Hi guys Ive searched on this forum, and I dont think ive found the right firmware... I bought 2 sapphire extreme 5830s from newegg. the Max I was able to get was 900MHZ, now I wanted to go with 1,000MHZ but i couldnt it said it was locked. I tried every firmware I could find and ended up nuking the cards *ie they display nothing flashed wrong firmware* So I got my money back and bought the same cards else where for $40+ cheaper

win win... So now im pushing stock and 2 cards is yielding 467 Hash... The cooling i have a stock fan a thermaltake case v4 and some fans for the gpu the coolest ive seen this thing if i remember is 60 - 65C during the day it runs a nice 70c - 74c some cases ive seen it go up to 84c.

Probably will not be able to get 1000mhz I have 9 of them cards and tried almost every combination possible of BIOSs I edited using the RBE on windows then flashed to them. The best I can get out of them is using a single card in a machine then it will do 1000mhz, 300mhz memory if I try putting two 1000mhz cards in the one machine then they will lock up within seconds. Now running them at the 900,300 combo they run forever at them speeds get 291mh/s out of those and the one card I have at 1000 mhz 317mh/s. I'm using Ubuntu 11.04 for the OS on all miners. For the temps most I ever seen during this past summer was low to mid 80s now it is cooling off with fall coming on they are low 70s with the odd high 60s depends where the card is located on the boards. In short if you have access to windows machine then get the Radeon BIOS Editor get the BIOS off the cards then edit it to the 900,300 combo flash them with it and you should be good to go.

OMG Thank you! and ovidiusoft and Bkkcoins the 3 more important and influentual advice here. ok so my response to you is I am on the same freakin boat.. My next step was exactly to do that. Use RBE on a windows box and also dump the bios just incase, like last time I bought 2 cards from newegg we flashed it with the wrong bios and could not find the original bios ***ANYWHERE*** so in the end it went back to newegg :-) and alas I found 2 extremes that someone bought from newegg. Now I dont know if im shooting in the dark but I can find the part # off the box and hopefully that tells us what this card can take?

@ Ovidiusoft

this is what happened when I enter your commands.
