I can confirm a ~2% increase for Tahiti cards... Thanks Claymore

what is gmap option???

[crazyq]

One of card after hour just increase fans on full and crash rest of miner ( reset doesnt work so need to turn off all miner ) anyone can tell me what can be wrong?

[markus124]

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".

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

[kisk]

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

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.

Is Equihash memory or GPU heavy on your GPU?

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

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.

[thesaltonsea]

In all rigs does not recognize 1 gpu
problem with rx 480 4gb

have same problem, with 3 or more rx480 cant mine, if i remove 4th its ok and its mining without crashing , tried diferent risers and os and drivers but still same , and it just on one of the rigs

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

[snakey]

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.

[Havane]

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 still have stability issues with my Sapphire 280x Toxic cards, no matter intensity or clocks.

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

I have similar problems.
