I have three modules of kvr1333d3n9/2g. Here how it looks like in the CPU-Z with the default (no overclocking) BIOS mode
So, CPU-Z is clear that my memory is PC-10700, which means DDR3-1333 according to http://en.wikipedia.org/wiki/DDR3_SDRAM.
(Excuse me for the fuss. In the first edition of my question, I confused the memory transfer rate with the NB frequency.)

■Does it mean that I can run it at 666 MHz instead of 533?
I see in by BIOS that base frequency is 133 and SPD multiplier is x10 so that in result I'm getting 1066 (1333MHz). I do not understand
■why do I have 1333 MHz instead of 666 MHz? Afaik, DDR3 clock cannot be higher than 1 GHz.
■Why does BIOS report 133x10 =1066=1333?
I see in the DDR3 Wikipedia article that there are DDR3-1333 running at 667 MHz and DDR3-1066, runns at 533 MHz. These are two different memories/modes. Why BIOS confuses them for me?
■Should I degrade the CL-tRCD-tRP timings from 7-7-7 to 9-9-9 if I manually switch from 533 to 666?
■I have the GA-X58A-UD3R 3-channel memory motherboard, with 2GB in each channel. It still has 3 free slots. Which kind of memory is compatible for expansion? Why do all the multichannel memory controller guidelines like this say that all the slots must loaded with absolutely identical load, including manufacturer and capacitance, whereas my motherboard manufacturer says that I can have 4 memory modules working in 3-channel mode
What does this picture mean? Do they mean that I may have two channel 1 modules (in slots 1,2) unmatched with single modules in slots 3 and 5 (I guess that slots 1 and 2 are connected to the 1st channel, 3 and 4 to the second and 4 and 5 to the third) or it is possible to have two different modules in the first channel that expose the same combined characteristics as the single-module loads in the rest of channels? Can I buy memories with higher ratings to work together with my memories in 3-channel mode? For instance, I see that there are pretty cheap 4-GB modules
■Can I just add a 2 or 4 GB module, likewise KVR1066D3N7/4G, into the first slot to have 2+2,2,2 configuration in 3-channels? How would this affect the performance? Or, can I move one existing 2 GB module into the first slot and place a 4 GB module into the liberated channel? Should the new module be DDR3-1333 and better? What if I purchase 2+4 and arrange the modules as ch1=2+2, ch2=2+2, ch3=4?
■Why do I get the "To insert a picture or a flash item in your message, you need to be a confirmed member. If you have not done that yet, confirm your email to validate your account." message while no confirmation was sent to me in the Welcome Email (I have signed in through Google Account)
