Defective RAM?

Trying to upgrade a laptop from 16GB to 64GB. The stock RAM is 2x8GB DDR5-5600 (generic brand as far as I can see). I have a set of Crucial 2X32GB DDR5-4800 from an older laptop. When I swap it in, the laptop will not power up. No sign of life whatsoever. I thought maybe I killed it somehow, but placing the original RAM back in, it works as normal. I've repeated this experiment 3 times now with the same exact result.

I have no other device that takes DDR5 SODIMMs, so I can't test the Crucial 64GB kit. But it was a working pull so hard to believe it is a problem. Also, I figured an incompatible RAM would at least try to start up and fail POST or something. This doesn't even give me a single LED showing it is even trying to boot at all.

What could be happening here? Any ideas?
 
The specs might be wrong, though. I have laptops that run with more RAM than the manufacturer specified as max.

OP, you are screwed.
 
The laptop supports up to 96GB officially, and I've read reports of people going to 128GB successfully. So should be good to go.

I guess my general questions pertains to the complete lack of any sign of life. Let's say it only supported 32GB total (which would be weird but let's say hypothetically) - wouldn't it still try to boot and then not proceed past a certain point? Same thing for a situation where one or even both sticks are bad. It seems like it would at least try to start up. That's always been my experience with desktop builds, though I haven't tinkered with enough laptops to know what to expect.

I guess my next step is to retry with only one of the 32GB sticks at a time, to see if that changes anything.

EDIT the training thing should only take a minute or two at most right? And the various power LEDs should come on, basically some signs of life even while it works through that process. In my case there is no response to the power button, no LED or fan spin or anything else. Completely dead. So I doubt training has anything to do with it.

I would give that a go for sure.

That can change per plaform/BIOS. AMD or Intel CPU?
 
FWIW, I had a defective Kingston 8gb ddr4 that if installed, nothing would happen when power button is pressed. Nothing, not even a beep, a boot to bios, nothing. When defective stick was moved to a confirmed working mini PC, that mini PC became unresponsive.

Interesting, thank you for that. Perhaps that's what happened here. I'll swap them individually and see if I can at least salvage one of them.

It's an MSI with a Ryzen 9 8940HX.

I have seen some Ryzen systems take a LONG time to train. Once you try one stick to see if you can confirm that it is good, I would put both in and power it up and go have lunch. See what happens. Will not hurt anything.

That's the thing, it doesn't look like is even trying to power up. Press power button, or hold it down for a while, wait 10 minutes, nothing happens.

Wouldn't the training process involve some signs of life? I would think the CPU is running so it needs the cooling system active and so on.
 
yeah, see if there is a bios update, one of those "fixes compatibility" ones.
then one stick at a time, see if you can get it to power up.
