Example - 2.4c O/C to 250mhz runs at standard PC2700 memory speed with 3.2 divider = 3.0ghz

However a 2.8c at 250mhz whilst running stock 166 (333) for PC2700 would need to achieve 3.5ghz (Very High)
To run a 2.4c at 3.2ghz the fsb needs to be 267mhz with 3.2 divider giving 355mhz memory settings (Possible with good PC2700)

Hope this is usefull

Well that idea didn't work, clearly you cannot maintain columns in the posting with original word format.

these forums are a b**** when it comes to keeping the intended format!

ok this is closest thread i could find to answer my question... can i run a "c" series with ddr 333? without a performance drop or anything? i dont plan on over clocking and really dont want to buy expensive memory now if newer ddr2 will be out in next 6 months or so but would like to upgrade my 2.26 (533) to a 2.6 or 2.8 c series. so basically asking if performace will be hit by using my 333 memory?
thanks for any help
