To start, this set is so rare in fact eBay does not have the stock image of this memory, so I've provided multiple and information on the boxes for future listings. 

This is an incredibly rare matched set of Corsair Vengeance LPX 32GB matched memory kit, 2 × 16GB, DDR4 3000MHz, CL15, red heat spreaders, model CMK32GX4M2B3000C15R. Pulled from a working desktop and handled carefully. There were purchased from new, installed once, and removed one. Includes both matching modules. This is desktop DDR4 memory, not laptop SODIMM, and it is not ECC/server memory. Please confirm motherboard compatibility before purchase. 

Tested working before listing. XMP profile recognized at DDR4-3000. With tweaking in the BIOS, these can be run at MUCH higher speeds. 

Corsair hand picked the chips on these and they are low latency and fast! The boards these are built on are unique in that Corsair beveled the bottoms to shorten traces and decrease latency. Clever!
