Adata Shows Off “Liquid Cooled” RAM at CES, Project Jellyfish

We’re getting into the realm of very intricate ideas in cooling components and that’s saying a lot. Your widely accepted air coolers almost always use heatpipes, which are actually engineered with a substance that phase changes inside, helping move the heat through to the fins. As good as that gets, crazy people found out that using water in a loop with a radiator was even more effective, deciding the risk of frying a system was worth the benefit. Now, Adata is taking things to a new level that, while already existing in other capacities, is bound to be a first for RAM cooling. First, let’s talk about the concept of these modules being liquid cooled. While generally speaking, this is correct, it’s technically somewhat inaccurate. Liquid cooling generally correlates to transferring heat out of the component by means of, say water, as the vehicle to carry it away. It ends up being a simple transfer of heat from the source to the air. The liquid that’s in these modules is called Fluorinert, which is using a process of cooling called “phase change.” This particular chemical, developed by 3M, can boil at temperatures as low as 34c depending on the variant. As liquid boils, it actually consumes a large portion of the heat being generated, as opposed to transferring it to a less heat saturated area. Thus you have the concept Adata is introducing, but while this looks pretty new for RAM, it’s been implemented in the server environmen...

Samsung Announces HBM2 Aquabolt, Getting Closer to Really Mainstream

How did I miss that Samsung is producing HBM? Maybe I didn’t miss it, but I just forgot by the time I saw this announcement. Samsung has improved the performance of HBM2 by a pretty large margin and they’re continuing to ramp up production in order to provide supply to manufacturers abroad. We get it! HBM2 is really fast and since you can get the technical details from the link below, I want to explain what I hope to see in the near future with better/cheaper HBM2. The biggest gaping hole in the market that I see is the lack of HBM in RAM sticks. I’m sure this will mean new motherboards, chipsets, the whole nine yards, yet I can only imagine what this development could mean. Not only would we have aggressively impressive memory performance, but I would be willing to bet that RAM slots would get trimmed down to the size of a SODIMM slot on a regular ATX sized motherboard. While mainstream and gaming boards wouldn’t require an excess of 4 slots, imagine a platform like Threadripper being able to squeeze 16 slots into one board! Even then, we may see a day when CPUs have HBM2 built into the die and RAM slots could be completely obsolete, though I feel like having a small slot is better for upgrade or replacement purposes. We’ve already seen the power and size efficiency of HBM on graphics cards, but wouldn’t it be great if every card came equipped with the technology, rather than only high end GPUs? Samsung is definitely helping make HBM2 a...
