Heres a easy way i made up so i could flash my bios as easy as i could

RECOVERY FROM A BAD BIOS FLASH VERY RARE
Please note if a bios flash goes wrong your card always can be recovered steps bellow
1.you need a back up card and a motherboard with more than 1 PCI-E slot
2.place your back up card into slot 1 and the other with the bad flash into slot 2
3.rerun NVTubroFlash and it will ask you to flash the 1st card 1st then the 2nd just skip the 1st and reflash the 2nd
Thats how easy it is to recover from a bad flash.

what do you mean i've forgot to add that flashing your card to a BIOS?? and yes it probably does void the warranty if your card dies because of the flash but theres no harm in updating your card to a newer bios that was made for it, i updated my GTX280 from 62.00.0E.00.02 to 62.00.1C.00.80

i flashed mine with an original evga bios off a newer card

lol im just not getting it i now it voids the warranty and i know if my card did die it would cost me haft of whats its worth to send it back so i dont really care

yes i under stand that, like i said i got the newer bios from and evga 280 sc using GPUZ and flash it on to my card so the bios matched on both cards

even if my card died from other cause after flashing the bios i still think evga would replace it , but i've had this card from lunch of it and its still going strong

So you save the old bios & reflash it for RMA....

the main point is if your card dies and you cant flash it back to RMA it your screwed

loveordie

lol i dont think bios have a part numbers

 
Yes, in a way they do.  The software equivalent of a part number is a version.

& reflash it for RMA....

 
Yes, you can do that.  But that is immoral and illegal.  Technically, the warranty is void if you flash the card to a BIOS version which was not supplied with the card initially or not provided by EVGA with specific instructions for its use.

well i dont think my cards are going to need to be rma'ed any time soon and if they do ill just buy a new one, but why make newer bios's for cards and not release it to the public it must fix or change some thing or why bother doing it.

Warranty dilemmas aside, backup, backup, backup! ALWAYS backup your original read. I have seen many attempt, fail and have a $500 brick because they did not backup. Most are usually because of a very uncommon card with non matching ID strings. Be very careful and disable any overclocking software before doing the flash.

the main reason people want to reflash their gfx card bios is to get faster speeds out of them..

so you void the warranty to do something precision of afterburner will do and wont void the warranty in the process? 

is it really THAT imprtant that the voiding your warranty to get the bios versions of your graphics cards to match if they didnt before if faster clock speeds isnt the goal?

g/l to you if and when you brick your card cause guess what tech support will tell you youre SOL cause you just had to be a little twerp and went of and voided your warranty when you decided to modify the card w/o their say so..  and you can throw that 200+ bucks right in the toilet cause you basically just wiped your butt with it. 
 
 
trust me when i say.. DO NOT VOID YOUR WARRANTY BY FLASHING YOUR GFX CARD BIOS.. if your card dies (i had one that did) they WILL NOT fix or replace it.   if you want faster clock speeds use precision or afterburner.. its faster safer and guess what else.. it wont void your warranty..  why?  cause EVGA promotes Precision on their site..

Uh fellows, he's already stated repeatedly he knows the consequences and doesn't care. Kinds silly to keep on keeping on about it.

i didnt post for his benefit but to warn others not to be a total tool as well.
