Delidding The AMD Ryzen 5 2400: Delidding The APU

To show if delidding the Ryzen 2000 series APUs yielded much benefit in terms of thermal performance and overclocking headroom, I selected the best overclocking chip for delidding from a CPU core frequency standpoint out of a pool of four APUs. The best one was our retail Ryzen 5 2400G chip, which managed 4.1 GHz with 1.387 volts applied in the BIOS (on our MSI B350I Pro AC motherboard).

For delidding, we purchased the Der8auer Delid Die Mate 2 delidding tool, and the Delid Die Mate 2 AMD Kit. This to our knowledge is the safest method to ensure the APU is not damaged during the delidding process and the Delid Die Mate 2 is manufactured from good quality anodized aluminum; much sturdier than a 3D printed acrylic one which relies on the quality of materials used to print. Ensuring the delidding process has minimal risks means a safe delid without damage which is ultimately is much cheaper than a dead piece of silicon, one which cannot be RMA’d due to voiding the warranty outright. The actual procedure for delidding the Ryzen 5 2400G ($169) is exactly identical to the Ryzen 3 2200G ($99) in every single way.

Step 1 – Ensuring the Tools Are Ready for the Job

The process in removing the IHS from the 2400G die is very simple (using the right tools), although it can be daunting to first timers and non-experienced users. The first step is ensuring the tools contents are correct and there is no present damage to the components; doing this is essential as any imperfections or cracks in the metal could cause the tool to break in operation and could destroy the chip.

Step 2 – Putting the Chip in the Tool

Making sure the chip is placed into the tool the correct way allows the tool can do its job properly; putting a case fan the wrong way around in a chassis wouldn’t give the right thermal dynamics to effectively cool a system, doing the same with a processor in a delidding tool wouldn’t be right either.

The way to make sure the chip is in the correct way is to line up the triangle indicator on the corner of the processor itself with the triangle indicator on the tool, the same way you would when installing a processor into a motherboard.

Step 3 – Assembling the Die Mate 2 with the AMD Kit Correctly

With the Ryzen 3 2200G ($99) or Ryzen 5 2400G ($169) correctly placed in the Delid Die Mate 2 tool, the next step is slotting in the red acrylic adapter at the open end of the tool; the U-shaped groove needs to be facing upwards as this is where the threaded bolt sits to protect it from touching and potentially damaging the pins on the chip.

Step 4 – Slotting in The Delidder

The Der8auer Delid Die Mate 2 as standard comes in three main components, the part that holds the chip, the part that removes the IHS from the chip, and an adjustable clamp to hold the chip in place. The clamp isn’t used when delidding the AMD Ryzen 2000 series APUs due to the chip using pins. Lining up the grooves in the black block of aluminum with that of the other part of the tool is essential and for ease of use, it can only be placed in one particular way.

Step 5 – Inserting the Threaded Bolt from the Delid Die Mate 2 AMD Kit

This is where the included acrylic adapter comes to use to prevent the bolt from hitting any pins and thus avoiding damage. The M6 x 60 mm threaded bolt screw included in the AMD kit is paramount and using the regular one supplied with the tool itself wouldn’t be adequate to delid a Ryzen 2000 series APU. The aim is to secure the bolt into the correctly sized slot on the Delid Die Mate 2 tool so that it’s ready to be used.

Step 6 – The Nitty Gritty: Applying Force and Twisting the Nut

The Delid Die Mate 2 comes included with an Allen key which is required to screw the bolt with enough pressure to ‘pop’ the heat sink off safely. Both the standard supplied bolt and the one with the AMD kit share the same M6 sizing making the key usable on both threaded screws. With the bolt in place and the Ryzen 5 2400G ($169) safely installed into the tool, it’s a case of simply twisting the Allen key until the loud popping sound is heard.

Do not be alarmed however, the crunch or popping sound is rather loud and resembles the same kind of crunch when installing a new Intel processor into a new motherboard, only much, much louder.

Step 7 – Safely Removing the Screw from The Tool

Once the ‘hard’ part has been completed, removing the threaded screw safely is as important as it was installing. When removing the screw, it’s a good idea to angle the screw as in the image and ensure your have two hands available when removing the screw. The best way to achieve this is loosen the bolt by using the Allen key until it’s loose enough to screw by hands. The consequence of losing grip on the bolt while removing it could result in pin damage don’t want the end of the screw to scrape or even touch the pins.

Step 8 – Checking the Delid Was Successful

If all the steps have been followed correctly, the result should be a clear one, a freshly delidded Ryzen 3 2200G or Ryzen 5 2400G APU. With the aluminum Die Mate 2 block removed and the adapter, the chip itself should be loose from the IHS and should be ambulatory.

Now that the Ryzen 5 2400G has been successfully delidded without any damage, it’s now time to prepare it for use on the test bench to see what/if there are any thermal benefits, as well as available overclocking headroom as a result of this process.

    Heatsink mounts are height sensitive. If you reduce the net CPU height then you can reduce, or even totally eliminate, the downforce on the CPU, which is not good! Direct contact between the CPU and heatsink is always going to be preferable, because it reduces the thermal resistance. If it's not possible to achieve the proper downforce, then use a small metal shim rather than using the original heat spreader. Probably most any metal shim would do, but it's going to need some kind of heat-transfer compound. It should be the same thickness as the original heat spreader and cut to the size of the CPU and perfectly flat. Removing the original heat spreader brings the added benefit of convection cooling for the other little chips surrounding the CPU.

    I’m skeptical. I’ve dealt with a lot of cpu mounts and I doubt the spring loading will notice 1mm difference. Heck a lot of them load the springs with screws and there’s going to be a wide variance there based on how hard people torque the screws.

    Heatsink mounts are height sensitive, NOT.

    Tests like the POV-Ray results are nice because they show not all "stable" overclocks produce the same performance results, even at the same clockspeed.

    Gavin, I like your writing style and enjoyed the article. I look forward to reading more from you in the future.

    I don't know if it actually helps or not but in the case of switching my laptop CPU to liquid metal I followed the LTT recommended method and applied some conformal coating to the area around the die, two layers especially covering the visible passive components on the chip. Supposedly this helps protect it in case any LM does come out and contact it. Haven't had any of the laptops I've done this to fry yet, thankfully.

    also this stuff looks incredible, photos from my first application on a 5th gen i5 u series processor:

    a little drop goes a long way, you can see I probably had too much here.
  • SilthDraeth - Sunday, May 13, 2018 - link

    Do you actually have to reinstall the IHS? Or could you simply install the heatsink directly to the processor like days of old?
  • none12345 - Tuesday, May 15, 2018 - link

    Please no one actually delid a 2400g, you would be wasting your money.

    $78 dollars worth of tools and paste. And a $180 cooler.....all to make a $170 chip lose a few degrees at load and not overclock any fruther...

    Please spend $260 somewhere else. 260+170 for the 2400g is enough to buy yourself a 2600 and still have $230 for a gpu(which before the mining craze would get you a 580 8gb/1060 6gb). Which would run absolute circles arround a delided 2400g.
