Hi , I have modded my rx470 Samsung using uber mix , very very pleased with the results , works great.

I presume I cannot use the Ubermix 3.1 Samsung memory settings on my Hynix rx470.....I know I can simply just cut and paste from 1500 upwards , but I am told that is not the best way .

So does anyone have a link to the Hynix memory performance settings so I can cut and paste it into my bios using Polaris editor.

TYI

Aaaaah thank you , I am guessing , I would copy the part in bold to all the above memory sections in Polaris editor ?

Yes, bold one for hynix. I'm using it with my RX470 Nitros non plus.

Fantastic thank you , In the short term I just cut and pasted the 1500 to all the above .

What are your settings on afterburner and what are you getting Mhz etc ?

Yes, just paste that bold hynix strap from Eliovp's post in yours 1625, 1750 and 2000.

Mining Music now, but it's the same for ETH.

Nice you got your 4 cards running nicely :)

Main issue I have , is that all my miners are at my office that I rent , free electric as it is included as part of my rent......excellent during the day 8am to 7pm full Air con , but after 7pm to 7.59am  no aircon , it gets very very hot in here with all my rigs running, so I tend to not over push my cards as they will work great during the day , but once the heat starts to build after the air con is switched off , the cards can crash , so anything around 26-27 mhz is great by me :)

Hey , just spotted your core voltage is like - 96 , the lowest my cards will goto is -36 , how do you make it goto -96 !?!? is it another polaris editor tweak ?

If you have only this card you can try following this video, it is for modifying Samsung BIOS memory of RX 470 normal version but should work in mining edition too, it's the same card after all.

If you have more than 10 cards its best to buy a specific bios mod file from Ebay for 15-20 Euro as it is worth it, but only if you have more than 10 cards available.

Anyway that video should help you quite a lot. Wish you luck in improving your card performance.

Don't spend money on a bios, very easy to do yourself.

I use the uber mix on my rx470 Samsung, it does 28 to 30 now.

Just follow the instructions and don't forget to use pixel patcher once you have modded your card, or the drivers will not work correctly.... Also back up your original bios, I could do a basic mod on a card in under 5 minutes theses days...

thanks for reply

but i can't figure out, can i use performance straps "RX580/480 Performance Timings" for 470 ?

Hi, that is what I did, I copied to 1625 and above, also use msi afterburner to oc the settings too.

my mod is 1750 to 2000 but i'm gettinig 26 mh so i want more speed maybe uber straps helps me :)

Got my Sapphire RX470 4G mining edition today. Tried to modify its BIOS, but the saved file under Polaris Bios editor doesn't show the correct MHz value for memory. What to do?

Download different Polaris Bios Editor. I think you need version 1.5. search for it, you will find on github.

OMG! :-) Thank you! So simple.

The easiest way is to use SRB Polaris. I've recently updated my guide with this editor.

BTW that timing strap from Eliovp is for Elpida... it might work with Hynix, but I'm pretty sure he made it from Elpida strap.

Excellent work mate!

I have hynix one model.

What is your opinion, what is the maximum ETH hashrate with solid power consumption/solid temperature for a Sapphire RX470 4GB Hynix?

I can do max around 30MH/s, but Wolf0 might do it a lot better like 31-32MH/s maybe... or Eliovp.
