You know what... I may have made a mistake thinking I could hit those timings with this ram...

This ram is rated 4-4-4 for 800mhz...... not 4-4-4 for 1000mhz....

So pushing to 940 on this ram......

I tried all those settings (my mch is already at 1.75)...

The system simply will not POST with CAS latency @ 4.
