AMD Rebrand - RX570 / RX580 - Official Thread

[dragonmike]

The question is: does undervolting/clocking your core (and the resulting lower temps) allow you to clock your memory higher? I think it's really hard to gauge what effect the one does on the other.

Can anyone help me. How are people using claymore commands to set clocks and volts. Even on claymores page it says ati blocks this now. Yet on one of my rigs claymore commands work. On an identical rig they crash it. Claymore commands crash every rig i've ever had when trying to set clocks and volts. Even if its just settings stock clocks. Yes afterburner works just fine pushing the cards hard. But i can't undervolt more than -100mv with afterburner. How else can i undervolt more?

[mettalmag]

I myself will try gigabyte 570 4g gaming, but what if one has a free el. what will be best 5xx series?

[Junkey]

Junkey, could you share the strap? That's a high rate and clock for elpida

Nothing custom.  Just the 1500 strap copied up.

Just flash them with a lower voltage !

Not that easy - AMDGPU ignores PowerPlay changes (DPM state mods), and there's no init regulator section in VoltageObjectInfo to add an offset. You gotta get creative.

Finally was able to do it though bios, takes offset just like IR3567B, just different register values, and some weird read write bit stuff as seen in http://www.overclock.net/t/1621800/would-appreciate-help-in-finding-editing-the-voltage-offset-in-the-rx480-bios/100 . Otherwise works like a charm! VDDCI seems to work too!

I have tried to overclock my RX580 Sapphire Nitro+ 8GB with Hynix memory, but I got less mh/s then before.
I dont understand this. I tried to oc with stock bios (hashrate dropped from 22.5 to 15 mh/s) and with modded bios (dropped from 27-28 to 20 mh/s). Why?
I tried oc with MSI Afterburner, Trixx and Wattman, but always the same... On my RX480 overclocking worked, I dont understand.
Pls help.

Can anyone use rx 480/580 mixed?

Try rebooting after setting a new clock. I have to do this on memclock for some reason.

[pzycho010]

Quick question, does brand matter when choosing an RX570 card?
Saw sapphire, gigabyte and msi rx570s

[joaocha]

Msi Afterburn did not overclock memory on 5xx,
You have to use Trixx to make everything runs right !

RX580 Sapphire Nitro+ 8GB Hynix at 1150 Mhz Core and 2150 Memory and Voltage -75mv - Trixx
RX580 Sapphire Pulse 8GB Hynix at 1150 Mhz Core and 2150 Memory and Voltage -75mv - Trixx

Maybe not all cards can be undervolted -75mv OR maybe more then -75mv

Long time i tried bios mods and many other memory straps, this one is the only working flawless with 30 MHs.
Other straps got me lower MH on memory overclock or blackscreens and artefacts

Are u sure this times are for the RX580 Sapphire Pulse? Because my card has the strap with 0:xxxx?
Can u please confirm?
Thanks

[articlemore]

Guys, Can someone suggest me which card I should get for the 570s(All Rx570 and all 4Gb): Sapphire Pulse ITX 4Gb, Asus ROG Strix OC 4gb, Gigabyte gaming 4Gb, MSI Gaming X 4Gb, Sapphire pulse 4Gb, Gigabyte AORUS 4Gb, Sapphire Nitro+ 4Gb     < ----- They're listed from Cheapest to the most expensive near me

Thanks,

Thanks,

Just get whatever is the cheapest with 2+ fans. Vega is to be released soon and the prices will probably go down a bit anyways. All the cards above all hash around the same after mods.

[articlemore]

The ITX is the cheapest here, and people are saying that even with only 1 fan they stay cooler than other 2+ fan one, and that with modded bios they can go up to 30,5Mhs. But I don't find anywhere that people that about the ITX one...so where to find the ressources to mod the bios and oc?

[articlemore]

And another questions: for Dualmining wich one would you guys recommend? Decred, SiaCoins LBRY or PascalCoins? for the 570s

[Marvell1]

whats straps are ppl using for the XFX elphida and the Saphire Pulse ? I cant get those things to do anything with 1625 or 1500 straps

also what mem clock is recomended ?  Thanks

If you have Sapphire Pulse RX580 8Gb with Hynix Memory yes
