Hey guys I know a few people have tried this but I haven't as yet

I would like to know the proceedure for flashing the bios on my 7800gtx also how to make a backup of my original bios ??

I think a guide would be very helpful for all oh yeah and I dont have a floppy so if it can be done without please post the steps for that too

Cheers :D
 
I tried to do it without a floppy drive - it might be able to do but I could not.

I use a program called SLI flash to change the BIOS - it's menu driven so is quite easy. The only problem I found was that most of the time I have to remove the top card (put DVI cable in bottom card) - flash the bottom card (selecting flash SLI from menu) - replace the top card (and DVI to top) and repeat tthe sli flash procedure.

It's a great tool to use - all you need to do is copy the BIOs you want to use into the root directroy of the floppy and away you go.

This link for program which u need to unzip to a bootable floppy:

This is the BIOS I use which has served me so well, there is a tweaked memory one too, but it's experimental so I wont share unless you understand the risks involved and that the ownus is on you.
 
Tell me what you want - I'll use NIBITOR to adjust that BIOS with clocks to suit.

By the way if you are still coooling on air - if you remove the plastic cover, it improves the cooling substantially.

Is that with another fan over the heatsink, or just using the stock cooler fan? :) From looking at it, it seems that to remove the plastic cover would stop the airflow from the fan across the fins, but I`ve never tried it (yet) so cant say for sure. :)
 
Talking of temps, my BFG 7800 GTX OC never goes above 42c under load, thats was 2 hours or so fo BF2.

Maybe it's the dif revision of the cooler i have which is massive.

I'll post pics this weekend, when i can work out how to turn the flash off.
 
It is possible to flash from a cd - just make a boot cd instead of a boot floppy - I can MSN you the files from the boot disk and just add them to a bootable CD in Nero or w/e.

I could never get a NERO boot disk to load up - tried it a few times and it did not work - which is why I said it could as perhaps I done somehting wrong and CBA to percevere - it was easier to load up new BIOS's on floppy to - plus the floppy using sli flash backs up the original BIOS for ya and it all automatic just press the desired option and away you go.

I'm sure you could still use SLi flash on a boot cd if it's a dos based app. I've never used a boot cd but I know it can be done that way.

I thought that but I think it causes many more problems than it solves - trying to use a nero boot disk is bad enough :D

Well it's better than having to go out and BUY a floppy drive if you don't have one (:p) so it's just as well that it's possible.
 
mmmm £4.99 for drive and £1.99 for 10x floppies with fully automated BIOS back-up and BIOS flashing - you can't back up on CD FYI.

Plus the hassle I had in terms of man hours alone would have cost £45 just to find I couldn't (or was not competent enough to) do it usign Nero

Sound investment for hassle free flashing at a price thats right.

I'm just saying it's more hassle to go out and buy it. You don't have to backup from DOS you could just use ATiTool or something similar in Windows. So for someone who has Nero and some blank CDs but no floppy drive I'm just saying it requires less movement (though may not be easier) and it's faster and cheaper.
 
Right, well... I've messed about with this GTX/512 with stock cooling and voltage for long enough now, it's been a bit rough re-learning the ways of the green beast I must admit.

Anyways, I'm seeing max load temps of about 60c on the core and I suspect that that leaves me a little bit of temperature headroom so I could perhaps try upping the volts a tad.

I've had a quick look at nibitor and it looks a bit complicated for a simple chap like me. Do you good folks know of any good guides to using nibitor? and also what tools would you recommended for flashing the bios? I really want to get the whole nvidia bios editing/flashing thing down before I get my second card and water cooling set up in the new year. Any advice and tips appreciated.

JAFFA - you are right it appears that at 60degrees you have 10-15 degrees to play with which perhaps will give you better closk using more volts (if nibitor allows it on 512 unit?).

What are you using to overclock now - If it's rivatuner are you forcing the clocks by disabling the clock test (found in power user tab)? If you are then it could be time to get the volts changed on the GTX.

If not keep pushing the clocks until artifacts appear when u bench - these are okay for benching but not good for prolonged periods of time.

check out www.mvktech.net for BIOS and Nibitior stuff - I always use SLI flas though (works on single cards too) as its an automated process and relatively painless to use.

I'm sure I'm just doing something a bit wrong, but I can't get the clock test to disable for love nor money with rivatuner, I've tried ticking the 'disable internal clock test' and adding a '1' as the value but it still demands to run the test. Is this the right setting?



I did find a semi-workaround, by using systool to set clocks as it applies the clocks independantly of the official Nvidia clocking utility thus bypassing the clock test. It's a handy bit of software actually, It's a bit like clockgen, a64 tweaker, a GPU clocker and Sandra all rolled into one.

Thanks for the nibitor links to follow up on there Mav, better get the kettle on I have lots of reading to do! :O

Cheers,
