Maximus IX Hero - Q-Code 55 again

Hi,

I, like many others, face the Q-Code 55 Problem on my IX Hero Board. I spent hours trying every suggestion here on the forum and elsewhere.

My memory kit is G.Skill Trident Z RGB 32GB (4x8) 3600Mhz CL16 and is also on the QVL.


Here is what I did:

- Reseat CPU and check for bent Pins
- Tried only two instead of four Dimms
- Raised Voltage to 1.38 / 1.40
- Tried with 2133 Mhz only
- Upped VCCIO and SA Voltage
- Cleared CMOS multiple times
- Checked memory on a ASUS Z370 and ASrock Z270 Board - all fine
- Flashed latest Bios (1301)

Sometimes the System Posts just fine (but crashes after a few hours). But most of the time the board gets stuck with Q-Code 55. Do you guys have any other ideas I could try?

Thanks in advance
Chris

If the memory is ok then the ram banks are the problem.
