Is this upgrade compatible with my computer?

We guarantee our memory is 100% compatible with your computer. How can we make such a bold claim? It is combination of quality product, vast industry knowledge and experience and the Upgradeable system we built to help customers find an upgrade for their specific computer.

You may have noticed our website is different from any other. It is not your typical eCommerce web shop. We do not get a list of products and categorise them, making you do all the work = which is the best upgrade? Our website is a configurator. We have taken all guess work out of buying an upgrade. Our technicians and engineers match the right memory upgrade to every computer we list. We do this in a unique way, which is the Upgradeable secret sauce. Our history and experience is in designing and manufacturing of computer components. In fact, in 1990's we were the first company to make a third party memory module in Australia at The Research Park, Bond University in Queensland. We have condensed all that experience into a system that rates a components quality. If it meets Upgradeable's stringent quality guidelines, then we list it as an available upgrade. That is why we can offer a lifetime warranty, and fast delivery. Who loses if it is not compatible? We do because we pay for the shipping charges and you get a full refund or advanced replacement!

Our goal is to delivery the right upgrade the first time. Look at our reviews, they say we deliver on what we promise.

Lifetime Warranty

All RAM upgrades supplied by Upgradeable have a lifetime warranty.
Our definition of lifetime warranty is: If the product ceases to work at anytime, you can return it for a replacement. Simple. No if's, no but's. Our RAM will out last your computer. We have had the same warranty since year 2000. It has never varied or been modified. Our competitors have played catch up and matched our warranty but they can never match our service. We don't provide a lifetime warranty as a gimmick, it is a statement on the values of our company, our goal of exceptional customer service and the quality of the products we supply.

Five year SSD warranty (3 year OWC Aura)
Unlike RAM, an SSD has limited write cycles, so it will eventually wear out. The Crucial MX500 is rated to last 360TB of write cycles. You would have to write 200GB every day for five years to wear it out! The new warranty for the MX500 SSD is five years. Our faulty SSD return policy is to make it as simple as possible for the customer. We will replace faulty drives as soon as they are returned. Please note older Crucial drives have a 3 year warranty and some OWC Aura SSD drives we sell have a 3 year warranty. The new Aura Pro X has a 5 year warranty.

14 Day Money Back Guarantee
When we started Upgradeable, we needed to assure customers our RAM would make a difference. What if the RAM upgrade did not speed up your computer? The answer is you can return the memory for a full refund. We chose 14 days because we thought that was a reasonable time frame. We have never refused a refund that has been a reasonable time past 14 days, such as 21 days or 30 days. If you are not happy with the RAM upgrade, we don't want to make your day worse by saying no to a refund. In fact, everything we list we stock, so if you dont want it, we restock it. This is a point in difference to most Kingston resellers. They don't stock the product, they are selling from someone else's warehouse. Which is why they don't like refunds.

Our money back guarantee is about your assurance that the RAM will make a difference. If is not about how many days, it is about customer service and trust. We have had the same guarantees for 18 years because they are sustainable. We plan to be here servicing our customers for more than the next 18 years!
