HP Pavilion dv7t Entertainment PC Memory Upgrade Question

Product name: HP Pavilion dv7t-2000 CTO Entertainment Notebook PC

PRODUCT # NB444AV

OSOriginally installed: Windows Vista 64-bit Home Premium

Currently installed OS: Windows 7 64-bit Home Premium

When I bought the laptop, HP included a "FREE upgrade to 4 GB DDR2 memory (2 Dimm) 2 GB DDR2 memory (2 Dimm) system system'. I don't check then. Now, when it is slow, I checked the memory installed by 'Start-> computer-> (right click)-> properties-> installed memory (RAM). It shows that 2 GB.

I'm baffled why it shows only 2 GB of RAM now, when HP was supposed to install 4 GB. In any case, I would like to upgrade memory now.  I have referred to as "HP Pavilion dv7 Entertainment PC. Maintenance and Service Guide "."  He describes the memory Module as:

Spare part number description
Memory 2048 MB (1-DIMM 667 MHz, PC2-6400),: 480382-001
Module memory 1024 MB (1-DIMM 667 MHz, PC2-6400),: 480381-001
Module of 512 MB memory (1-DIMM 667 MHz, PC2-6400),: 480380-001

My question: can I use a 4 GB Kit (2GBx2) DDR2 800 MHz (PC2-6400) SODIMM 200 pin notebook Modules memory in the crack avialable? Memory at 800 MHz won't be compatible with 667 MHZ memory?

I can't install module memory 2 x 4 GB to 8 GB? Will it be recognized by the card mother/BIOS/Windows?

Thank you for your expert advice.

You are the very welcome.

Here is the link to the service manual for your laptop.

http://h10032.www1.HP.com/CTG/manual/c01689926.PDF

Please see Chapter 4, page 54.

It seems to me that there are two memory slots (one almost on top of the other). Take a look at the illustration.

This is why the memory in Chapter 1 specifications indicate that you can install up to 8 GB of memory (2 x 4 GB).

You can install a single chip PC2-6400 4 GB and leave the one you have in there now.

It comes to the module memory 4 GB good cheaper brand I could find.

  • Pavilion dv6 entertainment pc: memory upgrade

    Can I upgrade the memory in my dv6 - 6047cl from 8 to 16 GB?

    Yes because it is an Intel processor:

    Manual

    p. 5

    Of course, the question is why? 16 gigs is overkill for most people who use never totally 8 gigs. The money could be better spent on an SSD. But yes you can upgrade to the modules of 2 x concert 8 or 16 GB of DDR3-1333 SO-DIMM memory.

    The manual tells how to make and references HP for the upgrade of memory.

  • HP Probook b 6450 memory upgrade question

    Hi all

    I seem to have a strange question seeks to upgrade the memory in a HP 6450 b probook (i5 - 480 m & ATI card). The laptop came with 2 GB of sps p/n 598856-002, which is ram 1333 mhz 1.5V with the manufacturer being ramaxel. I ordered and installed a few sticks of kingston 4 GB

    http://h30094.www3.HP.com/product/SKU/10473659/mfg_partno/KTH-X3BS/4G

    Mounted to them and all appeared to be as well as the operating system (win 7 32 bit pro) showed the recognized as 8 GB stick and 3 GB usable, the bios also reported 8 GB as well. However the moment that a 64 bit OS (Linux or Windows) is tempted to run just the laptop falls down or crashes

    I already tried this upgrade with two sticks of crucial memory but had exactly the same problem, so think about crucial memory was the question I put to the supplier and ordered the kingstons rather.

    I saw very similar question mentioned here:

    and

    http://superuser.com/questions/580512/HP-ProBook-6450b-not-booting-after-memory-upgrade

    My instinct suggests this notebook can be very picky about the memory chips, it may have to be a 4 GB key 16 chip versus chip 8 4 GB sticks.

    Thoughts and help on this would be greatly appreciated.

    Thank you

    You are the very welcome.

    Yes, I have never, ever install any module of memory in my notebooks from HP that does not 16 chips.

    All the chips I use - 2 gigs and up, have 16 chips (8 on each side).

    Never had a problem.

  • 9150 memory Upgrade - Question once again

    Good day to all,

    I have 2, Dimension 9150 who receive upgrades. The first machine was fine with OS WIN 7 / 32 PRO. Updated BIOS (A07), not installed the required software, no problem, everything no problem. RAID driver install also, no problem. Problem I have is the memory upgrade. Get machine 2 update, but not until this problem is resolved.

    Been revised post old topic of memory and still has not found an absolute remedy to my question. Machine (1 and 2) are 2 GB; 4 512 PC2-4200 (all locations showing on bios config).  I installed 4; 1 GB PC2-5300. Problem? Must not like system accepts 4 GB maximum and is also accepted speed Max.

    My problem is 2 GB in slot 1-2 (white) are good, no problems (boots to windows without error beeps). Check the BIOS and find sticks of memory are reading fix it. When I add the other 2 sticks of 3-4 (black), error on boot beeps and lights 1-3 lights telling me memory error.

    I recently updated a dimension 4700 and used memory not dell Komputer Bay. Could see all the modules and showed 3.76, so I bought the same memory for this machine. I know that in the past, Dell machines are "FINICKY" when it comes to memory.

    Is this the case? If so, Crucial memory has been discussed and I might add 2 (2 GB each)? That's what I was not able to see the answers. Part of the crucial says Yes, post only memory. The other Yes was that I could use sticks of 2 GB. Spec note 1 GB is max stick, per slot.

    I am at a loss, if you're looking for an idea on a direction.

    Yes, low density 2 rank INTEL chipset compatible ram works fine. The other way to say it isn't that 380 Precsion ecc ram works fine.   The GX620 has the same problem where we will see more ram by the bios but total ram is limited to 4 concerts by the chipset.  Upgrade to a precision 380 allows a full 8 gigabytes of ram.

    You could put 4 x 2 gig and he would show even in the bios but the ram would not be usable and the machine does not start with 64 bit OS.

    Hello, I have a HP 21 2014 all in one computer. He now has 4 GB Ram memory and an AMD processor. I was wondering how it would be possible to increase the Ram up to 8 GB. Is there a certain number of model or brand of Ram do I need to buy? I looked a few things on Frys Electronics, but obviously I'm naïve. I really want to upgrade memory because I have some games which really lag on this computer, even if it is new, and I know it takes more may work properly. I wanted to see if someone can point me in the right direction. Price is not really a problem, I just want to know what would be a better job for this specfic HP model. Thank you!

  • Tecra M7 memory upgrade question

    Hello everyone, I would like to upgrade the RAM on my Tecra M7, which came with 1 GB and is supposed to get a free site available. Since the system's maximum memory is 4 GB, I guess you can use up to 2GB stick into each slot.

    My question is: can I have a 1 + 2 GB configuration (with / 3GB in total) or modules should be combined for better performance (1 + 1 GB) DDR2? I read somewhere something memory dual channel working only with identical memory modules, but I'm not an expert so I don't know?

    Any idea anyone?
    RADO

    Of course, you can mix the sizes of memory. It s nothing unusual!
    You can use different memory module sizes, but you should be 100% sure that both modules supports the same specifications as DDR2 533 MHz (PC2-4200)

  • Satellite A105-S4064: memory upgrade Questions

    Hello

    I plan on upgrading the ram in my Toshiba A105-S4064 (preinstalled with 512 MB). I wanted to discover a few questions, if I could.

    First of all, what RAM would be compatible to install in housing, no?

    Second, the size of the new RAM should be the same as the RAM that is already installed (in other words, 512 MB)?

    In addition, only adding the new RAM to a laptop invalid warranty Toshiba?

    Thank you very much for your help!

    Hello

    I see that you have several questions about upgrading memory on your A105
    OK I'll try to make the best, I hope ;)

    Firstly you can upgrade the memory and the warranty still valid
    Upgrading memory hasn t any bad influence on the validity of the guarantee

    Second, you can mix the sizes of memory. … for example, you can use 256 + 512 or 512 + 1024 MB, etc.
    This is possible because you can upgrade it to 4 GB max

    And now finally something you kind of compatible modules it looks like you could use a DDR2 PC2-4200 533 MHz modules

    I hope this info will help you :)

  • Equium A60-692: memory upgrade question

    Hi, I want to improve my memory. I wanted to add a memory of 1 GB on the extra slot but I wanted to be sure that I'm looking for, I don't know much about it and I want to ensure I have buy one that is compatible with everything. If someone knows something about this answer please.
    Thank you

    Hello

    Well, you're first time here in the forum ;) Welcome!

    Now to your question. AFAIK the Equium A60-692 was delivered with an internal memory of 256 MB. This module cannot be deleted.
    Additional memory location is available and you can upgrade the memory for max 1280MB (256 MB + 1024 MB) in this case, you can use a 1 024 MB module.

    You use PC2100 DDR - RAM memory modules.
    Also, I found one that you can use without any problems. The reference is: 1024Mo PC2700 (PA3313U-1M1G)

  • Pavilion Sleekbook 15-B142DX memory upgrade

    Hello, I recently bought and installed an upgrade of DDR3 4 GB memory for my Pavilion Sleekbook 15-B142DX. It is PNY PC3-10666, chip of 4GB which says it's compatible with 1333 MHz and 1066 MHz I booted the laptop after the installation of the new chip, but reports still 4 GB of physical memory, msinfo and other online tests. Yet once, I opened the computer suspect that the chip was not fully connected. While there, I pass the tasks of the 1st round and the new stick. The computer registers yet only 4 GB of physical memory. Did I buy an incompatible chip or it's probably another problem?

    Thanks in advance.

    Hi Paul,.

    I received a HP technical support solution. The chipset you recommended works very well (thanks again). Here is the solution, in case anyone has the same problem with this model:

    (1) I removed the new chipset

    (2) I started the computer and went to menu BIOS setup > Boot Options > Secure Boot (those may not be the exact names)

    (3) switched start safe for people with reduced mobility.

    (4) reinstalled the new chipset

    (5) on the machine

    (6) checked to make sure that the computer record 8 GB

    (7) turned Secure Boot on

    Ensure that the computer has saved 8 GB 8) Made

  • HP Pavilion g6-2249wm Notebook: RAM upgrade question

    When I ordered my laptop a few years, there is, it came with 4 GB of RAM standard, but you could spend up to a maximum of 8 GB to 6 GB. I bought it with 6 GB. I want to move to 8 GB, and I know there are 2 RAM slots in the laptop. My question is, did they use a 6 GB stick in one of the slots or the fact that they use a 4 gb one and one 2g in the other? Im hoping to get a response, so I don't have to open it up and look for myself. I don't know if I should order a 2 GB or 4 GB a stick to get up to 8 GB.  That being said, someone knows if HP would be put in a 6 GB stick or run a 4 GB and 2 GB as a whole? IM assuming they put in a single 6 GB and I just need to buy a upgrade 2bg. Thank you

    Moreover, it would go better if I just replaced it and got a bar of 8 GB of RAM?

    I can tell without looking or read whatever it is, that it isn't just a 6 gig of memory because those who are not 'a thing' as the kids say. You can actually get a software called Belarc Advisor to do the dirty work and interrogate the locations of memory and tell you what is in it or them.

    http://www.Belarc.com/free_download.html

    But since there is no 6 concert sticks; only 2, 4 and 8, we know that you have a 2 gig and a 4 GB and you can mix the 2 and add a 4.

    The laptop will not support 8 modules of concert and it will work better with 2 of the same size due to something called mode memory dual channel which is only used when you have two identical modules. So yes, you need to duplicate the existing 4 GB module for a total of 8 and you will see a modest but noticeable improvement in speed.

    I'm looking for 1 oiece 128 MB of memory (MAX)? for my 720cdt. Can someone help me as to a place that I can get this or does anyone have good used sweater, that they no longer need.
    Just tell me what you need.

    Thank you

    Garth

    Wow, that's a really an oldie.
    To my knowledge it s about 10 years.
    What do you what to do on this old notebook?

    In any case, I remember that the slot of memory could be at the bottom of the unit.
    Am I wrong? In addition, you can use module max memory 128 MB and the memory can be upgraded to 144 MB. Why? Because as far as I know that this unit should have internal 16 MB memory and it cannot be removed.

    I searched a bit on the net and found information that this module memory must be compatible:
    PA2046U 128 MB

    These modules you should be able to order the Toshiba service partner in your country.
