该机器为宏碁（Acer）台式机上的定制内存，所谓的 GDDR 是误导写法。
I have the same memory installed on a Gateway with ACER MoBo….here’s what I know so far…that memory is FULLY BUFFERED and the MoBo probably won’t recognize unbuffered SDRAM. Mine is also labeled GDDR3-1333 and bears the part number GU512303EP0202. My conclusion after much surfing and reading is that the machine will run best with the buffered memory in it and I’m simply going to have to wait for 4GB buffered modules to become available. Buffered memory is a tad slower due to the buffer read, but is much less error-prone and thus the machine should be more stable. Servers, routers, and MACs all run buffered memory. As for the GDDR3 it should designate graphics memory which should not work as system memory unless some proprietary MoBo innovation has been created. I wonder if the memory was simply mis-labeled GDDR3?
