The best I've seen so far with a riser is 315 kH/s ...which hurts me because I know it probably does 330-340 running in x16 mode on a board slot.

Maybe something we can look forward too in a future release version of cudaminer. I think I read somewhere where his next release he plans on doing the hash compare in the gpu without having to pass it in and out of memory through the bus. Which apparently a USB cable a foot long slows that down a bit.

On a side note kudo's go out to HardwareDecoder, I wanted to run a headless ubuntu or xubuntu rig from a USB flash but I had a helluva time and finally gave up. While I'm not great at Linux I can manage and definitely concede it would be my optimum choice. I still want to try disabling everything in bios when I get home and give 6 cards a try on win 7 64 one last time. In the meantime it would be super helpful to the community out here if HardwareDecoder could give some specifics on his Linux setup. Ie what distro how did he install usb cd etc. also some tips or examples of what he changed hand editing the card bios's for bios overclocking since we all know there is no msi afterburner on Linux lol

Much coin!

It's not the USB cable...right...it's the x1 operating mode. Having a cable between the card and the MB wouldn't slow anything down, unless the signal integrity cause a slower operating mode, which it doesn't...it's x1 on board or x1 via cable.

What problems are you having with Linux? I have the six card setup running in Ubuntu 12.04 with latest Nvidia drivers and latest cudaminer...There's some hoops you have to jump, but google had me covered.

The short story was I couldn't get ubuntu or xubuntu to ever get past the loading screen. It would hang on the little spinning logo thing. And that was 1 vid card plugged directly into board. Much more to the story though. I have setup ubuntu and xubuntu on my gaming rig to run from a usb flash and cgminer for the amd card so I've done the whole process before at least on a different system. I could boot a install usb flash for both ubuntu and xubuntu but when I'd select the install option it would just hang. I then burned install dvd for both vers, yanked my burner out of gaming rig and tried to use it to install to an 500gig drive I had laying around. It went through the install but same deal on boot. Stuck on either logo spin or some install got to a Unix prompt shell like it wouldn't load grub. But keyboard and mouse would not respond.

HardwareDecoder: Try the msi 990fx gd65 or the m5a99x pro for 6 and 5 gpus per rig. 990fx sabertooth does 5 gpus as well.

I already have a Gigabyte GA-Z87X-OC in hand and will have to wait until next Monday to receive my first graphics cards for it. I'm really looking forward to see what kind of performance I will get just on stock speeds.

I use Xubuntu for my dedicated miner. I assume the spinner image freezes, correct? Have you tried switching the monitor connection to the video card? Unplug monitor and plug it to the video card, after Xubuntu loads the video drivers kick in and you'll have to use the monitor with one of the video cards. The OS is running but it won't work with the motherboard onboard video.

As far as hanging during installation, this wasted a few hours of my time too. I figured out what caused it. Leave the network cable unplugged during installation. If you leave it plugged in it will try to download some updates, but the network connection might hang somewhere.

Install Xubuntu offline, then it will be able to complete the whole process.

This guide rocks btw: http://blog.truepps.com/complete-guide-to-mine-scrypt-on-xubuntu-13-10/

Wish there was something like this for cuda.

I plan to use this guide for Cudaminer and Linux:

http://www.reddit.com/r/dogemining/comments/1yzd0n/4_x_750_ti_linux_build/cfp9hao

You compile CudaMiner yourself, but it needs a few source code tweaks.
