" rel="nofollow - hi everyone, i'm currently on bios version P2.80 with 2 x 8GB Gskill F3-1866C10-8GSR ram sticks. memtest reads and tested both sticks - 4 passes no errors when typing FREE cmd displays total 8071452 unraid server recognizes the 16gb installed, but it's only allocating only 8gb. that's my problem... - is this an issue with version p2.80 of the bios. should i downgrade to version p2.60 ? or upgrade to a new version as this has been detected by someone else? - is this an issue with the gskill sticks perhaps not compatible with this mb. hope someone can shed some light on this. thx |

" rel="nofollow - Make SURE they are in the correct slots. But, you have two Individually purchased sticks of mem vs a 16GB(2x8GB) matched Kit. Can I assume you just bought these two memory sticks? |

thank you wardog. no these are not new, we already on my server. only changes were bios update and unraid limetech upgrade, but didnt noticed this until recently. the old unraid dashboard didnt give this info, so i can't confirmed if this was happening before. they set up matching A1 and B1 slots. thx |

Hi, According the manual, if "you adopt DDR3 2000/1866/1800/1600 memory modules on this motherboard, it is recommended to install them on DDR3_A2 and DDR3_B2 slots" (white slot). |

hi nightbird. thanks for the reply. i just did what you suggested, memory allocated still shows 7GB but both bios and unraid dashboard recognized the other 8gb stick installed in the second white slot. i'm really not lucky, the only choice i think is left to do is to downgrade the bios. |

" rel="nofollow - hi sorry for the late reply. yes i have tried one stick at a time and booting all four different slots and it boots normally. we can see the memory in the motherboard bios setting and memtest no problem. unraid recognized it installed 8GB and allocated 7gb as soon as we add more memory, my unraid gui shows the installed memory going up, but the allocated stays at 7gb, it doesnt go up. i'm guessing, this is not hardware but perhaps the bios update that was done that is causing this issue. i'm not sure what else to do but to rollback the bios software to previous version, or can anyone help me with a setting i'm wrongfully doing? thx |

hi eveyrone, i was able to downgrade from p2.80 to p2.60 and i still have the same issue. next step i think is to get new memory sets... maybe one is really fried. thx

" rel="nofollow - one more thing, on the unraid forums, one of the users is suggesting to remove the type of memory sparing it has, by doing this, he said his issue went away. is there something in the asrock 970 extreme 4 bios to deactivate memory sparing? pls advise i can't find anything. |

hi everyone just wanted to close this post as i found the issue. the memory stick 2 x 8GB were not getting allocated properly when put on both white or both blue pair slots. i tried to put it one on white and one on blue slot, booting unraid and voila now shows 16GB installed and 15.946gb allocated hope this helps others with same problem. thx again
