The overall performance for both memory sets was good if we keep in mind that we are dealing with inexpensive DDR2 solutions. The fact that both sets were capable of running at 690MHz is rather good, especially for the Apacer modules which had lower timings and higher bandwidth, according to Memtest86+. The Apacer modules managed to retain the 4-4-4-11 at 693MHz while the Transcend had to be decreased to 5-5-5-15. The highest bandwidth with Memtest86+ was 3710MHz for the Apacer at 693MHz, and 3425MHz for the Transcend when running at 654MHz.
According to our tests, Apacer proved to be better and faster than Transcend no matter what the speed was. SiSoft Sandra 2005, PCMark04 reported higher performance for the Apacer while in PerformanceTest v5.0, Apacer was faster at both read and write than Transcend. In games, the overclocked CPU in combination with the increased memory speed raised the performance, which one more time was slightly better with the Apacer modules. On the other hand, with Transcend modules installed, the CPU was slightly better when operating at limits.
At e-market, it is much easier to locate Transcend's memory modules than Apacer's. Prices are around US$45 for the Transcend 512MB module while the same module from Apacer costs approximately US$55.
