Hardware :: Memory Needs To Stay Together With The Same DIMMS That It Came In The Pack With?
Oct 20, 2010I am installing two sets of DDR 3 RAM in a supermicro motherboard with a single processor. There are 6 DIMM slots. Does each pack need to be installed in the same channel, or can I start from one side and install all six DIMMS? Basically my question is if memory needs to stay together with the same DIMMS that it came in the pack with. Again the memory is the same brand, same type, same speed, and will be populating all six slots on CPU 0. I was told this does effect the system, but have heard different answers.

Apr 8, 2011I have been battling an issue for a couple of days and I have it down to 2 possibilities. Memory or mobo. A server in the DC is being very sketchy. Sometimes it will boot fine, sometimes it will boot but will not show all the memory, and sometimes it will hang before it even posts. I have replaced just about everything inside the system except for the memory and the mobo.
I would like to test the memory before replacing either because both are a few hundred dollars. The problem is, the memory doesn't log any errors and running a memory test with ubcd doesn't work because it's ecc memory. I thought I remembered hearing that there is a way to run a memory test during a Centos or RHEL installation, but I can't figure out how.
The memory is
DDR2 667 FB-DIMM
and the board is
Tyan S5380
Fedora Hardware :: Memory Test Passes But It Breaks Before Finishing?
Jun 24, 2011I've got this really weird problem and I'm not even sure if it is a problem. I recently upgraded the RAM on my Compaq Presario Laptop from 3GB to 4GB by swapping out a 1GB DDR to a 2GB DDR so now it contains two 2GB DDRs. The BIOS shows 4096 MB of memory, Fedora shows 3955MB (Probably after the reduction for the video memory) so that's fine.
But I noticed a very quick flash during boot in between the Compaq Screen and GRUB. It only started coming after the RAM upgrade. I'm not able to make out what exactly is written. It's too fast. Will try with a proper camera at home. In any case, I could make out some large number probably in the order of gigabytes written in bytes. Again, not sure of the exact value.
So I get a little curious about this message and decide to run a memory test. It's working perfectly. Around 74%, it stops and says Memory Test Passed and moves on to check the HDD. I try the same from the BIOS. In the BIOS, it's a progress bar and no percentage value mentioned. Though the BIOS says 4096MB of memory, the progress bar also stops at roughly 75% and says passed. I'm not even sure what to search for on Google though I tried and got no similar results.
why this is happening? Since it's stopping at 75%, I have a feeling that the change in the amount of RAM hasn't been made in some place by the system.
Ubuntu :: 10.04 Kernel Panic-not Syncing And Failed Memory Test?
Aug 7, 2011this is a dual boot XP/UBUNTU 10.04. while using XP, the computer rebooted itself. the GRUB's screen appears, but neither the ubuntu nor the XP option works.
Ubuntu gives this error message:
Code:
0.797795 kernel panic-not syncing: vfs: enable to mount root fs on unknown-block (0,0)
XP hangs on a black screen... and that is it (thanks for support windows!) UBUNTU 10.04 live CD hangs when the 5 processing dots appears bellow the ubuntu logo. hangs the same way with the processing bar in UBUNTU 9.04 live CD. memory check (memtest86) is showing thousands of errors right from the start.
Ubuntu :: Computer Booting To System Memory Test In Grub Menu?
Feb 20, 2010I'm very new to Linux but when I first installed it, I downloaded the Start-Up Manager so I could change the boot order. I have a dual boot Windows-Linux, I set the default as Windows. Recently my computer started booting to the system memory test in the grub menu instead of Windows. When I try to open the Start-Up Manager now it asks me for the password as usual and then does not start. How I would change it back to windows for the default? I'm running Ubuntu 9.10.

View 3 Replies View RelatedOpenSUSE Install :: Virtual Memory / Resident Memory Of Server?
Feb 3, 2010we found that if we use 'top' to show the memory usage of a server (SuSe Linux 10), we can get virtual memory usage as well as 'Resident memory' usage. For virtual mem or a particular process, it is around 1.1GB, which is large but for resident memory, it only consumes 300MB. Are there anyone who knows what the differences are? I would also like to know whether the difference (1.1GB - 300MB) = 800MB are actually available for use by other applications in the system.

Apr 9, 2011I'm a web developer and I am building a site on a CMS that has issues moving from a WAMP server to LAMP. The live server is LAMP and I am running Windows 7. I don't want to run into problems moving from the test server to the live server, so I was wondering if I could somehow run Linux using a virtual machine (using Windows Virtual PC which I think supports Linux or VirtualBox) and then using a Linux equivalent of WAMP2 server as a test server. how to do this and what the best Linux distribution to use would be?

Nov 18, 2009I did command:

And now I cannot login on my test server notebook. Please do not ask why I use server software on my notebook. Cause I like it and I use it only for typing text en learning linux commands. So I have a notebook with ubuntu server 8.04.2.
First question is:
Why have linux after command ls -l -a this output?
drwxr-xr-x 21 root root 4096 2009-11-04 20:45 .
drwxr-xr-x 21 root root 4096 2009-11-04 20:45 ..
And how must it to set and use? What is it's function? How can I repair my server notebook? Must I unmount my harddisk with a sqrewdriver and connect it to/on an other linux machine? If its needed, I can do that.

Using yum I installed vsftpd and ran into problems, thinking it was something I might of done I did a fresh install of CentOS and I still recieve the same problem on a fresh install so it is nothing I have done to the server.
The problem is when connecting via a sftp client I get an out of memory error. This error is listed in the putty faq ( url ) under A.7.5, there is a brief explaintion of the cure under A.7.6.
there is mention of a login script but I don't know where this is located. I'm a novice at Linux but by no means incompotent when it comes to computing.

I've done an extensive google search about the issue and it seems not uncommon. I ran a memtest with no errors returned, so I'm sure that there's nothing really wrong with the memory; apparently it's a bug in the kernel that's causing this.
