Weird memory-issue

Okay, I think I know what the problem is here. Most likely, there's some error with the motherboard. Yet, since I'm a person who can't be sure of this completely, asks SP if it is possible that this is possible to fix. Mind you, I'm putting this into Rubriks Cube, because even though it's a technical issue, this seems to require some brainpower in order to understand.

I have two sticks of RAM: 1600 MHz, CL9, 1.65V

On my new motherboard (Asus M4A79T Deluxe), the slots for my RAM is set up like this:

Code:

P [color=DarkOrange]1 2[/color] 3 4

Where P is the CPU.

My RAM-voltage is set at 1.66V, which is the most correct voltage my ram needs. Rest is set on auto.

Now, some weird pomegranate is going on. If I only have 1 ram-stick in, my computer will only boot if the ram-stick is in slot 1 or 2. If I have them on 3 or 4, it won't boot.

Also, if I have more than 1 memory-stick in, regardless of their position, the computer won't boot.

Which is kinda weird, isn't it? Is there any rational solution on this issue that I might have overlooked?

Hmmmm, from what i remember from reading and my PC repair class, its either a dual channel issue, a memory controller issue, and a placement issue. But you said that it wont work with 2 in any setup. Have you tried slot 1 and slot 3? or even slot 2 and slot 4? It may be a bios setting or a jumper. So many thing it could be (maybe not a jumper as much as others).

You need to check if your motherboard supports the RAM you're using. Having it only work on 1 or 2 is normal if you don't have any other RAM in those slots. As of it doesn't take more than one stick, I would try looking at the mobo manual first, test out jumpers if needed, but most important of all, flash it with the latest bios if possible. When you say it won't boot, does it at least load up to POST? Also, you can check out forum.desktopreview.com, they usually deal with common problems.

The motherboard supports the RAM I'm using.
It does not load POST: It does simply put not load.
No jumper for the RAM (Unless you're asking me to clear the RTC-RAM, which obviously isn't the case).

What could be of information, is that the fan starts out hard for like 1-2 sec, then the fans slow down for 0.2 seconds and repeat.
Happens at startup with:
1 memory stick in slot 1/2,
2 memory sticks in slot 1 and 2,
2+ memory sticks, where slot 1/2 is used, and 1+ of slot 3 and 4 is used.

HOWEVER, when using only 3, 4 or both, there is no such fan-sound. The fans then just run normally as if nothing was wrong. Well, the system does not react at all, kinda.

Im thinking its a controller problem of some sort. Not too sure. At this point tho, id just take it in and hope someone else can get it working (hopefully they dont try you to buy a new motherboard or RAM or both).

but most important of all, flash it with the latest bios if possible.

Which did the trick.

I thought I had a relatively new bios though. Guess I was wrong about that.

You probably only had to clear CMOS.

Nope. I had to update my bios, and that's it.

My old BIOS-firmware decided to not support the newest RAM-sticks/CPUs out there, so...
