CL4 Vs. CL5

So i'm gonna go ahead and get 2Gb of Corsair PC2-6400 RAM and there seems to be around a £25 difference between the CL4 and CL5 stuff.

How much actual difference in performance is there between the two?
 
Heh heh heh....by real world I mean that harshly tinted reality with games and video encoding :p

Not fully retired, just a fairly thorough hiatus :B;)

What about benchies, superpi and cpu benchies, 3d etc...

Not really my sort of thing, i'm mostly interested in 'normal' stuff like gaming, applications etc...
 
I understadn that but for the benfit of others that may read this thred it could be of use to them.

Kenny, plese can your detail where CL4 benefits most over CL5.

Cheers

SuperPi 32M mainly, the difference might begin to show up in 3DMark01 if you're really squeezing for points. Tighter CAS helps a little in PCM05.

CAS 4 Vs 5 and the MHz difference that comes with it... for most benches you can write any effects off as test discrepency, the differences are probably that small.

(especially true for C2D chips)

Been thinking about doing a chart with different timings and MHz to show this, but my GPU is holding me back.
 
Do it based on CPU intensive apps mate.

Also I was thinking about all this - aint it a shame that the CPU cores can't assign themselves to different memory banks.

Would make vista more attractive if we knew we could shove 4GB (4x1GB sticks) in a system and see that both cores were using the ram independantly (core 0 uses banks 1&3 and core 2 uses banks 2&4 for dual channel boost too).

I realise that becomes more complicated with more cores but I guess you could still split 4GB (cores 0&2 uses banks 1&3 and cores 1&3 uses banks 2&4) - or maybe 4 cores could use a bank each and have mahoosive performance boosts (4x2GB anyone?).
 
I've seen some 4x 2GB kits, and they're not actually that badly priced! Although, I would imagine the memory controller would have a right work out!!
