Max RAM suported on Inspiron 1420

by magic2me / November 3, 2009 7:09 PM PST

Can anyone advise what is the max RAM this dell Inspiron 1420 can support? I know I have been told the max RAM support with current Windows Vista (32-bit) is 4GB. But If I am to go for 64-bit Windows Vista or Windows 7 later, what would be the max ram the hardware can support?
I tried to ask Dell support center but they keep telling me it's not advisable to go 64-bit coz it's not tested, and there will be drivers concern.
I just need to know on the hardware end, what is the max ram it can support. 64-bit windows can support more than 4GB, but what would be the limit on the hardware end?
Appreciate if anyone can enlighten me.
Thank you.

The answer is exactly as it should be. They support 4GB so today the support is for that.

You can see if offers more than that.

Can I ask why many are going to add over 4GB? I saw little speed increases past 2GB with Vista and Windows 7 even in the 64 bit versions. Let's share this percent. Less than 1% speed up.

Hi! Bob,

Thanks for your response. Not that I needed to add more than 4GB soon, but to understand if my hardware has any limitation to go beyond that. I currently has 3GB ram on my Dell 1420, and frankly do not see much improvement over 2GB.

Reason is I know that 64-bit Windows Vista or Windows 7 can support more than 4GB, hence the question that come to mind would be is the hardware able to support more than 4GB too? Do you think the hardware would impose any limitation on the max RAM it can support? besides what the operating system can?

Thanks, that link was very informative.

So it seems it's quite clear that the max supported ram is 4GB. Unless I would go for 64-bit Windows later, otherwise I would be just be in very good shape for a long while with my 3GB currently.

Again, thanks for your guidance.

Sorry for the typographic error.

I'm on a new machine and still learning the new keyboard layout.

It came with Windows 7 Pro 64-bit and 4GB DDR3 RAM so all I can offer is it seems plenty. I'll share why I changed. It was Vista. My new job is writing Windows Mobile apps and Vista was like a drag chute in what may seem small ways but they all add up to a drag effect.

From my trials with 7 beta, 7 RC and this new machine, I would not upgrade a 3GB machine. I would however opt for 64 bit if it can be done for a price. Why? Most of the Windows 7 free upgrades are for the 32 bit version. Why this is so is that makers are not prepared for owners to scream at them about what it takes to jump from 32 to 64 bit during the install. More about that in the Cnet Windows 7 forum.

Again, I'd get the 64 bit Windows 7 but not bump the ram.

to 64-bit Windows 7

Yes, I am considering upgrading Vista to Windows 7. That's the reason why I started checking on the memory requirement too.
But I couldn't understand so much why is it better to for the 64-bit Windows 7, rather than 32-bit?
I am of the understanding that if I have the need to make use of more memory (like more than 4GB) then only I go for the 64-bit.
Would you help me to understand it more about moving from 32-bit Vista to 64-bit Windows 7?
Thank you.

You find that discussion is done many times in the Computer Help, Windows 7 and other forums. I can't see what more I could add here.

Don't buy if they won't answer.

If the seller and maker won't tell you it's compatible, then it does not matter what I say here. But what I often write is to check the page as they will backup their compatibility claims.
