I found the hacked Modified Memory Strap does not affect the ZCash mining with the V8. It did with V7.

The hex are identical but why cant the stock 1150/1600 1.256V on toxic reach 220sol/s. (@ 201 -207sol/s only) I settled at 1010/1375 at 1.018V hashing at 195sol/s. Same memory type? Yes both hynix H5GQ2H24AFR do have someone straps for the Elpida Memory (Sapphire R9 280x Toxic) |

Bit late to the game but thinking to build a cheap rig with 280x and 7970s. $80~$100 bucks a piece locally. Worth it? Reckon I can build a 6 card rig for $1000-ish and with 1.2~1.3kSol ROI in roughly 3 months at current ZEC price. I have free electricity. I could go for 290x but they go for ~$150 a piece second hand around here. Thoughts?

I didn't understand if we are able to mod the straps on Hawaii 390. Does someone have experience with it ?

Are they stable? whats your clock settings and voltage on 280x? I lowered the TDP and powertune on mine to be stable, 20 sols less than yours. |

Maybe you undervolt too much. I run mine at around 1 H/s per 1 Watt or so. Don't care about efficiency at the moment.
