MacGurus Memory

We carry only the finest quality memory available today. This isn’t sub quality overruns bought at auction but only premium quality and manufactured to the highest tolerance possible. MacGurus RAM is warranted for life from failure. This is the same memory carried in past years by MacGurus and all memory sales prior to 2003 by MacGurus of Wilmington Delaware are still covered under this warranty.

MacGurus has been with the same memory supplier since 1995. The nature of the RAM market requires the need for a dedicated testing, evaluating and purchasing facility. We have that service in place. We are analyzing, testing and stocking the best quality RAM from several manufacturers every day. With one of most every Macintosh model on hand for quality and support testing we are able to verify quality and specification needs across the Macintosh spectrum.

We make no bones about it, we are not in the discount low cost RAM business. We search out and purchase only the best for our customers. Poor quality RAM is the bane of any computing experience. The costs in data corruption with the inclement possibilities for data loss, repairs, lost time and frustration have led us to the inescapable conclusion that top quality is worth every penny spent. We are proud of this stance and are dedicated to maintaining this standard.

NOTE: If you are at all unsure of what RAM to order - please email or call us. Our technicians are available and more than happy to assist.
