Chill, your earlier post was only two hours ago. Sometimes, depending primarily on your ISP, a news posting takes time to propagate.
Your memory operates at the speed set by the FSB speed modified by the synchronous/asynchronous memory setting (if any.) The SPD contents don't control that speed. The SPD contents that DO have an effect are the parameters like CL.
You can set any FSB speed your BIOS and pll provide, it is just that you memory may not opperate successfully at the requested speed. YOU choose the speed for the memory (unless the FSB is set automatically by the CPU.) The speed at which your memory operates (or tries to) has nothing to don with the memory rating. If you are luck, have cool temperatures, have high quality memory (NOT the same as higher PC speed), and perhaps raise the memory supply voltage a bit, you may get some PC2100 modules to operate faster than PC2700 modules - it's called overclocking.

How dare you guys hijack a thread or post anything off topic in this newsgroup!!! ;^)

LOL. Me, personally, I would never post a message that didn't contribute.

Here's another:

In alt.comp.periphs.mainboard.abit, Phil Weldon ordered an army of hamsters to type:
Yeah I see it now
I'm so impatient
Thanks Phil.
I assume that its possible to get some PC2700 sticks to run faster than 3200 etc?
Question, are PC4000 sticks worth it? Is there going to be a change in ram type soon or are current DDR modules only going to get faster over the next few years making faster modules a better investment. Of course with the faster modules I assume its better for an overclocked system. How much is RAM a hinderance on overclocking. Is it really possible to take a cpu so much higher with more expensive ram? or is there only a little gain?

The short answer is "It depends."
A longer answer includes a bunch of stuff.
#1. Beware of memory sold as PC4000 or PC3500 or similar descriptions. While the lower classifications are official standards, there really is no standard for classifing memory as PC4000 or PC3500. Memory so classified will very likely work reliably at the advertised speed, but it will not have nearly the number of compatibility checks that memory meeting official standards has.
#2. The higher the speed classification of memory, the less likely it is to overclock a large percentage. No module assembler has a monopoly on "special" memory chips. There are only a half dozen or so memory chip manufacturers (which makes sense - memory chip FAB's cost over $1,000,000,000 each - and all the smaller "manufacturers" of memory pay someone like Samsung, Hynix, or Micron to do the work.) The only way to get PC4000 performance level is to be highly selective in picking the best of a batch of chips that are designed and manufactured for, say, PC3200.
#3. Since Intel CPU's are multiplier locked, the only way to overclock is to raise the FrontSide Bus speed. You can use the memory asyschronously (at less than the FSB speed), but there is a performance penalty. Historically Intel CPU's have been very good overclockers since the demise of the Pentium 60/66 which could barely live through normal operation. With a well chosen motherboard, good (but not necessarily exotic cooling, and fast memory Overclocks to 30% to 60% are more the rule than the exception. AMD users have the choice of raising the multiplier in addition to raising the memory speed.
#4. As to the question about what the future will bring; There three or four motivations for overclocking computer systems:
a. the joy of experimentation and custom modification b. getting more performance for less money that with stock systems c. bragging rights for the the fastest system d. you have convinced yourself that every possible Megahertz is necessary for your favorite games. According to where in this field you fall you may be willing to buy new components every time a new, faster component comes on the market; or you may buy at the "best bang for the buck" point. Or you may delight in squeezing amazing performance from the cheapest possible components. I guess it all comes down to what you enjoy doing and how much you are willing to spend. These considerations are more important than what is going to be released next because no one can really predict the future and knowing the future would not be of much help if you don't feel the necessity to spend $500 for the next and fastest display adaptor or $700 for the next and fastest CPU.
If I must go out on a limb for this question, I'd say the recent change to dual channel DDRRAM and an 800 MHz FSB has a lot of room to run for Intel CPU users - any high speed DDRRAM will be good to go long after your CPU and motherboard are past their prime. Just my opinion, I could be wrong.

b1. Getting more performance than you can buy at the time; Eg. My AMD XP 'Barton' 2500+ running happily at 12x200 for 2.4GHz - the fastest AMD CPU available when I started running it at that speed was the 3000+, 13x167for
2.17GHz - even now, 4 months later, the fastest AMD XP CPU available is the 3200+ running at 11x200 for 2.2GHz...
Same for Intel - plenty folks running P4s at 3.6GHz & higher with 'heroic' sub-zero cooling. Eg. Vapochill & Prometia...
