New to this keep getting a "stratum authentication fail" tried on 3 different pools so I am not sure what I am doing incorrect, here is one .bat example:

cudaminer.exe -r 10 -R 30 -T 30 -H 1 -i 0 -m 1 -d 0 -l L32x8 --no-autotune -o stratum+tcp://stratum-east.hashfaster.com:3333 -u fior -p x

Where is the problem? I am also using dual 9800 GTX (I will upgrade here soon just want to get the learning curb out of the way a bit more) so if you see any other issue feel free.

-u fior -p x

Should probably be:

-u fior.workername -p x

Where workername is the name of the worker you set up on the pool.

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 Wink

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 Smiley
Try clevermining, middlecoin or wafflepool. Probably in that order.

Hi, Christian

It is impossible to run cudaminer via screen:
screen ./cudaminer
[screen is terminating]


I have made a small investigation (see below),

Could you make a little code improvement, because now the only way to use cudaminer with screen
is to run pure screen, and execute cudaminer from screen session. It works fine.
But if you want to have the same, but executed from shell script
- there is a SIGHUP signal, which terminates screen completely.

It would be great do have screen <-> cudaminer full interoperability.

Regards
JK

My feeling is that I'm leaving about 10-30 kH/s per card on the table because of x1 slots / risers.

this will be fixed at the software level soon'ish. I will be using risers myself, so it's in my best interest to fix it.

Christian


This is great news, thank you, Christian.

6x 750 Ti's (OC'd to stable + BIOS Power Mod)

Pretty please could you edit your post to include the exact make and model of your cards? It helps other people greatly Smiley Thank you!

Will update that post now.

Those with hash rate problems on their newly acquired 750 Ti's: please also try with a 32 bit cudaminer build and compare...

Tried x86 cudaminer with my six cards in W7x64. Peaked a little higher than on x64. I was looking at 1740-1750, with x86, it will peak from time to time at 1770

When Cudaminer does this, attempting to mine afterwards results in a very very low hashrate (usually ~27KH/s on Scrypt). Is there anyway to resolve this without having to reboot the computer?

Any ideas?

Check you clock speeds after CudaMiner errors out. When I get errors out of CudaMiner, my GPU goes to "2D" clocks and gets locked there. Another way to get out of that mess is to launch Device Manager and then disable and re-enable the offending GPU.

Thanks. Enabling/disabling the GPU should be possible and scriptable I think.

Hi, Christian

It is impossible to run cudaminer via screen:
screen ./cudaminer
[screen is terminating]


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 Wink

Christian,

Noticed that picture with your triple card setup with a fan on top and the PSU on the rear of the cards.
If I'm seeing it right and those are blower type cards, I have a suggestion for you: maybe try having the fan on the rear of the cards, instead of the PSU, and blowing cold air *into* the cards. I think the "titan" blower cooler design is particularly effective with an airflow that runs from rear to front (in other words, from near the pci-e power connectors into the monitor connectors).

Cheers,
Myagui

hot air comes out the rear end of the cards with the intensity of a 800 Watts blowdryer.

The purpose of the fan/PSU combination is to make cool air move in the space between the
cards, so the cards fans can pick THAT up and force it through the heat sink. The space is
narrow, so the more air I get into the space, the better.

The problem is even worse with the 3 ASUS MARS cards.

I don't know... the psu seems to sucks air away from the fans of the cards.
I would tend to agree with myagui.
Put a fan in push where the psu is, and put another fan in pull on top on of the other end of the cards.
This way you'll get fresh air circulating between the cards.

I think Christian and I refer to different "rear" locations. I just double-checked my 770 (titan cooler also), and it definitely needs to "suck" in cold air from the section near the PCI-e power connectors, and it will "blow" out hot air around the monitor connectors, just the small hairdryer type experience as described. It certainly does *not* blow out hot air at the section nearby the PCIe slots (if it would do that, it would be nearly impossible to work out a case design that would actually work in favor of these cooler designs).

The PSU as pictured, is causing a negative air pressure that works against the card's fan. Anyways, looks like a quick test given you have all the parts just laying around freely (living on the edge, heh!). Smiley

Cheers!

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

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.

What risers did you scope out? Powered/Unpowered? USB3/Ribbon Cable?

I ended up getting mine off Ebay from some folks in Oregon. Mine look similar to this (http://www.sintech.cn/riser%20card/ST8019C%20PCI-E%20express%20X1%20to%20x16%20riser%20+USB%20cable.html)
