I have an Intel DQ45EK. On this board i have 2x2GB Transcend RAM. This worked some time ago.
Now i updated the BIOS to the newest version and now i can't install a 64-bit system anymore (tried Windows Server 2008 and Windows Server 2008 R2). They stop installing or run veeery slowly.
If i use only 2GB RAM, they work fine. I tested my RAM with memtest86+ 4.00 and they seem to be ok. memtest also run veeeeeery slowly if i have 4GB installed, if i check only 2GB at once, it works fine.
My problem seems to be similar to this:
Is there any possibility to use 4GB RAM?
