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:

doh.. 1.2 yes... my bad, I think im going retarded sometimes..
You mean 1200MHz right? There's no memory that can do 2000MHz ;)Quote:

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:

PNY 6800 GT
400/1100 and 1.4 vcore.
xxorbxx PNY 6800 GT @400/1100 ,1.4V (default 350/1000, 1.3V) :
PNYGT14V.ROM
Just wanted to say Thank You to xxORBxx!
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 :)
HI!
Did anyone already succeed in overwriting this down-throtteling issue?
Great Im gonna try this out as soon as I get my Sparkle 6800Gt in the mail.Quote:

Btw does anyone know if a Maze 4 block will fit without modification?
Thanks
yes this is a good question, as I am sitting at 27c celcius ambiant core right now...and at 25c all sh@t goes to hell, lolQuote:

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:

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.
