Ok, the really easy approach to this is . . . . don't make things more complicated than they need to be, you can have everything the way you want it but you gotta be patient and take things a bit slower . . .
What your doing at the moment is overclocking too many things at the same time and eventually that's gonna do your brains in!
What I suggest you do is put some time aside for memory testing, and only memory testing, try to remove as many complications as possible so you are able to focus on the memory and memory related setting so that when something goes wrong it's easy to put right!
You need to find out how your memory works, what voltages it needs at various speeds/timings and once youve done that you can take that info and work it into the overall overclock . . . .at the moment your getting in a lather because your doing too much at once!
Im using 5:4 divider at the moment - adjusting the FSB forces me to adjust the ratio so that it keeps the RAM under 980MHz
You may be suprised to learn but when you change memory dividers there is a lot of other stuff in the background that gets adjusted also. The [5:4] memory divider is fine tuned to perform the follow function:
- It assumes you are running at 266MHz-FSB (1066 System Bus)
- It assumes you are using DDR2-666
Obviously you are not running a FSB of 266MHz and your certainly not using DDR2-666 are you? . . . but your computer thinks you are and sets a few internal chipset timings quite tight, they are tight because they are making up for the low speed. If the computer knows you are gonna be running faster FSB frequencies it will loosen some of these timings . . . you don't wanna be doing both at the same time i.e low FSB defaults with a very high FSB because your gonna go bOnkers trying to work out the problems heh!
If you don't mind putting some time aside for memory testing I can help you. It would be handy if you can reset your overclock and start again, this time around hold your horses when you reach 266MHz-FSB because that's the speed you need to get your sticks running at DDR2-1066 using the [1:2] memory divider. Once you have tested the memory at 533MHz and it is running error free with the correct voltage you won't have to worry about the memory being a problem in the grand-scheme of your overclock!
Look at this diagram a few times and see if the penny drops, all the dividers are back to front in the picture to as they would appear in CPU-z but they are right, its cpu-z thats the wrong way round!
Just to keep things really simple for the moment you can see the three pink areas are all for DDR2-1066
266MHz FSB x 2 / 1 = 533MHz RAM
333MHz FSB x 8 / 5 = 533MHz RAM
400MHz FSB x 4 / 3 = 533MHz RAM
For testing I've suggested you use the 266MHz-FSB as it's well tuned, you only have to stay at that FSB speed *until* you are really comfy with your memory and understand what volts it needs. You could possible bump up from 266Mhz-FSB to 333MHz-FSB and use the [8:5] memory divider.
I'll stick with you until your happy that your ram is running sweetly and if I have anything to do with it we will try and get then using very little volts!
Once that's out the way you can get back to your *overall* overclocking!
(voltages, temps that sort of thing)
