KDE vs Gnome vs XFCE (amount of ram used.)

I run the command:
coda ~ $ free -m
total used free shared buffers cached
Mem: 2010 1341 669 0 78 890
-/+ buffers/cache: 373 1637
Swap: 1474 0 1474
So I'm using a total of 373 megs of ram on KDE.
I have an old laptop, and I want to know if I have enough ram to run gnome without excessively using swap.
And if not, I'll just use XFCE.
How much RAM (on average) does Gnome and XFCE use?

I don't think you'll find any with meaningful figures, and the figures here aren't all that useful either. I mean, even comparing memory usage between two different users with the exact same programs running and the very same hardware will give you very different results unless it's measured directly after a cold boot (and the numbers you'll get then is meaningless anyway), seeing as usage patterns will have a major effect on how much memory any application will use.
Agreed.
What is also not being taken into account here is kernel modules loaded.
Unloading unused modules may reduce significantly, the amount of used memory (i.e. free up memory)
Note the +/-buffers line presents the (used and) free mem available to applications.

Amount of RAM useful limited to processor speed?

I have heard that at a certain point the amount of RAM you throw in your computer won't help past a certain processor speed. If this is true, is there a chart out there that will show these limits?
Or if anyone has any opinions as far as a:
Dual 2.7Ghz (G5)
Dual 1.8Ghz (G5)
Dual 800Mhz (G4)
all PowerPC
thanks,

Without a list of applications, you could be starving your apps, especially if they need to be open and active. If you work on large photoshop files and not smallish, it is impossible almost to have too much (and you would need a PCIe G5 to get 10-12GB RAM).
Check page-out; number of swap files; whether you are generating swap files.
just scanning and retouching can eat up 2GB RAM.
OS X uses free memory to cache windows, disk I/O, and those won't show up looking at Activity Monitor.
Virtual memory can be 'requested' or 'allocated' but not used, too.
I saw people with 512-768MB be shocked at what a difference even light use (email, web, writing, etc) it was to upgrade their G5 to 1.5GB RAM. There are also programming changes that go into a G5 that are totally different from G4s.
But it has nothing to do with cpu, front side bus.
And no matter what, a nice fast 10K Raptor boot drive always helps

I AM STUCK WITH MOZILLA FIREFOX / NOT SHOWN ON MY LAPTOP SCREEN / USING HUGE AMOUNT OF RAM IN GENERAL - CAN YOU HELP????

Hi,
I have copied these problem on you site, as I could explain better then what they did, wich my problem remain the same as they have. And part me explaining what is really happen to my Laptop.
''Mozilla/Firefox 4 will not SHOW on my computer SCREEN.
Firefox won't load onto my computer. I have Windows 7, and each time I try to run the program to install it, it tells me I have another version still waiting to be installed that requires my computer to reboot. When I check "yes" to reboot, my computer reboots but still no Firefox. When I try to uninstall the the old Mozilla program from my Control Panels, there is no Mozilla files or programs listed not in my list of programs but when I go directly to the Windows File on the C: Drive, there's a Mozilla program file there. WHen I go into that file check, I attempt to open the uninstall program. I get an error message that says something to the effect of: "the version Mozilla on this computer is not compatable with my OS." Something about it being and 86bit program. My Firefox 3.6 worked fine 2 days ago. What's wrong??? ''
'''Firefox 4 using huge amounts of RAM on sites with Java scripts
I have been observing Firefox using huge amount of RAM when I am on sites that use Java Scripts to rotate images. I have tried a couple of different sites and have monitored the RAM usage. With Java script enabled Firefox 4 continues to grow its RAM usage by about 10MB a minute. I have had the usage hit as high as 1.5GB. As a comparison I have monitored the same sites in Internet explorer and have not seen the same issue. - Just to eliminate a site issue.
Turning off Java Script solves the issue and eventually frees the RAM.
I am using XP Pro, 3 GB RAM. '''''
My experince with Mozilla Firefox:
Here what really happen when I install the Mozilla Firebox on my La[top you can see the file is there but when I click the program to open its does not shown on the screen but when I check with WTM (Windows Task Manager) its shows that is ON and you can only witness the laptop going very slow and I have to reboot it, and I can not install any other Mozilla :( because of the same problem and all the above.
I really need Mozilla to work as soon as possible due to important deadlines I have pendent, and i can only use Chrome but is not my ideal program. Can you help me , please ?????
Thank you

How to find out the amount of ram a computer can hold

I want to know how to find out what is the max amount of ram my computer can actually take advantage of, rather than tell you my model and you tell me what is the max because I know it varies according to the model of the Computer
But if you'd like to help the other way, here is my model: Macbook(13-inch, Mid 2010 [unibody]) basically the latest version of the white macbook.

Pointdexter11 wrote:
simple version: what algorithms do they use to figure out the max is 8GB
That is not a simple question. I don't think anyone here knows the exact testing process that Apple uses to determine what the max ram will be at the time of release. This is done during the development process.

How to install KDE and Gnome

Normally I'm a big KDE user, but there are some things in GNOME I want to try out to see if I might make the switch. I already have KDE installed, if I wanted the option to run KDE or GNOME can I just 'sudo pacman -S gnome gnome-extras' and it'll show up in the session type for kdm?

i run gnome BUT like a bunch of kde programs
so both are installed
kde dose have a tendency to reset the "open with" defaults
then there is an option in kdm to run gnome,kde, or other
so it is not a problem at all , you might need to re set the "open with" defaults but that is about it.

Is There a Maximum Amount of RAM Loaded Per Core on the Processors

I hope I'm asking this question in the correct group.
We use AutoCAD Civil 3D which only uses one core of a multicore processor.
We seemed to have reached an impasse with AutoCAD and Windows with RAM usage. It appears that Windows will only load a maximum of 15.8GB RAM into the first core of a Intel Xenon or Intel I7 processor.
We have a rather large drawing that is roughly 48GB in size. This drawing opens on all the tested systems in about 33 minutes on a xenon system with 16 GB RAM, xenon system with 32GB RAM, I7 system with 32GB RAM and an overclocked I7 system
with 64GB RAM. The OS is Windows 7 64 bit and Windows 8.1 Pro.
Watching the resources on all the machines during the drawing opening the network throughput varies from 100Gbps to 500Gbps and when the first core reaches a maximum of 15.8GB RAM the throughput drops to around 72Kbps! These results are almost identical
on 4 different setups with RAM ranging from 16GB-64GB.
The 16GB system pulls all available RAM, 32GB and 64GB systems would only pull at the most 15.8GB to the first core.
Is this 16GB core limitation a Windows issue or an AutoCAD issue? AutoCAD is telling us we may have reached the core limit in windows.
Regards.

Hi，
As I know, there are 3 factors that limit the highest RAM amount your computer is able to see: 32 bit or 64 bit CPU, RAM limit of OS and RAM limit of motherboard. for CPU, 32 bit CPU can only has a limited 4 GB RAM, while 64 bit windows can has more RAM,
depends on the Windwos Version (you should also exclude some RAM used by audio\video\network memory). and motherboard manufacturer is the important one who decides the maximum RAM amount that can be supported, the only sure way to know is to consult your motherboard
manual\view the manufacture website\contact the manufacture.

KDE (or GNOME?) non-latin chars input problem

After recent upgrade (pacman -Syu) can't anymore type non-latin characters in GNOME apps (like gEdit, Evolution, Thunderbird etc.) under KDE. Openoffice is still OK.
Keyboard layout switching works (can see the difference between US and GB layouts, but when switching to non-latin layouts getting latin chars instead of non-latin.
In KDE apps everything is fine.
Have current KDE and GNOME installed.
BTW, when trying to run Epiphany web browser (under KDE again) getting error message (not sure but maybe this is related to the first problem):
"Could not start GNOME Web Browser
Startup failed because of the following error:
Unable to determine the address of the message bus (try 'man
dbus-launch' and 'man dbus-daemon' for help)"
Have dbus in DAEMONS line in rc.conf.
Any suggestions?

Fixed first problem... rollback of inputproto and libxi did the trick (not sure how safe it was).
scarecrow, thank you for your reply but it didn't help for the second problem. Changed DAEMONS to hal only, added dbus-python and even dbus-sharp (just in case, all other dbus related stuff was already there) but - no luck. Perhaps dbus-1.0 might be a solution who knows.
Thanks anyway.

Whats the maximum amount of RAM can I get/use for my iMac?

I own the
iMac (Anodized Aluminum) 1st Generation - Summer 2007
Anodized Aluminum Summer 2007, 20-inch with 2.0+ Processor
and I was wondering what THE MAX AMOUNT of RAM I can install into it is?

It can take 6GB of RAM; click here for installation instructions, and pick a vendor which advertises compatibility with your iMac model.

Maximum Amount of Ram

I recall reading, somewhere, something that gave me the impression that there was a limit to the total amount of RAM that one can have in a MacBook Pro, and any computer really.
Is this true? And if it is, how can I tell what the maximum amount is that I can put in my computer, or if someone can simply tell me, that works too.

A recommendation for your consideration:
3rd Party sources have you remove the one or two 4Gig cards you have now in your MBP and replace with one(1) with their 8Gig card or two (2) of their 8Gig cards for a total of 16Gigs.
MBP has only 2 memory card slots on 17" MBP (early 2011)
Higher density RAM will be available hence even higher RAM options in the near future.
Big time question would be :"is this an appropriate "upgrade" from a cost-benefit perspective"!!
One wants to optimize NOT maximize in all choices.
Let 'er rip and...
cheers

What is the max amount of ram can I put in my Macbook Pro (2010 Model)?

In general, for best performance, it's best to match up the same size modules in each slot (2x2 in this case). However, given that it's only going to read 3GB, I'm not sure if that holds true here.

Although Apple states a maximum of 8 GB, OWC (macsales.com) has tested 16 GB, so if you want to install 16 GB, I'd go with OWC as they tested it and do guarantee their RAM to work with Macs.

[solved] gnome resets xfce-settings?

hi everybody,
i have installed both, gnome and xfce4, mostly using xfce4 atm.
whenever i log in to gnome and go back to xfce afterwards a lot of my settings i made in xfce are changed. this concerns gtk-theme including fonts, wallpaper, some panel applets and xfwm-theme. if i change them back to my likes and log in/out everything is ok until the last login to gnome.
i find this to be quite annoying but i can't find a solution myself so please...
EDIT: works again after deleting ~/.config/xfce4

hm... no ideas so far.
i would like to post error messages or something else that might help but i cant think of anything except that all versions are up to date (XFCE 4.6.0, Gnome 2.24.3)
fusion-icon uses different settings in XFCE and Gnome as well, is that normal behaviour?
thanks in advance,

Do I have to have equal amount of RAM in both slots?

I read somewhere that the new DDR2 RAM works differently and that you have to have equal amount of RAM in both the slots to see the power of it. Is this true?

swanusa --
I think GeNomeZ has it right.
The DDR2 SD RAM in the October 2005 revision PBs runs at the same 333 MHz speed as does the DDR SD RAM in the prior revision PBs.
I don't know what you mean by seeing the "REAL power" of the new RAM, but I've never heard that you need equal amounts in both slots with either DDR or DDR2 RAM to have it run at peak performance. Do you remember where you read differently?

Activity Monitor reports incorrect amount of RAM

I have an early '09 Mac Mini 2.0 Ghz. I bought a 2GB stick from crucial and installed it in the empty slot without a hitch, I was nervous, but ifixit was a great help. If I look at the "About this Mac" screen, it clearly now says 3GB. If I then click look under the system profiler, all is well there also. 1-1GB + 1-2GB for a total of 3. If I open Activity Monitor, under the pie chart where it is supposed to say the total amount of RAM installed on the machine, it says 2.75GB. What gives? This one really has me stumped. Strange thing is that if I add up the "free:" and "used:" from the column on the left, it adds to 3GB.
I check my other Macs, all 4 display the correct amount in activity monitor. 3 of them running Snow Leopard and 1 G4 running Leopard. I called Apple support and the guy I talked to was unsure, but said that I should call Crucial. Called them, and the guy told me he was CERTAIN that the RAM was fine if it was up and running without crashing, which it is. He said it would either not startup, or it would be crashing regularly. I downloaded a RAM testing software, recommended by the crucial guy, called rember. Ran it, and all tests passed.
A few months ago, shortly before installing the RAM, I was given an old G3 iBook. I wanted to put some software on it for my daughter and hooked it up via Target Disk Mode to my Mini. Soon after it was connected, I smelled an electrical fire. The Mini then shut down and the fan spun at max for over an hour, with no response to the power button and the light off. Eventually I unplugged it, then later plugged back in and restarted. It seemed to be working fine. When I tried to hook up a firewire HD, it wouldn't read it. Under system profiler it said "Unable to read Firewire Device" in red (first time I had ever seen color in the profiler!) letters. I took it to the genius bar and the eventually told me the logic board was bad. Week later got it back with a new LB. About a month later Snow Leopard came out and I then added the RAM and installed it. It had previously been running Leopard.
I know that somewhere along the line, there was an update specifically for '09 Mini's that said something to the effect of... to correct an issue with certain Mac Mini's recognizing certain 3rd party RAM. It was a EFI update!?! maybe!?! or some type of ROM update, I think. I installed that update and got the "Successfully installed" dialog box after restart. I am not certain that the "bad" logic board (TDM firewire issue) had anything to do with the RAM, or even if the issue was present before the new logic board.
Would a replacement logic board be the cause? Maybe I had done the ROM update on the Mini's old logic board, but the new one needs to be updated? Does anyone else have these issues with a Mini or even another computer? Or is it a bug in activity monitor?

You have to look at whether the specs state the GPU RAM is shared with main memory or not.
For example, for the latest Mac Minis, the spec states:
NVIDIA GeForce 9400M graphics processor with 128MB of DDR3 SDRAM shared with main memory
or
NVIDIA GeForce 9400M graphics processor with 256MB of DDR3 SDRAM shared with main memory
Compare to the high end iMac which simply states:
NVIDIA GeForce GT 130 with 512MB of GDDR3 memory
All current Macs use integrated GPUs that use shared main memory RAM for graphics save for iMacs with an NVIDIA GT or ATI Radeon GPU, MacBook Pros with the NVIDIA 9600M GPU, and Mac Pros.
On shared machines Snow Leopard is just more honest by noting that memory used by the GPU is not actually available for use by the OS.
