Aurora R5, 2133MHz RAM, overclock issues

What RAM is in it? You need RAM with XMP profiles to make that work.

Thank you, I appreciated for such quick reponse. Currently my PC has 2 sticks of 4GB Hynix RAM, which in total 8GB for now and I would like to upgrade to 16GB. 

From the service manual:

Alienware Aurora R5 has four DIMM (RAM) slots, which are accessible by removing the left-side cover and rotating the power-supply unit. Your computer supports 4 GB, 8 GB, 16 GB, 32 GB, and 64 GB DDR4 memory of up to 2133 MHz and up to 2400 MHz with XMP (optional).

R5 service manual 

You would have to add 2 sticks of 4 GB, but XMP will only work if the original memory is XMP. XMP was an optional upgrade, so you would have to check if your current memory has XMP profiles. Otherwise you will only be able to use the JEDEC profile at 2133 Mhz.

The R5 is a bit of an older machine, so there's no direct FAQ available for it that @DELL-Chris M made.

He did make an FAQ for a few utilities, and you can use CPU-Z to determine if your current memory supports XMP or not. You would look at the SPD tab. That picture in the FAQ is a good example, as that does not show any XMP profiles. He must not have purchased the optional XMP.

Utilities FAQ 

OK thank you for all the helpful information that you mentioned. I also noticed from the videos that I looked up before that people were mentioning about CPU-Z. But could you tell me how could I find the CPU-Z in my computer or which website I could download from?

You only have JEDEC profiles available for that memory, no XMP profiles.

The screenshot below shows the difference, I circled it in red.

I already found and downloaded CPU-Z and here are some information from it, could you take a look at them and see if my current memory has XMP profiles or not.

OK I got it. Now I could eliminate the thought of just adding two more sticks on the original RAM. So what if based on my current computer sets, could I just buy and replace the original 2 sticks with another 4 sticks of brand new other RAM with XMP profiles without changing another components of my current PC sets (such as motherboard or CPU)? Is this thought is gonna work or I would have to change specific component in order to make my current PC to work with a faster RAM speed?

Thank you Vanadiel & r72019. I am glad that I had post this question before I decide to purchase the RAM. You guys are very helpful and thanks a lot for all the suggestion.

I would recommend purchasing from Kingston for the R5. You would not need the VLP version as there should be no issue with clearance.

Incorrect link, wrong pc.  That's the Intel HEDT R5 desktop. The Aurora R5 is unlikely to support the linked compatible speeds.  

Thank you so much. So any of those 5 RAM list under the kingston link could be the right fits RAM for my current PC right? So I just need to simply get 2 sticks of those and be able to replace my original RAM?

And I also have another question, so let's say if I already buy those new RAM and insert to my PC, then when I enter to my BIOS, under overlocking feature, it would show up the enable option by itself once I put the new RAM with XMP or I need to do another action in order for the overlocking feature to be able to select?

I edited the error, thanks for pointing it out.

The correct link should be: Aurora R5 memory 

If supported, it will show up as an option in BIOS as soon as it is installed.  Remember to clear CMOS before booting up with the new stick. 

If you purchased an un-validated (and officially unsupported) RAM speed, like 2666, that was not supported at launch, if you encounter issues your best bet of getting XMP to work is to update to the latest BIOS version available for your PC. 

Thank you so much for answering all my concerns. I will follow the step and give it a try and definitely gonna come back to this post for the update. Appreciated for all your suggestion.
