a4000 are very good in the proper server rack.
i am going to try the a2000 soon.
https://minerdude.com/product/pre-order-minerdude-x12-xtreme-12-gpu-smart-mining-rig-pre-order-delivery-late-aug-early-sept/i have seven of rhe racks above
i had eight but sold one.
12 a4000 in the rack above are great.
i got in on all of the above at better prices than right now
12 x 1250 = 15000 usd for cards
1 x 1000 = 16000 usd for a 12 card rig doing around 680 mh pulling about 1600 watts.
you would be lucky to build that rig for 19500 right now.
I have over 7gh of eth hash
but we have very good power prices we can invest and have 40 a2000 coming
they should do 1.6 gh
with luck the team will have 9gh of eth hash online in under two weeks.
do not think that a4000 are good for gaming.
also do not run the max watts of 140
set to 115
140 doing 61 mh
115 doing 58 mh
pretty easy to understand why we will do the 115 watts.
At the moment we have 165 cards all from april 2020 other than 4 1080ti cards.
of all these cards we have only had 2 rma which were in a two card rig for mining and gaming.
i think the mobo shorted.
so pushing the shit out of cards in my experience is not cost effective.
remember i can risk more then many others due to power deals and solar arrays
45k array online averages 9 kwatt 24/7
110k array online averages 22kwatt 24/7
350k array be online this spring it will average 70kwatt 24/7
about 101kwatt of basically “free” power . it is complex to describe it as free
but i am a degreed accounting guy and calling it free is kind of accurate even though it was about 1,000,000 to build those arrays.
most miners simply do not have power access that allows for risks we take.
