And here they are:



My DOA/Reject rate instantly climbed from less than 2% to over 18% with the addition of your S4 before you switched it off prematurely 

It would have been a more accurate test of your S4 with p2pool if you had kept it running for the full 10 minutes - but as we can clearly see by the graph, the S4 does not work efficiently with p2pool, as you wrongly stated earlier with your 1 minute screen. It also didn't get anywhere near 2Th.

I was under the impression that Bitmain was doing some major development with their hardware & it's problem with p2pool - but this miner seems to be a bigger version of the poorly performing S2 with p2pool I'm afraid.

Can you tell me what settings you were using in cgminer?

IYF.
