2 or 4 modules RAM

[aggelospan]

Hi everyone,

 

My first built, after using internet cafe for 15 years so forgive me if the question is stupid.

I got an MSI z490-A pro motherboard with a 10700k processor.

My ram of choice was this : G.Skill Ripjaws V 4x8GB DDR4-4000MHz (F4-4000C18Q-32GVK)

However after seeing a video on youtube stating that if your motherboard's channel is dual there is no point on going 4 modules,

i am having second thoughts on whether i made the right choice.

Should i go for 2x16gb at 3600mhz C18 instead?

 

Thank you in advance

 

PS. Gpu is RTX 2080 super if it makes any difference or is needed to answer my question on what to do

what will be the main purpose for this build?

Welcome to the forum!

 

If you already purchased that 4x8GB kit, you might as well leave it. It's just that you won't be able to upgrade to 64GB without replacing your current memory.

If you didn't, then yeah go for a 2x16GB kit, but don't go for 3600MHz CL18. I'd get at least something like 3600MHz CL16 or a 3200MHz CL14 B-die kit and do some overclocking with it.

Your CPU only supports dual-channel so 4 RAM sticks don't give you higher performance than 2. Just leave it as is because 32GB will do fine for a long time.

Gaming. Mainly PUBG and COD warfare.

I have ordered it and i suppose i can change it, but only if it wont perform as well as the 2x modules or something like that. I dont want to change the order if i dont have to

Bandwidth wise 

It's the same since every LGA 1200 cpu only has 2 memory channels 

So your only gaining capacity but your putting more pressure on the imc

16 gigs will be fine in this case 

Just go for a cl16 3600 kit and you'll be fine

If you only game just go for 2x 8GB and call it a day. You won't benefit from more memory...

What i dont understand is: since my CPU only supports dual-channel, is there a drawback on using 4 ram sticks? Or is it just that i will get the same performance as i would get from a dual module 2x16 ram? If its going to perform worse with my 4x8gb only then i will change it

There is no real drawback to using 4 sticks. But the CPU just won't really take advantage of more than 2 sticks. For example 2x16GB should perform the same as 4x8GB.

Thank you very much. This is essentially what i was asking. Since the difference in pricing is only 20euros, i dont want to get into changing the order for no reason.
