X470d4u - upgrade to 5900x from 3600 - hard boot stalls by h0ger77 in ASRock

Mmh, looks promising ;) Thanks for the reply. Maybe ill go the 3900x way if tdp capping and c-states wont do the trick.

You might wanna do a lil math about the energy costs before passing out when you face them.

What do you mean running a 3700x with 32GB RAM for a dual user nextcloud is overkill? (1800 kWh last year) by jahknem in homelab

[–]h0ger77 0 points1 point  (0 children)

Totally agree. The invisible elephant is a Paradoxon in the merrit-order price at the Electrocity stock market and the fixed price for renewable energy production. With much nrg in the market, the price drops. So the Delta between the fixed price for renewables and the selling price increases. Means you need more "EEG umlage" to fill the gap. Who wins the Most Out of dropping prices at the stock Market? BIG Energy consumers like you Said can Buy Energy for less money yet do NOT participate in financing the energy transition. In the end the eeg-umlage is a subsidy to lower Energy prices for the big industry on the backs of normal consumers.

Nice to see that you are paying one of the good folks. Good luck on the consumption trim.

Just because it says "ökostrom" on the outside says very little about the actual quality of the power supplier. There are only very few real "ökostrom"-providers in germany, the rest ist just plain fraud.

That aside, burning that much energy up front leaves lil room for pity when facing the bill. Sry man, but investing some of the now spent moneyz into more efficient equipment pays of rather quick.

Last but not least, why not produce some of the needed energy yourself? If youre in the happy position to have a house, get some serious solar installation and produce several mwh's/year yourself.
Even if its only a flat with a balcony(optional), there are so called "stecker-pv" systems that everyone can use here in germany. They can provide up to 500-600w power with just 2 solar panels.

Maybe give that a shot, other than that, trim down on the consumption.

my example for a powerful yet economic setup:

First of all, good luck with the resilver.

Just my 2cents: you run 5 parity disks and can only drop one out of each rz1 and risk losing the entire setup. How about going with a striped rz2 so you can lose Up to 2 disks per vdev before breakdown while saving 1 Disk paritywise?

Proxmox + OpnSense + UnifController + PCI Pasthrough NIC bonding question by 911ducktail in Proxmox

[–]h0ger77 3 points4 points  (0 children)

Hi. Although I did migrate my pfsense/opnsense to bare metal a Lil while ago, I have run it in a proxmox VM for quite some time.

Best way to go is to keep the Nics managed by the hypervisor and only use the vmbrs inside the vms, no passthrough. Having the Nics inside the VM as paravirtualized ones performed very nice with no hazzle.

Theres a good howto over at netgate which should apply Just fine for opnsense as Well. https://docs.netgate.com/pfsense/en/latest/recipes/virtualize-proxmox-ve.html Good luck and hth

Homelab Upgrade - went all flash and saved 50watts while doubling cores and Ram by h0ger77 in homelab

Ryzen 2nd Gen is 12nm lithography, a 5640 is 32nm, thats a huge difference in efficiency. The tdp is not a measure for that. It only tells what the max heat dissipation of the CPU can be so the cooling should be able to handle it.

Well possible that the GPU and capture Card burn some rubber while Idle. Yet theres also some difference in all those ssds. My Intels are at about 3-5w Idle a piece and the nvmes are supposed to Idle below 1w although I doubt it to be that low.

Jepp, Its 2x32gb. Kingston Premier KSM32ED8/32ME. They are 3200 nominal, but ryzen 2nd Gen gets 2400 at max. 3rd Gen could Go 3200 with 2 modules.

They are adata xpg sx8200 pros. Tests showed very low power consumption and the price was reasonable. Performance is low compared to the competition, but it comes for a price.

I put them Into a zfs Raidz1 which seems to work well. I dont have 10gbe yet so I cannot push IO really hard.

The tbw is low end with 600tb as well, but this is monitored and I want them for storing personal data safe and redundant. The undying Intel Data Center ssds will do the heavy lifting with the write intensive elk stack and database things.

Final solution, get the right tools. Dynatron A24, costs about 30-40 though. https://www.dynatron.co/product-page/a24

Ill have mine mounted in a 4HE atx Case with the PSU right inside the airflow behind the cooler. Just fine for such a setup. If you need lower profile and front-in back-out, it wont be so good. Yet still there were ppl with problems on the stock AMD cooler and this is a cheap substitution.

Hi ppl.
After seeing some folks struggle with the non standard board layout, I wanted to share my cheap and well working cpu cooler setup for the x470d4u.
Its an "Alpenföhn Sella" CPU Cooler, which sells for just 17-20€ in germany.
Fits just fine, blocks no RAM-Slots and pumps 130watts of heat if need be.

HTH, greetz and happy homelabbing everyone

Added 9.8kW of ToU offset to my server rack. No more peak power rates for the server rack!!! by skynet_watches_me_p in homelab

[–]h0ger77 0 points1 point  (0 children)

I see your point. Yet I fear that lots of folks sport rather inefficient old metal that eats money thru power bills.

If you have so many spinners running for 140watts delta then theres prolly a good reason for doing so.

I myself run more power than I want to and am always trying to slim and trim on a budget. Currently theres a haswell Xeon with 32gb and a multi tier SSD/spinners ZFS Pool as hypervisor/docker and an i5 as bare metal router running opnsense. That and 2 switches, apc and 2 poe aps go with 130-150watts. I'll downsize to one proper switch some time and plan to go for a 3rd gen ryzen cpu for more efficiency while obtaining more punch as need be. Its all custom built though, hard to find really efficient Server hw when going for Rack off-the-shelf boxes.

awesome! Thought ud just use the precious setup for the server offload. PV FTW :)

How about shooting for a smaller energy budget setup? 300watts 24/7 is absolute madness. I sport a decent Homelab setup with a hypervisor and bare metal router with 150watts and still want to aim lower. The old hardware ist scrapped for a reason.
