TURBO CORE = 1.425v
turn it off

Turn off APM and Turn on HPC
also setup in control pannel high performance power profile (under power options)

turn off any gigabyte power managmenet utilities (Asus calls it EPU i dont know gigabyte version of it but i assume they must have it as well)

overclock manually to 4.2ghz

probably will work @1.35v

that's not your stock voltage, that's your turbo core voltage.

You Cpu is likely throttle due to these possibilities

1.Your VRM temperatures are to high (most likely)
2. APM is being tripped (exceeding 125watt tdp)(common)
3. Its not throttling, the program which you use to determine its throttling has issues.

First if you have a UD3 Revision 3.0, I am sorry. They have issues. If you have any other revision other than 3.0, you should be fine.

For more information head over to the AM3+ Gigabyte motherboard owners club.

Well I have a revision 1.0 UD3 and an 1100T CPU. My BIOS ALSO sets 1.425vcore as default (I believe this is to accomodate the 3700mhz turbo speed without voltage issues)

I've found, however, that running stock clocks @ 3300mhz I can easily get away with AS LOW AS 1.325Vcore and have had never had a problem.
