![]() Guide to mod your 6800GS AGP to an Ultra Extreme! -------------------------------------------------------- Finally! A complete guide about how to mod your 6800GS AGP to a legitimate 6800 Ultra Extreme! Remember that this tutorial is only valid to AGP versions of GS because PCI-E versions uses a diferent core, that don't even have the extras pipes. Well, it's impossible to enable what you don't have... ![]() !! THIS TUTORIAL HAVE EXPERIMENTAL AND EDUCATIVE CHARACTER. MAKE BY YOUR OWN RISKS ONLY !! Enought bull****s, let's go to business, =D. I've used an eVGA 6800GS AGP with Part Number: 256-A8-N387-TX. First, download and install the last version of RivaTuner, actual is v2.0 RC 15.8. DOWNLOAD RIVATUNER. Open the software and follow up: http://i7.photobucket.com/albums/y27...aturner_01.jpg - 6800GS AGP originally "castrated" with 12/5 pipes. Note driver version: 83.60 BETA http://i7.photobucket.com/albums/y27...aturner_04.jpg http://i7.photobucket.com/albums/y27...aturner_02.jpg - Select CUSTOM, enable "Allow enabling hardware masked units" and click on CUSTOMIZE. http://i7.photobucket.com/albums/y27...aturner_03.jpg - On "HW masked" it shows the two bastards bits that are masked. Enable it by simply clicking under arrow shows After enable the two bastards bits, click OK and you'll be asked to restart the system. Do it. Open RivaTuner again and verify if the extras pipes are enabled.If yes, still isn't time to open the champagne! I believe that you have some "hard" game installed on your machine, right? (if you don't, what the hell are u doing with a 6800?). Run the hard game and play for at least 30 minutes. Gives preference to run with the most quality you can. So, you'll be pushing your card to uses all the potential. You can scan for artifacts using the ATi Tool version 0.24 Beta 13, that are compatible with GeForces. If you don't detect any visual artifact, bug or something of type.....prepare the sallon because the party will start!!! ![]() CONGRATULATIONS, YOU JUST ACQUIRED A 6800GT!!! -> If you detect some artifact, bug or something, backup the process!!! Sit down and cry because your card have damaged pipes by factory. BUT...still have hope for you, my unlucky friend. Try to enable only PIXEL PIPE and unable the VERTEX PIPE or "vice versa". Who knows if just one of the pipes are damaged and you still can uses one of then...it really happen with some brands/models But the tutorial wasn't to mod to an Ultra Extreme you moron? Wait my child...this was only the beginning, relax because now it goes burn!!! To mod to an Ultra or Ultra Extreme will be necessary mod and update the bios of the card (wich now is a legity GT, remember?). You'll need two softwares: NiBiTor v2.7 to mod your bios and nvFlash v5.25 to update the new modded bios. Everything right under here? So let's go to next steps. Open up NiBiTor 2.7 and: http://i7.photobucket.com/albums/y27...tor_mod-01.jpg Making this, the bios that are running right now on your card will be loaded to NiBiTor, so far, posible to mod the options. Before starting modding anything, made a backup copy of the bios that was loaded: File -> Save BIOS!!! Recommend that you create an east name like: biosback.rom, biosorig.rom, biosold.rom, etc...you really can need him...Modify the options in agreement as your necessities and own will. Another time I warn that I won't be responsable for some ######## that you can do!! Make by your own business and risks, ok!? I've just modified the Core and Memory clocks to 450/1100 MHz (without enable "Change amount of active performance levels"), on Temperatures I've configured the Fanspeed 3D to 100% and on Boot Settings I've modified the text that is showed when you turn the system on (under Adv. Signon). If you want, you can enable the option that shows the amount of memory size, change the resolution, color of the text and boot during time. Are only visual "cosmetics"... After finish changing options, go to File -> Save BIOS and save with the name and where your want to. If you use Windows XP, make and boot disk by going under My Computer -> clicking with right button on Disk 3 1/2" -> Format -> MAKE A MS-DOS INITIALIZATION DISK. After create disk, extract, on same disk, the files cwsdpmi.exe, nvFlash.exe (inside nvFlash.zip that you downloaded), "biosback.rom" (original bios that you MADE backup), "biosmod.rom" ("La transformación" bios!). Copy the original bios and the modded bios by NiBiTor (called biosmod.rom) to the same disk!!! Restart system and run boot under (of course, lol). Run command: "nvflash -4 -5 -6 biosmod.rom" (without quotations marks). It will ask if you want to update bios, you anwser no...SELECT YES BROW!!! ![]() CONGRATULATIONS, YOU'VE JUST ACQUIRED A 6800 ULTRA EXTREME!!! ![]() How much did you pay for it??? Hum... ![]() Verify idle° and full° temperatures. I think that some guys will need cooler mod. Me too...here it is 56°C idle and 65-69ºC full...tense...cooler mod going run here! EDIT: Make backup of the original bios under NiBiTor BEFORE starting moding and saving after.

If you want to enable the 16/6 pipes under bios and complete abandon softmod (in case, RivaTuner), here it goes the steps: Open the file "NV40BIOSHwUnitsMaskEliminator.rts" in folder C:\Program Files\RivaTuner v2.0 RC 15.8\PatchScripts\NVIDIA\NV40BIOSHwUnitsMaskElimin tor. Select Continue -> find the "biosmod.rom" that you mod on NiBiTor v2.7 -> YES. You'll see this screen: http://i7.photobucket.com/albums/y27...-6_bios-03.jpg The "biosmod.rom" file was updated. Now, you need to re-write at the same disk that you used before. Update the file in disk, restart machine, boot up under the disk and repeat the last steps: Command: "nvflash -4 -5 -6 biosmod.rom" (without quonation marks). Restart again and...my god!!! Now you have a 6800 ULTRA EXTREME forever!!! How much did you pay for it??? AhiuHuahIUa. GOOD!!! \o/ Thats all folks! Any doubt, comment, sugetions, good or bad critical arguments, we are here. Have fun with you brand new toy that has, now, 16 pixel pipes, 6 vertex pipes, 450 e 1100 MHz natives!!!

I didn't resisted...was too excited with this excelent card and I've adapted an Athlon XP fan on my pet!!! Now it is really "FULL MODDED" version. Check the pics: http://i7.photobucket.com/albums/y27...ler-mod-01.jpg - Original card without the protector plastic. Note the excelent copper base. http://i7.photobucket.com/albums/y27...ler-mod-02.jpg - Cutting down the protector plastic to adapt the new fan http://i7.photobucket.com/albums/y27...ler-mod-03.jpg - Plastic after cut and all the material that I haven't used to mod: iron ruler, stiletto (thats broken up a little), Cooler Master fan and your copper dissipator base (that I don't have used) http://i7.photobucket.com/albums/y27...ler-mod-04.jpg - Card with the protector plastic cut http://i7.photobucket.com/albums/y27...ler-mod-05.jpg - The new pet!!! ![]()

My 6800GT runs the Ultra Extreme BIOS off an Albatron UE press card. Default 450Mhz/1100Mhz with a higher voltage. The thing I havn't seen before is this cooler mod. I must honestly say, that is very good thinking. Can you give us some before and after temps (loaded and idle)? I have a very special 60mm fan I have been saving just for a mod like this. 60mm 8000RPM Delta Electronics 1.2A fan. Now to get fitting. Very well done dude ![]()

I forget to post the temp differences: - In full stock (12/5 pipes, 350/1000 MHz and original cooler), was 50-52°C idle e 60-63°C full. - With Ultra Extreme mod (16/6 pipes, 450/1100 MHz and original cooler), was 52-54°C idle and 62-65°C full - Full modded to Ultra Extreme (pipes, MHz + coolermod), stay in 52-53°C idle and 59-61° full. I think that coolermod hangged well because it was @ultra extreme natively (definitive mod under bios). - Full modded to Ultra Extreme (pipes, MHz + coolermod) BUT with volt mod to 1.4V on core (original is 1.3V), stay in 53-56° idle and 62-66° full. I've tested the full temperatures using the "Scan Artifacts" function per one minute of ATiTool 0.25 Beta 13 software. Despite the name, it is compatible with GF's. It is notable that cooler mod hang something...But with volt mod the temps became a little hot again. I hasn't test the temps using games yet, only using Scan Artifacts at the moment. Can't get time to test with games and 3DMark's.

Do you think it would perform better if you removed the stock blower on the HSF and just used the bigger 60mm fan, allowing it to blow out both ends of the cooler? At the moment, the stock blower, and the fan are fighting eachother to some degree, causing turbulance on the left hand side. The other improvement I would make, is using a 60mm duct, with at least 1 inch standoff to space the fan off of the GPU sink without losing any air pressure. See, at this point, the center of the fan, which is about 2cm diameter is not providing any cooling, and that is near the center of the GPU's placement in the sink. Using the standoff, or better yet and angled standoff, you would get much better airflow efficiencey. Using a bent 60/80 adapter standoff, you could even mount a nice 80mm fan using the duct to it, which I think may just improve things even better.

http://www.coolpc.com.au/catalog/pro...products_id=90 http://www.coolpc.com.au/catalog/pro...products_id=91 If you used one of those, it could really improve things alot. Removing the blower would give it more exhaust room, reduce turbulance, and improve it even more. Then lastly, you should do a lap job on your heatsink. alternatively, you can take it to a jewler, and they can polish the HSF's bottom surface up to a mirror finish very cheaply. Then a good coat of Arctic silver 5 and it would be brilliant.

I'll try to switch off the original fan and see the temps running only with Cooler Master fan. If don't get any better I'll adapt the Microfins dissipator copper base that I don't used before (see in pics).
