So I'm looking at DDR2 Ram for my new PC. I've possibly settled on DDR2 800 but my question is how much difference do the timings make? Right now I'm comparing these 3 sets of ram:

The first 2 have 4-4-4-12, the last having 4-5-4-15. How much does this really matter? I've read that OCZ ram is very overclockable, so would it be worth paying a little less for the memory and overclocking it to better timings and faster speed? Also, what does ECC mean/matter? What is EPP (Enhanced Performance Profiles)? And why does ram have to be SLI certified? Or does it really? TY for input/knowledge.

From reading the reviews about the OCZ ram I'm not going to get it. Seems like too many people have had to RMA it, and 2 people specified it doesn't work with the mobo I'm considering. Still any info to my above questions would be appreciated. Thanks.
