Hello Urugamer normally you won't meet any problem running your four memory sticks with your vishera but only at 1333mhz or 1600mhz... indeed those FX processors (4,6 or 8 cores) only accept 1866mhz or more with 2 sticks and not with four...this is a limitation of the memory controller (cpu-northbridge/uncore)  :-\
For my case i'm running only 2 sticks (1600mhz labelled) but with bios tweaking i'm able to run them at 1866mhz and 2133mhz always with 1,50v stock voltage  :D
