V Core voltage problems - Page 2

post #11 of 17
Several of the Asus boards have serious issues with vcore droops under load. The magnitude of the droop is often around 0.1 volts. Although it is a well documented and debated problem, I experienced the same thing on my Asus mobo but did not have any issues with overclocking as a result. I would suggest that you keep an eye on the vcore fluctuations but not give them too much of a thought unless you're getting unstable performance out of your system.

ok i did what you said, and continued to overclock...but now speedfan says my vcore is 1.6. i have it set lower than 1.5, and it is still getting that high. the more i turn up the cpu frequency the worse it gets. is it still safe to keep overclocking, and maybe even turn up the vcore more if i have to? my temps are very safe because of the big typhoon, but that v core is beggining to worry me

What tool(s) are you using to measure the vcore? If you're seeing something significantly higher than is set in your BIOS, it's quite possible software is misreading the voltage. I would suggest using multiple programs, and if possible, finding out the contact points on the motherboard to use a multimeter on.

i use cpu-z, and speed fan...i need to update my BIOS once i get my floppy drive back...think what would help?

BTW is speed fan accurate for temperatures? And if not what program should i use to monitor system temps?

There was a previous thread like this about fluctuating voltage as i remember it was about the psu being overloaded. from how i see it ur using a 7800gt and those bad boys are power hungry. i have the same issue as u with my x connect from 1.41 to 1.39 but i ran super pi and prime 95 several times it seems to work fine. if ur having issue with stability due to ur vcore voltage then i recommend replacing ur psu. if not its should be fine

In his case, I think it's just the typical Asus droop issue. If it is, unfortunatley, a new PSU won't help.

For measuring voltages and temps, I suggest using three different programs. Speedfan and Everest typically work pretty well, and with Asus boards, you can use the program that comes with the mobo (Asus Probe, I believe). If all of the programs read similarly, you can pick your favorite and go with that one.

A BIOS update can sometimes help with sensors. It's not a guarantee, though.

i tried the programs you mentioned, and they all read pretty close... i found a spot where my v core doesnt go above 1.50 and doesnt drop below 1.46, and runs stable at 3.52 GHZ. You guys think this will be fine? I didnt update my BIOS yet but i will ASAP, hopefully that will help a little
