Ola amigos!
Consegui estabilizar em 3.6 (20 x 180) com 1,20v
AI overclock em X.M.P.
memorias em 1804 Mhz
C1E - DESABILITADO
HT - ON
a maioria das configurações de voltagens em auto... (over bem simples, NADA REFINADO)
O problema é que nao estou conseguindo estabilidade com as malditas memorias a 2000 Mhz, segui as configuraçoes passadas em um forum de apoio da prória G.Skill e funciona tudo no windows... PRIME NEM PENSAR
ESTAS SÃO AS CONFIGURAÇOES RECOMENDADAS POR ELES:
This setting is to run DDR3-2000 F3-16000CL9T-6GBTD on the ASUS Rampage II Extreme motherboard. In this scenario, the Intel Core i7 920 is overclocked to 3.6GHz which is perfectly safe for this combination. You can also check the temperature in your BIOS to confirm that it is not overheating.
AI overclock - manual
OC from CPU level up - auto
OC from Memory level up - DDR3-2000
CPU Ratio setting - 18 for 3.6GHz
CPU Turbo Power Limit - disable

CPU Ratio Setting - 18
C1E Support - disable

Adjacent Cache line prefetcher - enable
Intel Virtualization tech - disabled

Execute Disabled bit - disabled
Intel HT Technology - disable
Active Processor Cores - all
A20M - disabled
Intel C-STATE tech - disabled
BCLK frequency - 200
PCIE frequency - 100
DRAM frequency - 2000 MHz
(FICA EM 2005 MHZ)
UCLK frequency - 4000 MHz

QPI frequency - auto
Dram Timing Control
DRAM CAS# Latency - 9
DRAM RAS# to CAS# Delay - 9
DRAM RAS# PRE Time - 9
DRAM RAS# ACT Time - 24
DRAM REF Cycle Time - 74
(SÓ APARECE 72)
DRAM Timing Mode - 2N
All others can be on AUTO
EPU II Phase Control - Full Phase
Load-line calibration - enable
CPU differential amplitude - auto
Extreme OV - disabled
CPU voltage - 1.32V
(FUI DE 1,1800 até 1,375 e nada de estabilizar)
CPU PLL voltage - 1.85V
QPI-DRAM voltage - 1.55V
IOH voltage - 1.35V
IOH PCIE voltage - 1.60V
ICH voltage- 1.20V
ICH PCIE voltage - 1.60V
******(ESTOU EM DÚVIDA NESTAS VOLTAGENS EM AMARELO, NÃO SEI EM QUAIS DEVO MEXER PARA AJUSTAR E MUITO MENOS PARA QUE SERVEM)
DRAM Bus voltage 1.65V
CPU spread spectrum - disabled
PCIE spectrum - disabled
CPU clock skew - auto
IOH clock skew - auto
As a side note, this board is pretty nifty in that you can have different BIOS profiles saved. For example, if you have a setting for DDR3-2200 @ CAS 9 and DDR3-1700 @ CAS 6, you can save both complete settings of your BIOS and simply change back and forth when you want to instead of changing every single voltage and timing to operate at different speeds.
Thank you

Se alguem tiver uma luz agradeço, to desconfiando que o problema de estabilidade esta nas memórias...
