that card should go fine with Mem 2150, rest of your values are okay. U have aggrresive under volting enabled, right? I have had that same blue nitro and i belive i have 1 or 2 580’s with that same Mem. did u download the new vbios file for the gpu from tech power out site and patch that with polar? defo you should be able to go higher Mem… there is something wrong… with bios i quess… cant know for sure naturally 
i will try the bios from tech power out site later , i had enabled aggrresive under volting
should i use 8+6pin? or just single 8pin
Hi there, Most motherboard have one full speed x16 slot (long slot), if they have a second one it usually runs at a slower speed.
Looking at your motherboard manual the first slot is a true x16 slot running at full x16 speed, your second 16x slot runs at a max of x4 so will be approx quarter of the speed of the first card unfortunately.
You can get motherboards with multiple true x16 full speed slots but I think they are quite expensive - its cheaper just to upgrade to 8gb cards.
I would suggest you just run one 4gb card in the full speed x16 slot and sell the second 4gb , replace with a 8gb which will run at full speed.
im using phoenix miner, the team red miner was work 22mhz
already tried the bios from tech power
same error i getting… GPU 0: detected DEAD (06:00.0), will execute restart script watchdog.s
power up with 8+6. If your oc is low and your getting gpu dead…it must be bad riser/usb/pcie connector or faulty bios. If u havent yet, change riser from working card and put this ones riser to that one.
New vbios and still… I had dead gpu errors on several gpus with team red miner a while ago, i rolled back (from flight heet) to TRM 0.8.0, that worked at that time, now latest TRM is better for me, so im on that one. strange…hope the whole gpu is not paperweight 
At one point i applied TRM conf options to get all running, like–
–init_style=1/2/3 Specified the init style (1 is default):
1: One gpu at the time, complete all before mining.
2: Three gpus at the time, complete all before mining.
3: All gpus in parallel, start mining immediately.
–watchdog_disabled
Forces the watchdog to not execute.
I actually runned my rigs without wachdog for a week or so, as long i found my source of issues at the time.
I know people are running 580´s with high clock´s, i usually dont go ove mem2150/vdd850/core1190.
That seems to be max for stable 24/7 365 - if ambient temp is on the cool side, if warmer, like now on daytime…gpus starts to spit invalids when high oc and gpu mem/core temp gets higher. Nights are okay to go with “max” clocks, but daytime its good for my setup to come down with clocks…rather lower hash than loads of invalids imho
Hope u manage to solve this.
thanks bro , my problem already solved , i think is the BPE 1click mod doesn’t whit my 580…
i just found a bios from here : Прошивка bios AMD - #2195 by BiosEditor
yea they not speak english , lucky chrome has translator XD
and i able to get my mem over 2040
now i runing at 2200 mem with 33.20mh (still testing the stability , i increase 10 mem every 30min)
anyways really thanks for your help !

Was able to use PBE to do the one click mod for this Asus Expedition 570 8GB. However, after putting it back into the Hive rig, it was painfully clear that it could not OC as high as the ROG Strix. Going beyond 2050 memclock crashes it, while anything above 2030 reduces hashrate. Hence this is the result:
Note that the cards below GPU2 are ROG’s.
Can anyone help? I got normal RX 480 8 GB OC core:1150 and mem: 2200, but ETH hashrate only 26 MH/s.
(5) Asus Rog Strix RX570 this what I have running …very stable (Polaris “one click” bios mod)
The (1) with Samsung memory is a tough one to get right… 
Try the settings I have above (scroll up). I have the same card.
can i ask for your sapphire rx 480 bios? is it the nitro + one or the pulse
mine wont reach above 26 mh/s
I have the Nitro+. Have you tried the settings that I have? You will also need to do AMD memtweak.
yea i did… what it does is making me get GPU 1 detected dead :c
Hi bro can you send me the oc sitting and your bios for the rx580 Asus mem Samsung because I only got 28 MHz and try Polaris but not work
This stable for RX580 or RX570, man? thanks!
Hi! Can you share the OC of the PowerColor with hynix memo, please?
Hi
I use different oc´s based on what pool im using, ambient temp etc… currently im on Ezil pool and their servers are really picky about over tuned gpu´s so im config A @ 2140/1/845/1/1170, that gives shy 32mh without invalids with Ezil - ETH&ZIL.
I usually dont go above 32.5mh, that only creates issues with my gpus and allso i try to keep wattage low.
Currently investigating possibility to lower wattage with Red bios editor, but that is really time consuming and takes rig down every now and then for several hours…bricked cards etc.
These OC´s are allmost like “default” with modded 580´s
