View Full Version : Vcore Voltage Low

03-07-2009, 12:28 PM
Hey guru's need your help.

My PC reboots itself randomly and sometimes won't boot. BIOS is saying Vcore voltage to low (running approx 1.13-1.20v)

I used to run this thing 10% overclocked, for about 3-4 yeras straight with no issues and this has just started to happen. Only way to get it to run and boot is to run with no overclock, but it is still unstable.

Mobo is a Asus P4P800-E Deluxe w/ 2.6ghz P4.

Any ideas as to wtf is happening and how to fix it?

Came back today to try and update BIOS. Back running at a steady 1.55x

Will do the update anyways and see what happens.

make sure the power supply connectors are tight in the socket, and the battery is fresh too

also as a fyi, watch out for the usb on those boards failing out of the blue one day...

its a known issue with these boards, and Ive got 2 of em

Thanks rico!

I don't use my home computer too much anymore, haven't been on it for ever to even update the bios or anything.
