AMD delid - Anyone done it before? (2400G)

[Emlyn_Dewar]

I've got a 2400G that clearly has some issue with the heat spreader/CPU die contact. The temperature is always way too high. Paste application, and even different coolers are achieving nothing. I swapped out to a 1700X and it's way cooler, but obviously this isn't ideal as it's not got a iGPU.

I've delidded some Skylake CPUs before, but never done an AMD one. Has anyone tried it before? Looks like I just need a 3d printed shim for my existing tool to get it done. I'm just worried about the pins.

The 2400G doesn't get that hot, so if your IHS is knackered to the extent no cooler makes proper contact I'd be inclined to lap it instead of delidding. AMD solder their IHS instead of using toothpaste.

Tell that to the 78 degrees peak temperature today. It makes no difference over 3 coolers, including the stock cooler. Running at stock...
Most AMD CPUs are soldered. These ones aren't though (are any of the newer APUs?). It rockets up to high temps, just as I've witnessed from older 6th gen CPUs.

I'll ask the seller that I got the delid tool from if they've got extras. I don't really want to do it, but I think there's no other hope for this CPU. In fairness to it, it's still running stuff, I just need to get some consistent temps.

 

[Emlyn_Dewar]

Yeah, I didn't mind it on the Intels because they're LGA. More worried on the AMD because there's a lot of pins to potentially crush.

 

[Emlyn_Dewar]

Not for me! Maybe if it was a 7000 series AMD I'd be alright with it, but a 2400G shouldn't be seeing this.
It's also how it gets to that temperature. It's not a gradual rise, just shoots up there when there's load placed on it. I could maybe understand it with the stock cooler, but with a chunky tower cooler on it's the same behaviour. Higher temps lead to higher fan RPM, but no additional cooling achieved.

Well, I ignored the delid tool and just used a razor blade. I took a long time to get through the glue stuff on each side, as I saw a few scare stories of people knocking off some of the surface mount components... My patience paid off and I have not knocked any off, so hopefully all will be good.
Amusingly, I actually sold the board with the 1700X in it this week, as it was a good way to clear out some spare parts as a full system. So now I have nothing to test the 2400G out in... I'll be sorting out a replacement board and some liquid metal soon enough. Will report back here with findings when they arrive. Pins and CPU still look good to my eyes, so it should still work, just far more nervous doing this with an AMD CPU even if it is crappy and old at this stage!

Edit: As an update to this. The black glue holding the heatspreader on, is way way more of a hassle to get of than on an Intel CPU.

Not worth the time and effort, you'll get more performance just buying a new gen chip they go for very little now and typically just drop into old boards. 4xxxG (Zen 2) and 5xxxG (Zen 3)

This chip offers enough for what I was using it for. I guess I gave it an hour of time, including glue removal yesterday. Not a big deal, especially given I'm on holiday at the moment. With an OC on the GPU, there is very little graphics performance gained on the newer AM4 APUs. A shame there was never an RDNA2/3 chip for the board.

So I got back from a few days away and had a cheap AX370M-DS3H and Kingston DDR4 delivered. I went for a MATX board as I had a ZZAW C2 from another build I’d been wanting to use. It’s a smaller case than the CPU was in before, with next to know airflow.
Even with the different case, the difference in temperatures after the delid is insane. The cooler on at the moment is an ID-Cooling IS-50X, and at stock after 20 of Heaven benchmark it had a max temperature of 53 degrees. Previously it would been over 70 after a minute of this!
Time to get an OC back on the GPU and see what this memory will clock to.

I really can’t see me ever knowingly buying a non-soldered IHS CPU in the future, as they’re just ticking time-bombs. Does feel quite good to get the temps back to where they belong though.
