  • Hadrien Ultimate Gaming

    Hi I have an rx480 4gb (sapphire rx480 nitro oc +)model and i wanted to flash i checked on my box and scratched the label to see if it was 8gb. It was , only problem is that I have a hynix memory and not samsung memory so i dont know if flashing will break my card even though my card is a 8gb model.Thanks for reading this hope you or someone can answer as fast as possible.

  • Mocanu Bogdan

  • Maverick Winter

  • Fernando Ribeiro

    Hi There!Thanks for your videos, they are very helpful. I have a question though, since I feel that I still didn't get a stable and ideal combination of memory clock and core clock. My gpu's are MSI rx 570 x gaming 4Gb, Hynix memories. On afterburner I have 1050Mhz for core clock and 2025 Mhz for memory clock. I'm getting about 28 Mh on ETH + 3900 Mh on DCR on Claymore miner. But it doesn't seem very stable, because after a couple of hours I tend to have one random GPU that decreases to 25 Mh or less. Do you (or someone who read this and has the same cards and memories) have some values to compare with these?

  • 林曈

    Thanks for this nice video. I tried this method to modify the timing strap of the memory (RX480 8GB Hynix), however, each time I flash the bios, the system couldn't recognize the card and cannot use it for mining. I have to restore the back up file and everything is working only at 22 MH/s. What is going wrong? I feel very flustrated. Appreciate any help.

  • Mark Rex

    Link to hynix_mod.html not working

  • JD recycling

    So i did this on a MSI armor rx 470 8gb and i got 18MH in ethos, also for my timings i have a 2200 option when in here i only see a 2000, do i also change the 2200?
