Whats more important?? MEM speed or CPU Clock speed??

Recommended Posts

Guest EFiNi7

The reason i ask is that ive hit a bit of a dilemna with my OC.

 

Im using OCZ EL BH5 2x512MB modules that i have confirmed can run at 2-2-2-7 @ 255MHz

and...

My San diego 3700+ looks like hits a wall at 2.9GHz @1.68 volt

 

I need to decide whether to go for the 2.9GHz CPU clock and run memory at 241MHz

or...

run my ram at 255MHz and run CPU clock lower at around 2.7GHz

 

Whats more important? Memory or CPU clock speed as far as performance goes??

The at this moment undisputed answer is CPU speed.

 

To give RAM speed first priority will only apply in very specialized applications.

 

Go for the 2.9GHz and choose a good divider, doesn't matter if it's a bit below RAM max.

Period...

As the other have said def go for the 2.9ghz

 

A64 cpus arent as memory bandwidth dependent for performance as the old sktas were

 

you can thank the on-die memory controller for that

yeah, this has been talked about for ages......

 

amen to cpu speed! :P :nod:

Memory latency would likely have more of an affect on performance then memory speed and nither competes against CPU speed for an Athlon 64/X2.

CPU speed is definitely more important because of the integrated memory controller on the A64. Due to that, you probably can't tell between a 1T or 2T or even the speed of your RAM.

 

Plus, even if you could tell, your super OC'd CPU would compensate for it anyways. You ain't losing anything. Go for CPU Speed!

Ok im running 2916MHz at the moment with 243 RAM speed at 2226-1 using 3:4 multiplier. Its primed for 8 hours without failing. Getting 28 second 1M Pi and pushing nearly 7000 everest read. I think this might be the furthest i can get, will have to try other combinations to reach this CPU speed

well i normally would agree with the others, but considering the 1.68V you have to give to your san diego for the 2.9ghz, i'd think about doing it otherwise...
