System: - H97M Pro ASROCK Motherboard. (brand new) - Intel Core i7-4790K Devil's Canyon Quad Core 4.0 GHz LGA 1150 CPU. (brand new) - 4x Corsair DDR3 1333 Memory (9-9-9-24) (all brand new) - 850watt Power Supply - Geforce GTX-1080 (8gb) GPU. - Crucial 128gb SSD drive (OS only). - Seagate 1TB HD - Windows 10. Installed all components. Started by placing each RAM chip into the furthest right memory slot on the MB. All RAM works alone. (PC came up fine showing 8gb memory). Placed 2 RAM chips in the two furthest right memory slots (B1 and B2). All RAM works paired up. (PC came up fine showing 16gb memory). Placed all 4 RAM into all slots. Nothing. Absolutely nothing. After about 20 seconds or so, the PC would power itself down, then restart and try again. Tried adjusting the voltage to the DRAM to 1.55 volts. No luck there. At my wit's end here. Unable to upgrade this machine to 32gb. Also, when running Black Desert (MMO), it has a tendency to crash (not due to the GPU. swapped the GPU to a different machine, and it worked fine there). Any help would be greatly appreciated. Thanks! |

Your four sticks, the came in the same package as a matched kit? |

They came together in 2 packs (2 x 8 gb). All 4 seem to be exactly the same (model number, etc). Ordered from the same company, at the same time. |

Meh, sometimes you can get lucky by not buying and using matched sticks. Two things .......... 1. Pair up your sticks by S/N and use them as such. My guess is when paired by SN, as a single pair they'll play nice in Dual Channel mode. 2. In CPU-z's SPD tab, compare the timings and voltage for/while each Kit(2x8GB) Kit is installed, looking for differences between the two Kits |

| They are the same kits. Same exact everything. Came in pairs in 2 packages. |

Sorry, but you do not have a matched kit of memory. A matched kit of memory comes in one package, the end. Corsair and most memory "manufactures" do not manufacture their own memory chips, meaning the actual DRAM memory chips used on a memory "stick", or DIMM. They buy memory chips in bulk at various times, from multiple manufactures, Hynex, Samsung, Micron, etc. The same model of memory from Corsair may have memory chips from any of the memory chip manufactures. They will have differences that don't allow them to work together. That's why memory is sold in kits of multiple DIMMs. Mixing multiple kits of memory is a gamble, they may be compatible, or not. The best you can do is put one kit in one channel, and the other in another channel. Can you tell the two kits apart at this point? The memory controller (IMC) is part of the CPU, since Intel changed to the single chipset design in 2008 - 2009. The mother board has much less influence on memory compatibility than the CPU (IMC) does. DDR3 1333 memory should be very easy for any PC to use. When you put all four DIMMs in the board, are you clearing the BIOS/CMOS before starting the PC again? That really should be done whenever you change the memory slots being used, or when adding or removing memory from the PC. You said this in your first post:
This does not seem to make sense. If the PC would not POST or boot the OS, how did you get into the UEFI/BIOS to change the DRAM voltage? Did you remove two DIMMs, go into the UEFI, increase the voltage, and then put the two DIMMs back? What is the full model number of the Corsair kits you have? ------------- http://valid.x86.fr/48rujh" rel="nofollow">
