BIOS Voltages

post #1 of 12
Thread Starter 
I have essentially reached a limit for my CPU speed due to temperature, however I am curious if my current settings could be stabilized better with increases in the northbridge and frontside bus termination voltages. I tried looking up what either will allow, but I was hoping someone with direct experience here could enlighten me as to how those voltages affect overclock stability, etc., especially for my ASUS P5W DH Deluxe motherboard. Also, an explanation of what exactly the frontside bus termination voltage is would be appreciated...

The P5W is safe at the max NB and FSB termination voltage. Use a dual Prime95 stability test, if it passed 8+ hours you system is pretty stable. I am not sure exactly what FSB termination voltage is though...

Will increasing the voltages help my OC stability?

The only way to know is by running Prime 95. You can't make it any more stable than stable!

Increased voltages will increase your stability. Tehy can only affect stability in good terms. The maximums are safe with this MB, but I recommend you to lower it by one on the MCH.
Don't know exactly what is the FSB termination, but it must match some voltage. With this one you can only try the different values and see wich works best.

OK, I will try increasing the voltages. Why do you recommend lowering the MCH voltage by one setting? Temperatures?

Doesn't seem like anyone knows what the FSB termination voltage does... :/

Hey I have a p5n-e and im new to overclocking. My mobos northbridge voltage limit in bios is 1.7ish. Im planning on putting in an after market heatsink on my north bridge. Is it safe to run at the 1.7 if its needed to run a high stable over clock?

My guess would be yes, especially with an after market NB heatsink, however I would check with others and I would look up your motherboard temperature specs. I would also suggest you make sure your temperatures at the default voltage have lowered significantly with your new heatsink before you up the voltage.
