Hello all, 3 days ago my new GTX 1070 card arrived (KFA2 GTX 1070 OC Mini), so i remove my old GTX 670 and installed the new one without any issue.
Then i went into the bios to remove some extra info the card display at boot (like Nvidia bios version), but after the next boot the system hang and i get a message i never had before: Overclock failed, press F1 to enter the bios...

Is very odd, i don't have any overclock in my system, i run everything at stock minus the XMP profile.

Then i go into the bios and check the Ai Tweaker page and i find that the ram are forced down from 1600 mhz (XMP profile #1) to regular 1333. Is about 5 years i used 1600 profile.

From this point no matter what i tried to do, change profile manually, change voltage, remove the sticks and change slot, remove the cmos battery, boot with 1 stick, remove the graphic card and reinstall the old one, unplug all satas, usbs, change PSU, etc... there is no way they can work back to 1600 and if i force this setting, manually or through XMP, the pc don't boot, black screen with the RED ram led active.
Pressing memOK work but the system automatically find the DDR3-1333 setting as the only available.

Speaking with corsair support, they accept the RMA but i can't stay without pc for a month (i live in europe) and the price i have to pay to ship the rams is so high that at this point i'm probably forced to buy a new pair of rams and trash the old ones.

Of course if the issue are the ram and not something more dangerous like the slots or the VRM controller.

Memtest64+ also report no errors on the rams at 1333.

A week ago i also changed without any issue the original cpu cooler with a new one because the fan of the stock one was very loud (i bought an Alpine A11 rev2).

This is my actual system:

Cpu i7 2600K
Asus P8p67 rev 3.1
Vga KFA2/Galax GTX 1070 On Mini
Eam corsair Vengeance CMZ8GX3M2A1600C9R 2x4GB 1600 Mhz(XMP) 1.5v
PSU corsair TX750M

I take some screens:

As you see, the system detect through XMP the profile of the ram but when i save it the boot fail and back to 1333:

I hope my motherboard is not broken, i'm also a bit scary to buy new sticks because if the problem is the VRM or the slots i'm forced to change the whole system.

Thanks if someone can give me some tips to understand better what's going on.

Thanks for the reply, already tried this trick but no result, system hang with mem red led. I already tried so much combinations these last days, my conclusion is the ram can be broken.

At this point i think i will buy new rams to be really sure that the issue are the rams and not the mb and after RMA the Corsair ones.

I like these:

HyperX Fury, 16 Gb, no XMP, CL10, 1600, what do you think? I'm not sure however if i'm able to push to 1600 without XMP, but i read the specs and my mainboard is supported (P67 chipset).

If you have any more tips or better stick brand you can suggest me (need 2x8GB 1600 dual channel), will be very appreciated.

Conclusion: do you think my motherboard is broken?
