CPU mhz vs DDR mhz - Page 2

No.7 · 27th Apr 2006, 06:45 PM

Ah, great info. Thanks!

I found the amd calc tool and also did the settings that Papercut suggested but for some reason it didn't boot with the ram at 227 or something mhz.

It was a bit difficult to find a good combo of settings that I liked, my aim was to get the ram at around 200mhz. The second best I found was setting the ram to 287 and I rejected that.

Instead I am now running cpu at 310mhz *8.5 which sets the ram to 202 which seems to be working ok. It gives me a cpu running at 2.6ghz and that is an OK OC for me. It is not 100% stable in for example 3dmark05. It doesnt pass my 'run all night' stability test but it runs for at least and hour and also my real world application game test is doing fine (playing BF2 online for a few hours straight). It can also handle superPI so it looks good.

The bios for my mobo is known to have several issues, especially with memory handling so I am waiting for an update from asus before not accepting the 99% stability issue.

Thanks again!

Isn't raw CPU power more important than any RAM settings?

I have only built two AMD 64bit rigs so far ( a 3200+, and a 4400+X2), but I have to agree with those who say get the most out of the CPU, and just set the RAM so you run stable. I found after days of tweaking and testing that the speed of the CPU is much more important.

So about raw cpu power, should one aim to get as high HTT(fsb) as possible?

I have found, in sisoft, that now that I run 310mhz HTT that I get the same RAM bandwidth regardless if I run cas2 or cas3 with all other settings the same. But it is only a testprogram, but still pretty interesting.

I rather run at 15x200 than 10x300...

you don't need high HTT as the memory is no longer on it.
even at 700MHz you get more than enough bandwidth for the rest of your system components.

I prefer Super Pi over Sandra for testing RAM settings. Sandra just gives you a number, but your RAM settings will affect the calculation time in Super Pi...

Yea, I use superpi and Everest.
