AMD Rebrand - RX570 / RX580 - Official Thread

[spyshagg]

RX570  solo

1090/1850 =  27 Mh/s  900mv 105watts (all card, not just gpu)

RX570 Dual

1130/1850 =  Eth 27 Mh/s + Sia 500Mh/s  980mv  150watts (all card, not just gpu)

Is this good or bad?

how?? im only get 24mh/s 130watts 1110/1900

Like the 290's and 4xx, the 5xx also  needs to mod the memory straps to get  ~3 more Mh/s


I didn't mod my 570 myself so I cannot do yours.

I have Asus Strix RX 570 Oc 4Gb. Bad graphic card

What is problem? I have Strix 470 and it's pretty lovely card, very stable and cooling is the best I saw, only no heatsink on memory... Maybe the con is Elpida memory type, but 4GB version is not using Samsung one very often...
I ordered another Strix 470 for testing with performance timings so I hope it could be even better.
Now I'm getting around 700H/s on XMR.

Hi Guys,

I've just bought 6 RX580 from Sapphire (nitro+ 8gb) and I discovered that the memory is HYNIX.
I've played around for some days to achieve a good hasrate but unfortunately the maximum I've got is 25.2 / 25.5.
I've seen a lot of video on youtube, read tons of threrad here but when I flash bios and change some value on GPU clock or Memory I can't get more.

I read for the HYNIX memory the value to change on timings is the 2:1750 to 2:2000 and actually it's the only way to get more (instead of changing 1:1750 to 1:2000).
My problem is when I try to change memory clock (standard 2000mhz) every mhz up will be result on worst hashrate.
A good compromise is underclok the GPU (1066 or 1033 mhz) and undervolt it (-100mv) while the memory is always 2000mhz and I got 25mh/s on 95w.

Any suggestions?



Thanks in advance

Hi guys! I have Sapphire RX 580 with Hynix memory (at the moment this is tested on several different cards with Hynix memory). After two weeks of reading a forums and youtube this is my results:

Low power:


Powerfull:

Try 1625Mhz or even 1500MHz, but it couldn't work at all, try it on 1 card and only for 2000MHz. You could try some performance optimized timings, but they are hard to find. Best is UberMix but this one is only for Samsung.

Help! Hey Guys... A bit of a noob here, so greatly appreciate any help.

Setting up my 2nd and 3rd rig and decided to go with the RX580... Ended up with XFX RX580 8GB GTS Black Edition

Info on card:
http://xfxforce.com/en-us/products/amd-radeon-rx-500-series/rx-580-gts-8gb-dd-rx-580p8dbd6

I was only getting 18-19 hash rate out of the box... I can't get it past 20! From what I've read the 580's should be in the high 20's at least.

This was the best I could do... In ethOS I've updated the config...
Core: I've maxed out (according to specs) at 1425.
Memory: 2220

Is there anything else I should try?? Hoping to not have to return 10 GPUs...

You're supposed to underclock the GPU and tweak the memory timings with BIOS edits.

I picked up one of those XFX RX 580s as well, but it has two different types of memory.  4GB of type 1 Samsung and 4GB of type 2 Hynix (I posted a pic from the bios editor below).
https://m.imgur.com/gallery/y74j1

So far I haven't tried to use the same straps across both types of memory...I have tried copying the 1500 from type 1 (Samsung) to only type 1, and the 1500 of type 2 to only the 2 (Hynix).  I reflashed the BIOS for 1625 as well, but it was still unstable.  I did several attempts with the 1625 Straps where I underclocked the GPU in Wattman but it didn't seem to help.

Does anyone think I should try to use the same timings "straps" for both the Samsung and Hynix?  It seems really odd/tricky to me to have 2 different types of memory to overclock independently.

As of now I have Samsung, Hynix and Elpida memory cards but never ever thought about using same straps for different memory straps.

It is even easy to soft brick your card when you flash it with right straps but something goes south during the mod bios flashing.

I would not try what you are thinking but would love to listen about the results if you do

Uh... 1625Mhz, on THAT Hynix (the shit kind rated for 2000 actual and ending in MJR) is not gonna work well. 1500Mhz timings are gonna suck worse.

Well yeah...
you could find good timings in here:
http://www.overclock.net/t/1604567/polaris-bios-editing-rx5xx-rx4xx
Maybe this? I will try this one later.
https://forum.bits.media/index.php?/topic/38510-ethtaimingirx470480570580-optimizirovannye-taimingi/

Also I don't have any Hynix, only Elpida and Samsung so I can't really say...

You have to know what memory brands you have. Use gpu-z. In bios you have 2 type but it use only one. Upload your original bios and upload screenshot of gpu-z.

I'll post the BIOS tomorrow night (my backups are offline on a flash drive and I'm not going to be back there until tomorrow).

(GPUZ says Hynix)

BIOS editor has a drop down menu where the different types are listed.
https://i.imgur.com/PDL37x2.jpg
VRAM = K4G80325FB

EDIT:
Default BIOS for the
XFX RX 580 Black Edition GTR
https://drive.google.com/open?id=0B2PQuvc5cpEaRmtDRTBmb2xSbms

The timings list both Samsung and Hynix memory.  GPUZ​ only lists Hynix, so maybe I can just ignore all of the type 1: straps?

Gets 27mh/s light OC without bios modding.

Hello people, i bought an rx 580 (msi gaming x 4gb) and it turned out to be an elipda ram, Polaris is not reading the timings at all, anyone faced this problem and could solve it?

yeah i downloaded this one, saved the bios with atiflash 2.74 and still the tab of memory timings is empty

FINALLY!

For people who are looking for a stable BIOS I found it here:

http://1stminingrig.com/best-bios-rom-sapphire-nitro-rx-580-8gb-oc-hynix-memory-30-mhs/

GREAT Bios, from my 1st test I got 30mh/s STABLE both version (1 & 2).

Thanks to everyone for help.

112W are too high for 30mh. You can optimize it more.

112W are too high for 30mh. You can optimize it more.

even with free energy?

Yep, lot of extra heat.

[spelunker]

Does anyone know how I can get Gigabyte Radeon RX580 Aorus (Samsung memory) to hash at 28+
Mine was going at 24MH/s on EthOS, I flashed it in Windows and now my 6 cards only go at 17MH/s per card.

Is it possible and how?
Thank you!

[Lordpschorr]

any suggestions to take it down?
actually I've undervolt the GPU, overclock memory and set the fan to 40% for a stable 30mhs and 53°.
At the moment I'm testing it with only 1 rx580 on test machine.
