done a try to OC a bit now. from 1080 core til 1150 core volt +25 and power limit +50
did go from 28.4 to 30.3Mhs
temps are around 70-72c with fans on auto around 45%

that didnt go so well for me

computer hung after 20min
will give a bit lower oc and see if that works

Try 1100, -100mV to core & aux + tap user defined fan profile. Leave power limit as it is.

-100mV to core & aux set.
but i see some black lines on the screen when i have 1100 like the graphics tear. get lower temps 64c now at 1080
didnt see much diffrence when i had it at 1100

-100 gave me black screen after a few mins.

What brand is that card? And what PSU?

Sapphire R9 390X Nitro 8GB
Corsair TX750

Ok I thought it was 390. Reset everything.

Do you have GPUZ installed? If so does it show memory controller load under sensors tab? What is it? What drivers are you using? And what OS?

memory contoller 70-72%
Windows 7
Non-WHQL-64Bit-Radeon-Software-Crimson-16.2-Win10-Win8.1-Win7-Feb23

Ok. Is it too much asked to wipe out drivers with ddu and install 15.7.1 drivers?

nah i can give it a try for sure.
what do you want me to try after?

It depends on your particular cards. Some of my cards works well on 1160 MHz at -100mV, -100mV. Some works at 1100.

That's what I thought too after playing with nvidias. In fact I was running these amd's long time at 1600-1700 mem thinking it automatically gives me more hash.

Nvidia with 256-bit memory lane and 3,5-4GB is memory limited, amd with 384-bit and 3GB suffers from DAG-file size, amd with 512-bit and 8GB is begging for core overclock.

maxwell cores are typically overclocked/boosted from the factory so there may not be as much room left anyway compared to AMD's, but power to get there is still the differentiator.

I don't see 390's with less than 8GB, or less than $300+ each... but at $12+/ETH, ROI is so short for anything these days. Shocked

Cheap 290 with 512-bit bus and 4GB does closer to 30MH. It just doesn't show me that memory controller load...
