Low +3.3v rail voltage (1.51v)

Shdwdip · Jul 6, 2016

I am using the stock PSU from the emachines el1358g-51w. I have used a OCCT test and from what im ready my +3.3v rail is running at 1.51v. i have not noticed anything wrong with my computer until today, it reset itself just like i would. Had no problems booting up and has been running for about 8 hours since it came back on. If needed all i was doing when it reset itself i was watching videos on facebook and noticed it started to load a little slower after a few (5-10) videos.

Correct me if i am wrong in any of the terms ive said i dont know alot about computers, all self taught and google lol.

Forgot to mention if needed, I am running windows 8.1 Pro 64 Bit, 3GB Ram, 500GB HDD, and a EVGA GeForce 610 1GB. I have no extra fans no aftermarket CD drive.

Well if you got the voltage readings from the right place that voltage is way out of spec. I would suggest looking into a different power supply.

if it works, don't worry about it

Are you kidding me!?! That far out of spec could destroy the system.

Or it's reading wrong. if it's reading right, it's low, so it just wouldn't work, hence why I think it reading wrong.

okay do either of you have any suggestions on how i could get a correct reading of the voltage? still running fine as of now

13thmonkey · Jul 6, 2016

unless you have voltage measuring spots on the board, then no, software often measures it wrong.

Shdwdip · Jul 6, 2016

i honestly have no idea what im reading when i look at these programs besides temps and speed. is there any other way to contact either of you

13thmonkey · Jul 6, 2016

No there isn't. For voltages all that you need to really look for is a minor drop in voltage at high loads when you have issues at high loads, if you have no issues then there are no problems.

If there are no problems then don't worry about it, use it for diagnostics when there is a problem.

when im running any videos, programs or games the voltage never goes up or down by much i never goes under 1.51v and never goes above 1.53v.
do you think the automatic restart was just a fluke?

Can you check the voltages in your bios or with software designed for your motherboard?

OCCT can have issues reading the correct voltages. so the above two options are the best, bios or motherboard software

also if you cant do those two try a different program like HWMonitor.

if it has happened once, then i'd say bad luck, if it happens again then i'd get suspicious.

Shdwdip · Jul 7, 2016

Well like i said im self taught on this and dont know how to enter BIOS every other voltage is reading exactly what it should and never makes changes more than 0.02 up or down. temperatures are running good. No problems since the first restart.

HWMonitor is reading the same values for everything OCCT does.
