Fsb <--> Ram

[pc_boy]

if you have a CPU with 333MHZ FSB, and you have DDR400 RAM, then you wouldn't benefit from the RAM as much because your CPU only gives the RAM work at a rate of 333MHZ, and you won't notice any difference if you have your RAM at 400MHZ or at 333MHZ...

is that true??? (hope not)

unfortunately i think so

 

[PizzatheHut06]

Yes, the RAM will automatically underclock itself to run at the 333 MHz speed. I would still recommend sticking with the DDR400 RAM as upgrades will be possible in the future.

ah, dang... so should I underclock my RAM and lower the cas latencies to get more out of it?

 

[PizzatheHut06]

I wouldn't mess with the case latencies, there is no point. A 2-2-2-5 is not at all noticeable different from 3-3-3-8. The difference is nanoseconds, literally.

 

[Nitestick]

it will probably run best if you allow it to configure itself

i set the RAM speed to AUTO, and now it sayes the same as the FSB..i overclocked the CPU FSB to 177MHZ, and I set the option on the timings to be "aggressive" so the mobo automatically set it to 2337
