All PlayStation 2 consoles are capable of the same documented video modes. The only exception that we know of, is the 576P mode (0x53), which was added with the SCPH-50000 and later, but I don't know where it is even used... I don't think it was ever mentioned in any Sony documents we have now. If somebody has a proper answer to this, I am interested too. I guess it was related to the Sanyo OP block. The F-chassis (GH-015) was the first model to be documented to support the Sanyo SF-HD7. The interesting thing is that the GH-013 is also found under the R-type console model. @l_oliveira mentioned before that despite it not being documented to support the SF-HD7, it seemed to be capable of it because of what it does when the SF-HD7 is installed. When the wrong OP block is installed, the PS2 will fail to read discs, but newer models seem to eventually switch over to the right defaults for the SF-HD7. Since the GH-013 seemed to be able to do it, it might have the capabilities for it. But who knows whether it was really meant for this. Or it could be something like "Refresh", since the only regions with these models only included US & Europe, which already had earlier expansion bay models (B & C chassis). There were also quite a number of D-chassis mainboard models, with some under the SCPH-300xx & SCPH-350xx models, to make things confusing. When Japan got the first expansion-bay PS2, it was a D-chassis SCPH-30000. The GH-013 is a D-chassis model, while GH-015 is a F-chassis. The F-chassis had a number of new things, like the BGA-mounted MECHACON (CXP103049), support for the new Rohm RTC, support for both the Sony and Sanyo OP blocks. D-chassis models included GH-010, GH-012, GH-013, GH-014, GH-016.
