Performance Impact of Lower RAM Bus Speed

I'm looking at DL380 specs for some new VM hosts.  For the memory configuration I'm after, the bus speed would drop down to 800MHz. 

 

My question is how much of a performance impact will this cause?  Will it be evidently slower than the higher bus speed under all workloads, or just in specialist scenarios?
