Important Notes:

You can install different sized modules together in your machine. For example: Installing 2 x 8GB alongside 2 x 4GB will be 100% compatible.

Mr Memory recommends you install modules in pairs for Dual-channel performance - View Dual-channel Memory Video.

⚠️ To confirm your machines currently installed memory speed, use our ScanMyPC App. Please order the same speed to ensure compatibility.

CUDIMM/CSODIMM support varies by processor. Some CPUs may only boot at lower default speeds or may not boot at all with these modules. You can adjust memory speeds manually after boot. Future BIOS updates will improve compatibility.

To get the best performance and speed from your Motherboard, upgrade to the maximum memory.

We always send brand new matched modules, when you order 2 or more.

First Class all round!

I don't use Mr Memory frequently but have bought from them for many years when upgrading my (and extended friends and family's) various computers or replacing hard drives. I have never had cause to contact them outside of the normal process because a) everything has always been spot on and b) I haven't been a numpty before and ordered the wrong thing! So the most recent transaction with them has been a wholly enjoyable experience and totally different from any other contact I have had with any other company.
I ordered PC memory, when I should have ordered laptop memory -totally my fault! - and upon completing the returns details (which is all free post by the way!) I received an email from a wonderful person named Zoe, who happens to be Head of Operations, within 30 minutes giving me a return reference and asking what I wanted to exchange it for (the return request was for replacement not refund).
I replied with my brain fart issue and stated the laptop memory needed.
I received a very fast reply stating the laptop memory will not be in stock until the following Monday.
I then - being the awkward customer I am - asked if it could be posted to a different address as I was on a bit of a time crunch. Zoe replied saying it wouldn't be a problem. I then asked how I could pay the (very small amount) difference..... and she replied saying that they wouldn't charge any more than I had already paid!
If anyone out there doesn't agree about the absolute first class customer focus and service after hearing all my issues and stupidity that Zoe dealt with....
I have no words!
Thank you Zoe and Mr Memory, I am very glad I purchase hardware from you and will continue to do so!
