Can I put DDR2 PC6400 memory in a desktop spec'd for DDR2 PC3200?

[bsi]

I have an old HP D330 with 512M. The manual says it takes DDR2 PC3200 but I suspect that was only the case at the time the manual was created.

Newer memory in the DDR2 configuration is more available and cheaper. Can I buy, say PC6400 and put it in this machine? I don't plan to leave the existing memory in there. I don't care if the new memory runs slower than it could, I just want more of it.

No ...... the older ram is harder to find thus more expensive. you can go down to slower speed ram but not up to faster ram on an older system.

I think the reverse is true. IE YES you can use PC2-6400 to replace PC2-3200. Wikipedia says: "Higher performance DDR2 DIMMs are compatible with lower performance DDR2 DIMMs; however, the higher performance module runs at the lower module's frequency. Using lower performing DDR2 memory in a system capable of higher performance results in the bus running at the rate of the lowest performance memory in use; however, in many systems this performance hit can be mitigated to some extent by setting the timings of the memory to a lower latency setting.

Well... this is what I want to hear So, no voltage issue?

BTW, great link to Kingston.

Or just buy the correct memory... http://www.canadacomputers.com/index.php?cPath=24_311_313_618

Hmm, was not seeing that price anywhere. Everyone who had it in stock wanted $70/1G.
