Original Listing...
This offering is for new OLOy "OWL" 2x8 GB (16 GB) memory modules. Aesthetically, these modules are not too bad in that the heatsinks are all black in color. Functionally, I've had good luck with this memory in many builds (mostly Ryzen) over the years. They are DDR4 (Double Date Rate - Type 4) SDRAM (Synchronous Dynamic Random-Access Memory) running at 3000 MT/s or MegaTransfers/second. This is not to be confused with the true clock speed of 1500 MHz x 2 (because DDR memory performs two operations per cycle). Said another way, MT/s is sometimes labeled as effective MHz, which is why we also see the clock speed of 3000 MT/s referred to as 3000 MHz. Then there is memory timing...measured as 16-20-20 for this particular memory module. These numbers generally describe latency, which is the amount of time between memory operations (including the amount of time it takes for memory to respond to a data request). So in summary, higher clock speed numbers are better (because this tells us how much data our memory can move...send/receive...per second), while lower timing/latency numbers are better (because this generally measures the delay between memory operations).

I also want to confirm this is a DIMM (Dual-Inline Memory Module) with 288 pins that is intended for a desktop computer. For those that are interested, you may also see this memory labeled as: "PC4-24000".  This labeling indicates this module is unbuffered (or non-registered) and has a memory bandwidth of 24.0 GB/s (or 24000 MB/s). Please note the bandwidth (24000 MB/s) should not to be confused with the transfer rate (3000 MT/s). At the risk of getting too far into the "weeds", all personal (x86) computers use a 64-bit (wide) memory channel. When this channel includes DDR4 memory running at 3000 MT/s, the bandwidth of 24000 MB/s may be computed as follows: 3000 MT/s * 64-bit channel * 1 byte / 8 bits = 24000 MB/s. Lastly, the PC4 part of this labeling is similar to the DDR4 labeling above. In other words, this labeling is an indicator of Type 4 memory running at a fairly standard voltage for Type 4 DIMMs (so this memory runs at 1.35 V). 

The history of this memory is that I buy new packages of memory in small lots when pricing makes sense (because I know I will eventually use it in computer builds). Although, occasionally, I will offer some new memory for sale because I simply have too much on the shelf (and that is the case here). I also want to confirm this memory is still new and sealed in its original shrink wrapped packaging.

Note to international customers regarding customs...
We also apologize to those that feel their country import taxes, duties and brokerage fees are excessive. As a small US business, we are required by customs' laws to declare each order as a retail sale. Additionally, the declared order value must be equal to total store purchases and/or winning auction bids (less any shipping costs, as these are not considered in the declared value). As a result, each customer will be responsible for paying his/her own country taxes, duties and brokerage fees, which will be collected upon delivery. Again, we apologize for these additional costs, but we cannot afford the penalties and fines that come with breaking customs' laws...so we have to strictly abide by them.
