Well I doubt it was just setting that timings that killed the BIOS. But things happen!

I suggest you do manually set your timings and voltages, Here is where I would start with that ram, then work your way down from the higher numbers, testing after EACH timing change ONE BY ONE. You may also try bringing down the voltages later if you like
