Crucial CT16G4RFD4213 16GB 288-Pin DDR4 2133 Server Memory

Pros: Works well, and packs a lot of storage into each slot. I ran MemTest86 for 30+ hours after installation with 0 errors reported.

Cons: None. I plan to double my system's RAM by summer's end, and will work my way up to the full 128G over time.

Overall Review: My system contains ASRock X99 Extreme4 LGA 2011-v3 Intel X99 SATA 6Gb/s USB 3.0 ATX Intel Motherboard Intel Xeon E5-2620 v3 Haswell 2.4 GHz 6 x 256KB L2 Cache 15MB L3 Cache LGA 2011-3 85W BX80644E52620V3 Server Processor SAMSUNG 850 EVO M.2 500GB SATA III 3-D Vertical Internal SSD Single Unit Version MZ-N5E500BW 2 x Crucial CT16G4RFD4213 16GB 288-Pin DDR4 2133 Server Memory (with more to come) I reused a case, a power supply, and some other odds and ends. It runs Ubuntu 16.04, and it is fast!

Pros: - Module came in protective casing - Received product as described

Cons: - Not compatible with ab350m chipset.

Pros: I purchased 2 of these to use in my Precision T7910 and they've worked fine for a year now.

Cons: When I bought them a year ago, they were nearly double the price they are now, but I guess that just happens with new technology (DDR4) over time.

Pros: Buy with confidence with these guys. First off, shipping was lightning fast. 3-4 days after receiving the package, I realized I ordered the wrong parts. I asked for RMA, got it the same day, returned the part the same day, got my money back 36 hours later. Tell me about a business that cares about their customer. Will definitively buy from them again.

Cons: None

Pros: package looks nice?

Cons: Don't tell me how, but I got two faulty sticks. Both faulted on a ASrock AB350 Pro4 and an MSI board. Tried one stick at a time, in the proper channels. No dice. Refund on its way. Major bummer.
