As mentioned on the introduction, I was not able to get the PSU upgrade I was hoping before I decided to make this review public. If we are able to get an upgrade, we will make an article stressing the 2990WX overclocked. Nonetheless, we were able to test the AMD Ryzen Threadripper 1950X to 1.425volts on the VRM Tests.
Remember, for Ryzen 1st gen, it is “okay” to use up to 1.425v, if you are manually overclocking. On Ryzen, second generation (Zen+), the maximum suggested is 1.38v. Depending on the cooling solution you have, you probably will get a thermal bottleneck depending which CPU you are using. (In CPUstress tests).
We were able to stress the X399 Designare EX before the X399 AORUS Xtreme.
Remember these temperatures are Delta over ambient.
We are glad to see that the new motherboard packs better temperatures in comparison of the X399 Designare EX. We did like the Designare EX in terms of performance/looks using the 1950X. (we did not review it, but we used it for months and did some inside tests). The only issue that motherboard has is that the VRM was not beefy enough for the 1950X overclocked using 1.425v.
On heavy workloads, the stress on the VRM was high on the Designare EX. The X399 AORUS Xtreme has no issues to keep up temperatures in control.
On a side note, as mentioned before, the motherboards has two fans cooling the VRM that ramps up RPM when the VRM starts getting hot. On BIOS, you can do manual tweaking to the curve or have it at full throttle (if you like).
Now if you are wondering what are the temperatures using a 2990WX on stock settings; it is lower than a 1950X overclocked at 1.425v using OCCT.
For technical data that might be useful for you, the VRM throttle temperature for the X399 Designare EX is 103 degrees Celsius according to HWInfo Sensor (it has an Over Temperature Protection). We did not reach the VRM throttle temperature on the X399 AORUS Xtreme, but according to internal documents, it should be 115 degrees Celsius.
It is not surprising the Ryzen Threadripper 2990WX consumption is high, even on idle. Here is the full table for the X399 AORUS Xtreme, measured by Total PC Consumption from the wall. As a reminder, The Witcher 3 during this test was on stock settings, meaning the full 32 Core setup.
Obviously, this was unplayable even on 4K due to stuttering. Remember to change to Legacy Mode or Gaming mode if you ever use the 2990WX as a gaming PC on your spare time.
