Arrived on Friday.
6GB installed and I can see them in the slots so I know they are there.
However system only reports 2GB.
Only noticed it today when I started gaming and found games like Warcraft unplayable in memory intensive areas like Dalaran - seriously worse than my 5 year old laptop. Unable to tab out whilst playing without the HDD going mental for 5 minutes...

Saw you asking for details of the RAM in another thread so don't know if this helps:

Invoice number E1498763.
Further Edit:
I went into the BIOS and loaded the standard profile and upon rebooting I had 6GB again. So I went back and reloaded the OC profile and I still have 6GB.
Please advise on this as I notice other people are having memory issues like this due to a compatibility problem with a batch and I don't want to be checking my memory every time I boot up for the lifetime of the system!
I somehow suspect this will fail again within a day or two.
