New computer build

[Pycno]

I cant understand what has happened but the ram I upgraded with is now working perfectly fine now at 6x2gb 1600mhz with timings at 8-8-8-24 (slightly below rated).
No instability, its really weird that it is working now as I have not changed anything within the conputer and I tried every kind of bios setting earlier.

The problems I had before has changed my view on buying ram. I used to think one could match almost any ram and just run them together at the speed of the slowest stick I now believe its safer to just buy kits to be certain - sometimes different ram sticks will not work as well together.

Anyway, I currently have three monitors connected to a 5970 gpu. Due to limitations of this card I can only use half of its resources for wow, would it be possible for me to install an additional card (radeon 5850 or 5770) for use with innerspace multi gpu rendering (not crossfire in games)?

Is there any issues or downsides to 5 box with main running on one gpu and the slaves rendering from another? Slower window switching?

I can answer some of my own questions now :P

I installed an additional 5850 and it surpasses all my expectations, worked perfectly. I already had ati drivers installed so I just inserted the card and booted up and was good to go.

With this new card installed I can:

- use my big screen without replugging any cables
- have all four displays enabled simultaneously
- run my main toon in WoW at almost the highest graphic settings (nerf shadow detail)
- let the 5850 render four WoW windows with slave toons
- let the 5970 render just my main toon
- render all five windows at the same resolution (1920x1200) for pixel perfect mouse broadcasting
- run slave toons with much higher background fps
- run slave toons with much higher graphic settings (used to be everything at absolute minimums)

- With Trifire enabled I am also able to play Dragon Age: Origins in Eyefinity, previously I didnt do this as I had to disable Frame Buffer Effects to get playable framerates and the game is unplayable without them

- Possible performance gains in other games
- Disable CrossfireX for whenever I want troublefree compability mode

GPU usage on my main is now around 45-50% with every setting maxed out except for shadows which is one notch below max. With shadows at max gpu usage rices to 95% right away and fps remains at 60 but will drop occasionally.

GPU usage on slaves is around 40% so I have plenty to go on for Cataclysm also.
Also overclocked the cpu to 4 Ghz and that cant hurt either.

This has been a huge upgrade and I feel like I have a brand new computer =)
