Our test setup hasn't changed from the previous reviews, have a look :
As we explained in our previous
reviews, the "Generic PC4300" module is a 533Mhz part with quite basic timings, at the time of writing. This "Generic" module does not really exist: we constructed this module with the Corsair Dominator modules, but slowed the modules down to 533 Mhz DDR with (relatively) slow timings. The timings we "arranged" are 4-4-4-15 timings. You might wonder why we chose exactly this speed and these timings. We could have picked an even slower part with PC3200 speeds or 5-5-5 timings, but than again, these modules are barely available anymore. The cheapest memory kits you can find nowadays are almost all capable of doing 533Mhz with 4-4-4 timings, so in our opinion, this seemed like a nice performance base to compare our memory kits with.Test methodology
Every module we test, except for the above mentioned generic module, was put to the test at five different speeds:PC6400 - 800Mhz performance, at the best possible timings
PC8500 - 1066Mhz performance, at the best possible timings*
Maximum cas 3 performance
Maximum cas 4 performance
Maximum cas 5 performance
*1066 Mhz is tested only for the modules for which this is possible, in this case all the modules were capable of reaching this speed, except for the PC6400 kits from OCZ and Kingston. These PC6400 kits are omitted in the DDR1066 table.
For the 800Mhz and 1066Mhz tests, settings are very simple: in bios only the memory speed was turned up to the appropriate setting, while front side bus (FSB) and cpu speed (and multiplier) remained at the stock settings of 266FSB and 2.66Ghz respectively.
The maximum cas "x" performance is measured at other than stock cpu and FSB settings, to be able to give the memory sufficient bandwidth, and to play down the influence of the cpu in comparison to the memory. In our tables on page 6 you'll see that the cpu speeds and FSB setting is always mentioned at the bottom, so please bare that in mind when comparing the results. So to be clear: results cannot be directly compared, as the cpu/Fsb factor accounts for a certain % of the performance shown.
For the cas 3 setting we test with a CPU multiplier of 9, and a memory divider of 4:5 or 667Mhz in bios. For the cas 4 and 5 setting we test with an CPU multiplier of 8, and a memory divider of 2:3 or 800Mhz.
Onto the overclocking fun ->
