I want to buy RAM for my pc...

August 22, 2010 at 14:47:22
Specs: Windows XP
I've looked a little bit and I'm pretty lost. Why do they make things this much complicated?? Anyway, here is what I have:
OCZ Platinum XTC REV.2 PC2-6400 2GB 2X1GB DDR2-800 CL4-4-4-15 240PIN DIMM Dual Channel Memory Kit
Is the timing only the CL4 or the whole sequence?

Can someone suggest me some equivalent please? Thanks verryyyyy much!!

Most dual channel needs to be matched in pairs.

What are you trying to do? Add in more ram or replace one stick?

Why did it take me over a year to phone in a problem to ATT?

Yep add more RAM. I have 2x1gb like above, I would like to add either 1x2gb or 2x1gb (or even 2x2gb for the right price)

The timing numbers don't have to be the same, but the voltage spec for all the ram modules must be the same. Some ram modules don't use standard JEDEC voltages, especially PC6400 (a.k.a. PC2-6400) and up.

The voltage for the modules you have now is probably on a label on the ram - if not, look up the voltage on the OCZ site by using the part number on the module.

See response 5 in this for some info about ram compatibilty, and some places where you can find out what will work in your mboard for sure:
Correction to that:
Mushkin www.mushkin.com

The OCZ site has a ram configurator or similar too, but I know from previous experience it hasn't got as many system model or mboard model listings as most configurators do.

Once you know which module ID strings (part numbers) work in your mboard, you can get them from anywhere you like that has ram with those ID strings.

If you have brand name ram, it is usually easy to look up whether it's ID string (part number) is in a list of compatible modules found by using your mboard or brand name system model number.
If the ram is generic, that may be difficult or impossible.

If you add 2 more gigs of ram, you do realize that Windows xp will only see 3.5 or less. 2 gigs is fine for most applications. You could wait until you upgrade to Win7, but even then Win 7 32 bit will only see the same amount of ram as xp, unless you use the 64 bit version. It's your choice, but I think you would be wasting your money.

Thanks for that, but I still have no idea where to find a comparable RAM. It's 3 years old now, which is a lot in terms of informatics. I'll give it a shot for the ID model that you talk about, but even on www.ncix.com there's not a whole lot of choice that looks similar to mine.

As for the 32/x64 architecture, well thanks very much but I already knew that.

and how is it I cannot find the voltage for my current RAM??

"and how is it I cannot find the voltage for my current RAM??"

Did you try the OCZ website or is that too obvious?


BTW, it's pointless to install more than 3GB RAM when running XP 32-bit.

lol will you guys stop with the 32 vs x64 comparison? Where did I say I was running a 32-bit os?

Or was it too obvious? :)

You state Windows XP below your name in your first post.
If that's what you have on the computer, and if you don't have XP Pro 64 bit, most people have XP Home, XP Pro (32 bit) or XP MCE, and have a 32 bit operating system, it can't use more than 4gb, and when you install 4gb not all of it can be used and you're often better off installing a max 3gb rather than 4gb.

"As for the 32/x64 architecture,....."

All modern mboards and cpus have 64 bit architecture. Whether the operating system is 32 bit or 64 bit is a different matter.

I took a look - the www.ncix.com site does not show the ram voltage for most of the ram modules they sell, in the ad.
Kingston configurator only

Since you're looking on www.ncix.com , I assume you're in Canada. ncix has a physical store in B.C. .

Memory Express http:// www.memoryexpress.com
- physical stores in Calgary, Edmonton, Winnipeg
Kingston configurator only

physical stores in Ontario
Multiple brand configurator

Newegg is in the US, but that site allows you to order from Canada - the shipping charge is similar to when you order from a Canadian web site, not more.

You have not told us what make and model of brand name computer or mboard you have, or what cpu you have.
You may benefit from installing all faster ram. E.g. if you have a Phenom cpu, and if the mboard supports it, you can use PC2-8500 (1,066mhz) ram and see a significant performance improvement, even with the same amount of ram.

You don't necessarily need to buy ram from the web. If you live in or near a reasonably large enough place, local places that sell computer parts often have web sites - if you look in the yellow pages the url is often stated in their ad.

Thanks for the very detailed post tubesandwire.

I will go to a store near here. My motherboard is a asus p5k-3 wifi. Should I just buy faster ram and ditch the ones I have?

BTW, seems like it seems to be a big misunderstanding, I am using debian 64bit. So please stop telling me I can't use more than 4gb on a 32 bit system. I knew that for a long time!!

Thanks again :)

"My motherboard is a asus p5k-3 wifi."

Asus does not list any p5k-3 model.
They list P5K3xxxxx models, but those use DDR3 ram only.

Please provide the correct model number.

Where to find my model name ?

Which cpu is installed?
Your mboard model probably supports using PC2-8500 ram, but whether you can benefit from faster ram often depends on which cpu you're using.

E.g. Phenom cpus can make good use of PC2-8500 ram - many Athlon 64 X 2 cpus can't benefit from PC2-8500 ram - PC2-6400 specs are the max they can support.

"....I am using debian 64bit. So please stop telling me I can't use more than 4gb on a 32 bit system. "

We can only go by the info you provide in your specs in your first post near your user name, or in your posts. How are we supposed to know you're using a 64 bit operating system when you haven't specified that in your specs or mentioned that previously ?

That's my point, you guys implied that I was.

Nevermind I found some that works fine now. Thanks for the help though, appreciated

I think it's really important to max out your RAM on all of your computers. Good idea!

There are a bunch of places where you can buy new RAM, I would just stop by a store and ask one of the people there. Just make sure you go somewhere you trust. http://www.tracs.ca
