Yeah, ok, it all looks great, but how do they work together outside of a test laboratory in a real world home built pc?

That question was answered very quickly, without any special fiddling about required beyond normal setting changes.

When the Corsair kit was installed, the usual 'Memory Has Changed' screen popped up. No big deal, a simple check in the UEFI/BIOS looked like everything defaulted to ensure a successful post and bootup. Yup, that's exactly what took place. Corsair took the right approach IMO to set the profile to default to DDR3 1333. At the next restart, it was a simple matter to set the manufacturer's recommended rated speed of 2133, CR 1, 9 11 10 27, tRFC 171 on Auto DRAM V. Posted and booted right up.

Yeah, ok, how about if 8GB isn't enough RAM for me?

Figured that might be a question asked. Here is the finding. To make it more real, often pc builders buy components at different times. This can be problematic, but that is best discussed on a case by case basis. Back to the answer. Purchased on purpose a kit from a different batch, even the serial numbers were way apart. After they were installed, the usual 'Mem. Change' screen again, but at F10 - Enter, it posted and booted right up! No increase of DRAM V. was required. In fact, with it set to Auto, the 'Read Only' actually shows the voltage to be 1.472v's (by meter, it was just below 1.50v's).

Note that CPU-Z X.M.P. for this RAM shows wrong. In the UEFI/BIOS, Memory-Z, it shows correctly.

Conclusion? I would say MSI mainboards and this RAM are going to work out just fine together. :biggthumbsup:







 
Another follow up report. The MSI Z68A-GD80(G3) continues to amaze me with this RAM! Keep in mind, not all CPU IMC's can handle these RAM speeds especially when OC'ing the CPU also. Without too much trouble, able to set the Platinum 2133 'rated' RAM (3770k CPU) to 2400. tRFC was set at 210. DRAM V. in BIOS required a setting of 1.5955v's. tRFC and perhaps some other timings may be able to be tweaked more, but for my tests, wanted to ensure stability with the least amount of experimentation. For some reason, CPU-Z SPD reads the profile X.M.P. timings incorrectly. BIOS Memory-Z does show them correctly. Also note that two of these kits for a total of 16GB are being used which is 'not' recommended by Corsair personnel. As always, my settings and results are not guaranteed to work for everybody.
