I am trying to get 4 of the memory sticks i have working and I'm afraid of the motherboard or the slots are messed up. I'm wondering if there's any way to rule them out, because I'm not ready to give up on the motherboard yet.

Here is my Ram:
G.Skill RipjawsX F3-12800CL9D-8GBXL DDR3 - 1600 CL9-9-9-24 1.5v pc3 12800 4gx2 Intel XMP Ready. Barcode 154521004162109 it says they are from 2015 NOV

I bought two new ones and its the same exact specs except its from March 2017 Barcode 171314H00923211

Motherboard is:
Gigabyte GA-Z97X-SLI

Bios is:
Flash Memory Type: MXIC 25L64 Series
Flash Memory Size: 64M bits
Bios Sign on Message: Z97X-SLI F9
Bios Vender: AMI UEFI Bios

Cpu: Intel(R) Core(TM) i7-4790k CPU @4.00GHz 4.00GHz

My Operating system is 64bit Windows 10 home Edition

I saw that it might just be the two different rams not compatible with each other but that doesn't make since to me because they seem the same, and if their not I'm wondering if i can do something in the bios to make them work together.

I don't know anything about voltages and timing but I think you can change some of that in bios too.

I tried XMP mode but that didn't work

the symptoms are always the same it starts up beeps many times then reboots over and over. this is before you can enter the bios

I don't know if the motherboard is working in dual channel or single channel mode but it definitely says it supports dual channel. my manual says i can enable dual channel function on the motherboard bios but there is no setting to do so there, I was thinking it might not be set to a certain mode.

Ram lay out goes 1grey 3black 2grey 4black where 4 is closest to cpu both stick sets work on slot 1 and 3 but not in any other configuration

It's possible that the slots might be broken but so many people have the same problem that I'm thinking that's not the case but it acted the same when i first built the computer. I'm wondering if I can make sure a slot Isn't working right.

Any help would be awesome thanks.

Even memory with the same part number will not necessarily work together if bought separately. All memory should ideally come from the same dual channel kit to ensure inter-module compatibility.

As suggested, check the CPU and its socket for damaged pins/pads. There shouldn't be any dust, dirt, debris nor anything else on or amongst the pins and pads.

Make sure the CPU is mounted evenly, as uneven mounting can cause contact issues between pins and pads which in turn leads to all sorts of system problems.

Check all memory slots for signs of damage, and check for dust, dirt or anything else that might be in the slots.

Make sure ALL cables and wires that need to be connected are connected properly.

Make sure the video card is...


Do you want a guarantee modules will play nice? Buy them in a kit.

Some boards require that you install the modules in a specific order. I would find your manual and see if that is the case.

Make sure the video card is installed firmly also.

Clear CMOS.

Try ONE memory module at a time in slot 1, until all four modules have been tried. This will help determine if one or more modules are faulty.

If all modules seem to be OK, then install all four modules firmly.

If can boot into BIOS, but no further, then raise DRAM Voltage by 0.05 V, but don't exceed 1.65 V.
