It seems this ram is out of stock where I've checked. However there are the KHX1800C9AD3T1K3 which are the same specs but there is an "A" in the part number. Anyone know the difference?
Do you mean Kingston HyperX KHX2000C9AD3T1K3/6GX?
These have same specs....
...but have some Elpida BDBG Chips (65nm like the BBSE) under the HS.
Is nearly the same (also trcd limited) but do not like that much voltage....
