Ok here is what im looking at,, i cant seem to fine the thermal values :(
can someone show me the 7D7D or gt value and what it needs to be.. thanks
btw i have done the volyage increase, that was easy.
http://24.158.154.102/images/hex.jpg
I tried to find it last night for like 30 minutes and still couldnt. Someone show us what to do plz :confused:
i couldnt find anything in 6800nu bios
Well the 7D7D was for 125° core slowdown, maybe your cards have different.
Look in your forceware temp setting there is your max temp written.
my is 135c
anyone can enable the last 4 pipeline?
iam willing to test it
Lo chaps,
I have an XFX GT, and the core refuses to do over 380 in 3d mark '03 :slapass:
I would like to try upping the core voltage from 1.3V to 1.4V and see if that solves the problem. Ideally I would like to hit 400/1100. Cooling is default (lapped the heatsink and used silicon paste on mem. but thats its). Can I upload the bios on here then someone mod's it for 1.4V? If so how do I backup my current bios? I've not messed with gpu's bios' before so I'm not familiar with the utilities used :shrug:
On the GTs the core slowdown is 120° so wouldnt that make the value 7878 or something like that? Ive searched the bios for 7878 but cannot find it. I also looked in the area around the clocks and voltages but it a 78 was nowhere to be seen. :confused:Quote:

120c is the shutdown temp for me and orb.Quote:

0c-100c would be sweet. but looking in hex i can find anything that looks like what yours show.
Dudes I got back my BFG 6800 Ultra and I'm trying to look for the offsets to modify the VGPU but I can't find it!
The offsets are quite different from the pic extremetheme showed!
So how do I look for the values to modify?
convert your clocks to hex, then reverse the 2 number like in the pic and search.
400 in hex is 0190 so flip the pairs and you get 9001 which is how it will appear in teh bios.
Eh, nvm I was an idiot. I found the offsets to change.Quote:

Seems to be working, and helps my Ultra stay stable at 470

Hi, the theory that the slowdown has a 100° range was false, as you can read by shaminos answer in the early pages.
If you change the slowdown from 120 to 100, all you would get is that your card slows down at 100 instead of 120.
Which would be counter productive for ocing. Its doesnt change the slow down at low temperature.
You'll probably find what you need in the zip I sent to rycky. He put it up for download: http://rycky11.free.fr/Forum_Hardware/6800u13.zipQuote:

is there anything we can do then to drop the 25c to 0c ?Quote:

The BIOS is the right one for PNY 6800 GT, but I'm afraid you will have to run nvcheck against it in order to recalculate the checksum, otherwise your videocard will not work any longer :)Quote:

400/1100 and 1.4 vcore.
Looks like all GTs have problems over 380Mhz (like mine was), after this bios update I'm running PNY 6800GT@Ultra with absolutely no artefact.
Good work!
Yeah sorry about that, didnt run nvchk before posting.Quote:

if anyone can adjust the voltage on this would appreciate it..
my card can do 440/1150 right now.. I messed with the Ultra bios from Leadtek and was able to do 440/2000.. but reverted back because temps were 5-10c load higher with the ultra bios compared to the GT @ same clocks..
Thanks..
Great info!
GravY
BFG6800GT
Your temps were higher because you were using more voltage...so upping the voltage on your current bios, is gonna have the exect same results.
I gotcha on that, I should have composed that post alittle better, was in a rush..
can the voltage just to the ram be upped, I could hit 440 before the Ultra flash and after so I don't think the extra voltage is going to help me there, but the ram I was at 2ghz and honestly didn't test past that, so the extra voltage to the ram would benifit me some..
You cant change the ram voltage without a vmod i think.
ok, thanks then, I'll stick with my GT the way it is..
I got the same card as yours and same question...Quote:

my bios date (sticker on the back says)
5.40.02.10.14
card also says xfx, v1.2, 07/04 not sure what that means?!
but your bios is newer date than mine.
Gravy: r u telling us that on your 6800, you got 2.0ghz memory stable under testing??? !!!!!
yuri can u help me get my fx-53(940) stable at 2.7ghz? No matter what voltage I give it, the damn thing won't accept a 13.5 multiplier. 2.6 is fine, even 2625mhz is fine. 2703 is no go even at 1.77v. I might need better cooling for 2.7, but I dunno, my temperatures seemed fine, never above 50c under heavy load. whadya think? Thanks.
Frustrated, I stopped volting the hell out of my expensive cpu and settled at 2613 @1.65 right now.
that was with the Ultra Bios, I stopped testing at 2.0ghz.. it might have done more.. 6800GTQuote:

my 6800ultra mem with the extreme bios does 1.27 no problem looks like. the core, 499 is as high as coolbits has allowed me to go. makes for some nice benchmarks numbers
2.0ghz, i was like whoa there, thats amazing!
Right I've backed up my GT bios...how do I edit it to change the vcore to 1.4V?
Looks great... now I have question... where is the vmem? :P If its hard mod... any one know where to find it?
is it possible to activate all 16 pipelines in an 6800nu using bios upgrade?
if anyone gives me a 6800GT bios with speeds set to: core 325 and memory 700 (350) i can try if that activates them
i tried ur 6800 ultra @ non-ultra speeds bios and it works
dont know how to see how many pipelines are active, so cant say that
however there is no noticable difference in performance and even worse.... in 3dmark it lowers the score (about 700 points in 2k1 SE and about 400 points in 2k3)
the load temp stays about the same as with my point of view non ultra bios, about 68 degrees celsius
idle temp however is about 4 degrees celsius higher now, from 61 to 65 degress celsius
overclocking seems to be the same to, still about 410/825
btw if u need/want my point of view 6800NU bios, ask :)
Well I would like your Point of View 6800NU BIOS.Quote:

Hi all.
Just a question for anyone who may know.
I flashed my S-Media 6800U from it's original bios version of 5.40.02.03.00 to a Nvidia reference rev2 bios 5.40.02.10.15 basically because the original bios the card came with had fast writes dissabled and the nvidia rev2 bios had it enabled. The flash was successful with everything stable and fast writes enabled.
I used commands -2 -p -u -f ####.ROM - "####" being the file name.
However, and here in my question lies. During the bios flash there was a warning (I can't remember what it said exactly) saying something to the effect of unable to copy IEEE 1394 GUID not enough space.........don't quote me on that but it was something to that effect refering specifically to the IEEE 1394 GUID, the flash process continued and then stated flash successful.
Now what does that warning message imply????
Has some feature been left of the card after the flash?? I'm just a little worried that I may have lost some feature of the card??
it is recognized as an Leadtech Research GeForce 6800 Ultra [NV40.0].
i dont have a digital camera (or a normal one for that mather) so cant help u with the pic tho :(
btw. my PSU didnt like the 1.4V
1st i had a low quality 350watt that freezed during gameplay and 3dmarking, then i switched to a high quality 300watt which worked perfectly. until the 1.4V mod... after 2 days of running it freezed too, also after putting the non-ultra bios back.
so had to go buy another PSU :S
have a 400watt xtra silent 1 now :)
Ok I just flashed my card with xtremethemes bios but ended up with no better oc. Has anyone a working 1.5v Bios for the GT That definitely works?
there is debate about what the voltage difference if any there is between a Ultra and GT. Can someone please shed some light on this for me. I say they are both set at 1.43, but someone is telling me that Ultra bios is +.1v over the GT bios. this sounds wrong to me. Thanks...
Hi, does anyone have or done the bios fix for the 25c problem on the 6800ultra? I'm kinda uselss with hex editors. How did shamino overcome that 25c problem?
flashed my gt to ultra now. it´s stable at 450 now but no single mhz beyond. scores aren´t as good as before but that might be driver related.
Thank you works great! You forgot the checksum so my card was go blank but i had a pci and now is all good.I corrected the checksum and putted the BIOS on my space.For everyone who wants it here it is:Quote:

Flashed my PNY6800GT with the bios provided by you (ran nvcheck first ). Could not do 400/1100 before. Now I am at 425/1150. Temps about 5-6 degrees higher but not too bad overall. All stable :)

How high do you guys get with watercooling and +0,1 bios? Im intrested in both GT and Ultra OC´s
i hope the throttling issue can be resolved. i just modded up my mcw50-t to fit on the ultra. someday i wish to use it :slobber:
ok: i have an ultra: check these numbers out:Quote:
Originally posted by Dirt

before watercooling or flashing: 467/1.23 highest stable overclock on air and stock vcore.
after watercooling but before flashing: 478/1.26 highest
after watercooling after flashing with Xtremethemes mod bios(+.1v): 499/1.28 highest, normal 99% accepted 496/1.28, coolbits will not accept 500core no matter what...
so, you can see that these cards are greatly volt starved if you can provide watercooling. My core temps never broke 60c with 90f ambiant room temps and a case temp of 40c plus (yuck). Normal room temps like 73f, the core idles at about 33c when warmed up.
i use the mcw-50 block with non-chilled water and the absolute lowest core temp I ever saw was 27c, and that was right at startup with a 66f ambiant room temp. The throttleing begins at 25c, so you dont have to worry about it with normal water cooling. The core will quickly warm to at least 29c is most cases unless your room temps are really chilly, like mid 60s.Quote:

whoa, sorry didnt clarify myself, that is with NO pelt. if u go that route, you will run into the throttling I imagine....
Hi! I also have a PNY 6800GT, that I'm considering putting a modded bios into. Presently mine is completely stable at 423/1000 with idle temps of 62/45 and load temps running rthdribl of 85/61, all I've done is redo the stock heatsinks with artic silver 5.
Do you have any other comments or advice about doing this bios flash, or any problems with your card? What temps do you idle/load at? What size powersupply is in your machine?
rms
Success!!
I used the PNYGT14V.ROM that Crozet posted on the last page of the thread. Looking at in the editor, it puts 2D/3D at 1.4v (1.3v stock) and 3D at 1.5v (1.4v stock). It has the same bios number as my PNY 6800GT 5.40.02.15.01 and flashed right in with no issues!
I've been running rthdribl at 434/1140 in a window (2D/3D) for long periods, and am about to try Doom3 at these settings.
IT RUNS MUCH HOTTER, peaking at 93/65 in rthdribl vs 85/61 before at slightly lower clocks. I won't be surprised if it hits 100C in Doom3, and this is after AS5'ing all the heatsinks. Improved heatsinks can't come fast enough for these cards.
Anyway, I'm delighted with the results
Hmm we have problems with the availibility of 6800 cards here in Europe. Have been waiting 2 weeks for my 6800GT now and its likly to be 2 more :(
At least my Dangerden 6800 card is on its way. Can´t wait to test it with My card and a +0,1 bios :D
i got my 6800 ultra yesterday and i live in wales in the uk! really sruprised to recieve it this early! i had been waiting ages for x800 xt until i changed my order. This card is awesome! my clocks come as 425 core - 1.2ghz memory ( XFX 6800U ) the problem is, it wont really overclock at all for some reason.. if i could get more out of it it would be even greater.
as it stands i am gettin 12k 3dmark 2003 marks with it right now, and i dont think thats all that bad considering i have an athlon xp mobile oc'ed to 2.5ghz.
anyone doing voltage & cooling mods for this card @ a decent price? if anyone here is, let me know.

hey guys, fellow 6800u users. I know some of us have been working on our cards for a while eeking out the performance...
I need some advice, I can clock my ultra to just over 500 core and 1.30 mem, stable on water with xtreme's backupx2 bios.
The temperatures are fine. So my next step would seem to be more volts.
Man this thread has come a long way since those first posts...can someone who vmodded give us a quick update on the correct procedure as the original picture was incorrect right?
Thanks i appreciate it, y'all.
You don't say what motherboard, but there are a couple things to try. First is raise the AGP voltage in bios one or two notches, this often helps stability.Quote:

Secondly you have a highly overclocked cpu, raise both your chipset voltage to the maximum setting and Vdimm as well, and consider a voltage mod to raise Vdd to the 1.9v range. Also adjust memory timings for stability, like 10-3-3-2.0 to around 12-3-3-2.0 at 220-230fsb (assuming CAS2 pc3500).
*Also*, realize not all games will run at the same overclock. Specifically for me Far Cry simply *will not run* at high 6800GT clocks, I have to backoff to 392/990, while doom3 is happy at 430/1040 (after the modded bios).

try to test your 6800U at default speed on ram and CPU. Then you can see if it's the Grafx that make the crash.
A newer bios might be better, but I don't think thats the problem.
I just installed my new watercooling system. With an AquaComputer waterblock for my POV 6800GT card. Now there is a problem, my CPU core temperature is 26C. I know this because I changed graphicscards and started the computer. I don't know the temperature of my GT though I think it is a bit below the CPU and I therefore think it is below 25C.
The problem is, with my waterblock mounted on the card, the system woun't start. There is no picture on the display. I tried to connect the standard fan while the waterblock was mounted to check if the card registered the missing fan and wouldn't start. The card sadly did not start.
I know the card is not broken, so I think the problem is because of a too low core-temperature. Does anyone else have the same problem? Is there a solution for this?
If you know the values to change in the BIOS, xtremetheme, I would be really greatful for an answer.
Tnx!

would the xtremetheme bios work ok on my bfg 6800ultra oc? On stock cooling.
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...

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. :)
