Amazing how every update boosts my hashrate a lot!

Version 4.0 Inefficient with multi-card rigs??

My hashrate drops as I turn on more cards, anyone else experiencing this issue?

most of my rigs are:

6x R9 390's
Win 8.1
15.12 drivers
CPU = G3260 Haswell Pentium

I think the issue might be the CPU, only 2 core and does not have AVX

With just 1 or 2 cards running I average around 90-95H/s per card
with 3 cards on... 80-85H/s per card
with 4 cards on... 75-80H/s per card
with 6 cards on... 55-60H/s per card

Otherwise, everything is pretty stable, been mining ETH for months

Try -i 0
90-103 sols per each 390 in 6gpu rig with Celeron g1840

Putting in my two cents.

XFX RX480 8GB x6(stock) - crashes at "-i 2." Currently testing default settings to see if rig crashes again. *EDIT* Rig crashes on stock settings and default intensity. I would also like to add that at 4 GPUs the rig was stable, I just added two more cards tonight, and now I'm experiencing the crashing. Any ideas?  I have PCI set to Gen 2, is Gen 1 necessary?  This rig has a cheapo dual core cpu, 4gb of ram and h81 btc mobo.

MSI RX480 8gb x4(Memory clock 2200, Core clock stock) - Runs fine, no crashes. "-i 2" setting.

you can open task manager to see what the cpu is doing. my cpu is also 2core and i'm on 88% -i 2
If the cpu runs @ 100% on -i 2 its not pretty good  it will be better to try -i 0 or -i1

I use win 8.1 with wattsman and mod. Bios with atiwinflash and polaris. 1303 mhz gpu clock and 1950mhz mem. 50% powlimit getting 80 - 86H/s each card rx480 4gb devfee on

[gennadiv]

during the operation of the program until a failure is not found - but the fall speed was very considerably - while at the moment here
ZEC - Total Speed: 130.837 H/s, Total Shares: 3047, Rejected: 4, Time: 10:13
ZEC: GPU0 43.328 H/s, GPU1 44.763 H/s, H GPU2 42.745/s

[Tuner77]

All hail Claymore. 85sol nitro+ 480, 80sol xfx gtr 480

Anyone else notice 40% cpu usage from the miner?

I'm using -i 2, only two cards right now.

Getting this error all the time on different pools. What is it ?

server: bind failed with error: 10048 (port is busy, use different -mport value), next attempt in 10sec...

help pls

that was from a similar thread, you may find answers there..good luck

thanks!

[buckrogers]

What does 'DevFee: Stop mining and disconnect" mean? I just run stock everything with 2 x 290. Am I not paying devfee? I want to!

I believe that is part of the code telling you the dev fee portion of mining has finished for the hour

please support the dev fee

Keep up the great work @Claymore! It is very big of you to even include the option to disable that...if people do, ? i just have no words.

thanks!

Can you help me to confirm MSI RX470 4GB speed with Claymore 4.0, -i 2, @ 1050/1900. Thanks

[Sam123]

I have 4 RX480 the first 3 cards are running ~60 H/s but the last one ~18 H/s.
I switch the cards and it's always GPU3 (last one) that has the lowest. Why?
I tried -i 0 or -i 2 does not change
Thanks

[snakey]

Anyone getting good results with Sapphire rx470 8gb?

only getting around 60 - 64.

A little help please?

Good video to learn how to set your timings hope its helping

Thanks, seen this video but its for the 4gb version....

IS it ok to use on the 8gb version?

probabaly the usb riser issue . otherwise I have seen this. Just reboot the system and the card acts normal.

147 x RX480 a 70 SOLs = 10290 SOLs
31KW @ 20 Cent/KWh

thats means round about 10.ooo Dollar p.M. income ^^

and I still complain that 0.05 Cent/KWh expensive.

what are you working with?
Hardware, mobo, ram cpu etc?

i may be able to  help with some experience.

thanks!

@ Claymore please do something in your miner for Sapphire Nitro RX 480 8GB OC aswell for getting 100h/s on stock, like you done for r9 390x 

Happy mining, you are a champ

Hello.

The R9 390 have 44 unit computer.
The 390x have 44 unit computer.
And RX 480 only have 36 unit computer but this GPU is more efficient energy than 390 and 390x.

I think that RX 490 will be the best GPU for mining and we will see in 2017.

Best regards.

What happened? Before all of you were unhappy that he took a big fee, but now when he said that he might stop supdating the miner or sell them all you started to act nice.

This is the most faster miner at the moment and all of us have to accept the fee. 2.5 is nothing I am not big miner and is 20-30$ per month for me and I never had problem with that. If the miner was trash ok, but isnt so happy minning brothers!
