With just 10 pieces of 3090s you are already at 1GH on the Ethash algorithm, why aren't people doing this instead of having so many GPUs around, taking so much space and having to use more risers and more motherboard, why are people not going this way?.

it is called density, i'm one of the miners here who likes density. actually when i recommended 3090s for density before the bull run and during its release, there were miners here who are against it.

now my next recommendation is preparing for gddr7, and try to maximize density again.

Hmm sorry why should i buy a gpu for 2000€ or now for 1800€? Because it has over 100mh? Sorry this heat problems with GDDR6x, the efficiency is also not the best.
I prefer RX5700 - consumes around 120w and do up to 55mh - for me the better W/MH ratio
No many bought AMD Vega7 3 years ago - they do 100mh at 200w for 700€ (at the release), much better than the RTX 3090.

I also have a couple of AMD 6600xt running at 0 - 25% fan and temp is around 55°C, so nearly noiseless and really no heat. Different person prefer different things, and not all have the money to start with GPU´s for 2000€.
When i see the market - if you want a gpu that make over 2$ a day you must pay around 600€ - in 2017 we bought GPU´s for 200€ with the same reward. The same thing happens with asic - an s9 cost me 2000€ in 2017 and it make up to 20€ daily. Now miners cost 10000$ and make the same money.

The reason why people buy less powerful GPUs are

1. They can find better prices and discounts for older GPU compare to an high end GPU.
2. They gets a higher hashrate out of smaller GPU compare to spending thousands on a high end GPU.
3. Heats are the major problem of these 3090s and that's one of the major reasons why people don't want to use them for building mining rigs.

I rather pay $700 for each RTX 3060 Ti/3070 FHR cards than get one RTX 3090. I own a few 3090s but they were bought around the $1700-1900 range months ago but they wouldn't be my first choice especially before LHR was introduced. The memory on the back of the PCB is crap too if you don't add heatsinks or actively watercool them. Have fun with 100c+ vram temp and dead 3090s down the line.

3090 Ti on the other hand.. definitely a nice card.

price? heat? efficiency?

amateurs..(you all can handle those issues if you know what you are doing)

3090's ROI'd many times already from the date of my recommendation..

you all complain because crypto prices now in relation to mining is not that great (but great if you know..you know)  Wink

There's a lot of situations where I can think the reason people not chose RTX 3090 instead of any other cards

Here, in my reality, my country, my situation:

It was hard to found 3090 and when you found one, the price did not match the expectation, so it's not available most of time
It's easy to resell cheaper cards then 1x 3090 (remember, my country)
The price per mhs of the 3090 are higher than other cards
I like to have a mixed rig, I can have flexibility

This were my reasons, and there's people who can't afford a single rtx 3090 but can buy a cheaper one, and after some time buy another card...

Another example, most of 3090 here are from brands that have bad RMA, the good ones like Galax, Asus or EVGA were more expensive

Expectation?

You have to buy at 1400$ before it got to 2000$ and above.

You have to buy before the bull run.

You have to know your brands and specific models.

You have to know how to dissasemble and replace thermal pads.

You have to know to tweak.

You have to know your electricity cost.

You have to know (insert others things that are out of topic but essential as miners)

Resell?

If you ROI'd your 3090's several times over, sell them now at 1000$ each and still be happy LOL


Again..amateurs.

Expectation?

Hehehe, 3090 at the peak costs here more than 3000 USD, so it's unreal for most of us here to buy a card at that price
I bought some cards but not a single 3090 because as I said, when it was availabe, it costs more than I expect

Here we receive the cards after US and Europe, and the first batches are always more expensive, so impossible to get one at decent prices, and the scalpers got a lot of cards too resell

Another thing to know, the RMA of almost all brands are really bad, we don't have local warranty for Zotac, EVGA, Sapphire, Powercolor and Palit for example, the store where we buy have to give some warranty, but we can't open the card to modify.
The only brand that I know that accept thermal replacement is Galax, but if they judge the card is bad due to your service, they can refuse your RMA.

A rig with 5x 3090s with 575Mhs and a EVGA Supernova 2000w is a dream to have  Grin Grin Grin

One reason is they are starting with enough money to build a rig smaller than what you recommend. I too started from a single GPU back then until it became 5 of them. Another reason is the supply, there are scalpers around in every corner of the earth, new stocks are always sold out or if available it is higher than MSRP. There are lots of reasons that you cannot do what wanna do, unless you buy it from scalpers in order to build your dream rig, or buy it used and feel it's remorse later on.

there was a window of opportunity to buy before the chip scarcity and the bull run, nvidia release may not be exactly the same day/s around the world but they were released globally.

if a card mines for months up to a year (store warranty period), the chance of it being defective are very low, so modifications (warranty being void) is worth the risk...aaaand here comes your "mining conditions/environment" if you can't/or don't know how to cool your gears well enough... then i call them amateurs.

in mining you have to know the "tools of the trade".

3090 and 3080s will give you lots of headaches starting from heat issues and low hash rates down the line, if you aren't ready to spend money on extra cooling, copper pad mods, higher-end thermal paste then stay away from these cards, I know it makes sense to have limited cards with higher hashrates but not with 3090s.

in mining you are always ready spend money on anything because you are earning and those extra expenses are still covered by profit.

if you can't spend extra or not earning enough, then re analyze your mining venture.

When you have experience mining on RTX 3090 graphics cards, then you will not ask such questions.You need to buy expensive closed cases, make ventilation, change thermal pads. And you will all be in trouble in the summer.
And instead of this, I’ll buy 20 cold 50 MH video cards, let’s say Radeon RX 6700 XT.

I would do the same and the price of such card is not even expensive anymore,sounds like one of the wise choices for 47 Mhsh for card for sure with some new versions going up to 50 Mhsh but  47 Mhsh is a sure thing at 120 watt per card.Three of such cards consume the same or almost the same wattage as a RTX 3090 but have better hash rate in total and of course they run really cool,not only this but all the 6000 series,I own the 6800 XT and can confirm with 35% fan it runs at max 63 degree celsius in 20 degree ambiance temperature.

Every crypto miners have their tastes when it comes to graphics card, I as a person do not like big GPUs like 3080 and 3090, I like something more efficient like 6600XT or 1660 Supers, they make less heats and deliver good hash rates per watt.

I have 2x 8 card 3090 cases.

I have a 3rd case.

use this case

https://minerdude.com/product/minerdude-x8ultra-plus/


with 8 of these.

nice gear.

good rigs.

Because 2x 3060ti gives more total hashrate, are cheaper and use less watts than 1x 3090.

There is a problem somewhere, your 3090 should give you 120-130MH, if you are getting less number its mem a temp issue, a friend I knew has one 3090 thats doing 113MH and he lately changes the thermal pad to copper cooling and wonders happened.

Very high price. Even if I needed a closed case, I would have assembled it myself from analogues no more than $ 650. But if they calculate the cost of PTX 3090 video cards, then for a similar price you can get a larger hashrate.
