Computer Upgrades Part 1

Life After the Honeymoon This is the first of my entries into what it has been like living and working with the computer I built back in January 2014. For the most part everything has been working normally and without any major trouble. The initial round of discoveries through ownership I made related to how the pairing of Intel Core i7-3770K – Ivy Bridge CPU with the z68 chipset. While both are 1155 socket products they do have their hardware preferences. To that end the 3770K can only reach a clock multiplier of 39 on a z68 chipset, meaning that it cannot clock over 3.9 GHz. This in itself defeats the reason for owning an unlocked and overclockable CPU. At any rate I wasn’t too bothered about this since the CPU was still a solid performer. Superior Firewire I began to noticed that kernel_task in OS X was using a unusually high amount of CPU cycles at idle, 10% of one of eigth threads. Since Firewire busses are dependent on the CPU for processing this usage is reflected through kernel_task. I double checked of the same card with my 2010 Macbook Pro and saw that it was running at 5% on a slower four thread dual core system. In both tests I checked by having my Focusrite audio interface on or off. After further research I pinned it to the integrated Firewire controller on the motherboard and its behaviour in OS X’s Console logs. It was displaying an invalid GUID which would continue flagging during system uptime. This does have the knock on effect of affecting stability and increases...
