Removing Heat-sinks
MSI used aluminum heatsink in this board with plastic cover over it and RGB LED installed inside. This reduces the total heatsink’s air contact surface area making overall heatsink more insufficient especially for VRM cooling. The base of heatsink is having thermal pad installed.
I/O cover is having a separate RGB LED pcb mounted..

Component Layout
Let’s now see what all components MSI have planned for this board.

1. 2. 11-phase digital power controlled via IR35201 is IR (International Rectifier) PWM Controller IC and IR3555M (Integrated PowIRstage) is a synchronous buck gate driver co-packed with a control MOSFET and a synchronous MOSFET with integrated Schottky diode with output current capability of 60A DC each.

3. Two 2-Phase digital memory power supply section

4. ASMedia ASM1074 a four downstream ports USB3.0 HUB Controller

5. 10. ASMedia ASM3142 a USB3.1 Controller

6. Intel i219v one Gigabit Ethernet controller chip.

7. nuvoTon NCT6795D SuperIO chip monitors temperatures, voltages and other key metrics for normal operation

8. MSI Audio is powered by Realtek ALC 1220 120dB SNR HD Audio - The ALC1220 is a high-performance multi-channel High Definition Audio Codec with up to 120dB SNR for crystal clear audio along with premium quality CHEMI-CON audio capacitors for a warmer sound and OP1652 op-amp as buffer.
A semi-transparent line on motherboard separates the whole audio section from the rest of the board in order to minimize interference. So licensing under Stereo mode produces high audio quality with excellent dynamic range.

RightMark Audio Analyzer (RMAA) suite is used for testing MSI High Definition audio against Asus Xonar U7 External Sound card. You can see clearly the difference between Noise level, dynamic rang and Total harmonic distortion percentage produced by MSI High Definition audio

RMAA Asus Xonar U7


9. Intel X299 Chipset

10. MSI uses two SPI chip labeled MXIC MX 2SL12873F a capacity of 128 Mb for storing UEFI BIOS.


Do It Yourself
For reviewing MSI X299 GAMING PRO Carbon AC motherboard, we were provided a sample Intel Core i7 7820X CPU along, which is a 8-Cores 16-Threads chip. To give a fare idea about the CPU performance we compared it with AMD Ryzen 7 1700 CPU which is also a 8-Cores 16-Threads chip.

AMD Ryzen is also a new platform so straight comparison was must. We tested both CPUs at stock settings and also at a 3.6GHz stable overclock.

Intel Test setup

CPU - Intel Core i7 7820X CPU
Board - MSI X299 GAMING PRO Carbon AC
RAM - 4 X 4GB Corsair DDR4
SSD - Kingston SV300 120GB
Cooler - CM MasterLiquid 280 Pro
PSU - Cooler Master V1200
Display - Acer S220HQL
OS - Windows 10

AMD Test setup

CPU - AMD Ryzen 7 1700
Board - MSI X370 GAMING PRO Carbon
SSD - Kingston SV300 120GB
Cooler - CM MasterLiquid 280 Pro
PSU - Cooler Master V1200
Display - Acer S220HQL
OS - Windows 10


Bundled Softwares



Power Consumption
Wattage reading as per displayed by APC Pro 1000VA (Model no. BR1000G-IN) UPS. Running Cinebench R15

Price to Performance
To get the Price to Performance score we took the Cinebench R15 scores of both CPUs at stock and divide them with price of both as listed on the publication date of this review. (i.e. i7-7820X = $605.50 and Ryzen 1700 = $309.99)

UPDATE : Also want to add that X299 motherboards are more expensive than X370 motherboards(even the more cheaper AMD B350 boards which support OC too). And don't forget all the RAID restriction crap from Intel on X299 boards.

  • RGB LED with headers
  • Nice Audio
  • AC WIFI onboard
  • Thermal shield for M.2
  • Great OC

  • Very small sized VRM heatsink


Intel X299 is the latest platform from Intel and MSI has done a good job with MSI X299 GAMING PRO Carbon AC motherboard in the look and performance section with tones of features and connectivity option to offer.
The audio, WIFI and overclocking capability could have made this board the best X299 option… but, as reported by our overclocker friend “der8auer”, all X299 boards have VRM heating/heatsink issues. So we tested but not as aggressive in loads and setting as der8auer did, but we kept all setting at stock provided by the manufacturer and concluded that the VRM heatsink on this MSI motherboard is very small in height when compared with other x299 brands motherboards and more the MSI VRM heatsink is having a plastic cover with RGB lighting further insulating the heat and above all NO back-plate on the VRM MOSFETs too. This results in a very high VRM temperature when compared with AORUS x299 and ASUS Stix x299 (i.e. approx 77C) running OCCT stress test at stock. Being the top of the line board and with a premium price tag, we could expect a bigger or better VRM heatsink with proper back plate from MSI.

Nice review! All the first wave of x299 boards seem to have compromised VRM cooling. Seems like board makers are more concerned about RGB bling than reliable operation. All of them throttle due to the VRM hitting 100+ temperatures.

Also could you please measure the power consumption with Prime small fft instead of CB15? The numbers should be a lot higher due to AVX.

And yes x299 boards have VRM issues, but few boards are having decent cooling solution too. Like Aorus X299 Gaming 7.. have a look.

Yes power consumption is way too high with Prime,, but that's an extreme torture for the board and i like to give a general idea about the power consumption.

Basically X299 platform is a total crap from Intel (like RAID key).. especially the last moment panic i9 CPU announcement. One can imagine the VRM situation with release of high end i9 CPUs.. i thing we may get to see X299 v2 soon.

^^ That looks like a solid heatsink design. What chips are they using for power delivery in the gigabyte? They cheapened out in the Ryzen boards where there was concern about overheating in the Gaming K7.

As for HCC i9 CPUs, I have my real doubts if any of these boards will survive the torture of an 18 core i9. This was an extremely rushed platform and it shows in everything.

I have these three boards and following are the VRM Section details.

MSI X299 uses IR35201 as controller and IR 3555M as MOSFET
AORUS X299 uses IR35204 as controller and IR 3556M as MOSFET
STRIX X299 uses DIGI+EPU ASP1405i (which is IR35201) as controller and IR 3555M as MOSFET

So far AORUS is the best x299 board I could find here.

Sharmaji ka thread after many days. Detailed as ever. Currently in office and will go through thread at night

is this for any build you have planned ? can you point me to the log if u put up a thread
