- We aggressively price shop a large percentage of 3rd party manufacturers for assembly of our original A-Tech branded memory. However, we never compromise the quality of the chips in our products and only use A grade major brand original chips, or our own hand selected A-Tech branded chips. Older generations of A-Tech branded memory can also include relabeled, original modules from Samsung, Hynix, and Micron with boards and chips in cosmetically new condition. We have a very unique supply chain that allows us to incorporate overstocks, liquidations, open box/sealed returns, pulls from brand new systems, and memory in cosmetically new condition from bulk purchases and a vast broker network. We are a large distributor of other brands of memory, as well. We pride ourselves in carrying the largest selection of brands and part numbers in stock. All new condition modules fulfilled by A-Tech may include open box returns. Incorrectly ordered memory is very common in the tech industry and often times these modules were not put into use, rather, they were simply exchanged for the correct memory upgrade. Keeping this in mind, we fully test these modules and back them with our complimentary A-Tech lifetime warranty. All the brands that we carry as well as our A-Tech branded memory carry a complimentary lifetime warranty through A-Tech Components. The original purchaser of the memory will always have the right to return a module that is defective on arrival or after great use for a working replacement. This lifetime warranty applies to both new condition modules and used condition modules. See More
