However, if there are only 4 modules it should be 256Mx4 which brings it to only 1Gb of ram. 4Gbit equates to 512Mb, So 4Gbit x 4 = 2Gb of ram, which is what it should be and isn't listed in that particular memory's product specifications. |
Dude, why do write so much if you don't understand it?
256M*16 means 256MBit * 16bit wide ram, so one chip has 512 MByte data. Four chips = 2 GByte, what is so difficult?
However, it is surprising they went with a single Dram controller (usually 64bit wide in every CPU/GPU). That is al ot of bandwidth lost for a unified design.
Just checked it's gDDR3 chips (whatever that is - SDDR3?)
