ASUS CROSSHAIR X670E HERO QVL LIST

Why these rams are not listed in QVL?

Yesterday, I updated bios from 2704 to 2806, but today when i started PC but, then came bluescreen: phase1 verification error.

Hi @Jerska 

You need to verify stability, EXPO is classified as overclocking. Does the crashing desist at Optimised Defaults?

You can find more information in the articles below on how best to verify memory stability.

Hi @Silent_Scone ,thanks for fast support.

Bios settings are at optimised defaults and windows opened after couple of reboots. Now rams are under test (TestMem5) 1usmus v3 profile, but ram profiles are factory default = 2400CL40 with 1.1 voltage. So what I need to do next? I will run the test and left it running couple of hours.  2400CL40 1.1voltage finished without errors and then I tested 6200CL30 1.4V and vddio: 1.35. Test finished after 2h without errors. But if GDM off, system wont start and cmos needs clear.

GDM: Off tends to need more voltage. You may need to bump all or combination of, SOC/VDDP/VDDIO/VDD/VDDQ. My CPU didn't need bumps of voltage when I set GDM: Off.

Some CPUs don't seem to run GDM: Off from what I have seen. Maybe combination of HW in use and perhaps settings or the IMC just does not do it.

This ZIP contains some benchmarks with GDM: On and Off, you decide if it's that big a deal.

I installed bios again with flash utility at bios, but now bios wont reset itself and fans spinning very loud...C5 error code came twice....This mobo give me hard headache. Mobo is repaired one time, when they changed one conductor and now problems are back......Mobo worked many weeks without problems and tests completed without errors.....I hope that i could get refund!!!!

If you turn off power to power supply, do CMOS clear, turn on power supply and power up system it does not complete POST?

I had situation where my CMOS clear wasn't working as motherboard battery had lost some charge.

I turned off power from psu, CMOS cleaned, psu turned on and powered up system, but still uncompleted post twice in row......And then i did that same again and then system posted normally...I also thought that why system was stuck at C5 code and didnt reset itself? If bios and mobo works correctly, bios need to reset itself if stuck at C5 code and then automatically reboot and load with factory settings....
