I am currently running a p3 1.0 with 512mb pc133, so its time to upgrade...ive looked into almost everything possible. i have never oc'd a cpu b4 aside from the fact that my friend oc'd my pentium 200 to 233 with a simple jumper switch lol. anyways, i have looked into amd 64's intels p4 northwoods/prescotts/478/lga options. i am considering overclocking my new computer. i have been doing a lot of reading on this forum and gaining a load of information. i would like to stick with intel if at all possible although i know some ppl believe amd is oc king. i am concerned about heat issues and instability. i am not looking into putting a lot of money into this comp but here is what i have come up with. I want around a 3.2 whether it be a prescott or northwood. i have heard some things that concern me about the "preshotts". i dont now want to have to purchase water cooling or some expensive form of cooling but am willing to put a little money into a better heatsink/fan if i do oc. i was looking into the asus/msi/soltek boards but dont really know the best...i know that intel has a nice board but all i hear is that with intel boards...good luck with a nice oc. i am thinking i would like the 875p chipset, i have done my research on the 925x as well and it seems that pci-express is not putting up impressive enough numbers to spend more money for that setup. i was thinking about going ocz for ram too bc i have seen some nice benchmarks and heard some good things about them. now the one thing that i would like to be cleared up on is the ratios. i have read about the 1:1 and the 5:4. meaning fsb to ram ratio. now i understand that both cpus i listed run at 200mhz (200x4). now one thing that i do not really understand is what are the guidelines to increasing the fsb. i mean can you say hmm i would like it to be 213, or does it have increments it goes by. i know that fsb x multiplier = cpu speed...i would like to take a 3.2 with a 16 multiplier and raise the fsb to 250 making it right at 4.0ghz. i know that with a 250fbs a 5:4 ratio would work with pc3200 (200mhz), but is a 5:4 always stable? is a 1:1 always stable? is there just a place in the bios to where you can change the fsb or the bus on ram to any value you would like? and im also a little sketchy on the voltage to cpus. any advice or explanations would be greatly appreciated. thnx in advance.
