Custom ram dividers?

[ObscureParadox]

Is it possible to edit a bios to allow a CPU to run at lower ram dividers than those already available in the BIOS or are the limitations in place due to what the IMC is capable of?

 

Just wondering as I am wanting to try something different soon if it's actually possible.

What CPU/platform are you actually talking about?

I've added dividers before. It depends on the board, the bios, and how much room it has to work in. You can't on every bios. It's more complex than that, but you get the idea.

Yeah was looking specifically at AM3 and adding some of the DDR2 type dividers in.

little bump on the subject

I was thinking about this recently, when ocing 478 (i875P). Is this limited by chipset (PLLs or dividers/(basic logic counters/registers in chipset)) or it depends on clock generator?

 

It will be interesting for example to run old Asus CUSL2 on FSB 210 MHz, RAM 170 MHz, PCI 33 MHz, AGP 66 MHz using not dividers, but separate clock generators... or are those dividers and multipliers "hidden" inside chipset (which is memory controller on this platform).

 

Interesting.
