Tip & How-To about HP Pavilion a1410n (ER890AA) PC Desktop

Place Windows Kernel into RAM


It's a given that anything that runs in RAM will be faster than an item that has to access the hard drive and virtual memory. Rather than have the kernel that is the foundation of XP using the slower Paging Executive functions, use this hack to create and set the DisablePagingExecutive DWORD to a value of 1.
Edit the Registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ Session Manager\Memory Management\DisablePagingExecutive to 1 to disable paging and have the kernel run in RAM (set the value to 0 to undo this hack). Exit the Registry and reboot. Perform this hack only if the system has 256 MB or more of installed RAM!

is it worth upgrading the 500MB memory of a 4 years-old Acer aspire laptop? its used only for web-surfing and emailing purposes.. no downloads..


You BET! Max it out when you buy the RAM. This is where all of your open OS files and running programs reside when the computer is on and running. It is very fast live memory - and when it fills up during use, anything else that cannot fit goes back to the hard drive in whats called "Virtual memory" or "swap file" - significantly slower.
I can say with certainty that if you max out your ram everything will work much faster! and that hourglass will become a scarce event.

Virtual Memory Problem


Virtual memory is a paging file setup on your hard drive. It reserves a spot on your hard drive to use in place of ram memory. You should be able to safely set it to 4096. You don't want to use too much as your computer will use what is available and it's faster to use actual ram memory than virtual memory. I'd leave the min. at 1536 and set max to 4096.

I installed this program for my relative for SAT exams, but once the installation is complete this window pops up saying that I need "at least 3MB of virtual memory space to run this program. But when I right click My Computer> Click on Properties> Go to Advanced Tab & click on Settings under Performance> Click on another Advanced Tab & "change" my Visual Memory. I have a Min. of 1536 (MB) & I'm allowed a Max. of 3072 (MB). But before I mess with this I want to know how much I can lower my Virtual Memory & what the risks are? I'd very much appreciate any solutions you might have.


I had same problem on my new XP Home Edition . It's got 1GB of RAM and I reckon the software is just comparing the raw numbers i.e 1 is less than 3 so it doesn't think it has enough memory. I reset my Virtual Memory and the game works fine.
To fix, try this
Right-click on My Computer icon, and select Properties.
Click on the Advanced tab,
then select the Settings button within the Performance section.
In the Performance Options window, click on the Advanced tab, and then select the Change button in the Virtual Memory section.
Click the Custom size button...
Change the Initial size (MB) setting to 4000
Change the Maximum size (MB) setting to 4000
Select SET to accept the change, which will close the Virtual Memory window. Select OK to close the Performance Options window. And select OK to exit the System Properties window. Oh, and don't forget to restart your computer. I hope this helps.

virtual memory


The topic of Virtual Memory can be confusing for some folks, but I'll try to explain it as best I can (starting with the basics).
RAM, or, "Random Access Memory", exists in every computer. RAM are actually pieces of hardware (chips) and are used to store temporary data. The temporary data is then used for computation by the CPU (Central Processing Unit) at a later time.
So, for example: when you double click to view a movie file on your computer, it is first loaded into RAM (a chunk at a time), then moved to the CPU (Central Processing Unit) where it is processed and decoded, and eventually output to the screen and sound card. And voila, you have your movie.
RAM is also known as "Primary Memory". Comparatively, Virtual Memory (also known as Secondary Memory or Page Memory) is used in place of Primary Memory, but only if there is no Primary Memory available at the time.
Since Virtual Memory is stored on the hard drive, it is significantly slower than RAM; therefore, virtual memory usage should be avoided whenever possible. To compare: hard drive speeds are measured in Milliseconds (MS) where as RAM speeds are measured in Nanoseconds (NS). Generally speaking, the more RAM a computer has, the faster, or "more optimized" it is -- especially when switching between tasks.
If you are constantly getting the message that your system needs to increase Virtual Memory settings and you're not overworking the PC, I would suspect a memory leak. This is, of course, assuming that you haven't played with your virtual memory settings in Windows (it's best to leave it alone or restore to default).


FIX
look in Control Panel: System, Advanced, Performance, Settings, Advanced, Virtual Memory. I believe it's in a similar location in other versions of Windows.

SONY PCG-V505DX make it run faster


put more ram in the laptop is the most economical solution at the moment, as it is so cheap.
your laptop can have 2 gig in total
other solutions that cost nothing
  • remove all unwanted software off the hard drive.( to make room for virtual memory)
  • empty recycle bin
  • run anti spy-ware software
  • defrag the hard drive
  • set virtual memory to 2 times physical ram
  • set performance settings to "adjust for best performance",go to device manager/advanced tab to do this
  • go to start/run ,type "msconfig" go to start up tab and deselect any software not needed at boot up,
  • leave anti virus,anti spy ware,and any firewall selected.
  • when you reboot a box will open saying you have been in making changes ,put a tick in the box at top right so it does not show again.

hope this helps you
please rate my efforts if worthy
good luck
