crwdns2890332:0Can I use PC3L 12800S RAM in place of PC3 10600S RAMcrwdne2890332:0The answer, unfortunately is not definitive. Usually, yes. But, because of no strict standardization enforcement it may not work. I’d say better to order DDR3 if that is what originally came with your motherboard. I bought 3 PC3L RAM different brands all did not work on my PC3 system.
