The OCZ 3500 sticks are capable of some decent speeds, all the while doing them at excellent timings They're bit hard to justify for ordinary Athlon users, but FSB overclockers will like the extra headroom. These sticks are best suited in P4 system, though. Using a 1.6 RAM:FSB ratio, the 3500 modules can take a P4 over 3.1GHz, and a 2.6 to almost 3.4Ghz (assuming your board can handle the FSB speeds [260+], and the CPU is willing to go that far), all with tight timings. Unless your going for a more extreme overclock, the 3500 modules are unlikely to be a bottleneck in your system.
