I am pretty new to Overclocking. I have never done it except for once or twice for very short periods of time, and very small increases. I am looking into getting a 1.8A P4 chip in the very near future.

My Planned to be upgraded Specs are..

Sparkle 350W PS
P4 1.8A
Abit TH7II (not sure about raid yet)
512MB PC800 Samsung 16 chip
ATI Radeon 8500


Pieces from my current system I have to keep for the time being...

SB Live Value (OEM)
20GB IBM HD (think 45GXP?)
NIC


I can't help but want to overclock this P4 and RDRAM because of the stories I have heard on this board. I know the P4 and the RDRAM can take it, but I worry about the affect on the PCI bus. I know this Motherboard will allow me to set ratio's to overcome some of this, but from reading many of the posts about this issue, it seems in order to clock the PCI bus in spec, I have to run the FSB at 133... which is a little higher than I wanted to overclock (call me a chicken). Is this true?

For example, is there a way to maybe push the 1.8 to just 2Ghz on a 111x4 FSB without increasing the PCI bus? Could someone please explain this.. I know on a 100FSB default the pci is 1/3 or 33 and the AGP is 2/3 or 66.

I was considering the 1.6A, but if it won't quite do 133x16, won't I be pushing the PCI bus way too much? I was thinking that if the 1.6 would not go to a 133FSB that at least if I bought the 1.8 I would be happier at default...



Also.. do the people pushing their chips to 600Mhz or so overclocks worry about reducing the life of the chip, or is this just something paranoid people make up?

On the RDRAM... does running the Samsung 16 module ram at PC1066 greatly increase the heat it puts off to the point where more case cooling or a fan over the ram would be needed?

Thanks in advance for the responses...
