480/1200, so this card can safely handle the 450/460 spees of the GS-series......
I will keep you posted of my prowess, and the flags I used......you do the same :)
Br,
MrBean.
nvm I just did it with -5 -6 parameters since -p -u didn't work for me
new bios allows my card run default 450/1200 in 3D mode :D
Guess I'll have to get a new HSF or WC system for this card, it runs HOT in benches :(
Thank you MrBean for keeping me posted :) I'll share my experience with anyone who needs help flashing their Ultra's
Thats good news, MarilynMX, so U-E speeds is then by default 450/1200...well, I anyway edited my bios last night (hex-editor) and flashed it to the 450/1200 default speeds, I also upped the vgpu to setting 03 for 1.5vgpu, but it is not needed, only for benching past 479, as my card is really very stable and game-playable at anything up to 475/1250 with std bios voltages!
These Gainwards are nice cards, I have 2, one in my Wife's gaming rig, the other in my Benching setup, and both get at least 470/1250 with Cool-Matic waterblocks.
So I can highly recommend this watercooling solution, or you can get the Dangerden one.....
Will let you know what the CoolFX bios does to my card.....I hope it will unlock the Expert settings in Gainward's Expert Tool......and let the clockspeed go past the current 470 limit :( I am using either Coolbits or Rivatuner to get past the limitation, but I think the Expert Tool might be better, as it doesn't test your settings before it sets them...lol...
Speak to you later.
Hello Guys,
Ok, some feedback: I flashed my Gainward 6800U with the CoolFX Bios, and it worked ok....well, no problems with the flash, etc, booted fine, could even do benchmarks....
One thing I noted though, is some slight artifacting around 475gpu speed, in 3dMark03, where the Trolls are playing their chess game....I see some pinpoint lights on the 4 chess pieces.....which I don't see, even at 489gpu speeds with my standard 6800U bios.
I cannot overclock as high either with the Coolfx bios, and when I do optimized calculation to determine max overclock, it gives around 466/1230, whereas my std Bios gives 477/1260 or so.
I compared the 2 bios'es in hexeditor, and besides the standard ID bytes, there are a few other areas where there are differences, which I think may be the memory timings....
So yeah, besides the fact that it unlocked the CoolFX button in the ExpertTool control panel, which allows quick setting of speeds to Enhanced CoolFX speeds at 450/1200, it didn't do much for me....which was expected. Even the vgpu is set to 1.4 in the bios, so I decided to edit my std 6800U bios and adjusted the vgpu to 1.5.
So my overclocks are around 489/1365 with the new bios, same on the memory, but 10mHz up on the gpu. Will play some more and keep you guys posted.

MrBean.
To MrBean, do you know how to change slowdown temperature shown in NV menu? I want to mod it from 115 to 125. I looked some early posts but I couldn't find a way to get those specific digits:(
@ MrBean (or someone else): do you know, how to mod the BIOS so it don't throttle anymore down when the Core gets too cold?
i'm going to cool the GPU with T.E.C.
so as far as i can tell, when i am done mounting my Vapochill XE on my 6800 Ultra, it is going to force me to run at stock clock speeds and as of right now there is not fix for it? omfg this is terrible.....
sigh, no one has a fix for this yet.....:(
Hello guys!
I wonder it there a moded bios +0,1 and 450/1200 for 6800GT 256MB PCI-E or could someone please help med with it? Im quite sure that I will ruin the card if i try it my self :(
i noticed that there are a couple bioses that have a core slowdown temp available for adjusting using Nibitor and then some the core slowdown temp is disabled completely, along with the timings. is this possibly something that can answer the thermal throttling?
OK peeps, i have read some of you having probs with overclocking after so many % in coolbits, well coolbits only lets you go so many % over default clock then you need add new reg entry called BART, as most know coolbits aint a proggy or app, its simply a new reg entry to unhide already there nvidia settings, you can type it in manually.

All i want to know is, i got a great Chaintech 6800 Ultra @ 425/1100 (3d clocks) out the box.
Its not extreme cooled but only runs 52C max ever so can i flash bios to say EXTREME wihch is said not to exist lol, and what volts increase and clocks will i see, and will it cool ok as it is. ?
It does 468/1210 slight artifacts in 3d mark tests when new, i will try now its ran few months.
WOW. Nice to see this thread is ALIVE. Takes me back...
for those of you who are sub 25c on the gpu, best thing to do regarding cold throttle is to get a bios with 2D and 3D voltages set exactly the same as well as clocks. Just be careful you dont destroy your card, as the built in fail safe has been disabled in effect. Dont even think of doing this unless you have chilled h2o at least...
Check out omniextremeedit bios editor at www. mvktech .net. You upload your bios and can fiddle around with it in terms of voltage and clocks.
Actualy I have created a new thread since this one was kinda dead: http://xtremesystems.org/forums/show...5&page=1&pp=25Quote:

Well it seems active to me upto and inc DEC 04, pci e is no good to me and lots of others, im not ready to go amd 64bit as i got a nice 2.8gig 450fsb mobile 2600 soon hopefully to be 500fsb, but i still like my info i requested on the 6800Ultra. :)
