Does dv6-6000 ( i7 sandy bridge) supports 16gb of ram?

[justinkw1]

Sandy Bridge notebooks should be able to support 16 GB of RAM (2 x 8 GB), regardless of the BIOS version being used.

If my dv6-2000 with Core i7-720QM Nehalem processor supports it, I'm pretty sure the newer i7-based laptops do too!

The problem is that with the latest bios the screen brightness buttons don't work under linux, if I can't fix that I'll downgrade to the f.06 bios and hope the pc will recognize my 16gb when I put them in.

I don't expact to test it anytime soon ( maybe in a month ) , but when I'll, I'll post the outcome here ( unless someone will try it before me ).

That's not a problem, just put " acpi_backlight=vendor " in your grub config and the brightness buttons will work again. [This was already covered by a thread in this board]

Be careful with what you say ... only the quad cores support 16GB, [the i7 dual cores with HT are still limited to 8GB according to Intel].

Tried it, it didn't work.

I've solved this by putting this under /etc/acpi/default.sh ( the default event if there is nothing specific under /etc/acpi/events )

BRIGHTNESS_FILE="/sys/class/backlight/intel_backlight/brightness"
case "$3" in
    00000086)

        	brightness=`cat $BRIGHTNESS_FILE`
        	brightness=`expr $brightness + 400`
        	echo $brightness > $BRIGHTNESS_FILE
	;;

    00000087)
        brightness=`cat $BRIGHTNESS_FILE`
        brightness=`expr $brightness - 400`
        echo $brightness > $BRIGHTNESS_FILE

esac

00000086/00000087 is what generated when I press fn+f{2,3} (found it using acpi_listen )

I respectfully disagree - Sandy Bridge dual core notebooks should support 16 GB of RAM as well. Take a look at the Intel ARK pages below for examples...check the row indicating Max Memory Size.

Core i7-2620M:
Intel® Core? i7-2620M Processor (4M Cache, up to 3.40 GHz)

Core i5-2430M:
Intel® Core? i5-2430M Processor (3M Cache, up to 3.00 GHz)

Then check out these:

Core i7-2647M

Core i7-2629M

Core i7-2677M

Unless intel is playing fuzy with me, these i7 have 8GB limit.

Hmmm, the processors you linked to are the low power variants. (Max TDP: 17-25 W)

These processors don't actually fit in the dv6 / dv7 notebooks because they are a different type of socket (BGA1023), as opposed to the Socket PGA988 processors that are used.

ok, guess the core i7 got me confused.

But you had a standpoint that was certainly understandable - Intel's naming scheme is a little wonky at times and they usually don't depict the specific differences between processors. There are certainly better ways to name some of them.

What model dv6?

http://h10032.www1.hp.com/ctg/Manual/c02842252.pdf YES:16GB SandyB

http://h10032.www1.hp.com/ctg/Manual/c02657339.pdf Uhmmm (not SandyB)
