I saw that when over clocking A31 with AnTuTu the PLL1 Tune changes. I have no clue or any documentation as to what this her does (the function of its bits). Anyone has any idea? Raanan On Sunday, August 31, 2014 11:59:29 AM UTC+3, RFat wrote: > > Hi Siahrhei, > > Thank you for your suggestion

Hi Siahrhei, Thank you for your suggestion. I believe I am turning on the cache by calling: void cpu_dcache_enable(void) { u32 reg ; reg = get_cr(); timer_delay_ms(1) ; set_cr(reg | CR_C); } void cpu_icache_enable(void) { u32 reg ; reg = get_cr(); timer_del

Hi all, I am trying to overclock the A31 higher than 1008MHz and I am getting deterioration in performance. The way I work is execute a small program from u-boot which redefines the N multiplayer of PLL1 and then runs some CPU-intentive routine (to measure performance). Here are the results I
