    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 listening 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

    9. Intel X299 Chipset

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


    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.

    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)


    • 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.
