Hey pplz! We measured the speed of "Fast RAM" and our results show, that "Fast RAM" is not so fast, as the processor frequency allows, the Sprinter computer runs in Fast RAM on about only 16.1 MHz (in slow RAM it was about 10.8 MHz). Why, if processor tact is 21 MHz and the RAM is FAST, it means no waiting for SLOW memory?

Yes, BIOS 2.12.251 has a lot of 'wait' commands. And FastRAM not useful yet.
But BIOS 3.00.253 has not any 'wait' for usage FastRAM. You will can testing it after publish new BIOS in April 10.
