Apacer is a well known manufacturer of RAM modules world-wide. These are the first memory modules that can actually run at 500MHz. However, you should be aware that there are some compatibility problems with some motherboards. This in most cases is a matter of a BIOS update, so, every motherboard manufacturer is now working to provide updates that support 500MHz running frequencies. We tested the Apacer Real500 2x512MB and we have mixed thoughts about this memory.

First of all, the comparison with the Corsair XMS 3200XL memory proved a fitting challenge. The Corsair memory is one of the fastest memories around and it is not easy to compete with the kind of speed performance offered by Corsair. The default speed value we got with the Abit AN8 Fatal1ty was 400MHz (2x200MHz, dual channel), and we decided to stay with this frequency in our standard tests, since most users will not want to fool around with their BIOS settings.

Performance at this speed was satisfactory and in all tests, the Corsair memory was slightly faster than Apacer. However, when we tweaked the Real500s up to 500MHz, Corsair was outgunned. The performance difference between Corsair (400MHz) and Apacer (500MHz) was now evident.

The Apacer Real500 PC4000 are priced at around €60 per module, which is a very good price.

The Good:
- Excellent performance at 500MHz
- Cool operation
- Very good price

The Bad:
- Average performance at 400MHz
- Must interfere with the BIOS settings to get 500MHz operating frequency
