Which to have? at a ratio of 5:4 will the Mushkin Black 512MB PC3200 stop me from getting the chips max overclock? 2.4c

there's not a really big difference between the Black Level 2 PC3200 & PC3500. Both use the same PCB and same Winbond BH-5 Chips. The PC3500 is just guaranteed to hit 217mhz, but you can almost always easily hit that with the PC3200.

Ideally, they only need to be identical in size. You are going to want to get two identical modules that, at the very least, share identical specifications and ICs. Buying two of the same modules, or even better, a Dual Channel kit, will save you unnecesary grief of having one module underperform the other.
Answer:Why does dual channel impact Intel Chips more than AMD?
Intel is quad pumped ..AMD is just dually...
Now, for the platform dependant part. Think of a highway yet again, this time an 4 lane wide one, representing a dual channel DDR configuration. Now suppose that highway comes up to a bridge. If that bridge is also 4 lanes across, then there is no choking off of the data, it can all ramp smoothly onto and over the bridge. This is what occurs in an Intel Pentium 4 configuration. That bridge is the FSB. Because a P4's FSB is "quad pumped" for data (it's only "double pumped" for addresses though, which are much shorter), it is capable of bringing all that data from the 128bit channels right in. What "quad pumped" means, is very similar to the DDR improvements I mentioned earlier. Only this time, data is sent twice on the rising and falling edges. Pretend the signal voltage is 1.5V. When the voltage reaches 0.7V, data is sent, and again when 1.5V is reached. On the down slope, the same thing occurs, data sent at 0.7V and 0V. This explains why the P4 architecture is such a bandwidth hog. When using a single memory controller configuration, like the i845 chipset, or a i865/i875 with only one channel being used, the FSB is capable of sending much more data than the memory controller can bring in from the ram, causing inefficiency.

Dual channel will give me same overclock as none?
