lost a few hours yesterday to some hp & lenovo and amd & intel memory bus nightmares started when i tried swapping DDR3 / PC3 / PC3L ram between an HP and two LENOVO notebooks
- HP 255 G2 with AMD A4 memory bus FIXED at 1600Mhz
- Lenovo T410 with Core i5 memory bus ONLY works at 1333Mhz
- Lenovo Z50 with AMD FX7500 memory bus FIXED at 800Mhz
Basically the T41o refused to work with any of the other memory whereas i thought DDR3 ram was downwards compatible.
Actually just looking at my photos maybe PC3L is not downwards compatible with PC3 ?
