I would like to upgrade my X201i RAM to 2x 4GB. I already tried second pair of memory chips, but I always get the same result: memory is recognized in BIOS, memtest86 fails after few seconds and reboots and booting OS also fails.
I tried unsuccessfully following chips:
Quicker Crucial chip should theoretically slow down to the required speed, but it apparently did not so. Lenovo memory compatibility info for X201i explicitly suggests PC3-10600 DDR3-1333.
What could be wrong? Can anyone post his 8 GB setup?

I have a Intel Core i3 M 370, the CPU supports 8 GB max.
I tested both sets of RAM with 32-bit Ubuntu and Memtest86. I know about differences between 32-bit and 64-bit OS and I installed 64-bit Fedora Linux meanwhile.

so what was the original shipped ram configuration? At this moment, i can only suggest trying to get 4 gigs of 1066 mhz DDR3 ram or something.

I got 1 + 2GB PC3-8500-CL7 / 1066 (FRU 55Y3713 and FRU 55Y3712) now. I'll test the PC3-8500 / 1066 chips. Unfortunately they are more expensive than the quicker ones.
What is really confusing is the Lenovo memory compatibility page, which states that PC3-10600 DDR3-1333 is ok for X201i.
