Don't know how long this has been going on but I'm guessing it happened after I updated my bios. I have 16gb ram installed, bios and windows only show 8gb it used to show all 16 but now it does not. All 16gb show up in CPU-Z but no where else. I have tried all 4 sticks in different slots and different configurations and all slots work and all sticks work just not all together. My set up is: MB: ASRock P67 Extreme 6 Bios: P2.10 Windows 10 home 64bit CPU: i7 2600k Ram: G.Skill PC3-12800 4 sticks at 4gb each Like I said it has worked in the past but was having some other issues so I updated my Bios about a month ago and not sure if thats when it stopped recognizing it or if it stopped before that. *Also posted on Tom's Hardware

Not knowing when the missing memory situation happened makes it more difficult to diagnose, of course. Two things catch my attention as potential causes, or are related to your situation: Updating the UEFI/BIOS. UEFI 2.10 is the Ivy Bridge processor compatibility update, any you have a Sandy Bridge CPU. It's not wrong to use 2.10 with your CPU, but as the warning in that update say, you must at least update the Intel Management Engine (IME) software. Did you do that? That is also related to the next thing, below. Using Windows 10. When did you start using Windows 10? Is your Windows 10 installation an update, or a fresh, new Win 10 installation? Whether an update of new installation, you should download and install the INF driver ver:10.1.1.8, and Intel Management Engine driver ver:11.0.0.1156, installation programs from your board's download page (the forum's link creation tool is having issues, I can only link to your board's main page): http://www.asrock.com/mb/Intel/P67%20Extreme6/" rel="nofollow - http://www.asrock.com/mb/Intel/P67%20Extreme6/ Missing memory, less being recognized than installed, can be caused by the memory speed being to high, and/or the DRAM voltage being to low. First try to simply get all your memory recognized. If you are using the XMP profile now, disable it and set the memory speed to Auto, as well as all the memory latency and other memory settings. We don't know what DRAM voltage setting you are using, at first try Auto. If that does not work, try increasing it by 0.5V. Sometimes the voltage setting and the actual, resulting voltage can be different. If your H/W Monitor screen does not show the DRAM voltage, find another program that does, as CPU-Z or HWiNFO64. If you can get all your memory recognized, then try using the XMP profile, or increasing the speed and latency options manually. Do changes in small steps, and save working changes in a profile in the UEFI. The VCCSA and VTT voltages can also help with memory, small increases are usually the most that is needed. Your board also has a Beta UEFI version, L2.19, that improves memory compatibility. That UEFI may have fixes that will help with your memory issue. The time of the last UEFI update and the start of using Windows 10, we don't know, but clearing the UEFI/CMOS with Windows 10 installed, is a good idea. Windows 10 slips in updates all the time, and who knows what affect they have. Your P67 system is on the border line between good Win 10 compatibility with newer systems, and questionable or less than optimal compatibility for earlier systems. The further back in time we go from Sandy Bridge chipset boards (yours), the more compatibility issues we see with Win 10. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Yes I have updated all my Intel drivers. My memory all shows up in CPU-Z so it's not missing but it does not show up anywhere else (bios,system) when I go into my BIOS I don't even have the XMP option, I have tried both the BIOS 2.10 and BIOS 2.19 XMP does not show up in either BIOS, is there anywhere I can get the old BIOS from and use that, I know that one works because my memory used to all show up.

What "old' BIOS, and I'll post a link to it here as soon as I get a response. |

I'm not sure I guess the one right before 2.10 or one that is compatible with sandy bridge for the p67 extreme 6. Thank you

I don't see a 2.00 or 1.90 Below is the Instant Flash ver. of 1.80 http://www30.zippyshare.com/v/Y9lny9dY/file.html" rel="nofollow - http://www30.zippyshare.com/v/Y9lny9dY/file.html Below is the Instant Flash ver. of 1.70 http://www30.zippyshare.com/v/cYA6dXit/file.html" rel="nofollow - http://www30.zippyshare.com/v/cYA6dXit/file.html |

| " rel="nofollow - Thanks for the reply, sorry its been so long I was going to build a new computer around the holidays so I didn't mess with the bios you gave me I was just living with the 8gb of ram but now I tried to update my bios and can't get the files to be recognized in instant flash, is there something special I need to do? I have tried 2 different usb sticks both reformatted in fat and fat32, when I go to instant flash it can not find any files. The 1.70 shows up as a 70 file and the 1.80 as an 80 file under win explorer. Do I just copy that file to the usb and nothing else? Thanks |

" rel="nofollow - Yea, unpack the file. Then move it to the root of a formatted FAT32 USB stick, inserted into a USB 2.0 port at the back of the computer at the rear I/O panel. That help? |

No, sorry. What size thumb drives are you using? Too, a fresh FAT32 format sometimes helps, as does 8-16GB sized thumb drives. And no  I don't have an understanding of why smaller drives, here anyways, seem to put up the less fuss. |

I hope you did update the INF and IME driver, because if not, that might be the problem... IF you are lucky. Once you applied the Sandy to Ivy Bridge compatible BIOS update, BIOS version 2.10, you cannot, CANNOT go back to an earlier version. If you try to, things will not get better, they will get worse. That is why all the previous BIOS versions are no longer listed. A Windows BIOS update version? If one were available, I would not give it to my worst enemy. If any method is prone to failure, that is the one. Missing XMP profile option in the DRAM Configuration screen? That's a symptom of the 2.10 BIOS update not being done correctly, missing options in the BIOS. You must leave the USB flash drive in the PC until it completely boots into Windows after the 2.10 BIOS update. The IME firmware, part of the BIOS file, was updated after the BIOS itself, at least with this first instance of Intel's cross generation processors working with one chipset (Sandy and Ivy Bridge, P67 and Z68 chipsets.) That method has been discarded, and the IME firmware update is done first, not last. OMG, how I hate these Intel multi-processor UEFI/BIOS updates, they have gotten better now, but your board's chipset was the first to do this, and if not done perfectly, the results were not pretty. Or you may have a corrupted BIOS image. That Instant Flash no longer works seems to work is another clue about that possibly being the case. Did you try clearing the BIOS by removing the battery, and moving the jumper to the clear position? If you have the original battery in the board, that should be replaced. If that does not work, I would suggest getting a new BIOS chip with version 2.10 or an earlier version on it, if possible. As long as you are using a Sandy Bridge processor, you could use a pre-2.10 BIOS version, since 2.10 does nothing for a non-Ivy Bridge processor system. You can get a new BIOS chip from ASRock, or from eBay. ------------- http://valid.x86.fr/48rujh" rel="nofollow">
