[@bambinone]

Hi Seb, a few quick notes from my own experiences. RE: motherboard, I would recommend staying away from B450. It's not a very good chipset, it'll struggle with higher RAM speeds, it won't have good resale value, and most B450-based boards I've worked with aren't the greatest quality overall. The main thing you want to look for in a board is a decent VRM with a big ol' heatsink. I had a Gigabyte B450M DS3H paired with a 3900X and it was only getting 11KH/s and it would crash a few times a day even with a fan pointed directly at the VRM heatsink. After a few weeks of trying to fix it I finally gave up and switched to an MSI B550-A Pro-which is not a particularly great board, but it has a good VRM with a solid heatsink. Now that same 3900X is steady at ~14KH/s and never crashes. RE: RAM, I've found with RandomX that memory speed and timings matter the most when you're already pushing the CPU as hard as it can go, i.e. way outside the efficiency sweet spot. Once you've undervolted and tuned PBO (specifically PPT)-or determined the best fixed voltage and frequency-the difference between e.g. a kit of 3733 CL14 and a kit of 2933 CL18 is pretty marginal. I actually have a kit of B-die running at 1V (XMP disabled) with the aforementioned 3900X for optimal power efficiency. That being said, if you plan to do profit-switching with Monero Ocean or what have you, I think it probably makes sense to get a decent dual-channel (and ideally dual-rank) kit that runs at 3200 CL14 or 3600 CL16 or thereabouts. Then you can run 1:1:1 MCLK:FCLK:UCLK and it'll be great for any algorithm now or in the future. And again B550/X570 are more stable at 3600+ MT/s. RE: CPU, I've been seeing the Ryzen 9 7900 (non-X) for about $330 and at that price it's starting to become pretty attractive. The 7900 is essentially a 7900X that comes in ECO mode out of the box, and it includes a stock cooler. So if you can get a cheap AM5 board and 32GB kit of DDR5 it won't cost much more than a new 5900X rig. However AM4 still wins on value once you start considering used gear...

[@SebsFinTechChannel]

Wow lots of amazing info here, thank you so much for sharing this, I can see you really know your stuff! :)

[@bambinone]

@@SebsFinTechChannel I've learned so much from you over the years, it pleases me to be able to share some small tidbits with you. Cheers!

[@sebgeese]

Hi, I have 4 CPU rigs consisting of 3xRyzen 9 3900 with 16GBRam 3200Mhz CL16 installed on a B450 , the fourth RIG is a Ryzen 5 3900 with 2x8GBRam Dual Channel installed on an X570. All four boards reach an average of 10KH with the CPU setting from Rabid Mining. The settings for RAM unfortunately cause crashes for me. Otherwise, I have to say that 3Boards run very stably at 53 degrees Celsius. Only the fourth was always at 63 degrees Celsius and often crashes. I would also be interested in how I can further increase the KH. Oh yes, I mine Monero with NiceHash. Greetings from Germany, Sebastian

Hey Seb. Great video. All the support hoping we survive this brutal bear market. All the best Seb

[@Arek_R.]

randomx is profitable now even on residential electric if you point it at nicehash, my single 5950x rig earns same income as my entire 6x3060 rig... I remember watching SOAT's video on CPU mining rigs and he said that mobos with two 8 pins are beneficial for max hashrate, lol... I run my entire CPU rigs off single 6 pin from a server PSU hehe

[@wnichols99]

Great video. Recently got into CPU mining. Cant wait to see the overclocking videos

[@SebsFinTechChannel]

Me too! Will be fun learning the process for finding optimal overclock settings and then sharing that with you guys :)

[@GusRJ70]

Hi, about RAM, why CL14 instead of CL16? I have some difficulties to find this model in my country. Tks

[@coinology2022]

Awesome video Seb!

[@coreanstacker5427]

I get the following error message when I try to flash HiveOS using balenaEtcher: "Something went wrong. If it is a compressed image, please check that the archive is not corrupted. The writer process ended unexpectedly." I tried balenaEtcher on my USB stick, M.2 drive, and also SSD. The same error regardless after flashing and validation. Any idea why?

What about the 5800x3d? Nice hash calculator puts it at much better profitability than 5900x

[@Nikon285]

Dude, love the look with that GPU you threw on the rig behind you. What model card is that? Can't hurt to add it to your CPU mining build list either for Amazon affiliation. I'd have clicked on it just to see. It's a good look and might try to find it once you share which card it is! Thanks for all the hard work over the last few years, been watching you since RPM promoted you and got you those first 1000 subs if I remember correctly!

[@SebsFinTechChannel]

Oh man, I remember that shout out! I was so proud, felt unreal! I still really look up to RPM. Thanks man I really wanted to find the coolest card I could to make it as awesome looking as possible for you guys since it's gonna be in the back of most of my videos. It's an MSI 3070 SUPRIM X, and if you want to support the channel with a small commission at no extra cost to you (I have to say that line, every time, lol), you can get it through this affiliate link: amzn.to/3PCbvOu but TBH you can probably find it cheaper used on eBay. Or if you wanna get a brand new card from Amazon for mining I'd probably rather look at the MSI SUPRIM X 4070 Ti: amzn.to/4390XK3 or 4090: amzn.to/3Xv1UuZ as they are both better for mining nowadays (although definitely more expensive...).

Is CPU mining worthwhile given the electricity prices? The hardware is not exactly cheap either. How long do you have to work with it until it pays off?

[@MineSum10]

Great stud Seb. I’ve also been diving into CPU mining. Having a hard time deciding on consumer grade vs server grade. The AMD Epyc stuff is very enticing and will perform really well for PoUW when the time comes. So many variables. I think it is time for a spreadsheet. 😉

[@SebsFinTechChannel]

Yeah there's definitely so many possible avenues to go down in mining right now. Exciting times hey! :)

[@rlo_YT]

The 7551 is cheap but the mobo are super expensive unfortunately

[@bambinone]

@@rlo_YT Not enough cache on the 7551. IIRC I think you need about 2.5MB L3$ per core for optimal efficiency. Look for Zen 2 EPYC (i.e. fourth digit is a 2) instead.

[@USrolexinvestors]

Great info thankz

[@MRX625.]

Hi Seb. How are you doing? I got your advice about the CPU choose, but what do you think about the new 7950X3D? It has both power efficiency and almost same price as 7950X. Would you recommend it for CPU mining? :)

[@TheOnlyHurrycane]

I am not sure what motherboards you support the most, but I would recommend the MSI or AORUS motherboards instead of ASUS. I am a CPU miner, and I got a several rigs on CPU. The reason I would adress this is because ASUS motherboard just support RAM-sticks that are listed in their vendorlist. If you use, lets say, a memory stick from an unknown vendor, but have the same "settings" as those on the vendorlist, the ASUS motherboard will not boot-up when you have them in dual-slot or more. But it will boot up if you have it covered in one slot. ASUS are very strickt on this issue, to make sure you use the correct vendorlisted ram for their motherboard!

[@kang7014]

when powering 2 rigs with 1 psu, if the rigs are windows, will they work ok? if one rig restart, will it affect the other rig?

[@user_cmyk]

Can I use this set up to add GPUs on top 2~6 depending on the motherboard to add GPU mining power? will that hinder the ability to mine with the CPUs? or the double CPU setup? Thank you in advance.

[@SebsFinTechChannel]

You can absolutely add GPUs to a setup like this, just make sure the power supply is powerful enough to handle it. Good luck!

[@lemoncryptonfa4980]

Will this rig be great for xen miner (XenBlock) ?

[@peterm5924]

can you suggest a low cost gpu?

[@dubbyx8490]

Yo! SEB.. I'm interested in the 7950x AM5 build.. Also, this need for GPU is it really necessary? If so, can I just use any old GPU?

[@SebsFinTechChannel]

Awesome! Yes you need a GPU but like you say it can be literally any old GPU, you just need something that is able to put out a video signal the first time you set up the rig as these AMD CPUs don't have any built in graphics. But after you set the rig up the first time, you can power it off, take the GPU out and then power the CPU rig up without any GPU in it. But any time you need to see what's going on on the screen for the CPU mining rig, you need to plug in a GPU first. Hope this helps :)

[@dubbyx8490]

@@SebsFinTechChannel Ohh! This makes so much sense.. This GPU bit should definitely be included in your 7950x build video.. Thanks for the help.

[@bambinone]

@@SebsFinTechChannel Some boards won't POST without a GPU. One advantage of AM5 rigs is they have an (admittedly shitty) iGPU.

i started watching rabid's guides a couple weeks ago , no jk i watched like 10+ videos 😂 cuz it felt way complicated than gpu - ASIC mining and eventually entered the cpu mining scene with 3900x 180$ and x570 99$ and 8GBx2 3000 30$ all of them used but the rest which is the storage,case,psu all were sitting doing nothing so i used them

What is the cooler on the CPU and how did you get it? It looks like a model that was discontinued by AMD, but I just wanted to check.

[@SebsFinTechChannel]

It’s the AMD Wraith Prism cooler that comes with the 3900X :)

If processor doesn't have display, can I use any gpu or does it effect CPU performance. Thanks for any clarification. If using windows for mining.

[@SebsFinTechChannel]

it shouldn't affect cpu mining performance, and you can mine on the gpu too

[@diogenes2875]

If the rig pulls 100 watts, can you just buy a 1000W power supply and run 5 of those same type rigs on it? Do they sell 5 port splitters?

[@areutryingitout5678]

They won't have 5 4+4 cpu connectors, and you don't want to split those.

[@rasmuslindberg6212]

hi sebs, is the MSI B450M-A Pro Max a good motherboard for cpu mining?

[@SebsFinTechChannel]

Hey hey. The best deal I've seen for CPU mining motherboards recently is the MSI B450M PRO-VDH MAX, which is similar to the one you've mentioned but has VRM heatsinks which is a big plus for longevity and stability. Honestly it's my new favourite motherboard for CPU mining. If you wanna get one and don't mind supporting the channel with a small commission, here's an affiliate link to it on amazon: amzn.to/3T0BjW0. Thank you! Hope this was helpful.

You said you can get any Ryzen 9 cpu and go for what’s cheaper. The 3900x seems to be going for $360 usd on major retailers while the 5900x is going for $300 usd on major retailers. In your previous video you said the the 3900x is second only to the 7950x. So my question is would someone be leaving a lot of performance on table going with 5900x vs 3900x?

[@Sumit-wo8pq]

No around 600-700 hashes per second

[@Airwaves121]

Hi Seb. How does the 3900 pro processor compare to the 3900X in mining?

[@GreaterGoodMining]

Hey Seb! Long time subscriber and fan. I was on the live stream with you and RPM yesterday and you asked about throughput and getting videos out faster. I had no idea how long it takes to make a good video until I started doing it myself. Have you ever considered hiring someone to edit and put your footage together? That's what takes me the longest! Sometimes I spend 6 to 8 hours shooting and editing

[@SebsFinTechChannel]

Hey man! Yep I'm well aware of your channel I've watched quite a few of your videos. :D By the way I wanted to ask you, you mentioned the rejected shares on Herominers for your KS0 might have been due to using the wrong stratum. Did you try it with a different stratum? Did that fix it? And yeah content creating really does take a lot longer than what people might think... For me it's usually about a full day doing research or testing, then takes about 2-3 hours writing a script, about an hour to film (I use a teleprompter which really makes filming a lot quicker), then editing takes about 3 hours and thumbnail design varies between about 2-8 hours depending on how complicated my thumbnail idea is. Then add to that all the invisible work of running a youtube channel like coming up with video ideas, doing all the bookkeeping, emails back and forth with companies, being active in the community and social media, constantly improving your skills in terms of filming/editing/youtube SEO/design, the list goes on LOL. I'd say I work about 12 hours a day 6 days per week. I wouldn't trade it for the world though, best job I've ever had, even though I make less money than ever haha, but it's worth it. As for having someone doing the editing for me, that would be a great time save but looking into it prices seem to be around $200 per video which I can't afford.

Hey Seb. I am trying to figure out how to mine with my cpus and get paid out in Xrp with unmineable but I just cant figure it out, I have tried for quite some time now.

Would be much appreciated.

[@SebsFinTechChannel]

Make sure you set up your HiveOS flight sheet to mine the coin of the algorithm you chose, not the coin you want to be paid out in. I know that's a common mistake people make when using unMineable in HiveOS. You can see how to set up HiveOS with unMineable at the end of this video: kzbin.info/www/bejne/n2SqYmiDpLCpetU The setup there is for GPUs but the process is the same.

[@mancavetech]

Did I skip the cpu cooler part? Stock AMD Prizm ones work very well. Also Mini-ITX mobos will save a lot of space and not that much more. 45 degree plastic stands are also awesome to save space.

[@SebsFinTechChannel]

Yes I totally missed that in the video. Stock AMD Prizm cooler is totally fine.

[@bambinone]

Once you get power consumption optimized (either by tuning PBO or with a fixed voltage and clock ratio) you have a lot of flexibility on the cooler. You should be running at about 65W core, so the Wraith Prism or even a $20 single-tower cooler is sufficient.
