In pursuit of further overclocks on graphics card memory, one looks into several aspects, such as memory voltages. When it does not help much, we start looking at cooling. RAMsinks are usually used for this purpose, but I was looking for something more cooling... a lot more cooling. I could throw some Dryice on the memory but that would entail the hassle of ordering dry ice everytime I want to do some benchmarking. So I decided to try out something extreme, using refrigeration phase change on the graphics card memory!
