Memory slot not working

shawnhcorey · Nov 22, 2013

My computer freezes randomly when there is memory in both the slots but works when memory in only the first. It freezes at random, even during BIOS, so I'm pretty sure it's not a software problem. I tried both modules in the first slot and they both work there. I tried the other slot and it freezes.

Is this a problem with the motherboard or possibly the power supply?

Some tech info:

$ uname -a
Linux sage 3.10-2-amd64 #1 SMP Debian 3.10.5-1 (2013-08-07) x86_64 GNU/Linux

Don't think the power supply can cause memory to fail in a specific slot. If you have some compressed air try blowing the slot out, maybe you just have some dust in it, as a final measure, try reseating the processor, if its just a bit off (the memory controller is on the processor in most newer chips) it can cause a certain slot not to work.

do a memtest on both stick on memory one at the time and if the pass i would look at the motherboard slot .

shawnhcorey · Nov 22, 2013

I did one memtest, a complete pass thru but only once. There were no errors.

scout_03 · Nov 22, 2013

you have to made at least 5 test to be safe and if they alll pass then give a look at your motherboard .

I'm fairly certain it's the motherboard but the power supply has several circuits to send power to it, in part to isolate any feedback. I just don't know enough about it to rule it completely out of the picture.

use this on the sensor parts ans report what it will read http://www.hwinfo.com/download.php

that a parts in the motherboard and the cpu also the gpu that give the temp and voltage that is what we need to see if there is something abnormal in the temp or power use the software on the link .

shawnhcorey · Nov 23, 2013

You mean:

$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +27.0°C (crit = +127.0°C)

k10temp-pci-00c3
Adapter: PCI adapter
temp1: +17.5°C (high = +70.0°C)

scout_03 · Nov 23, 2013

you should have a page mark sensor status and not virtual this give the memory use the cpu core volts the mb volts the cpu clock the core use in % the cpu temp the motherboard voltage the hdd temp the pm volts and the gpu details temp speed anv voltages .

shawnhcorey · Nov 23, 2013

The is no actual temperature read. There's only this virtual hocus-pocus. The motherboard is just not equipped with one.

It sucks but that's all there is.

scout_03 · Nov 23, 2013

your on linux that why this software could not read the sensor see if you could find something on linux forum to help you read those values .

shawnhcorey · Nov 23, 2013

I doubt it; there are no values. It is not equipped to read them.

scout_03 · Nov 23, 2013

this for linux http://xmodulo.com/2013/11/monitor-system-temperature-linux.html

shawnhcorey · Nov 23, 2013

`lm-sensors` is now called `sensors`:

$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +27.0°C (crit = +127.0°C)

k10temp-pci-00c3
Adapter: PCI adapter
temp1: +18.0°C (high = +70.0°C)

scout_03 · Nov 23, 2013

those temps are good ,it could be motherboard issue since i am not familiar with linux i let the other who use it help you stay around .
