Under JEDEC#1 why is one at 266Mhz and CAS latency different though? I don't quiet understand that..

Referring to first image.

The spd tab shows your ram ratings at different speeds, no worries.

They shouldn't be different speeds and seem to be bottlenecking my PC.

I tried moving sticks to different slots, setting system voltage in Bios to Auto, then manual and overvolted to +0.2volts after seeing people with similar issues on G.Skills website. http://newgskill.web-bi.net/gstechforum/

None of these seemed to remedy the situation. Hoping I don't need to RMA these sticks.
Those aren't the current memory speeds. Those are the default SPD values for each stick.

At the 266/533 ratio, your memory will default to the lower CAS.

that G.Skill RAM needs 2.1V.. so in your bios set it to +3 as 1.8V is the motherboard default.

They recommend 2.1v, but it's always a good idea to use as little voltage as you really need.

My memory says 2.1-2.3v on them, but at rated speeds they are 100% stable at 1.8v.
