Claymore,

I have 42 Radeon 7970's. I've been mining with your miners for a year. I get 1.17KHs with 12.0 on a 4 card rig but every version after that lowers my hashrate. I just tried 12.4 and same problem. All cards hash slower. Getting 1.05 max.

Any suggestions? I have increased the voltage but that doesn't seem to do it.

Thanks.

Have you installed newer drivers? I get less h/s with those 17.x.x drivers than with 16.9.2

You can try also the -asm option, to use the same algo than the v11

-asm 0 will use v11? So same power as before...

Will give it a go.

Thanks.

I unplugged 1 card and now 5 have been mining without a stop for about an hour....Normally restarts after 5 minutes..

I will leave on till tomorrow and see if its ok...

Looks like the new claymore version is asking for more juice from my psu, looks like I need to get 1200w now.

My 4 GPU RX480 rig has been mining stable with all 12.x versions of Claymore. When I attempt to add 5th RX480, miner hangs after awhile with OpenCL error. Miner also doesn't recover, and keep mining; entire system hangs. My mobo is MSI z170A. I have modified BIOS to mine with more than 4 GPUs per guides in forums (change pcie to gen 1, enable 4G).

So frustrating trying to figure out how to get 5th miner to run stable. Have tried with -i 6, -i 5, now trying with -i 7....

Also, not all 5 RX480s mine at 300 H/s. One is 300 H/s second one real close, but other ones like 250-270 H/s Undecided

Have you got the same problem with ETH solo mining ?

My rig hang after few hours with 6 RX 480 : maybe it's my PSU, 1020W from the wall with a 1000w EVGA PSU (can archive 1200w from the wall), but I have no problem with claymore eth miner

Claymore please help.

I have been running a 6 gpu rig (470s) on a 1000w psu with the older claymore versions with no problem but since these new v12s have come out I keep getting reboots every 5 minutes or so....Has your new version of the miner added more power per gpu? That is the only thing I can think of for the reboots.

Any help from anyone would be much appreciated.

Unplugged 1 gpu, will see how that goes.

Is Equihash memory or GPU heavy on your GPU?

No change in my modded RX 480 4GBs and 8GBs, or R7 370s -- sol/s, temps, or power draw.

how are temperatures and power draws? i'm guessing pretty similar.

what is gmap option???

-gmap sets GPU order in fan/temperature list. This option is similar to "-di" option, but it manages fan/temperature list.
For example, if you have two cards, you can change their order by adding "-gmap 10". Another example, reverse order for six cards: "-gmap 543210".
This option is also useful if you want to exclude some GPUs from the list. For example, if you have four cards, you can exclude first GPU from fan/temperature list with "-gmap 123".

My MSI R9 390s went from ~405 H/s to ~415H/s
MSI R9 390X no noticable increase.
Sapphire R9 390 slight increase, hard to measure

Will report in 24h!
