Hi,
I just bought two Sapphire HD 7950 and its kinda weird, but I'm having 14 mh/s. It seems okay for this card, but what I find weird is that sometime the card is going up to 20 mh/s when I'm mining its been 1 hours or more and sometime it is going down again at 14 mhs... I use Claymore dual miner 7.0 with siacoin mining at default intensity, I've tried ethereum only mining, but it dose not change the speed more than 300 kh/s. Is that normal ? My other card usually don't do this and the temperature is stable. Both of them are plugged in to the pci express x16 directy and I have 12gb of ram with an Intel core I7 960. My PSU is a 750 watt EVGA Bronze. I've tried to overclock it slightly to see what is going on, but it didn't change that much...
Thanks.
