Hi Hape, we will explore into 4GB possibility. One question, why need such high capacity? for what type of application?
According to the A64 User Manual:
Quote:2.1.3.2. SDRAM
- Compatible with JEDEC standard DDR2 /DDR3 /DDR3L/LPDDR2/LPDDR3 SDRAM
- Support clock frequency up to 667MHz(DDR3-1333)
- Up to 3GB address space
- Support 2 chip select
- 16 address signal lines and 3 bank signal lines
- 32-bits data width
- Support Memory Dynamic Frequency Scale(MDFS)
Question answered
BTW: Which type of DRAM are you going to use and which clockspeeds you found to be reliable?
Current board using Samsung K4B4G1646D-BCK0, 800MHz, and here is the datasheet link: http://www.samsung.com/semiconductor/glo...Rev102.pdf. Please note that from time to time, we may change DRAM vendor pending on market availability.
