I was aware of that, but in my mind that was over all the slotsah well
Nope, that was over one slot. I'll put in the 2 risers I currently have now. Pics and a more detailed description will follow in a minute.

My two Twin Frozrs
RAM and my big Riser
Cards "securement" and rear IO view
So today I got my second riser so I decided to install my second GPU. Waiting for the third riser with the third GPU.
Unfortunately when I plugged it in I noticed one of the GPUs had a significantly lower hashrate than the other (whether I used the powered riser or the unpowered riser didn't matter), so I took it upon myself to go and flash the BIOS of both cards to unlock the PowerLimit and set it from 35.5W to 65.5W. Unfortunately this did not help much either (it did increase the hashrate of both cards, not by very much tho...)
I'll post screenshots in a second.
Edit:
Screenshots:
Hashrates with the x64 Binaries
Hashrates with the X86 Binaries
Today I received no new parts unfortunately.
I did however receive the tip that I should update the H81s BIOS, which I did. Turned out to be a great tip, now both of my cards have the same, high hashrate.
I have also taken the plunge into mining maxcoin with my 750Tis, with which they are getting this pretty hashrate:
I'm using these settings to mine:
-L 256 -l T1024x24 -m 1 -i 0
They were recommended to me directly from the cudaminer creator and they're working great.
Clockrates are visible in the screenshot, but just to re-iterate:
I'm running a 135MHz OC for the GPU core and a 500MHz UNDERclock for the Video RAM
I'm getting 320mh/s total for 2 GTX 750Tis
Edit:
Getting even better hashrates with
-L 256 -l T1280x24 -m 1 -i 0
