Single stick vs dual stick

[Jaspreet_816]

So actually i am planning to build a PC with AMD Ryzen 2600 and was planning to go with 2 x 8gb sticks tridetz rgb(3000).
Now because of my budget i find 1x 8gb tridentZ RGB stick (3000mhz) and i also find hyperx 2 x 4gb (2400mhz)(which is actually 1x4gb stick which i am buying 2 peices)
Now i know that ryzen performance is dependent on higher memory speed. And if i buy single gskill stick i can i will have enough room for future upgrade.

Which one should i buy.
*My motherboard have 4 dimm slots

with Ryzen, you will always want a matched set to get the benefits of Dual Channel memory. Go with a single stick and you will be sorry, get the Hyperx 2x4

then get more memory, all new if you want down the road

A couple of things here.

1. You will loose quite some performance for not going dual channel.
2. Adding a second stick later, there is a chance it wont work together. Specially on Ryzen builds as they tends to be RAM picky. The 2nd gen not so much as 1st gen Ryzen but still.
3. This also goes for buying 2 times 1x4 GB stick. Always buy RAM in kits to make sure they will work together.

Hyperx ram is not available as kit actually i will buy 2 sticks individually

then find a kit from Crucial, don't buy singles, not guaranteed to work

Yeah, or Corsair or the many others. Just look up the motherboard QVL list and find a kit that is supported.
