Hello dude,

Allow me to congratulate you on your excellent miner and the hard work that this needs to maintain it, but I have a great doubt, I have 3 sapphire r9 280x dual-x cards with hynnix memory and I recently bought 1 card identical model exact all except The memory that is elpida, I would like to know, why if they only differ in the memory chips (they work with the same design parameters), the card that has elpida memory has a less speed than average 10,000 H/s?

Regards.

I have a similar issue like yours. I have a XFX R9 280x Black Edition that has Elpida memory and only gets 289H/s where a friend has the same setup but he has Hynix and he gets 310 out of it with lower clock settings. I am looking for someone who has a BIOS mod that might unlock that extra potential.

Hi, i have saph 280x with elpida and get 300 sol on zec 1090/1600 mem

Curious to know your other settings. What driver are you using? Windows 7/10, Linux? Power increase % at all? Undervolt/overvolt? If you can post a screenshot from GPU-Z?

Win 7/64, card on stock params but modded mem straps 1500 to 1625
