Hi,

I have 2 mining rigs :
1. 4 RX 580 8 GB (MSI) and 2 RX Vega 56 (Power Color Red Devil)
2. 5 RX Vega 56 (Power Color Red Devil)

Both installed win 10 1709, AMD driver18.5.1 & mining normal_v7, but why in rig 1, I can set RX Vega with MC 920, but in Rig 2, the max MC I can set is 895 without any error??

1. Rig 1 SS:
GPU0 :    1131 H/s [T: 58c, RPM: 3105, CC: 1366 MHz, MC: 2050 MHz]
GPU1 :    1001 H/s [T: 58c, RPM: 3155, CC: 1366 MHz, MC: 2050 MHz]
GPU2 :    1123 H/s [T: 60c, RPM: 3091, CC: 1366 MHz, MC: 2050 MHz]
GPU3 :    1128 H/s [T: 60c, RPM: 3172, CC: 1366 MHz, MC: 2050 MHz]
GPU4 :    1878 H/s [T: 57c, RPM: 2368, CC: 1408 MHz, MC: 920 MHz]
GPU5 :    1885 H/s [T: 53c, RPM: 2349, CC: 1408 MHz, MC: 920 MHz]

2. Rig 2 SS:
GPU0 :    1838 H/s [T: 57c, RPM: 2368, CC: 1408 MHz, MC: 895 MHz]
GPU1 :    1824 H/s [T: 60c, RPM: 2358, CC: 1408 MHz, MC: 895 MHz]
GPU2 :    1836 H/s [T: 54c, RPM: 2402, CC: 1408 MHz, MC: 895 MHz]
GPU3 :    1835 H/s [T: 62c, RPM: 2391, CC: 1408 MHz, MC: 895 MHz]
GPU4 :    1841 H/s [T: 59c, RPM: 2652, CC: 1408 MHz, MC: 895 MHz]

Any ideas why this is happening??

Also, need help how to flash my Vegas from 56 to 64, already tried with the rom provided https://www.techpowerup.com/vgabios/196853/Powercolor.RXVega64.8192.171114.rom, but still cannot flash, if im not mistaken the error is different file size.

Any help appreciated.

Thanks
