I have a working Window 7 Home Premium 64bit PC working perfectly with 2 x 4GB DDR3 RAM for 8GB of memory.
I upgraded the memory to 16 GB DDR3 by buying 2 additional 4 GB modules of the exact same memory (same brand, model number, speed, timing, etc. Corsairs Vengeance CMZ8GX3M2A1600C9), but Windows 7 now will not load with 16 GB of RAM and it stops booting after the "Starting Windows" screen with the multicolor windows logo rolling/flashing.
I have already checked that the new memory modules are good. I can load Windows if I use 2 x 4 GB RAM of the new memory, or 2 x 4 GB of the old memory, and even if I mix one 4 GB stick of the old memory and one 4GB stick of the new memory. As long as I boot with 8 GB, Windows will boot and get to the desktop. My computer will even work as a HackIntosh with all 4 x 4 GB memory sticks installed and OS X will load and work with 16 GB of RAM.
My motherboard (Gigabyte GA-Z68M-D2H rev 1.0) has 4 DDR3 memory slots, and according to the manual, it can support up to 32 GB of RAM. I also know that Windows 7 Home Premium 64 bit will support up to 16 GB of RAM. I verified that I have Windows 7 Home Premium 64 bit, activated and validated as genuine Windows.
BIOS boots with 4 x 4 GB RAM, and it shows all 16 GB installed and working properly. The BIOS setting for the memory is the stock speed 1600 MHZ (I even tried 1333 MHz) at stock 1.5 volts and stock/auto 9-9-9-24 timing. After the POST, it shows that 15.6 GB is available (because I am using 480 MB as integrated video memory for the Intel HD 3000 integrated video "card" provided by my Intel i5-2500K CPU running at stock 3.3 MHz. Everything goes well, windows starts, the color windows logo comes on, the hard drive blinks as it is loading windows, but then it stops and does not continue to load the desktop. There are no error messages, it does not seem like it is frozen as the color windows logo continues to roll/flash. The hard drive eventually stops loading, and that is it. It fails to boot to the desktop and just stops there with the color windows logo rotating/flashing around the 4 colors of the windows logo.
Is there some settings I need to set on Windows 7 while I log in with 8 GB of RAM to make windows recognize 16 GB or boot with 16 GB? Is there a driver I need to install, a windows update or fix? I have applied all windows updates provided by the automatic windows update, and even installed any missing updates as found by Belarck Advisor 8.x.
I think I have done everything by the book, but no go. What else could I be missing?
I already updated the motherboard BIOS to the latest BIOS from Gigabyte (BIOS F6, the latest before going to EUFI beta BIOS). The only thing I can think of is that I did not get all 4 x 4 GB of RAM all at once from one pre-packaged 4 x 4 GB package. I got 2 x 4 GB 1 year ago, and the same model from the same manufacturer 2 x 4 GB this year. The RAM module markings all says the exact same things, except that the year old ones say version 3.4 and the new one say version 4.2. Or is it possible that having all 4 DDR# slots full can cause some problem? But since all the memory modules are all booting on the BIOS and working even when mixed, as long as it is 8 GB on Windows 7 and 16t GB on OS X, I don't think it is the physical memory or the motherboard. I think it is something to do with Windows 7 Home Premium 64 bit.
I haven't got any further clue. If you have any suggestions, please let me know. Anyone else able to run Windows 7 Home Premium 64 bit with 16 GB of RAM?
