I have the same cards, also Elpida memory, and i’ve been struggling to get them do more than 25MH/s.
I’ve been running them with the same overclocks on both cards, so i might actually be limiting the better one because of that. ASIC quality on 1gpu is 63.5% and the other 68.2% according to GPU-Z.
I’m currently doing 1075/2000 with -96mV via MSI AB @24.65MH/s each. Wattage i’m not exactly sure, AB reports 75watt, so probably around 100 each, and around 63-67 degrees Celsius most of the time.
I’ve been trying some things with memory, tried copying the 1:1500 up but that basicly halved my speeds. I put those back to default. I did copy 2:1500 up and since then i’ve gone from stock 20ish to 24ish. In my latest mod i only copied the 2:1750 to 2:2000, this got me another MH/s. I can do exactly 25MH/s with this, but then i’d have the core up at 1300 or 1350 or so, it’s not worth the extra power use (electricity here is 0,22USD/kwh ). I expected more from these cards.

I’ve been struggling to understand the undervolting via Claymore’s parameters for both core and mem. Tried changing those and had an instant BSOD If you or anyone else for that matter has advice on that would also be great.
