Then why does Nvidia list the Tesla K40 as GDDR5 SGRAM, but advertise the GTX 780 as being simply GDDR5? If GDDR5 is natively SGRAM, then why the redundancy when advertising the Tesla K40? All you have done is confirmed what was already said - GDDR5 SGRAM exists. You have not proven that the GTX 780 uses SGRAM, nor have you proven that VRAM (as a technology) is no longer in circulation. I don't care if it peeves you to see people refer to the integrated memory of a GPU as VRAM. The simple fact that you are derailing the thread is a clear indicator that you are making a desperate attempt at grasping straws to validate your competence. To the point of the thread, it doesn't matter if a GTX 780 uses SGRAM or VRAM as a memory technology. Proving it either which way has no bearing on PS2's UI being a "power virus". As such, get back on topic.
