janstefan, I just ran CINEBENCH R15.038_RC184115, CPU and received a 5132. Here is my specifications:
MSI X399 Creation, Threadripper 2990WX, 3xSamsung SSD 970 EVO RAID0, 4xSSD 960 EVO on
MSI AeroXpander RAID10, 1TB & 500 GB WD Black, G.SKILL Flare X F4-3200C14Q-32GFX,
Windows 10 x64 Pro, EnerMax-MaxTytan-EDT1250EWT, Enermx Liqtech TR4 280 CPU Cooler,
Radeon RX580, UEFI E7B92AMS.127, AGESA SummitPI-SP3r2-18.104.22.168
Here is my Ryzen Master:
I am running my memory at 2400 MHz and have no RAIDs right now. Please post a screenshot of Ryzen Master (RM). Please make sure it is the latest version, 1.5.0.0850. Enjoy, John.
EDIT: Threadripper has quad channel memory support. With only two sticks of memory, your memory speed will be half what it can support. I recommend you get a 4 channel memory kit.
