It's not like you'd be buying just the cpu/apu for mining, it's that it would be a nice bonus.
In the same way that my R5 1600 is making an extra buck a day on my desktop, maybe you'd get $2 or $3/day on top of the GPUs.

What are you guys mining on your CPU's? I have two R7-1700's and a R5-1600 just sitting idle at the moment. VEGA's are paying off pretty quickly mining XMR and getting closer to paying off my first VEGA 56. Rest of my cards are still mining Ether.


The Asus B250 is up to 9 cards now (a mixed lot) and I'll be adding a few stragglers to bring it up to 11. I like this board so far even though cable management is near impossible.


Here's a few pics of the mess so far since you guys seem to like my ghetto rigs.

I don't mine with my CPUs. Too energy-inefficient.
I don't think that's true with Ryzen 5 1600. If an RX 570 takes 120W, and a Ryzen 5 1600 takes 65, and the Ryzen 5 1600 makes $0.89/day, and the GPU makes $1.50-1.69/day, it seems pretty-well matched, as far as $ per TDP.

There was a brief period a week or two back where Nicehash was mining very, very well on my 6700k (everyone's profits upticked a bit for a day or so), but other than random fluctuations like that it's generally not advisable to CPU mine unless your power is free or very cheap. I think last time I calced it out, I would make about $20 a year with $0.08/kwh electricity (pretty cheap).

Results may be different for lower power usage/higher core count CPUs.

Wow, you are still running on the first Polaris cards ever released. The stock blower seems to be quiet loud though. I like my cards at under 65C for long term and to be able to sell them later on. The cables are a nightmare.

When did you get your Vega? It seems to have good ROI times if I can get it for $660 + tax(CDN) but I wonder about what happens if Monero, the only coin for it drastically falls in profitability. With Polaris you have few other options.

No. You're still matching 1 GPU to one CPU, which is just not favorable for mining. Something with a tiny ARM core and a barebones motherboard for I/O would be interesting though.

I get ya now. I was thinking just on a pure efficiency base for one card. Yea, no you can't get multiple of them.

Hmmm... most alt coins are getting pumped pretty hard mostly from Korea during lighter than usual trading.

Next week will be exciting!

Heads up that the Ledger Nano S is on sale for the weekend. Shipping is a little steep but given the current ETH price that shouldn't be much of a dis-incentive

I bought my VEGA 64 WC on launch day, and Vega 56's shortly afterwards. I just ordered two Vega 64's last night from NewEgg Canada's eBay store. $749 with free shipping, add on 6 - 7% cashback and they're decently priced given the current landscape. They limit you one per order apparently but I'm fighting to get the second one though as they posted no policy on what the actual limit is.

Not worried about Vega long term. It's a mining beast (2000Mh XMR, 44 - 46Mh Ether) per card. Properly tuned they only consume around 175W mining XMR, best mining card by far but finicky to setup.

Blower fans are the best (IMHO) for mining over long periods of time (all of my blower style 480's still running strong after 16 months 24x7 mining). I don't care about noise that much and keep my blower cards in the 60 to 70C degree range.

A lot people are waiting for aftermarket VEGA's but the 56's will likely be hampered by memory speeds (not flashable to V64 BIOS I'm guessing) plus the reference design is overbuilt given how much energy they consume mining. Reference cards may have worse resale vale but they work really well as miner's and I plan on keeping these cards as long as they remain profitable.

I finally sold off my remaining 28nm cards though.

Vega 64 was down to $499 USD about a month ago, but those prices are gone. Maybe I shoulda gotten one but I was on the fence about it.

I get XMR, but with Ethereum its more profitable using Polaris. Polaris also does well with Equihash algorithms. I like to think having more algorithms as a safety net in case mining profitability drops significantly on some of them. But maybe its different for you because you had Vega cards early.

As for power consumption, as of right now, and likely for few months down the road, Canadian winters will ensure they'll act as electric heaters, and can offset most of its electric costs. Unless you have a huge setup going in your house.

I also thought winter would be a great time for the cards to act as a space heater, but unfortunately I soon realized that the room I set up my mining operation in was right next to our NEST, so now it thinks the temperature of the house is the temperature in the mining room, and either keeps trying to run the AC or won't turn on the heater even when it's cold as shit in the rest of the house. Oops lol.

Heh... sounds like you should spread out your mining rigs so each room has one, like space heaters

This is, sad.

You should be able to set custom heater settings like you can do custom fan settings on GPUs. Maybe AMD can talk to NEST guys about it.

Mining rigs doubling as a space heater was my intention for the winter. I have a couple more computers I could bring online but sadly here in Sothern California, we are still getting 80 sometimes 90+ degree days

I kinda did that. I only have the two dedicated rigs, but they do a nice job of heating up their respective rooms. Had to spread em out to avoid tripping any circuit breakers.

You're lucky. Both of my rooms are on the same circuit.

Mostly. It's probably aluminum wiring in this house (ick) so the usual 20a limit per circuit is not something I'm looking to push too hard. I usually won't go past 1800 watts.

Plus one of the circuits is linked to the garage so if people use too much juice from outside - as happened somewhat recently - it trips the breaker anyway. Joy!

We did tweak it a bit from the normal settings, which helped a bit. I would have preferred to spread them out like ultimatebob mentioned, but our spare bedroom is currently temporarily inhabited. And, I don't like them in my room

i've been having issues with the monitor sometimes not receiving signal after being turned off for a while. i discovered that turning it off and then back on again usually fixed it (the computer wasn't hung, i could still remote into it). i thought it was maybe the displayport on the monitor going bad.

over thanksgiving something happened and the computer crashed. restarted it, started mining, came back a few minutes later to the fans at 100% and the computer not-responsive. cycled the power and nothing came up. no bios screen or anything. swapped to hdmi, still didn't come on. remoted in and it was stuck at 800x600 instead of 4k like usual.

so, out went one hawaii and in went another (thought the second was faulty so it's been laying around a while). still no signal. thought maybe i'd try swapping pci-e slots, but poked around on the internet and saw that some people had no signal due to power issues. swapped from one set of pci-e cables to another, and a different port on the power supply, and walla, signal.

however, now its mining at 12 mh/s instead of ~28. still pulling down ~200 watts from the wall to do so. clocks look right in the amd control panel. obv, i'm not about to spend 200 watts for 12 mh/s.

i've got a new power supply on the way already (seasonic focus plus), any thoughts as to other steps i might take?

I haven't done the calculations since the power registry tweaks but I think aside initial cost, Vega's are more profitable mining Ether than Polaris even accounting for power consumption. I'm in Canada and yeah I heat much of my basement and garage with miners. The basement miners heat the main floor and on the second floor I have a few single card miners to heat the hallway and master bedroom. NewEgg canceled my second Vega 64 order so I'm only at 4 Vega cards but will wait for a deal on the last card. I agree it's good to have a nice spread of cards. Geforce 1060/1070/1080 Ti's are still good at Ether and great at ZEC/LBRY etc but kind of slow compared to Vega for Ether/XMR anyway. My hydro bill is usually between $750 - $850 CAD/month. I don't have a large set up by today's standards but it's nice to save a bit on heating costs in the Winter months. Summer sucks at my place as my AC can barely keep up. I allow in as much fresh air as possible (even in the winter) but it would be ideal to build a mining shed with proper electrical etc. Perhaps if I quit my day job I'll work on this but I'm leery investing too much in mining as POW is an antiquated model and eventually will likely go away. If PoW doesn't go away mining will naturally move towards free or almost free electricity sources which I don't have access to.
