Lower latencies allow for higher overclocking in general. The lower they come default, the better. But, since you have a 2500+ Barton, and since about week 40-something or so, they've had a locked multiplier (unless we're talking a Mobile Barton 2500+), you'll have to get some seriously newer RAM in order to increase the FSB on your CPU. Because that's where the real overclocking is at. If you only have RAM that's clocked at 333 Mhz, your CPU is really, really restrained on OC'ing. I mean, majorly. I only know this because me and Lasereth tried it with Redjake's PC, and he had some genericore PC2700 RAM in there, and well, we got it to about 1.88 GHz, and that was about as far as she went without completely locking before you could get to Windows. So, yeah, I would definitely suggest some good PC3200 RAM, we're talking your Crucial or some nice Kingston, like some
Kingston Hyper X 184 Pin 512MB DDR PC-3200. That shiz has a nice, low, stock latency, at 2-3-2-6. Not bad for stock, but, with the proper cooling, you can do better.
