nForce underclocks the memory

Many people will probably think that the nForce chipset is very quick to deal with memory. But this is not the case. With a feature, as it is called by nVidia, the memory can be slowed down under certain circumstances.

The nForce 420 chipset from nVidia slows down the memory under certain circumstances. This 'problem' or feature, occurs when a 'doublesided RAM module' is pushed into the second or third memory bank. The chipset has a twin-bank memory system, or in other words a dual-channel DDR RAM system, but the performance can drop drastically with the above equipment. With GamePC , only 680 MB/s was measured instead of the normal 910 MB/s. According to nVidia, this function is there to keep systems with problematic memory stable. The 'Superstability Mode' clocks the memory down to 100 MHz and increases the timing. You can set what you want in the BIOS, nothing will change. nVidia calls it a 'feature', but it is more likely that the memory channels were not synchronized correctly. Since most of the memory modules sold are 'doublesided', many users will probably have to be satisfied with poorer performance.
