Quote from: LoneRangir on July 13, 2016, 06:00:20 PM

Since none of the stores seem to have 480s in stock, I've been looking on CL for used items. What is the expected hashrate of an R9 390X, and power draw? Worth it at $200?

I get 58mh for 2 r9 390s

I spend 500 watts.

I get 73 mh for 3 rx 480s

I spend 430 watts

Kilo17 has some new 480s he is an honest guy

I would spend the extra for the 480s and save the power.

But my power is not cheap for my eth rigs.

If you have really cheap power the r9 390s may be better. Your power over 11 cents get the rx 480 from kilo17

What are you thoughts on using a R9 asus nano?

I am new to building a rig. I can pick the card up for $425 CDN

I thought that was a pretty good price.

Thanks in advance

it does around 28-32 mh tops. but it is thinner and use far less power.

I would say its okay to use. I have three of them.

I have a few r9 390's they do the same hash but use a lot more power.

What are you settings for R9 nanos, I am getting about 26.5 MH/s at stock setting using Claymore's dual miner ETH only mode ~180 watt.

It is a good question - if mining depends on memory frequency most probably you will not get more MHs compared to R9 390

But if miner uses number of GPU cores - you may get a substantial increase in output

Lets wait for Gurus

I can also pick up 2 R9 290 for $300 CDN for both

You need to try each one going from lowest to highest voltage until its stable. One of my 290 is very stable the lowest voltage, another one is only stable at the highest voltage. Check your ASIC quality in GPUz

Thanx for trying to help.
For my home computer , mining with two gpus , I would like to get the less noise possible , so I need the lowest temp , that imply lower voltage I think.
Could you confirm my understanding in the reading of the files name ?
=> MBA_C6711101-100_K2_AGR_STILTMP_V48.zip (DPM7 - 1.1000V) is the less voltage available.

That would be correct - IME even the highest-voltage Stilt BIOS ran a TON cooler than the stock bios, I've not had enough time to play around with the others to date.
The x.xxxxV at the end is the "default" voltage for that BIOS version, lower is better for cool but too low = card don't work right, crashes a lot, etc - and that will vary quite a bit with the specific card due to manufacturing variation.

Could you help me ?
I've tried another bios , the V40.zip (DPM7 - 1.1500V) but still not very good.
Temperature didn't went down , maybe slightly higher !
Wattage is higher for same hashrate as stock.

When I check voltage with afterburner , my two r9 290 flashed with same V40 bios show different voltage : one close to 1047mv and the other one à 1146mv !
I don't understand why , it's not normal , and maybe the lack of improvement come from here ?

After the BIOS flash, you need to unintall the driver software, and reinstall it, also the MSI afterburner.

are the 470 out yet i can't find them any place on sell and no 480 any place at the price they were at first all most every were i look is out of stock or well over 199 for the 4 gib version . I was gonna try to buy a rx 480 next week with 4 gb or 470 .

edit: this is why no 460 or 470 yet

There’s also the RX 470 "for gamers happy with 1080", while the RX 460 processor is for "eSports, streaming and notebooks", with 470 and 460 only available to OEMs for use in their various products.

it's gonna be a 480 next week may be two i hope, there back in stock by then .

cya

So you mean that if I want to grab some 470 or 460, I need to buy a whole computer from like HP ?

Anyone have tried undervolting stock 480s?

I get about 24.5MHs per card and would like to save on power a bit more.

I dont mind losing 1-2 MHs if I can lower down watts by at least 50-60watts more.

Anyone tried this?

Where do I get this Wattman utility for RX480. Can it undervolt the 480?

Here is the link to Crimson 16.7.2 http://support.amd.com/en-us/download/desktop?os=Windows+10+-+64 . Once you install and open it, click on Gaming then Global Settings. You should see all of your miners and wattman settings for each miner. To lower power limit change temperature to manual otherwise control will be grayed out. It does lower power consumption also hash rate a little bit.

ok thanks hawkfish007 - will try this in a few hours... I am on Win7 currently and looks like for 480's , I have to use the dreadful W10.

I have 3 rigs. Two of them have 6 Sapphire 380x(stock) 129mh and one rig with 4 MSI 380s(slight overclock) 82mh. They do have external fans and are running between 59c-65c. I have the onboard fans bumped up to 65%. I would rather replace the fan than the whole GPU!

This T is quite reasonable. Mine cards are loud - probably will put an external fan

Any promises that DCR will be a potential currency (let say 1-2 bucks per DCR)?
