I have a Gigabyte Z87X-D3H MB, i5 4670K and 8GB of Kingston HyperX Blu ram at XMP 1.3 1600 and I run my 4670k at 4.2Ghz it's a very low OC but I only need 1.128 Vcore and at 4.4Ghz I need 1.152 but since I don't need the 4.4Ghz OC I figure I will stick with 4.2Ghz for now and if I do need another 2Ghz I will go back to it. I am finally learning all the new UEFI bios stuff and since I was never a big overclocker I only new how to OC my Core2Quad. But now with all of this CPU Ring/Vring,ect,ect and so on.. I am now picking up on. It is pretty easy. I was wondering one thing though, is it ok to turn off Turbo Boost and just OC to 4.2Ghz that is what I have done. I have left all of the other Power Saving options on. I just have Turbo Boost off. What do you guy's think? Also I have been running Intel Burn (It make's my CPU the hottest out of all of the test's... With Prime I go up to about 76 top's. I just really want to know how long I need to run these burn tests every time I OC or change something? I feel that 20min's of running the test is more then enough myself but I am told overnight,ect. But I would rather have my CPU run that hot for the least amount of time. I alway's run Intel Burn first then Prime since I have seen Intel burn tests pass but prime will find an error and that is always within the first few minutes of the test. As I am writing this I am running prime as I just lowered my vcore when I brought my CPU back down to 4.2Ghz and it's been about half an hour now..
