That is odd, I would have thought that DDR3 1600 should be easy for the IMC even with an overclock. If you really want to see if your CPU can handle the XMP profile, put your CPU clock back to default and try XMP.

Technically without the overclock you already have, running the XMP profile is considered overclocking. Intel guarantees that the IMC (Integrated Memory Controller) will work at a particular JEDEC standard, and for your CPU that is DDR3 1600. It is a known fact that memory overclocking will negatively affect core overclocking and vica versa. In the case of Haswell / Devil's Canyon, and Skylake, you see very little performance benefits from running higher memory speeds. Well that is outside of a few RAM intensive programs and memory benchmarks. Every OC guide will tell you that you should attain the highest core OC and then attempt to increase RAM speed (which is presumably what you've done), but never sacrifice core clock speed for memory speed.

There are certain settings in your BIOS that can help stabilize your IMC. VTT, System Agent Voltage (VCCSA), and CPU IO Analog and Digital are the ones most associated with the IMC. In my experience VTT is one of the most common voltages that gets tweaked to stabilize higher memory speeds.

It might help if you told us what motherboard you have and what memory you have as well. Not just the speed of memory, but the actual kit you have.

What's your RAM memory sticks rated clock speed? And what did you manually set ram speed on the MOBO to? Try booting without XMP and that voltage/speed. Try turning on Load Line Calibration for a more stable Vcore, and maybe tweak total cpu voltage input to 1.17v+0,4v.-

Hi, i have a motherboard asrock z97 extreme 4 and ram corsair vengeance blue 1333MHz, (with xmp 1600Mhz 1,50v), but now i'm using standard clock for memory.

I own an Asrock Z97 too, and used a 4690k for a while also. I never went to tweaking memory, and I don't think its worth the stability loss for that little performance gain (nearly none). Rather push the 4690k further (it can handle for sure). Remember about LLC and chip voltage, since this mobo allows for very low vcore voltage because of those features, hence having lower temps.-

I ran a stable 4.4ghz with 1.165. Believe me, Asrock mothers manage low voltage for vcore with LLC on and chip voltage on offset mode with 0.4v+ over vcore.-

For now i have 4.40GHz core clock with 1.15+0.020V, cache clock 4.00GHz with 1.13+0.020V. Input Voltage 1.800, then LLC 1. How can I set the llc to level 2 in order to keep the voltages to 1.17 and 1.15?
