Hello Forum, i got some strange temperature reported on cores of AMD EPYC 7313P Iam wondering if somebody else got this problem too? The temperature of the CCDs should be valid and i got same temperatures over IPMI. FreeBSD 13.2-RELEASE releng/13.2-n254617-525ecfdad597 GENERIC amd64...

Sorry, i forgot to save the benchmark results, but i think PM1725B results were lower than yours. According to the official specs your results are not far from the maximum: https://www.samsung.com/semiconductor/global.semi.static/Brochure_Samsung_PM1725a_NVMe_SSD_1805.pdf

Take a look at the Xeon-D 1500 or D-2100 Boards from Supermicro. There are some options that may meet your needs. https://www.supermicro.com/products/motherboard/Xeon3000/#1667 https://www.supermicro.com/products/motherboard/Xeon3000/#2518

Sorry, yes, it is a BIOS setting. https://www.supermicro.com/manuals/motherboard/C420/MNL-1967.pdf Page 80

Problem solved. The system builder enabled Intel® VMD for Volume Management Device on CPU for the PCIe Slots, which is disabled by default. :rude: Thank you! nvd0: <SAMSUNG MZPLL1T6HAJQ-00005> NVMe namespace nvd0: 1526185MB (3125627568 512 byte sectors) nvd1: <SAMSUNG MZPLL1T6HAJQ-00005>...

We updated the /usr/share/misc/pci_vendors with a newer version, that have a section with PM172Xa / PM172Xb a822 NVMe SSD Controller 172Xa/172Xb 1014 0621 PCIe3 1.6TB NVMe Flash Adapter II x8 1014 0622 PCIe3 3.2TB NVMe Flash Adapter II x8...

Greetings, I just try to get 2x Samsung PM1725b 1.6TB PCIe 8x cards working on a Supermicro X11SRM-VF using FreeBSD 12 Release. nvme_load="YES" nvd_load="YES" is set in /boot/loader.conf nvmecontrol devlist said "No NVMe controllers found." Does anyone have any idea what else to do? #...

It should be a BIOS bug or something. One of Asrocks BIOS updates for that mainboard has "1.Modify Fan behavior." in the description, so i would check the used BIOS version first. http://www.asrock.com/mb/Intel/B150M%20Pro4S/?cat=Download&os=BIOS

The Bulldozer CPU is "special" with its module blocks. No HTT but 2 cores share 2 integer "clusters" and only 1 floating point unit. https://de.wikipedia.org/wiki/AMD_FX#/media/File:AMD_Bulldozer_block_diagram_(8_core_CPU).PNG A 4x thread FPU workload pinned on Core 0,2,4,6 could perform better...

Maybe "kern.sched.topology_spec" is the sysctl variable you searching for. sysctl kern.sched.topology_spec

I guess this is just a error in the manual, because on another page they write "* The M.2 slot shares lanes with PCIe Slot 6 . When Slot 4 PCIe M.2 is populated, Slot 4 runs at x4." and the source of the PCIe lanes is the CPU(PCIe3.0), so it would make no sense limiting it to 2x 2.0. But...

You can use gstat to find out what is happening on your swap partition. As dlegrand said: You need more RAM or you tune ZFS so it will consume only 2GB RAM in order to avoid that swapping. I would prefer more RAM.

The base filesystem is full, so the dd data is on the UFS partition and not on the zpool.

I guess the 17G are on the 20G space where FreeBSD resides. df -h

The MX31-BS0 mainboard M.2 slots supports only 1x PCIe 3.0 lane with max. "10Gb/s" (should be 8GT/s ... possibly they connect it with 2x PCIe 2.0 = 10Gb/s ... it is confusing) or less that 1GB/s per second. The Toshiba XG3 connects with PCIe 3.1 x4 theoretical 3.9 GB/s and its read/write speed...

It is a bit more complex and depends on the workloads, I would say. A system block diagram illustrate that way better. The M.2 Slot on this board is connected with 2x PCIE 3.0 . The X11SSH-LN4F f.e. page 17, Figure 1-4. System Block Diagram...

The manual section of this board is a joke, but at least in the specs they deliver some information: "The MX31-BS0 comes equipped with an onboard M.2 slot, providing users PCI-Express connectivity for SSD devices. Delivering up to 10 Gb/s data transfer speeds..." According to the CPU (XEON...

Interesting, a SIM card slot, but for what kind of modem?
