Hi guys.
Building my first mining rig.
As u guys know RAM ddr4 is expensive these days.

Can I mine using ddr3 or ddr2 which is so much cheaper.
Also most ppl tell me 4GB is enough.
Do u guys recommend 2x2GB or 1x4GB sticks?

Will be using 3x Vega 64 for mining. Adding more GPUs later.
Using Asus Prime H270+ CSM motherboard.


Thanks
