Laptop memory 8GB(4GBx2) DDR3/PC3 12800 1600Mhz

These RAM cards fitted into my Acer Aspire E1-571 very easily following the directions given. When I switched on there was a blank screen - so I removed them and rubbed a pencil eraser on the connection strips ( as suggested) and replaced them and they worked. However, there was a big lag between logging onto Windows 10 and the home screen. I looked in the System folder and clicked on About and noticed that although the installed RAM said 8GB the usable memory was about 3GB. To cure this annomaly in the 'Type here to search box' I typed in msconfig and opened that setting. Clicked on the Boot tab. Ticked Maximum memory. This highlighted 8192MB. Clicked on OK. Then back in the previous screen clicked Apply and Then OK and closed it. Now the home screen comes up quickly and the machine is a lot faster. I checked the available memory and it is now 6.58 usable!

I originally selected memory modules for my laptop using the Crucial memory selection tool, however the modules it directed me to did not work (the laptop recognised them but rebooted every time the OS loaded). After some extensive Googling I discovered the problem might be the number of chips on each module. Crucial's offering had four chips, but my original modules had eight. I looked around and found the modules I am reviewing.The product description offered an email for enquiries about compatibility, which I used and was told in a prompt and friendly email that they were compatible. They were! They arrived securely packaged in a metal tin, lined with dense foam padding. This seemed very secure and unlikely to pose a static risk. They fitted well and the OS loaded successfully. Good job all round!

Great price, speedy delivery, and quick and easy to fit. Has given my previously painfully slow MacBook Pro a bit more of a kick but I think I now need to swop the HDD to a SSD to get full benefit. Overall I was impressed - it was a pretty seamless switch over. Many thanks.

Quick and easy to install. Will use this company again,

Excellent presentation in aluminium tin. Appear to be excellent quality.Have utterly transformed a rather long in the tooth 2012 Mac mini running the latest MacOS into a lean, mean fighting machine! Once again, can have several safari tabs open whilst working on several programs with no beech ball or slow down. For a 9 year old (!) processor I find this astonishing tbh. But, this is probably why Apple removed user upgradability In the later Mac mini’s.Anyway, excellent product. I’m over the moon .

It's memory. It worked. Nuff sed.- except that it comes in a cool tin, so you can put the old memory in the tin, and put it in a safe place in case you ever need it (You won't. 35 years of computer engineering I have NEVER downgraded a computer back to a lower spec.) But the tin nonetheless pleased me no end. Little things..Oh yes - and the supplier correctly identified it as fitting my specific laptop. Got to give them points for that. There are so many kinds of memory in use these days, that was a bonus.

I didn't think that these were even going to work as they arent a brand that I've heard of ever. So I thought well as Amazon are on the buyers side I'd give them a try. Flawless 👀 didn't expect that. Also they was packaged in a nice metal tin with padding. I was very impressed. Quality top notch, price point is great, and the ram build itself has quality finish and quality components.Give them a try 😁

It worked and I like the tin it came in
