I have a HP DV9235nr laptop running Vista Premium. It is running 2x1gb chips. The hardware specs says the max memory is 2 gb.
Has anyone installed more memory than what the hardware says is the max? I might want to throw in 2x2gb chips.

If they manual says no then its no unless than have bios updates. Try go on Hp's site and look for bios update regarding the information supporting 4GB RAM.

That's what confused me. I checked their recent bios update and it addresses an issue when have 4 gig installed:

Release Date: 2007-05-28 Version: F.25

Description

This package contains the WinFlash utility and a BIOS image for the supported notebook models and operating systems. The WinFlash utility is used to locally flash the System BIOS (ROM) on notebooks operating in a Microsoft Windows orMicrosoft Windows Vista Operating System environment.

PURPOSE: Recommended



Fixes

Fixes issue where a "blue screen" error is generated if the notebook has two 2-GB memory modules installed.



Enhancements

Modifies thermal control method to improve system stability.


So, I'm thinkin I might be able to get away with it.

yup i went through those :)

See the "HP Pavilion dv9000 Notebook..." thing :)

I say just go for it
I think I will since the last bios update talks about addressing the issue when 2 2gb modules are installed.

so i installed my 4gb memory on my HP DV9235nr laptop.
The bios sees all 4096 of memory but Vista Premium64 only sees 3070. I keep reading everywhere that vista 64 should see all 4gb. What's goin on? I tried lookin at MS support but found nothing

Nothing is wrong -- your hardware limits the amount of memory usable by the OS. In order to use more than 3GB+ of RAM in Windows, you need:
1) A 64-bit version of Windows (you have this)
2) A 64-bit CPU (you have this)
3) A motherboard chipset that supports 8GB or more of RAM (your notebook probably doesn't have this).
4) A BIOS with a memory remapping option (your notebook probably doesn't have this).

My vista premium is 64bit but it sounds like the hardware may be the limiting factor. I rolled the dice on it since I saw a person with a similar model laptop get away with installing 4gb and windows detecting all 4gb.

I'm wondering if this ever got resolved, and how? I have upgraded the BIOS to F.27, the latest HP Intel BIOS. As is reported above, the BIOS reports seeing 4096MB, but Windows is only seeing 3070MB. I have a DV9330CA running Windows Ultimate 64-bit. HP is selling pre-configured 64-bit machines with 4GB now, so there should be a way to get this right. The Chipset is an Intel 945GM which supports up to 4GB of RAM per Intel, yet I notice the above post mentions 8GB as a necessity - why? Does this mean a DV9000 series with an Intel 965 chipset supporting 8GB of RAM will display a full 4GB in Vista, but a 945 series will not? Help? Thanks.
