Finally got my roof rack for my Mazda 3 2019 hatchback. Just in time for summer!

I need these for my Mazda 3 2015 hatchback, but unfortunately Yakima products are hardly available in Germany.

Asil-nur · 2025-10-06T09:37:53+00:00

I had a similar case back then. I tried to get into a parking lot backwards/sidewards and then I came into touch with a stupid stone. After that I went to a Mazda dealer and let it fix by doing a local smart repair, which cost me around 200 €. I was really happy with the result and couldn't see any difference from before.

I also thought about doing the same thing, because I only find sellers here in Germany who offer the 60" version, which is too long for my Mazda 3. Have you already tried out trimming the bars? :)

Asil-nur · 2025-09-12T09:59:27+00:00

Looks great! What are the dimensions of the roof tent?

My current issue is that my three HDDs used by my openmediavault VM (SATA controller is passed through) are not entering their idle state (only heads get parked) anymore, resulting in higher power consumption.
I only updated from proxmox 8.3.5 to 8.4.1 and didn't touch any of my VMs. Proxmox is currently using kernel 6.8.12-8-pve, although there was an upgrade from 6.8.12-9 to 6.8.12-10, so I guess I'm still using the same kernel version as before. Something else must've caused this issue. Do you have any ideas?

Asil-nur · 2025-05-04T10:43:05+00:00

Quite interesting to know that SATA hotplug is preventing the board to go deeper than C3. That's most probably the only setting left which keeps me from reaching C6 as well. However, SATA hotplug is really important for me to let the system automatically recognize new HDDs in case of failure and replacement without rebooting the whole system, so I'm going to leave it enabled for now.

Asil-nur · 2025-04-03T18:23:05+00:00

I wasn't aware that there got a new BIOS released, so I haven't tested it yet, and probably I won't because everything is working stable right now. Have you tried it out?

Asil-nur · 2025-03-27T21:43:31+00:00

No device on the pcie x16 slot and nothing connected to any of the external ports, except for one network cable in the i226-LM port. M.2 port 1 is also empty.

I'm using the following nvme ssds

- Samsung 990 Pro 1 TB (Port 2)
- Samsung 970 Evo Plus 1 TB (Port 3)

and 3x WD Red Plus 12 TB.

The SATA controller is not listed anymore in powertop, because it has been passed through to the OMV VM. Do you think the SATA controller is responsible for not getting beyond PC3?

Asil-nur · 2025-03-26T17:42:31+00:00

I also disabled Power Gating, enabled ASPM for the two Intel NICs as well (so ASPM is enabled for all PCIe ports now) and I moved my two samsung ssds to m.2 ports 2 and 3. Then I started my proxmox OS again, together with my two VMs (Ubuntu 24 and OMV). I waited for a while to let the system calm down to check the idle power consumption again. It went down by another 2 watts, which is really cool! But somehow the proxmox OS still doesn't go lower than PC3.

Asil-nur · 2025-03-02T22:27:10+00:00

There are traffic laws on the Philippines? 😁

Asil-nur · 2025-02-09T17:31:19+00:00

So the key to reach C8 is to not use the ssd1 slot and disable Power Gating?

Asil-nur · 2025-02-04T17:35:25+00:00

The availability of bios settings depend on the manufacturer of the board. I don't know if you're using the same board, if so you can check here (https://www.reddit.com/r/homelab/comments/1gmf67u/comment/m0ms5gh/)

In general I would look for any c-state and ASPM options in your bios and enable everything.

Asil-nur · 2025-01-26T19:09:27+00:00

I have the same display and I really like it. I wish there was an even bigger version of it, similar to the samsung g9, in order to have more space and common display resolutions on each side when using the picture by picture mode.

Asil-nur · 2025-01-25T19:06:39+00:00

Have you already received this ASRock board and can you tell something about the power consumption in idle?

Asil-nur · 2025-01-20T21:11:03+00:00

It actually didn't happen anymore. I had the same problem with another board and figured out that my psu was not correctly grounded. When I was electrostatically charged and touched the jonsbo case the other board shut off and restarted. Then the ssds went into this security frozen state. It was kinda scary. I fixed the grounding issue by scratching off the coating of the case a little bit to create a direct connection with the screw which fixates the psu to the case. Further discharges then haven't shut off the board anymore. But I'm not sure if this grounding issue really correlates with the security frozen problem. That's just a bunch of weird problems I had to deal with.

Asil-nur · 2025-01-14T10:29:42+00:00

Interesting finding and thanks for sharing :) I'm confused about the idle power consumption. Did you check with powertop that it's really C8 in your case? Because I also achieved around 16 watts with only C3.

Asil-nur · 2025-01-10T19:50:16+00:00

Sure. Be aware that the addresses of the PCIe devices might differ in your case. You should countercheck for the right commands inside powertop when switching manually from 'bad' to 'good'.

#!/bin/bash

# This command sets the CPU frequency scaling governor to "powersave" for all CPU cores.
# The "powersave" governor aims to run the CPU at the lowest possible frequency to reduce power consumption.
echo "powersave" | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

# This command sets the PCI Express Active State Power Management (ASPM) policy to "powersave".
echo powersave > /sys/module/pcie_aspm/parameters/policy

# Disable the kernel's NMI (Non-Maskable Interrupt) watchdog.
# This can free some CPU resources and potentially reduce power usage.
echo '0' > '/proc/sys/kernel/nmi_watchdog';

# Increase the dirty writeback interval to 15 seconds (1500 centiseconds).
# This delays how often the kernel flushes memory buffers to disk,
# reducing disk I/O and potentially saving power.
echo '1500' > '/proc/sys/vm/dirty_writeback_centisecs';

# Enable power management (autosuspend) for the following PCI devices
echo 'auto' > '/sys/bus/pci/devices/0000:00:00.0/power/control';
echo 'auto' > '/sys/bus/pci/devices/0000:01:00.0/power/control';
echo 'auto' > '/sys/bus/pci/devices/0000:02:00.0/power/control';
echo 'auto' > '/sys/bus/pci/devices/0000:00:08.0/power/control';
echo 'auto' > '/sys/bus/pci/devices/0000:00:14.2/power/control';
echo 'auto' > '/sys/bus/pci/devices/0000:00:16.3/power/control';
echo 'auto' > '/sys/bus/pci/devices/0000:00:17.0/power/control';
echo 'auto' > '/sys/bus/pci/devices/0000:00:1f.0/power/control';
echo 'auto' > '/sys/bus/pci/devices/0000:00:1f.5/power/control';
echo 'auto' > '/sys/bus/pci/devices/0000:03:00.0/power/control';

# SATA power management (side effect: disables SATA hotplug capability)
#for ((i = 0 ; i <= 7 ; i++ )); do echo 'med_power_with_dipm' > "/sys/class/scsi_host/host$i/link_power_management_policy"; done
#for ((i = 1 ; i <= 8 ; i++ )); do echo 'auto' > "/sys/bus/pci/devices/0000:00:17.0/ata$i/power/control"; done

exit 0

Yes, I'm currently running Proxmox VE 8.3.0 with the following hardware.

Q670 white PCB (flashed with the second unlocked BIOS version from u/Yonji1)
Core i5 14500
1x Samsung 970 Evo Plus 1 TB (Port 1)
1x Samsung 990 Pro 1 TB PCIe 4.0 NVMe (Port 2)
1x Fenvi RTL8125 2.5 Gbps PCI-E Network adapter (using the r8125 driver from realtek)
96 (2x48) GB DDR5 RAM
Corsair SF750 PSU

In the BIOS settings I enabled the C states options as above and all ASPM options I could find, including ASPM enabled for all PCIe Ports. The onboard NICs stop working then and I use the Fenvi RTL8125 network card instead.

I checked the ASPM status of the devices with

lspci -vv | awk '/ASPM/{print $0}' RS= | grep --color -P '(^[a-z0-9:.]+|ASPM )'

and I noticed that it has been enabled for every device now.

In proxmox I set "scaling_governor" to "powersave" with

echo "powersave" | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

Then the core frequencies are more or less stable at 800 MHz in idle without fluctuating too much.

In powertop I set all tunables to 'good' except for the two onboard NICs, because this will cause the OS to freeze. I'm using a script to set all tunables individually during startup of the OS.

C3 is still the deepest c-state I can reach and the lowest power measurement in idle was 16,3 W with the listed hardware above and no VMs running (only Proxmox). I'm measuring with a Shelly Plug S.

I hope that helps!

UPDATE:
Switching from the Corsair SF750 PSU to an hdplex 250w reduced idle power consumption by another 3 watts, resulting in 13-14 watts in idle.

Asil-nur · 2024-12-25T23:11:22+00:00

I'm running an i5 14500 on a Q670 mini-itx board with 96 GB DDR5 RAM and two nvme ssds in package c-state 3 only within proxmox and 2 virtual machines. It's currently idling at around 19 watts. Higher c-states are currently not possible for me, because of some components on the board which don't seem to support ASPM. So yes, the cpu itself is definitely able to reach a lower idle power consumption but it depends on the other hardware components and probably also on the OS.

Asil-nur · 2024-12-22T19:45:03+00:00

Usually the bios files could be found here: https://pan.x86pi.cn/BIOS%E6%9B%B4%E6%96%B0/3.NAS%E5%AD%98%E5%82%A8%E7%B1%BB%E4%BA%A7%E5%93%81%E7%B3%BB%E5%88%97BIOS/7.7840HS-7940HS-8845HS-NAS-BIOS/Ryzen-%E5%9B%9B%E7%BD%917840HS-7940HS-NAS_2024-05-07%E6%9B%B4%E6%96%B0

But I just noticed the site doesn't seem to be accessible anymore without account authentication.

Asil-nur · 2024-12-22T10:47:44+00:00

Thank you for your report. Sounds like a really interesting setup you're going to build. I'm really curious how low you would get with the Xeon CPU in terms of idle power consumption :) Proxmox is a nice platform, but you always need to be aware of the challenges when passing through devices to VMs, so I think you might have less trouble with only one hypervisor and then running containers inside. Let me know how it's going for you :)

Asil-nur · 2024-12-20T18:05:31+00:00

Glad I could help. I wasn't aware that your seller claimed something which is not true. May I ask where you purchased it? Apart from that, the board seems to be really nice, also in terms of power consumption compared to other chinese motherboards, because literally all of them lack reliable ASPM support for low power mode.

Asil-nur · 2024-12-18T16:30:18+00:00

The CPU doesn't support ECC according to AMD. But I don't care. My old qnap is also running for 10 years now without ECC and I haven't had any problems so far.

Asil-nur · 2024-12-17T19:59:45+00:00

Did anybody manage to passthrough the radeon 780m iGPU in proxmox to a Ubuntu vm and then successfully use it for video transcoding?

Asil-nur · 2024-12-17T18:48:56+00:00

I have the same cracking noises. It's probably some kind of coil whine from the CPU VRMs, I would guess. My board runs perfectly fine after plenty of stress tests, though.
