haha... Kyle, guess you had to through the ignorant thing back in my face... of course I intended to mean devoid of knowledge, not that anyone is stupid.
The 1.6A is a year 2002 Generation P4 w/ 512k cache. Similar to the Celeron 300A... remember that one on the 440BX chipset, ringing any bells. Anyway, the 1.6A was the first chip which I was ever able to push upwards of 50% OC. All other overclocks, at least for me, were modest. Typically toping out at 20%-25%. I did have one hand selected stepping of a mobile AMD XP chip hit 40% OC.... Anyway, the 50% OC chip is the only CPU I've ever had just die. All less aggressive OCs are still in service.
I'm pointing out a couple of things by saying this.
1) Earlier in this post someone said OCing won't hurt the chip. That's simply to bold a statement.
2) Counting on a 50% overclock is risky business. Counting on it remaining stable can cause hair loss.
3) If only a modest overclock is considered "safe" the AMD chips become more attractive.
4) Given evidence that Intel chips tend to be more pricey than AMD, It's likely that a quad core upgrade in 6-8 months will be more attractive on an AM2 system.
** Tom's and other review sites consistently avoid reviewing AMD support products. ie, motherboards! I wanna see some darn AMD reviews. I know Intel is faster... and more expensive. I wanna know more about the AMD systems. Everyone just says.. "They are slower". I want some AMD reviews!!!!!!
As for the 4100+ guess I was confused. Somehow 2100Mhz + 4000+ melded into 4100+, sorry for that. Brisbane 65nm core @ 2100Mhz 65Watt. To hit the 3.0Gig mark you need just under a 50% OC. This CPU is down in price ATM... $65 bucks.
