check Memory Error on Hwdinfo. If you have error reduce MEM. The goal is to have ~1% of error or zero

Diddnt happen

PS. Let me know the result, please.

Only problem i would like to try is there any impact to unlock it to 1024 shaders.
I cant use your bios, because difference in memory. Any chance you can have a look and try to unlock shaders to my card as well?
Here is the original BIOS: https://www.upload.ee/download/7968607/6c834c23777f12f89aa5/RX560_sapphire_hynix.rom

All of the cards accepted it

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:

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.

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

Thank you very much for your time

Funnily, they do. I will force return two of them cause seller had them advertised as 7000mhz memory (even for gaming these are sick!)
I found by a complete fortune, that the Techpowerup bios (only one) is the same device ID by sapphire and is the 16 CU variant..... All of the cards accepted it, but i think the TDP difference being big (this link is probably for the Normal Sapp pulse 16 cu, with higher TDP) my main gpu one was struggling and choppy, but yeah, all of the 4 cards worked.... i just rolled them back to the 14 cu one, cause well, 6000mhz base memory speed sucks much.)
I do 420 h/s and 14 mh/s max with them on the 14CU original bios with timing mods with PBE

R0land, i really respect you man, used your Hynix MJR timings for my 580 8gb (complete rip off/downgrade compared to the lower priced aorus 4gb).
I have to say though, both your strap and that experimental xmr one do BSOD without errors within 2075-2100 mhz memory... not sure though, If those cards never give error, can i just use PBE straps and 2300++ mhz instead? whatcha think?
also your micron one, is it different than the PBE one? better you think?
I can share/ give access to any of my cards (2gbs gigabyte powered and non, also have access to 4gb non powered,strictly micron only (gigabyte too) )

Have you ever managed to unlock 1024 on the sapp 560d? I had no such a luck
Btw, my sapp 560d cards work at 2025MHz and give ~13.3-13.4Mh/s ETH

please upload your Bios ;-)

Try MEM 2080 and if not working reduce MEM... Seems your card is not supporting high memory.

Sapphire 560d 4gb is a garbage!!!!I didn't even try unlocking the CUs again. The memory reaches 2000s barely!

please upload your Bios ;-)

The Micron strap RX560 ... 15,2 eth ... 480 xmr :

777000000000000022AA1C0073626C41B0551016BA0D260B0060060004061420EA8940AA0300000 01914292EB22E3B16

or use OneClickPBE.

ram must be at least 3gb.

Is this just for ETH or other algos as well? I am trying to understand whether the custom timings work overall and increase the performance or they are good just for certain algos?
I searched a bit through the bits.media forum but couldn't find specific thread for RX560, only found 570/580. Can you please advise?
