Hello,
I want to build a small server (backup, nextcloud, maybe minisatip, tvheadend , ...) especially with low power idle consumption and are interested in the Rock64 board, as it has some nice features like up to 4GB Ram or power toggle for the usb ports.
Do you have experience which minimal power consumption can be achieved with "headless" usage and only GBit Ethernet connected?
tkaiser posted at the armbian forum some results with 1.3W (Gbit Ethernet) and 1.18W (fast Ethernet) (https://forum.armbian.com/topic/5098-min...ata-cable/).
And the videos, linked in this thread (https://forum.pine64.org/showthread.php?...9#pid29809), show some similar numbers (but i don`t know if Ethernet was connected there)
That numbers seem to be already comparable to SBC with Allwinner H3/H5. But with the Allwinner Boards you can get even lower consumption with disabling GPU & HDMI Port and lower DRam clock speeds.
Have their already been done some similar investigations for the Rock64 ? If not and I decide to buy a Rock64, I could maybe do such tests.
I have not much experience with Linux yet, but with buying a SBC at first I want to learn more about Linux and maybe also do some development as I have already experience with C, C++ , Java, Python,... programming. Second step would be setting up a "productive" server, which can then be further improved.
I have read that at least at the beginning of the Rock64 development the DRam initialization was done with some rockchip binaries, so maybe no changes to the clockspeed could be made. Has this situation changed?
Also I have read about DRAM DVFS & GPU DVFS and seen some rockchip kernel commits that may be related to that.
Is DVFS for DRam and GPU already working, or are this features that may be implemented/working in the future?
And are their experiences with shipping times to Germany with the standard shipping (11$, not the expensive 30$ express shipping)? Especially with the not so far away Chinese new year ?
If shipping would take to long it may be worth to wait for the RockPro64, which might have mainline kernel support from the beginning.
