Are we sure on the RAM clocks though? That's what's bugging me, 400 MHz RAM was nuts in 2001; they could have messed with it more than just downgrading it and increasing cpu multiplier.Flipper was the central chip in GameCube, so every other part in there ran at a multiple of Flippers clock speed. Before Flipper was down clocked the main memory would have been 400Mhz. Using the same 2x multiplier as the CPU. When they down clocked Flipper they left the RAM multiplier at 2 which dropped the RAM frequency to 324Mhz but they changed the CPU's multiplier to 3 which increased its frequency to 486Mhz.
I always thought it was a tradeoff so RAM could go higher, guessing it would be 202.5 MHz otherwise.
You're right, damn I'm rusty.Also technically speaking GameCube's 24MB of 1T-Sram is SDR rather than DDR, its just clocked at twice the speed of the GPU.
Still, a 405 MHz on RAM, in 2001 would be pretty nuts, we didn't know the full specs before launch though, so I'm guessing:
The 324 MHz bank, could have been hampered to be the same as the CPU bus.
If it was 405 MHz at some point then it was too high spec'ed.
EDIT:
The main memory of the Gamecube consists of two sets of 96Mbits 1T-SRAM. As it can drive a 64-bit data-bus at 400MHz
Nevermind. Quite crazy though.
