Noob to OC, and very confused even following guide

post #1 of 16
Thread Starter 


I've been trying to figure this out, but its not making any sense to me. Maybe my BIOS settings are called something different than explained in the guide. Some of the stuff is obvious, such as the CAS Latence, tRP, tRCD, tRAS etc. But others are not so obvious to me, such as the CPU/memory ratio.

In the picture, you should notice that CPU-z shows my core voltage at 1.35, however the guru monitoring on the top left shows the voltage at 1.5. I also found that to be very curious.

Welcome to the fourms.

Yes, different BIOSes unfortunately use different names for the same functions, and it can be confusing to find your way around your BIOS for the first time. One thing that would help us to help you would be if you filled in your system specs by clicking on User CP near the upper left corner of every page. There is likely someone here with your same motherboard that could give you specific help.

all the mem ratio is you ram frequency compaired to your cpu frequency
i use frequency as a loose term (also called htt,fsb,speed) yours should be represented by a number(probly around 200? or maybe less) your rams speed is the same giving you a 1:1 ratio.

welcome to the forums plz fill your specs and enjoy.

EDIT: a little more detail on that. my cpu runs at 2.682 right now. i remove the divider and its 298Mhz my ram is also running at about that i think there for i have a 1:1 ratio.

Make sure you have the most updated BIOS for your board as well. I know ABit did some tweaking to their temperature calibrations in a few that were released a little bit ago.

Hi and welcome to the forums What kind of an overclock are you aiming for? Are you looking for a simple one to just get a little extra juice, a good overclock that you can run 24/7, or an extreme one that probably won't last you as long?

The best basic approach.
Determine your RAMS max stable voltage.
Under clock the CPU by reducing the multiplyer, that way you are OCing the RAM when you up the HTT or CPU bus speed to determine the fastest it wil run stable. Use memtest to determine that.
The n set a high divider on your RAM to OC the CPU to determine it's highest stable speed.
Having those factors will help a lot.
Here is a great guide on the above basics I described.
