Hey all, I decided I wanted to overclock my i7 to about 4.7Ghz as I've seen that it can usually deal fairly well with that Overclock, I have gone through some tutorials, even looked up a guide by Asus telling me what I need to do as well, however I'm not having the best of luck, First I'll tell you cooling feature, I have a H100i Watercooling unit on the processor, it runs a 100% load at about 70 degrees Celsius with the odd spike and such, for the Air flow management, I have a Storm Stryker FT Case, with the two fans on the drive bays and a third fan on the back of the case, (two 120mm on drive bays, 140mm on back) the Radiator with the two fans are on the celling of the case, The total air flow is good and the temperature inside the case is about 26-27 degrees celcius. The Motherboard is an Asus Sabertooth Z77. The UEFI Bios is good and is very informative with the overclocking possibility, however it doesn't work for me that well at all. I had to switch out my 750 PSU and put in a Non Modular Corsair 650 TX untill a new one is shipped out. (Don't know if that be the cause, For some reason I think it is.) My problem is that no matter how I fiddle and test out the the Frequency and the the voltage, I cannot get anything stable over 4.2 Ghz it seems, I did manage to get 4.7. however it is not stable at all and so is true with anything higher than 4.2 Ghz, and adjusting the voltage core above 1.350 seems to cut out the PC, I managed to get to 4.2 with Vcore at 1.275, The DDRM Frequency is at 1664Mhz, (Two Corsair vengence 8Gb 1600 Mhz ram) At the moment I am completely stumped, I don't want to go do more testing as I literally spent about 4 hours trying to sort this out and I am fearing for the CPU Health, From looking at most Guides, Especially the Asus Guide using the same Processor and a Maximus 5, and they all seem to be in accepting in that an frequencies of 4.7 and a Vcore of about 1.275-1.350, (1.275 Seems to be the most common). I was hoping someone could help me out, as I've lost count how many times I've seen that dreadful blue screen. PS, I will put up some Screenshots if need be, but currently cannot as I am out.
