25.5MH/s

Hi all. I have gigabyte gaming rx580 8gb cards and am only getting 25.5MH/s even after changing the timings at 2000 and 2250 and over clocking men to 2125. Any ideas?
Comments
I took the straps from this BIOS: http://1stminingrig.com/best-bios-rom-for-sapphire-pulse-rx-580-8gb-oc-hynix-memory-30-mhs/
mvvdc at 950
Stable between 55 and 65 degrees with fans on auto. (depending on the card)
running the same straps as you.
All my hynix cards are pulling between 29.1 and 29.6
(slowly dropping with DAG but this is as of today.)
....
I think you should up your clock to 1200
Also depends on a card manufacturer. I'm not able to overclock Hynix on my PowerColor RX580/8GB-OC over 2100 to be stable, but can do 2250+ with the same Hynix chips on the Sapphire RX580 Pulse 8GB
Proof? I bought 5 Sapphire RX470 4GB cards and they all came with Hynix memory. So, they're "identical", right? Visually, definitely. But ASIC % differs across all of them. One clocks as high as 2160mhz on the memory with minimal MEs. One can't get past 1920mhz without MEs exponentially increasing until the drivers crash.
I was able to get my hynix cards to 30.x using GPU at 1350 and memory at 2200.
CVVDC is 1050
MVDDC is 950
Temperatures are between 58 and 68.
roughly 110w draw per card (as per afterburner)
If you want to reduce electricity consumption, I used the below settings to get to 29.x
GPU at 1200 and memory at 2200.
CVVDC is 850
MVDDC is 950
Temperatures between 50 and 62
Roughly 95w per card.
6600k I5
32GB DDR4 3200mhz
850W Corsair 80Bronze PSU
512GB SSD
ASUS STRIX RX480 930mv/1100mhz core clock/2000 mem clock
Total overkill on the ram, case fans, and GPU voltage, but it is a work/gaming machine. Assuming everything minus the GPU pulls 50W, the GPU is pulling [email protected]/s (TOTAL watts, not just the core). The GPU core according to HWInfo64 is pulling 75-76W. I'm sure users who aren't gaming could get 28-29MH/s out of the exact same card with no stability issues (on a standalone rig), making the power draw decrease even more significant in terms of overall efficiency.
Until the end of August, my electricity is free. (renting an apartment with all utilities included.)
I'm trying to milk it as hard as possible. The only reason I'm reducing voltage is to keep temps down.
even then, for preparing for Sep, I've had my cards running at:
850mv/1200mhz core clock/2100 mem clock
i think that pulled like 29.1 or something. (likely 28.8 after recent dag drop)
Can someone please share his settings for AMD Wattman to increase the hashrate? I get only 21.5 Mh/s with ETH. and consumes real 175W on the wall riser included (in GPU-z shows 120W, not real).
I do not intend to flash / mod the bios. Only from wattman settings, MSI Afterburner, or Claymore config file. I have 3 cards and they have the same hashrate.
+Question: Overclocked, how many watts would consume? Would be safe 24h/24 OC and not modded in bios?
Thank you.
drop the core clock and tank the voltage too.
