On a laptop maybe. On a desktop, the air around the RAM modules get maybe 1 degree C warmer (I know because I have temp sensor there, connected to the front panel). When it does get warm is when there's GPU and disk load. Those suckers combined can raise the temp inside the box by 5-6 degrees. The meaning of all this is that if memtest can't find any errors after a full run (which can take an hour), the chances of getting an error that is really related to RAM under CPU stress are very slim.
