Memory modules from Corsair are available worldwide as a rule, whereas Infineon and TakeMS are mainly prevalent in Europe. In practice the purchase of two DIMM modules is a sensible option, with 1 GB RAM in total, as modules with larger capacities than 512 MB are still expensive.

We consciously used a branded memory, which does not however support any extremely fast timings - these can scarcely be maintained if two memory modules are used.

Acid Test With Prime95

Prime95 is a small program used to search for prime numbers. The arithmetic operations which this process involves make an ideal stability test for many computers. The developers have envisaged three test methods for this (see picture above). We opted for the memory test of course.

If the test unit from Prime 95 is run, the result should look something like this.

Detected calculation errors lead to the torture test being aborted. Unfortunately, this happened to us on several occasions during our memory test.
