Can someone tell me why do i get different values of RAM on DXDIAG and on CPU-z-123?

Your computer is apparently using 64MB for the video. Different programs will read this differently...Either the full amount of physical memory or the amount of memory left  after the video hogs it...

I do not believe that you gave us the complete model number.  The D series goes to 4GB and has 4 slots for DDR RAM. \n\nLook your exact model up at \nhttp://www.18004memory.com/\n\nGood luck and Happy Computing!

Here's a few things you might want to think about:\n\nPress {windows} and {pause break} and see if it's reporting your full memory amount.  \n\nWatch the performance tab in task manager and watch your memory usage as you copy and paste.\n\nAre you managing your swap file manually or do you let Windows do it?  \n\nAlso, try running memtest to check your memory for errors:\n\nhttp://hcidesign.com/memtest/MemTest.zip

what is it?   When all the RAM is being used (for example if there are many programs open at the same time) the computer will swap data to the hard drive and back to give the impression that there is slightly more memory.\n\nThe best thing to do is to buy more memory, not the most cost effective, but the best.\n\nIf you are running XP, you can also goto start->run-> "msconfig".  Click on the startup tab and there should be a bunch of junk such as OEM software, just look and play around.  make sure you don't turn off spyware, virus, or firewalls.

Naah...not the fan...First of all..why did U reinstall XP?\nFor a CPU like that...256ram is kinda low...get atleast a gig for a good speed!\nU might have some harware issues...look at all the drivers installed...Then check the IRQs...there might be some conflict which is taking up resources!\nHope this helps!

I don't believe you have a RAM  issue, I believe you're overtaxing your processor.  Depending on the type of processor you have, you can only accomplish so many tasks at one time.  You also might have too many background programs running at one time, on top of the programs that you initiate.  Download the program I have supplied a link for below, and find out exactly what's running on your system.  Turn off anything that's not system critical this should free up some processor time.

1)Battery flat\n2)Bios/cmos setup not performed properly. (all hardware not registered.\n\nIf it's an older PC also check parity/non parity setting in bios. If your system requires parity, then non-parity DRAM will not work.

First of all, make sure that you are getting the right type of RAM (DDR MHz, DIMMs/SO-DIMMs, ECC/non-ECC, buffered/unbuffered). Be aware that some motherboards require paired RAM modules of the same type and/or size. All of these properties can cause the price of RAM to vary.\n\nThe next property is the CAS latency, or how many cycles the RAM has to wait before between column access and moving data. The lower CAS rating, the faster the RAM's response, and the higher the price.\n\nLastly, name brand RAM costs more. But as you might guess, this is the least important criteria. The only advantages of name brands are better overall quality, and they are burned in and tested before being sold.

Nope, it is not, it runs in parallel, for instance  333 DDR DC runs at 133 MHZ through two channels, for a total of 266 MHZ.  It is over clocked to output 333....\nKeep this in mind:\nWhat are some of the benefits of using paired memory? Since the memory sticks are packaged together after they have been tested together makes sure the modules that the end-user receives will be stable and perform well. Mixing different memory could lead to system instabilities or the memory modules might not run together due to compatibility issues. This takes the guesswork out of choosing memory for a dual channel motherboard. In addition, we feel that since memory speeds are not getting much faster, this give memory manufacturers another stepping-stone before moving to faster memory. Recently many other manufacturers have also started producing these paired memory kits.

1. to allot more ram to graphic from your total ram, in the bios startup, choose the graphic option, then try to allot the highest ram from the available option. but this usually has fixed to a maximum 128 mb for graphic.\n\n2. increase your virtual memory. right click on my computer, go to properties, go to Advance tab, under Performance, click on Setting, go to Advance tab, you will see there a option for Virtual Memory on the bottom side of the windows, and there will display the current virtual memory set in your computer. then u click on change, set your initial size and maximum size of virtual memory and then click on Set. click OK, to close all windows, and then restart your computer. after restarting, check back your virtual memory by click on properties on my computer again.

I suspect your memory chip is failing as this is a fairly typically tell-tale. If none of the 'conventional answers work' do a Google for MemTest, download the program, run it. (The app creates a bootable CD which will list in bright red any errors)\n\nAdditionally, and even before the above, check your CPU heatsink is not too hot to touch. If it is, replace the CPU cooler (quite cheap at a computer shop - if nervous, ask them to fit it as you can screw things up royally trying to get the old one off)\n\nGood luck. In my experience, this problem has absolutely nothing to do with HAL.DLL or MUP.SYS (the other close favorite which cheats you into thinking there is a software issue)\n\nOf course, I could be wrong.... Naw

you havent specified how much you have and how much it shows, normally the ram will be shared for vram(video ram) also, like if you have 128mb , shared 32mb or .... will be reduced and showed in the system properties tab, because while upgrading and all the ram wont be reduced

Sounds like an all to common memory issue.\nTry Memtest86: http://www.memtest86.com/

Some of that is old stuff.\n\nSTAT II is the up and coming thing instead of ATA 100\n\nWhat is the RAM?  DDRII?  That's new, also.  DDR is old and SIMM is ancient!\n\nThe CPU is 64 bit ready, correct?

Run dxdiag. It should tell you about the RAM, CPU, OS(and build), and the DirectX version.

PC100 and PC133 are backwards compatible.  Download a free utility over here, http://www.cpuid.com/cpuz.php it will tell you what kind of memory you have along with processor information and other tidbits about your system.

A few things... 1) The chip may be defective 2)The mother board in your computer doesn't support 512MB sticks.\n\nDoes the system start up when the chip is installed? If it does you could use a program like MemtestX86+ to test each chip.   \nYou may also want to check compaq's website for any bios updates that may help the computer.  \n\nFinally, PNY's memory configurator is a nice help for figuring out what your system can handle.  It will give you details about the motherboard, like how much ram is supported, bus speeds, cpu speeds, etc... Granted they will recommend PNY memory products, but their product model numbers give away the specific type of memory they are e.g. PC100, PC133, etc..
