I guess my question is mainly;
1) will long usb cables provide much noise and performance drop? I am talking the high quality, thick insulated usb 3 cables, 5m or so
2) the usb 3 risers should be fine to be connected into x16 slots right? They should connect just to one part I believe? Never had to look at this before
Thanks

the main issues from an engineering perspective are:
- a delay that may be outside specs for PCIe (finite travel speed of signals in copper wire...)
- excessive signal attenuation (this is HF signals after all)
I would not recommend going past 1m... Sure you can try, but I am sceptical.

ccminer behaves really strangely on fuguecoin after a while.
The gpu usage is all over the place.

run Google Chrome
I think we have a fix for this now.After we investigate the alleged memory leakage, we may release an update tonight.

Guys please help, my asrock h81 pro btc arrived and i set it up with pci usb extenders and 6 750 ti , but windows is showing me only 5 cards , i cheked everything , changed slots , but nothing , the best i can get are 5 cards. Is there a driver issue or something else , i have a a friend who has the same board and puts 6 amd cards with no problem.
?
? I hope you get this sorted soon, i am looking at getting that board with the usb extenders soon
right now i am feeling the hate for getting a expensive motherboard as my has
2 x PCI Express 3.0 x16 slots (PCIE2/PCIE4: single at x16 (PCIE2) / x8 (PCIE4) or dual at x8/x8 mode)
1 x PCI Express 2.0 x16 slot (PCIE5: x4 mode)
2 x PCI Express 2.0 x1 slots
if only it was 3 @ x1
as you cant run the x1 risers in the x16 slots i believe?
and i know they don't make x16 usb risers
On a side not, has any tested what difference using longer usb cables poses?
For example mos are sold with 1m cables, but what is stopping you using 5m cables?
please someone test this xD
Yes i sorted it out , i disabled the onboard video and it turned out that one of the extenders was not very well , and now I am a proud 6 x 750 ti rig owner. But i can tell that for good results , you should be using at least 8gb ram , i couldnt get them runnig with my previos settings , wanted more ram.
Interesting, where did you turn off onboard video? I'm running an i3 in mine and couldn't find a simple setting in the bios like my Gigabyte board has.
I also noticed the ram thing but thought it was a page file issue since I was using 18 of the 20gb drive i had in there previously. I currently have a larger drive and 4gb ram in there. I'll have to try 8gb now and see if that is stable.
FYI, it seems I was only able to detect 6 cards when I updated to service pack 1, so if you haven't yet, you'll need to make sure it's all updated.

Can you help me to understand how can I configure CudaMiner to talk to this Pool?
you know there is a README.txt file packed into the cudaminer download...
Christian
D4rk, in case you are still not sure how to proceed with setting it up, even after reading the README, try http://www.reddit.com/r/CudaManager/comments/1zoe39/release_cuda_manager_v121_expanded_miner_options/
Aside from making the set-up process more intuitive, it also offers a number of handy features, such as a good fail-over support and temperature control

You might be running out of memory. Or cudaminer does something it shouldn't.
Are you using autotune?
Are you using autotune?
ccminer uses thrust libraries, cudaminer doesn't.
does GPU memory use grow over time? you can monitor with nvidia-smi (or GPU-z on Windows)
Christian
nope, stays all the time around 187MB/2047MB per card.
EDIT: btw. why does nvidia-smi not show ccminer under Compute processes?
Keep in mind that memory fragmentation can occur, which can mean that although there is a certain amount of memory "free" you may not be able to allocate a contiguous chunk of a given size.... In my own code where I use thrust, I have had to do a bit of wrangling to ensure that there is always a contiguous memory buffer available that will satisfy the allocations that thrust does internally. I do this by making an allocation that I hold onto until right before I call thrust, and then I free it. Once thrust completes, I allocate it again. This is very hokey, but it prevents other applications that use GPU memory (e.g. Google Chrome) from interfering with my application...

I just saw, that HTOP reports 41.2G virtual for ccminer? Do I need to worry about that? ^^

Aslong as it is on, the gpu will run. Just bridge the psu to force it on without a motherboard. Takes a single cable

is there anyway you could try a riser with a long usb cable? 5m or so?
5 meters is rather long. The problem is not to get it works with a 5m USB cable but to find power cables (sata or molex, pcie) that long.
(I think. This was my main problem when I put the amd outside the case)
I plan on using a power supply with the gpus, away from my system, I have a few kicking around

my idea is that i was going to buy an entire system to free up my 780,
but if i can connect my 750Ti's using riser to ym system using long usb cables, they can have their own case and psu outside my case and run using my current system which idles doing nothing all day
has 32gb memory, and a nice powerful cpu, im running 2 vm's and cudaminer at the moment, and still hardly ever hit 1% cpu usage, thats 2 windows 7's and a machine with ubuntu 12.04
that way i could connect 2 750Ti's to my spare sockets and drag the usb cables out of a pci-e slot on my case and to a separate case a while away.
my cpu supports 1x16 & 1x4
so i should be fine to run my 780 at x16 and the risers off x1 and have power left over. those specs are pci-e 3 btw so 1x4 is the same as 1x8 for pci-e 2
christian have you done any testing on this?
and if the sockets will fit into larger ports, such as my 2 spare x16 slots?
i don't want to order risers, and gpus to find out that i need another system to use them in

Hello to everybody,
I am very new into cryptocoin field and I want to try to mine some XenCoin that is scrypt coins
I have a NVIDIA 720M so I think that the right choose is CudaMiner
So I downloaded the last version of CudaMiner from the link in the first page of this 3d, this one: https://mega.co.nz/#!UIBwiATb!6pCkYdYkLYQfMw5nZIQRVCjIi8teFj1_vtLaGNv74gY
Previously I downloaded the XenCoin wallet.
Now I think that I have to register an account on a specific Pool and then I have to link CudaMiner to this Pool.
I have choose this pool: http://xnc.hasher.ca/ but if I go in the get start page of this pool (here: http://xnc.hasher.ca/index.php?page=gettingstarted ) I can't find reference to how configure CudaMiner (as you can see it speack about CGMiner, Asteroids, BFGMiner and CPU Mine but not CudaMiner.
Can you help me to understand how can I configure CudaMiner to talk to this Pool?
Tnx
