Vcore supplied to proc


Recommended Posts

Hi guys. I've used c n q / rmclock with without any glitch ( even prime stable at 1.16G @ 0.85v ). Now, here is my situation :


bios setting :

without rmclock :

CPU VID : 1.375

Special CPU VID : 104%

Full Stable clock : 2.9G @ 1.41v



with rmclock :


Special CPU VID : 104%

RMClock profile : Maximal Performance { 1.4v }

Full Stable clock : 2.9G


I've been asking around about rmclock about the vcore supplied to the proc when setting 1.4v. And now, i'm really confuse. Which one of this applies :


a) Vcore = CPU VID + [ CPu VID * 104%] = 1.4v




B) Vcore = 1.4v + [ CPU VID * 104%], which result will be 1.456v.


here's the value shown in software reading :

MBM [ dfi street custom setting ] = 1.41v

ITE Smartguardian = 1.41v

Everest = 1.41v

CPU-Z = 1.41v

AMD Power Monitor = 1.4v


Here's what the author of rmclok reply in their forum

It means that, with your settings, your motherboard applies extra 4% over-voltage to the CPU VID requested. This way, you'll get Vcore = 1.4*1.04 = 1.456V when a 1.4V VID is requested. The values obtained from sensors and displayed by monitoring software are inexact by their nature and hardly can reveal such a tiny Vcore difference


I thought, MBM will show the "result of combined CPU VID and Special VID control" as the author does re-labelled it as "cpu+vid" and smartguradian is showing the vcore supplied to the proc as by using manual vcore control, it does show the correct vcore combination of both.


Hope someone can help me here.


thanks and sorry for my bad english.

I do not use any Windows based utility to overclock my rig. All o/c settings should be applied directly through BIOS. I'm not familiar with rmclock, but your actual voltage should be cpu vid * special cpu vid = actual voltage.


As an example;


1.375 cpu vid * 104% special cpu vid = 1.43 vcore


While SG and MBM5 are both excellent software utilities, I always trust my BIOS voltage readings more than any other Windows based software utility. If in serious doubt you can always check your actual voltage with a digital multimeter.

1.375 cpu vid * 104% special cpu vid = 1.43 vcore --> yeah... mine droop 0.02v. it's a minor problem to me.


Well, it's really nice to have 0.85v @ 1.16G just for browsing the web, right? and max speed during games / benching. RMclock does this on the fly and beat cnq with 4x multiplier at lower vcore ( 1.1v is min w/ cnq ) ( 0.8v is min for rmclock ). measuring the vcore + vid is using the same spot as here shown here by mr. soundx98, right?




or is it just for vcore ( without the special VID )?

Software OC progs are only to look what might be possible without constant rebooting the system, but you can f**k up your system in a second. :eek:

They are often used to produce nice screenshots to let other people believe you reached a very high OC.:rolleyes:

It ain't stable at all.

What's more fun than spending a weekend long finetuning settings, running mem, pi & prime tests. :)
