According to what I have been able to find to hardware specifications for my PC, it does support 1333Mhz RAM. Unfortunately, I found that when I go from three sticks to four, it automatically drops the RAM speed to 1066Mhz.
Sadly, I have also found out the hard way, that HP seems to only care about a new PC so long as it is still in production and on the market. None of the included software, drivers, or firmware have had any released updates in a very long time.
My question being as far as the RAM goes, is there anything at all that I can do in order to make it still run at 1333Mhz, or am I stuck between a rock and a hard place, i.e. the choice of 3 sticks at a max of 12GB of running at 1333Mhz, or use 16GB at a max but only at 1066Mhz? I honestly wouldn't care about the limitation if I could put 8GB in each memory slot. I am unsure if this is just because of a limitation based on using a AMD Phenom II x6 3.2Ghz processor, or if it is a limitation because of the H-RS880-uATX (Aloe) motherboard, or some combination of both?
Would there be something I could do in the BIOS to force it to run the RAM at 1333Mhz? If not, would there be a update to the motherboard firmware that I've been unable to find?
