Sorry about slow reply.

X99-Deluxe II is using:
8x IR IR3556 PowIRstage (50A, so 400A total)
IR 3580 is the PWM; not 100% certain on that, as Asus likes to use its own custom Digi+

It's a slight downgrade versus the IR3550M x8 on the Deluxe 1, which was 8x60A = 480A. Not a huge deal. For now, it's more than adequate.

It is looking though that Asus is reserving top tier VRM for the Rampage V Extreme Edition 10.

Datasheet for IR3556:

And if you want to compare IR 3550:

Doublers: Intersil ISL6611A
Memory PWMs: UPI Semiconductor UP1674

30A x 12 = 360A as per de-rating curve
At 125C, it does drop a bit though, but still adequate

Datasheet for VRM
https://www.fairchildsemi.com/products/discretes/fets/mosfets/FDMS3668S.html

Still more than adequate. It's not as powerful as the top tier boards and is basically half of what the X99 OC Formula offers, but it's still a good value considering the price of the board. thumb.gif

Unless you are doing something crazy, it should be adequate.

I was thinking of getting the Deluxe 2, but wondering if the downgrade means I should go for the Deluxe 1?

Any info about the x99 Rog Strix?! I tend to hate the way the Rampage looks (plus it's crazy expensive). I want a board that's great for overclocking, but boards designed for overclocking tend to look way too gamery for my tastes. The Deluxe 2 even looks a bit too gamery for my tastes but at least it's somewhat toned down. The Rog Strix looks pretty toned down too so wondering if that has a better VRM than Deluxe 2?!

Nope, strix is worse on the vrm. Iirc it uses onsemi mosfets like the cheaper boarda.
post #137 of 141
Very good to know. I'll probably end up going with the Deluxe ii. The only thing holding me back is it's color scheme. I'd prefer an all black board like the godlike carbon from MSI but the price tag on that board is nuts, especially considering they use killer LAN which doesn't play nice with Linux (my machine will be dual boot) and the deluxe ii comes with a Thunderbolt card and Intel WIFI, both of which I will use in my setup frequently.

I know this goes a bit outside of this discussion topic (VRM Design) but do you guys know if there's any use to the IO "shroud" (on Asus x99 boards, the white plastic cover on left side). Considering removing it completely if I get the deluxe ii.

I get the same temperatures on my VRM. This VRMs are rated fot very hight temperatures, no problem there. Besides, i find sabertooth a great overclocker and thermal control on them are great! No worries there!

Worse than nothing. It actually runs hotter with the thermal armor:
http://techreport.com/review/20863/asus-sabertooth-p67-motherboard/2
Quote:
Armed with Thermal Radar, we set out to test the usefulness of the Sabertooth's outer skin. We tested the board on an open test bench and in an Cooler Master Cosmos enclosure with the CPU strapped to a tower-style Intel cooler and a stock unit that blows toward the socket. Asus wasn't able to provide us with an assistant fan by press time, so we had to test without—that is, after all, how the board is sold.

Overall, Thermal Armor looks like a very bad idea. When we subjected all the configurations to a combined CPU and GPU load, component temperatures were hotter with the armor in place than with it removed. The differences weren't insignificant, either. Component temperatures were more than 10°C higher when the armor was used in conjunction with the stock cooler, I suspect because the air being blown into the shroud had already been warmed by the CPU heatsink. This was true not only on an open test bench, but also in our tower enclosure.

Letting the system idle produced better results, at least when the Sabertooth was run in a case with the stock Intel cooler. In that config, and only when idle, component temperatures were 3-4°C cooler with the armor installed. Success! Sadly, this advantage disappeared when we switched to a tower cooler or an open test bench.

We contacted Asus about our results, and the company said the effectiveness of Thermal Armor will depend on one's case, cooling, and system configuration. I'm a little dubious that lower temperatures can be achieved when the airflow is coming from a CPU cooler whose heatsink is being warmed by a loaded-up processor, though. I'm also discouraged that component temperatures were so much higher with what amounted to a pretty standard system configuration. For a lot of folks, Thermal Armor may do more harm than good.

Watercooling would be even worse because there's no fan on the CPU - period. The fans are of course on the radiators. Pancake style fans are the only types of fans that could benefit from the thermal armor.
