CPU Vcore Offset - greyed out! - 4770k Gigabyte UD5H

post #1 of 4
Thread Starter 
I have overclocked my 4770k on my Gigabyte UD5h. Part of this process involved changing core voltage to 1.25v

Now, in CPU-Z, my core voltage is a constant 1.260v, i.e, it won't drop to 0.1v when I'm idling (like it did without overclocking)

Apparently, I can change this by increasing the 'CPU VCore offset' value... but it is greyed out

How can I fix this?

Thanks

Change voltage control to normal, then the offset should be accessible. It should be the first option, above offset.

Thanks mate. Setting 'cpu vcore' to normal (rather than 1.2v) does indeed make the offset menu appear

If I set it to the max (+0.400v), the low idle power state seems to work! I consume 0.132v on idle

However, 1 second of prime95 makes my temps reach 95C. Also, cpu-z says I'm giving the CPU 1.55v on load

If I set it to the min (-0.300v), it fails to boot

Any tips on what to do?

Thanks!

Update If I set it to +0.00v, everything seems to work brilliantly. Idles at 0.132v. Max temp 60C. Max voltage 1.16v. Is this the correct setting?

Sounds about right. When you slowly increase the offset, it adds to the stock voltage value.
For example, VID = 1.1v + Offset 0.020+ = 1.120v. Be careful with offset. It is very easy to push too much voltage through the CPU. In fact, offset can push too much voltage, so sometimes people need to use negative values on the offset to reduce voltage wink.gif
