I would love to know more about this board as I really like the feature set. Especially the number of sata ports, but scared of vrm temps. Would love to see at least one review of it. The only one I found is some YouTube person that recieved a free one that couldn't even oc it properly. He just used the auto oc dial...... crazy world we live in...

Got to testing the X299 Xpower Gaming AC today. On open test bench without airflow I could output 300W before throttling at 102*C. VRM is IR35201 + 6xIR3599 + 12xIR3555 running at 500 KHz by default.

If the thermal limit of the vrm was 115c vs 105c like the Apex it might actually rival the Apex... not a bad first showing... it even beat the Aorus gaming 9 with a 117c limit....

How much does the switching frequency really matter? It seems to differ a fair bit, but I've never understood how low is too low.

What does it affect? Vdroop?

It adjust the phases to reduce Voltage ripple, not Vcore. The manufactures have it set to optimum at higher loads.

Higher switching frequency allows smaller passive components (caps and inductors) generally speaking. It should improve transient response and may reduce ripple depending on the specific regulators used. It also affects efficiency but that depends on the exact regulators used as well. It can also increase radiated emissions but that depends on other factors as well.

How does it improve transient response?

Found this browsing around for VRM pics

Do you know guys if this is true?

It could be compatible if MSI (like Asus, etc ...) have kept the same fixings (screws in the same places)
Just the thickness of the pad to change maybe
I will test with the R6E and the block of the R5E10
