Also, Intel could have provided the 40mm fan for the NB.
The 4 mem slot at 1600 issue is, I believe, an XMP issue, not this particular board I guess. Not sure if other manufacturers support 1600 in all 4 slots.
Sound drivers are horrible, just lost the ability to select 5.1 setup in the drivers. Also, DD never worked. Crappy drivers, look horrible too.
Speaking of sound, still couldn't figure out what sound coded the DX58SO uses, I've seen the same IDT but also Realtek.
Intel has some problems with providing the correct information.
