Is it possible to mine with just 2GB of system RAM?
Perhaps on Linux, windows won't like it for sure. ethminer keeps a copy of the DAG file (1.3GB currently) in system RAM for validation of nonces found by the GPU.
Guys, Sapphire Radeon R9280x toxic is at 20-22Mh/s as of writing. Im thinking of undervolting and underclocking. Seems even if the GPU runs at lowered clock, the hashrate never drops as mentioned in other threads. any suggestion on sweetspot voltage and clock speed? additional revenue on reduce power consumption. Has anyone done this?

Hi i have a couple of msi R9 380 actually doing 20.46 on dwarf each one, and they are underclocked and undervoltaged with afterburner
Hi! Also got some 380s, how do you undervoltage them? I cant change that value in afterburner.. Also wondering if you know how many watt they use?
My 380 @ 990/1500 gives 21.5 Mh/s and about 190W (3x380 rigg = 600-610W total with CPU/HDD)
Sorry i dont a killA-watt to measure it but i am guessing you dont have an msi card?, this option sometimes its blocked in afterburner for non msi, i have got the temps down to 60°C with 100mv undervoltage and 950Mhz clock, i was over 70°C

Unfortunately, the Hashrate drops to 17MHs with your suggestion. Im at 1100/1500 at 1143mv VDDC. Total consumption including mobo is at 272watts. 1 gpu only.

Temp is steady at 68 C w/o fan. I tried lower the settings and voltage but gpu crashes.

I have almost identical values: Gigabyte 280x/1100 mhz/pulling 280w from the wall (with mobo). Hash: ~21-22
I'm just getting started with mining, and would really appreciate some help!
I am running Windows 10. How much of a problem is WIndows 10?
I am running:
2x AMD Radeon R9 380 4gb cards (in crossfire mode)
I am getting about 38MH/s
Is my performance too low for these two cards? Are there command line options for ethminer I should be using? I see mention of things like -cl-local-work 256 --cl-global-work 8192.
Playing around with --cl-local-work and --cl-global-work settings I was able to increase MH/s by 10%, however it resulted in my cards running at over 90 degrees C which is dangerous from what I understand.
@benjbarker use this post just for benchmarks and not for questions. BTW, I think if you use win 7 or, better, ubuntu 14.04 you'll get something like 1.8MHS more for both gpus.
2x GTX 970 @ 41.5 MH/s with @Genoil's awesome CUDA ethminer, CUDA 7.5 on linux 17.3 with driver 352.39
sudo -s ./ethminer -G --farm-recheck 100 -F (pool eth-proxy) -U --cuda-devices 0 1 --cuda-grid-size 8192 --cuda-block-size 128 --cuda-schedule sync --cl-global-work 16384
Still trying to get the cards overclocked (voltage/power) & powermizer stuck on lvl 2 even when forced, anyone any idea how without biosflash? Please send me a pm. And if anyone has better suggestions on streamlining the hash lemme know too.
I have a R390 Shapphire and Xubuntu 15.10 and I only get 26 MH/s... Why is that? I have tried the drivers that comes with Xubuntu and also radeon-crimson-15.12-15.302-151217a-297685e but still, I am not able to reach 30 MH/s.

Could someone help me out?
O
26 MH is normal now because of DAG size. Other might know better.
Why I cant mine with GT 630 and GTX 650 ? With the GT 630 I get 240000 H/S ANd With GTX 650 I get 450000 H/S And Still I cant see mining in my pool? Why it happen? How I can fix it?

i'm using 14.5 it seems to be omega version, have 3 r9 280x getting about 67MH/s
What is performance of R9 380X ? As I can see its 18 MH/s per card? Same as R9 380 right ?

My XFX R9-390's get 28MH at stock speeds. When I OC, I get them over 30MH (But I usually don't unless price spikes).
