It is a disappointment when faster memory has to be slowed down because those extra two sticks you bought on ebay at a good price, are of a slightly lower spec. Some MoBos are more tolerant than others. I have had systems which failed to work when the additional RAM modules were not part of a matching kit. I've had others which would work no matter what you threw at them. High performance MoBos which have highly strung specs, tend to require lowering frequency/increasing latency when you add more RAM. Regarding Dale's question, which has already been answered - yes, anything the bad memory has touched is suspect of corruption. Without ECC RAM a dodgy module can cause a lot of damage before it is discovered. This is why I *always* run memtest86+ overnight whenever I get a new system, or add new RAM. I've only had one fail over the years, but I'd better be safe than sorry. ;-) --nextPart3641387.R56niFO833 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part.
