TiZoRs 8800 series overclocking/flashing guide

Ok, before we can continue, I WILL NOT BE HELD ACCOUNTABLE FOR ANY DAMAGE TO YOUR HARDWARE.

First of all you need to find your max overclock, i did this buy using rthdribl, this prog heats up the gfx card nice, found here http://www.daionet.gr.jp/~masa/rthdribl/

Run in full window mode for about half hour, dont worry about your gfx temps reaching 70+

I use rivatuner for overclocking, monitoring temps, and setting fan speeds,

I advise you run your fan speed at 80% using rivatuner, i cant hear any more fan noise at this speed but it cools better. unless you have your own cooling.

For info on core clocks, shader clocks, mem clocks see here

Now Create a bootable floppy, and install nvflash nvflash 5.50 onto the floppy.

Reboot your computer, enter the bios to make sure you set floppy to boot first.

After the floppy has loaded, you will see A:> type nvflash -b 8800BACKUP.rom make sure you add .rom or it wont work.

Few lines of text will apear, and saving bios successful.

Enter windows and download this.. NiBiTor v3.5.

Open this then load the bios from the floppy, then you can set your max overclocks in within this prog, save the bios as 8800OC.rom, agian make sure you type .rom, and make sure you have a green light for integrity.

Restart your computer and load up floppy agian, at the A:> screen type nvflash -5 -6 8800OC.rom, this will reflash the bios with the overclocked settings, reboot the computer.

If all is well you will have a hardware overclocked 8800.

ATI tool does the same thing in softwareware, am i missing something or is there no point flashing the GFX Bios unless you can up the voltages (as this is what limits the 8800gtx cards OCing potential)

willhub · 15 Sep 2007 at 13:58

Yea there is totally no point at all in risking your card for this, since you can set Riviatuner to automatically load your overclock on startup, and if the card ever breaks you havent voided the warranty too by using Riviatuner.

I flashed the Bios on my 9800 pro with an XT bios as this allowed for higher clocks so i could see a reason for it.
Also, does this hardware OC allow the card core speed to drop during 2D use as it does in ATI tool.

The 9800XT bios must have had some other enhancments like votages etc..

the 8800 series dont have 2D clocks, 3D all around.

XT Bios slackened the VRam timings as well. ATI tool allows me to set different idle/2D/3D core speeds (mem speed is constant), you can see it change when you click for the fuzzy cube to appear!

reason i flashed is cus i was sick of vista asking to enable the overclock everytime windows loaded up, this sorted that, you can always reflash to original bios for warranty.

this guide was posted as a few people emailed me on how to flash their card, since i put my overclocked 8800 up for sale.

Its a guide to people, take it or leave it, why **** it off...?

Very true. I think people can make their own minds up if they want this or not. Negative and personal comments should be kept to yourself as this guy has done this guide for the people who WANT this.

Totally agreed.

Oh, and nice guide TiZoR, clear and concise.

Jleo · 15 Sep 2007 at 18:00

Well done TiZoR, straight to the point.

I flashed my Nvidia 7900GT 3 months ago to and overclock that I know it can cope with using NiBiTor to create the bios, backed up orig.* for safe keeping and flashed my newly created bios and said goodbye to all Gpu overclocking apps to my next new graphic card arrives.

Very handy app and guide

I thought it did? You can set them in Rivatuner and ATItool anyway and they work

Don't justify your guide mate.

Its a nice instruction set for people if they want to do it.

I flashed my 9800 Pro and it was guides like this that helped.

Cheers mate

I dont think there is anything wrong with saying what I think :rolleyes:

The OP goes to the trouble of posting a guide to flashing and you say there is no point.

Why post then?

There was a point to the OP or he wouldn't have done it.

Was there no point in hundreds of people flsahing their 9800 PROS to XT's either ,that had R360 cores?

Look, I said what I thought, nothing wrong with it, if other people disagree, then fine, if everyone kept there thought to there self the world would be a very quiet place, there would never be any debates or anything.

Well, I dont see the point of flashing it just so you keep the overclock, I dont see why it's worth the risk when you can get Riviatuner to manually load up the overclock on startup...

The part that is pointless in this I think, is flashing the GTX just so you keep the overclock, now I do see the point of flashing from say a Gainward Bios to an EVGA bios, there could be other enhancments, not just overclock, it may be a usefull guide to helping people overclock, but I dont think it's worth risking the card and voiding the warranty by flashing the bios with a bios that only changes the core clock and memory clock.

Will, there is no god damn reason to say anything at all tbfh as he's not asking anything????. So the need for a debate is??????. Work that one out?.

I can't believe that you have the cheek to come back into a thread you've crapped all over and then do it again!!.

It's just like when you done that YouTube video. In fact it's not as this is actually a lot more helpful but then it's along the same lines kind of. It's not open to debate but is there to help people if they want to use it/view it/read it. You coming in and telling us that you disagree with this is just a waste of a post as nobody cares if you hate it or love it. Use it if you like it and thank TiZoR. If you don't use it then don't post as there's nothing that needs answered, is there?????. What's the need in bringing opinions into an "Use at your own discretion" guide thread?.

Follow it if you want or need to use it!. Nobody cares or wants to know if you think it's a bad idea, you just do what you do with your PC as we all have our own opinions.

I hear you mention that "You're just saying what you thought". I can't remember you ever once saying to TiZoR about it being a good and helpful guide but you find using it your way is a lot easier for you. You were just blunt and pretty cheeky imho.

TiZoR, well done on the thread

. A great guide and nice to have on the boards

TiZoR, well done on the thread . A great guide and nice to have on the boards .

As I said, I am saying what I thought, I thought it was pointless flashing a GTX just to maintain overclock when you can use riviatuner.

It's ok when other people make posts like me in other threads and they dont get flamed, I've done nothing wrong, if you dont like what I say, then tough luck, you're yet another one who things everyone should keep there opinions to themselves, if everyone just voiced good opinions the world would be a boring place. I think this guide may be usefull in helping people flash there bios, but I think the point in just flasing it to maintain the overclock which can also be achives in software is pointless, you seem to have a problem with me over nothing, I guess you dont like people saying what they think, but I am not going to stop saying what I think for someone like you...

Did I say he was asking anything? Did I post as if I was answering a question? NO, you havent had a go at anyone else who thought it was pointless have you.., oh, it's just because I thought I'd stand up for what I wrote..

What I think is, you're just stressy and dont like people voicing there opinions which may not agree with the op/you, so you start a bloody flame war, great thing that for forums :\...

Will. I wouldn't have said anything if you had wrote that in the first place. Now you are on the ball with the way you have worded it

. There just was no point in just putting down TiZor's effort to help the people who are interested in this. I don't think that's really fair now, is it?. Your first post didn't say "nice guide but I prefer to do it my own way" and wrote your explanation instead of just saying "Nah, it's pointless" in other words.

If you look at my first post, it was directed to the both of you as I've not quoted any of your posts. It was only after I seen you keep on about it that I singled you out. Trust me, I have no problem with you what so ever. Neither do I have with anyone I get into a debate with as I can't stay mad at a name

. Life isn't permanent you know.

but I am not going to stop saying what I think for someone like you...

I never expected you to. I've already said what I got involved for.

willhub · 16 Sep 2007 at 11:35

Ok, first off, sorry if I ****** you off, I'm not trying to get on the abd sides of people.

I was posting in reply to the guy above, I should have used quotes, I was not trying to put down his effort, just what I think, I was not trying to spread it all about, I understand it may help other people, but I seen no reason in thinking the part about flashing it just to keep your overclocks so you dont need to use riviatuner or anything is pointless, if the card breaks in the warranty period, then you would have to buy a new card, would not matter much if you were planning to upgrade like, but still, I am not saying flashing is pointless, I was considering flashing my 8800GTS when I had it.
