Best RAM by far. The size and speed are perfect for coding, video editing, some gaming, and even 3D work.

Highly recommend checking whether your motherboard or CPU supports the 64GB limit otherwise, you can save some money by going with the 32GB kit instead.

Important note: After replacing your old laptop RAM with this kit, your laptop may take about 2–5 minutes to boot the first time. This is normal, especially when upgrading from 16GB to 64GB, as it’s a significant jump in memory capacity. Once it’s up and running, your laptop should feel much smoother and more responsive.

The performance is satisfactory; however, it has been observed that the modules operates toward the upper limit of the specified temperature range, though still within acceptable parameters.

I run an Acer Predator Helios 300 PH315-55
I installed these 2 memory sticks, reassembled everything, and hit the power button.
The Turbo light (utter top left on the keyboard) instantly came on.
As recommended, I left my laptop on, to do it's thinking thing.
This is required, as the motherboard needs to reconfigure the new memory before it starts booting up.
My laptop sat for about 2 minutes (some people have had to wait up to 5 minutes), just with the Turbo light still on, then I heard the fans spin up.
Immediately, my system started booting up, and I hit my Windows11 login screen, in a matter of seconds.
I logged in, and checked, and voila, it was now showing 64GB of system memory.

There is a HUGE performance difference, coz I run a lot of active programs and multiple browser tabs.
On 32GB, I was constantly hitting only 5-7 GB available, which caused programs to hang, wifi to drop, vid calls to stutter, etc.
Now, I'm averaging 35GB available.

My system is snappier, and running noticeably cooler, with the fans not spinning up near as much.
I am just mind blown at the performance difference.
My laptop is beastly again!!

Wootware are legends for their advice, and for stocking such awesome product brands!

Firstly, kudos to the WootWare team, for their support and professional service on this item.

Installed this in my new WootBook Laptop and not regretting it.

Running on office mode, the system run cool as a stand-alone unit.
Doing gaming on balanced/turbo mode, as with any laptop, it tends to run a bit hot. I would strongly advise in setting up some cooling for doing gaming.

Overall rating, 10/10
