HP HDX18-1180ed MaximumGB of RAM

What is the maximum speed of the 4GB memory modules that can be
installed in this laptop?

1066 or 1333 MHZ

That machine was actually harder to trace down than I expected.

I couldn't find the machine listed on Crucial.com
(But since you own your laptop, you can use the Crucial "system scanner"
feature, and see if they have the information or not. The system scanner
may be more accurate.)

On the Kingston site, they were offering only 800MHz.

This site says the processor is P8600.

http://nl.hardware.info/productinfo/...:specificaties

In the block diagram here, that design has the memory controller on the
chipset. So you need to know more about the "MCH" chip, to know the limits.

http://ark.intel.com/Product.aspx?id...c+1066+MHz+FSB)

The chipset could be PM45. But even that information doesn't narrow it
down, because the PM45 supports DDR3 and DDR2 (just not at the same
time - they have to select one type when designing the computer).

Page 13 here shows DDR2(667/800) or DDR3(1066/800) as options for PM45 design.
So that narrows down the speed a bit.

OK, I found this brochure from HP.

HP HDX X18-1180ED Premium Notebook PC
http://h20195.www2.hp.com/V2/GetPDF.aspx/c01646468.pdf

Geheugen 4096 MB (2 x 2048 MB)
Ondersteunt tot 8 GB DDR3-geheugen

So it is using DDR3 memory. The Kingston product offered for the machine
is DDR2. Very confusing! I still cannot be positive of the type of memory.

I suggest you run CPUZ, and verify the hardware information from
inside the computer.

http://www.cpuid.com/softwares/cpu-z.html

CPUZ will show you a memory tab window similar to this, and then
you can determine if it is DDR2 type or DDR3 type.

http://www.cpuid.com/medias/images/e...es-cpuz-04.jpg

In terms of performance, the processor FSB could be running at FSB1066.
That is 1066*8 = 8500 MB/sec. Two modules run in dual channel mode,
whether DDR2-800 or DDR3-800, would be 2*6400MB/sec or 12800MB/sec, so even
with relatively slow-sounding memory type, the memory subsystem is
still faster than the FSB. The FSB is the bottleneck.

You can generally use a faster memory type in a slower computer, as
the module speed can be operated over a range of values. But there
wouldn't be any advantage to you, to using fast modules.

If this was my computer, the next step would be using CPUZ. Since
the HP brochure doesn't agree with the Kingston page, you need to
confirm the memory type (DDR2 or DDR3) first. If the machine was
using DDR3, the fastest DDR3 for PM45 is DDR3-1066.

Tanx,

Yes it is using DDR3, currently running 2*2GB 1066 MHZ DDR3.
So upgrading to 2 * 4GB on 1066 is possible.

However will it run with 2 * 4GB 1330 MHz?

That is a function of the chipset.

Is the chipset PM45 ?

If it is PM45, you can read about it here. The block diagram
says DDR3-1066 is the fastest speed PM45 can run (page 13).

http://www.intel.com/Assets/PDF/datasheet/320122.pdf

If you install DDR3-1333, and the chipset cannot run
that fast, then it will run the memory at DDR3-1066 instead.

Paul

Paul,

Yes, it is.

Paul,

Heaps of information. Tanx for that, again. I am running Windows 7 64
bit. So that is not the problem.

So it is currently running DDR3-1066 and according to the Intel datasheet,
that is as fast as PM45 goes (stock settings). Laptops don't generally
have provisions for overclocking, because that would affect battery
life.

Your memory subsystem is already pretty good. How will this change
from 4GB @ DDR3-1066 to 8GB @ DDR3-1066 pay off ? Do you use a lot
of Virtual Machines ? Are you using a RAM Disk ? There are people
who do simulations who need lots of RAM, but for a lot of other things,
you might not be able to tell the difference when the new RAM is installed.

http://memory.dataram.com/products-a...ftware/ramdisk

When I changed my current computer from 2GB to 4GB, the main benefit
was I was able to run three virtual machines at the same time. For most
other operations of the computer, the extra RAM made no difference.
