HDD failure after Overclocking i5 -4690k for the first time.
I am new to overclocking and this is my first attempt.
Here are the settings I changed in bios (MSI Gaming Z97 5):
VCCIN Voltage: 1.7v
Ring Voltage: 1.1v
Core Ratio: 47
Ring Ratio: 35
EIST and Intel Turbo Boost: Enabled
CStates: Enabled, C7
Those are the only settings in my bios that I changed from default.
This overclock caused one of my HDD's to fail, I tried swapping the sata with another HDD and then that HDD started to fail. I asked around on reddit and someone told me I overclocked the PCI bus which was causing the SATA controller to crash. I don't think that is the case as according to CPU - Z my bus speed is 100 MHz and I did not touch the base clock in my bios settings, that remains at the default 100 MHz.
I stumbled upon this post: when googling the issue. I then came across this comment.
It's more likely that the higher voltages and frequencies are affecting the actual SATA controller, even Intel boards can suffer this problem.
So I then decided to try a spare SATA cable and connect it to a different port on the mobo, voila the HDD is no longer failing with the overclock active.
I want to see if anyone knows why the SATA controller is crashing, if there is a way to stop it, and if not is it okay to keep the overclock while using the SATA port that is working. I want to make sure I'm not damaging the mobo or something.
Thanks for any help '); }
