6600k Help

post #1 of 3
Thread Starter 
I have my multi set to 45 and my offset set to +0.06. My cache speed is at stock. Under a P95 load, the Vcore sits between 1.236 and 1.260 and seems stable.

I then enabled my RAM's XMP profile which sets it to 3000Mhz. Got a boot error on first try, so I went into the BIOS and upped my VCCSA voltage by the smallest increment (from 0.95 to like 0.96v I think). It booted and passed a few minutes of OCCT memory stressing just fine.

But now I have a question about the voltages I am seeing in HWInfo64. I will just post a screenshot of it:



(This was taken during a Prime95 load)

As you can see, the Vcore looks good, but the VCCSA is at 1.296v. This is far above what it is set to in the BIOS. I assume the motherboard or the CPU has some sort of auto adaptive voltage thing going on, but I have no clue how to turn it off in the BIOS. I have checked all the settings and see nothing regarding adaptive VCCSA or DRAM voltages. There is one setting that says "voltage optimization" and I turned it off. Still it doesn't help. The VCSSA and DRAM voltages just do their own thing. My DRAM voltage is supposed to be at 1.35v under the XMP profile but it's up to 1.38v here. Again, what is causing this and how can I adjust these voltages manually and make them stick? My goal is to get a stable 4.5Ghz with as low of voltages as possible and with all power savings enabled.

Motherboard is Gigabyte Z170X Gaming 7.

Yeah i think the way gigabyte handles auto voltages for the SA is weird. Something to do with high memory clocks, xmp, combination of both or something. So I keep my both my IO and SA at manually at 1.2 just in case they don't over volt more than that. That way when I keep it at 1.2 Aida64 reads it around 1.16 around there.

Problem is it seems to ignore what I set it to in the BIOS.
