Well, everything is faster and i appear to be as stable as i used to be

I first tried 11.5x200 to test with the results you got, which gave about the same results for me. Then i just tried my luck and set 213x12 2.5-3-3-11. And guess what, i'm still 100% stable. That means i may even get higher. Some kickass ram seems nice at this moment too

Oh, one more thing. When i do a cold boot I have to switch off the
psu first or i get no boot. I can live with that, warm reboots are no prob. Just look at it as a security feature
edit: central brain identifier tells me 1T indeed
