Love watching you geek out on this stuff.. another helpful video..

[@DigitalSpaceport]

The A4000 is such a killer card. Really great for that next step past 1PB. Glad to see such an affordable SM V5 setup hitting just 25w! Awesome video

[@HomeSysAdmin]

I'm glad I moved this direction rather than the 3060 I was looking at originally for farming. SO much better, just had to wait for the right deal :D

@@HomeSysAdmin Would A2000 12GB do any good?

[@slowesttimelord]

Absolutely love this hardware content, great stuff!

[@shephusted2714]

going bare metal has its advantages evidently

[@AnwarMangla]

Excellent. I built one with 5019S-WR and it worked great

[@JasonsLabVideos]

Good video sir !

[@markottaway6899]

Love your content, who doesn't get excited by the light show. Have you thought about keeping the farmer on a VM and the harvester on physical hardware, this keeps chia in sync while the harvester is down and reduces outage window on reboots etc

[@HomeSysAdmin]

Thanks! That's similiar to how I was doing it prior to gigahorse. I had the Chia node running in a VM then a harvester running on the bare metel host. I guess I could split it out the same here, but not sure it's worth the trouble for me personally. While working through this video, I had gigahorse shut down for more than a day and it only took 20mins to sync back up. It's nothing like the early days thankfully where it took HOURS.

[@juliusgu]

Great stuff as always, love to see how chia farms evolve over time!

Sweet video

[@weniweedeewiki.6237]

This is a brilliant channel keep up the good work i will be watching waiting for your next video....peace

[@georgeries]

Amazing video, thank you!

[@thenanook]

your videos are PRO, just try to make a little studio, but content… perfect , very easy to understand. thank you😊

[@OffGridAussiePrepper]

Love these hardware type vids but have 1 complaint or maybe 2..... 1stly i am jealous u get this hardware cheap and its accessible to u where u live, 2nd..... I watch utube on a 55inch tv screen and i still cannot read the text u r showing us, not sure how ur gonna fix that but would like to see it for future reference..... thumbs up as per usual.

[@HomeSysAdmin]

Sorry, I've heard it's difficult to find reasonably-priced hardware there. HBPowerwall (I think you know him) was trying to build out a Chia setup a while back and he had a heck of a time finding drives that weren't insanely expensive. I'm not sure on the text though. I purposely enlarge it when I'm doing screen captures. Please make sure you're using at least 720p on playback, anything less like 240, 360, or 480 will probably look like poo. And thanks! :)

[@OffGridAussiePrepper]

@@HomeSysAdmin Unfortunately i have a data cap at full speed aka 15mb down on average till i hit 75 gb and then 1.5mb down till the month ends, so i had to download at 360p to get max utube vids in the calendar month. I will try to re download ur vid at 720p and see if theres mush difference but it will be a slowwwwwwww download lol as streaming will not work for me on such a shi|t connection speed, if starlink was an option which its 200$ promo price for hardware right now and $140 a month but its the $140 a month which kills me to be able to afford it, the one off cost for hardware is doable... so i am stck with this celldata access as nothing else works where i live. Yes i know Pete... I take the p|ss out of him as much as I can and one day I will have a beer with him as he is lives 1000miles away from me. BTW count ya self lucky to have a hobby that u can have ur needs fullfilled to the US economy tanks and u decend into a recession and the US dollar is not the trading currency anymore.

[@OffGridAussiePrepper]

@@HomeSysAdmin The difference is night and day from 360p to 720p...... but I will never know when i need the extra resolution b4 i watch the vid :(

[@mctscott123]

Would one of those supermicros be fast enough to route 10G fiber through OPNsense?

[@webby459]

I think I see that server has an nvme slot too? That is a nice option for ppl as well. Question, will you use this for plotting too?

[@HomeSysAdmin]

Yes! It does have an nvme slot and I'd probably be using that if I didn't already have spare SATA SSDs lying around. A nice 1TB would be perfect for the OS + blockchain. I will not be using this for plotting. It only supports up up to 64GB of memory and need quite a bit more for k33 ram plotting.

[@ronwatkins5775]

I heard you need 256GB for GPU rig, how are you able to run less than that on your system?

[@HomeSysAdmin]

I'm only farming with this - no plotting. My plotting machine has 768GB memory.

[@ronwatkins5775]

@@HomeSysAdmin Is RAM requirement different for farming and plotting? Thought it was the same. I have several 1U HP DL360's and wondering if I can squeeze an A4000 in there.

[@HomeSysAdmin]

​@@ronwatkins5775 Yes - very different. Gigahorse doesn't specify system ram requirement for GPU farming but you would probably do fine with 16GB. Last-gen server ram is so cheap though might as well pile a few sticks in...

[@Gottlib]

Could you share A4000 and CPU working temperature?

[@HomeSysAdmin]

GPU is running at 78C currently with an estimated half load. It gets way too hot at full load honestly, needs better air circulation. I've seen it hit 90C with a 100% load. I'll be addressing this soon - I need a new case anyway due to purchasing a second card. The CPU sits around 30C while farming - it's very efficient there.

[@Gottlib]

@@HomeSysAdmin thanks for answering. What CPU is? I have EPYC Milan 7003p and it gets really hot, at least in impi. Do all your fans work at maximum RPM?

[@startrek716]

But i have alot of looking up quantity alerts and they are less than 30 seconds under A4000. is it serious ? I have 2-3P plots

[@HomeSysAdmin]

Are these Gigahorse plots? Which compression level? I'm running 1.5PB of C8 and the load is very low. Is it possible there's a disk IO issue - ie a bad/failing drive or bad cable somewhere?

[@Gottlib]

Could it fit any 2 slot GPU?

[@HomeSysAdmin]

It will fit a 2-slot GPU yes, but I highly doubt it will get enough airflow because the fan would pretty much be resting against the bottom of the case.

[@Gottlib]

@@HomeSysAdmin Thanks!
