I ordered 4 units of KVR333X64C25/512 memory for my ABIT KX7-333 motherboard.
I installed the memory properly (grounding myself, etc) only to get 1 long beep indicating a POST error with the memory.
I thoroughly cleaned the mobo and the DIMM slots.

I tried multiple combinations of sticks in DIMM slots 1&2, 3&4, 123&4 to no avail.
I reset cmos data, loaded failsafe BIOS values, reset ECSD data, all to no avail.

When I put my old 256MB sticks back in it worked fine.
I checked the Kingston website and this memory 'KVR333X64C25/512' is compatible with my mobo.

I returned the memory bubble-warpped to aria.
I then got an emial saying they had 'tested' the memory only to find no error (!)

At this point I asked for a refund and have heard nothing from them.
As they appear to be badly unprofessional I will contact my bank to issue a charge back against them.

I strongly advise anyone NOT to purchase ANYTHING from aria as they are abyssmal.
