My system does not support dual channel memory?

Question

Hello   Can anyone help me.   My laptop has started running very slow and I've noticed some graphics are no longer showing. I think i need more RAM.   My laptop came with one gig. I think i need 2 now (my limit).   I went to a website (crucial.com) that has a scanner that tells them all about my laptop.   And this is where i need help - the scanner said 'my computer does not support dual channel memory'.   I don't understand. My laptop comes with dual channel memory.   My Laptop: Inspiron 1501, VISTA Premium (32 BIT), AMD Turion 64x2 TL-50 1.6 FSB 533MHz, RAM 1GB DDR2 533MHz, HDD 80GB, ATI x1150 256MB   nb. Integrated graphics are rubbish I know. nnb. I should have spent a little more and bought the Inspiron 1600 with more RAM and an actual graphics card.   Nevermind. You live and learn.

Hi Chris   I thought it does. Don't know why the website says not (and yet recommends it).   Thanks.

Hi

The Inspiron 1501 does not run in dual channel mode Dell was selling them

awhile back with just one stick of 512 mb of ram and

Vista 32 bit Home Basic i thought that was not right and did some checking

and it does not run in dual channel mode.

If you look at the manual it has nothing about DCM.

See Yea

Edit here is the link to the manual.

I think it is a AMD thing verses intel.

Hi C3PO5   Thanks for your help.   Still worth upgrading my RAM to 2MB I guess.   Not a lot else I can do.

What you want is 2gb 667 mhz DDR2. I had a 1501 and it ran great. I didn't like the bios for the 1501 so I sold mine.

I now have E1505 and want to get the new 1520 with that slick nvidea 8600 video. Both are Core2 Duo.

2gb 667 mhz 5400 DD2

I do not think it is possible to run any PC with shared memory in dual channel mode, even if the system supports it.    Dual channel the memory modules have to be installed in matched pairs of the same size. When the Video takes some memory they are no longer matched pairs.   Anyway Dual channel memory mode is not available on the Inspiron 1501. It runs well on 2 GB anyway or should I say 1.918 GB as it does share memory with the Video... :smileywink:   pcgeek11

Shared memory has nothing to do with dual-channel, it's just that particular system doesn't support it. I run 3GB DDR2 PC5300 @ 667Mhz in dual-channel mode. That's what cpuz and my bios says.

Heres how my 3GB is allocated

total system memory: 3GB

total available graphics memory: 1535mb

dedicated graphics memory: 256mb

dedicated system memory: 0

shared system memory: 1279mb

you are correct about the matched pairs for dual-channel
