Low VCORE warning in BIOS Tags: CPUs BIOS Cooler Master Last response: November 15, 2010 12:40 PM in CPUs Share fadiii November 13, 2010 8:05:47 PM I have E7400, Asus P5N-MX and Cooler Master 500 extreme plus. Firstly, my pc failed to POST. After a lot of plugin in and out hardware (HDs, rams, etc) . It finally booted up. But then I got warning in BIOS that "Check H/W monitor. Temperature, Vcore abnormal". I looked into bios to find out that VCORE is "0.9" and it is in red. I want to know is it my motherboard or PSU dieing? Or maybe processor? Please help.

If not, if your bios can tell you what the voltage reading on the 12V rail is post that here, if the voltage drops too low then the VRMs near the CPU have to work harder to get their job done. m 0 l fadiii November 13, 2010 9:49:20 PM I checked 12v reading it was in normal range (12.1v). I loaded default settings in BIOS. Vcore reading became normal (1.2) But now it "reboots" after few seconds when still in BIOS. m 0 l Related resources Question of vCore and Sporadic BIOS warning. - Forum Low bios battery warning but voltage is ok - Forum VCORE WARNING (MSI COMMAND CENTER) Help! - Forum VCORE Warning when i5-2500K overclocked to 5GHz - Forum Low Memory Warning Windows - Forum Can't find your answer ?

If it reboots maybe your V-Core is too low? try bumping 1x and save Bios and reboot and see if it happens m 0 l fadiii November 13, 2010 10:44:48 PM Unfortunately, it is not a high end board so it does not have any option of changing VCORE. And there are not any bios updates. And VCORE right now is back to normal. But it keeps rebooting even when in BIOS.. m 0 l ahumphers91 November 13, 2010 10:46:08 PM Hmm, what is your Bios options then? Anything about cpu voltage? m 0 l fadiii November 14, 2010 7:08:28 AM Nah, nothing about the cpu voltage. m 0 l 55Range a b à CPUs November 14, 2010 1:33:26 PM Hmm, so you don't have the option of v core nor cpu voltage, which is the same - Nor bios upgrade what do you have on the bios ? m 0 l ahumphers91 November 14, 2010 1:39:57 PM Seem's like your SOL then? I'm not sure on that one bud. m 0 l fadiii November 14, 2010 4:20:46 PM Could it be PSU? m 0 l ahumphers91 November 14, 2010 11:33:18 PM Buy a tester or try another PSU and see if you have the same problem. I can't really say for sure, but that would be your best bet. m 0 l 55Range a b à CPUs November 15, 2010 2:57:15 AM try with another psu- m 0 l mosox a b à CPUs November 15, 2010 3:28:20 AM Do you have some power saving options enabled in your BIOS like EIST, C1E? m 0 l fadiii November 15, 2010 7:50:05 AM Now, it does not even boots!.. and I tried another working PSU..no luck! m 0 l mosox a b à CPUs November 15, 2010 8:08:25 AM Remove the CMOS battery on the mobo and put it back to clear the CMOS. m 0 l fadiii November 15, 2010 9:26:32 AM ^Did that. Nothing happened. m 0 l ahumphers91 November 15, 2010 12:40:18 PM Probably the board is crapping out. Sorry man, maybe try another board with the same socket to test your cpu, but i'm thinking it's your board. m 0 l Can't find your answer ? Ask !
