Hardware :: Wrong RAM Memory Information At BIOS
Nov 4, 2010
I have 4GB RAM installed on my PC (ASUS P7H55M-BR, Intel i3 530 2,93Ghz). Onboard video has 32 MB (BIOS config).
It should be this way (or maybe not?):Each slot has 1GB of RAM memory: 4 x 1024 MB = 4096 MB.
Now, subtracting the video memory: 4096 MB - 32 MB = 4064 MB.
It's working on Dual Channel.
But when I am booting the system, the BIOS shows only 3920 MB (3,9GB). Linux shows even lower: 3881 MB.
Memory Remap Feature is enabled at the BIOS config.

is there a way to retrieve the processor model without taking information from bios? I don't know which processor is really mounted. I want to set up the right processor timing, but I don't know the processor type. Every time I change the timing for the processor in BIOS another processor type is determined (I should be an Athlon XP +1500, I think, but I don't know really).
I think with less /proc/cpuinfo the results depends on the timing that is set in bios. So could you tell me how I can find out which processor is really mounted?

I have an HP Compaq nc4010 laptop, with Debian experimental installed on it.In the BIOS utility, I can view what they refer to as "battery information".Unfortunately, it's all horribly abbreviated, so I can only guess what the labels mean.Is there any way I can acces this same information from linux, preferably with full labels and/or descriptions?

I'm not too sure if this is the right topic to post in but if it isn't please move it to the correct topic. I recently opened some ports for my Playstation 3 and the connection test on the PS3 tells me that the ports are open . But when I execute this command
nmap -p 0-60000 192.168.1.5 I get this
Quote:
Starting Nmap 5.21 ( http://nmap.org ) at 2010-10-16 20:54 AUS Eastern Daylight
Time Nmap scan report for PS3 (192.168.1.5)
Host is up (0.00063s latency).
All 60001 scanned ports on PS3 (192.168.1.5) are closed
MAC Address: **:**:**:**:**:** (Sony Computer Entertainment)
Nmap done: 1 IP address (1 host up) scanned in 4.12 seconds
I could be executing the wrong command or something but I have read through the manual and couldn't find anything that helped. I have tried this command on other machines that I have opened ports for and get similar results except for a few Ephemeral ports (80,443 etc.) which also makes me wonder why these aren't listed as open on the PS3?

System time was drifting ahead increasingly for several days time in the end. This is what I did with the clock about 6 hours "in the future":
Quote:
sntp -P no -r pool.ntp.org
hwclock --systohc
i.e. I got the (more or less) exact time from the time server and set the hardware / BIOS timer with this value.I renamed "/etc/adjtime" to beginn with a clean slate. During reboot (shut down phase) I noticed a message saying something like: "hwclock set to system time". I checked in the BIOS and there was a new time about one hour early(!). The boot phase then reset the time again, this time several hours forward (usually two to six hours). This is an iterating process, with a net gain of several hours per boot. It is not always whole hours -- like in a time zone error but it involves also minutes. System is set to UTC as affirmed by the "date" command. What could be the cause of this behaviour of the clock / timer?

I'm having a problem with xbindkeys giving the wrong mapping information, hence I can't get it work at all when trying new mappings from this machine. From another computer, I have some definitions for xbindkeys (made with xbindkeys-config). These key codes work correctly on this computer I'm having difficulty with. From the config file for example:

openSUSE 11.2 installed on machine with 5GB memory but System Information in KDE desktop shows only 3GB total memory. Just added a further 4GB but no change shown in System Information.
Is there something I must do to have sysinfo report true value and does this mean that memory not shown is not being used?
POST BIOS check shows 9GB installed.

A few years back when I was running Linux most of the time I used a program that gave me information on my machine.
It had different themes and such, and it would usually rest vertically along the side of the desktop. It would tell one information on drives, space, memory, I think you could even have it tell you the weather if you entered geographical information.
I know I'm being a bit vague but that's all I can remember, does anyone recall this program? It was pretty popular back then...so I wonder if it's still under development.

I have decided to load the OS on a old HP Compaq DX2000 MT to see if its for me before putting it on my main machine.
I loaded Ubuntu version 10.10 last night everything was fine except I could not get my wireless adapter to work, I decided to connect via ethernet to get the latest updates and drivers.
After the updates and restart I now get the non executable memory error. when I enter
/usr/bin/check-bios-nx --verbose
I am told I have NX capabilities and should go to the bios and enable it. There is nothing in
the bios to enable as far as I can see. So I enter the command
sudo rm /etc/update-motd.d/20-cpu-checker

as you should see, top is indicating 3.544.864kb (3.5Gb) of memory used while gnome system monitor only 609Mb. What's wrong here? (I am pretty sure Gnome SM is right. Top is updating every sec.)

I tried to install OpenSuse 11.3 on my brand new pc, which already had Windows 7 proffessional in it, and I went step by step through the installation without changing anything. It didn't work. I tried for a second time and this error message kept popping up: "Creating device modes with udev 2.0436224] [drm: i915_diver_load]*ERROR*Detected broken BIOS with 262140/2644kb of video memory stolen. 2.0436224] [drm: i915_diver_load]*ERROR*Disabling GEM(try reducing stolen memory or updating the BIOS to fix)"
And then a lot of letters and numbers wich make no sense to me. Now the only way I can initiate OpenSuse is with the OSuse boot dvd and on failsafe mode.

How would you make NIS user information override local user information on client systems? This is what I think is right? Add nis on the passwd registration file on the second line Is this correct?

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 C and linux. My code below does arbitary writes but I cant figure out where or how it does it.
I am calling the insertNode() function with seq = 'MISSISSPPI$' and alphabets = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ$'
Code:
Weird behaviour I should mention is that when I check for NULL pointer in node->child[index], the unassigned values are not null anymore, they point to arbitary memory.

we 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.

I am monitoring physical memory in a server I administer, and my hardware provider told me they had increased physical memory size to 4Gb... However, using several tools (free -m; top; dmesg | grep Memory; grep MemTotal /proc/meminfo I discovered that I actually have 3Gb, not 4... But, my doubt comes from the fact that dmesg | grem Memory tells me I have 3103396k/4194304k available The first number is effectively 3Gb, but the second one, is 4! so, why I am looking at this two different numbers?

I have had a fresh install of Ubuntu 9.10 and installed some software after that.Since third some, some process is eating half of my memory.I have checked processes running in system manager but everything is normal.Maximum is consumed by compiz which is about 26 mb, seems very normal.I did restarted my computer several times, and in the start for 5 mins, its fine after that again my cpu fans runs at very fast speed and my one cpu is used up 95 % (I have dual core).Please help me out, this invisible thing is driving me crazy.I am attaching my htop screen shot (sorted by cpu %), now the cpu is not used by completely but fan is still struggling hard and fast.

I am writing an application that wants to access periphals registers outside the standard (allowed) memory area.
Doing so gets me "segmentation fault".
I know, this is natural behaviour.
One way of getting around this is writing the module which has to be loaded by linux. I will consider this some time later.
For now, I want to come to some quick result and allow linux or gcc compiler to write to those memory areas of periphals. Is there a direct way to do so?

Is that possible that SHM shared memory is counted as cache memory on Linux with kernel 2.6.18?If find it really odd since this memory is not file backed, but I have a piece of code that loads data using shm_open+mmap, and it generates an amount of cache memory in /proc/meminfo that corresponds exactly to the amount of shared memory (I load that data from a file but I am using posix_fadvise(fd,0,0,POSIX_FADV_DONTNEED) to ensure this file is not cached and I made sure that it is working as expected). As far as I know SHM memory was not tagged as cache memory with kernel 2.6.9.If it is the case it is really unfortunate since normally cache memory can be considered to be part of the "available" memory since it can be flushed promptly but this is clearly not the case with SHM memory... Is there an easy way to get the total amount of used SHM memory on a system?

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.
