Hello all, and sorry for my english.
But, I have card Sapphier nitro+ RX580 4GB (Elpida) oc with moded bios, strap from 1500. If I set the memory clock over 1900MHz it stops running, restarts the driver and on monitor are green checkers.
This problem has the RX 570 (Sapphire nitro+ oc) of the same type and memory. Problem over 1850MHZ
Can you help me pls? THX

Each block is stacked on top of the previous one. Adding another block to the top makes all lower blocks more difficult to remove: there is more "weight" above each block. A transaction in a block 6 blocks deep (6 confirmations) will be very difficult to remove.

Try swapping the riser and running it with the default core voltage if you are undervolting the card. The 1500 MHz timing straps are too aggressive for many cards. I use the Polaris Bios Editor v1.6.2 'one click timing patch'. It automatically detects each memory type and adjusts the 1750 MHz and up straps with the bundled performance straps. PBE v1.6.3 and up adjusts the straps from 1500 MHz and up, but the 1750 MHz straps are more stable. https://github.com/jaschaknack/PolarisBiosEditor/tree/9ec64066eecdb55ac86da7bc82181eaab2161d51

I tested the new settings, but as soon as I set it above 1900MHz the graphics crash.
With new driver I have 26.5 Mh/z, it's good but graphiic have more potential.
Motherboard: Asus prime Z270 Plus Pci-e Gen2 Procesor I7400 8GB ram
Thank you.

Same trouble here, 3x RX580 Nitro+. While my two older cards are fine with 1500 or 1750 straps @ 2000MHz, new gpu i got last friday crashes if memclock is higher than 1900 MHz.
According to srbv3.2 all cards got same Chip and same mem type/model.

Yes. I run the pixel patcher because I have RX 480's and 570's on the same rig. The RX 580 dosen't need the pixel patcher with a modded Bios.

Flashed my cards with PBE 1.6.4 and running FCU 1709 with Blockchain Aug23 or 17.11.4, no difference.

Try Aug 23 drivers + this bios: https://www.miningtweaks.com/sapphire-rx-580-nitroplus-4gb-elpida-bios/ (Elpida) I get 30MH Eth solo mining, 29.3 with decred/lbry, 790H/s Cryptonight, all with Claymore. My cards have Elpida memory as well. By far the best value in a mining GPU so far! I undervolt and overclock directly in Claymore: -cvddc 825 -mvddc 825 -cclock 1150 -mclock 2050 -powlim 0 for ETH. If you have a rig, i.e. several cards, set Windows virtual memory to 16 or even 32GB. Also, try setting PCI-e to Gen1 in mobo bios, sometimes that solves some issues as well, don't ask why.

Thats actually very common with Elpida memory.
Funny thing, my Sapphire and XFX 580's that came with Elpida memory are having a hard time reaching 2000mhz, while the shitty Gigabyte 570 gaming 4G are stable at 2000mhz, but their cooling is so bad compared to sapphire/xfx.
I dont know how card makers set up the memory to be different than others.. for instance, I got a few 580 Power Color Red Dragon Gold that came with Samsung memory, and other Sapphire 580 Special Edition, also Samsung memory The power color cant overclock past 2100mhz, while the sapphire easily hit 2250mhz

It is recommended not to buy the standard variant of these cards but the overclocked version. For example sapphire RX580 nitro+ special or limited edition as the chips used for these are selected and thus you stand a better chance with them for mining. I have for example 6 Sapphire RX580 nitro special edition with 8 GB hynix memory and modded bios. I run them at GPU 1150 and MEM at 1200, voltage - 30 and powerlimit - 7. They are running stable at 64 degrees and produce 31 h/s ethash and 840 h/s on cryptonight.
