i am not familiar with your mobo but will try.
usually there is a cpu voltage option, its usually set to auto, you need to change this to manual.
then just raise the cpu voltage yourself by a few levels. eg, if ts at 1.38v, raise it to 1.39 or even 1.4v.
regarding the SPD, my mobo is different, but this if this is set to 2.0 it means that the memory is set to 1:1 with the fsb ((cpu host frequency))
so if your fsb is 300, so will be your ram, (as its ddr2 ram its 300 x 2 = 600mhz, your ram speed, this is fine if your ram is rated at 800mhz or 1066mhz, but if its 667mhz its still fine, upto a fsb of 333, as 333 x 2 = 666mhz.)
so set it to 2 for now.
download cpu-z, this will give you all the cpu, ram info you need.
have a look here for 3.2 settings.

here is a guide i done for someone before, 3rd post down.

also found this explanation for you.
MB Intelligent Tweaker(M.I.T.)
Robust Graphics Booster___________ [Auto]
CPU Clock Ratio (Note)____________ [XX] <<<----CPU Multiplier
This should be set to your processors highest multiplier, for now.
so set it to 9
The option will display "Locked" and read only if the CPU ratio is not changeable.
CPU Host Clock Control_ [Enabled]
CPU Host Frequency (MHz)__________ [266] <<<----FSB Speed (Front Side Buss)
PCI Express Frequency (Mhz)_______ [102]
C.I.A. 2__________________________ [Disabled]
System Memory Multiplier (SPD)____ [2.00]
This is a 1:1 divider, memory speed will be 2x FSB.
Memory Frequency (Mhz) 533
Your actual memory operating speed is always show above.
DRAM Timing Selectable_______ SPD __ [Manual]

CAS Latency Time_____________ 5 ____ [4] <--use your rams values, (CL)
Dram RAS# to CAS# Delay______ 5 ____ [5] <--use your rams values (tRCD)
Dram RAS# Precharge Delay_____5 ____ [3] <--use your rams values (tRP)
Precharge Delay (tRAS)________15 ____[12] <--use your rams values (tRAS)
ACT to ACT Delay (tRRD)_______4 _____[auto]

Write to Precharge Delay______6 _____[auto]
Refresh to ACT Delay________42 ______[0]
Read to Precharge Delay_______4 _____[auto]
Memory Performance Enhance__________ [Normal]
dont touch these for now
This setting adjusts a major sytem memory performance timing known as tRD and has a great affect on
overall memory performance. Start out with "Normal" or the default while establishing your cpu overclock but once you
start tuning the memory subsystem and after putting in your high performance memory settings try very hard
to get a stable OC with the "Fast" or "Turbo" settings.

High Speed DRAM DLL Settings________ [Option 1]
******** System Voltage NOT Optimized ********
System Voltage Control____ [Manual]
DDR2 OverVoltage Control__ [+0.300V] <-- default is 1.8V, 1.8 + 0.3V = 2.1V set this to add up to your ram's voltage requirement.
PCI-E OverVoltage Control_ [+0.1V] <--- a little extra for stability
FSB OverVoltage Control___ [+0.1V] <--- a little extra for stability
(G)MCH OverVoltage Control [+0.1V] <--- a little extra for stability
CPU Voltage Control_______ [Per chart below] <--- very mild overvoltage so we can start playing soon
DANGER - Intel spec for Vcore absolute maximum is 1.55V. The BIOS will let you set a ridiculous high voltage, be careful. !!
Normal CPU Vcore 1.3250V but set it to 1.39v for now.
