I'm building 2 rigs i bought 6 rx 470's for my first rig should i buy r9 390's for my second rig ? Less used r9 390 second hands with warranty cost like 255-265 dollar in here(these cards used 2 month without oc) and rx 470's cost me 235 dollar. Any tips ?

Power usage is not the same. If you are not paying for power then 390 are the best. Else the RX470 is better. Which brand did you get? I read that msi and PowerColor is highest sols if you do the memory mod

I got rx470's from xfx and if i will buy r9 390's from sapphire nitro. 1 rig will run at my home other is probably gonna run at university's lab up to May 20. So I'm thinking about placing r9 390's to university since electricity is free and they will give nice profit and also teachers will be happy about showing it since no body in the school isn't know neither blockchains nor crypto currencies. And also I'm curious about psu for r9 390's psu or psu's gonna cost me too much i guess.

I still suggest going for the rx over the R9. As it has a bigger change of be useful in the future if you are forced to mine at home. Your lectures might not be so happy with the idea if they feel the heat the R9 will produce.

Thanks for your tips ^^ I will rethink about it btw is r9 390 produce that much heat ?

If your electricity cost is more than 0.15 to 0.2 dollar/kWh, it is better to buy the RX 470 or 480. Otherwise, buy the 390.

My electricity cost nearly 0.12 dollar/kWh Thanks for tips mate

Does the RX 480 4gb have much of a difference than the 8gb version?

There is a 15 mhz diffrence atm but in the future it will make more diffrence i guess.

[Altcoining]

A10-7860k  bit over 11/s
Not going to reboot the machine just to see if it's at 757 Mhz or 800 clock. Memory is DDR3-2166.


Not exactly impressive but I get a bit more out of it than on Gridcoin.

May i ask what the point of mining at 11S/s is? I mean, that's not even going to break power cost...

 1) The GPU side of a A10-7860K only uses about 15 watts.
 2) I'm in an uncommon situation on my lease where my power cost is fixed (as long as I don't run it up a LOT) due to why I ended up where I'm at right now.
 3) 11/s might not earn a lot but it's still a bit over $3/month right now.
 4) I'd be running that GPU on something else anyway, so the power usage isn't going to change even if I WAS paying for every watt specifically instead of generally.
 5) That rig also has a HD 7750 in it, so the total for the rig is almost 60/sec (it also has 2 GTX 1070 doing something else).





 As far as the 4x 280x rig - is the GPU 0 on a 16-bit PCI-E slot, or perhaps a PCI-E 3.0 while the others are on smaller/slower PCI-E?
 We need MORE INFORMATION to make an informed guess as to what the issue (if any) is.
 Among other things, is it more than a couple percent faster?

I mean, to each his own.

The R9 390 is a high end card with 512bit memory bandwidth and 2560 core processor. It is good for computation.

4x shappire R9 280x vapor-x GPU 0 always faster than GPU 1 2 3 ?? memory swap 40 gb have 3x bios 015.42, elpida 1x bios 015.41 hynix. Does anybody have an idea?

You did not post the clock settings. perhaps gpu 0 has better clock settings than the rest.

use asrock 970 extreme 4 windows 7 + 2x pci-e powered risers for the small pci-e slot
all stock, can not use any amd tool, it says driver not installed.... Driver install many time, ok in windows. use tech power gpu z
amd monitor no info  

windows 10 the same, slower speed for all gpu,s gpu 0 faster, no amd tools

amd driver 15.12 not possible to install stays on 2%
missing windows update's??? or anything?    use 16.10.3

GPU clock all the same




No info

Its fine. hashrate are usual with your clocks settings.

Plug monitor into the card. Or just disable intel gpu (works for win10).

[bardacuda]

do you have a monitor connected to gpu0

Yes. It goes black.
I plugged in a Kill A Watt meter, the PSU is 650 watts, and it's only drawing 350 from the wall mining zcash.

Wattage rating means nothing. What is the brand/model and how many amps are on the +12V rail? Also, are you using risers? Are they power or unpowered? USB or ribbon?

Al will depend of your electrical cost. Higher it will be, higher I recommend you to prefer the RX 470s. With the price I'm paying, that's the one I chose.

SAPPHIRE NITRO+ RX 480 vs MSI RX 480 GamingX?

I have both and would only buy MSI again due to ease of programability, noise, max output and heat.

* 6 MSI RX470 X 4gb GPU RIG
* 1120 H/s (186 ave h/s per gpu)
* 880W at the wall
* 1.27 H/W (Hash per Watt)
* Settings = 1500 strap, 1900 mem, 1300 core.

Although, If you can get good pricing, I would go for the MSI 480 4gb.  The MSI 480 8gb is usually out of the price range to be efficient for the output you will get.

Thx for the tip how much did you pay mate ?

These are good stats bro thx for tips. Msi's graphic cards surely stable imo but i don't like the brand and they isn't gonna do rma for international products because of this i choose xfx.

Hello . Since i started using Claymore 8 i got 65 H/s on flypool . Don`t know what happend but since today i only get 55 H/s . I`ve read the earlier messages about halved shares on flypool. But Hashrate is different from shares right ? Any idea ?

No. Pool hashrates are calculated by shares.

I've got 6 8GB RX 480 reference cards in a Windows 7 rig.  All on stock bios.  Getting about 185 per card on v8.  Every time I go into Wattman to change GPU core settings, even just a little bit on 1 card, my computer immediately blue screens.  It does this even after using DDU in safe mode and loading the latest drivers. Anyone having the same issue?  I've tried everything I know, but no matter what I do, it doesn't work.  Any suggestions would be great!

How much RAM do u have in your rig?
Have you increased virtual memory in Windows to help handle the load?

[xeridea]

sometimes when i touch my cards it reboots. I think the miner does it when something is not well connected. Did u try to put this in your config file?

"-r -1"  It will disable reboot mode

It seems like turning the fan speed up was the most stable.
But i'll try -r -1.
Thanks again.

Edit: Crashed with -r -1 on normal settings.

Super stable with fan speed at 65%...

Install MSI Afterburner and set custom fan curves, I found a few of my gpu's were crashing also at anywhere from 75-80 above.. this should fix most of your crashes I think

Been stable for hours with my fan speed manually set.

You could try downclocking slightly, even perhaps 10 MHz.  Transistors work better at lower temps, but if temp is causing crash, it seems it is at the edge of stability anyway.   75-80 is slightly high for my liking long term for the longevity of cards, but should be fine as long as it is below 80C.  What are temps with fans 65%?

GPU 0: 53C
GPU 1: 48C

I was monitoring temps on the cards, and i think it might be the risers that are shutting off from heat? Because the cards never read above 70c.

53C is really cool for GPU.  It is possible risers would have issues at higher heat due to things expanding, you can try reseating them.  As far as temps, low 70s is about my upper comfortable limit, if it's not too hot outside I set 70C temperature target.  GPUs can run fine up to about 95C, though above perhaps 80C it will shorten life somewhat.

8GB DDR3 1666 RAM and virtual memory is at 16GB for min and max.  Should I buy more RAM or raise virtual memory?

Hi all
Why my shares in zec decreases by double in last 24 hr?
I'm using v8.0
