[SOLVED] Can't get memory speed over 2400mhz?

[JEZii]

Hey, I recently upgraded my CPU from i7-6700 to i7-7700K and now when I switch memory speed from BIOS with XMP to 3200, my pc won't start. It only lets me go up to 2400, and after that it won't start again. I've tried with different voltages as well but with no results. Also after this upgrade, my 2nd monitor won't open either. Tried it with a DVI to motherboard and DisplayPort to GPU.

May we have the make of your mobo, and have you performed a bios upddate for said mobo?

Ah yes i forgot. Motherboard is Asus Z170-A ATX LGA1151. I had to perform a BIOS update for it to work with the new CPU.

I would need the ram specs too, maybe for good measure, please list all your parts

Okay so, my pc in full:

CPU- i7-7700K
GPU: GTX 1070
Mobo: Asus Z170-A ATX LGA1151
RAM: Corsair Vengeance 16GB DDR4 3200MHz, 1.35V, Latency 16-18-18-36
Samsung SSD 860 QVO 1TB
Samsung SSD 850 EVO 250GB

Can you try the following:

have only one stick (ram) in your mobo, see if you can set xmp

try differnt slots (e.g. 2 and 4) for your ram and set xmp

do post your results

Tried, no result. Dont know why everything worked perfectly with the previous CPU.

i'm not sure what is causing the issue, so far it's either mobo or ram, is it possible for you to source other ram sticks? maybe a friend?

so you can test another kit on your mobo, this will save us a LOT of troubleshooting/guessing

Sure, i can test that later.

Pull up your motherboard manual and check which slots you should put just a single chip in. Set your bios to default.
Download and burn a usb stick with Memtest86
Boot to the usb stick with Memtest86 and allow it to run it's tests on that single stick.
Repeat for however many sticks you have. 1 at a time!

You are looking for errors. If you get none, continue, otherwise you have bad ram or mboard or cpu.

Yes, a bad CPU can cause memory to a) become damaged b)even with good ram a bad cpu can cause problems with memory. (I just had one a few months back)

Start w/ memtest

fyi: memtest is not a fast test. for reference, my 32GB modules in my kit took 9+ hours per stick to run.

Correct, this is why i would advise him to try a differnt (known to work) kit
