ram timings

[regnad]

hello all, i just completed my first build and used corsair ram with a 7-7-7-20 latency. in cpu-z it says i have a 8-8-8-20 latency. whats up with that?
second question, per my hardware in my profile, would i benefit greatly to build a raid 0?

Can't advise on the Raid setup, but you'll have to manually set your Ram timings in BIOS. Look in the AI Tweaker section for DRAM Timing settings. You can just set the 1st 4 to 7-7-7-20 , leave the rest on auto. A Guy
