How to make your mobo recognize 1066 RAM as 1066, not 800

Hey guys,

I'm still new to mobos and BIOS and so I'm looking for some help. I have a P5Q PRO ASUS mobo, and just got 2 sticks of OCZ 2G DDR2 1066MHz RAM. For some reason, the BIOS is reading it at 800 MHz, with no option for raising it any higher. I think this may have something to do with the voltage setting, or perhaps the timing, but not having worked at this level before, I'm not certain. Any suggestions?

Thank you in advance.

OK - so I'll check out OCZ's site and see what they have listed. From what I gather, if I then manually set the RAM settings to the manufacturer, it should run higher than the 800 MHz listed by BIOS, but what you're saying is that it won't say that?

the memory is tied to your FSB speed

the fsb speed is usually detected automatically by the mobo dependign on what cpu you have

for instance my FSB is set to 425hmz and my mem runs at a ratio of 2:1 compared to the FSB, so the mem is runnign at 850mhz


there are two ways to change the mem speeds

1) change the ratio from 2:1 to something else that gets you to 1066, this method will not OC your cpu or increase anything other than the mem clock

2) increase the FSB, this will increase CPU speed and mem speed, this is akin to overclocking

with method 1 you need to make sure the mem is gettting enough voltage (you can check specs on the manifacturer's website or thru CPU-Z)

with method 2 you need a lot more stuff, like a better cooler for your CPU, more volts to yer cpu, more volts to you mem, maybe more volts to you northbridge, etc etc

i woudlnt advise method 2 until you get more familiar with OCing and what not.
