But it's interesting to see just how out of wack these values are from bios (f6a) to ET6

CPU Vcore - 1.44375v affected by vdroop to 1.408v in ET6 and under load drops to 1.376v lowest
CPU Termination - this value changes correctly
CPU PLL - this value changes correctly
CPU Reference - 800 in bios shows 720 in ET6
CPU Reference2 - 876 in bios shows 800 in ET6
MCH Core - this value changes correctly
MCH Reference - 736 in bios shows 660 in ET6
MCH/DRAM Ref - 910 in bios shows 760 in ET6
ICH I/O - this value changes correctly
ICH Core - this value changes correctly
DRAM Voltage - this value changes correctly
DRAM Termination - 910 in bios shows 760 in ET6
Channel A Reference - 910 in bios shows 760 in ET6
Channel B Reference - 910 in bios shows 760 in ET6

I had vMCH at 1.380V but had to move it up a notch to 1.400V.
CPU CLock 900mV
PCI CLOck 900mV
CPU CLocK 50ps (100 works 2)
MCH cLOck 0ps
can confirm same ET6 misreports some values

First time with P45 chipset board, GA-EP45 Extreme !

Managed Super Pi 1M bench run @7x564FSB 4-4-4-15 but needed PL10 and 2.48v to do it ! Not fully stable as only had EP45 Extreme setup less than 48hrs ago

Everest Bandwidth & Chipset
Seems that read memory bandwidth and latency are quite low for 564Mhz 4-4-4-15 memory clocks and timings but write and copy bandwidth look decent. Probably due to the loosened Static tRead (what DFI/Asus users would of known as tRD or performance level) of around 10. Gigabyte Easytune6 utility misreports, the values set in bios for CPU Reference, CPU Reference2 and MCH Reference. Easytune6 reports the default normal values instead they should be 0.853, 0.868 and 0.828 respectively.
