er yeah sorry, i meant to take the fans and /shrouds/ off the gpus, not the fans and /heatsinks/. that way the chassis fans blow air directly over the heatsinks and out the back. you can also block the rear vents to force the air over the heatsinks.

Average of 11c drop? Nice!

Makes sense, I was wondering if that wasn't what you meant to say. I always wondered if that would help just never took the time to try it. Nice pictures.

Hi everyone,
As per my previous post I have an 8x 7970 system running CentOS 6.3 (64 bit)
While I was away for most of this year someone at the office re-installed the OS and can't seem to get the Catalyst drivers working. I have Catalyst 12.10 which is what I was running before and don't want to mess with the system.
However when I try to install Catalyst I get this error I get in the install log.
Code:
cat /usr/share/ati/fglrx-install.log
Supported adapter detected.
Supported adapter detected.
Supported adapter detected.

Supported adapter detected.
Check if system has the tools required for installation.
fglrx installation requires that the system have kernel headers. /lib/modules/2.6.32-279.el6.x86_64/build/include/linux/version.h cannot be found on this system.
fglrx installation requires that the system has gcc tool. gcc cannot be found on this system.
One or more tools required for installation cannot be found on the system. Install the required tools before installing the fglrx driver.
Optionally, run the installer with --force option to install without the tools.
Forcing install will disable AMD hardware acceleration and may make your system unstable. Not recommended.I am sure this is an easy fix and it is laughable that I cannot seem to fix this myself, but I am not actually very computer/hardware savvy.
Any help would be much appreciated.

As of the oclHashcat requirements you need at least Catalyst 13.1 (http://hashcat.net/oclhashcat-plus/ ). Also if you haven't done yet you should download latest oclHashcat suite (see previous link).
The error says you miss version.h header file, that means you need some kernel headers (linux-headers-$(uname -r) for example). BTW: in centos it should be yum install kernel-devel if I remember correct.
Unfortunatelly the wiki setup instructions are mainly focus on ubuntu ( see http://hashcat.net/wiki/doku.php?id=linux_server_howto ) but there are several forum post + other instructions around (google it) to setup catalyst.
Code:
yum groupinstall "Development Tools"
yum install kernel-devel kernel-headersRE: 8 x AMD HD7970 @ 1050MHz - Dr0pB3ar - 08-20-2013
Thanks philsmd,
Do you know if ubuntu accepts 8x graphics cards? when I bought the system (mid-late last year) it came in CentOS because apparently at the time it wasn't possible to recognise all three adapters? To be honest I would much prefer linux because that is what I am used to.
Cheers,

yes, ubuntu works with eight graphics cards, the same as centos.
