Hey,
I am buying a pc and it has 4 ram slots,so should i buy 8gb single stick ram or 4gb double stick ram? Its frequency is 2400mhz. I am not gonna add a dedicated GPU now (but surly add one in future) and I'm using i5 7500 with intel HD 630 integrated graphics.

What ram should i buy?

8gb single stick ram,
Or
4gb dual stick ram?

Thanx in advance!!!

If the single 8GB stik of ram is cheaper, go for that. If the 2x4GB kit is cheaper go for that route. I would like to bring one point to light though, if you end up buying a single 8GB stick of ram, and plan to upgrade in the future then you must make sure you buy a kit or a 2x8GB/4x8GB kit. When upgrading rams it's best practice to buy a matched set of sticks, preferably a kit.

Second point to note, you're working with an i5-7500 which leads me to assume that your motherboard is going to be a B150/B250 chipset so the effective usable memory bandwidth will be 2133MHz. In that light, if the cost of 2400MHz rams are cheaper than 2133MHz ram's/kits then stick with the cheaper route. The extra bandwidth wont be used but the money saved can...

It is the same thing. However running 2x4 gb of the same ram will give you the dual channel configuration. This may help in tasks like video rendering. Not a big deal though, in real world you may not notice the difference. I would buy the 8 gb ram and add another 8 gb in the future

Mind sharing a link to the rams?

you can run as many sticks of ram you want whether your motherboard has 2 or 4 slotrs for ram but down the road if you're looking to upgrade you will have to either see if the exact ram is still being sold or you will have to buy a whole new set of ram cause you will start running into problems when you start to mix and match different sticks of ram
