In the 295x2, your running 1100 clock, 1500 mem and how about power limit? I have same card and getting 290ish.
0%. Haven't touched power limit. I use TRIXX to overclock. This is on Win7 x64 Ultimate, Crimson 16.10.1 if that helps. Temps are 70C and 67C, ambient 26C.
Maybe your card is throttling? How's your temps?
Temps not an issue, with ETH I was at 71-72, with ZEC its much better at 59-63. throttle does not kick in till 74. Same win7x64 ultimate, same 16.10.1. Using the default AMD setting to OC. What CPU, RAM and MB are you using? I have rigs with low-end Celeron and others with better MB's and AMD 6300 CPU. Several flavors of each
This is my work PC, not a dedicated rig. Small form factor Dell Optiplex 7010 (Ivy Bridge Q77 chipset), i7-3770 @ 3.4GHz, 2 x 4GB RAM dual channel PC3-12800 (800MHz) Kingston. It had two empty PCI-E slots, so I decided to stick two risers and run two cards (470 and 295). I might replace the 470 with another 295 if I find one, or a Fury or Nano to maximize hash. Free electricity. I power the two cards using a Corsair RM1000x on the side. I tried using a
3 way PCI-E x1 splitter to run more cards, but the PC wouldn't recognize the cards. I'm also mining the CPU using Kost's nheqminer (AVX) with 6 threads (~20 Sol/s), leaving me 2 threads for work stuff. While mining the CPU the clock boosts to 3.7GHz.
Have you played around with intensity? Maybe -i 4 could be overwhelming your setup?
