What you mean by undervolt RAM?
There are RAMs that need lower volts (low voltage RAM).
Anyway to run the memory @higher clocks you need more volts.
I was looking on the intel site for the suggested RAM voltages and couldn't find it. This was the closest info I could find:
|There are great links to guides to overclock any of the common processors. Make sure your read these over very carefully. Join a forum on your processor, ask alot of questions to the folks there.|
In older overclocking guides, there was a lot of information about "CPU:RAM ratios", but in the Sandy Bridge guides, it seems that the CPU is overclocked generally independent of RAM.
Are CPU:RAM ratios no longer important on Sandy Bridge systems? Since the FSB on Sandy Bridge processors is locked, I'd assume you'd have to OC both components through their respective multipliers. So what are important specs to look for in RAM for a Sandy Bridge system, then? Obviously the voltage limitations, but anything else?
I've heard that it's important to get RAM that has a frequency that can be achieved evenly through the FSB, and since SB's FSB is locked at 100, frequencies that can be evenly divided by 100. Is there any truth to that?
