MSI K8N NEO2 Platinium owners, plz look here !

There's 2 options in the Bios who seems to both do the same thing (changing the Vcore).

One is called CPU VID (let you select a value or default Startup) and the other is CPU Vcore (option are By CPU VID or over 3.3%-5%....).

To be honnest I've been "playing" with both when I do some OC testing....

Anyone know the difference between to two?

Which one should I use?

CPU vcore works with the numbers u set in CPU VID

mine is set at 1.45 +3.3%, so its something around 1.49 max

The CPU VID percentages are the % overvolt on the voltage value you had selected from the CPU VID .. AKA 1.5v plus say 10% or 8.3%, this will add more voltage, basically 10% or 8.3% more to what you have chosen in the CPU VID

be aware that the motherboard under volts so you will not get what is stated in the BIOS .. use CPU-Z to check for accurate voltage .. 😉

Yep..

I find myself booting and rebooting sometimes just to check voltages! 😛

Check your LOAD voltages too!

But you none of you explain if there's any difference for changing the Voltage..by using one of the two option..CPU VID or Vcore...I mean..from the look of it...the end result is exactly the same.

changing just the cpu vid wont do much, even if you set it at 1.55 it will really be 1.44 max, if you want higher voltages use the vcore along with the cpu vid

Are you sure of that because when I was not OC my CPU i found that I could lower me Vcore ( with the CPU VID ) at 1.125volt and it was stable...( It was really 1.125v..every program I used..like Cpuz, Corecenter,etc.. did tell me 1.125v ...)

 

[pacho108]

lowering the cpu vid of course works, what i meant is that rising the cpu vid for ocing it maxes out at 1.4something even if you set it at 1.55

you can see that there are no options for lowering the voltage in the cpu vcore setting, only for rising, it will set your voltage 3.3% - 10% over the 1.125 you set it at in the cpu vid, you can reach over 1.6 which is not an option in cpu vid.

So you're saying that I can't go higher than 1.4 something just by using CPU VID...Ok thx...but..in my case...I still have one question...I know as a fact that I can reach 1.45v or so with both options...since both can reach it...its there any difference between the two? is one more stable?

I ask because I know my 3200 winchester can run stable at 2.4ghz and 1.45v...its it better to set it with CPU VID or the Vcore +3.3%?

BTW...CentralProcessingUnit(CPU)..but do you know what the VID stand for?

 

[pacho108]

if you can reach 1.45 with just the cpu vid leave it there, if not set the cpu vid at 1.35 and the cpu vcore at 8.3%, you will get 1.46, this is by calculating because the board undervolts and in my case somtimes overvolts, set it then check it with cpuz, if you didnt get what you wanted change it until so

for the VID question i dont know i just got this board a month ago

 

[Furen]

I use % voltage modifiers because they work with cool and quiet (basically they add that percentage to whatever vid the CPU sets).

 

[2kfire]

Basically, the Vcore +XX% just adds that much to whatever the CPU VID is set at. So, if you set CPU VID to startup and your cpu's voltage is 1.4, it will run at 1.4. If you set CPU VID to 'startup' and then Vcore +10%, it SHOULD run at 1.54 (1.4+10%, but it doesn't, because like others said, board undervolts 😕 ). Another example, if you set CPU VID to 1.2v, and Vcore +5%, it SHOULD run at 1.26v. As to which one is better, I think Vcore +XX% would be better, because what Furen said about CnQ
