Ok, been running over a day now no problem: Is that an experiment ? why the plastic bags ....?

Found my Jupiter hashing at 140Ghs just now (cgminer and pool), so back to 0.96 for me.

Is that an experiment ? why the plastic bags ....? to raise the temperature closer to ideal in my cold basement

I'm only getting 93-99GH/s on my Mercury Tried 0.98 tried 0.96 tried enablecores.bin on both tried different pools *sighs*

For those noticing that some of their units need to be warmer for better rates, I have no doubt about that. I have the same issue with my GPU farm of MSI TF 7950's. Some of the cards don't like being cold at all. The cooler they get, the higher the error rate and the lower the hash. The warmer, the inverse occurs.
For these cards, the sweet spot seems to be 75-82. Error rate is less than a percent, hash rate is easily 690+. Below 75 they slow down and error rate doubles or even triples.
It's the 28nm architecture.

Interesting, a chart on this page shows that 28 nm comparator sensitivity(perhaps to EMF?) drops and levels-off at the temps we've noticed working well: http://www.design-reuse.com/articles/28591/mixed-signal-ip-design-challenges-in-28-nm-and-beyond.html

And though way earlier in this thread I was dogged for not being an electrical component design engineer while making some comments on design, assembly and deployment.. every now and then, it's as if I know what I'm talking about. lol I predicted the 28nm would have issues if too cold. Looks like I'm partially right. One thing is for sure, they designed the cooling setup to work in hot datacenters, so it's no wonder some of these units aren't able to warm-up when used in houses.

I guess the crappy ones that couldn't stay cool have a new selling point...

Not all of them have the same average temperature, and the overengineering on KNC's part allows for a greater fluctuation without impacting the hash potential. Plus, some folks have lots of computing power but not adequate cooling.. so it works well. Either way.. totally called it

I think, November miner deliveries has already been shipped and they reach customers today. Customers can start hashing from tomorrow, 00:00. ack hope this is not true and they don't ship till nov 15th as they said..if not what are we looking at every 10 days a 50% difficulty increase? hard to ROI back that way! They told me they planned to have A month in between shipping, and I believe they will hold up to that, other wise they would piss off allot of customers, and anyone smart that paid with a credit card could get a refund if they wanted, and would lose allot of customers if they plan on having a gen 2, though a gen 2 would only be worth while if they got much better watt / gig performance I have heard from a forum member that his $5000 "November" order shipped on 30/10 No way

Nope. The pool "solved" the block, not him. What he did was to use a machine which generated the SHA-256 number for the pool to "solve" the block. He would only had "solved" the block if he was solo "mining", what is not the case.
