(tightest you can go with memory can handle it is around 2-3 but you may require more vdimm memory and/or NB volts)
---Row Refesh Cycle Time: 42
(tightest you can go with memory can handle it is around 25-30 but you may require more vdimm memory and/or NB volts - 35 is a safe compromise from 42. Some memory at very high clocks just can't handle value of 25 regardless of NB volts/memory voltage)
---Write Recovery Time: 10
(tightest you can go with memory can handle it is around 3-4 but you may require more vdimm memory and/or NB volts - loosening the values (raising value) - will allow more memory stability or higher memory clock at expense of memory bandwidth performance)
---Write to Read Delay: 10
(tightest you can go with memory can handle it is around 3-4 but you may require more vdimm memory and/or NB volts - loosening the values (raising value) - will allow more memory stability or higher memory clock at expense of memory bandwidth performance)
---Read to Precharge Time: 10
(tightest you can go with memory can handle it is around 2-3 but you may require ALOT more vdimm memory and/or NB volts - usual value of 8 to 10 will give nice boost at decent voltages)
DRAM Static Read Control: AUTO
(Related to what you see in Memset's Performance Level. Related to tRD value, when enabled it tightens the Performance level (tRD) boosting memory bandwidth/system performance. However, it's predefined AUTO vs Enabled value depends on your memory's cpu:mem divider used i.e. at 2:3 divider vs 1:1 divider, AUTO or Enabled set value for performance level may differ. Use trial and error to find you stable mark. i.e. boot into windows with AUTO set and look at when Memset shows for Performance level. Then reboot into bios set Enabled - test with Memtest86 v1.70 in DOS to make sure no errors and then and boot into windows to see what Memset shows for Performance level - it should be tighter (lower value). If memory can't handle tighter value then you may get system freezes in windows or BSOD or inability to boot system. So you can try raising any combination of these voltages - vdimm memory voltage, NB volts and if high FSB is in play also vFSB, SB Volts to see if they help) NOTE: Static Read Control and Transaction Booster can not both be Enabled at the same time especially at <500FSB on cpu. Some bios have a strap change at >500FSB which means tRD (performance level is loosened by default at >500FSB) which may allow both options to be enabled or allow either one of the options to be enabled where you might not have been able to enable it at <500FSB).
Transaction Booster: AUTO/Enabled/Disabled
(related to Static Read control in that it effects Performance level/tRD displayed in Memset as well - when enabled you have levels to choose higher the level the tighter the tRD (performance level) is and more performance. You have more control of the performance level with this setting that Static Read control. Disabled values loosen the tRD (performance level from defined default AUTO value can be used for stability or higher memory clocks)

CPU Spread Spectrum: Disabled
(leave Disabled when oc'ing)
PCIE Spread Spectrum: Disabled

CPU Voltage: AUTO
CPU Voltage Reference: AUTO
(can leave AUTO only needed to tweak some more FSB out of a cpu i.e. quad core)
Loadline Calibration: AUTO or Enabled
(reduce vcore droop under cpu load)
FSB Termination Voltage: AUTO
(related to cpu FSB - each cpu will respond differently to this voltage so trial and error testing. I'd keep it <1.4v for 24/7)
North Bridge Voltage: AUTO
(higher NB volts allows tightening and higher memory clocks as well as higher max cpu FSB and tighter subtiming handling)
North Bridge Reference: AUTO (can leave AUTO only needed to tweak some more FSB out of a cpu i.e. quad core)
DRAM Voltage: 2.10v
-DDRII Channel A Ref Voltage: AUTO
(fine tuning memory clock stability - leaving AUTO should work for most folks)
-DDRII Channel B Ref Voltage: AUTO
(fine tuning memory clock stability - leaving AUTO should work for most folks)
-DDRII Controller Ref Voltage: AUTO
(fine tuning memory clock stability - leaving AUTO should work for most folks)
South Bridge Voltage: AUTO
(higher SB volts may help memory clocking/CPU FSB and if you use high end video cards a slightly higher SB volt may help memory/system stability - usually i set it at 1.05-1.125v)
PLL Voltage: AUTO
(Clock generator voltage - can leave AUTO only needed to tweak some more FSB out of a cpu i.e. quad core. Up to 1.7-1.8v for benching is okay but for 24/7 keep it as close to 1.5v as possible (AUTO is dangerous as it can set itself to 1.8v! - too high can kill a cpu faster than vcore voltage could)
