What advantages does CPU VID Special Control give?

[Guest FZ1]

This is an old thread but has anyone further *proven* this? I seem to have better luck using the special but it could be some other factors.

Interesting stuff, I always thought CPU Special Vid was to give you voltages that are more finely tuned to what you need as opposed to the selectable voltages.

hum... I didn't think they were that high from looking in the OC database

 

I'm now running an XP-90, duing load my cpu temps are steady at 53c

 

No offense but that is just dumb. Why run your chip 24/7 at the abolute max temp? For all you know the temp is being measured wrong and your chip is slowly frying.

I played with overclocking at the same net voltage made up either by just core voltage or by lower core and using special on top.

 

There was not a single MHz of overclocking difference, and my DMM says I get what I say I want precisely.

 

I tested that with two CPUs, although I don't remember which ones, I think my CABYE Opteron and my Venice.

Interesting. I will give it a try and see if there is any difference

I wouldn't expect there to be a difference. Thanks.

shouldnt make much a diff at all, it would be the same as having a two settings to change the tenths and hundreths >shrug

Some MSI boards have this as well. My old Neo2 Plat's would make fine use of the feature.

 

I can't find it right now, but there is a post(MSI Forums?) postulating rather knowledgeably of

MB circuits in setting voltages and the advantages to "adding' in this fashion.

Interesting thread, I just had to try it myself . So far I'm dual priming @ 2.8ghz 1.425V x 107.2%.(approx. 1.53V) Normally I'm running at straight 1.55V, so maybe this can be a better setting?

I didn't see any diffrence abck when I was using my nf3 DFI.
