3:4 ratio. Huh?

post #1 of 16
Thread Starter 
cpu-z show my fsb:dram to be 3:4.

is that normal? i'm not even overclocked

i took some screenshot of almost everything on cpu-z, so you can help me more


thank you

Yes, this is very normal on Intel platforms. Your D940 has a quad pumped fsb of 800MHz (200x4), and the memory is DDR2 533 (266x2), so the ram divisor acts like this: 200/3*4=266, so you have 800 fsb paired with 533MHz DDR.
If you had for ex DDR2 667 installed you could have used a 3:5 divider and have 200/3*5=333 (aka DDR 667)

I'm not sure what you mean by it's underclocking him.
There's actually little to no benefit at all in running your memory at a higher frequency than your CPU since the CPU is the one doing all the computations and it's merely being fed data by RAM.
Moreover, when you're running a 3:4 FSB:RAM divider it will most likely prevent you from overclocking your CPU very far. As you raise the FSB your memory will quickly max out (since it's already running at 266 MHz).
The best thing to do is to set the memory at 400 MHz (FSB:RAM at 1:1) then start overclocking from there.

Depends on your temps...could just need a little more voltage....

my temp is 38c idle

and 3dmark05 crash during the first cpu test

edit: it's fine now, i uped the vcore and 3dmark05 did not crash. i'm still stuck at 4ghz though

------------------------------
Go back into your bios setup and change your 533mhz freq to 400mhz. Like another member stated earlier, then you may want to look at your timings and notice that you have a set of 2x512 that will run @ 3.0-3-3-8 and you have a 2x512 set of dimms that run at 3.0-3-3-9 according to CPU-Z? I would say that once you get your CPU maxed and your timings are adjusted down to there lowest settings the dimms with the higher setting will end up your max. I would consider taking one set of your 2x512 dimms out while you find your max overclock? Others may disagree on this but unless they are twin sets the slower dimms will dictate the SPD timings.

Also if your idle cpu temp is 38.c what is your full load temp? My presscott has ran 63.c @ 4.2 on stock air but I gut it of running programs etc.. to do it and at idle I run 36.c-42.c. I didn't know the 9xx series were that hot better ask a 9xx series overclocker about your temps and you voltages as you get along with your overclock,

Also run another CPU-Z and post again soon. The screenshot of cpuz (cpu page) shows you v-core @ 2.656 ooch! I hope thats WRONG the cpu would surely start smelling like worn brakes or something at the setting?

Looks like you have room to go with it? My bad on the temp at idle I thought you were in a normal restart etc.. not an overclock.

Theres no way I could ever run an idle temp of 38.c and a 4.0ghz overclock?

Good job the big 4.0!

i'm not sure why it is wrong, but it is what it says. i didn't do to anything my cpu when i took that screenshot.

i did it before overclocking, then up it one notch because the divider got to 4:3

Quote:

it got up to 54c during pcmark04

in pcmark05, it got up to 59c. the computer eventually crashed



i'll do what you suggest later. thanks


i have 2 quick questions

1. do you leave your overclock on 24/7?

2. i heard it's not good to overclock, it shorten the lifespan of the cpu, and can desynchronise the cpu. is that true?
