So my last RAM had some faults and i bought some new RAM, which arrived today. I've tried putting it in my PC and when i boot it up it gets stuck in a loop of the fans all coming on for about half a second then everything shutting down, over and over again, never even making it so far as the BIOS logo.

My motherboard is Gigabyte GA-Z68XP-UD3 (rev. 1.3) (http://www.gigabyte.com/products/product-page.aspx?pid=3978#sp).

My new RAM is HX318C10FWK2/8 Kingston HyperX FURY Series 8GB (2x 4GB) DDR3 1866MHz CL10 (http://www.kingston.com/dataSheets/HX318C10FWK2_8.pdf)

My old RAM is BLS4G3D1609DS1S00 Crucial Ballistix Sport 8GB (2x 4GB) DDR3 1600Mhz (http://uk.crucial.com/ProductDisplay?urlRequestType=Base&catalogId=10153&categoryId=&productId=11362&urlLangId=-1&langId=-1&top_category=&parent_category_rn=&storeId=10153)

As far as i can tell, the new RAM and my motherboard should be compatible.

Kingston's own website lists this as compatible ram for my board (http://www.kingston.com/us/memory/search?DeviceType=2&Mfr=GIG&Line=GA-Z68XP-UD3&Model=72021&Description=Kingston_ValueRam_Memory_HyperX_Memory_for_Gigabyte_GA-Z68XP-UD3_Motherboard)

I've tried both sticks in together and both individually in both the Channel A and Channel B slots. Nothing works.

After asking on another tech support site and Googling around for answers, here's a list of what I've tried so far:

Checked Motherboard capacitors
Cleared the CMOS
Flashed the BIOS to the latest version (F10)
Made sure the memory setting in the bios were set to Auto
Tried changing the settings to match the new RAM speed specifically (1866Mhz)
Changed the DRAM voltage from Auto (1.5v for this RAM) to 1.6v
Tried manually setting the latency for the new RAM in the BIOS.

None of this has worked. I am able to turn on my PC with one of the new RAM sticks in (I haven't tried with 2) as long as the one remaining functioning stick from my last set of RAM is also inserted in the other dual-channel slot 1. This is how i was able to get as far as the BIOS to try some of the above methods since it never boots that far at all with just the new RAM in.

Interestingly, when i have 1x4GB stick of the old RAM and 1x4GB of the new RAM in, my computer does read as having 8GB, despite not starting at all with only the new RAM. Here's a photo i took from the BIOS showing this (https://i.imgur.com/h0wGcee.jpg)

I've ran out of ideas for things to try so if anyone has any ideas that may help then I'd really like to hear them.

All that happens is the fans spin up for a second and then the whole thing powers down. Rinse and repeat.

I found the solution (though not 100% ideal) on another tech support forum. I needed to restrict the new RAM's speed to 1600MHz in the BIOS (despite my motherboard supposedly supporting 1866MHz, which this RAM is).

Hi,

I recently ran into the same problem as you. Have you done anything different since? Or was manually putting in the RAM speed all you did up until now.
