Overclocker Delids AMD Ryzen 7900X, Lowers Temps by 20C

Some of the stunning bits of stories from this week’s Zen 4 launch was how sizzling AMD’s latest CPUs can get. That is by design, based on AMD, but it surely conjures up ideas of a Star Wars meme: You have been imagined to destroy the Sith (Intel), not be part of them! AMD has joined the darkish aspect although, with its new high-end hips working at 95C, even on beefy liquid cooling setups. As we reported beforehand, they eat extra energy than any earlier AMD processor—greater than 200 watts.
Overclocker Delids AMD Ryzen 7900X, Lowers Temps by 20C
A key wrongdoer for these excessive temps is supposedly the additional thick built-in warmth spreader (IHS). AMD apparently made it this method to assure compatibility with older AM4 coolers. Naturally, overclockers have already gone to work on the brand new chip to see what how efficient direct-die cooling could be by delidding the CPU. The outcomes are fairly stunning, but it surely’s not one thing an off-the-cuff fanatic ought to ever try.
Famous overclocker Der8auer is a delidding skilled, so he figured he’d strive it out on AMD’s newest CPUs. As you're conscious, AMD’s IHS design is a bit totally different from Intel’s, with cutouts throughout the sides. This makes the delidding course of a bit extra complicated than regular, so he needed to create a prototype mechanism. It clamps down onto the IHS, then makes use of stress from reverse instructions to shift the IHS 1mm forwards and backwards till it comes free. With the “lid” eliminated, he then fabricated a body to go across the CPU to carry the cooler in place. With assist from AMD CAD recordsdata and his personal 3D scanner, he may design a body and mill it on a CNC machine.
He additionally notes that Zen 4’s backplate mounts on to the socket mounting mechanism. It’s known as a socket actuation mechanism, or SAM for brief. This implies an AM4 cooler with a backplate won't work on AM5 with out some form of adapter, a reasonably large caveat in AMD’s declare that AM4 coolers will work with AM5.
Along with his body constructed, and the chiplets uncovered, he gingerly mounted his cooler to the chip. It’s comprised of a 360mm corsair radiator and followers with a customized pump, reservoir, and tubing. Earlier than doing all of the legwork to take away the lid, he ran Cinebench with a inventory setup for a baseline. The CPU was clocked to five.4GHz throughout all cores, and hit temps of 90C. As soon as delidded, he ran the check once more with the identical clock speeds, identical BIOS, and identical voltage. Surprisingly, the chip was in a position to run Cinebench at a cold 70C. That’s a surprising 20C drop in temps with every thing else unchanged. One ancillary advantage of the experiment is the chip consumed about 15W much less energy as a result of decrease temps. He was additionally in a position to bump the clocks up 100MHz by including 30 millivolts of juice. That gave him 5.5Ghz throughout all 24 threads.
This can be a stark departure from earlier Ryzen delidding experiments. We discovered a video of his from 2017 the place he delidded a Ryzen 7 1800X, and located nearly no temperature distinction. All of it comes all the way down to the thermal interface materials (TIM) design by AMD. For Zen 4 AMD makes use of solder, which is best than common thermal paste. Nevertheless, the thick IHS could be contributing to the chips’ excessive temperatures.
General, most individuals won't wish to jeopardize their costly processors to try this. Nevertheless, it’s an fascinating have a look at the chances Zen 4 provides to modders. It additionally reveals that Zen 4 CPUs can run good and funky, even overclocked. Additionally, it’s doable Der8auer will make his delidder mechanism and CPU body out there at retail. He’s completed that previously for earlier CPUs. You'll nonetheless should be extraordinarily cautious when utilizing it, although—and be capable of face up to the demise of your CPU, ought to issues go sideways.
