RAM Performance - Single Side vs Double Side

[UaVaj]

single module, same size, same specs.

simply
8 chip (single side)
vs
16 chip (double side)

is there any performance difference? for memory controller? for max overclock? for temperature? for anything else?

nah

Check your MB memory configuration options (in the manual).
Some configurations may not work together.

Your question is hard to answer, because you need to get into the Memory Geometry and Ranks concept, and the amount of Chips (8 or 16) doesn't tells you that. So you have no way to know what they really are without going a bit to deep. I discovered that when looking at some articles that claimed that AMD Kaveri received a performance boost if running Dual Rank modules.

take a look here

The highly clocked MFR-based kits are not slower because of the memory timings, but mainly because they are single sided.
As you can see, a DDR3-2933C11 MFR memory kit is slower than a DDR3-2400C11(!) kit. That is nothing short of sad.

cant find it now but i have also seen where somebody sent there double sided 2400 ram kit of for rma and got back a single sided kit which performed below there old ram when set at 1866mhz
at least thats how i remember it...

guess its possible that its due to something other than being single sided like sub timings

If I remember correctly from my AMD days, at the same frequency, a dual rank DIMM may be able to achieve higher throughput due to interleaving.

But, single rank should in theory support a higher frequency so there is some trade-off there.

you guys are making this harder than it is.
please keep it simple.

4GB single module with exact same specs (i.e. DDR3 PC2400 CL10). only difference is configuration (aka chip size and chip number).

single side configuration is 512MB x8
double side configuration is 256MB x16

just want to see if anyone else had the same experience.

"Generally Single Rank Memory is faster than Dual Rank Memory, in laymen’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."
