Voltage rails how low ? / cause of complete shut down

Fuzz · 1 Jul 2008 at 23:13

How low would you expect to see the rails go in windows.

This case is now pretty much rammed with stuff and was wondering if the extra RAM has just tipped it over the edge..

PC now turning off randomly, I mean a complete shut down, no errors, no warnings, no locks ups nothing, as if someone had cut the power.

Basically I have
+12v = 11.93v
+3.3v = 3.23v
+5 v = 4.85v

Tugging at straws at the mo as the memory is underclocked as far as I can set it (900 instead of 1066 and 5.5.5.18 instead of 5.5.5.15) (450FSB)

Within Limits and is that with a Calibrated digital Multimeter?, because Software can be a mile off.

A very un trustworthy Everest, that has now just once again screwed over some of the temp sensors.
(stopped using it a while back because of all the issues I had with it, now it's just ate them again Grrrr)
Typical..

Will bring the fluke home from work...

Do you have enough voltage going through the Ram? e.g. for most of the PC8000+ kits I've seen they want 2.0v+ so you may want to check that in bios if you haven't already.

As helmutcheese says though that would be well within specifications for the PSU.

You upped your northbridge volts with the extra ram added?

RAM has 2.27v going through it (2.2v standard I think) so one notch up from normal.
Northbridge I have to guess at 1.6v ish (I'm at work at the mo and so not in front of the rig) The voltminder LED on the MB has turned yellow, I think I'm two notches into that area and it's giving off 74 ish degrees c..
Using the 3 fan combo that came with the second set of ram sticks I shoved that over the NB heat sink until I can get a water block sorted and can hold it around 70 degrees.
No idea whether that's about to fry it or not. :confiused:
