So, after tons of reading and watching many videos, i was able to get my 5.0ghz OC stable on my gigabyte board stable at 1.37v, and LKLc set to turbo. This seems alarmingly high, seeing others have 1.28-1.33v with a 5ghz oc. No one i have seen has had to set so high. I know it's a lottery, but should i worry with this much volatge? I was able to get 5.3 stable at 1.395v, and 4.9 stable at 1.35v. I dont have to have a 5ghz OC as i dont play many demanding games lately/at the moment, but i wanted to see what it would take. Cinbench ran 1581 multi core and single 215 at the 5ghz OC Which went up 12, and 5 respectavily from the 4.9ghz i ran. I think im going to delid, current idle temps at 5ghz are 40-42c but my cpu temps are wonly at idle. I will run some firestrike then some mor etaxing benches to make sure of this.

Is this voltage what you entered into the BIOS? Or is it a reading of vcore when CPU is under stress test?

 

Is LLC turned on?
