Is 1866mhz RAM compatible with my Motherboard?

[mja2106]

Hi,

I'm looking to upgrade the RAM in my system, but I'm unsure whether it will be compatible with my motherboard.
My motherboard is the Gigabyte GA-Z77-D3H.

On the website it says Support for DDR3 2800(OC)/1600/1333/1066 MHz memory modules

I currently have a 4x4gb 1600mhz kit running fine. I'm looking at 32gb, these specifically:

But I'm not sure how it can support 2800mhz and not 1866.
So would I be able to put them in and have them work straight away, would I have to fiddle with some stuff or would it not work it all?

Thanks.

It will not run at 1866mhz but you can still install it.

Your motherboard is only compatible with DDR3-1066/1333/1600

Essentially your 1866mhz ram will be running at 1600mhz (downclocked)

So I don't need to change the speed I run it at in the BIOS or anything, I just put it in and turn on the PC?

Yep good to go it just won't let you reach those speeds.

You install the 1866 MHz ram first. Then go to ur bios to see what speed it is running at. Your bios should state 1600 Mhz since that's the fastest ur board can run. Also check if XMP is enabled, if it isn't then enable it. It will use the settings of the RAM so you don't have to do anything.

The GA-Z77-D3H allows him to install and he's set.

Or would I be better with some 1600mhz CAS 9 like this:

If you haven't already purchased the 1866mhz ram go for the 1600mhz which are generally cheaper.

 

[mja2106]

the 1600 is £25 more but it's CAS 9, not CAS 10, so shouldn't it be faster if they both run at 1600mhz

 

[symsus]

Yes of course, ram like graphics cards have different models. It's whether you want to spend more or less for better speeds

1600 cl9 is pretty much the same as 1866 cl10.
Get the cheaper one.
I heard that the faster rams are there for oc without voiding the warranty
