Hey guys I just finished my first pc build and I'm trying to get the ddr4 ram to operate at 3200mhz. In the msi bios it seems like everything in OC is not available for tweaking even on expert mode.

The Z170 M says it is capable of handling 3200mhz and it's recognizing that I do have two 3200mhz corsair sticks in the dimm slots but it won't go past 2400mhz.

I have manually set up the voltage and settings which are shown directly on the ram. I have also enabled game boost and xmp. It has gone from stock 2133 to 2400 but that's it.

I can see there is some "memory try it" profiles that go up to 3200 but it's for Samsung micron and Hinix, there's nothing for corsair vengeance.

I can't tweak the DRAM frequency or adjusted DRAM frequency at all it's just grayed out even with the manually settings updated.

I have a i7 6700k so if I need to overclock I can.

Help is appreciated, thanks in advance!

It sounds like you have an error in BIOS. This can be cleared by doing a CMOS reset.

How to perform a CMOS reset, universal technique:
1) Turn the machine off and unplug it
2) Press and hold the power button for three seconds to drain all remaining power. Extend this time to five seconds for machines with power supplies above 1000 watts.
3) Open the tower, locate the CMOS battery on the motherboard and remove it. The CMOS battery is flat, it usually resembles a large watch battery.
4) Get a snack, take a nap, do whatever.
5) After at least five minutes have passed, put the battery back into the motherboard.
6) Boot into BIOS setup and set the date/time and any custom setting you may have had. Do not set overclock settings yet. Save your changes and exit BIOS setup.
7) If you wish to overclock, enter BIOS setup again and apply overclock settings.

1. Corsair doesn't "make memory"...hey buy it from Hynix or Samsung or sum1 else

2. Is RAM on QVL ?

For example... when DDR3 dropped, there was DDR3-2400 with 10-12-12-28 timings (Hynix) sold under the Mushkin Redline and Corsair Vengeance lines. The modules used here were made by Hynix who sourced all the higher speed models originally... later on, Corsair switched to a less expensive supplier for this model number. So if ya bought a set at build time and later were upgrading, chances were if ya bought the same model Vengeance, didn't match up so well with the original set as the new set was not Hynix and had slower timings. You could make it work but a Mushkin set matched up better.

Hey guys thanks for the replies, I also cleared the CMOS already today too, it still didn't work it won't go over 2400mhz.

I did try using one of the hinix profiles but the boot failed so I had to revert back to my other settings.

I figured it out, actually the issue was having game boost enabled. Game boost increases the CPU to 4.4ghz. So i turned that off and turned on XMP, that allowed the DRAM frequency option to be changed. So now my memory is running correctly at 3200mhz. I just went in to overclocking for now and 44 instead of Auto. so now I am overclocked to 4.4ghz without game boost.

So that is all set now, I can't overclock past 4.4ghz though my windows won't load properly if I try 4.6ghz.

Also, I am noticing my 1070GTX is operating at 4gb instead of 8gb. I think what is happening is the CPU integrated graphics are being used together with the GPU instead of just the GPU. I can see that the drivers for integrated graphics are included ahead of NVIDIA. If I go to Advanced and then to the integrated graphics option, I only have two options PEG and IGD, it is set to PEG which is for peripherals, but I don't understand why PCI isn't showing up.

@abice I think you're confusing the meaning of the word peripheral. If you look at the tower as a whole, things like Keyboards and mice would be peripherals but the video card would not since it's inside the tower. However, if you look at just the motherboard, the video card would be considered a peripheral because it's a device (separate from the board) that can be plugged in to provide functionality to the machine.

I agree with Tradesman1, PEG is the correct option for PCIe devices.

Something else is afoot here ....

1. Game Boost is a utility which simply loads a set of BIOS settings automatically ... it should not interfere with the boot process unless the settings it is picking aren't good enough for your build.

2. If you load XMP, it should automatically change the memory speed to the "advertised" speed.

3. Unless using the auto overclocking tool, your BIOS will need to have several entries changed as you increase CPU multiplier. The system may work with certain presets stored in the BIOS for lower multipliers, but the higher the multiplier, the more likely that the auto settings will be insufficient. One of the most important of these settings is Vcore.... the Vcore setting which the MoBo will select under "Auto" settings will in all likelihood be higher than what your CPU requires.

Every CPU is different and will require different voltages to run stable at any given CPU multiplier.... hence the term "silicon lottery" These settings are chosen such that the system will remain stable for 95%+ of CPUs. However,, again, in all likelihood, your CPU is outside that final 5% and therefore will remain stable work at a significantly lower setting. As the life or electronics is governed to a large extent by heat and voltage, it's really in your best interests to set that manually to maximize system life.

4. As you get in the 45, 46, 47 etc area, the less likely those auto setting will work. Again, those settings are chosen by the manufacturer so that a) they minimize tech support calls asking why OC won't work and b) that minimize the number of failures when peeps without the necessary knowledge and experience try and go to far and don't take heed of temp and voltage settings. 1.45 volts may be fine for a custom loop .... but not a 120mm CLC.

Wouldn't it be that I need to call MSI since that's the motherboard manufacturer??
Click to expand...

No. You need to get the correct settings input into the BIOS ... normally the MoBo reads this from the SPD and loads them onto the MoBo. It is the memory manufacturer who programs the SPD and they are the ones who are best suited to give you correct numbers for their product.
