Now to my problem.

 

I have the two RAM sticks installed in DDR3_1 und DDR3_3. (The to white ones)

 

When I put them in the blue slots the PC won't boot.

 

 

In this picture you can see that the bios recognizes both sticks but somehow it only enables 1 of them. Windows 8 64b also shows the same.

I'm pretty sure that it is not the RAMs fault as I had the same problem with different sticks.

 

Do you have any Idea how I can enable both of them to use the full 8 gb.

 

 

(I hope you understand what I mean and my english is not that bad.)

Have you tried both sticks individually? Have you tried to change slots? And turn down the base clock to 100 MHz to see if that helps (unless it's necessary to have it at 133.27 MHz)

I have also put them in slots 2 and 4 --> no POST just an endless beep

 

I have put them in slots 2 and 3 ---> it was the same as in the picture from my first post just that in DIMM SLOT (MB) the 4gb where written unter 2 and 3 but no other changes.

 

When I change the BCLK this happens:

You could try reseating the CPU or change the motherboard

I already tried reseating the CPU and I don't have another MB

133 MHz is stock tho but agree on testing each stick

I didn't realise that it is stock for that MoBo

Have you tried to clear CMOS?

I've tested both sticks. In slot 3 both work ( I only tested this slot because I would have to deinstall my CPU cooler otherwise.

 

Now I put them in Slot 3 and 4 (next to each other, one blue slot and one is white)

 

And now it shows 8GB. But I guess it is nt running in dual channel? Wil it be slower or is it fine?

I don't really think you're going to notice a big difference, depending on what you use your system for.

Actually only gaming.

Then you shouldn't notice a difference
