I've not tried this before with JPC, or any other staking coin, so...

I receive around 1000jpc total in staking every day for the past few weeks but it's split up in about a dozen separate transactions (eg 33jpc, 122jpc, 9jpc etc) If I use coin control to try and get the stake arriving in less transactions (hopefully 1 per day), will the new total daily amount of stake I receive be reset to a lower amount until it builds back up again? Or will it stay roughly the same as to what it was before combining?

I've not made a peltier equipped gpu or cpu cooler. Just pointing out it would be the way to go for anyone working on a super cooler.

I don't have any pics of a peltier. They're easy to find on Ebay though. It's a flat chip with 2 wires coming out of one end. They come in different sizes. For the coleman cooler, the peltier has a heat sink on each side of the chip. One side gets hot, the other gets cold.  By reversing the DC leads, you can change which side heats and which side cools.

If a person placed the cooling side of the peltier directly on a CPU or GPU, then used a heat sink on the hot side to remove the heat from the system, it should work like a charm.

Edited for spelling*

As the ice inside the gallon jug melts, there will be alot of condensation on the outside of the jug. Kinda like when you leave a glass of drink containing ice on the table for a bit. The cool temp of the vessel, cools the surrounding air near its surface to its condensation point, so condensation is deposited on the surface.

Have you ever looked into peltier coolers?  Very neat little items. Add a DC voltage to the 2 wires, one side gets hot the other gets cold. I have a coleman 12 volt cooler that works as good as any fridge. It contains 1 small peltier cooler chip with a heat sink on each side. And the way peltier coolers are made, you could sandwich one to a cpu or a gpu chip and have a supercooling system without alot of cost. The peltier devices are available on Ebay for a few bucks. That's a much better way to go IMO, it'll save you from condensation and the pain of constantly freezing ice for the ice bucket cooler.


I personally think an extra cooler for a GPU is not needed. As long as the heat sinks and cooling fans are clear of dust debris, they will run cool. Most overheating problems can be solved with some compressed air and a vacuum cleaner to remove the dust clogging the heat sinks and fan blades on the cards. I had experienced some cooling problems on my 7950's about 2 months after installation. The temps simply started rising day by day. Each day the things became more difficult to cool. They went from running 68 to 70 to running 80 and eventually 85. I had added box fans blowing directly into the open chassis on the cards, with little cooling gained. I tried lower hash settings, but that didn't help. I was about to pull my hair out.

Finally , I did a dumb thing. I couldn't physically see the fans moving because of the card's location in the chassis, so I stuck my fingers near the cooling fans on one GPU to feel if there was any air movement (to verify the fans were turning) BZZZT....I touched the fan blades by accident. When I did this a cloud of dust flew out of the fan, a few seconds later, the GPU temp dropped a few degrees. 

I pulled the cards and sure enough, they were completely clogged. I was shocked at the amount of dust that was packed into the card heat sinks and on the fan blades themselves (except the one I touched of course). A vacuum cleaner wouldn't pull it all out from between the grills in the heat sink. I had to physically remove the dust clogging some of the grills with a small eyeglass repair screwdriver. This happened over a period of 2 months!

Cooling problems = Dust in your GPU card heat sinks.

If people are interested I could make a few signatures that link to this thread like the one below for promotion of this coin on this or any forum.  Colours and wording can of course be changed, the one below is just an example.


Depending on what member level you are will also affect what you can have as a signature too.  I can make signatures depending on member level if needed.

What does --compact do/mean exactly? Does it work for x11 too, or just x13?

Finally got mine to work (better late than never)

Had a type many lines down that I couldn't see on teamviewer ! Doh!

All the same, make sure you get the latest update for X13 - second link down on the op! could well be your issue.

Gets me 5Mhs  on 2 x R9 290 (non x)

Will have to do for now.

Hey all, I am solo mining and just found a block 3 hours ago but it is not getting confirmed.  Is something up?

Do I need to check anything on my end?  In the past they did not take this long to get confirmed and credited.

New to this coin and solo mining.

Thanks!

Was away for the weekend but back now and will be on here soon to chat!

We should vote on the mintpal, but its really hard to get the first position without investing some bitcoins. Would be nice if we had someone contact at mintpal to get things implemented? anyone?

another shitty launch with retarget every hour, to feed whale farm

when you dev realise that diff 10 after 10 sec is not good, because it doesn't mean the coin is not instamined, it mean that a huge farm have instamined it and no coin for small farmer...
