View Full Version : Hmm.. thought i knew but i didnt
I am not sure how the things work but running at 200mhz FSB is synchronis to PCPC3200 or 400mhz DDR right? well lets say i overclock to 250mhz FSB on the processor.. ok so not synchronis to the FSB of the processor now what do i do? I like running stock settings right now really simply because this is the only system i have. but will overclock it later on when the warranties run out and there is better stuff out and possibly have built another system. but that is beyond the point, At 200mhz and DDR 400 i would need to have a 1:1 ratio correct? then overclocking the processors FSB to 250 would what would need to be done for the memory? Also i think DDR500 would by 1:1 ratio to a processor at 250mhz FSB and would be synchronis. Also what would need to be done to run the DDR500 to match a stock speed of 200Mhz FSB? im not really sure what route is best to go right now im trying to decide which is best route to go, PC3200 or PC4000.. I was asking what manufacturer to go with earlier, but i believe im jumping ahead of myself by doing that and need to find out how the memory is going to work in my system at stock speeds and what i need to do to accomodate to make them run at peak preformance primarly at stock settings.
Well thanks for any and all help guys havent steered me wrong yet but i often time get confused and searching does give a round about idea of what needs to be done but certain situations are different and often times hard to find a perfect match

certain memory types, such as PC4000, would allow you to run 1:1 at 250 FSB, or even higher with certain modules and voltage mods.
Make sense ?
yep, but that didnt really answer any of my questions
Its kinda hard to just ask one alone they all pile up into one big question that is almost impossible to have someone else to answer for me. Sorry about all the compiled thoughts, take what you can from it if no one knows what the hell im talking about im sure i will find it out eventually. But thanks for any effort guys
Kinda trying to focus on the difference's between memory and FSB, which type of memory would be best to get Vs stock FSB and OC'ed FSB, And what needs to be done to accomodate when these differences are all mixed and matched... Final answer which is best to get PC3200 or PC4000 and whichever is chose what needs to be done when FSB is OCed and not OCed

what are your specs ? If you're waiting for warranty to run out ?....then don't overclock :-)

You just need to change your mem divider to 5/4, that would run your processor at 250 FSB and your memory at 200 FSB. Voila!

no, read his post, he doesnt' want to overclock. he wants to stay at stock with the best set up....at least that's what I think

with pc4000 and a 3.2, if and when u want to overclock just run the memory and fsb at 1-1 ratio. with pc 4000 and a 3.2 the cpu will give out b4 the memory. if u had some windbond pc3200, and wanted to overclock with your cpu it would probably also run 1-1 up to your cpu's limit . guys use the 5/4 divder when the memory cant stay up with the fsb. that occurs with the 2.4's and 2.6's and some 2.8's.so to make up for the disparity in the fsb /they run pc3200 at 5/4 ratio with very tight timings. this produces very hi bandwidth. with the 3.0's and 3.2's the good pc3200 will stay right up with the cpu also, so u can run it 1-1 with tight timings. the primary use for pc4000/4400 is for running at least 250 fsb and memory at 1-1 ratio. this memory is run at very loose timings so to get hi bandwidth u have to have a cpu capable of running at least 250 fsb. your cpu has a 16 multiplier and in my opinion is not a good candidate for pc4000. it will usually run to 3.6-3.8 which is appox 230-240. as u probably have deduced, that is not even near the memory's rated speed. if i were u i would try to find some good windbond chipped (bh5/6) modules and run your fsb and memory at 1-1 with real tight timings on the memory. this will give u alot more bandwidth than running pc4000 at 200 1-1 with loose timings.. then later on when u overclock. the memory most likey will be able to run right with your cpu to its limits(probably 225-240).
