Desktop RAM discrepancy

Hey guys and gals

The sticker on the front of my computer says 1024mb DDR2 Ram, but system page says only 896mb. Where's the other 128mb. I've searched other people's threads on this issue in the past, and never found a solid answer. Is this like hard drives and mp3 players where the stated capacity is always a little more than what's actually available?

Also my motherboard has 4 ram slots, 2 are used I want to get two more. Are all ddr2 chips the interchangable? I see there's different mhtz available, how do I know which ones to get?

Thanks in advance....Kew

You have 1024MB RAM ... suspect what's mssing is

In reply to: Desktop RAM discrepancy

the RAM dedicated to your integrated video. That's pretty common for system with built or integrated video.

Video RAM

In reply to: Desktop RAM discrepancy

This will be because the built-in video hardware will steal some system RAM to use for video RAM. It's quite a common practice.

Goto or, in their memory advisor type in what they ask and they will tell you what kind of RAM you need.

another good source of RAM

In reply to: Re: RAM

Two excellent sites for anyone interested in finding out about possible addition RAM are:

Belarc Advisor - It runs an internal audit on your entire system (you can save the file) listing your compter profile. Info includes OS, System build serial #, Motherboard, Processor, drives, memeory modules (what is in each slot, and how many are used), hardware, software with version# and "KEYS". Plus lists all installed HOT FIXES.

Memory4All - you can either do it manually, or have their auditor scan your computer. It will tell you the maximum amount of RAM for your system, and the number of slots. (Use Belarc to known how many are vacant if you have not looed inside). It lists RAM modules and states their prices. (Fully guaranteed compatibility)

Why only 1 gb upgrade?

In reply to: another good source of RAM

Thanks for the responses.

Correction: Looking inside my my desktop, I only have 2 ram slots 1 used, 1 free.

I went to and took their scan. It said my system can max out at 2 gig by adding a second 1 gb ram board. Reading all the other info, they said a 32 bit system can handle 3 gig of ram, so why can't I get the 2 gb board they have. That would be the 1 gb I already have and the second 2 gb chip would add up to 3 gb. They also said my computer doesn't require matching chips. so why would the scan limit me to 2 gb?

The choice of memory sticks is determined by

In reply to: Why only 1 gb upgrade?

The machine's design, chipset and more. Crucial and others are pretty good at offering what will work and if you go over what they suggest, most of the time you find the machine does not report the full memory installed.

Since you omitted the machine details there is not much more to tell.

Depends on the machine but since you didn't give us

That's your clue.

In reply to: You're stuck at 2GB RAM

"Chipset : ATI Radeon? Xpress 200"

I remember that chipset and it was limited in this area due to bios and board connections. This is not to offer the full explanation but that's it.

Systems with built-in or integrated video (chips)

In reply to: Specs

on the motherboard usually have no RAM for video. For the integrated video to work, the system BIOS is used to set aside some SYSTEM RAM your case 128MBs for use as VIDEO RAM. If you installed a discrete video card... you could eliminate the 128MB SYSTEM RAM allocation for use as video RAM and you'd have use of the entire 1024MB (or perhaps 2048MBs) for system use.

That's why it's important to get sufficient RAM to run the system properly especially where the systems have built-in or integrated video and cut into the available RAM to function. As it stands right now, 12.5% of your SYSTEM RAM (1024MB) is being allocated and used as video RAM.

Let us know how the upgrade turns out.
