By default MSI uses a 500 KHz CPU switching frequency for both boards and Buildzoid calculates that at 1.2v with a 200A draw the Gaming Edge VRM puts out 46 watts of heat and that would explain why these boards run so hot given a 3950X will pull around 170-190A with PBO enabled. Meanwhile Buildzoid also calculates that the new Tomahawk board will generate just 17 watts of heat under the exact same conditions. That's over a 60% reduction in thermal output. I am absolutely elated by the fact the Tomahawk is not loaded with LEDs but the placement of the few LEDs the board does have I don’t like, MSI for reasons that I’m quite sure absolutely nobody can fathom still insist on placing the LEDs on the rear of the board at the edge near the DIMM banks, this position someone clearly has a real turn on for heh... lights, turn on and off, yes, another intended pun. The most logical place to put LEDs if you are going to use them is somewhere you can’t easily illuminate yourself if you want to, like as part of the shroud over the rear IO like on the X470 GPC (you’re going to see this board referenced a lot). Finally coming to the M.2 slots I am pleased to see both of them have a heatsink, you either include heatsinks for every M.2 slot you have on the board or don’t include any there is no halfway house here because people like to match things like that up. Set Core Power Free: Extended Heatsink Design, Core Boost, Digital PWM IC, 8+4 pin CPU power connectors, GameBoost, DDR4 Boost MSI could have done better with the Tomahawk without increasing production costs, likely reducing them in fact, with only minor changes. I didn't really detail it too much but I would have made a second non WIFI SKU Tomahawk that had the following; And as for the VRMs, this is a top priority for me but what I didn't realise was that some B550 boards rival this board on VRMs (B550 Aorus Master is actually better).

So the question becomes do you really want that 2.5G LAN and WIFI all things considered? I’m going to bet that at this level the large majority of you are going to answer “no” to that meaning MSI could have gone with something like the Realtek L8200A which is a perfectly acceptable option and ditched the WIFI entirely to allow for improvements in much more important areas, like with the audio. Now for the final part of this peoples review it is time to see how the X570 Tomahawk OCs and to see if there are any firmware bugs to report on. AUDIO BOOST: Reward your ears with studio grade sound quality for the most immersive gaming experience I do like that the Tomahawk doesn’t light up like Mardi-Grass if you want LED lighting that’s what LED fans, strips, cathode lights, etc are for and you can replace those when they start to dim or become faulty no such ability with mainboards incorporating lighting. I don’t like that despite all of the effects you can choose from that you can’t customise the colour on all of them which quite severely affects the entire point of having LEDs on the board to begin with.Next we have the AIDA64 results, nothing out of the ordinary here to talk about so let’s move straight on to the gaming benchmarks. The last test is just a formality at this point and sees the comparison against the Xonar DX, in terms of performance anomalies there are none and in fact the graph paints a picture of a more stable frame rate compared to the ALC1200 with less extreme low points. When talking about audio quality there could not be more of a difference the Xonar simply blows the ALC1200 away in every imaginable metric, depth is better, the audio has clarity, there is a hefty punch. It has life and soul. Just above the DRAM slots is the first (of six) 4-pin fan headers. The CPU_FAN1 header here automatically detects PWM/DC fans and outputs up to 2A/24W. The PUMP_FAN1 defaults to PWM mode and outputs up to 2A/24W, which is more than adequate for most pumps. Last, SYS_FAN1-4 defaults to DC mode and supports up to 1A/12W. All headers support both modes, with adjustments made in the BIOS. There are plenty of headers and enough output to run your cooling system.

The worst issue though was with memory I used several different kits on the board all using different ICs including Samsung B-Die, Micron E-Die, Hynix DJR, and Hynix MFR. The B-Die kit seemed ok but all of the Hynix and Micron kits had varying degrees of success the Micron kit particularly did not want to work on the Tomahawk one set of DIMM banks the board outright refused to POST and the other set of DIMM banks the most I could coax out of the kit was 2933MHz and that was the kit of Crucial Ballistix I reviewed so know full well the kit is capable of at least 3333MHz. The kit I ended up using for this review is the Klevv BoltX[/u] which as it turns out is on the Tomahawks QVL list for 3000 and 5000 series CPUs while very similar kits from Klevv are on the memory QVL for the 2000 series CPUs. Even with this kit however the Tomahawk still would not POST at some frequencies without the XMP profile being enabled which is quite unusual, the board really doesn’t have a clue on how to set memory timings when left to its own devices. Don’t be fooled by the memory QVL list for the 2000 series CPUs for the Tomahawk at a glance it looks impressive but on slightly closer inspection you will notice the vast, vast, VAST majority are Samsung B-Die kits, not Hynix or Micron. Other manufacturers like Asus and Gigabyte are doing far better on their QVLs for 2000 series CPUs when it comes to actual tested IC variety which is far more important than number of tested brands all using the same ICs. Moving on to talk about the VRM configuration, the X570 Tomahawk uses the ISL69247 controller of which six signals are taken for the vcore portion of the VRM and then doubled using ISL6617 phase doublers. Those 12 phases then connect to the stars of the show, a dozen ISL99360 60A power stages. In the previous Gaming Edge WiFi, MSI used an Infineon IR35201 controller with four signals for the vcore VRM, each doubled using an IR3598 phase doubler.Realtek Ethernet (if theres one thing about Realtek thats stand out good its that driver support for their hardware lasts practically forever)
