Kingston Technology HyperX Predator 8GB Kit (2x4GB) 2666MHz DDR3 CL11 DIMM Motherboard Memory XMP T2 Series KHX26C11T2K2/8X

There was several reviews that went away on amazon?? about this item.Is Kingston asking for fresh reviews as there were so many bad ones?Several ppl had posted negative review bcz this RAM will NOT run at 2666MHz.I thought that ppl had motherboards or bios that did not support this RAM or 2666MHz, so I bought it anyway, it was a good deal.I was wrong, this memory will not run at 2666MHz. I tried two different computers. I can run it lower at 1600 or 1800 and it works fine, anything over that, it either won't get past boot process or will have a system memory dump once windows is launched.This product worked for me and I get 8GB over 1800MHz. My motherboard is brand new and is capable of more than 2666MHz.Buy at your own risk!

Make sure your motherboard can take advantage of 2666KHz speed

Good memory. Awsome speed. .faster than ddr4 but uses up to 30 watts on heavy usace 2 modules

Very good ones, I used in an LG337 and works without fault for day one.

PNP with XMP Profile, Running CL 11 on 2666 is pretty tight.

excellent choice for i7 4790K

Works great.

I using the G.Skill RAM, But it was a little slow for me. Kingston is the cheapper than G.skill and performance is better than it.I'm very satisfying.
