Do not buy from this company. Their stock numbers on their website are either not up to date or purposely left incorrect. I purchased some PC100 SDRAM from them, which according to the website was in stock. They took my money and nothing ever came from it. Weeks later I tried to get an update VIA email, and even a phone call, and I was not able to get a hold of anyone. I was finally able to connect with someone on the website chat, they asked for me to send the order number. According to them, the order number didn't exist. I then forwarded the email purchase order I had. The person then said it was out of stock and that they would refund the money. When I asked for an ETA on the refund, they said paypal was having issues, that day and that I should see it in approximately two days. I never got a refund. They just shrugged me off. I had to open a case with Paypal to get a refund. After all this trouble, I finally got my money back. STAY AWAY from this website. It's a scam. read more

Having used DMS memory on several Apple Mac Pro (no, NOT MacBook Pros...Mac Pros!) for over 13 years, we've experienced memory failures far greater than Apple memory and a competitors' memory. For instance, the current memory failure we're experiencing is for one of our 2013 Mac Pros. This will make the 5th (3 within 2 months of each other) DMS memory module failure in less than 8 months, again, on one machine. When submitting the previous faulty memory for a warranty exchange, from the same 2013 Mac Pro, the entire communication process with DMS felt like an interrogation, even having submitted detailed information and the original invoice. While 6+ RAM module failures with 4 machines (the number of Mac Pros with DMS memory) over several years may not seem drastic, the downtime, work interruption and so forth (workflow interruptions, thorough testing/troubleshooting, removing/replacing RAM, submitting warranty claims and more), are costly both in productivity and revenue. Drastic nonetheless when compared to the aforementioned Apple and competitor's RAM reliability and functionality. Unfortunately, we cannot honestly recommend DMS RAM for Apple desktops for businesses. In fact we recommend (and have to our network support customers) avoiding DMS RAM, with respect to Apple desktops/workstations (we can't speak to reliability issues for Apple notebooks since those all have Apple RAM). While Apple retail customers (vs. business users) may not notice the loss of productivity, the aforementioned productivity interruptions can result (and have for us) costly work interruptions. In summary, recalling a quote we used with customers refusing to recognize quality (product, support, etc), ""The bitterness of poor quality remains long after the sweetness of low price is forgotten" - Benjamin Franklin read more

This is THE "go to" store in the huge internet shopping mall for RAM chips. Choosing the right doohickey for your PC / Laptop is confusing to most - like me - and I first used a computer in 1984. DMS customer service keeps bankers hours but provide patient guidance. Case in point, My PC performance improved dramatically. I added 12 GB at a price cheaper than Jeff's outlet (Amazon) but more importantly, DMS's impartial advice prevented me from plunking four hundred dollars on 64 GB chips that wouldn't do much. read more

I am a home computer user, not in any way a biggy. Over the years, since Mac OS was in single digits and not named after animals or geologic formations, I have a handful of times ordered memory upgrades from DMS. Small orders dollar-wise but big deals to me. The folks at DMS have always treated me with professionalism and courtesy. Emails have been answered in a timely manner and by someone who had actually read the email; phone conversations (1 or 2) have all been cordial, on-point, and helpful. Many years ago, I reported a problem with a recent order. A replacement was immediately sent, no condescension, no hassles, no waiting around for me to first send back the defective product. The replacement modules, btw, worked perfectly. Since that time I have only considered DMS for my memory upgrades, no shopping around. I still have the mouse pad that shipped with my initial purchase. My most recent order, again small peanuts, arrived way before expected. The only problems I had with this latest upgrade were of my own making. Once resolved after some hair-pulling and cursing, my mac booted and is running error free. DMS treats the little guy not like a little guy, provides a good product at a fair price, and is staffed by knowledgeable people who make people feel special. Try 'em; you'll not be disappointed . read more
