Default 8 phase vs 12 phase power around CPU socket

Hi this goes out to you scholars,

Could anyone explain to me in layman's terms what these tiny blocs are and what are their purpose. And what would be more preferable: 8*Rio R27 or 12*R40 ?
I tried google with a ''Rio R27'' search to no avail, and since I don't even know what the technical name of these thingies are, I couldn't specify my quest


Asus P5N32-E SLI

regarding those, all I could find is:
''8 phase EL-Capless power design
Reliable Power Supply and Longer Component Life
The 8-phase cap-less Power design demonstrates two hardcore commitments of ROG products: ultimate overclocking capability, and ultimate reliability. The 8-phase power design yields unparalleled superiority in the overclocking arena, while the EL cap-less design removes any worries of capacitor problems once and for all.''
source:Asus.com

now on this mobo they are twelve R40's (''Triple Quad Phase'' as Gigabyte marketing puts it)
Gigabyte GA-N680SLI-DQ6

''Quad-Triple Phase
An exclusive feature found only on GIGABYTE motherboards, this unique design incorporates Virtual 12 Power Phases to deliver steadier power and immediate current to the CPU and memory during heavy system workloads or overclocking. Additionally, Quad Triple Phase helps decrease the working temperatures, enhancing system stability and increasing component lifespan.''

Any light shed is appreciated

I will sit corrected if wrong but we started out with three phase then stepped up to six phase, Albitron and ASUS now offer boards with 8 phase, then along comes Gigabyte with 12 phase.
More phases equals smoother voltage and with the Albitron/Asus 8 phase better OCs and cooler running have been reported. Nothing that's world shattering but a tad. This 12 phase is very good marketing and may give a very slight improvement over 8 phase...Most likely.

This board will be looked at long and hard when my next build comes due.

The polymer caps used on this board are much more temperature tolerant than electrolytic caps...This is a good thing.

Thanks alot for the links CAD and Galvanized
I've registered over at Badcaps but never received the confirmation mail so I don't even know if you got your 15th referal
It is complicated for me to understand what they are saying over there, I do try my best learning bits and tits though. I wonder how I could find out if what one member suggested a 6 phase with 2 converters instead of 12 phases in Gigabyte 's mobos would be true or its effectiveness in comparison to 8 phased ones.

''R27'' on it means R27: 4.42kΩ, 1/16W, 1% (edit: bad link removed )

''R40'' = ?

Plantentanalog link does not work for me.

You can not register at badcaps with any free email service, this is to reduce spammers & bots. Use your IP's email service. There have been a couple changes over there and I can not find the member's list to look for Bipitri.

I have 16 referrals now, we are kind of in a race.

the link was indeed dead-ending so I removed it, it wasn't very important, lot of gibberish made by a Texas Instrument guy. that's where in the end I saw that R27 in the used components list of the article.
the good thing I learned is that higher number of Rxx doesn't mean necessarely higher ohm resistance. which I thought previously.

For badcaps: yeah I've seen it reject my regular hotmail, so I put my own family email domain and after acception they said I'd receive a mail which contained the account activation link but I never got it so I could not see the attachement sketch like you mentionned - even I doubt I'd get it anyways.
I tried registering again and it's even worse ==>can't re-use my email address nor Bipidri as nickname , they say that they're already in use
oh well if my mailbox tonight doesn't have the activation link, I'll use my university email account and user another username

I've seen your thread on Xtreemforums regarding the other Gigabyte mobo the 965-DQ6 I think. now I'm at university so not much time to look for reviews of that board, but I will for sure. You think its really a 12 phase ?

Give Topcat, the site Admin, a few days to get back to you. He is very slow at getting to his emails. If it said the name was being used when you tried to register again, it means...you are in the system. I looked at the member list and Bipidri is not showing yet.
PM me here this Saturday if you are not registered yet at badcaps and I will PM Topcat.

I am not a member at XtreamForums, so you are thinking of someone else.

I am not positive that this board is 12 phase but it is supposed to be. I do know there was a limited edition Albatron that was 12 phase.
6 or 8 phase works very well, 12 phase is more about marketing than raw performance gain. It will run cooler however.
