I know that may seem a silly question, let me explain.


This week I build my first PC. As I started running stress tests to insure all was stable I became worried when my core temps began to get high (67C) under stress so I shut the test down after only a few minutes. I tried several different monitoring programs and they were all in unison. This is when I noticed my CPU Vcore was reading (1.51) higher then the manufacturers suggested max (1.4). I tried to lower this in the bios to 1.4 and my system would crash just after bios screen, so I set my bios back to auto adjust. I tried running another stress test and thats when I noticed my CPU was running at 3611.04 Mhz on all 3 cores and using 105 watts. This is 3.6+ GHz correct? My CPU is a Rana 445 which should have a stock speed of 3.1 GHz. So how did this happen? I have not changed but 2 things in my bios. First, I tried to unlock the 4th core which was partially successful but would cause my CPU to over heat so I went back in and disabled the core unlocking. The only other change I tried to make was lowering the Vcore to 1.4 which as I mentioned caused crashes.

I assume this is the cause of my high temps on a stock cooler. My questions are, how did it overclock? and how do I correct this? I am new to all of this and never looked at a bios untill this week. Could it be that the core unclocking changed settings that did not revert once it was turned off?

My system:

AMD Athlon II X3 445 Rana 3.1GHz Socket AM3 95W Triple-Core
Microsoft Windows 7 Home Premium 64-bit 1-Pack for System Builders - OEM
Antec EarthWatts EA650 650W Continuous Power ATX12V Ver.2.2 / EPS12V version 2.91 SLI Certified CrossFire Ready 80 PLUS Certified
ASUS M4A87TD/USB3 AM3 AMD 870 SATA 6Gb/s USB 3.0 AMD Motherboard
G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-4GBRL
GIGABYTE GV-R685D5-1GD Radeon HD 6850 1GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card

reset BIOS back to defaults maybe even clear BIOS and clear CMOS.
reboot and check settings after that.



That seems to have done the trick. Temps are much better at 59C under stress testing. Thank you for the help!
