ROG Zenith Extreme Alpha X399 ROG Rampage VI Omega X299

FLASH INFO

As expected, ASUS just releases its latest ROG series “refresh” for high-end Intel and AMD CPUs.

They carry these code-names preceding the motherboard names:

  • Alpha (AMD powered motherboards)
  • Omega (Intel powered motherboards)

What changed ?

Not much. But in both cases, ASUS has given a real focus to keeping the VRM cooler, longer. Other than this, we are dealing with almost identical PCBs and almost identical components. Let’s dig a little deeper:

ROG Zenith Extreme Alpha: AMD X399 for Ryzen Threadripper

At first glance, there are no obvious changes between the ROG Zenith Extreme Alpha and its predecessor, the  ROG Zenith Extreme .

But one thing which did make me beam is the VRM cooling system. We can see not one, but 2 VRM fans mounted right on top of the side (8) phases.

The Zenith Extreme has somewhat of a over heating problem as it stands. The Alpha refresh seems to want to fix that!

No more fan vent on the back IO (good and wise move). That does translate in a second Lan plug! We now have a 1 Gigabit as well as an Aquantia 10 Gigabit Ethernet plug! No more external PCie to enjoy a 10 Gig Lan :).

But after reviewing the Prime X299 Deluxe II a couple weeks ago, I was expecting to see a “dual-thunderbolt 3” feature, which made such an impression on me. Indeed, I am a bit disappointed about that.

.

Power delivery wise, we got a 8 phase VRM delivered by 16 power stages. With the upgraded VRM cooling system, I do not expect serious over heating, even when over clocking the gargantuesc 2990WX.

We got premium 5000 hours life-span chokes and the expensive (and rare) IR3555 PowerIRSTAGE ICs which is great news for Overclokers.

Same remarks apply as in the Zenith Extreme Alpha.

The Rampage VI and Rampage VI Omega are, in essence the same board, but I am equally happy to see the upgraded side VRM Heat sink. We have 2 fans directly mounted on the 10  power stages. Again, great move in terms of cooling and heat dissipation!

.

.

The Back IO is identical to the Rampage VI’, save the disappearance of the 802.11AD Wi-Fi simple antenna, which did not survive on the Zenith Extreme Alpha either.

.

They will be available this month in major retailers across the globe, so you won’t have to wait too long.
