Need Help (Again)

[HomZ]

After giving up trying to get my last setup stable i replaced the board and memory with some newer kit

Ive bought a Asus p5kc and Corsair Dominator 8500 (1066 memory)

Now given the board says it supports 1066 memory and fsb i thought with my chip being 1066 everything would run nicely together, not the case

When i booted the machine and went into the bios it has set my memory to 800mhz by default, if i set it to 1066 it doesnt post after i save and exit the bios, i have set the memory voltage and timmings correctly but still it doesnt post after a reboot or exiting the bios, on a few occasions i set the mem voltage to 2.2 and it would post at 1064 ? but wouldnt let me do an install.

Currently running at 1066fsb and the memory at 800mhz its working fine although why cant i get 1066 out of it? thats the whole reason i bought it

Not intrested in overclocking just yet, although when i do get it stable i was planning on running the chip at the 3gig mark

Thanks

I wasnt sure if the fsb and mem did have to run in sync, i assumed a 1066 chip would run with 1066 memory

When i first turned the system on everything in the bios was set to auto, inc the memory, it was only when the machine was posting i saw it say 800mhz dual channel mode

According to cpuz im running a 1:1 divider although i cant see where it actually gives me the numbers in the bios, if i set my cpu fsb to 266 then the ram is at 533 (which is right) 1:1 right ?

I just assumed it would run all together at 1066, this whole new gen of ddr2 and core 2 duos has gone right over my head so im still trying to understand it all properly,

Ive been reading a few guides and im starting to get my head around it, ive set my cpu fsb to 350 with a multi of 9 so thats 3.2ghz ish which it seems to be happy with, in cpuz it now says my resulting fsb is 1400, where do we get this figure from ?

And if 1066 chips require 533 memory and 1333 chips require 667 (to run at stock) why do we have 1066mhz memory, i understand that overclocking will play a big part in some peoples choices, taking my setup for example has 1066 mem been a bad choice ? im never going to get anywhere near that am i without having a crazy fsb overclock

Sorry if i havent quite worded any of this right or if i have come across as a total noob

Could someone give me an example of how 1066 mem would run at 1066 ? will help me understand it more i think

Ill take a look over in those sections you told me about

Thanks

Hi yah Dave, ive set the memory to 2.1v which it says to do on the sticks themselves,

The 1400 make's sence now, i think ive been confusing myself with the numbers

As mentioned earlier i was running a 1:1 divider so that was never going to boot i realise that now, im currently running 360fsb with a multi of 9 which gives me just over 3.2 which im going to leave running orphos, its been running over 2 hrs now without a problem, thats running a 1:1 divider still which seems to be faster when using 3dmark, when i had the divider at 2:3 i think it was ? i got close to 1066 so i understand how it works now but ill leave it at 1:1, it seems my chip will do 3.2 easy enough.

Would setting my fsb to 400 (which would run my mem at 800 (1:1) ) and using a multi of 6 to get me 2.4 work ? would this board run at 400, would i seriously have to start bumpin the voltages to achieve this ?

If that worked i could then keep uppin the multi to increase the clock speed of the chip right ? do i sound like im understanding it

Thanks for your help guys, very refreshing to find people that dont wana take the mick

More than happy with just a cpu overclock, A memory overclock wont be happening as the memory is rated to run at 1066 and as im sticking with the 1:1 divider i wont get anywhere near that.

Im not new to overclocking ive done it with the older athlon chips and 64 bit athlons just never delved into the intel chips and with the fsb's being so much higher now and the voltage being a lot lower its like im starting at ground zero again which i dont suppose is a bad thing.

Ive read theres a lot of people running 400x8 = 3200 (1:1 Memory at 800mhz) stable with similar spec to mine so as you said working my way up i have got to this speed and are running orphos as we speak on it, this has been going for an hr and half with no errors, the only thing that is concerning me is the temps, with 2 instances running im hitting 67 degrees with stock cooler, my room is stupidly warm though, may have to order new cooler in the morning so look out for a new thread (just kidding)

I can honestly say i wouldnt push it over 3.2 so if its still running ok by say 9am ill leave it as it is

Thanks again
