September 24, 20196 yr Hi. I am new in the Unraid area. I built my 1 st server and I need help please. My hardware is: M/B: ASRock Z390 Phantom Gaming 4S Version BIOS: American Megatrends Inc. Version P1.20. Dated: 05/06/2019 CPU: Intel® Core™ i7-9700 CPU @ 3.00GHz HVM: Enabled IOMMU: Enabled Cache: 512 KiB, 2048 KiB, 12288 KiB Memory: 32 GiB DDR4 SATA controller: DELL perc h310 (flashed) for AHCI mode Harddisks: Parity (1x12TB HDD), Array (2x12 TB, 1x 8TB), Cache: 1x M2 Samsung SSD 500 GB my problem is: I can only do 1 task simultaneously. i.e. if I copy in the background 1 file, 8 CPU threads run up to red 100% and the stream, which is running at the same time, is freezing, until copying is finished. It doesn't matter what I do. unpacking, copy, moving or downloading files, always the same. As soon, as I try to start 2 things parallel, 2nd task starts to freeze or even go very slow until the other task finished. I followed the instruction to setup the BIOS from here: BIOS Settings The only thing I didn't find was: Hyper-Threading, the rest I changed as it is described in the video. I tried the HDD's on both SATA controller (Dell perc and onboard). Same result, unfortunately. My hardware should be powerful enough ti handle this, right ? What else can I check? - Does someone know this problem? Thanks in advance for help. Installed plugin: Fix common problems: 0 errors found. Edited September 25, 20196 yr by joghurt [SOLVED]
September 25, 20196 yr Author Thx for reply. Indeed, this seems to be my problem, too. I downgraded to 6.6.7 and the freezing problem disappeared.
