Hi there,

Any help that anyone could provide would be greatly appreciated.

I recently bought a new motherboard and processor. The components that I have are:

Asus Maximus Ranger 7
i5 4690k cooled with a Seidon 120m closed loop cooler.
An R290 graphics card
Corsair TX 850w PSU.

A week or two ago when I first put it together I couldn't get it to boot with the 4 sticks of 2Gb RAM that I had, I was getting Qcode 55. It would boot with only one stick in the B1 slot. I suspected that I had faulty RAM slots so I got a replacement mobo from Amazon and installed that.

In the meantime I ordered an 8Gb stick of Corsair Vengeance RAM. When this arrived I used this in the same slot as before (in the new mobo) as again it would not boot when it was in any of the other slots. Everything seemed to be running smoothly the last two weeks. Until today when my second 8Gb stick of RAM arrived. I tried to install it in the two slots as instructed in the manual (A2 + B2) and the system just refuses to boot. It powers up and powers off constantly, getting nowhere. I pressed the MEMOK button and then it just shows the Qcode 55. Powers up and powers down showing 55 and then 10.

Any advice would be fantastic as I am getting to the end of my tether here.


Thanks in advance.

Just thought I would add that both the sticks work fine as long as only one is in at a time. Can run Prime95 indefinitely without any issues arising either.
 
ya I had a asus board that did this and as long as it just had one stick it worked just fine at default anything more than that = fail

so seing my last few asus boards were problematic I just don't conceder them any more . there just not the asus I grew up with - high on hype low on quality

eaven my buddy who built nothing but asus finaly got away from them


I do hope you can resolve your issue easy but if like me I spent good money trying different memory and what ever just to find it was a no go but all the parts from the asus went right on another brand board and worked with out issues

good luck

Yeah, had read a lot of similar issues. Checked all my pins in CPU socket also.

Think I am just going to have to bite the bullet and return it and go for something else. Just when I had all my cabling nice and neat as well!

Thanks for the input guys, much appreciated.
