Bought four kits and they work like a charm. Easy installation and a quick upgrade. Huge value for the money spent. Speed, Stability and Memory capacity is perfect. Nothing on the outside of the computer tells how great it looks inside.

Initial review after 1 hour. Will update if anything changes.Bought A-Tech kit containing two 16GB 3200MHz ECC modules for Dell Precision 5820 workstation with Xeon W-2223 cpu. Existing ECC memory are two 8GB modules supplied by Dell: each 8GB module is a Micron part rated at 3200MHz but the 5820 runs them at 2666MHz system memory. The manual does not document mixing 8GB with 16GB modules but I wanted 48GB total. I kept the two 8GB in DIMM1 and DIMM2, and finally added the two 16GB in DIMM3 and DIMM4. The motherboard has the physical slots out of order with the DIMMx numbering so pay attention (initially I put the 16GB modules in DIMM5 and DIMM6 but my test application ran ~20% slower than final DIMM3 and DIMM4 locations). Make sure the side cover is back in place before booting the Dell 5820. The BIOS picked up the memory had changed and then booted into my OS. All good - Ubuntu 22.04 OS shows 48GB RAM available. Good product.

DIMMs are built with Samsung RAM chips, they are working properly, and no errors have been reported thus far. All DIMMs are identical. The items appear to be well-manufactured utilizing a high-quality pick-and-place line and oven.

Been looking to upgrade the 32gb in my Truenas Mini X+ which came with 16x2 GB of ECC RDIMMS. This 32x2 kit worked like a charm however of note the Mini X+ requires all ram sticks to be the same size so I had to stop using the original ram it came with. Not an issue with this kit as its super cheap for what its offering, might end up getting another soon to upgrade my system to 64gb

As described

i can't use this ram .. it doesnt work in a desktop .. so i needed to return it .. unopened and never used .. i started the return process and it asked if i wanted to print my own label or for a dollar i could have one sent to me .. my printer is broken so i chose to pay the dollar and have them send me the return label .. so far no label .. i even contacted atech directly by phone and told them this .. they said it was not their job to send the label and they don't even have a phone for amazon to call them .. so after spendin 2 hours with the automatic help thingy on amazon and gettin nowhere ( how many times can you say please send me a return label and have them not understand you ) to beggin them for a real person and they still did not understand that either ..so i got a number and called amazon .they said its atechs job to send the return label not theirs .. so as of now i still have no label and can't return this item .. i checked the correct box and contacted amazon twice and atech once .. this is totally unacceptable .. i might have to look for other places to shop online if this is gonna be so hard to return somethin . my very first return and all this ?? i'm not payin for this .. i need a return label .. thats all i want and it will come back unopened in the same package it was sent .. just gimme a label.. PLEASE .. PLEASE ..PLEASE ..

Arrived way ahead of schedule, and it's working great. You can see the difference in performance. Great for the price, I'm content and will buy again.
