Would there be any point in having a divider for my RAM here?

My kingston hyper-x ram blows chunks (can't go above 205 fsb at 8-3-3-2.5 stable) and I have been forced to settle my overclock for my 2400+M to 2.55 ghrz (204x12.5) becuase of it. My question is, would there be any increase in performance were I to have a higher fsb with a divider so my ram can stay at close to stock speeds? My NF7-S can get up to 240 fsb (RAM NOT stable no matter how many volts) so would that be better than 200 fsb?

If I am not making any sense, just tell me.

You heard right. mwmorph is misinformed or confused. NEVER use a memory divider with an Athlon XP unless you have some crappy RAM that can't get to 200 MHz (400 DDR).

The Athlon-64 is a different story... you can use memory dividers with that and not see any performance penalty.

*EDIT* Unless of course you feel you can get a couple hundred more MHz out of that processor, which is doubtful unless you using water or phase change cooling.

Ugh, yeah. I quit. I can't get a divider that will help me out here. The closest I can get to 400 mhrz is 360 (my fsb is at 230, I can't go higher) and performance is worse.

Just out of curiosity, what's wrong with the AXP dividers?

axp takes a big performance hit from running ram async. they fixed this on amd64s and pentiums work dividers pine too.

There's nothing to really "fix." It's just the way it works because of latency and whatnot. By running the RAM and FSB out of sync, you're creating more latency. It's not as big a problem with the P4 and A64 because the memory controller of both of those works at a much faster frequency than the Athlon XP. So one or two clock cycles is a much smaller period of time for those than it is for an Athlon XP.
