Thinkpad P51 doesn't boot with upgraded memory

Hi all,

 

Just bought brand new Thinkpad P51 (20hh0014rt).

 

All latest software updates installed.

Now I'm trying to upgrade memory and installing Kingston HyperX HX424S14IBK2/32 kit of 2 x 16Gb in to the slots under the bottom cover - my notebook doesn't boot in this configuration (I press ON button, I can see power LED is on and hear the cooling system, but nothing happens...)

When I remove this two memory modules - notebook bootup without problems.

 

This modules are ok at 200% - I'm writing this right now at my Thinkpad P470 with both those modules installed.

 

Is there any way of how I can use this memory with my P51?

 

Thanks!

If the modules work in a T470, the memory type is DDR4-2133.

 

The P51 uses DDR4-2400.

This is not true.

Kingston HyperX HX424S14IBK2/32 is DDR4-2400 (proof).

T470 (so as P51 I'm sure) support both.

Do you hear a beep code when you try to start?  If so and you have an Android device use the Lenovo Diagnotistics App.

P51 - Xeon E3 1505M v6, FHD, 32 GB (2x16) 2400 MHz Crucial ECC, Quadro M2200, 500 GB Samsung 960 EVO NVMe, 500 GB WD Black

No, there are no any beep codes.

 

Sympthoms looks like described in this topic: https://forums.lenovo.com/t5/ThinkPad-P-and-W-Series-Mobile/Thinkpad-P50-does-not-boot/td-p/2252061

Finally I found the solution (looking odd, but works!).

 

Actially this idea is from this message: https://forums.lenovo.com/t5/ThinkPad-P-and-W-Series-Mobile/Thinkpad-P50-does-not-boot/m-p/3482765#M...

 

So I just put my new Kingston modules in the slots under the keyboard and factory installed 8Gb Samsung to the slot under the bottom cover and VIOLA! It works now!

 

Hope this helps.
