First things first I guess, here are my system specs
CPU: AMD 1090t
Mobo: MSI 890gxm-g65
RAM: 8GB (4x2GB) crucial ballistix tracer (red)
GPU: 2x HD5770 (OC to 960/1420 both cards)
PSU: Silverstone ST1000
Case: Antec mini P180
Cooler: Corsair H70
My goal is to hit 4.2Ghz, 4.0 is ok, but 4.2 is better
I have a few questions however
1.) What exactly are all of these BIOS voltage settings
CPU-VDD
CPU-NB VDD
CPU Voltage
CPU-NB Voltage
NB Voltage
DRAM Voltage
Obviously DRAM is the memory, my main confusion is the CPU-VDD/CPU-NB VDD and the CPU voltage/CPU-NB voltage.
I would think the CPU voltage would be Vcore, at auto it is like 1.3 or so, way too high, the CPU-VDD however seems to have the right number for Vcore, but that leaves me to wonder, wtf is CPU voltage for.
2.) Which voltage reading do I trust?
I have started to OC a little bit with just the multiplier (at 4.0 Ghz right now) raising the CPU-VDD voltage, but what I set that voltage to and what CPU-z reads are way different.
I had it at 4.2Ghz with my CPU VDD at 1.45, but CPU-z read 1.560 (whoa!!) so I shut that down immediately and scaled back to 1.4 and 4.0Ghz which nets me a CPU-z voltage of 1.480. So my question is, do I trust CPU-z and figure I cannot do 4.2Ghz reliably (24/7 clock) or do I trust my BIOS settings? For reference my temp in AOD did not pass 45C at the 4.2 setting, it peaks around 35 when everything in BIOS was at AUTO.
I want to get this voltage stuff figured out before I end up frying my chip, I plan on making sure it will be stable at 4.2Ghz then figuring out what the highest Bus speed and HTT speeds I can get will be
