We used our Elsa Erazor X² 32 MB DDR. We made 8 small heatsinks - the surface were sandblasted and we polished the surface against the memory modules. The heatsinks were then glued on to the memory modules with Loctite 326 which transfers heat very well. A 120mm Papst fan was installed to blow air over the coolers.
We tried to overclock the memory clock frequency above 370MHz which we managed without the heatsinks - but no way we could run it higher than we did without them !
Het hielp dus niks, maar het ziet er wel errug cool uit!
