General :: Windows 7 - Order In The Slots Of Memory Modules Matter/ MemTest?
Apr 4, 2011
In a new PC I had constantly BSoD. I tracked it down to bad memory modules and took them back to the shop.Specifically the RAM was Corsair. Anyway they said they will do test on memory to confirm. They did tests and admitted the RAM was faulty and gave me a replacement. At this point: originally I bought 2 kits of 4G RAM. One of the kits turned out bad. They gave me a replacement, it does not seem to be exactly the same, though. In any case, I became causious and as soon as I got them I put them in the PC and run KUbuntu memtest. It started showing thousands of errors! (Again!). I removed the new kit and run the test again. No errors. I swapped the slots I put the memory modules and also no errors. I can not understand now. Is the new RAM kit bad or not? Does the slots I place the kits matter?

Command top displays the pids (tasks) by order of CPU usage. Could I make it order them by memory usage?

In my office we sometimes have servers that hit the max_connections limit. As we sometimes have scripts that take up that 1 extra 'superuser' slot for MySQLD, we'd like to raise that. Google really hasn't turned up much on this, is there a way to raise the number of slots?

I included this screenshot for clarity: The triangle is (according to my logic) wrongly rotated. Is this a bug, or an intentional choice?

I've been trying to load my pcmcia network card driver "xirc2ps_cs" at startup with no success. I have added "modprobe xirc2ps_cs" to the rc.modules file but it doesn't load at startup. Curiously, though, if I execute rc.modules AFTER the machine has booted it will load the modules just fine. Just not during the boot up process. Thinking that hotstart might have been causing problems I've disabled hotstart (chmod -x) temporarilly to remove it from the picture, but there was no change.

It's quite easy to change the default boot entry through etc/default/grub. However, this only allows for the first entry to be changed. I want to be able to move all the entries in any order I like. What is the best/easiest way to do this?

I have some playlist I want to keep the songorder, but I have the files in another file-structure.( I have the songs ordered in folder by artist and album, cos all songs are note tagged correctly or in the same way.)I want to use the playlist with the songs in copied to an another plays, for instance an usb-stick.Is there an application who fix mass change of all links to the songs?
for instance I have in m3u-files:
#EXTM3U
#EXTINF:268,Salt Fare North Sea[code]....
Or Is there a way in Amarok or another music-player that can make a copy of the playlists song order and use it with new links on a usb-memory? I don't now how sync to media-player and such things work.

Bought computer 11 months ago, immediately there were problems. What would happen is, when I logged in after a long period of shut down, the system would BSOD. Then I would restart and everything would be fine, until the next time I shut down for a long time (8ish hours) and got back on. I sent the laptop in (a couple times) and they eventually replaced the RAM and the BSODs went away. This is all on Windows 7 (well started on Vista, switched to Windows 7).
I recently set up a dual boot with Windows 7 and Ubuntu 10.04. I'm experiencing crashes on Ubuntu (the whole system just freezes, can't operate mouse, keyboard, or anything) and the behavior is similar. When I log on after a long period of shut down, the system will crash, but if I restart (actually I have to wait 10 minutes before I restart, if I restart immediately it will crash again) then it is fine, until the next period of long shutdown.
So I'm thinking it's bad RAM, so I downloaded Memtest and am testing each of my sticks (they are each 2GB) individually in the same connector thing (don't know what it is called, whatever the sticks attach to). The test for the first one passed with flying colors. However, the second one is having problems. On test #2, the memtest repeats itself, continuously looping through 0-32767 errors on the right side.
My laptop is an Asus G50VT
The 2 most interesting lines...
Highest Error Address: 000fffffffc - 4095.9 MB // does this make sense? 4095.9 MB on a 2GB stick?
Test 2: 32767 // the 32767 loops back around to 0 and repeats

It seems that the canonical instructions for making a bootable USB flash drive that runs memtest are at:
[URL]
However, after following them to a T, I boot up the new machine and get:
"could not find kernel image: linux"
Do I need to set up a lilo.conf first?

I have a 16GB memorystick which used to have a Linux partition. It therefore has two partitions; 2GB FAT32 and 14GB linux boot drive. The linux part stopped working, so I decided to reinstall it. But windows can't see that partition. I tried formatting the whole disk, but I can only format one partition (the FAT32). There seems to be no way to combine the two partitions into one big one, and there seems to be no way for windows to partition the large part of the memorystick to but Linux on it. In the windows partition manager, windows sees the large unused partition, and it let me delete it. But once I have deleted it, I'm not allowed to format it. Also I cannot delete or resize the small partition. I have a memorystick with two partitons. Windows only sees one of them, and won't let me use the other one. I would like to combine the two partitions so I can install Linux on the memory stick again.

By default, when applications run, they are limited in the amount of RAM they are allowed to access right? Technically my VLC could not access memory addresses used by Chrome. But how is it possible for the operating system/compiler to mistakingly allow access to an address a code is not allowed. I know alot of 'exploits' and 'payloads' take advantage of this fact and create variables that take up too much space and 'overflow' into other addresses, but how does this actually happen?
Are some programs more prone to this than others? Does it matter in which language they are coded in? For example, I know C is allowed to play around with memory, while Java is not. Also, what are the advantages of this? What if someone wrote malicious code to access someplace in memory, what could they do? The only thing I can think of is passwords/keys stored in RAM.
PS I thought about putting this in Stack Overflow, but my question is much broader than just specifically related to a programming perspective. If I've placed it in the wrong place, I'm sorry.

I am using malloc and frees a lot in my program. It shows its allocated but when i remove it doesnt show as the memory is removed(I am using the top command to view VIRT memory usage). If this continously grows what would happen to my program (Will it go out of memory?)

I have a computer with 16GB of ram. At the moment, top shows all the RAM is taken, (NOT by cache), but the RAM used by the various processes is very far from 16GB.I have seen this problem several times, but I don't understand what is happening.My only remedy so far has been to reboot the machine.

I am new to Linux, but was put in charge of our company's Amazon presence. My problem is that all of the sudden, a shell script we have been using has stopped working, and returned an odd error that I simply can't decipher. The shell script is pretty simple, and is run on our crontab (however manually running it causes the same error as well). The script name is "sendh.sh" and to run it in Linux is simply typing "sh sendh.sh". Here it is:
[Code]....
Yes, obviously those files are in the directory, I can see them through the "ls" command (or through WinSCP as well). When run one by one, each command works fine, it's just when using this "sendh.sh" shell script then it fails. Does anyone know why "" is appended to the filenames when I try to run it, or what the heck "ambiguous redirect" means?

In F11, I could configure windows to gain focus when the mouse hovers over them ... it was possible to finetune the response in terms of seconds. I dont find the menu item for this function any more in F12 (System -> Preferences ->?) Which package added that functionality and is there a version for F12? I really miss it
just noticed that the windows are already set to respond that way (by default) only that the title bars don't indicate a change in focus.

This is my first post in these forums. I'm still quite new to Linux (using Mint 9) so please bear with my not-very-articulate question(s)When I boot up and open up a tty terminal I get a message saying "Memory corruption detected in low memory." 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.

I found from command 'top' that 8GB memory are used. However, using command 'ps' with some options to grep the running processes and then summing up the memory used by the running processes are less than 2 GB. Where has the used memory gone ?

Similar to this: How to "hibernate a process" under Linux/Windows? Are there any methods to hibernate a process in a way that it doesn't stay in memory? E.g.: If I don't want to use Firefox, and don't want to close the process of it, and I need free memory, then how can I really hibernate the process so the memory reserved by Firefox is freed up? I need solution for both Windows and Linux!

Tonight I installed ubuntu 10.10 (32 bit) on an external usb harddrive with a dvd I burned and I used my older desktop. I disconnected all internal and external drives first so everything had to be put on the usb drive I selected (only option available). I used the option to load extra software, use the entire hard drive, and let the software do it's thing. I basically had no options where to put things and it didn't have much choice.
When I boot the usb drive on my laptop (win 7 64 bit) by telling the bios to boot to it first... I get an error: modprobe: FATAL Could not load /lib/modules 2.6.35-22 generic modules No such file or directory. This message appears twice and then it does boot into ubuntu and seems to work fine. I'm new to this OS so that is an uneducated guess but the things I have done seem to be working. So exactly what is this error referring too? Is there a way to fix the problem or do I just ignore it.

Ubuntu 10.04 I am dual-booting along with Windows. I need to change the order of boot options so that Windows is the automatic selection rather than Ubuntu. I cannot find the file to make the change and not sure what changes I should make when I do find it .

In Windows 7, the options are pretty nice - ability to change track name, artist, composer, album, song number in album, etc., all from "Properties." In Ubuntu 10.10, Properties really gives you the bare minimum. Is there a program to download in order to get the same sort of basic options as one does from Properties in Windows 7?

I am having problems installing linux on an old PC with the hard drive shredded, old CD drive, old 1 GB RAM card. I want to make sure the problem is not that the memory is partially bad.I recall that there should be some way to get the BIOS to test the memory overnight, but couldn't find this mentioned in the books I checked or in my notes. I believe that the motherboard is made by ASUS, if that helps. When I power on and hit the delete key, I do get some BIOS options, but memtest is not mentioned.
