Pff, now I need some help:

trying to get my memory up to speed.
Currently running:
227x19=4313Mhz CPU speed (100% stable with 6x memory multiplier)
227x8=1816Mhz memory
227x17=3859 Uncore
AMP +800mv

CPU 1.275
CPU PLL 1.88
QPI/DRAm 1.45
IOH 1.45
IOH PCIE 1.5 (tried up to 1.7, no result)
ICH 1.1 (tried up to 1.3, no result)
ICH PCIE 1.5
DRAM 1.67
DRAM ref AUTO

CPU Spread Spectrum disabled
PCIE Spread Spectrum disabled
HTT enabled
c1e etc. disabled

DRAM timings: 9-9-9-24-2T (just to be sure the timings aren't to tight)

No idea what to do next. What are you guys running for QPI/DRAM and IOH while venturing for 1800+Mhz of speed?
Or I'm I just having bad luck and hit the max my IMC could handle?
