Hi.
I'm running into an issue here. I recently bought an RX 590 (Gigabyte) and it has apparently a new set of Samsung memories (K4G80325FC) which are unrecognized in PBE 1.7.2 for the "one-click mod".
I would vastly appreciate if this could be made to my card, the BIOS mod.
If it is any help, it is a "Revision 2.0" model of the RX590 from Gigabyte.
Any extra information you could need I could provide.
I am only achieving 27.5 MH/s in ETH/ETC Claymore/Phoenix, when I was doing 30.5 MH/s on my old Asrock RX 580 (8 GB)
I am highly interested in making this work for these cards for everybody, so if you guys need any extra information about the card, just ask away.
Many thanks,
Juan. - Buenos Aires, Argentina
Hello, i have same problem with memory
Samsung : K4G80325FB08 00 00 67DF Polaris30 M25P40/c 80000 pass 113-4E3661U-X6M
Bios:
https://www.techpowerup.com/vgabios/208250/sapphire-rx590-8192-181220Model: RX 590 Nitro+ Gold Anniversary Edition (5OTh)
I tested with the 1.7.5 / 4 / 2 same problem.
I click, put the patched bios, restart the pc and unknown card
Please add support memory please, tks

K4G80325FB is supported from like 1.4 version of PBE maybe even sooner. It was one of the most used Samsung memory type in RX400 series. All PBE 1.7.x versions from our Github supports that type and applies Ubermix timings. The bios you've linked seems to be working as expected with PBE 1.7.5.
K4G80325FC is one of the latest Samsung memory and it's supported since PBE 1.7.3. Ubermix doesn't fit on this type.
