Let me explain.
I have one ITX Z68 Motherboard for the Ivy Bridge, up to i7-3770k by BIOS support. But I have a i7-3770T(45 Watt TDP BS) at home in there;
With that and my motherboard, I can do 4,1GHz on the non-k OC ITX motherboard and 2x4GB 2266Ghz OC. Who would you think would against, 3000Mhz 17-20-20-X, CPU at 3.0Ghz, Equal.; 8600k.
Tested with a 1080
No winner, marketing
Conclusion Rock, if that is on XMP 1,35v, at 3000, you got fooled. Unless the price was ok (65 pounds for 2x16GB at 1,2v! at 3000Mhz?) second handed market. 9700k is 250 euro's 4x8GB at 2800 1.2v is 60 euro's. Professorial build are, they need profit.
