Setting RAM to 2:3 in BIOS gives weird results

Recommended Posts

Running BIOS 623-3 and bus @ 300Mhz. I want to run the RAM stock (not overclockable RAM) and have it set to 133 (2:3) in BIOS. However, that results in the RAM frequency to be 192.7Mhz instead of ~200Mhz. Not a big deal but it irks me... Anybody got any ideas?

It should be set to 200: 1./01 in Dram configuration in bios.Go down to 4th screen in link.

It's in one of the stickies somewhere but the formula for mem freq is

 

Mem freq = (FSB x multi) / Int(multi x (1/divider)) where Int = Integer value, rounded up

 

So for your case

 

Mem freq = (300 x 9) / Int(9 x 3 / 2)	  

	 = (300 x 9) / Int(13.5)

	 = (2700) / (14)

	 = 192.8

Thanks... Makes sense now.. Somehow misguided by the values given in BIOS... But 2700/14 makes more sense.. If I could push my CPU to 2.8Ghz I'd hit 200Mhz nominal frequency. But Core #0 won't run stable.... :/
