Can you tell me if it would be worth my while upgrading the RAM on my
machine? I have 512 RAM at the moment, Win XP, Inspiron 510m. I mostly use my
system for browsing the net and chatting on-line. Sometimes web pages take a
long time to open or video chat freezes. Would extra RAM help this?
Itâs impossible to say whether additional RAM would help the specific
symptoms youâre experiencing. It could, but there are probably hundreds of
other possible explanations for those symptoms as well that donât involve the
amount of RAM on your system.
So letâs look at what some of the more likely problems are, and whether more
RAM might be something to try.

Iâve long held that adding RAM to your system is one of the cheapest and
quickest ways to improve your systemâs performance. RAM prices have dropped so
dramatically in recent years that even if we donât think itâll help, itâs high
on my list to try anyway, just because.
512 megabytes of RAM could be enough for a fine Windows XP system,
but in all honesty, it depends on your specific system. If you have lots of
things getting loaded at start up, if you like to run lots of programs at the same
time, if you run few programs that like to use lots of memory, 512 megabytes
can actually be a limiting factor pretty quickly. Naturally there are two
approaches: reduce the number of programs running or the memory that they might
use if you can, or add more RAM.
low on RAM, keep an eye on your disk activity light.â
How do you see whatâs running and how much memory is being used? Thatâs
easy: you can do it with Task Manager, or my preferred utility Process Explorer. Once you run Process
Explorer youâll see a complete list of the programs running on your machine.
Click on the Working Set column header and see whoâs using the
most of your computerâs RAM. In Process Explorer you can also click on the
Virtual Size column header to see whoâs using the most total
virtual memory (both in RAM, and swapped out to disk).
I actually advocate both cleaning up running programs and having lots of
RAM. I hate having programs running that I donât need, even if only on
principal. And as I mentioned above, having more RAM doesnât hurt.
âą
Now, about those symptoms of yoursâŠ
Slow loading web pages are extremely difficult to diagnose. Theyâre more
often associated with slow internet connections, or other traffic eating up
your bandwidth. Make sure youâre not trying to do a bunch of things that use
your internet connection at the same time.
Occasionally browser speed will be affected by disk speed as it manages your
internet cache and history. Also, realize that the first time you visit a web
page it may often be slower than subsequent visits. The first time the browser
must download everything, but on subsequent visits your browser may be
able to avoid downloading some of the page contents by simply using the items
it already has in its cache.
Browser performance can also be affected by your machines processor
utilization. Independent of memory, if another program is performing
calculation-intensive work while youâre browsing, it can impact everything,
including how quickly your browser downloads, draws, and reacts to your user
input.
And yes, it could be memory. Again, depending on the configuration of your
specific system and what you happen to have running at the same time, RAM could
be an issue, and more RAM could help.
Video chat freezes are even more difficult to diagnose.
If itâs just the video chat application thatâs freezing, I actually tend to
blame either the application itself (try a different video application or
service), or the speed of your internet connection. Video can use a
lot of bandwidth, and some applications donât handle it well when
thereâs not enough bandwidth to deliver the video in a timely fashion.
Iâd also look at video drivers â specifically making sure that the drivers
for your video card are up to date. Some cards are better than others, and more
importantly, drivers occasionally have problems that can manifest in this way.
This is particularly true if itâs your machine that crashes or freezes
and not just the video or video application.
And yes, it could be memory. Just like slow loading pages, depending on the
configuration of your specific system and what you happen to have running at
the same time, RAM could be an issue, and more RAM could help.
In most situations where you suspect you are running low on RAM, keep an eye
on your disk activity light. If youâre not explicitly doing something on disk
yourself, and that light is flickering a lot, or even on solid, then thereâs a
good chance that youâve used up all available RAM and the system is using
disk-based virtual memory.
And lastly, more RAM may not help, there are just too many possibilities to
know for sure.
But more RAM wonât hurt either.
Some machines donât have dedicated memory for the video function â they âborrowâ memory from the main RAM for video. This can reduce the amount of memory available for your applications; itâs also much slower than using a video card with dedicated memory. Adding a dedicated video card to my daughterâs machine made quite a difference in the video and application speed. However, as Leo demonstrated in his answers, there are many variables at play and a little investigation may be necessary to discover the best solution.
There are many additional techniques for getting a feel of where the bottleneck is.
For example open task manager and watch its meters:
* is the CPU peaking out?
* is the network bandwidth maxing out the ISPâs max?
* what does it say about the âcommit chargeâ, how does it compare to the âphysical memoryâ?
Also, watch the âdisk lightâ on the box, is it busy? If so, then you might also need more ram (to serve as a disk cache &/or avoid paging/swaping).
Make sure that the browserâs cache size is large enough to avoid network downloads of content from sites you visit often, and that is willing to make use of that cache too (but it should validate its content on âevery visitâ ;-).
Older notebooks may not accept more than 512MB of ram, but most newer systems likely will (the one in question takes up to 2GB), and it will help in pretty much all situations that are not CPU or network limited.
Oh, and if you do upgrade the ram size, only use the proper memory for your system⊠and memory from a good supplier (Iâve seen lots of PCs that became unstable after putting bad memory in them, easilly discovered by a memory testing program ;-).
Hey there can u answer this, give two situations where memory is more useful when it is used as ram disk than using it as a disk cache

i would think that 512 is on the low side for running xp. 1gig as a minimum is what xp likes has been my experience
I have often spoken and heard the following pharse: âThereâs no such thing as a âDumbâ or âStupidâ or question.â However the following question may be borderline in being dumb.
How do I determine what I need, or what is needed, in all the things running on my computer? I know I should have Security systems running and I like Automatic updates.
So what else is necesary. What happens if I disable all except the two mentioned?

Hi
my problem is choppy streaming,,
I have an older computer with minimal amount of ram,,,
I watch a lot of u tube instructional vids(I love it ,,you can learn how to do anything,,except this)
it used to run pretty good before,,,Ive installedâadvanced careâ and ânortonâ and constantly run them,,,,
will or maybe adding ram help at all,,,
and,,any other suggestions?
I,ve turned off my hardware acceleration and adjusted preformance setting already,,
Thank you Very Much
@Frank
Hereâs an article fromAsk Leo which gives a workaround to the problem of choppy streaming.
