X1 (very first gen, NOT Carbon/Extreme/Yoga) RAM

#1 Post by RealBlackStuff » Fri Feb 19, 2021 6:47 am

I just received a new 8GB RAM-module for the X1 Type 1294 (made in 2012).
This is the original first X1, precursor to Carbon/Extreme/Yoga.
This X1 runs fine on 1.5V DDR3/PC3 memory, but they sent me 1.35V DDR3L-1333/PC3L-10600s.
Before I open it, does anyone know if this will work OK in there, or if it will run hot, or if it will NOT work?
AFAIK DDR3L only works from 3rd gen CPU onward, the X1 has 2nd gen i5-2520M CPU.
Still NOT a great day for a Guinness! (the Real Black Stuff).

36 views, amazed that nobody reacted.
Anyway, I just tried a DDR3L-1600 module from my T440p in that X1, and it worked!
Thus I unpacked the new DDR3L-1333, put it in, and that works as well!
So Intel's info on the web about Gen2 (=Sandy Bridge) CPUs is wrong, 1.35V DDR3L works there also.

I have an 8GB DDR3L-1600 stick in my X220 working with no issues. What I do know is that the X220 runs it at standard DDR3 voltage of 1.5v rather than 1.35v.

There's one guy online that modded his X220 to supply 1.45v to the RAM slots because 1.5v caused his DDR3L sticks to overheat and glitch occasionally.
Daily driver: X220 4291-C91 i7-2620M

Backup: X601 Core 2 Duo T8100
Toy: X60F Core Solo U1300
On loan: X220 4291-P79 i5-2520M
In pieces: two retired but working X61Ts
RIP: 760XD 9546-U9E; X61 7676-A24; and a BOE-Hydis HV121P01-100 in failed SXGA+ mod
