Can i Use my Core i7-4930k with ddr4 memory sticks? I just understand that i bought ddr4 memory sticks ' with incompatible CPU What should i do?

Asami (08:57 AM, April 26, 2016)

Pretty much every test on x8 vs x16 has shown a max of like 2-3% e.g. negligible/margin of error performance difference, not to mention there's no practical use for more than 2 way SLi, at 3 and 4 way you're getting ridiculous diminishing returns.

pcie x8 will affect performance by 5-10%, depends on hardware, for exp: 4 of gtx980ti SLI

Asami (07:37 AM, April 16, 2016)

Which means literally nothing since no way in hell is any modern GPU going to saturate the PCI-Express Gen 3 bus even at x8.

The thing is 5820K only supports 2 way sli at x16 x8, or 3 way sli at x8 x8 x8 but 4930K supports 2 way sli at x16 x16, or 3 way sli at x16 x8 x8

impressive, but it only makes sense since the 4930k is $550 opposed to the 5820k which is $380
