hmm ok this is the big difference on bandwidth r3e vs classy

basic..
classy main bandwidth on reduction of Cl on equal ram speed is the RTL's
rather than the subtimings of Read to Write
r3e gains bandwidth from lower Read to write than classy

uncore 4k dram 2000

R3e - RTL for any CL on R3e is best at 58,60,61
Classy - CL7 is at 53,56,58,CL8 is 58,60,61 CL9 is 61,63,64 etc


on CL8's the R3e is faster.. but when it comes to CL7 classy bandwidth is higher with lower latency


uncore 4k dram 1600
this is where the classy starts kicking r3e butt on latency
R3e - RTL 64,60,61.. on any CL's is optimum
EVGA - CL7= 2k C9 rtl's, CL6 = 2k C8 rtl's , CL5 = 2k C7's RTL's,

Vdimm Scaling
I am assuming this is the reason for r3e.. its because of the Read to Writes

r3e = 2k C8 = 1.52v , 2k C7 1.6v
classy = 2k C8 1.5v , 2k C7 1.6v
r3e = 1600 C6 1.5v.. and overclocking on this fixed preset is the same classy on vdimm
classy = 1600 C6 = 1.5v
ok this where i cheesed of with r3e
normally in any other mobo ure 2k C8 = 1866 C7 = 1600 C6 same vdimm.

And here is actually the cool part about r3e
Pro's of R3e
Its easier to clock 2000 compared to classy as the rtl's are more or less the same all out. So just the vdimm and ure qpi voltage for ure 2k rams and the 2k C8 and C9 is faster than classy
Cons of R3e
Above CL8.. on 2k .. not going to make much of a difference.
