dude, i CANT see my temp... lets focus on that part.  Kiss
bro i got your Issue on my Sapphire
raise your fan speed to 90 % at the claymore config add -tt -90 like that

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

EthDcrMiner64.exe -epool eth-eu1.nanopool.org:9999 -ewal 0x5404a56d1b6bd124196a2c17028eeaaf3c9be0ba/worker1/ -epsw x -tt -90

and tell me the difference

My fan's dont respond to the -tt -90 code. No idea what is going on. As long as my room is cooled, the xfx's will run 29 mhash. But when it gets hot they will (throttle?) run 25-27mhash.

I also have the issue with my sapphire's. I tried to mod the rom, went wrong, flashed the original bios rom back, cards are running smoothly 27mhash 80 watt but i cant see temp or clock's. HOW?  Huh

27mhash 80 watt Huh

which original BIOS is that?

Can share?

I finally used my daily Win10 box to flash my MSI RX 480's (8GB) with the 480LowEnergyOK.rom file. Flashed and put back into my Ubunut 16.04 mining rig. Getting steady 28.5MH/s (171MH/s rig) and the entire rig + box fan is 995w at the wall. 4-5MH/s slower than my R9 390 (8GB) rigs but 1/2 the power. Sapphire Nitro+ RX 480's on the way, but 4GB type this time.

Smiley Super happy.

Nice rigs. Congratulation for the successful mod. The watt consumption is quite impressive.

I wish I had dabbled some time on Linux - this approach above is much cleaner - any tutorials on Claymore Dual Miner on Linux anyone?

Oh Scheizen! So that is just you tweaking the wattman settings and not running a custom ROM?

i got 27.3 mhs avg with Eliovp rom for linux.
i realize that the speed is going up and down from 25 to 28mhz.
mostly on 28.
maybe thats why the avg speed is around 27mhs.
anyone got the same result?

is 30mhs is achiveable?


tks,

Finally found some time to play around some more.

At this moment i'm around 31Mh while the gpu alone is consuming around 85watt (gpu-z), also measured ATW and got 0.59A, so here that's around 130watt.

Eliovp.

You going to put out a new Win 7 guide on how to do ROMS? I have tried 5 or 6 times now and each time it f*cks up.

It may be my GPUs or Mobo tho. I kept having issues with gpu 1, and last night I switched gpu 1 and gpu 0 around for their PCI slots and now when I turn off AMD Crossfire I get a blank screen.

How to flash roms? Or how to mod roms?

Sounds like a driver issue to me..

I assume this doesn't occur when running on a stock rom?

When I run the custom roms after flashing my cards, I get Code 43 and Code 10s on the GPU 1 slot. The GPU 0 slot says that it is working properly.

Running driver 16.8.3  on win 7 pro.

Even after signing the file and putting into my windows driver folder, AMD still says there are no graphics card installed.



Once I flash everything back to stock bios, and replace the file in my windows folder it works like a charm.

you need to also put your PC environment, CPU, mobo, etc

see if it throttles down like the previous lowenergy rom.... i am suspecting temps to be the culprit...

you got to list down a checklist for the device signing thing because many members have some issues and cannot use the rom.

I measured ATW, 0.58A, so 130watt.

Did you see the temp? not going over 60 degrees mate Smiley

It's stable as a rock Wink
