- Linux :Ubuntu 16.04.03
- Driver: amdgpu-pro-16.60-379184
- Overclock with ROC-smi and edit memory clock with : echo “15” > /sys/class/drm/card0/device/pp_mclk_od
- Core clock : 1314 Mhz – Memory Clock : 2012 Mhz
Can you share your memory brand ?
And your bios ?
Thanks
Memory Elpida.

Same request … Memory brand and bios
what’s the power usage with this high hashrate?
How do you get the Core clock : 1314 Mhz – Memory Clock : 2012 Mhz when using ROC-smi?
I just get :
5 41.0c 19.255W 1071Mhz 1725Mhz 20.78% auto 0%
Having hard time finding the same driver. New driver do not work at all.
Did U find working driver on win 10?? New one do not work and I can’t flash back bios without working drivers. Please help guys
New autodetect driver work on Win 10
Autodetect?? What U mind??any link??
Maybe I explain my problem. I flash bios (this one from roelspace)and after that my win 10 don’t recognise a card. I did everything thinking what u said before and still doesn’t work. Maybe my bios is wrong I don’t really know now :(any ideas or I lost my cart forever??
download The pixelpatcher utility atikmdag-patcher.exe to patch the driver running to recognize your patched cards.
Or just disable the card in device manager to use atiflash utility on the device directly, it will work to flash BIOS anyway.
Pixel patcher shows failed to locate driver???
to overdrive core clock type:
> rocm-smi –setoverdrive 15
to overdrive memory clock type
> sudo echo “15” > /sys/class/drm/card0/device/pp_mclk_od
Hmm, did not work on first attempt. I’ll have to test some more.
–setoverdrive #: This sets the percentage above maximum for the max Performance Level. For example, –setoverdrive 20 will increase the top sclk level by 20%. If the maximum sclk level is 1000MHz, then –setoverdrive 20 will increase the maximum sclk to 1200MHz
If you want to avoid installing ROCm (to use rocm-smi), you can both set & verify both your GPU & mem clock speeds (sclk/mclk) with:
Set:
sudo echo 15 > /sys/class/drm/card0/device/pp_mclk_od
sudo echo 5 > /sys/class/drm/card0/device/pp_dpm_sclk
And monitor your clock speeds with:
watch -n 1 cat /sys/class/drm/card0/device/pp_mclk_od
watch -n 1 cat /sys/class/drm/card0/device/pp_dpm_sclk
This will refresh every second.
@roelspace- have you been able to find any newer drivers to use than 16.60? FYI, mine is the Lexa “20” RX 550 (Asus Elpida) and about the best I can pull is ~460
@BSuperfly I have test amdgpu-pro-17.40.2712-510357 working on Ubuntu 16.04
I have 3 RX 550 all Elpida memory , HIS, Saphire and Powercolor. Only Saphire can surpass 500, HIS 480 and Powercolor 460 maximum.
Did you just mean you overclocked both the core and mem with the rocm-smi command？And we can avoid all the saving the stock vbios, editing it, and flushing it back with various tools or bios editors?
Editing and flushing back vbios are the parts which I hate and dread the most in mining because it’s exhaustively tedious and dangerous. I don’t want to brick my cards.
Please reply.

Thanks I will try it later. Hopefully will work
It’s sapphire pulse radeon?
Hello,
How can I verify the memory brand of my ASUS Rx 550 gpus?.
Best regards.

I can’t overclock. The value in pp_mclk_od don’t change:
# echo “15” > /sys/class/drm/card1/device/pp_mclk_od
# cat /sys/class/drm/card1/device/pp_mclk_od
0
# cat /sys/class/drm/card1/device/pp_dpm_mclk
0: 300Mhz
1: 1000Mhz
2: 1750Mhz *
What amd driver do you use?
18.20. But, I think that is for this Rx550 card. I tested a rx460 and I can overclock.
