Topic: Building a 6990 Rig - Operating System - page 3. (Read 14928 times)
I'm running a 6990 + 2 6950(unlocked) in Ubuntu 10.04 just fine with 11.3....
I have both windows 7 64 bit machines and windows xp 32 bit machines. The 5870's do the same in both machines, 330k at 900mhz clock. I use the latest stream as I could NOT get 2.1 to work.
The windows 7 64 bit machines run smooth an can be used for something else, the XP machines feel doggy but produce the same hash rates. If you are not using it other then mining it does not seem to matter.

I threw Win7/32bit on my box and it is slow as a dog. I hope 64bit is better.
So since it sounds like Linux is currently out of the question (or at least not optimal), which version of Windows should I use (if it matters)?
Linux is not an option for a 6990 rig. ATI has not released the Linux drivers yet.
Pretty damn important piece of information to know. ATI have a timeline on the drivers?

Core and mem speeds can be tweaked from Linux. If you want to change anything beyond that such as voltage you need the Windows programs that do that since they don't exist on Linux.
Ubuntu is a pretty popular distribution and quite a few people use it here so it would be easy to get help.
There is a thread here with some nice instructions for getting it set up https://bitcointalksearch.org/topic/m.47174
It doesn't look like the ppa:ubuntu-x-swat/x-updates repository with the update Radeon drivers is not available anymore, it gives me errors when I try to update. The radeon drivers in Ubuntu 11.04 are newer than those but 11.04 is still beta (which might not be a problem). I haven't tried upgrading yet.
EDIT: It looks like the packages can be downloaded directly here if the apt-source isn't available. https://launchpad.net/~ubuntu-x-swat/+archive/x-updates/+sourcepub/1398782/+listing-archive-extra
OR possibly get the updated packages from the 11.04 version.

Can you elaborate on "tweaking every little aspect"?
I know I'm definitely going to underclock the memory speed to suppress the power drain as much as possible, and play with the core speed to find a sweet spot for Mhash/W vs Mhash/sec.

I think once the nuances of drivers and SDK versions are worked out, the performances on each OS are roughly the same barring anything else. So it comes down to preference and what you intend on doing with it and what you're comfortable with.
If it's a dedicated mining machine then Linux is good for setting up and letting it go.
If it's not a dedicated machine or you want to tweak every little aspect of the card then you need x64 Windows.

I'm building a rig with the immediate goal of running just a single 6990, and then adding on another 6990 in a month or two.
What will give me the best results for Mhash/sec currently, Linux or Windows? Which distro of Linux or version of Windows should I load onto it?
Building it with the following:
Case: Cooler Master HAF 932
Motherboard: MSI 870-G45 AMD
CPU: AMD Sempron 140
RAM: 2 gigs
HD: 16 gigabyte solid state drive
Power Supply: 1000 watt
