Thats because "-dcoin sia" is not a valid option. Try "-dcoin sc"

I have 3 RX580 4GB and they have been mining at 29 mh/s for almost 2 months now. I didn't see a drop nor and increase.

GPU mining wont be profitable soon, save up and wait for FPGA/ASIC. They will be expensive.

The more info you provide, the better.
What OS? BIOS mod? Which version to Claymore? etc...

probably not a good idea to put your full serial number here. You can easily lose your warranty if company A or company I notices their returned card matches a serial from this post.

I would if it didn't void my warranty.


=== Update ===

Looks like the 570 is just plain crap. I replaced it with a 580 4gb, did a bios mod and bam! 27 mh/s (Without tweaking). Time to tweak and see if I can get 30 mh/s.

tl;dr; Don't buy RX570's. Unless you land a Samsung or have the patience to tweak your card.


Thanks everyone for the help
I've struggled 5 days with this card trying to figure a way to increase performance.

My card only has 1 set of memory timing.
Here's my Original BIOS:

https://www.dropbox.com/s/t6zekfi7b2cdu0j/Original_RX570_8GB_Nitro_Plus_Hynix.rom?dl=0

Hum... I tried flashing 1500 strap to the higher timings (even 2250) but when I OC my mem to 2000 on AB, the system crashes. Don't think it worked :S

So I've been trying to mine Ethereum with a RX570 8GB Nitro+(Hynix) and for some odd reason I can't get it to mine more than 20mh/s

My Spec:

Windows 7 Home Premium
Claymore 9.8
Crimson Relive (lastest one) + leaked DAG fix
BIOS mod (strap 1750 to 2250)

I clocked my GPU to 1300 and mem to 2100 (Anything over than that gives me a lot of errors on hwinfo).

How are people able to get 30 mh/s yet this card is only able to get 20 mh/s?

Any help?

Thanks!

Hi @Claymore

I just decided to mine both ETH and SIA at the same time using EthDcrMiner64 v9.7 but I see a big difference in speed when mining.
On the front page you listed that I can dual mine "with no impact on Ethereum mining speed".
I have 2 R9 290x which mine at around 32mh/s on ETH (single mode). When dual mining ETH & SIA, I get around 20-23mh/s on ETH and 700 mh/s on SIA.

Am I doing something wrong?

Here's my config.txt file


And my start.bat


Both pools are accepting my shares so I know those are configured right.
Thanks!

Hi Claymore,
Because of the AMD init bug (where cards are not initiated sequentially) the current miner version (9.5) is unable to know which card is which.
After looking at HWiNFO I noticed that each card has a DeviceInstanceId which doesn't change when I reboot my machine. Why can't I use that to target a OC on that card? Right now every time my machine reboot I have to manually OC each card (Kinda annoying).

Doesn't sound like an easy implementation but it doesn't hurt to ask

@Claymore would it be possible for the miner to show more info about the GPU?
I have 3 cards running, one on PCIe slot 1, 2 and 3 (PCIe slot 0 is empty). They are all R9 290x TRI but when I start the miner, "GPU#0" is either PCIe 1 or PCIe 2. This is annoying since each card is clocked differently and I can't tell which is which. I have to use Afterburner to figure out which card is "GPU#0" (Base on the clock speed).

Also, what about a feature that allows us to "label" the GPU? Instead of the miner showing "GPU#1" I want to call it "Rack0", maybe a flag like in the config like:


This feature doesn't need to be implemented, I am more interested in a fix for the issue above

I'm running Windows 7 Home Premium
Thanks!

Thanks for the info

So I recently purchased a few risers and before fucking with anything, I wanted to confirm with you guys.

My Mobo has 4 PCIe and 2 PCI (not express).
Can I connect a PCIe riser on a PCI? If so, whats the pinout (I couldn't find anything on this).

Sorry for the noob question :S

Thanks!

For some odd reason the cards are now being detected :S



Btw, is there a way to rename or give an alias to the card? I remember some miners allowed renaming the GPU's (so that I know which is which instead of GPU#0...).

After 3 days running this miner, I ran into a few issues.

It sometimes think that GPU#0 is GPU#1 and vice-versa :S (I can deal with that) but the issue I can't seem to find a fix is this:

I have an Intel Pentium G2130 on a AsRock z77 Extreme 3 mobo. The CPU has an onboard Graphics Card. So in BIOS, I set the primary Graphics to "onboard" (aka, CPU). Everything works, MSI Afterburner can detect my GPU's and so can HWinfo, but for some reason, EthDcrMiner64 can't!


I want to enable the CPU's graphics card just to ease the load of one of the GPU's (I noticed that I get better hash rates and "Share Accepted").

Is this a bug with the miner? Or am I missing something?

In 17 hours on stock (29.5 Mh/s) I generated 426 shares.

I boosted the GPU clock to 1160 and lowered the mem from 1300 to 1250 and I'm going to compare with the stock value. It's currently hashing at 32.7 Mh/s



thanks for the help

== Update ==

16 hours later @ 32.6 Mh/s I already generated 485 shares. Not bad.

Thanks for the feedback

This is a stock card. I haven't flashed any Bios on it.
I'm going to check if HWinfo shows any error.

Also, what's the best way to test an overclock? I feel like I need to have the miner running for 3+ hours to see a difference.

Hey everyone,

It's been a while since I've done any GPU mining, but the rise in prices of certain coins really got me back into mining. Last time I mined anything was Doge coin (in 2014), so it's been a while haha.

This is my graphics card info

Sapphire R9 290X 4GB - Hynix RAM.
GPU Clock - 1040 MHz
Memory Clock - 1300 MHz

With stock settings, I get about 29.5 Mh/s, but if I bump the GPU clock on 1100, I get 32-33 Mh/s

Either way, it seems that both settings yield poor results. I'm using Claymore's Dual Ethereum miner to mine Ethereum only (https://bitcointalk.org/index.php?topic=1433925.0).

On my miner, I keep seeing "New job from xxx" but I barely see any "Share Found".

Here's a screenshot:



Here's my config:

When mining doge coin, each "job" would always be "found", but with Ethereum, I get around 4 shares found for every 10 mins.
Is this right? What do you guys think?

Awesome! I got my account back

Tell ya what...
I have BTC into this account and work into building it since I got it, about a year ago, (almost pot legendary now) so I'm the one going to take a loss here..

But I will give it back to you for free because I'm a nice sort of guy like that..

Tell me some things about the old PMs of this account by the original owner to convince me and it's yours..




Edit: OP PM sent..
