Overlcocking the Intel 4770K (Haswell) on Intel DZ87KLT (Shark Bay)
Once again, we have a new platform release by Intel and a socket change that only accepts Haswell processors.
There is some learning curve involved to understand the new adjustment values in BIOS for overclocking.
The GPU, and memory settings are pretty much the same as what we have worked with on previous platforms. The Intel DZ87KLT-75K has improved bios function in terms of overclocking in BIOS more than ever before on previous launch releases.
The mounting for cooling has not changed and shares the LGA 1155/1156 mounting of 75mm hole spacing. Each board varies when it comes to the keep out zone around the processor. Most boards have tall capacitors in the keep out zone, some exceed the height of the CPU socket.
The Visual BIOS on the DZ87KLT-75K is much more responsive but the sliders are far too sensitive and require precise control to get the value you want. For some sliders this is an issue.
Temperature reading on die is limited to 0c and does not read sub zero.
The only major annoyance I found was the power management reducing machine speed during idle, this worked far too well and effected benchmarks as cores ramped up to speed, sometimes it would return to maximum non turbo ratio, sometimes it would drop down to 800Mhz. If the cores was not tapped long enough it would not reach max multiple speed rendering a lower score than if it were at max turbo multiple.
