It is. The GPU core pushes a lot of heat out through the traces into the memory. This is exactly why when on my Ti4600, I can higher memory overclocks, despite the need to remove the ram heatsinks, when I water-cool the GPU core, as opposed to the default configuration.
A lot of the heat from the GPU core makes its way out to the ram chips. The reverse is therefore true if the GPU core is chilled with a peltier, and this directly explains why the memory can be clocked dramatically higher when the GPU core is cooled better.
