i got my GTS bios over at www.mvktech.net, but i supposed the one above will work fine.
GPU-Z doesn't really work with it, cause nvidia's drivers aren't installed, just generic windows vga drivers.
here's an image of it: http://img98.imageshack.us/img98/31/gtsbiosii6.jpg
Same here.
The card's device id is 610.
Normaly GTS has 600 and GT has 611.
Maybe a protection or its because of the missing sp units.

yeah, your right about the device ID. Weird thing is if you read it back from the card using Nibitor, it says 600.. but GPU-Z says it is 610. which must be what the drivers think it is as well, since they say there are no recognized devices to install the drivers for.Quote:

That is what i did.Quote:

Maybe there is any difference with an official GTS driver.
Could you get a voltage gain?
The GTS has 1,15V in bios.
My card has a v-mod, so i could not measure.
i can't really check, cause i am at work and was doing all that via VNC... until i decided to run atitool to stress it.. now my computer isn't responding over VNC anymore... i guess it locked up the videocard.. or black screened.. will have to check when i get home.Quote:

seems odd that that would happen, since it gets a GPU mismatch when going from GT to GTS as well, which i over rided using the switched you list above. guess i'll let you know when i get home and attemt to reflash mine back to a GT.Quote:

I had a look in GPU-Z Database, there are many cards with different gts bios versions.
.25
.26
.39
.49
Most cards are not complete recognized as GTS 512 from GPU-Z.
The only two cards that GPU-Z shows correctly, use the 169.06 driver.
But all cards are recognized as device id 600.
Well, let's give it an other try with a newer bios and gts driver.
it's allright all it's ok...
I notice that both the GT and GTS say A2 revision for the chip.
If it isnt a GPU-Z problem, then perhaps there is some hope that the SPs are not cut.

http://rapidshare.com/files/74864296/xfx.rar.html
All I do is change extra to 1.1v and not mess with VID's?
My extra mode is blank. I could select 1.1
This was supposedely the stock 8800GT from EVGA but it came at SC speeds
using 1.1v is cheating. Did you add that yourself, or did XFX actually do this for their lowest end card?
Correct, that's all I did on my EVGA KO and it worked.Quote:

I realised quite a while ago that bioses does make a dif in overclocks
12.00.26 gave me the best overclock.
To summarise, if you want to try the GT to GTS flash.
GTS bios
Needs the latest NiBiTor v3.6
169.06 drivers Vista32 or XP.
Using Nvflash -4-5-6 command to force the ID.
Second that.Quote:

@fornowagain
I can confirm that the 169.06 driver works with folowing G92 cards
NVIDIA_G92.DEV_0600.1 = "NVIDIA GeForce 8800 GTS 512"
NVIDIA_G92.DEV_0611.1 = "NVIDIA GeForce 8800 GT"
NVIDIA_G92.DEV_061A.1 = "NVIDIA Quadro FX 3700"
There is also an new G92 based Quadro FX 3700.
Got a link to that bios?Quote:

Strangely enough, I still do better with .26. I'll try .01 and .02 next.
The 1.1V Mod does NOT work for my card.
If someone could please rake a look at my BIOS.
Well I tried .80 and no dice. I can't overclock my memory even 1 mhz past 900 mhz for freezes etc.
I took a look at it and it's because you haven't placed the 1.1v for the Extra voltage. I have edited it for you so back to you it goes. Let me know...Quote:

I have chhanged it and flashed it and it does not get me any higher clocks at all
Flashed a modded eVGA 8800GT SSC BIOS with modded RAM timings to my Palit 8800GT. Got this so far:
http://www.cyberimpressions.net/imag...GBTweaked2.jpg
Not doing too bad. As far as non-hardmod tweaks go, I am about out of options. Next step: volt mod.

Linky
There's 2 there. One with the RAM left alone and one with the modded timings.
could you upload the bioses here
Thanks...:)
can you upload bioses here
Here you go...the RSSC has the higher clocks with the 1.1V option and the second one has the same except with looser ram timings.
No problem. Here you are.
JINX! lol nice simul-post.
Already posted bro, look at post #313 :)Quote:

I also change VIOD03 to 1.1v like the first post of this thread and does nothing
Here is my original BIOS
*without 1.1v mod*
What brand card do you have?
OK everyone should try this bios, rev 04 of evga 8800gt sc, i mod the volt to 1.15, here is the bios, enjoy.
bios is dated 12/05/2007 newest bios for the 8800gt yet.

I would not flash that bios until editing the clock speeds as well. GAR, the 756/1890/1000 is a "little" high for most 8800GT's you know...:D
I know bro, i forgot to mention, also i know putting 1.15v doesnt give it anymore voltage, but i thought id give it a shot anyway. hehe as long as its over 1.1 we dont have anything to loose.Quote:

My Point of View 8800 GT (with new Cooler)
has this Voltages without any mods:
http://img520.imageshack.us/img520/8...tagezo7.th.jpg
I try to change the Voltage with nibitor
and I see this in the BIOS:
http://img525.imageshack.us/img525/4449/nibitorum5.jpg
Change voltage to 1,2 V has no effect.
look to the BIOS in the Attachment
Well...I decided to use my original BFG OC bios and just change the clocks to 700/1750/950 and nothing else (ie - no voltage change) and I am now able to overclock much, much higher. Go figure???:confused:
From my experience if you try to flash higher than 1.1v you end up w/ 1.05v instead of 1.1v, so set it to 1.1v or you won't get any improvement.
Don't mess w/ anything in the VID Mode tab. That won't do anything for you, and you might make it to where the 1.1v mod won't work. Just go the the Exact Mode tab and change Extra to 1.1v. It will either be blank or say 1.05v before you change it.
It seems some cards come from the factory w/ 1.1v, so those folks might not get any better results after the mod, but they usually get high clocks anyway.
Sorry , i dont read the whole topic.
I need a simple answer for this: is here any bios whit i can manage higher OC ? ( More voltages, etc ).
I have a Gainward 8800GT, thanks.
Changing only the Extra V to 1.22 gave me 802mhz on the core,unmodded with water cooling.
are you sure that the real vcore it's 1,22v ?? :(
Me i can put the vcore what i want the vcore stay at 1,1v :(
Can somebody try the attached bios an measure core voltage?
It gave me a little higher voltage as the 1,1V setting.
Don't wonder that there is no entry for extra in exact mode. ;)
Stock GT clocks and looser timings from an EVGA SSC card with 1000MHz mem.
i`m sure it`s not 1.22 but i only care about the clocks.Quote:

hi people, after flashed my pny 88gt card, after days card this making one beep acute... what this happening?
PS: im restored the original bios, but is not resolve the problem
Just measured the voltages ( vGPU ) at my Gainward ( stock bios ).
Idle : 1.11v
Load : 1.14v .
So.. for me this mod is useless?
have your Card also the new Cooler?Quote:

with this card you can flash BIOS with 1,1 V and you can increase your OC results
secound with new Cooler and 1,1 V
with this card BIOS Flashing dosn't have no change to the OC results
Pes 2008 crashes at 1000mhz mems for me as well, FYI.
Tested but it didn't change my max stable OC :/Quote:

I might also have reached the limit of my GPU in that case. But I'm in Malaysia and ambiant temperature is quite hot here. I'm hoping that with better cooling, I'll improve my OC results. But it is difficult to find a nice cooler here. The only one I can find is the Zalman 900 fatal1ty and there is no way I put anything in my rig written fatal1ty on it :ROTF:Quote:

I'm a bit behind the times on what bios will be best for me. I got an EVGA 8800GT regular the 3rd day after release at Frys (real retail store even!). My god what were my original clocks, hehe. Anyway, I'm already at this point with my OC. Is it worth trying to flash?
8800GT 512 Evga 721/1802/958
HR03GT (120mm on low) 40C Idle 53C 3D Mark 06, no arties, all is smooth.
And there are so many bios versions floating around on this thread, if one is for me please let me know, thanks.
Also, would love to see a summary of this thread and a sticky, this is a huge subject with so many peeps getting the 8800GT. Glad I got mine, got lucky getting mine.
Anybody tried flashing their 8800GT with a 8800GTS bios?
Do you think its possible to enable the extra shader units or is it impossible using software?
Here in europe it's the died for find an HR03GT :(
I tried along with few others. The flash works but there is a problem with the drivers. First I had to modify the .inf file to install them and then it crashes as soon as I start ATItool. I checked with rivatuner and although it said 8800 GTS 512, it stated only 112 SP :(Quote:

Apps like gpg-z and rivatuner, I wonder if they hardcode the display of SPs based on the chip id that is read from the bios.
trry the new drivers that were released today and report backQuote:

Just tried yesterday with 169.21 still the same. But I have something weird. After I flash the card, I can't install the drivers because it said that my card is not recognize.Quote:

So what I do is I edit the .inf and replace 0600 by 0610. after that it installed but I'm not sure if it really works or not.
When I did that with 169.06, it only froze when I started ATI tool but now with 169.21 it freezes even on the Desktop after ~1 min :mad:
Anyone knows what is this device id and why windows shows a different id from nibitor ?
EDIT: The flash was made with the XFX 8800 GTS 512 bios. You can find it on mvktech.net. My first attempt was with NVIDIA bios and I had the same problem.
What are the advantages of flashing the 8800GT with te 8800GTS BIOS?
I think the idea is to unlock the extra stream processors on the G92 core. The 8800GT has 112 out of 128 enabled.
if the stream processoirs are illed to laser it's impossible to re actif them...
we still have not established whether the SP's are physically disabled or not.
If you think about it, the 8800GTS320 was A1, the 8800GTS640 with more SPs was an A2 chip.
Both of these GTs are A2 revisions so there is a chance.
in fact we don't know if the stream are killed physically... But nobody who's flash the GT with GTS bios are activate the 128Stream :(
There may be some form of software (driver) protection that we dont know about.
All the gpu's have at least 128sp's made. So what happens if you try to activate a SP that is defective? You get checkerboard effect. But that's not waht we're seeing here.
they are laser cut.Quote:

I have a twintech 8800gt, and I tried the 8800gts bios mentioned some pages before and today the gigabyte 8800gts bios from mvktech.net. The bios flash was successfull and then you need to install the 8800 gts 512 driver from nvidia drivers manually(I used 169.21). When I restart the system freeze or the cursor moves slowly in desktop and I have ARTIFACTS. This mean the extra shaders are ENABLED, but there are some kind of protection(software or hardware) or the extra shaders are faulty. I remember when we tried to do the same with the radeon 9500 @ 9700, the extra pipelines was enabled but if there was faulty you had artifacts, but the system was'nt freeze, you could run benchmarks with artifacts or without if you had a not faulty core.
The freeze is because of the protection or the laser cut I think so maybe the extra shaders are not faulty, we need a way to remove the protection or connect the cut if possible.
People have both GT and GTS can look carefully arount the core to see if some electrical trace are cut in GT?
Here is a photo of the artifacts.

That is very interesting soki, keep us updated.

Are the engineers at Nvidia prohibited from talking about this due to NDA?
im pretty sure the shaders are laser cut, if somehow we can unlock them, the 8800GT will go down as the best GPU ever created, as far as all around price/performance/modability............so far i love mine......cant ask or anything more for $270
We´ll have to wait if somebody else is going to flash GT with GTS bios.
Ok, I have just flashed my sparkle card with the Gigabyte GTS bios from MVK tech and its gone fine. I did change the clocks to stock GT clocks first with Nbitor.
I had to change the Device ID in the drivers to get them to install.
And it looks like it made no difference, the extra processing pipes seem to still be locked.
http://horrorwood.googlepages.com/GTS2.JPG
I did leave the GTS volts as they were, so I will try overclocking now :)
What is the default voltage of the 8800GTS bios? Even if the SPs don't get enabled, if I can flash without problems just for the extra voltage, I'd do it.
1.15v
But I have no DMM to test if that is what the card is getting.
I am going to try to get the bios to work so you do not have to mod the drivers, if I can then I will post it.
so what if you adjust the memory timing to match the GT timings and clocks, try that?
