## Description

Brand: SamsungPart Number: M386A4G40DM0-CPB Memory Type: DDR4Memory Size: Single 32 GB Module Form Factor: DIMM ( 288 Pin ) ECC Type: ECC-LRDIMM ( Load Reduced DIMM ) Speed: 2133 MHz ( PC4-17000 / PC4-2133P ) Rank: 4Rx4 - Quad Rank x4 Voltage: 1.2VThis memory is ECC Load Reduced and cannot be mixed with different ECC types such as ECC Registered, ECC Unbuffered, or Non-ECC Unbuffered; (Memory compatibility can vary among different system models and their installed components; please verify compatibility and follow memory channel guidelines to ensure maximum performance)

Review: Very stable RAM. - I have bought 16 of these. First off, verify you need ecc ram. These will not work in your consumer desktops. Second when you are installing make sure you have clean pins "blow out the slots". Third fully seat the ram evenly. Fourth make sure you give your desktop ample time to boot/configure the new ram. My P920 took about 30 minutes of a blank screen to do its checks. Over all all 16 have worked flawlessly. 8 of them have been loaded to 98-100 percent for 6 months without faulting. Definitely a good buy. Very reasonable price. Just make sure you need ecc ram. If you question it check your old ddr4, non ecc has a even number of chips in. Ecc will have a odd number off chips. As ecc is buffered.
Review: cheap ram, works good, no complaints - Works good in my system

### ⭐⭐⭐⭐⭐ Worked great in my Dell Precision Workstation
*by G***T on December 3, 2023*

The DRAM dropped in and ran perfectly in a Dell Precision T7910 with a Xeon E5-2620 V4 Processor. It's a single processor system. I've been using it for a application that runs 24 hours a day. The DRAM has had no issues.
