I used RX 480 and got only 24MB/s rate

[thespycry]

I have a Sapphire RX 480 8GB Nitro + OC which runs at 1342 MHz (boost speed)
I copied the bios and edited the memory straps 1750 -> 2000.
With that I am getting about 28.1 MH/s (instead of 24)
The thing is, if I increase the memory speed to 2250 Mhz (or lower the core as well), that has no effect and the speed stays  at 28 MH/s.
really weird.. This happens on all of the cards I own..

Any ideas ?

I am sure you have samsung memory cards.
There is this guy who runs memory at 2080 and core at 1125 or 1150 with 910mV and gets 29.3+ on these cards you have.
You need to find optimal settings. It's not just one or two parameters.

And ofcourse his mod is good for eth only, crashes bSod on dual if you try to increase memory a bit more.

dude there is many post on this
to know your memory use gpu-z end check if you have hynix elpidia or samsung ram that's all after you take the rom for your memory

I have samsung memory on mine



can you please help me with flashing bios, never done this before, some good tutorial?

tnx

get polaris bios editor, take your original rom with ati flash, save it.
Open it with polaris and strap the timing memory 1725 to 2000Mhz  (you copy the value of the 1725 timing ram on each line to 2000mhz sry for my english ^^ ) and flash your card with the new bios

Remember to back up the original BIOS before than flashing anything!
You can find some BIOS online, but it's still better to have a copy of your own

Flashing an RX 480 with custom bios on dual mining ETH PASC improve hashrate ?

[Qazo]

awesome, only replaced 2000 straps with 1750, i'm getting 2-3 mh/s  more per card when dual mining DCR, temperatures also much better

settings:
5x480 nitro OC+
core 1100  , 1000mv
memory 2100, 1000mv
-dcri 35

eth - 135 mhs / dcr-4700 mhs

980w from wall - this is little bit to much because i have Corsair RM1000x

which settings should I change to get lower energy consumption from wall?

You got to update the bios

Dowload polaris editor and atiwinflash

Then make sure you know how to switch to silent bios and via versa in your card.

Back up BOTH of your bios.

Then reply to this thread for your next lesson.
