if ur playin with cpu multi only, increase vcore, if u play w/ htt oc, it depends > vhtt, v cpu-nb, vdimm mite involved as well if so.

from my bios which 1 is vcore??
the only voltage i can see is this...

CPU VDD voltage

or

CPU-NB VDD voltage

or

CPU voltage

n got summore

im using msi 790fx-gd70

cpu voltage if i remember correctly...

how about this source?
http://www.ocztechnologyforum.com/forum/sh...ll=1#post380767
it say cpu vdd voltage is the main thing to touch instead of cpu voltage?
i also confused.

thanks for pointin out bro, it's been a while since i last use d board. come to think of it, one has d options to choose either to play w vid only or leave vid untouched & play w/ d offsets. ofcoz, playin w/ vid is more direct but if offsets can be smaller decimal, why not rite?

so which i shud i play wit....lol

for a start u can just play w/ cpu-vid which is cpu-vdd in this case.

really?...ok thanks

hmm, because i m not clear how cpu vdd voltage and cpu voltage work.
these 2 voltage also direct contribute to vcore?
it is have to adjust either one? or need to adjust both?
if these 2 voltage adjusted to different value, then it will take which one to be vcore?

both cpu vdd voltage(vid) n cpu voltage(vcore) i try dy...
when i increase either 1 to 1.5v...then only my proc stable at 4gz...
below 1.5=not stable...1.5v is it too high for voltage tweaking??

ok..lemme explain

using the term in the ss u posted.

cpu-vdd is the base vcore that the processor control how much to take it.
the real term for this (that amd uses) is cpu-vid as mention by ah khoo
the real value is like 1.35v , 1.375v like that (depends on proc, BE can go 1.55v, non-BE is lower)

for cpu-voltage, is mobo controlled.
the real value is 0.025 , 0.05 (depends on mobo how fine the value)
but for easy viewing, MSI make the value 1.36v ,1.37v.

so the vcore we seeing is cpu-vdd + cpu- voltage.

depends on ur proc.. but for 4ghz, 1.5v is not that high.. but the temp and the mobo will decide it is high or not
why i said that, cuz 4ghz 1.5v i have seen many. like that is common vcore to get 4ghz.
but ur temp, i donno. if like >60, the vcore is high..
and if ur mobo not strong enough, 1.5v x4 is high.. get me sir?

i see.
means the cpu vdd voltage on auto is the stock vcore of the cpu lo.
and cpu voltage is the offset voltage that add to the cpu stock vcore.
right?

let say an amd cpu come with 1.35v stock vcore.
if want to increase the vcore to 1.4v, have 2 options:
1) change cpu vdd voltage to 1.4v from auto, leave cpu voltage on auto (+0.00v).
2) leave cpu vdd voltage on auto (1.35v), change cpu voltage to +0.05v (equivalent to 1.4v on the msi board?)
or even
3) change the cpu vdd voltage to 1.3v from auto, and change the cpu voltage to +0.1v (equivalent to 1.45v on the msi board?)
is that like this?

1.yes
2. yes
3. it should be 1.4v

but msi not showing the cpu-voltage as offset. shown as real value. so will be user frenly,
but it is.

example:
cpu-vdd = 1.35
and u add one notch of cpu voltage, it will starts with 1.36v (let say the increment is 0.001v im fogot the real value already)

if cpu-vdd =1.50
u add one notch of cpu- voltage, it will starts with 1.51v

i see. get the idea already.

I heard something dropping...

what is that?

AMD dropping confusing brand names for their BD/BC proc got la

thuban price dropping.. but in dilemma to get 1 or not cuz BD is coming..

guys, instead of usin 3dmark 06 cpu test, can we consider cinebench cpu test? free edition 3dmark 06 cpu test requires us to complete d whole test in order to get d score right? correct me if i'm wrong... it's not nice to use ahem version in any compy, no?

i'm finalizin d thread witihin today, hopefully it can be up tmr... not feelin too well coz too much junkies during cny...

Hmmm not sure if an athlon II vs phenom II on same clock will produce same result on that benchie
Would a L3 cacheless cpu's be a bit slower?
