So today I am offering a combo consisting of an GIGABYTE X79-UD5 LGA2011 motherboard and a 16GB (4x4GB) of G.SKill DDR3-1333 7-7-7 memory.
The X79-UD5 is essentially brand new. This is not the board I used for the review, it's a newer one with only about 4-5 hours on it. Basically, I flashed it to the latest bios, tested to ensure that all the doodads were working, and ran a few 3DMark and PCMark loops on it. All the accessories are included and they are sealed.
The 16GB of G.SKill DDR3-1333 7-7-7-21 1.5V memory is two identical 8GB kits. They work perfectly on this motherboard, and they are fully stable at DDR3-1600 9-9-9-24-1T (never tried higher) on this motherboard.
As I illustrated in the i7-3960X review you really don't need higher memory speeds. Aesthetically they are perfectly matched to the motherboard, so that's a bonus.
I'm looking for $300 + actual shipping.
If you have any questions feel free to ask
