While the standard NVIDIA GeForce 7300 GS comes at a core clock speed of 550MHz and 810MHz DDR for the memory, Chaintech offers an even lower-end version of this by using 256MB worth of cheaper DDR2 memory rated at 3.7ns compared to the usual 2.5ns used. In view of that, the memory clock also has been revised accordingly with the end result at a low 533MHz DDR.
