[ANN] cudaMiner & ccMiner CUDA based mining applications [Windows/Linux/MacOSX]

[ManIkWeet]

could you try running pooler's cpuminer in screen, and if it terminates too ask for an improvement in his code (pooler's cpuminer has its own thread on bitcointalk).  I can then just merge his fixes in

Christian

I can confirm that pooler's cpuminer does indeed function in Linux screen, I can not confirm cudaminer though.

I will never post pictures again when everybody feels like changing my design

Hot air comes out at both ends of the card. About twice as much at the rear though.
It is futile to PUSH against it with a fan as it will slow down the outflow of hot air
and possibly lead to hot air rebreathing.

The only feasible way was to push in cold air from the top, and additionally
sucking out some air (a mix of hot & cold) from the front.

The fan combo works, no longer am I thermally throttled.

This all is moot anyway when my risers get here.

Christian

I'm convinced that you're seeing the result of forced air from the "wrong locations". Everywhere I read (and my own experience), is that the side where you have the PSU placed, is actually a fan *intake*. Look at how the airflow works in nearly all traditional desktop ATX cases - cold air enters the front of the case, hot air exhausts at the rear of the case. The titan cooler is designed to optimal performance in this specific scenario.

If only ... I .. could reach .. that fan, and ... check .. how ... damn, can't reach it...
Try it, now I'm obsessing about it! Sorry for being pushy!

[djm34]

Agree, but I think Christian was referring to heat radiation from the pcb of the cards.
And the problem with these long card this hot air is more or less trapped in between the cards
(sure it is supposed to go up but not fast enough, reason why  I was suggesting to put the fan sitting on top rather
in pull, so it can extract the hot air and obviously on the rear of the card (the end of the card where the vga plug are so
that it doesn't interfere with the intake fan of the card.)

[ManIkWeet]

Christian forgot to remove the plastic in the back of his MARS cards, the plastic got sucked in by the MARS cards, I am pretty sure air goes from the fan through the heatsink towards the monitor connector points (the "back")

Nice, BTC price on the rise again, soon back to 700 USD. LTC also rising slowly, it looks like the mtgox crisis is over

Have you tried to use a dummy plug? Very easy to make and needed for years for AMD. AMD fixed things driver-side to resolve this for miners but Nvidia may not have needed to before now.

my goodness, the gpu coin launch has been a revelation in what level of multi-area incompetence mankind is able to achieve

what exactly went wrong by the way? Would anyone care to elaborate?

Blower type coolers, 100% sure draw air from the front of the card towards the back where the monitor plugs are.
I'd suggest both a front intake as well as a side exhaust fan, the same fan that blows cool air towards the pcie slots, flip it, and have a second fan pointed at the cards from the front (pcie connector side) perpendicular to the pcie slots, so to speak. The best solution would be some sort of duct to funnel cold air to the gpu's intakes and cool the board while at it.

Having some warm air reach the psu's internals doesn't sound like my idea of fun :p

Trying to get 6 750ti's working correctly.

Right now it appears that gpu3 is not hashing, any idea to figure out why. When cudaminer starts it says starting 6 threads.

This in W7 32bit since it was what I had laying around. All 6 gpu's show up in device manager as ok.

ego and incompetence to be more precise (don't understand: someone had already stepped in when the new "dev" team went into the game telling he had experience with that while the only thing he had was a video for a forthcoming coin).

All this masks the fact that another scrypt:2048 (a vtc clone) coin has been released this weekend without any publicity and seems to do rather well: execoin

[gameraddikted]

Hey guys, I'm running five 780's for mining scrypt, and only the launch config mentioned in the pic worked as I copied it from another guy. So we're talking 420kh/s by each, all OC'ed, where I know it should atleast be 550-600 kh/s.

Does anyone have any better launch config for the new Cuda miners?

Hey just an idea. Did you ever try running cudaminer on fully auto without any extra settings? That's what I found to work the best for me. I'm running a single 780 Classified and for regular scrypt I'm a decent bit over 600.

Almost nothing for the second fail launch except that instead of generating 20k gpu blocks, the amount was generated a la panda between 0 and 1M gpu.
In consequence the IPO and the premine was kind of small in comparison... (other problems occured after that in the next to next (to next) attempt...

Actually, they should have fixed the fork of the first launch instead of redoing a complete new coin with a complete new "dev team" so the next episode is next sunday... lol

[bigjme]

yep next sunday, and they need to switch the code to keccak

[djm34]

I think it is their real problem: They are not able to stick to anything
(hopefully, they should have the whole week to premine whatever they want.)

[bigjme]

yeh, i mean why the hell would you release a coin with pre-mine, and not do any of the pre-mining xD

Hey Christian.

Quick question, can I use Cudaminer on something like [Suspicious link removed]?

Do I just set it up like normal and bobs your uncle?

well your posting isn't really clear when your URL gets replaced by [Suspicious link removed].

And what on earth does the second sentence mean?  My uncle has no boobs

Christian

Stupid thing.
It was a link to hashcows.

Will cudaminer work with multi-pool mining?

Yes. But if you want profit hashcows isn't the pool you want to turn to
Try clevermining, middlecoin or wafflepool. Probably in that order.

I beg to differ...According to http://poolpicker.eu/ HashCows is winning right now

We should expect that by the end of the week, they will have accidentally premine the whole coin and will have to redo a new launch with another algorithm.

[cbuchner1]

also consider mining on coinshift.com

This multipool tries to be less damaging to the coin ecosystem by gradually shifting hashing load between coins, and by mining a couple of coins simultaneously instead of just jumping onto the currently most profitable coin.

If you look carefully at the numbers versus the curve, you'll see that it doesn't match at all.
for the 8 first days hashcows is well below 0.01btc but still it shows up with higher than that in the number (they made 3 good days at the end of the month and that's it).
