Bandwidth at 1066Mhz DDR

Let's have a new look at Sandra's bandwidth test, now with the 1066Mhz memory strap. In these graphs, the PC6400 kits from OCZ and Kingston are omitted as these couldn't perform at 1066Mhz DDR.

In all our graphs, please look at the blue bars for the PC8500 kit. The bar for best performing memory in each test is coloured yellow.



Because our Kingston PC8500 memory has to operate at a cas 5 setting at 1066Mhz, whereas the other Micron kits were able to operate at cas 4, we get about 80Mb/s less bandwidth from Kingston in regard to the other kits.

Latency at 1066Mhz DDR

A renewed look at Everest now :



Here the same conclusion can be made as with the bandwidth test : the higher cas setting of the Kingston memory makes it fall behind a little in comparison to the other kits.

Benchmarks at 1066Mhz settings

First up is 3D Mark 2001 again :



3D Mark 2001 is strongly affected by cpu performance, and the cas 5 performance of the Kingston PC8500 kit versus the cas 4 performance from the other high end kits costs Kingston 80 to 120 marks in the end result. Next up is 3D Mark 2006 :



Again, some cpu marks are lost because of the higher cas setting, but the differences are way to small to be noticed. Also watch the total scores, where the Kingston is not the worst performer of the pack.



As with the 800Mhz setting, PC Mark 2005 seems to favor our Kingston kit a little more. The PC8500 is in the middle of the pack here.

Time for our video encoding test :



Cinebench is again not influenced by the higher memory speeds. Real world performance does not change over the 800Mhz setting. Now for some Superpi :



In Superpi performance the higher cas rating can be noticed. When you absolutely have to have the fastest pi score, Kingston might not be your first choice, but then again : differences are small, very small. A better tweaked windows installation will do a lot more to improve your score...

Finally : time for some game tests :



A very good showing here in the first Prey game test, in the second game test our kit finishes at the back of the pack.



In F.E.A.R., again a very good score is obtained: Kingston is in the middle of the pack here, even with a slower cas rating.
