What is the power consumption of 280x (or 7970) with Lyra2RE? (w/ overclocked and w/o)
It is higher than X11, Neoscrypt, but less than scrypt.
no way, at the same clock frequency lyra cooler than X11,13,15,Neo, approximately 10 degree C. When we ran Lyra at undervolt it took less power
I measured the power consumption. With same core, different memory frequency (750/1500MHz (Lyra) vs 750/1000MHz(Neo)), but higher voltage (880mV vs 840mV) Lyra is about 10% more than Neo. 950W compared to 870W with Neo. That is with 4X7990. I cannot run Lyra with the same voltage as it is not stable.
>use different voltages for each algo
>compare results and draw a conclusion about power usage
That just means lyra requires more power to run at the same frequency.
That just means his card can't run Lyra2RE at that frequency with that voltage - the correct response is to lower the frequencies and voltages until both can be tested with the same settings. Otherwise, you've just trashed any possibility of a meaningful result.
so plz try different config to get max speed and less power, may be your problem in catalyst and OS driver version, or mem/core ratio and other setting like intensity, worksize. We tried trix,giga,ref 79xx,asus,pcs,msi and among them run stable at undervolt and high speed
