Hi, I have had my i5 4670K, Z87-HD3 PC since june 2013. At first I didn't overclock it, but I thought I'd have a go a few months ago. It used to turbo normally and idle at 800Mhz 0.8V then turbo to 3.8ghz at I think 1.1 something volts. I overclocked the turbo multiplier to 40 for each core, 1-core active, 2, 3, 4 etc. And I think I left the voltage on auto and I believe it then stays at 3990Mhz from then on and it doesn't downclock. For some reason my base clock is 99.75 Mhz. Now today I decided I would see if I can get any more Mhz, so I set the multiplier to 42 and voltage to 1.2V manual. It boots into windows and crashes within minutes with WHEA_UNCORRECTABLE_ERROR. I then tried to put it back to 40, Vcore still 1.2V and base clock manual to 100Mhz, but the BIOS froze when I saved. Now I have just loaded into the BIOS, the base clock is back to auto 99.75 so I left it, changed the ratio to 40, which I have been using for months.
The vcore is still 1.2v, so even when it's idle its at 3990Mhz, 1.2V. If I sometimes leave my PC on between 6-8 hours per day, is this killing my CPU? Should I try and get it to downvolt/downclock when idle?
Temps are ~35C idle, 60s in load at the moment. I would ideally like 4.2ghz or 4.4ghz, I was thinking about trying to raise the VCore to around 1.25-30 to achieve this.
What are your thoughts? If you need any more info, ask.
Thanks!
