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

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.

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.

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.

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.
