Exotic Cooling In Adata 'JellyFish' RAM Project

LAS VEGAS, NV -- Adata's Project JellyFish isn't the wildest system memory design we've ever seen, but it's certainly the...wettest. At CES 2018, the company displayed a working prototype of a fluid-filled plastic shell that encapsulated a fairly traditional DDR4 DIMM. The liquid inside the housing is non-conductive and has been used for exotic computer displays for years by companies looking for attention at trade shows.

Adata is the first that we know of to combine the chemical in a DRAM module. We were told the company has a patent on the design, but don't expect to purchase JellyFish DRAM anytime soon. We were told these are working prototypes but not final designs. At this time, we're not even sure if this product will come to market.

The JellyFish DDR4 DIMMs feature a row of LEDs across the top of the circuit board that alternate colors when powered on. The display was fairly low tech, with a simple display that just powers the two drives Adata had in the booth. Adata didn't run the RAM in a system, so we don't know the true cooling capabilities. If these come to market, we should expect some way to cool the liquid. An expansion chamber would also help to raise the level of fluid in the module. In the prototypes we saw on display, the liquid didn't cover every DRAM package on the board. The top packages would go without liquid cooling in an upright desktop computer.

    Liquid to keep it cool and a plastic case to do the opposite of that.

    The amount of pressure you have to push down on the plastic covered RAM to seat it properly, tells me this is not going to be a good idea.

    Reminds me of the PC builds that I've seen inside of an aquarium full of ... I forget. (Mineral oil?).

    They always left me thinking "okay, so now the heat is away from the chips, but how do you get it out of the big plastic tank?" The oil might start out cold, but given enough time the fluid itself will still heat up to a dangerous level if you can't transfer heat into the air. That's why traditional liquid cooling has a radiator.
