Well, my Jalapenos have shipped (honestly thought I'd never see the day) and was wondering how many people are solo mining with their units. Currently an upgraded Jalapeno will take about half a year for 25 bitcoins, at the current level of difficulty. Realistically it could be years before a single block is hit, and quite possibly never. Risky proposition when one considers the unit may never pay for itself with solo mining.

Solo mining with 5-7GH/s? Seriously guys, what are you smoking?

This is not a clever experiment to moove object from cooler to hotter place, it can create condensation, which can lead to shorts and damaged unit.

i agree, you might regret the ~5% extra later ...

alternative method
sell house
buy new house in Antarctica
run rigs at even cooler temps -40

only downside you will have to buy a very long fibre optic cable XD

How often do you solve a block? Just curious. It seems like statistically, with so many people mining and a block being solved only every 10 minutes that a lot of people would never get a block reward.

At my Jalapeno hashrate, generation time for a solo block is 62 days and 20 hours according to http://www.bitcoinx.com/profit/

is that what you were referring to?

Not really. I'm just wondering if you have ever actually received a block reward and how long it took to get it.

No problem - I have not received a block reward yet but Im on a pool.
I am choosing to mine on a pool for now, so if I do find one, I wont see any individual benefit.
I did try going solo last year for a few weeks with 3 GPUs but found it too frustrating, and to be honest I couldnt actually determine if it was working so went back to pools.

but anyhow:

TL;DR summary: chill the Jalapeno for 15 mins prior to powering it up and see if you get a 5% bonus

(DISCLAIMER Just in case:be aware of condensation if your location is hot/humid - I wouldnt recommend to power it up if you see water beading )

Solo mining, no change in total network hash rate, 20 hours a day for 62 days, then you have what percentage of finding a block??

Give it a liquid nitrogen dip, it will start hashing at THashes.

LOL - more likely will just shatter the ASIC with the -200° delta T

So I received my second Jalapeno today and started it hashing immediately at 7.45 GH/s

Went home, put it in the freezer for 15 minutes while I set up power supply, made room etc.

(took it out of the freezer first)
Powered it up and it is now hashing on average at 7.75GH/s

so my results so far on the two I have received:

Jalapeno 1: Original average: 7.2 GH/s, After chill and power cycle, 7.63 GH/s Improvement = 6%
Jalapeno 2: Original average: 7.45 GH/s, After chill and power cycle, 7.75 GH/s Improvement = 4 %

anyhow, I'm enjoying the extra 730MH/s
