AMD Athlon II X4 630 running at 1.568V?

Hey guys,
I'm getting a 1.568V core voltage on my processor looking at it through CPU-Z. It's supposed to be 1.4V stock. I've only upped the bus speed to 210MHz from 200MHz as far as over clocking goes. I can't figure out why it's so high. That can't be a healthy voltage.

Edit: I restored it to no overclocking and I'm getting 1.576V core voltage now... Even higher!

CPU-Z has been known to give false voltage readings. You can go into your bios and and see what your motherboard is reading as your voltage. It should be noted that CPU-Z isn't normally off by that much, so maybe you should remove CPU-Z completely and re-install and see if your getting the same readings.

Set your Bios to default and check again.

I did both of your guys' suggestions and I'm still getting 1.575V.

There is no where in my BIOS to change the CPU voltage.

Seems strange that you wouldn't have an area to change the voltage. Which mother board do you have?

This is my system:

My system:
ECS BLACK SERIES GF8200A (V1.0) AM2+/AM3 NVIDIA GeForce 8200 HDMI ATX AMD Motherboard
XFX HD-485X-ZDFC Radeon HD 4850 1GB 256-bit GDDR3 PCI Express 2.0 x16 OCZ StealthXStream OCZ700SXS 700W ATX12V / EPS12V Power Supply
AMD Athlon II X4 630 Propus 2.8GHz Socket AM3 95W Quad-Core Processor ADX630WFGIBOX
Patriot Viper II 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Desktop Memory
Seagate Barracuda 7200.12 ST3500418AS 500GB 7200 RPM SATA 3.0Gb/s
Cooler Master Hyper 212 Plus CPU fan


I've found a lot of my CPU overclocking/settings are locked because I have a 630 Propus and not a black edition processor.

Also, in my BIOS it says it's running at 1.408V. But still, thats a huge read difference from CPUZ. Should I still be concerned?

I used to have the exact motherboard & I never encountered this problem. I was even able to overclock my PII X3 720BE up to 3.4GHz with & able to manage the voltage well.

Because you are already using an AM3 processor I assume you have already updated your BIOS.
Even 1.408V at default setting is high.
Is the "Cool & Quiet" feature enabled in BIOS too?

You had a lot more options in the BIOS because your CPU was a "BE." Mine is not, and therefore I don't get to control voltages.

All I have in the BIOS is the Memory voltage, HT voltage, NB voltage, CPU Mhz. Nothing for CPU voltage.

I believe Cool & Quiet is enabled, yes.

If you change your CPU settings from "auto" to "manual" in your bios that should allow you to adjust all settings. I've overclock non-black edition CPUs' in the past.

Looks like some problem in the Vcore reading then. What about your temperatures? If your processor temperature is within normal operating range and you don't experience any problem with stability, then I guess you have less to worry about.

Rage, I don't have that option on my mobo. I just looked again.

Randomkid, I feel like you're right. I don't think CPUZ is reading it right. My temp right now is at 22*C. I've got a brand new cooler on it, and it's overclocked to ~3ghz right now. If I bump up the Mhz to get to about 3.3ghz, I've had some crashes under stress testing, but I'm not sure why.

Just try to lower the overclock a bit, say 3.2Ghz & see if it will stabilize. It will be nice if you got it stable at 3.2Ghz given that you do not have the ability to adjust voltage in your mobo.
