System Information:
CPU: I5 6600K
GPU: GIGABYTE 1070 8GB
RAM: 2X16 GB VENGEANCE LPX Corsair 3200 Mhz
Motherboard: Z170 PC MATE
BIOS VERSION: EZ971IMS.A40
BIOS Build Date: 09/07/2015

So, I recently bought this kit of ram, and I've been trying to run it at 3200 Mhz by enabling xmp but I won't boot , so I decided to set up manually the voltage and everything that corsair in their manual says. So, is there another way to solve this problem? I have read that I can update my bios , but technical support suggested me that maybe it won't work because the MB is too old. Thanks for the answers.

That's indeed an old BIOS, I would try updating BIOS, because it improves RAM compatibility and if you look at the changelog it also has some system security vulnerability patch.
Even in the end RAM still not work at 3200MHz, I'm still happy that system becomes more secured.

another thing is that is a 1st gen DDR 4 Design of memory controller and intel only have rated it at DDR4-1866/2133 so 3200Mhz would be at least a 50% Overclock as it compared to the 2133Mhz intel rates it at would be 150.02% the speed and that is asking for alot. you would have to increase the Memory controller voltage quite a bit and hope it can do it to get the speed your after if the BIOS update Fate suggested doesn't help to even have a chance of pulling that off.

DDR4-3200 isn't out of reach on Z170 and 6600K, here's from an older system of mine,

3200.png


This is a Kingston kit that only uses 1.2V XMP voltage to reach DDR4-3200. Other kits more commonly need 1.35V XMP. But even at 1.2V and relatively low IMC-related voltages (or even stock ones), it's not uncommon to use this on that platform.

As has been said, definitely update the BIOS (first, for the 1070, check if it needs this update: https://www.nvidia.com/en-us/drivers/nv-uefi-update-x64/ ).

BIOS Update how-to:
1) Get the latest BIOS. It's the topmost one on the MSI support page for your board: https://www.msi.com/Motherboard/Z170A-PC-MATE/support
2) Extract the file and you will get a text file and the BIOS file. Put the BIOS file into the root folder of a USB stick/drive.
3) Enter the BIOS by pressing DEL during boot, go to "M-FLASH" in the BIOS.
4) Once M-Flash (the updater) is loaded, it will show a list of your drives. Select the USB stick and select the previously extracted BIOS file on there.
5) It will ask for confirmation and then update the BIOS. It's fully automatic from there, takes about two minutes.

You are three years behind the newest one with your BIOS version, so yeah, it can make a lot of difference.

Hey, I tried what everyone recommend me, so I updated my bios and I tested the following:
1. XMP ON -> Won't boot
2. Voltage 1.25V , DDRM to 3200 MHz -> Won't boot
3. Voltage 1.35V , DDRM to 3200 MHz -> Won't boot
4.Voltage 1.35v, DDRM to 3066 MHz -> Boot succesfully
5.Voltage 1.135v, DDRM TO 3100MHz -> Won't boot

So it looks like it can't manage the 3200 MHz at all.

Can you make a screenshot of all the voltages in the BIOS, under OC? Could have to do with the IMC-related voltages.
Press F12 to make a BMP screenshot to a FAT32 drive, then convert to PNG or JPG for size and upload here.
