Questions about motherboards and ram.

Mongrel · Nov 16, 2017

Hello.

For Christmas I am going to be getting the following bundle:

https://www.awd-it.co.uk/intel-i7-7700-4.2ghz-kabylake-quad-core-cpu-gigabyte-h110m-s2h-motherboard-ddr4-hdmi-4k-bundle.html?gclid=EAIaIQobChMIs5DOuuKv1wIVhgrTCh29WwTREAQYASABEgKadPD_BwE

I am going to buy the ddr4 ram separately. I looked at the motherboard and it says says "Support for DDR4 2400/2133 MHz memory modules". Does this mean If I buy 2666Mhz it will underclock? Is the max speed ram I can have 2400Mhz?

Another question is if the max ram speed I can get is only 2400Mhz obviously i will buy that instead of 2666Mhz, but is there a big fps difference between 2400Mhz and 2666Mhz?

Thanks.

Yes the max the board can run is 2400 , you wouldn't notice a difference.

There's really no noticeable real world difference between the 2 . The H110 boards are locked at 2400.

If the motherboard says that is supports 2400/2133 MHz modules, then it would not support a 2666. Best case scenario would be that it would underclock the RAM, worst case scenario is that the RAM simply would not work. As for an fps boost, RAM does not affect your fps in any way. That is almost entirely your CPU and GPU that determines that.

For gaming their not going to be any noticeable difference.
If the 2666 cost less you can buy it. The board will down clovk it when installed.

Thanks! Another question I forgot to include was does it matter if the ram I buy is single or dual channel for that motherboard? Thanks.

jankerson · Nov 16, 2017

Yeah, 2400 will be the max that board will do on ram speed wise.

Mongrel :

You need to buy a dual channel kit.

That's 2x 4GB, 2x 8GB.

Dark Lord of Tech · Nov 16, 2017

Mongrel :

Buy it in a matching pair for DUAL Channel mode.

Will run slightly faster

Thanks! If you know any site that sells dual channel ddr4 2400Mhz feel free to reply!

Does this mean I cannot buy single channel ram? I would really prefer to get 1x8 Gb at Christmas and then save up some more money so I can Get another 1x8 gb. Will there be a problem if I get 1x8 gb?Thanks!

Needs to be a matching pair.

That's why they call them Dual Channel kits.

So if I only had 1x8gb in the ram slot it wouldn't work?

It will work with one, but if you get another 8GB it might not work in dual channel mode because they won't match. Could also not work together at all.

That's why you need to by a dual channel kit.

So can you tell me if this 'theory' would work:

On Christmas I get 1x8 Gb of Hyper X ddr4 2400Mhz ram, and then a month later I get the exact same Hyper X 1x8gb 2400Mhz ram. Would this work?

Dark Lord of Tech · Nov 16, 2017

May or may not run , Mixing modules is hit and miss even if identical and purchased at separate times.

NO, I said more than likely it won't work.

And if it doesn't you wasted your money.

The ONLY way to be sure is to buy the Dual Channel kit.

They are matched pairs to work in dual channel mode.

Mongrel · Nov 16, 2017

Wow this really sucks

I was hoping to get 8gbs at christmas and then just get another 8 soon after.

jankerson · Nov 16, 2017

Mongrel :

Doesn't work that way.

Dark Lord of Tech · Nov 16, 2017

Identical you have a decent chance when mixed at separate times but not Guaranteed to.

Mongrel · Nov 16, 2017

Thanks for the help everyone!

jankerson · Nov 16, 2017

Only if lucky enough to get them from the same batch, then maybe an outside chance.

Like playing the lottery....

Mongrel · Nov 16, 2017

jankerson :

I just done the maths and it should work out! I should have JUST enough to get the bundle + 16gb of 2400Mhz ram included with it. Thanks for the help everyone!

There you go, you will be set.

That's a 2x 8GB Kit right?

Yes, it comes already installed with the bundle!
