Intel X299 (Socket 2066) VRM thread

Since Intel X299 boards are coming out I thought it would be a good idea to start a thread to discuss the VRM on these boards since they are HEDT CPUs.

That is more than doubling the output capability of the MOSFETs. The new Intersil ISL69138 true digital PWM controller from Intersil is in a 6+1 phase configuration. The last +1 is for the VCCSA and is on the far right side. Each power stage uses an ISL99227 Smart Power Stage, which is rated 60A, has internal current and temperature sensors, and offers double-sided cooling capacity (bottom through PCB and top through a metal area).

--> https://www.ocaholic.ch/modules/smar...id=4092&page=3 Warning: Spoiler! (Click to show)The MSI X299 Gaming Pro Carbon AC comes with a digital 8+2+2 phase power design. The CPU is backed up by eight phases and the memory receives stable current supply from 2 phases for four banks each. The CPU power design is controlled by an IR35201 dual-loop multi-phase buck controller, which has 8 output phases. Every single phase is backed up by an IOR 3555M driver from International Rectifier as well as one inductor. These IOR 3555M MOSFETs are capable of dealing with up to 60A output current per phase, which makes the power design of this board highly capable. On each side of the CPU socked the four DIMM slots are controlled by a 2-phase VRM controller from ROHM Semiconductor.

151-SX-E299-KR / EVGA X299 DARK "14 Phase Digital VRM" (8+8 pin power)
---> http://www.gamersnexus.net/news-pc/2...rk-micro-ftw-k Quote: EVGA has overhauled its power solution for the X299 DARK board, using an 8-phase core VRM with 1-phase VCCIO and 1-phase VSA. The VRM uses Intersil ISL69138 + ISL99227B MOSFETs for Vcore and VCCIN, with ISL69138 & ISL99140 for the VSA. International Rectifier is the choice supplier for VCCIO (IR35204 & IR3556), and ISL66133 & ISL99227 2-phase x2CH for VDDR. As for other changes, the X299 DARK motherboard uses EVGA’s newest BIOS – which has gone through a bit of an overhaul since X99.

---> http://www.gamersnexus.net/news-pc/2...rk-micro-ftw-k Quote: 8-phase Vcore. EVGA is running some of the same ISL parts for this motherboard as on the DARK board, opting for an 8-phase Vcore that is identical to the DARK, with a 1-phase VSA and 1-phase VCCIO, also identical to the DARK. Actually, the VDDR VRM is also the same as the DARK – this board uses the same VRM, just different visual and DIMM configurations for a lower cost market.

When things are sort of finalized I think I will try to make a table of some sort. OCN doesn't have wiki-style formatting for tables, unfortunately.

br0da currently has it in table form on hardwareluxx: https://www.hardwareluxx.de/communit...e-1167715.html

The TL;DR version is don't buy MSI's x299 Tomahawk, SLI PLUS , or Raider : a VRM monoblock can't help with lower efficiency mosfets with no built-in thermal monitoring heating up on the back of motherboard. IR3555 / ISL99227B have built-in thermal monitoring and protections such as OCP/OVP.

Thanks for the thread!
Is there still only one input voltage needed for LGA2066 CPUs?

First reviews with VRM info I found:
MSI X299 Gaming Pro Carbon AC:

Gigabyte Aorus X299 Gaming 3:

I see VCCIN/CPU input voltage, V_Core , CPU cache, Uncore, VCCIO , System Agent , PCH. Probably CPU is only use for CPU phases.

Looks like integrated voltage regulators like those from Haswell, doesn't it?
Just ~1.8V VCCIN from the bucks on the motherboard and all those different voltages get generated internally.

Edit: Ah, it was already exactly the same for Haswell-E, nevermind.

(That's for Haswell-E)

Check this Korean review out:

It has a lot of hires pics of the 3 X299 mainboard's vrm (Asus X299 A Prime, Rog Strix and MSI X299 PRO Gaming Carbon AC)

So yeah, looks like 8 phases for the both A Prime and Strix (with 8 IR3555) and sharing the same (Asus rebranded?) pwm.
Same IR3555M (11) and an IR35201 pwm for the MSI Gaming Pro Carbon.

Asrock options look very generous

X299E-ITX AC (http://www.tweaktown.com/news/57771/asrock-x299e-itx-ac-up-12c-24t-cpu-power-form/index.html) --- 7 phases on daughter board

Power isn't on the daughter board, it's actually a daughter board for the six sata ports, USB 3 internal header and something else (like USB 2.0 front header)

Nevermind

They're not, zoom in, you can see the white silk screen squares on the motherboard for the chokes.

The daughter board is exclusively for SATA / USB. Why else would've they made it removable?

The heatsink for the VRM serves as a bracket for this daughter board so it stays in place too.

In the picture, you can see the heatsink goes all the way to the other side, so nothing can be soldered from the mainboard, onto the daughterboard.




See that gap under the daughterboard?
