Can You OC A64 With Value PC3200?

Looking at real-world performance in games, and not synthetic benchmarks, I feel the extra expenditure on tighter-timed RAM is not justifiable. Therefore I want to get 1GB x 2 value RAM for an AMD 64. However, I'm wondering how OCing works on this platform - if I get value PC3200, it probably won't overclock very well, and if the memory speed needs to be synchronous with whatever in the CPU needs to be OC'ed, I won't get very far.\


So how does this work? Is there a divider I could use so that RAM stays at 200 and the CPU FSB speed (well, that's P4, don't know what it is in AMD) can be increased? What kind of performance hit do you take doing that relative to running synchronous 1:1?
 
you can run dividers. check out (cf)eclipse's guide stickied in the amd forum. You may have to fiddle with it a lot more, however, without the flexability. A recent build I did used corsair value select, with 2.5-3-3-8 timings. the ram actually overclocked to 240mhz at those timings with 2.85v, but running a divider ran me into some problems. If the resulting ram speed with a divider was between 175mhz and 210mhz(right where you wanna be) at cas2.5, no post. Tried my personal tccd in there at cas2.5, same thing. HOWEVER at cas2 which my tccd is able to do till about 215, it was perfectly fine. So the point here is that having the memory controller on the cpu is a blessing and a curse, you may get one that doesnt like certain things. But its completely possible, id say go for it, if you can get cas2.5 instead of cas3, if the price dif isnt too much.
 
Yes I see some 2.5 on Newegg that is 80 bucks for 1 GB PC3200, which is a steal, really. I'm a bit miffed as to why the RAM you mentioned would do 240 @ 2.5 but not 210 @ 2.5, simply because it is on a divider in the latter case? Odd...but nonetheless I'll probably try it out.
