5th Cores errors when stress testing an overclock?

My Setup:
MOBO: ASUS M4A89GTD-PRO/USB3
CPU: AMD Phenom II X6 1100T BLACK EDITION
FAN: Zalman CNPS9500A-LED
GRAPHICS: PNY Performance GeForce GTX275
MEMORY: Patriot Gamer 2 Series 4GB (2x2gb) PGD34G1333ELK (2 of these)
CASE: Antec DF-85 Full ATX Tower
OS: Windows 7 Ultimate 64bit

I am attempting to overclock my processor to a stable 4.0Ghz (I have heard that it can easily clock to 4.2) however I am having trouble passing a prime 95 test.

When I run the Prime test my 5th core encounters an error within a few seconds (this does not happen when stress testing at stock speeds).

Overclock Settings:
CPU Multiplier: 20 (stock is 16.5)
Offset Voltage: 1.344
Offset Voltage Multiplier: +.07000

I was using this guide.


To stop the core errors should I continue to raise the offset voltage multiplier?

Reading other threads with offset voltage confuses me when they only use multipliers of +.02 to achieve a stable overclock.


Thank you for your help!
 
Solution
It means you need to raise the voltage, one way or another. And every chip is different. Each one will need a different voltage to run at different clocks.

Should i just keep increasing the offset voltage multiplier?

Or should I switch to manual voltage? I've heard that its better to stick with offset but the voltage parameters in the BIOS for it are confusing to me.
