Graphics Card Specifications 1 core, memory filter with inductor and capacitor 2 voltage conversion chip 3 memory VDD / VDDQ control chip 4 GPU core voltage with MOSFET 5 GPU core voltage control chip 6 video control chip empty welding bit Product Description 9550 and 9600 Are based on the RV350 core, but the two show the core and the memory of the frequency of work there is nothing. As long as the graphics card power supply circuit and memory quality excellent, can transform 9550 into 9600. MSI 9550 Platinum Edition uses Samsung 3. 3ns memory, so very successful transformation of the potential. Weixing 9550 Platinum Edition memory from the front and back sides affixed with four 16M × 16bit TSOP Ⅱ package chip, the total memory capacity of 128MB, the total bit width of 128bit. Power supply system, the use of a piece of code for the AMS1117-0444 MOSFET tube for the core power supply; memory VDD / VDDQ use ISL6522CB-P445CNS as the control chip; and memory bus termination voltage is controlled using the PM39DE chip. Memory, the core of the power supply part of the filter, conversion capacitors, inductors use large quantities of aluminum surface mount capacitors and surface mount inductors. Cooling part of the memory as the default frequency of only 400MHz, so only the display core using a wind turbine
