The limit is set by the nature. You can be lucky, if the 1500MHz RAM works @1950MHz.
But maybe I misunderstood your question   

Hi
But why it's so? Such cards have another hw components?
I've tried to change limit in bios and also have tried special option in AB. The both does not work.
Do you know where the 1950 limit is set? At bios level? At win drivers level?

Thanks

PS. I have sapp 11267-18-20G

Bump!  Anyone?! If not let me know I'm cool either way.

560 is no good for mining how every 580's are expensive but if u get 8gb one u can duel mine and ROI will be fast

Please upload your mod-BIOS.

I need original BIOS for Saphire RX 560 Pulse 4GB (11267-18-20G)
I heve 2pcs of this cards and I bought with modified bios, and now I need original. Cards is making about 14.4 MH/s with Hive OS and for price they are really good, consuption about 40w in GPU-Z. Btw this is card with 896 Stream Processors and 1500 MHz Memory clock
Thanks

I am curious as well as I could really use it if its good

What hashrate you getting with this BIOS?

What driver you using? What OS?

What temps card running at?

What strap you using?

speeds & voltage set in Claymore or Afterburner or other?

For anyone that is looking for a bios for the Gigabyte RX 560 Gaming OC 4GB cards with Hynix memory, here is a bios that works great.  Use the following settings with it.  Power Limit % -15, Temp. Limit 90, Core Clock 1149, Memory Clock 2000.

It's a AMD Phenom X4 9550, MBO is GA-MA790X, I put latet BIOS.
Maybe it is MBO, my thoughts too I but have to ask and check, it's a bit incovinient to buy new MBO, Proc and RAM.

Grub parameter is already there so it's not that.

On Linux you need special kernel parameters for mining: "amdgpu.vm_fragment_size=9". Put them in /etc/default/grub, execute update-grub and reboot.

Hey Guys,
thanks for all your help so far. I think I have the overclocking and undervolting down and my two cards which are NOT rebranded 460's are getting 10.5 MH/s consistently. The other one can barely get over 8MH/s.

I think it's time to look at modding the bios but as much as I read up on it the more I need some help. There are a lot of terms I am not picking up and I would like to ask if someone oule help me out and mod these for me. Unfortunately given the scarce nature of the cards I have 3 different cards.

Even if I can get gigabyte and XFX to 13 and change that would be a 30% increase which would be awesome!
Any help you could give would be appreciated. You folks have been great!

Would have initially said check your page file, but it seems to match your 4x4gb @ 16gb.

I'm thinking here is some sort of BIOS limitation - can I ask what CPU you are using? It's not an APU is it?

There is some sort of bottleneck when you are running more than 2 cards - most of those boards are rated for SLI, but it really depends on the board with anything more than that.

I recommend maybe getting a cheap AM3 board with a Piledriver or maybe an FX6300, should run stable.

Hello all,

I have an "interesting" problem. I have four rx560 4gb GPUs, two XFX and two MSI Aero. XFX are on x16 slots on MBO, MSI on x1, on risers.
The problem is that GPU0 and GPU1 are on 12 MH/s but GPU2 and GPU3 are 5,3 MH/s.
I flashed them with BIOSes from this forum. I tested MSI on WIN10 and it goes for a 14 MH/s and XFX is max 13 MH/s.
Linux Mint, 4.10 kernel, amdgpu-pro.17.40 driver, for a blockchain.
Claymore 10.5, ETH/sia
Two PSU, 400W and 550W, MBO AM2+, quad core proc, 8 GB RAM. There's plenty hdd space, 16gb swap.

Now, the problem is that's too low hashrate on two cards, I don't have an idea how to fix it. I tries some solutions from net but no avail. Commands from claymore seems not working.
Can anyone help me with this? Would it be better if all four GPU are on risers?

I have 3 x1 on MBO and 2 x16, so I am planing for a fifth GPU but...not till I solve this problem.

I have same issue with you, how did you fixed? I can't see "GPU Workload" options on Radeon setting.

Hi,

Sorry for my English

I've tried to flash all kind of bios'ses that where posted in this tread, but atiflash keep giving me "SubsystemIDs Mismatch"

What to do? I have 4 RX 560 4gb videocards with micron mem and 2 fans onboard.

Thnx in advance

Thank you very much for your reply, Branko!

Ah, I see! Indeed, the Bandwidth goes up when the Memory clock goes up. Issue fixed

Regarding the low hashrate; You were correct once again! It was issue number 2: I had to change the workload from graphics to compute for each and every card. I just changed it for 1 card, as per AMD documentation it says: Note! In systems with more than one GPU, this option will apply to all GPUs in the system (https://support.amd.com/en-us/kb-articles/Pages/DH-024.aspx) But apparantly that is not true, at least not for my rig.

Once again thank you very much!!

Sorry for no English in rest of this reply,but its much easyest to me to talk to Branko...
@Branko drug nekoliko postova iznad sam pisao koju grafiku imam,pa me zanima jesi li se susretao sa ovom verzijom i postoji li ikakva mogucnost da se ona klokuje... Kad otvorim u bios editoru ne pokazuje mi vise od 1500 u timers,tako da u sustini ne mogu da uradim ono sto svi drugi mogu... Da kopiram 1500 u vece itd kako vec ide... E sad,skidao sam sa neta neki vec modovani Bios,mada on nije striktno za moju graficku,no u svakom slucaju ona ga je prihvatila... I uspeo sam da predjem 13mh sa njim,u principu tu se negde vrti... Ali nisam ga koristio dugo jer u sustini kao sto sam vec rekao nije konkretno za tu graficku,pa me nekako strah koristiti ga... Pa me zanima postoji li mogucnost da se njen originalni Bios moduje??? Hvala unapred...

Theres no "limitation" in bandwith, its just a number you get based on memory bus width and memory speed, so when you OC memory, you also get
better bandwidth.

12.1 is low with such big frequency, so either of 2 things happened:

1. claymore command to set frequency doesn't work (in that case, use wattman instead)
2. you forgot to change workload from graphics to compute in wattman

GL, and may the hashing power be with you

Hi guys,

First of all, this topic has been very informative. Thank you all very much for sharing your knowledge and information  

Sadly, I didn’t do my homework before buying 12 x Sapphire Radeon RX 560 Pulse 4GB (11267-18-20G). I thought I got a good deal, only later to find out this model is severely gimped. As stated before in this topic, it only has 896 shaders, less TMU, 1500Mhz and less Bandwidth:

https://i.imgur.com/lIYIFl5.png

I can’t return them anymore so I have to make the best of it…. However, it looks like my card is just a softlocked ‘normal’ Sapphire Radeon RX 560 Pulse OC 4GB (11267-00-20G). I have been able to unlock the shaders to 1024, the TMU to 64 and my memory chips are also ‘normal’ MT51J256M3 (MICRON) a.k.a. they run at 1750Mhz by default.

https://i.imgur.com/dJfr57K.png

I’ve tried different straps (from Wacko, Branko, One Click Timing from PSBEditor 1.6.7, the BIOS straps website with the Nyan cat logo and the ‘top secret’ 15Mhs strap) and was able to push this ‘gimped’ card to 12.1MH/s. Sadly, I can’t do much more because of the limitation in Bandwidth. It’s locked to 96 GB/s and I need the full 128 GB/s in order to push the hashrate even further. Changing/raising the TDP and TDC made no difference; the cards just keeps using the same wattage (which is odd I think).

My question: Is it possible to unlock/BIOSmod the Bandwidth to 128 GB/s as well?
@Branko: Do you see any room for more improvements in my BIOS mod?

For those of you interested in my ROM:
Stock ROM (without any modifications): http:// data .freek. ws/public/11267-18-20G/RX560_STOCK.rom
ROM with shaders unlocked to 1024 (no other modifications): http:// data .freek. ws/public/11267-18-20G/RX560_UNLOCKED.rom
ROM with unlocked shaders, Branko’s strap and increased max. memory frequency (for use with claymore): http:// data .freek .ws/public/11267-18-20G/RX560_12MHs.rom
(REMOVE THE SPACES IN THE URL. I could'nt link directly to my server, it got flagged my bitcointalk)

The last ROM (the one with Branko’s strap) will give you 12.1MH/s at Ethereum mining using Claymore 10.6 and the following settings: -cclock 1275 -mclock 2225 -cvddc 1000 -mvddc 850
