Cpu @ 3.8, NB at 2.8, ram at 1500mhz 7-7-7-21. Is the ram enough?

[bmadd]

Alright been having a play and got my phenom II 720 to 3.8 easy enough with a 2.8ghz northbridge clock speed on an asus crosshair formula IV.

Running 2x2 OCZ 1333 cas7 Plat @1500 7-7-7-21-28-1T.

My question is.

Is the ram providing enough bandwidth/access speed for the cpu?

Yes... RAM speeds and bandwidth really don't bottleneck the system, just the size if it's too small.

i figured as much but with the nb speed near 3ghz i wasnt sure if it might become in issue soon.

Going up from 1500mhz to say 1700mhz i wouldn't gain a whole lot would i?

 

[Lmeow]

Apart from benchmarks, probably not. Even then in benchmarks the differences would be quite small.

Hi everyone, i had a question about this issue too, if your cpu (phenom II x2 550) has a max memory controller speed of 1333 mhz, what good is ddr3 ram 1600 speed gonna do, would the memory controller just throw the extra speed (267mhz) overboard?

Dave, Thank for the answer... i thought i post my question here, seemed related.....

Yes, generally it's just that. Sometimes certain motherboards do have a setting that automatically overclocks the ram to reach it's correct, check your motherboard manual for that.

Lastly, if you overclock, then RAM gets overclocked as well, so if you're overclocking, that underclocked RAM might get in handy.
