What do you guys mine with the Elpida memory ones?
ZEC seems to hang the system even at stock settings.
ETH is good at 29mh/s but very difficult to undervolt and maintain stability.
R9 290 is a ton better at ETH than ZEC - bios mod them with one of TheStilt undervolt bios helps a ton on dropping temps, stability, and lowering power usage.
1100 core is WAY overkill for ETH mining on them - 900-950 seems to be about the most you need for max hashrate AND drops power consumption quite a bit.
Might vary a bit if you have aftermarket cards - mine are Sapphire reference models, and seem to be optimal on ETH mining at 1250 memory clock (1300 LOWERS hashrate and much higher gets unstable).
Will do more testing this weekend. But 1100 core is not overkill, r9 290 is core bottlenecked not memory limited in my testing. But I may be wrong, will need to try Stilt bios mods
I forgot to post, but sometime back a mobo capacitor popped and killed a card.

The whole system was still hashing (for 2 whole weeks) except for this card when I flew back to check.
