Yo Alien Grey,
thank you for the LinX link.
I ran 20 loops LinX "all" without errors with these settings:

The highest temp on both cores was 79°C which made me a little shaky.

Cetero censeo:
I can´t get my system stable at a memory speed faster than 1,200 MHz.
No matter what I do

It's a strange problem. Everything runs stable with DDR1200MHz. When you try to change the DDR speed you can't have it stable anymore although the memory seems to be 100% stable.

What happens when you don't advance the DRAM CLK Skew on Channel A/B?

[Fritz_the_germ]

I haven´t tried LinX without advancing channel A/B.
But I know for sure that I´ll receive a funny DIMM Clock Fine Delay about 1T on DIMM 1, 10T on DIMM 2, 1T on DIMM 3, 10T on DIMM 4.
That seems to be a very screwed up timing.
I set 300 ps advanced on channel B and just 250 ps on channel A because the lines of channel B are a little longer so I fell like making it even. Got me?

It's funny that it works for you. If I try to change one of the DRAM CLK Skews I get "red alerts" in ASUS PC Probe II.
