memory heat spreaders a gimmick?


Most high end users claim that for overclocking of your random access memory module, it is imperative to keep it cool. After all we are pushing the stick to the edge, trying to work for us at maximum efficiency. The other side of it,I’ve a;ways wondered if that were true,or was it simply a way to disguise the PCB and memory chips of the module,with a shiny colored jacket,thus also serving as an advertisement  placard for the manufacturer.We decided to test, and ordered 25 pieces to satisfy our curiosity.I might add, the customs,duty and freight, cost us more than the price of the memory heat spreaders itself!

That’s what it looked like.

The outside shield felt cold,it was aluminium bodied,with the inside being a high conductivity adhesive tape, that stuck right on the memory chips. We pulled together a group of friends armed with copper leads, digital thermometer, thermal paste.Now testing on a 2GB.DDR3,1333MHZ module that was working since 2 hours, we got it working till physical memory was used up to the max.Temperature recorded was  57 C.Now with the random access memory Heat spreader,under the same conditions gave us a reading of 46C.

So it  did work,albeit not asmuch as it claimed to be.

Some of the feature that were highlighted on the pack were:

 Reduces the temperature by about 35%,great for performance of overclocked systems.

It didn’t make much difference to system performance in any way,and maybe alittle to get the temperature down.

The primary objective was to dissipate the heat laterally. Most other memory manufacturers have them,and they all look good,bright red and blue,thyre quite attractive,but as far efficiency is concerned,id say people could do without it,because for example I spoke to a friend of mine who worked at a major  OEM memory manufacturing factory  from Hongkong and she didn’t even know,what those shiny things were!
So next time you go out to buy a random access memory heat spreader,think again!
