Basic(newbie) question

When you want to find out the max FSB a DDR3 memory can handle you divide its speed by 4 or 2?

Divide by 2 for Intel CPUs. So DDR3 1600, if going for a 1:1 ratio, will allow for a 800Mhz FSB.

The overclocking guide is wrong then?

• The first part is self-explanatory (DDR3 memory).
• The number after it is the data transfer rate. Simply divide it by 4 to get the maximum FSB speed for which the module is rated. Example: 1600/4 = 400 MHz. Therefore, DDR3-1600 can work on systems with a FSB of up to 400 MHz (anything more and you’re lucky).
• The PC3-XXXXX is designation denoting theoretical bandwidth in MB/s. Some memory manufactures use this instead of the DDR3-xxxx designation. You can calculate it for any FSB you want by simply taking the FSB and multiplying by 32 (rounded in some cases). Example using a 400 MHz FSB: 400x32=12800. So you’d need at least PC3-12800 to run on FSB of 400 MHz.

Someone should fix that

I think it's wrong.
