NOTE: Between 32 and 64 MB of system memory may be allocated to support graphics, depending on system memory size and other factors.
Sometimes RAM doesn't properly seat, make sure this is not the case. The only other possibility is that you bought high density memory which is not compatible with all systems. The seller also states that it is not recommended for Intel chipsets, and your computer has an Intel chipset. And as always, they could have shipped you a broken one.
