Hey guys.
I have bought 2 XR 470 4GB NITRO OC with ELPIDA memory, like the model on the title description and the photo.
I couldn't flash the sony 87 bios or others bios that i found on the net cos they are diferent from my current bios, some of the Sub ID and other stuff are different.
I also couldn't change the straps values with Polaris Bios Editor cos they are written in a non clear mode and can not be identified.
Then i found the SBRPolaris bios editor and there the straps show ok
First thing i did was copy the 1500 straps to the above, and saved the bios and then flashed it with ATI winflash. At the end of the flash process i got the msg that the flash has ended correctly but the PC frooze up. after i hard restarted, i found that i could hash with stock clocks at 25mh/s compared to 22.3mh/s with original bios.
Then i set 1100mhz on the Core and began by rising the memory clock by 10mhz every 1hour of succesful mining. I did this till i got to 1860mhz on the memory and i began getting lots of artifacts on the screen and the hashrate on the miner got to 0mh/s. I tryied to raise the core voltage but i couldn't get over 1850mhz. With this cloks i got 26.4mh/s.
Then i changed the bios and copied the 1625 straps to the above, and i got the PC freeze again when i flashed, and after the restart i found that i could hash at 23.2mh/s on stock clocks, compared to 25mh/s with 1500straps and 22.3mh/s at original bios.
Then i began OC again and still can't get over 1850mhz on the memory.
Now i want to try the 1750 straps to 2000 and try again, but i thoght that someone could help me with an already tested bios for this model i have.
Any help would be very much appriciated.
Thanks.
