this is my initial test rig setup at a shoplot which is still running now.
electricity bill is about 800usd +- <- the place is for me to conduct various tests before i move to factory scale.

software cost is only about 10usd/year /rig, you got more can nego for bulk farm rate. <-- worth it if you are running 50 rigs and up, small setup like this one just use free versions, teamviewer, hive, nicehash itself.
Hardware investment for the setup above is about 50k usd. already ROI since this has been running since early 2020. after this it quickly escalate to a bigger picture which is inconvenient to share.

Current hardware pricing is a lot more higher than this.

This one is hosted on a single phased shoplot, one 15A wall plug (usually for ac) can hold up to 3600w (power factor 1).

You can change wall plug to higher amp, or you can evenly distribute out your 60A /100A. Many ways to do and depending how much machine you are hosting, balantly go upgrade if your consumption not there tnb will charge you surcharge of the wastage electricity.

I ran one wall plug (15a) on 2 rigs of 6x 3090 + 6x 1660s. No issues, cable is cool.

You are limited by incoming also, main is 100A then you distribute to maybe 60A / phase or any configuration you might like.

Gpu mining is not like asic, 2 x 6x 3090 rig = 1 asic consumption.

Or 4x 6x 3070.


you need to know what you are doing or consult with a specialist before spending any money.

gpu z or open up the card.
the last 0 has been replaced with a 2, so we're now looking at GA102-202.

Yes, dell cannot sell you LHR. reutn and refund means your 7k is with dell to roll for x amount of month, if you buy a card with the money already 3/8 paid when you receive your 7k
Or more since yesterday panic selling the profit surge 300% yet to back to normal still better than earlier.

If the cost of acquiring 2 card is the same as acquiring 1x cmp or equivalent card, yes this would be the case. or just buy team red, difference for 6800xt and 3070 is about 25% cost to cost.
Prices in huaqiang bei is collapsing fyi.

I ran 18 cards on one wall plug, now avrg 12 cards per wall plug. It's safe, 18 is a little too much if your cables are thinner than 75mm. <-- I purposely over kill to try.

12 cards on 1 wall plug with a surge protector and overload indicated apc 8 plug now. <-- running w/o issues.

FYI residential is always more expensive as max tier consumption is 0.57 compared to shoplots 0.5 or less, depending on which tier.

If you rent just need to know which is which, don't need to upgrade. I runs on my shoplot warehouse so it's ok for me to do electrical upgrades since it's self asset.

Chia mining, do you like lottery?
If yes by all means go for it, I do it because I got server pc and workstations to write off, put them to use to try only. I won't invest in a new rig for it.

lol for gpu mining since its so quiet i got put in malls before same .51 cents, got free centralized a/c, security. Nobody will suspect anything.
put mining rig at real mining sites makes the cards really dirty in a month, even with water cooling cleaning the rads is a tiring job. everytime you blast the dust will be absorbed by your gpu lol.

Yea that one, its cord quite thick, so you know if you overloaded just remove one plug or two. you cannot plug all 8 sockets full, most utilized also 6x or 3x depending on psu setup. i build with 2 psu to lessen the load, last time 1 psu the titanium ax1600 like hot potato. now with which ever psu as long as enough VGA for the rigs and both psu performs at half capacity.

Night time switch on your own A/C. Cheap mall better be careful, some electricity cannot support enough, so you might be mining at slight profit.
Hot and stuffy is because of your layout and thermal control measures, hot air always travel up.
Another point to be taken care of is dust control on accumulation on your gpu heatsink. i have clean them every 3 months with compressed air.

Sure why not, as long as the office space has ok security just go with it. i am mining in vacant office space also since office market so bad very hard to rent out haha

cards look from overseas, 3080 about RM 5 to 6k per piece only. need to commit to moq.
i only source for local in my initial stage, now and then also get some local stock to support local vendor other than that mostly consist from overseas, got to swim upstream for cards. down stream cannot supply enough.





Looks like a thermal throttling at vram to me, download hwinfo to check, upgrade your thermal pads and paste.
try take out and mine on other case, and bump the power to 220w and slowly draw down, vram also slowly increase, dont one shot 1200. <-- usually for you to do stable 91 mh/s but rather tiring due to manual work of replacing thermal pads very soon.
Best to mine on other case because alienware has more form over functions.

People tend to forget nvida has vram overheating issues, opt for 3090 is because its the only one with vram sensor easier for you diagnose with gpuz, or team red they can check junction but with lower hashrate.

No, nvidia cards are notorious with vrams temp. especially 3080.
3090 can go scorching hot since it can oc for over 400w, 3080 can go over 300w on the card, providing very very good performance for both leaving amd eat dust.
That being said, thermals are pain to manage, mainly i have them submerge under water. air cooled units changing thermal pads and paste every 3 months or less to maintain hashrate above 88mh/s.

Centralized a/c room also die unless you runs it in a freezer or multiple a/c units. a room with 24 > x 3090 / 3080 with a/c is like a sauna room.
whereas 3070/ 3060ti is better.

have you seen how thick of the heatsink are the top tiered 3080/3090.

I've had gigabyte fan 100%, gpu temp 50C and Vram over 100C causing performance drop in both mining and actual usage. Xtreme version somemore

not that hot with proper management, about 27 to 29C, rainy days are better.

Yes maintenance is required, hard work if you do it yourself. got to have various systems and sop in place to have it running at optimum condition.

Its easy money, infact only hurdle is capital and liquidity management, the rest are easier than it looks.

1 years and 8 months from the 5700xt till 30 series,

Non gpu died till now, so far so good, a lot of lesson learned along the way. Asics are more prone to breakdown compared to GPU. and bloody loud too.

On current hardware climate and crypto pricing, we just have to pray the storm would settle soon so we can continue to harvest money on the side.

apparently so, but not back to msrp.

You decide, willing buyer willing seller. fyi LHR might or might not drive the non LHR variant up, but it will not be cheaper than non LHR. most likely will go on par, market needed some time to recover.
say people buy 7k takes about 10 months to break even, you do the maths and nego with the seller.

Bulk players cost for 3070 is about 4.8k or less on current timing, 5.8k or less for 3080, 7 to 8.5k 3090.
profit driven enterprise maybe will sell slightly markup or about cost or lower. longer player avrg cost is about 3k +- per 3070, 4k+- 3080.


Better dont buy inflated price GPU, if its within your means or buying purely from mining profits, just go for it.
Current eth profits are about 1 year ago pricing when its 6 months to breakeven on launch pricing. current pricing will take years to break even if you only mine and do nothing else.

Asic on the other hand can totally consider the newer variant

unlikely so, unless eth drop below 400usd, then maybe people might be selling their 30 series, its still ok money considering can make 1k usd still for 6x gpu rig monthly for current pricing.


Miner will either exit after eth or mine other not so profitable coins, regardless there are still money to be made.
It is still good when you make money by switching on electricity only. Maybe older cards will be disposed but not the latest ones, who wants to make a loss on capital when you leave it there will be still profits in the end of the day.

you see people dispose only those machine when you turn on making a loss or older cards which is un mineable due to dag file size. unless 8gb is being phased out soon, else rarely people will dispose the cards.
not so profitable coins generate more heat compared to eth, thats why its less desirable.

most asic available for cheap are those making a loss, even i got renewable sources i wont turn them on also. too much of work to keep them relevant.
Lets monitor how this goes and hopefully it turns out well for all, be greedy when the whole world is panic selling lol.

i think for now just buy and mine la what ever card without the lhr you can find, since we dont know how the is the lhr and Nvidia whether want to lelong their cmp cards since eth mining days are shortening by the clock.

Because stock is king, dont get into situation when you got money and no cards to buy, or got cards also not enough to build a 6x or 8x rig.

Maintain a healthy balance sheet and liquidity, continue to mine until nothing left to mine lol.

alternatively get into chia mining or build monero mining rigs lol <-- it makes sense if you have quantity. ROI in a year not included monero value rising, since regulation bodies will be targeting crypto, privacy tokens will be flourishing very soon, depending how efficient are the goverments shaking the landscape.

Monero is better than the underground banks btw, even ccp dont know how much money is in and out everyday.

Where you got it ?
a little steep in my context.

can, see what you want to mine lo.

nice, palit 3060ti please replace thermal pads and paste for better performance and temperature.
can get steady 60 to 61 mh/s @ 120w. and to turn off the led lights also will boost a little bit on efficiency.

dont worry about pricing, as long as your rig is always on the money is coming back

Mine running about 58C without changing, after changing about 51C.

start with CC -502( or directly start -200) and adjust up mem clock +750 onwards
i usually do power reduces to lowest +5% and gradually up. that way usually you will start with 58/ 59mh/s, will take you about 10 mins to fine tune. <-- if you dont have a lot of cards to do.

If you are doing all 6/8 cards together, use paid versions of hive, awesome miner to let them self optimized / self oc.

OC and undervolt by yourself is the best since not all silicon is the same, there are slight variance each hence differences in efficiency. best i am doing with 3070 and 3060ti is 58%. highest for gpu rated for efficiency and thermals. junction point about 70+-C Vram i estimate about there also.

Do understand more about energy first, people who invested too much isnt affected as not much malaysian operators in iran,
Iran tariff is super cheap btw. Players are flocking to Kazakhstan from Iran to balance out. Some planning to US/ Canada since Elon said they will invest more in renewables.
Things might change if someone going to invest in Iran, and get a new dictator to suppress the trouble makers there.

How much of a free fall are you expecting ? new asics are almost sold out as soon as they are on shelves. Gpu the same.
Mining difficulties are climbing as more hashrates is available, infact more country to close down crypto mining means easier for you to mine for profits.

Iran themselves profited for more than 1 b usd on selling electricity, they just want to catch people stealing electricity to mine so they can balance their coffers and build better infra for it. Tnb makes so much more money than iran on tariffs to tariffs.


Its a no brainer game btw, prices commanded is more expensive than you buying from tw on shopee lol.
Both also no warranty to cover.

Ethermine, for slightly better payouts about 1 to 5% depending on days. To be knocked off with high gas fees.

Phoenix miner is still safe to use, check with their developers.

Binance pool ping is high, no matter which port is the same. They might be running geo latency server, maybe some of you has ways to reduce pings do share. They offer the best convenience due to pool withdrawal to exchange or to pop.

Nicehash has its highs and lows, I used profit switcher based on a few rates prescribed. So it will switch between binance, nicehash, ethermine.

If you mine long enough you average down, payouts is really similar. In the end of the day your hash rates determines your payout.

Unmineable, technically is mining eth, monero and convert it to the coins of your choice on a terrible exchange rate.

Unless you do it for fun, for profit better stay away from it.
And yes it will not apply oc profile also, you need to overclock your gpu/cpu yourself to prevent hardware failure.
