Difference between similar RAM

[Leonstryfe]

Hey guys I'm trying to find a good RAM for my new system, whats the difference between the Corsair TWIN2X2048-6400 and the TWIN2X2048-6400C4

The only difference I see with the C4 is that it has an EPP. ?

I believe it is also certified to run at Cas 4 timing where the other ram is rated at Cas5.

Tighter timing give you a little more performance and more overclocking headroom

Is it worth the extra 26 dollars to get the TWIN2X2048-6400C4 over the TWIN2X2048-6400??

Are you from the US?
Do you have any other choice besides Corsair?
Do you plan to OC? If so how far with what CPU/motherboard, full specs?

nForce 680i SLI ATX with e6600 GPU - 8800 gts

Possibly OC the CPU to 3.0

Well to reach 3ghz, all you need is DDRII-667.
I think either kit will do because if you run it with DDRII-667, chances are you can bring down the Timming to Cl4 even Cl3.

I am not positive but I beleive these sticks are almost identical and should perform about the same with the CPU at 3ghz. But 26$ is not a lot of money to get higher binned parts.

So you won't likely get a lot more performance for your 26$ but probably more potential which might come in handy at some point.

Anyway is there any other memory available?

I would suggest Curcial Ballistix 667C3 I think it would be better suited for you needs.

I am very disappointed after seeing what the anniversary modules did and how those ones are performing...

@theOP
800CL4 wil be good for 500Mhz CL5 while 800CL5 will only reach ~410Mhz.
