Ok, I'm assuming that your RAM is using Samsung HCF8/0 or Elpida chips because of the voltage and the chips themselves, thus we're going to keep the voltage relatively low to make sure that we won't harm your chips.

Let's try hitting 200MHz BCLK now:

CPU Features
PPM = Disabled
EIST = Disabled ( automatically )
CxE = Disabled ( automatically )
Execute Disable Bit = Disabled
Virtualization = Disabled
Hyper Threading = Enabled
Active Processor Cores = All

Memory Settings
IMC Configuration = Enabled
Channel Configuration = Independent
Channel Interleaving = 6 way
Rank Interleaving = 4 way
DRAM Timing Control = Manual
tCL = 9T
tRCD = 9T
tRP = 9T
tRAS = 31T
CR = 1T
tRFC = 80T
tWR = 9T
tWTR = 15T
tRRD = 7T
tRTP = 9T

All voltage settings
CPU Core Voltage = +120mV
CPU Vdroop Compensation = Enabled
CPU VTT ( UnCore ) Voltage = +440mV
1.8V PLL Voltage = 1.856V
CPU Clock Amplitude Ctrl = 0.900V
DRAM Voltage = 2.00V
DIMM1 Vref... DiMM3 Vref DQ = -.500 all
X58 IOH Core Voltage = 1.24V
X58 IOH VCCA 1.1V = 1.125V
X58 IOH VCCA 1.5V = 1.530V
ICH10 SB Voltage = 1.530V

Quantum BIOS
System Turbo = Enabled
CPU Bclock ( FSB ) = 200MHz
QPI Link Fast Mode = Enabled
QPI Multiplier = x18
CPU Core Multiplier = x20
CPU UnCore Multiplier = x20
Memory BUS Multiplier = x10
CPU Clock Skew = 0ps
IOH Clock Skew = 0ps

Let me know how it went ( make sure you use the G13 BIOS with these settings )
