Voltage Problems

[Guest]

I'm having an issue with my piece of shit Gigabyte Z77X-D3H with voltages, I have manually set 1.165v yet it is fluctuating right the way up to 1.33v, it doesn't matter what I set in there it makes no difference.

 

I have disabled C1E, C3/C6, Thermal Monitor and EIST but even if I leave them on enabled or auto it makes no difference. I had this a while ago and clearing CMOS sorted it but now even that won't do anything.

 

Any ideas?

What do you have LLC set at.  Not sure of what the options are on that board, but with a high llc it will sometimes overvolt under load.  On gigabyte they are usually labled as normal, high and turbo.  Also what are you using to see the voltage?  some apps will show the wrong voltage.  Like for me core temp shows the voltage fluctuating at 1.09 to 1.2 no matter what I set it to, but cpu-z is usually pretty close to the actual voltage.  I have measured with a meter on the motherboard vs cpu-z and its within margin of error.

LLC is set at Medium and I am seeing the voltage in the BIOS and when in Windows HWMonitor, CPU-Z and AIDA64 are showing the same volts.

Mmmm well figured out the problem, I was looking around online and apparantly a previous voltage setting can stick so regardless of how many times you clear CMOS it has zero effect. So I reflashed the latest BIOS which for my board is F18i (fucking BETA) but with no joy the issue remained (anti-climatic I know :P) but turned out I had too little voltage when 1.165v was manually set.

 

I set it to 1.185v at 4.0GHz (shows as 1.176v in BIOS, HWMonitor and CPU-Z) and now it is locked with LLC set to high (not sure if that is too much or not), currently have AIDA64 running which I'll leave until I get home from work at around 10:30pm just to make sure it is stable but the thing I still don't get is that I am sure that I have 1.165v dialled in before and it ran at that.

 

Anyway thought I would update the post a little.
