DDR3 Rank 1 vs Rank 2 ? ? ?

post #1 of 6
Thread Starter 
I have 2 kingston rams

slot # 1: kvr1333d3s8n9/2g

slot # 2: kvr1333d3n9/2g-sp

One of em has rank 1 and the other rank 2 ......

Whats the difference between 2 ? ? ?

Can they pose a problem when overclocking My CPU ? ? ?

They are working perfectly fine on stock CPU !

Sorry, what do you mean by rank 1 and rank 2? Are you talking about the timings or something?

Ranks: http://en.wikipedia.org/wiki/DDR_SDRAM

To increase memory capacity and bandwidth, chips are combined on a module. For instance, the 64-bit data bus for DIMM requires eight 8-bit chips, addressed in parallel. Multiple chips with the common address lines are called a memory rank. The term was introduced to avoid confusion with chip internal rows and banks. A memory module may bear more than one rank. The term sides would also be confusing because it incorrectly suggests the physical placement of chips on the module.
All ranks are connected to the same memory bus (address+data). The Chip Select signal is used to issue commands to specific rank.
Adding modules to the single memory bus creates additional electrical load on its drivers. To mitigate the resulting bus signaling rate drop and overcome the memory bottleneck, new chipsets employ the multi-channel architecture.

Simply which is better for gaming ? ? ? ? ? i know a\the difference is little but which one ??

As the have different ranks can the pose a problem in overclocking cpu ???

I wouldn't have thought it would cause a big issue, however using different sets of memory together is never recommended.
