How do I know if my RAM is single or dual rank?
Herein, how do I know if my RAM is dual rank?
How do I tell the difference between dual and single rank modules? Multiply total number of chips (less any ECC chips) by the chip width. If it equals 64 its single rank. If it equals 128 its dual rank.
Also asked, should I buy single or dual rank RAM?
Generally Single Rank Memory is faster than Dual Rank Memory, in layman's terms when a computer accesses Single Rank Memory it only has to go around the track once, where are Dual Rank it would have to go around the track twice.
A = 1Rx8 means the memory chips are on one side of the RAM module and 2Rx8 means the memory chips are on both sides of the RAM module. On the other hand using a PC3L RAM in a PC3 RAM slot may damage it due to overvoltage. So PC3 and PC3L RAMs are not compatible with each other.
