Your GPU gets hot, good fans cool it though. I have about 1 1/2 inches between each GPU and eight above each rack. I don't need extra fans besides moving air in and out of the room.

well "moving fan in and out" is the same as additional fan.... it prove that the fan alone of the gpu are not enough especially in summer at 30° did you test it ?

in winter the thing is different, there is no problem even if i live my gpu spinning without additional fan and at 40% i get good temp

I've been mining for more then three years dude. Yes I've had a couple summers. You're talking about putting 140mm fans on top of the cards to 'keep them cool'. Fans moving air in and out of the room keeps the room cool, not specifically the GPUs. If you're just keeping the GPUs cool, you don't get rid of excess heat and it builds up in your server room.

The GPUs should be able to maintain their own temperature or they aren't doing their job. That's specifically one of the reasons for buying one brand over another, the cooler.

no not on top, on the front, you know by creating the tunnel effect, without that and 30° celsius on the room it's not possible to have good temp(below 65-70°) with only the gpu fan

Went to whattomine with 970, current revenue & difficulty. 20 on ethash, 500 on cryptonight, 200 on equihash. Cryptonight came on top of that listing, I never believed this day would come.

[go6ooo1212]

you could squeeze 21.7 on ethash / 230-40 on equihash with 970...
I didn't know the xmr score though

Yes you can push them to 22-23, 240-250 and 520-530. But there is no need for that when they do 500 so silently.

[Amph]

yeah and a 1070 can only do 600h, something clearly wrong there

[antantti]

Pretty sure maxwell can't do more on xmr.

1070 can do more than 600, need to play with settings & os.

It's the same shit dude. Changing room temperature is quite a bit different then trying to assist the coolers. You're trying to change the subject to wiggle out of this because you know exactly how wrong you are. You literally have extra fans on your GPUS, whether pointed through the front or on the top to keep the fans at lower speeds, you said so yourself 'so they last longer', because the fans are broken. That is also why you have your fans permanently set at 40%.

This has nothing to do with room ambient temperature and there is absolutely no way you can change room temperature with a little 140mm fan. I have high flow large radius fans going in and out of the room, something in the range of 15,000CFM. For small operations people use box fans in and out of the room, those move once again about 3-4,000CFM. A 140mm fan moves roughly 150CFM. You would need 100 of those to get the same sort of flow I'm getting.  If the coolers were good you wouldn't need to do that.

Once again Gigabyte fans are absolute trash, they fail in 6-12 months without pampering them or babying them, including setting the speeds artificially low and cooling the cards with a different fan, taking them apart to oil them every couple months, or blowing them out every other month. You don't need to do that with any other video card manufacturer.

[Amph]

you missed my point i never said that they were good, just that you can avoid their problems by adding additional fan so they can run at lower speed

but this is not true in winter where you can leave them at lower speed regardless, it wasn't so hard to understand....

So we both agree, Gigabyte cards have shit fans and people should avoid them. Easy, to understand, right?

How could you achieve these hashrate?! my zotac extereme do 18.7 eth ( zotac overclocked them heavily ) and my gigabytes 970 g1 do 17.5

Not trying to preach to the choir here, but this is why we have pay miners guys. Nicehash and EWBF are competing with eachother slowly, but surely for the extra hash on their services. Whether it's a 2% dev fee or mining on Nicehash's service, they're both trying to make better miners.

I'd like to point out that Silenarmy's miner basically fell off the map once he lost interest. He moved and now even after returning he spends absolutely no time working on it. There is a reason you pay developers for their time and effort, because at the end of the day, if they aren't getting paid, they're just doing it either as charity or as a hobby. Both of those are very prone to whimsical interest of the developer. Think about how much effort you would put into mining if you didn't actually get paid and you put the same work into it? Almost nothing? Yeah...

Encourage paid development. As long as it's fair and honest, developers should always get paid so they continue to do what they do. Miners need developers as much as they need mining hardware.


Lets not forget individuals that went out of their way to harp on people for wanting faster miners too. There were plenty of people that either hated on you or would down talk you for wanting just as fast of a miner as Claymore or for thinking that Nvidia could get remotely close to his speeds. Low and behold now not only is EWBF and Nicehash faster then Claymore, they're also more efficient. Getting almost close to 2x the hashrate of a 480, which is about on par with what speeds we should be getting. There are a lot of ignorant and uninformed opinions floating around the forums. They just go off of what they know and like 90% of the miners here are born from Ethereum AMD mining.

well said, this time I agree completely ;-)
devs can be greedy, but so can miners.
we need to find a good balance.

These are my exact thoughts, and this is what I am intended to do later on with my projects

Agree with your points about dev.
For amd/nvidia : amd lacks new high end cards (vega soon ?). I agree nvidia are more efficient, but not significantly faster.

I am mining with a GTX 1080, a GTX 1070 (no longer)  two fury-x, a RX480.
The fury-x is doing 375 h/s which is as fast as nvidia GTX1070/GTX1080 but at 190w instead of 140-160.

For now RX480 are not very good at equihash, but they are efficient at cryptonight (monero): without bios mod but mem OC: 730h/s at around 100w. The GTX 1080 could manage around 640h/s.

Fury is a notoriously power hungry chip, not sure I believe you getting 190w for 375sols. There is a reason Fury-X's come with water cooling built in.

http://www.tomshardware.com/reviews/amd-radeon-r9-fury-x,4196-7.html

I'd have to see some wall numbers before I believe that. Not sure where you're getting your power numbers from, but there is no way the efficiency of Fury is close to a 480. Utilization of the chip would be close to 50% of what it's capable of if that were the case.

If you have to bios mod anything, that's completely out of the question. If you manage more then two rigs BIOS flashing is a huge risky waste of time...

A 480 is a better value proposition then a Fury simply due to efficiency. Like I said before, definitely don't believe your numbers for power usage on a Fury let alone Fury-X, which can use upwards of 350w (450w peak) under full load. There is a reason people are picking specifically Fury-Nanos and then bios flashing them to custom clocks and low power profiles for mining Ethereum (which of course doesn't translate to other algos).

Yes Vega efficiency might be close to a 1070... Maybe, but still not here and wont be for a few more months.

[bensam1231]

There must be some sort of pricing threshold that Equihash crosses where it becomes profitable to start up AWS instances. Like 50% of the hashrate that just magic'd out of thin air on Equihash didn't come from any of the other algorithms.
