Question Please help me overclock an AM3/x6 new build

I have a very cool (temp-wise) case, decent 120mm fans, a CPU cooler that is about as good as a Thermalright Ultra 120, heatpiped MOSFET/NB, and a PSU that is somewhere between good and great (Antec EA-650)...

RAM installed is 2x2gb DDR3, I have no probs running it lower than 1600 if I have to...

Fresh install of Win7...

2x WD2500KS HDs in RAID 0, 128k block size


... I hit 3.6ghz earlier without really adjusting anything except CPU voltage... so now I'd really like to tweak the BIOS right and nail down a precise and aggressive overclock if I can.

Motherboard is an MSI 785GM-E65... reviews indicate that this motherboard and its sibling variants with the 5-phase switching voltage regulator overclock with great success...

CPU is an x6 1055t 125W PH-E0 (most PH-EO CPUs are 95W IIRC)...

My previous overclocking with AM2+/AM3 has been with Black Edition CPUs... I usually just did multiplier adjustments and CPU voltage adjustment in AMD Overdrive...

So here's what I need to know more about and adjust precisely (can I get some help?):
  • CPU VDD Voltage
  • CPU-NB VDD Voltage
  • CPU Voltage
  • CPU-NB Voltage
  • DRAM Voltage (I'll leave it at auto unless I decide to bring the RAM past 1600)
  • NB Voltage
  • HT Link Voltage
  • SB Voltage

Previous AMD mobo BIOSes only had CPU voltage adjustment, not this extra "CPU VDD" adjustment...

I want to try out 257 HTT @ 14x multi for 3.6ghz at first, and then move up to 3.8. Any assistance would be appreciated.

drop the memory to 1333, increase the NB voltage a tad and then start slowly increasing the htt slowly.

When you start increasing the htt, it will increase the ram speed and increasing the NB voltage helps keep that stable.

you can also try relaxing the timings on your ram for an easier htt overclock.
