G.Skill Sniper DDR3 2133 8GB (4GB x2) installed in the ASUS Sabertooth 990FX R2.0. BIOS has RAM set to 2133 with manufacturer's timings and voltage. Installed in dual channel slots.
Asus Suite II and AMD Overdrive show RAM running at 1066MHz speed. Using an FX-8350.

Is this an error with my RAM or is that the correct MHz for 2133 RAM? I always was under the impression that the actual MHZ was the named timing...

DDR means Double data rate
So the real speed would be half of what is displayed but the effective clock speed would be double i.e. (2X1066MHz=2133Mhz) when you are using pairs of memory modules to work on dual mode.
If you run a benchmark test, it will show you effective frequency since it tests actual performance. But even some software like CPU-Z, will show clock speed(Real Speed) of your RAM, they will show "MHz" or real frequency.
There is nothing wrong with that and you don't need to mess with the bios or anything in regard to that matter.
Everything is good with you :)

named timing is more like CAS latency. If ram is set to 2133Mhz in bios, it is set to that speed. the 1066MHz sped is most likely the SPD Speed being read. Tested speed is 2133MHz. This is quite common but the ram is actually running at 2133MHz.

So there is no problem, Hope this helps.

No issue at all. Because these RAMs are DDR (Double Data Rate) so 1066 * 2 = 2133 MHz. CPU-Z is showing correct frequency. Your RAM is ok. Don't worry :)

Thanks guys that know what they are actually talking about, EasyLover & Brarboy. That's what I had come to believe after looking over XMP profiles, 2133s all showed 1066MHz, 1600s all showed 800MHz.
Thanks again for the reassurance.........
