Yes, not only can you read them, on many systems you can write to them too.

I used this to re-program some SDRAM after adding parity chips to them.

Note that there is a write-protect pin on the DIMMs that motherboards are supposed to activate to prevent writing in a system (i.e. so that a virus does not trash your DIMMs) but none of the systems I have tested on actually implement this.

Ein Hoch auf unsere Hardware Industrie. Wie einfach man nen Rechner damit niederstrecken kann …. Eine Boot CD/Memstick reicht um hardware unbrauchbar zu machen.
