4+1 phase vs 8+2 phase - Page 3

post #21 of 26
It is all about clean power with ripple suppression than the number of phases.

sounds unlikely. it is probably 12+3+4 or something like that. since most boards are just split 4+1 phase designs (4+1 X 3 = 12+3, and then the other 4 is for the IGP or memory or something)

got a link?

I would think that any 990fx board would have more than sufficient power delivery - it's AMD's high end chipset - and the FX boards are normally very good quality.

The 990 chipset has nothing to do with the VRM circuit per se, which supplies power to the CPU. The UD7 uses an 8+2 split phase VRM circuit, which has worked fine. Any AM3+ mobo approved for FX CPUs will have the minimum 125w requirement to run any of these CPUs. How far you can run beyond the 125w minimum is open to discussion based on testing.

You (AMD4ME) love throwing your balls around here I can see, doubting everything without "proper testing" as if you are even qualified to determine what a proper testing might entail.
I'll retract my rudeness when you provide some evidence of a 990x or fx board with an inferior VRM setup.
The guy asked if the 990FX UD7 would be sufficient. My answer is correct in saying that any 990 board should almost guarantee a very good overclock (depending on the other components of course) which means that the power delivery obviously isn't crap and really doesn't warrant further testing as I've not seen a single instance of a 990 board with power delivery issues.

I have no idea why you are responding in such a hostile manner but my post had NOTHING to do with your comment and was a general response on the subject of VRMs and specifically the Gigabyte UD-7 which I posted a link to showing it was an 8+2 split phase design VRM.

You're reading WAY too much into my posts and your conclusions and over-reaction are totally inappropriate.

The bottom line is no one knows what the VRM limitations are on any mobo without actually testing it. It's pure speculation without actual testing. Reality doesn't change regardless of your opinion or assertions. No where did I state that ANY mobo was unfit for OC'ing including the UD-7. My comment was that we don't know what the limit IS when OCing until you actually test and see.

If you aren't receptive to other POVs in a public forum then you might want to stop reading threads as you're gonna be very frustrated when folks don't take your subjective assertions as being the Gospel. In the engineering community we don't guess, we perform objective testing to determine reality.
