Hi r1co and Welcome to ROG 😄

Issues and relevant fixes associated with Qcode 55 are as follows:

Double check your DIMMs are the correct spec for the MB and that they are QVL qualified.
Run memtest86+ on each individual DIMM to eliminate that possible failure. Check for contaminated DIMM slots and use compressed air to clean.
Check your CPU mounting bracket fixtures as per this link: https://major.io/2014/08/22/asus-maximus-vi-gene-error-55/ and although a different MB, this might be worth a check.
Check your CPU mounting socket under a magnifier for any bent pins.
Should the issue prevail, then RMA the MB.

Hope this helps.

I managed to let it work by putting on BIOS to disable dimm slot 1 e 2 But why 😮

Hi r1co:confused: Do not disable any bios setting regarding DIMM slots.

It would be a good idea at this stage to fully list your system spec in your profile, List your DIMM specs CPU and PSU.
Which Bios version are you on?
Have you updated Bios or reset CMOS.?
Both the 4pin and 8pin connections are required for your system to boot. (as mentioned in your email) Depending on your PSU, both these cables should be supplied.

Hi MeanMachine And thank you for answer i Will update My system asap. Anyway My Psu miss The 8 Pin connector And only have The 4 ones. The bios is The Last one taken from Asus site i think is 3003... Anyway yesterday The PC boot up with 16 Gb of ram only by disabiling dimm slot 0 e 1... Strange But in this manner The ram is fully working, pushing The cmos result in Not reading again The ram And you need To set disable dimm again..

Hi r1co. Please refer to DIMM slots as A1, B1 (black slots) A2, B2 (red slots) for clarity.

I will wait for your full system spec as requested before further comment.
Depending on the DIMMs you are using, it is recommended to populate slots A2 and B2 with two Dimms.
Your DIMM slots have a one side clip and it is important to ensure the offside to the clip is pushed down and secure.

Your symptoms are unusual for me and either there is a problem with your Bios, the MB or incorrect DIMMs, as you should not have to disable in Bios as you describe.

I await your response to the questions asked.

Hi MeanMachine, I updated all my spec... the dimm slot that creates problem are : A1 ( black) and A2 (red)


Thx for you help :):):):):):)

Hi r1co :D. I cannot see any problems with your system spec.

Your Kingston Hyper x predator modules are rated to run at 2800MHz using 1.65v and fairly loose timings of 12-14-14-35.
The kit features a pair of XMP profiles and these values and voltage should be keyed in bios manually.
Your XMP profiles can be got from CPUz SPD in windows.

Good luck and I hope your problem is resolved soon.
