Title: Biostar rx560 4gb low hashrate
Post by: amd1361 on July 31, 2018, 11:11:45 AM
hi there
Can someone help me with Biostar rx560 4gb card. Although it has 4gb micron memory , it cannot do more than 12.2 mh (claymore ethereum) with a modded bios (one click timing patch in Polaris bios editor)
Memory in MSI after burner cannot go more than 1700 (befor and after modding the bios)
Any help or suggestions guys?
Please let me know

It seems the highest you will be able to push that card is around 14-15 MH/s for Ethereum.

What are your parameters for your mining software?

I would say that 1700 is set as max memory clocks so you need to set it to higher clocks in PBE. Micron timing in PBE 1.6 is not very suitable for RX560 and 460.
My edit of PBE has built in Micron that is made for 560 and also it auto adjust the memory limit in bios to 2300MHz which mostly Micron in RX570/580 can reach.

I think this is because of ETH dag size increase because most of the AMD rx series with 4gb memory hashrates drops a lot.
So it's normal that you are getting low hashrate.

According to the article 30% hashrate will drop for AMD with 4 gb memory.

That was a year old DAG epoch issue which AMD fix with compute workload.
