GA-P67A-UD4-3 VS GA-z68-ud4-3?

post #1 of 8
Thread Starter 
I'm little confused, From reading and comparing the ga-p67a-ud4-b3 has better phase control then the ga-z68-ud4-b3?

http://ixbtlabs.com/articles3/mainbo...3-i68z-p1.html

"The impressive 16 phases are however managed by a single 4-phase PWM controller from Intersil that has its outputs doubled and doubled again. This solution has obviously been designed with marketing, not engineering in mind — just for the sake of that nice, high number

So what do you get then? An indicator showing how many CPU VRM phases are active. Guess why it only has four LEDs."

http://www.techpowerup.com/reviews/G...67A-UD4/5.html

"12 full phases for the CPU proper, with two additional phases for memory/System Agent control. Each of the 14 phases is terminated by a highly reflective metal-encased ferrite core choke, a small thing that really lends towards this board's high-end feel.

However, it's worth noting that there is only six LEDs, yet 12 phases. As noted earlier, this is due to the "Dual Engine" "

Go for the P67 version - the Z68 version doesn't even utilize the reasons why you would buy a Z68 motherboard (mainly on board video), takes away features (power phases) and is more expensive. Z68 is just another reason for manufactures to jack up the prices

From what I'm see ga-z68-ud4-b3 got some problems like turbo not working also in second link below one person said the boards run warmer. Just don't see any reason to buy z68 over p67.

I thought the Z68s have more power phases than the P67s?

Some do, but in general the mfgs are going to charge you more for less. The z68's cost more to make so the mfgs are cutting down on certain features to make up for the cost. On the board you were looking at they cut back on powerphases.

Technically anything over 12 phase pwm is overkill for sandy bridge.

Z68 has two more phases.

Mybe this is a better question. what is better phase control 4 doulbe to 8 double again to 16?

or 6 to 12?

I could careless about what other stuff comes with z68 but i'm seeing bad review at new egg saying the new z68 is a bad oc.

op: I would personally get the p67 unless you dont plan on buying a video card. Another advantage the z68 board has over the p67 is more sata ports. I was extremely dissapointed when gigabyte released there p67 boards with only 6 sata ports.

But the 12+2 power phase on the p67 is more than enough for some serious overclocking. I wouldnt get too hung up on the number of power phases. As long as it has 8 or more you will be just fine. Sandy bridge is way more efficient than previous generation chips so the increased number of phases is really just a marketing gimmick. Dont get me wrong, there are some people who benefit from all those extra phases, but those people are probably killing there chips doing suicide runs with ln2 and dice.
