AMD Impresses Again With High Quality Solder; No Need To Delid Ryzen As Done With Some Intel CPUsBy Josh McClaren, UniversityHerald Reporter
AMD Ryzen delivers another impressive feature with the use of high-quality solder and TIM to ensure topnotch thermal conductivity with the lowest possible temperature as discovered by a professional overclocker and delidder. There is no longer any reason to delid the Ryzen as many overclockers usually do with some Intel Haswell and Skylake CPU with issues of overly heating.
Professional overclocker Roman Hartung or more popularly known as der8auer has successfully delidded a Ryzen CPU. He discovered that AMD spared no expense in ensuring topnotch build quality by using gold plated solder and Silicone protected caps. The video shows in detail materials used by AMD, like the solder layer on the die that connects it to the Ryzen's integrated heatspreader (IHS) and the extra layer of Silicone as additional protection. On top of that is the gold plating required to ensure topnotch Indium solder, wccftech reported.
Moreover, der8auer not only delidded Ryzen but also tested to see the temperature before and after delidding the chip as can be seen in the video below. The thermal comparison only posted a meager 2 degrees Celsius difference even when using direct die cooling with liquid metal as TIM. der8auer used the best case scenario in delidding Ryzen as is the common practice before putting back the IHS and avoid exposing the chip. Incidentally, der8auer killed two chips, which could be done either by scraping or scratching, before succeeding in his third attempt.
Delidding a chip is actually a risky process that could potentially kill the chip. It involves the process of actually removing the lid of the IHS from the package to lay the chip bare. In the video below, which is not a tutorial in any way, der8auer used a razor blade and some heating element to soften the glue and make separating the IHS easy. This is a tricky business only for professionals since AMD still uses bottom pins on the CPU, Kitguru has learned.
Delidding gives overclockers a fair idea of the thermal solution applied to the chips to ensure that it will not overly heat as seen in the Haswell Core i7 and i5 CPUs. It was actually Intel's Haswell that made delidding a common and popular practice as overclockers often replace the thermal compound used with a superior quality one. Intel's chips overly heat because of cost-cutting measures where Intel skipped soldering the IHS onto the die and opted for just a thermal compound. Intel still employs the same practice requiring delidding of some of its Haswell and Skylake chips.
With the AMD Ryzen CPU, delidding is no longer needed or even recommended. The Sunnyvale-based company has used the best quality materials where delidding is rendered useless with no tangible benefits. AMD once again proves its solid triple-pronged points on performance and efficiency combined with affordability.
