XMP not working on z370 Pro4

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   My 2 x 8GB kit of Corsair Vengeance LPX DDR4-3200 CMK16GX4M2B3200C16 is on the QVL for the z370 Pro4, but my PC won't boot to Windows 10 with XMP Profile 1 for DDR4-3200. I enable it and the CMOS resets and the memory speeds default to DDR4-2133. I have updated to BIOS version 1.30, but the issue persists. I've reset the CMOS and set BIOS defaults and tried enabling XMP again, but still the issue persists. I have not overclocked the CPU or made any other changes other than trying to get the memory to run at its rated speeds.I have one module in DDR4_A1 and one module in DDR4_B1.

Any help is appreciated!

	I've just bought new set with Asrock z370 pro4 and Corsair Venegance LPX DDR4-3000 2x8GB and i have same issue. I cannot start computer with two RAM's inserted. Its booting after CMOS reset with one RAM. I did not try to update BIOS yet but i assume the result will be the same. I will try to check those two RAM sticks on different motherboard and i will also try different type of RAM on this motherboard (Asrock z370 pro4) but thats gonna take a while.

	Maybe you could try checking the voltages as per Flode's comments made for the Extreme 4 board: "vccio to 1.1V and vccsa to 1.15" http://forum.asrock.com/forum_posts.asp%3FTID=6860&title=z370-extreme4-xmp-bug
