Question about Computers & Internet

1 Answer

All my RAM is being used.

From time to time (quite often) my memory gadget shows that 100% of RAM is used, but almost no CPU. At these times I can do nothing, even the cursor hardly moves. Restarting Windows usually results in the same problem. Eventually it stops, but I lose hours of work. How do I track down what is stealing all my RAM?

SOURCE: dual channel problem

Is the 2 GB of memory in two identical 1GB sticks? what slots are they installed in? Check to make sure they are installed in slots 1 and 3 (usually - I dont know what motherboard you are using.), and the motherboard is enabled to dual channel mode .

SOURCE: Freezes up after short time.

This is probably an over heating CPU(processor). Make sure the fan over the processor is working. If it is, check to see if the heat sink is fastened properly to the motherboard - if you can push on any of the corners and it moves in than there's an issue.

Also look for a thick layer of dust that might be blocking the air flow.

Has the motherboard got a new BIOS battery?
Check the voltage of the battery, if it is a lithium battery CR2032 then the voltage should be 3 volts, if it is less than 2.98 volts then replace the battery.

My pc is to slow how can i speed it up?


First, try some diagnostic work.
  • Go to the Apple menu and open "About this Mac." Verify that it shows the correct amount of installed memory. (My Powerbook was unusually slow one day because a memory module needed to be reseated; it didn't have enough RAM available, so it was running quite a bit out of virtual memory.)
  • Next, open Applications/Utilities/Activity Monitor. Click on the Memory tab ato see how much free memory you have. If there is little or none, look through the list of processes running to see what is using memory. Background system processes generally do not use more than 15 Mb; applications can use considerably more.
  • In Activity Monitor, click on the CPU tab. If it is running at 100% most of the time, and you have no applications open besides Activity Monitor, your system may be infected by a Trojan Horse spammer. You can confirm this by checking Network activity; if it is busy without Mail or a web browser running, and Software Update is not active, this is likely "enemy action."
  • If you have a combination of low CPU activity, very little free memory, and a very busy hard drive (check Drive Activity), you have too much stuff open for the amount of installed RAM. Quit your web browser, (you can reopen it again when you need it) and try to avoid having so many tabs or windows open. If you have a large amount of mail in your inbox, it's time to catch up on archiving or deleting older messages - a large inbox needs a lot of memory to run.
  • If you are running a massive Photoshop process in the background while watching an internet video, the CPU will be running at maximum speed, and sometimes it will get a bit behind on the video. There isn't much that can be done about it except to wait; photo rendering is inherently computation intensive.
  • Make sure the cooling system is running properly. Some systems will slow down if the processor gets too warm to avoid overheating. Others simply wait until the temperature hits a limit, then shut everything down (oops - there goes all the unsaved file work ...). I don't know how the intel PowerMac handles overheat conditions, but it may be the former case rather than the latter.

My Intel D945PVS motherboard has become very slow. I tried to add memory (4g) but no help. I think it could be the motherboard or cpu. I see the cpu running at 100% a lot of time. Can you help.


I will suggest to see running processes. It will show you what processes are running and which uses more memory (also cpu usage). It might be some virus or unwanted program.

Blue screen of death, cant seem to be stable after trying everything . thinking it may be a memory timing issue, using 4 gigs of drr 500 mushkin redline. will give further discription if you tell what info...


It could very well be the timing but it may also be the voltage setting. find the specs for the memory from their website, timing and voltage and enter your bios and make sure the voltage is set to the right parameters. The timing isn't as critical as correct voltage. I also wonder if changing the memory positions may be causing the error. My mother board made me use slots 3,4 not 1,2 kinda strange but when I switched them no more bsod. And remember windows 32bit systems will only use/show 3.2 gigs regardless of how much physical ram is installed. I hope this helps you and good luck.

Ddr ram sdr ram i am same time input that tw0 thats not show two ram capacities just show one ram'' asus p4s533 model please help me


Hi safran0785,
The Asus motherboard, P4S533-MX can run two different types of memory.
(Just not at the same time & in different slots).
You can use 2, 184-pin memory, PC2700/PC2100 MHz or PC1600 up to 2GB. (1GB DIMMs) inserted in the two memory slots closest to the CPU.
Or you can run SDR memory, 168-pin PC133 or PC100MHz DIMMs up to 1GB of memory in the last two slots farthest from the CPU.
You can not run both types of memory at the same time.

The 184-pin DDR PC2700MHz memory is much faster then SDR memory.
The maximum amount of system memory supported is 2GB.

Need more information/questions, just post here.
Good luck safran0785!
Mike

Boot your PC into "Safe Mode" (tapping the F8 key on boot to get to the option) and run a full/complete Virus scan with Anti Virus with up to date virus definitions and see what that yields.

RAM


You may have bad or incompatible Ram . Verify that the memory you have is compatible. .

Machine name: Dell Dimension 3000
CPU options: Intel Pentium 4 or Intel Celeron
Chipset: Intel 865GV Chipset
HD Bus: Ultra ATA/100
Front Side Bus options: 800MHz FSB
Memory Speed options: PC3200 DDR400 184pin SDRAM DIMM
Special notes: The Dimension 3000 has two different bus speeds each of which takes different memory. You cannot mix the speeds.

Take the memory out and install one at a time. This way you can verify that the memory is indeed working. If you find a bad one, replace it.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Few questions about RAM memory?


Solution:



i)  LOW DENSITY modules have 100% compatiility with ALL systems and ALL chipsets.
    HIGH DENSITY modules only have 10% compatibility

    here compatablity means LOW DENSITY RAM are accepted by all system(100%)  or any make           system.. HIGH DENSITY RAM are accepted by 10% by only some system or computers...


ii) in order to check system performance or amount of Computer RAM usage press the ctrl+alt+del
   simultaneously a new window(window task manager) will appear showing:

    CPU usage: showing the amount of CPU or processor utilized at that particular time.
    PF usage: showing the amount of RAM memory utilized at that particular time.
    Physical Memory: showing Total RAM Memory, Available Ram memory....

iii) baiscally they are two types of RAM they are:

    DDR1:which is older one supported by older system  or older mother boards which is costlier
    DDR2: which is latest one supported by all new system or new mother boards which is less                         costlier

    DDR: double data rated ram......which will send data at a double rate compared to SD RAM

iii) here color doesnt matter, these slots either support DDR1 or DDR2 but not both at a time
    
    DDR1 has 184 pins or gold plated pinssss... on the edge of the RAM
    DDR2 has 240 pins 

    so difference doesnot allow DDR2 to placed in DDR1 motherboards or vice versa...

iv) it does have anything to do with no of chips on the RAM but they only differ whether it is DDR1 OR DDR 2(DDR2 are much faster than DDR1)

NOTE: whatever may the the RAM, each RAM has FSB(called Frequency...) which determines the frequency of rate at which data is tranferred from RAM to processor(CPU)  usually in MHZ such as FSB 300, 400, 200 , 333...................

more the FSB the faster data is transferred to the processor(CPU)

dont worry even RAM with less FSB's work well with the processor....having 1 GB RAM or 2 GB RAM is engouh, it only matters with the speed of CPU ... but not RAM......

Stop start performance


Sounds like NOD 32 is causing a few issue, It tends to update itself quite often and tie up almost 100% of CPU time when doing this. I would try uninstalling this this and trying a different firewall that isn't as resource hungry. I would recommend Comodo AV and Sygate or Comodo Firewall, These are all free and available for downlaod from the web, They also use very little CPU and Memory and always prompt before installing updates etc. Hope this helps.
