      Hi all, after almost a year of mining realised I should have flashed these for better performance and lower power!

      Looking to do this tonight, how do I see the current bios can I see in windows or on the cards or is only way using the flash software on USB in dos mode?

      Also when flashing should I take out the other 2 cards or can I flash all 3 in one go?

      Thanks all

        Thanks there’s a switch on them I can see so if you move that if anything goes wrong flicking it back should mean we all good?

        Will give it a blast on one to test, I think it disables the hd I but VGA is fine.

          Thanks all looking good, worked first time so did them all.

          Gone from 590 to 646 so far on each which is nice as they cooler too :D

          As I use GUI miner and afterburner I’m using 1420 clock and 1100 which is max on afterburner but read using 1155 is way to go.

          I also see people use other flags or so but they all combiner configs which I don’t have clue about ;<

          Can’t believe not done it months ago lol, flashing sounded scary

                  f43 are the way to go they change voltage down to 0.975 also so should be saving bit of power per card from the stock 1.25 they were. Fans now running lower too.

                  Average 1.986mh/s
                  Roughly 660 per card from 590 using old bios and GUI miner.

                  Cgminer took abit to work downloaded loads of different versions, in the end used the cgminer I already had in GUI miner folder and works a treat, there are quite a few stats on there so not 100% sure all is as should but will post screen shot later.

                  Followed article on rumorscity website if anyone else is interested, google flash bios 7950 litecoin and will be first result.

                      So finally got my power usage plug and abit surprised, it’s showing average 940w on my 850 corsair psu hmmm zit has been running stable should I lower gpu clock and mem?

                      Also it has a cost part 00.00 where I put my 12.04 per kW price not sure if it should be 00.12 or 12.04 confusing. ???

                      Any idea on cost per day on that price per unit?

                      Thanks

                        Feather calculator showing 1.92$ and ukpower.co.uk showing 2.75£ ???

                        Forgot to change wattage :) that’s correct @ 2.75 Gbp perday.

                        Is it safe on my psu running 100w over it’s rated ?

                              F43 is the way to go with these cards. :)
