XMP enabled on Gigabyte Gaming 7 overclocks CPU


I just got my new PC running with the Gigabyte Z170x Gaming 7 motherboard and Intel Skylake 6700k. My memory is Corsair Vengeance LPX and it's base speed is 1633. With XMP enabled it runs at 2400.

So once I got everything installed and running I went back into my UEFI BIOS and enabled XMP to profile 1 (the only option) and the memory now runs at 2400 as expected. However, now the CPU is automatically bumped up to 4.2GHz instead of the stock 4.0GHz. If I disable XMP the overclock remains at 4.2 even though XMP is disabled and the memory is back to 1633. I wanted to run XMP but I didn't think it would force a CPU overclock also.

I found this on another site about this issue:

"The most troublesome "feature" of the firmware is that if you enable an XMP profile or change the memory multiplier, the CPU is automagically overclocked by applying the highest turbo multiplier—normally only used if one core is busy—to all turbo states, no matter how many cores are active. For a Core i7-6700K, this tweak means that if more than one core is active, you'll be running at 4.2GHz rather than 4.0GHz. A lot of modern boards play games like these with multipliers, but what makes the Gaming 7's behavior particularly nefarious is that the firmware shows the default non-overclocked Turbo multipliers while actually using the overclocked ones. To make matters worse, there's no single config option, say "Enhanced Turbo," that disables this behavior. Instead, you have to set the four turbo multipliers to their proper values of 42, 40, 40, and 40 manually. Nasty."

So I have no experience with overclocking. Is this bad? I just wanted the memory to run a bit faster at 2400 since that's what the box listed it as being capable of. Should I be worrying that the CPU is overclocked like this automatically? Is this normal? What else has changed in the BIOS after enabling XMP? I want all the cores enabled and I want turbo enabled also. What do I set to bump it back to stock 4.0GHz if I want to? Even in Gigabyte's EasyTune software, it now lists the default as 4.2GHz.

 

the CSM option in bios is disabled -how do i enable it?

tried to unzip..cant do it.. i got the file straight from linux site. why does it say password

 

BSOD when XMP Is Enabled

Though enabling XMP may be considered an "overclock", bear in mind the memory you bought was designed to run at 3200MHz, not 2133, therefor by that definition, the memory is running "below" its stock speeds.

That said, you could "manually" push the ram up to it's rated speed of 3200MHz, timings and voltage without using XMP.

I'm not trying to dismiss the help and suggestions here, if you have BSOD's this is the place to be. However, your issues are RAM centric, and that's where you need to look. In choosing to go to a different BIOS you seemed to have solved the issue. I'm thus saying let that issue play out before confounding things with other stuff that may not be necessary.

Also realize XMP is actually designed to get the RAM to run at its rated speed as opposed to the industry JEDEC specification set at 2133. Yes, you could run at 2133, but this is not going to tell you if the memory is problematic running in it's designed XMP mode. And again, you can manually set without using XMP, though XMP would be doing the same thing wile taking the guesswork out.

Anyway as I said, that site is the best place to look since they specialize in your board so they should have an answer to your RAM questions. For BSOD's this is the place to be.

My two cents.

What is XMP - What are XMP profiles and how do I use them?
