Is it possible to adjust DRAM frequency of Roseapple Pi, for testing purposes?
You can try From what I see and it's the bootloader that initializes the DRAM.Look at the:bootloader.iniDRAM default speed for the roseapple is set to 588MHz (0x24c)
Thank you, fritz.Hope with properly configured DRAM frequency, Roseapple Pi would compete well with others new fruitboards in terms of performance.
672Mhz(0x2a0) - OK.
Have you tested reliability or only if it boots?Well a rvrewop-memtester would not be bad to have.
Sure. Tested with debian memtester and CPU@1308Mhz@1.325V(big heatsink) for more than 24 hours. BTW, testing continued.
OK. After hours of testing with reduced to 1.3V(1308 MHz) CPU voltage bits flip occurred.Don't know is it related to CPU voltage or something else.(temperature?)Back to 1.325V.
