Just taken delivery of some Twinmoss pc3200(2 x 256mb) to replace the pc2100(2 x 256mb) Thinking ahead for cpu change in near future ,Thing is getting same memory bandwidth score in sandra 2k3 or less (2001/1973) is this becuase of the fsb of my current cpu being 133mhz ?


Current setup
Tbird 1.33 @ 1.4
2 x 256mb pc3200(Twinmoss)
Chaintech 7NJL1 Epogee
Creative Ti4200 64mb

T.I.A

Mythed and a little confused

Short response, yes. :D

On my system (see the sig below), my memory bandwidth in Sandra scaled linearly with FSB speed (i.e. FSB 133->166 = 25% bandwidth boost).

You can pick up an XP2100 (mine runs well at 166 FSB) for about $90 on NewEgg...

Cheers,
JND

Did you have to manually unlock it or did your board automatically unlock it? If the board does it for you I can save me some dough now.

all nForce2's automaticly unlock the TB cpu's. You dont need to change the voltage or multipliyer to run the 2100+'s at 166FSB though. Just decent cooling.

And Bartons? Wonder if my nForce2 Shuttle unlocks the multiplier in my 3000+. I'll have to try this tomorrow.

But what speed is your new memory running at??
Is it @400MHz or still @266 MHz?
Having a 266 FSB, higher memory clocks don't give you much increase in performance, but you still get some. DDR333 gives your better scores that DDR266 with 266FSB. The 25% more memory bandwidth may give you 5-10% increase, maybe. But DDR400 vs DDR333 with a 266FSB is not significant, almost 0-1%. So, DDR400 vs DDR266 should still give you a 5-10% increase.
I guess the RAM is still @133MHz (x2 = 266). Memory benchmarks like Sandra's should clearly show the greater memory bandwidth, unlike other entire-system benchmarks.

i was thinking about getting ddr400 But are u saying the performance boost from ddr300 wouldnt ba that great. Or were u saying that having a fsb of 266 would give me crappy ddr400 performance. Does ddr400 run at a 333mhz fsb?

I myself picked up 512MB TwinMOS PC2700 running @ 266MHz but only cost 54 form a local shop :)
