RAM is becoming more expensive
At the beginning of June you got 64 MB RAM for 120 DM. With the 128 modules, the increase is not quite as strong compared to June, but with 330 DM you have to pay much more here (at the beginning of June 250 DM).
Experts even expect prices to rise even further. The reasons for this are the continued high demand for PCs and the high utilization of the production facilities at the memory chip manufacturers.
