rit i got a ganiwrd golden sample 260 and it has the problem with the 2d clocks staying at 625mhz and i dnt know how really to flash the bios to fix it and i wana make sure what i am goign to do is rit before i attapmt aything
 
Don't Gainward have a tool to help you easily flash a BIOS in Windows?

If not you'll need to download something called nvflash, put the files on a DOS boot disk along with the BIOS file and then type nvflash xxx.bin to flash it.

How have you sussed modding the bios will help you? I have read this problem with the card not downclocking when in 2D mode is a driver related bug.
 
i got told to in another of these thread and i gotta get used to this new keyboard it has a built in hand rest which is getting in the way of my typing and also it is laptop style my old one wasnt gotta get used to that aswell
 
i looked into this myself at one stage....i came to the conclusion for the small gain that you make and the high risk that you take it simply is not worth it unless you have decent water cooling...even then its still a risk you take in bricking your gpu...i woudlnt bother if i was you but its up to you;)
 
Go to the thread where you got the idea from - the required BIOS files are linked with instructions on how to perform the flashing procedure by the OP, and I have written a bit of info about how to flash from a USB Flash Drive. It's not difficult :)
 
Well it can kill your card, but only in the same way that flashing your mobo's BIOS can kill your mobo.

If anything however, flashing a motherboard's BIOS is more dangerous because if you break that you usually need a replacement BIOS chip, or you have to send the board away to be re-programmed.

If you mess up a GPU flash, you can pop a working card in to be the primary display output, and stick the broken card into the secondary slot, easily reflashing the broken card's BIOS.

Or you can even blind-flash if you don't have a second video card/second slot (although it's a right pain).

If you have the right bios file and your power doesn't cut off whilst flashing, it's pretty safe.
 
I think its worth repeating my earlier post. The problem you seem to be describing is that your card remains at the high core frequency setting it should normally only use in a 3D game when you drop out to desktop, i.e. it does not return to 2D power saving clocks, which I think by default are 300MHz for the core. From what you say you seem to think flashing your bios will fix this. You seem to say someone told you this in another thread. I don't know if the advice given was specific to the Gainward card you have but I can tell you, from my own recent research into this very problem, that the issue with a card getting stuck on 3D clocks is very likely a driver bug at the moment, which seems to affect Vista users especially. The problem is that several supposed non 3D programmes can make the driver think it should switch to 3D speeds. There is also talk of this possibly being related to what PCIe frequency you set in the bios. If it is the same problem I am thinking it is then flashing the bios won't make any difference and the problem will remain. Can you point out the therad where you were told to do this?

A bit more info, when I was testing my gtx280 in a windows xp machine, I noticed than with 2D power saving clocks (300 MHz) the VRMs were taking about 2A. Now on Vista 64, with the card stuck in 3D performance clocks (750 MHz), on the desktop without anything running it uses 12A. Starting a 3D game this shoots up to over 40A.

yeh i can it is this http://forums.overclockers.co.uk/showthread.php?p=13893624#post13893624
also ive updated my drivers to try and fiz it that was the first thing i did and that hasnt worked either i know have flashed my bios and rivatuner says it running at 626.40 core clock when doing nothign and so i have no clue btu somehow i need to fix it as it running the life dne of the card and costing me electric

i never knew that,thanks;)
 
Reread the above by Bubo. Editing and reflashing your bios is not going to solve this problem. For one thing, a bios is complicated. Someone unsure of how to flash it stands a slim chance of heavily rewriting it, most bios editing is changing the clock speeds and leaving everything else alone.

Second, typing commands at a dos prompt can be very sensitive to typos. Your posts are somewhat riddled with these. As such, I do not recommend any process which is heavily dependent on you not putting a single letter wrong.

If it is a driver issue, which it does sound like, and the latest driver does not fix it, then be patient and wait for the next driver.
 
It took me a while to deocde post #15 but I think he is saying he has already flashed it, and found it didn't make any difference.
 
SORRY about all the ****ty typos and stuff getting used to laptop style keyboards they are a lot more sensitive then what i was used to and above is correct i have flashed it with new bios and that didnt work and i updated drivers to newest ones that also did not work what else could it be?
and is my typing better now?
