How much RAM can be added to this motherboard?

Question

Overclocking

Good afternoon !
1) How much maximum RAM can be put on this mother?
2) Is it better to buy with a frequency higher than 1600 Mhz than 800 Mhz?
My PC is HP PRO 3500 series MT
CPU: DualCore Intel Pentium G2120, 3100 MHz (31 x 100)
Mother: Foxconn 2ABF (63-0100-000001-00101111-122211-Chipset$CU3816_BIOS DATE: 07/17/13 09:40 :37 VER: 04.06.05)
Supported memory types DDR3-1066, DDR3-1333, DDR3-1600 SDRAM
Thank you for your attention!

Answer 1

1. The maximum you can put is 8 GB with a 64-bit system.
2. Yes, the higher the frequency, the better. Buy at 1333 MHz because the processor supports only 1333 and 1600 MHz, and the mother supports 1066 MHz and 1333 MHz.
