im using a similar Dell ,a GX620 with the same CPU ,mind you it aint super fast ,and neither is yours ,but it works quite well ,the hyperthreading helps and needs to be set in the bios if it isn't already .i have a 320 gig sata 7200 rpm drive
I have 4 memory slots and at present have 3x1 gig ,with one empty slot .
I'm using ddr2 pc6400 ram ,[likely running at a lower speed but the price was right ]1 samsung and 2 kingston ,running win7

thanks for your fast reply. heres the link i got from the program: http://speccy.piriform.com/results/gTlG1td13fMOLxWXJj0qKBU
i know i wont end up with a high end computer but i got this one really cheap and the gfx card wasnt very expensive either. i just like to get the best out of that mashine. i defenetly have two slots (i checked it today) and yeah it works quite well,for my needs ;)

It will work great im sure ,it has the same cpu as mine ,and mine works great for what i use it for too. i would try to at leat add 2x1 gig sticks of ram ,removing and replacing both of the 512's ,i was just making fun of the description on the site where you bought it .[A top end Dell model, featuring a super fast
2.8 Ghz Pentium 4 Processor ] I paid 32.00 cdn for mine ,it had no ram or harddrive or cdrom ,but was well worth 32$.i added 3x1 gig ram[45.00 each ] and a 320gig hhd[60.00] and external dvd drive [45.00]enough about mine .lol, mine

what version of window are you running
this is the ram in yours from the speecy program .
Size: 512 MBytesManufacturer:
KingstonMax Bandwidth:
PC2-4300 (266 MHz]

one thing to watch for is that its pc2 4300 non ecc type ,and not ecc type

i would add 2x1 sticks, like one shown here .or if you can afford it go for 2x2gig if you want for best results

haha yes the description is funny,and i deleted half of it already lol. I bought mine here in ireland and paid 100 EUR for it. the OS is win xp profesional sp 2. addionaly i had to buy an external dvd drive (40EUR)and a ext. harddrive 500gb for fourty quit as well. plus the gfx card 35Eur. i think generaly computerstuff is more expensive of here. if i can scratch the pounds together i go for a 2*2gb extensions.
i think i gonna go with them:

thanks a lot for your efford mate

Windows XP can handle a maximum of 3gb of ram! This includes the ram on the motherboard combined with the ram on the graphics card! If you exceed the 3gb limit then the computer will be slower!

If you decide to upgrade to windows7 at any point then you can use as much ram as your motherboard an take combined with any high end graphics card if you want to!

nope , the ram it that link is for a laptop ,not a desktop computer[sodim ram is laptop ram ]

so if i get you right the maximum ram for my OS is 3gb? the gfx card already takes 512mb,so it leaves 1-1/2 gb. is that right? by the way..is there a difference with win xp 32 bit and 64bit? id like to stick with xp since it is (in my opinion) a well working OS.could i enhance the ram it takes by upgrading to 64bit? and if yeah , how do ido it?
excuse my english and ignorance about hardware stuff.

the gfx card already takes 512mb,so it leaves 1-1/2 gb. is that right?

Correct, except it'd be 2.5gig of ram rather than 1.5!

XP 64bit will only go on your system if you have a 64bit CPU. Getting drivers for XP 64bit is an absolute nightmare too! I wouldn't recommend XP 64bit because of the driver issues and also the fact that most software wont work with it either!

yeah, got that mathmatical mistake :)
iam happy with an 2gb ram extension, could you post a name for those chips please? its not cause iam to lazy to have a look myself, but its so much stuff,numbers,and things that i most likely end up getting it completly wrong. thank ye's for your time.
instead of "happy christmas" anarchy and peace.

Not sure what you mean by "post a name for those chips please?". Do you want make, size, type, or speed?

well..happy new year first. I mean themake for a 1gb ram chip that would suit my computer specs.

Go to www.crucial.com and use their scanner to find out what ram you have and what your system can take.

For best results DO NOT MIX DIFFERENT RAM SPEEDS. I have come across many many computers with serious instabilities caused by mismatched ramand, in a few cases, damage to motherboards!

i tried crucial and it gives me different specs then the program speccy did. and it doesnt give a brand name for those chips either, just a list of chips i can buy from them. i live in europe and dont wanna order stuff from the states (to safe the shipping costs) thanks anyway ill go bring my pc to a computer guy let him fix the problem.

Crucial is the best for RAM updates.
Otherwise go to the manufacturers website to download the manual for your motherboard.
