Hello everyone!
I just finished building my new PC. I bought an i5 3570K cooled with a corsair h100i, Asus Maximus V formula, 16GB GSkill Ripjaws DDR3 (1333 MHz), Corsair Gold 850w PSU, GTX 690, and a NZXT Switch 810 to house it all.
I was planning on overclocking in the future, but decided that for now I would just see how everything ran at stock settings. Therefore I DID NOT ALTER ANYTHING IN THE BIOS!!! I REPEAT I CHANGED NOTHING IN THE BIOS!! I downloaded CPU-Z and ran it with and without prime95 and noticed something peculiar. Here is what it said:
Intel Core i5-3570K CPU @ 3.40GHz
Core Voltage: 1.336V (WHATTTT?!?!) this is at idle and stressed with prime 95
Clocks Core Speed: idle = 1600 MHz; prime95 blend = 4600 MHz (WHAT AGAIN!?!?!)
Multiplier: x16 @ idle and x46 with prime95
Bus speed: 100 MHz
I'm a noob at overclocking. I've never done it. I am slowly accruing more and more knowledge everyday so that I can overclock in the future. HOWEVER... even to my noob eyes this looks like and overclock to 4.6GHz!!! WHYYYY!!!! I didn't change anything in the BIOS.
After I saw this I went into the BIOS to investigate. Below is a list of everything I saw.
Synchronizing Target CPU- Turbo Mode Speed: 4600MHz
Target DRAM Speed: 1333 MHz
CPU level up: disabled
Ai overclock tuner: manual
BCLK/PEG Freq: 100.0
Turbo Ratio: Manual
Ratio Synchronizing control: Enabled
1-core ratio limit - 46
2-core ratio limit - 46
3-core ratio limit - 46
4-core ratio limit - 46
Internal PLL voltage: Auto
CPU Bus SpeedRAM speed ratio mode - auto
Memory Freq: auto
Xtreme Tweaking: Disabled
EPU power saving mode: Enabled
EPU setting: Auto
Intel Speed Step Tech: Enabled
CPU Ratio: auto
Turbo Mode: Enabled
Extreme OV- disabled
CPU voltage: 1.340V (manual mode) manual voltage: 1.330V
DRAM: kinda fluctuates around 1.5V (auto)
CPU PLL voltage: 1.819V (auto)
PCH voltage: 1.056V (auto)
Again my noob eyes tell me this is overclocked and overvolted. ADDITIONALLY I have experienced a couple BSOD upon stress testing with prime95 AND while in idle (browsing the internet). If this is an overclock, its obviously not stable.
Can someone please confirm if this is actually overclocked. Why would it automatically overclock when I didn't even tough the BIOS. I realize the ASUS Maximus V boards have an auto-OC feature but I am pretty sure you have to activate it yourself.
Would you recommend that I decrease the clocks to 4.4 or 4.5GHz and keep this voltage. Temps were around 70C during p95 and maxed at 74 on one of the cores. Or should I raise Vcore to make 4.6 stable. Or should I see if I can start from scratch. Do you think 1.336V is too high? I've seen some people achieve 4.5GHz while staying under 1.3xx V.
I'm sorry this is kind of a long post and there are a lot of questions I would like answered. In a nutshell: Is my CPU OC'd? If so, what would you recommend I do to make it stable (raise voltage or decrease clocks?)? Are voltages too high already? What would you change in my bios settings to optimize the OC?
Thank you all and any input will be greatly appreciated!
