Hello ,
I just bought a new system maximus x hero , 8700k, and Ram 3600 mhz g.skill trident z rgb and my pc dont want to boot in Bios. The board has the error code 55 and the dram led lighting is showing, from what i checked on board manual the 55 code is “ not ram installed” . I remove the ram and i put it again i switch position and i also try with one ram slot but nothing . Could it be a ram problem ? Can i have a little help or advice what the problem would be ?
Thanks

It was hard to close the mobo cpu socket . I will check when i will go home after work . Would it be also problem with bios ? To need an update for compatibility ?
Thanks

From a lot of testing i have some interesting results. I put the screws of the cpu block less tight and i reinstall the rams one by one and i manage to boot in bios .. The interesting thing is that the system boots only when i install the rams in the two last slot, right of the motherboard Dimm B1 and Dimm B2 . Base on the manual for dual channel it should be Dimm A2 and Dimm B2 .? Im a little confuse ,is it normal? I'm thinking that maybe i have to change some settings in bios for voltage for the other slots to work with the specific ram?
Thank you for your support

I check it , and i put the cpu headsink back i didnt find any bent pin either on board or cpu or ram. but why is work only on the Dimm B slots? Bdw i have enter windows and computer works normally . The computer not enter bios when only i install rams on ths DIMM A slots the first two ones.
Thanks

It looks like that there is a bent pin on the cpu socket , im not very sure if the motherboard came like this or i did it accidentally when i try to reinstall the cpu bracket, now what can i do ? :confused:

I bent it back somehow i manage to boot in Dimm A2 , B2 for dual channel but the B1 is not working now the A1 is fine. It would be a problem if i leave it like that ?
Thanks for your support.
