Please advise how to "upgrade the RAM", properly, for Thinkpad T480:
I got the machine in March 2018, and things were working right out of the box: I pop in my old SSD (re-imaged) and my old RAMs (32G) from T470, and everything was working back then.
Last Thursday, IBM kindly replaced my mother board to fix an issue with a set of three docking stations: none of the USB ports on the docks worked. After the motherboard replacement, I see Blue Screen every other 10 minutes or so.
It started as showing Blue Screen only when I pop the laptop from the dock; then, after the kind suggestions to change BIOS setting (disabling a set of Display + Thunderbolt settings), I am welcomed by the Blue Screen every 10 minutes or so.
Upon a third call to Thinkpad Premier support, I was told to throw away those 32GB of RAM, and go with the Lenovo RAM (8GB). It should have stopped the Blue Screen from popping up anymore. I don't get the rationale behind this, and I also would like to perform a RAM upgrade.
In short, Lenovo is selling 8GB of ram (another one) at 200+ USD. Again, I cannot make sense from this either.
Please advise what specification of RAM should I buy
Previously, my 32GB OWC RAMs are working well for my T470 and T480. I bought it from here.
Specification for the pair of RAM that fails on the new Mother Board:
32.0GB (2 x 16.0GB) 2400MHZ DDR4 SO-DIMM PC4-19200 260 Pin CL17
Here goes the specs for the 8GB RAM that I got out of the box, from Lenovo:
Samsung 8GB DDR4 PC4-19200, 2400MHz, 260 PIN SODIMM, CL 17, 1.2V, ram memory module, M471A1K43BB1-CRC
