Vcore too High 2500K

post #1 of 5
Thread Starter 
Hey guys. Have a question. I'm new to overclocking and read the sticky on the following site regarding overclocking a 2500K. I followed all the instructions and set my CPU Manual Voltage to 1.35v and mutli to 45. When I boot to Windows (Windows 7 Pro x64), I run CoreTemp and HWMon and it shows my Vcore @ 1.4v. So I steadily decreased my VCore while testing in Prime 95 to 1.33v, but it still shows up at 1.38v. Even if I'm not running Prime 95, when I boot up my Vcore is at 1.38v. Also, because of this I believe my temps are too high. I was googling and just confused myself. I am trying to get my voltages to remain at what I set them to in the bios, it's off by .05 it seems but I'm not sure where to fix this.

Any help would be very appreciated. Thanks!

System Specs:

i5-2500K
Asus P8Z77 L-VK Motherboard
G. Skill Sniper RAM 1866MHz (I put in the correct speed and timing in BIOS)
Cooler Master V6 CPU Cooler (Ordered a CM 212 Evo which should be coming in today, V6 cooler sucks IMO)
Cooler Master Silent Pro 850W Bronze


Guide I followed:

This is normal so don't worry about it. Just focus on the Vcore displayed in CPU-z when running Prime 95. The Maximum Vcore displayed in HWmonitor is usually due to LLC overshooting during boot / light load conditions.

You should try switching over to offset w/ C1E & Speedstep enabled so the CPU frequency & voltage will scale with the load.

OK thanks. I'm going to run Prime 95 and have CPU-z running and check Vcore then. Ive been using CoreTemp and HWmonitor while running Prime 95 and both show the higher voltage.

Nothing to be worried about these cpu's will take 1.6v pretty well. Not that i would recommend using that kind of voltage but just so you know.

It is spike voltage on boot that usually kills cpu's.

Use CPU-z when stressing the CPU.

HWmonitor is fine for every day use after the system is stable since you will want to monitor more then just Vcore (Fan / Pump RPM, Tems, etc in one program). thumb.gif
