The Apacer memory modules we tested, produced very good overall performance. At 533MHz and 667MHz, the modules are comparable in performance to OCZ's PC5300.
According to our tests, Apacer's memory modules proved to be about equal to the OCZ PC5300 modules we have reviewed in the past, but any differences were negligible.
With SiSoftware Sandra 2005, OCZ showed marginally better performance while with PCMark05, the honours were divided. PassMark reported slightly better results for the OCZ modules while in Half Life 2, the performance was the same for both memory sets.
Don't expect performance above 667MHz. To be honest, going on past experience with the previous Apacer memory we tested, where the certified 533MHz PC4300 modules could run at 690MHz, we expected to see something better than 674MHz. Above this frequency, Memtest86+ reported either errors or our test PC froze.
On the e-market, it is not to easy to locate Apacer's memory modules, something we also highlighted in our previous Apacer memory review. Prices are around $210 in the US and close to €185 in the Europe, including VAT for Apacer 2X512MB DDR2 PC5300 667MHz modules.
