you have a DFI UT 790FX M2R? does your bios have "cpu vid special add"?
Yes.
And Vcore as well.

Yea I had heard that, I tend to stay away from beta bios's, I take it you aren't having any issues with it then?
my bios doesn't have a vcore optionYes.
And Vcore as well.
i guess CPU VID & CPU VID Special Add are the same. e.g if the default voltage is 1.35v and u wanna up to 1.425v, u'll use CPU VID Special Add and put +75.0mv. but what i don't understand is why as the M2R got both.I have both,
CPU VID
CPU VID Special Add
in my bios, I am using an M2R though, not the M2RSH, with the latest official bios, which is 01/12/2008 I believe.
dfi site says the LANPARTY UT M2R as sb600. so how is that the very top.Yes, you do, as far as I know. I haven't done so yet though as I haven't overclocked my chip yet. i am not sure about the special add bit though to be honest, maybe it takes it past the cut off point for the VID control, to achieve even higher voltage for extreme overclocking with water or phase change cooling or something, I'm not sure, just a theory.
Remember one thing though, the M2R is a Lanparty UT board, the M2RS/H is a Lanparty DK board, which is actually lower down the DFI line of boards. The UT is the very top, the DK is a notch down. So that might play a part in this, I know my M2R came with duel Gigabit LAN ports and a Transpiper cooler attachment, it also has a full heatpipe cooler going from the mosfets>NR>SR. The M2RS/H does not have it extending to the SR.
The M2R also has a 7 phase (5+2) power setup, the M2RS/H has 5 I believe (4+1) ..and the M2R has an extra PCI-E x4 slot than the M2RS/H does not have. So it is not unreasonble to assume that it has more options in the bios too.
from that LANPARTY UT M2R to the LANPARTY DK M2RSH board i can only see 2 differents. the 2 lan's and the lower sb.It was the top, for some reason DFI did not make the 790FSB M2RS/H a full UT board. While they may be the 'replacements' for it in most regards, they are not actually 100% swap out replacements, because they are DK boards not UT's. Maybe they are saving the next full UT for the AM3 platform.
mine idles at 25c now and 35-37c underload...
ThermalRight SI-120.Which cooler?

do u use CPU VID to up your voltage?
my CPU VID Special Add table goes in 25.0mv's -/+, which is small enough. so maybe that why my bios doesn't need CPU VID.I use CPU VID most of the time but if you want ultra fine tuning of volts then you use CPU VID Special Add in combination of CPU VID as the CPU VID Special Add has a different voltage table.
Also as some has said to get the most possible voltage output from the board will need both CPU VID and CPU VID Special Add.

ohhhh your CPU VID Special Add table is different.PWM Control: Enable/Disable to open Voltage control function
CPU VID Control range: 0.44375V~1.600V, Default AUTO by detecting CPU.
CPU VID Special Add: 100.16%~121.25% plus on CPU voltage.
CPU NB Voltage Control range: 0.44375V~1.600V, Default AUTO by detecting CPU.
CPU NB VID Special Add: 103.57%~124.99% plus on CPU voltage.
DRAM Voltage range: 1.39V~2.76.00V
SB PLL 1.2V Voltage range: 1.20V~1.50V, South bridge working voltage.
NB Core Voltage: 1.20V~1.50V, CPU to NB bus voltage
NB PCIE Voltage: 1.20V~1.50V, CPU to NB bus voltage
NB HT Voltage: 0.98V~1.50V, CPU to NB bus voltage
ohhhh your CPU VID Special Add table is different.
mine is auto, +25.0mv ~ +775.0mv, -25.0 ~ -800.0mv. so maybe that why my bios doesn't need CPU VID.
i guess thats why i have a higher CPU VID Special Add range? also mine are in mv values not %Your max volts possible to the CPU will be determined by its default VID.
With the MR2 bios with CPU VID Control range: 0.44375V~1.600V, Default AUTO by detecting CPU.
CPU VID Special Add: 100.16%~121.25% plus on CPU voltage.
The Max volts possible will not be restricted by the default CPU voltage.
With max Volts of 1.6 + 121.25%= 1.94 Volts.
