4670k bottleneck

When you are trying to overclock the cpu are you increasing vcore manually or leaving it on auto? If leaving it on auto that is likely to be the problem because a 4670k should be capable of more than 4ghz. My old 4670k did 4.4Ghz (core and cache) in my old Asus Z87 Hero and it does the same 4.4Ghz with exactly the same settings in my wifes Gigabyte B85M-D3H. It needed 1.275v vcore, LLC set to 4, CPU Input voltage set to 1.90v (wouldn't go past 4Ghz with less), cpu multiplier set to Sync All Cores, max multiplier 44x, min multiplier 8x, and 1.300v cache voltage (ring voltage on Gigabyte) for overclocking the cache to 44x. You may need up to 1.35v for vcore, it depends on the chip.
