Best efficiency settings for Radeon RX 480

[pikachuy]

I've been testing a lot lately with different wattman settings and so far, this is the best I can get. My main goal was to lower the power use as most as I can without impacting the hashrate too much and also lowering the heat and noise. So I just want to share what I have been using now to help others.

I have 6x XFX 480 4gb models. At first, I flashed them all to 8gb, but I flashed them all back to 4gb, due to the 4gb having 1750 memory clock instead of 2000 memory clock, which will lower power usage without impacting hashrate that much (probably due to better memory timing straps).



I just change state 7 to 900, voltage for gpu and memory to 800, power limit -30%, and change the fan speed and target temperature to my liking's.



Here is my GPU-Z showing my settings stuck even after flashing from a 4gb to 8gb and back to 4gb.



Here is me running Claymore 4.7 with ETH mining only and showing a stable hashrate of almost 24 mhs per card with GPU-Z graph.



Here is my whole rig power usage with 6x RX 480.


So far, I'm pretty happy with the results with the whole rig only needing about 670 watts at the wall.


If anyone else can figure out a way to lower power usage even further and still stay close to 24 mhs per card, please share. Thanks.

4.69w/MHs, good !

Actually, 12.32w/MHs with my poor 280x rig

a gtx 1070 is 3.7w/MH and 1060 will be the same or a bit worse, like 4 ratio

1070 is more expensive yes but who care you can sell it 3 months later and losing nothing

Lets say both rigs hashes 143 mhs total.

If gtx 1070 gets 3.7w/MHs according to you, then that power at the wall would be 529 watts.

The rx 480 at 4.69w/MHs will be about 670 watts at the wall.

That is only 141 watts difference. I don't think the start up cost of a (6) rig of gtx 1070 would justify the 141 watts difference when compared to a start up cost of a (6) rig rx 480.

For me, a faster ROI is better when less capital is spent to start off with.

i agree but you need to account the resale value, and almost no one mentions it when talking about roi, but it's a part of the roi itself

in fact the real investment on which you need to roi is the difference between the price at which you bought the card and the one at witch you sell them later, not the initial investment

also you didn't take into account the scale factor, having 3.7 at 24MH is different than having 3.7 ratio at 27MH

the 1070 does 3.7 ratio at 27MH at the very least

you sound stupid dude must be a lifer NVIDA or employee or something just shut up rx 480 is better for Eth and its not even close, now if youre saying you want the 1070 for mining other Algos thats a different story but
your broken record act is getting annoying.

Wrong also btw on resale , rx 480s are hard to find actually harder to find than 1070s right now , I checked Newegg,Microcenter and Best buy and they dont have any rx 480 for sale but guess what they have 1070s for sale by the dozen.

Checking ebay the rx 480 lowest price is like $300 usd so you can actually make a profit if you want reselling them

do you even research any of the BS you spew ?

Anyways back on toppic i have a rx 480 rig all 8gb , everytime i change the settings in wattman i notice they revert back
and sometimes crash even, another thing i found is turning the power limits below neg 15 reduced my hashrate by alot so i cant do that.

I noticed sometimes the wattman settings get funky when tweaking, so I have to reset the settings back to default everytime when I want to create a new config and also restart the computer. Give that a try.

Also, I noticed when I try to change wattman settings on the fly while mining, it goes wack, so I only change it when not mining and then do a full computer restart.

If you want to lower your memory clock to 1750, you need to flash your 8gb to 4gb bios because the 8gb bios is locked at 2000 mhz for the lowest memory clock in wattman from what I can see.

Edit: Plus, there was no need for that 8gb for eth for now, so I figured it should save some power by the bios disabling 4gb and having the memory clock to 1750 instead of 2000 mhz.

Thanks for responding , I dont want to gimp my 8GB cards I like the higer hash rate , I overclock them all to 2200 mhs , I notice that i can lower the wattage on the memory so thats how I have been reducing power use
on the higher memory overclocks.

I suspect the reason the 4GB cards are capped at 1750 is more because they use lower qaulity chips not due to the amount of on board ram

I can get up to 27.8 mhs with the memory overclock and thats stable, its when i try to reduce the core wattage and the core frenqency i have problems, and eth only needs around 900 or so like in your settings
but whenever i set the core freq lower it resets to either really low like 700 ish or just ignores my manual frequency setting. 

I might try a fresh install after i test the new rig im working on right now.

[BeastLeeX]

Have you tried any memory speeds in between 1750Mhz and 2000Mhz? I wonder if the timings change anywhere in the range?

you didn't post any sense in your post so why i should bother? resale has nothing to do with the difficulty to buy a 480, do you know what resale is? it's when you sell your HW again

so now tell me what resale has to do with the limited stock of 480? utterly stupid no-sense

it seems that you misunderstood as usual like many other, i didn't imply that you can not resale your shiny 480, but that the initial cost count nothing because you can resale for almost the same price, so the fact that a 1070 cost double of a 480 count exactly zero, do you understand now?

only thing that matter is efficiency and a 1070 has a better efficiency in all the algo, and also yes there isn't only etheruem out there so another reason to avoid amd which is private and all the other relevant algo are not optimized

Youre just burying your self more .. If i am buying cards to mine i intial cost factors in since no one has unlimited funds.  One 1070 hashing at 37 mhs is not as good as two 480 hasing at 52 mhs.

In regard to other Algs two 480 will still mostly be better than a signle 1070 and as new cards they will hold thier value just as well as a 1070 so the inital investment is a moot point.

All that matters is hash $/watt the fact you can buy far more hash rate with 480 cards than nvidia.  Add in the fact there is no Dual miner for Nvidia and also the fact that its only on Liniux you get high hash rates makes it even a worse card to pick for mining right now.

[adaseb]

Its pretty impressive I must say.

Basically its twice as efficient as the older Tahiti based cards which are 9-10W/MHS.

All we need now is some aftermarket manufacteurs with better cooling and 8 pin connectors.

yes 37MH is lower than 52MH but 52 MH consume much more than 37MH, basically double, now scale this up to 100 gpu, and you are not considering the huge loss in electricity which you will pay 1 month later of your purchase

now you will argue that you have free electricity which is bullshit to me you are probably stealing it and it's not the normal for the majority...

also remember that due to the less MHs a 480 need more rig to have the same hashrate of one 1070, those more rig(more cpu more MB ssd power supply which are all expensive things that do not mine), are equal to more money invested, so you are not even saving anything in the end

p.s. yes none have unlimited funds, like none have unlimited electricity so since i can consume half of you i can potentially add 2x the gpu, so takes which suits you more

[virasisog]

I agree with Amph. I have limited power capacity in my house, so the efficiency is more important to me.

[ashkanb]

if 1070 consumes less w/Mhs & is more efficient hashing eth, it's more efficient; there is no point arguing about that!

i guess in the end both 480 & 1070 have their own thing going for them, personally i don't care much about w/Mhs; electricity's dirt cheap for me!
since i'll be upgrading my current rig (not paying for a whole slew of other parts), the fact that currently eth is what gpu mining is & that eth mining is going away fast, i'll most likely end up with whichever of these two i can get my hands on first!

lastly op, thanks much for the op, much informative & well executed!

[Amph]

consider also that the 480 is bad at both lyra2v2 and neoscrypt until someone optimize it, and those algo are more profitable than eth

you have 2 good algo missed, basically the 480 is only good on one algo, which is very bad

so i see really no reason to purchase one

Dear Sir,

Could you please fuck off from the thread about efficiency settings for RX 480?

Nobody here is interested in 1070

Thank you!

I've been testing a lot lately with different wattman settings and so far, this is the best I can get. My main goal was to lower the power use as most as I can without impacting the hashrate too much and also lowering the heat and noise. So I just want to share what I have been using now to help others.

I have 6x XFX 480 4gb models. At first, I flashed them all to 8gb, but I flashed them all back to 4gb, due to the 4gb having 1750 memory clock instead of 2000 memory clock, which will lower power usage without impacting hashrate that much (probably due to better memory timing straps).



I just change state 7 to 900, voltage for gpu and memory to 800, power limit -30%, and change the fan speed and target temperature to my liking's.



Here is my GPU-Z showing my settings stuck even after flashing from a 4gb to 8gb and back to 4gb.



Here is me running Claymore 4.7 with ETH mining only and showing a stable hashrate of almost 24 mhs per card with GPU-Z graph.



Here is my whole rig power usage with 6x RX 480.


So far, I'm pretty happy with the results with the whole rig only needing about 670 watts at the wall.


If anyone else can figure out a way to lower power usage even further and still stay close to 24 mhs per card, please share. Thanks.

These are close to the best settings on all of bitcointalk (and I've tried the all, along with many variations).  Admittedly, I slightly tweaked this, and am doing 2100 on memory, with a bit more voltage and getting 25.5 per card in my farm.  I brought power consumption down 40% doing this - and my fans speeds are 50% less.
