Here is XHV block reward on CryptoKnight https://cryptoknight.cc/haven/



What the hell is this 33% transfer fee!!   They are only paying 15 XHV block rewards to miners. 

Its summer, and its too hot to run these cards.

They were used sporadically to mine monero.  Less than 6 months old.

They are reference XFX, 8gb samsung memory. Vega 56 and Vega 64 bios loaded, just flip the dip switch.

You can check my ebay feedback under
same nick.  I accept most crypto.

PM me an offer if you are interested.

I have 14 MSI RX 470's from Nov/Dec 2016 which are running 27-28Mhs ethereum.

I bought 4 more cards from newegg last week, and I had to reduce mem clocks on all to get them stable around 25.8-26.2Mhs ethereum.

On my older cards I'm running undervolted memclocks anywhere from 1920 to 1980, along with underclocked and undervolted cores.

New cards are stable around memclock 1850 to 1880.  No correlations between ASIC qualities (as reported by GPU-z).  Some of these new cards report 79.9 ASIC, but they are shit.   Could I be that unlucky to get 4 for 4 crappy cards?

Not sure whats changed @ MSI, but I'll be returning all 4 of them....

Okay,   I have 12 RX470s running.   Lets assume I have these mining scenarios.. 

XMR @ 7890 H/s        @ 665w
ETH @ 312 H/s           @ 930w

Using current rates...

XMR will earn $10.66 @ day and cost $3.53 in electricity = $7.13
ETH will earn $11.94 per day and cost $4.91 in electricity = $7.03   (-$0.10)

Pretty close right... So my coin picker is going to tell me to mine XMR, but I'm seriously questioning this given that its winter here right now.

Lets assume the heat my rigs produce are worth 30% as supplemental heat credit (electric bill goes up alot, gas bill goes down a little).

XMR will earn $10.66 @ day and cost ($3.53*70%=$2.47) in electricity = $8.19
ETH will earn $11.94 per day and cost ($4.91*70%=$3.43) in electricity = $8.51  (+$0.32)

So ETH can earn me a bit more in winter because it had more usable watts which 30% of them converted into heat off-setting the need for extra gas.

So my question is, does anyone have a good idea or a guestimate as to what the supplemental heat efficiency percentages really are?    I've read electric heaters are pretty efficient, and thats really what we have here.  And placing mining rigs in rooms you use most can help even more.. (http://cadetheat.com/blog/how-efficient-are-electric-heaters/)


In the summer, we could do the same exercise, and instead of heat credits, you apply cooling penalty..  for consistency lets just say thats also 30%

XMR will earn $10.66 @ day and cost ($3.53*130%=$4.59) in electricity = $6.07
ETH will earn $11.94 per day and cost ($4.91*130%=$6.38) in electricity = $5.56  (-$0.51)

So if XMR and ETH produce similar rates, it makes more sense to run XMR in summer and ETH in winter.   Or move rigs to garage and put ~150w box fan on them which would cost more like $0.40/day instead of $1.06/day for extra indoor cooling.

So, what do you think the electricity to heat efficiency of a GPU mining rig is?   And the alternative, what is cooling penalty?
