Overclocked V2 blade all 'O', at 16300+ but only 29% efficiency - any ideas?

Hi All, Any ideas why my blade is running at 29% efficiency?
I bought the overclock kit, all went well, all the asic chips lit up as active

Damn does it get hot though! I got a couple of fans keeping it cool but I don't think the missus is gona like the noise, I don't want to be put in the shed.

Im disappointed that the heatsink itself doesn't get warm but the ones I stuck to the topside of chips get hot. Whats the deal with that?

Anyway, advice would thankfully received. Im running one blade on a 250W DELL psu. Surely its enough for one blade? If it wasn't wouldn't I get 'X' on asic chips

Thanks thanks thanks thank and thanks again. I need to sleep now for a couple of hours - its another 4AM Bitcoin balls up

zzzzz

Ha that's exactly where I have mine in the shed and during this cold season 95% efficiency give or take a few every day.

I don't mean to bump an old thread but how did you overclock it to over 16gh/s? I have a few running at 14.5-15gh/s but didn't know they were capable of your speeds.

What difficulty pool does it mine too? Efficiency (in the software the blades have) is calculated by percentage of shares accepted. Basically:

29% efficiency = 100 difficulty 1 shares but only 29 where accepted by pool, proxy, ect. If you use a getwork proxy like BFGminer, you should see ~99% efficiency. Blades ONLY do

getwork. Use a stratum proxy. Wink

What he said. I had the same problem connecting to a stratum with the blade by default. didn't realize it for a few days, then setup a local stratum proxy and bam... 100+ efficiency.

Pick and place? I need more coffee.
