Hi guys, Not far ago I had nice suggestion about graphic cards on this forum and after that I like surfing here to try to learn more about hardwares. With newly bought mobo (Asrock Z68 Pro-3) , CPU (i5 2500k) and GPU (Asus Gtx560ti), I have started learning OC. I simply changed the CPU ratio from 33 to 40 in UEFI , enabled Internal PLL overvoltage and incease core current limit from 150 to 180. (actually I am not sure if it's neccessary, or matters) It runs stable, I guess. At least i played bf3 for hrs and nothing went wrong. The max CPU temp. raised from 73c with 3.3Ghz to 75/76c with 4Ghz. Anyway the question I want to ask is: Using CPU-Z, it shows the multiplier which I thought it is constant but it is actually floating, the minimum value is 16, and when it loads it raises to 40. I read some articles about OC and multiplier but I found no sentense saying it does float. hmm..it's normal... right?
