EliteBook 8540w ram upgrade
Good day my Pro friends! Here me again. I am in a quandry that needs expert advice:
I have an Elitebook 8540, w / 720qm CPU Intel. I run Win.7Pro. 64 bit. now, according to the maintenance manual, the ram for this unit should be a maximum of 16 GB, (I know) and uses 10600 or 1333 MHz modules. Now, every time I check with one of the manufacturers of memory, on the compatibility updates, they list, (or if I use their scan) I can go to modules 12800 - 1600 MHz. At the present time, I have 6 GB of 1333 MHz (3x2Go) modules, and is my performance rating: 7.0 - CPU and memory to 5.9. I am told by a friend of tech, to improve my memory, because the side of the memory should be higher than the processor for optimum performance. I tried 2-4 GB, modules of 1600 MHz and index performance changed where the memory was higher. (don't remember the # s) Good. However, by doing a performance check with a program of 'notes of the system', he said that memory was not working @ 1600 MHz, but about 663 MHZ and with 1333 MHz, is about 533 MHz. The modules of 1600 MHz were borrowed to test. Now, I'm going to 16 GB (4 x 4) @ 1600 MHz. But, I wonder if this will improve performance, or be a waste of money?
Given that HP specifications say it can handle 16 GB, but only @ 10600 MHz or 1333 MHz, will be 1600 MHz bennifit? Will it work OK.? Thank you my friends, for any input!
You definitely want a number pair of corresponding modules, so if nothing else add another module, as well as the three, you already have. Your score went up when you install modules of 2 x 8 GB because, among other things, allowing memory to run "dual channel", which is a bit faster. Dual channel only works if identical modules are coupled together.
You have already shown that the RAM is unable to run at 1600 mhz, the best it will do is run at 1333 due to hardware limitations. That 533 and 663 are actually half speed. You double this figure because it is the memory of the "double data rate". 16 gigs is a luxury that few computer users really need but if you want to spend money you can.
As a reminder, you can easily install 4 x 4 GB of DDR3 - 1600 but it runs at 1333 mhz but will be dual channel. I don't think that DDR3-1600 is more expensive than the DDR3-1333 at this point and probably more easily accessible. My best advice is to get another module of 2 gig like the one you have.

HP Elitebook 8540w RAM Upgrade
Hello
I am currently in the process of upgrading the RAM in my Elitebook 8540w. I have the i7 Intel M620 (dual-core) and bought the computer in August 2010. I also have Windows 7 Professional 64 bit and 2x2gb (total 4 GB) of RAM.
I watched this document in order to see what the options were: http://www8.hp.com/h20195/v2/GetDocument.aspx?docname=c04150938&ver=25
Now, I see 2 contradictory statements in this document. On page 7, it is said that 8 GB modules are only compatible with quad-core processors (represented by two asterisks) and that it would be possible to have 8 GB (2x4gb) total in my case. Then, on page 18, the table indicates that a configuration of 2x8GB (16GB total) would be possible since there are no asterisks in addition to this configuration.
So who is the maximum I can put in: 2x4gb or 2x8GB?
Thank you!
Hello
The document is for many products for the complete series. Looks like your machine is a machine double heart so it only it supports only 8 GB for 2 slots (the first * indicates 8Gb each slot, and a quad core, you can get up to 4 x 8 = 32 GB).
Kind regards.

HP Elitebook 8540W CPU Upgrade!
Hello
I was just wondering if any1 can help me to make sure that if my HP Elitebook 8540W will support the processor bellow.
http://Ark.Intel.com/products/50067/Intel-Core-I7-2720QM-processor-%286M-cache-2_20-GHz%29
Thnx in advance!
Hello:
The desired processor is not supported as shown in the above messages + there are different system advice even upgrade to a quad core processor, if you have a dual core processor.
BIOS update release notes indicate no added support for the processor you want to switch to another.
Here is the link to the Service Manual: Please refer to Chapter 3, page 26.
Look at the cards system. As you can see, there is a map of system for dual-core processors: 520 M, 540 M, 620 M and a different motherboard for quad-core processors: 720QM, 820QM
http://bizsupport1.Austin.HP.com/BC/docs/support/SupportManual/c02196457/c02196457.PDF
So, if you do not already have a 720QM in your laptop, you can only change your laptop with one of the processors dual-core.

EliteBook 2540p: Elitebook 2540p - RAM upgrade
Hi all
I want to upgrade the RAM in my Elitebook 2540p to 8 GB or (if possible) to 16 GB.
It comes to the information contained in the HP (http://h20564.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c02206692) website:
You are right that the 8 GB is your max.
You are limited by the memory of the CPU bus.
It seems that the CPU of your model can be 8GB.
Memory maximum size (according to the type of memory) 8 GB Types of memory DDR3 800/1066 http://Ark.Intel.com/products/43560/Intel-Core-I7-620M-processor-4m-cache-2_66-GHz

EliteBook 8440p: Ram upgrade problem
I currently have 4 GB of ram, and I recently took a 4 GB stick on another laptop. When I add the new RAM, Windows crashes. The BIOS reads the new RAM (8 in total), but Windows won't load. The new RAM is <4gb 1rx8="" pc3l="" 12800s="" -="" 11="" -="" 12="" -="" b4="">what I've read, the speed max is 10600 on this computer. Is there a way to reduce the RAM? BIOS is locked and not helpful. My questions are: is the speed, the only question? Is there a way to fix this? I would like to solve this legitimately, but if there are other options which may void the warranty, I'd be interested to hear about so, purely for academic purposes.
Thank you!The speed is not the only problem, it's the tension. Your original brief was 1.5 volts and this new memory is 1.35 volts. It can run at 1.5 volt, but prefer not to and you did not provide a part number for the module, but if it is high density (4 black blocks on each side) it will not play nice with the original HP module. Do yourself a favor and get the memory of one of the good sellers, Crucial, Kingston, etc., that is specified as compatible with your specific model. Intel Core of first generation like yours are very capricious in memory.

EliteBook 8540w: identification of Slot Correct memory for twin Enable memory RAM upgrade
I just bought an opportunity Elitebook 8540w with i7 quad core and four memory locations (I love it!). It is running 64-bit Windows 7 Professional he came with a 4 GB memory module and I bought an additional module of 4 GB to 8 GB of total RAM.
I have the HP document that shows both modules of memory of 4 GB, it takes in the memory slot 1 and the other in the memory slot 3 for the proper functioning of the memory double channel. All together right?
Not quite. In the Elitebook 8540w, primary under the keyboard memory locations are clearly labelled '1' and '2' However, the locations of memory expansion on the underside of the chassis are also clearly labelled Opps '1' and '2 '! There is no '3' and there is no '4' in which three vacant slots we installed the second module of 4 GB for the proper functioning of the dual memory channel?
All the facts on how to proceed would be greatly appreciated. Thank you.

Where the second RAM on the Elitebook 8540w location?
Hello, I have the Elitebook 8540w with processor i5 and windows 7 Pro. I bought two 8 GB cards to increase the ram, but can find accommodation with a stick of ram in it.
The manual says there are two slots for ram and it can be upgraded to 16 GB. But the video installation shows a slot under the keyboard. I thought he would have another slot somewhere once I opened and removed the keyboard. But there is no. Also, I opened the compartment in the bottom where other portable store their ram and it was not a slot. My computer said it has 4 GB of ram installed on the computer. The stick I found was only 2 GB, which means that there are another 2 GB key somewhere. Anyone know where and how to get home? Thank you very much.
Best,
Jeremy
You are the very welcome.
This isn't the problem.
The problem is due to your mobile workstation with the i5 processor - it only supports 2 x 4 GB of memory.
You must have the quad core i7 for PC to support 2 x 8 GB of memory.
Please refer to the link below, page 7, double asterisk.

* 8 GB SODIMM is supported only on the quad-core processors.

Upgrade the card video EliteBook 8540w
I have an EliteBook 8540w with the Quadro FX 880 M. I was wondering if it was possible at this level towards the M5800 over-pants and, if so, would I need to change my radiator?
The reason why I want to do is to be able to eventually turn 4 monitors to my office. I'm also open to other suggestions/solutions to achieve this.
I am running Windows 7 32 bit on a Core i7 processor, but will probably upgrade to x 64 when I understand this problem.
Thanks in advance for your answers.

Yes, it is possible to substitute the over-pants M5800. You will also need a new heat sink...

HP Elitebook 8470p A1029D1102: upgrade of RAM 16 GB for p 8470
Hello
I have a HP 8470p (A1029D1102) with 179 KBC Version 42.38 Council. Windows 7 Pro 64-bit operating system.
In fact, I have a 4 GB of installed RAM module and I would switch to 16 GB (2x8Gb modules).
The type of memory suitable for this laptop is 204pin DDR3 (or DDR3L), PC-3, 1600 Mhz 12800.
I don't know if the modules that I will use as upgrade memory must be 'single' or "double" channel.
My question is - is the most effeicient and reliable type of RAM upgrade appropriate for this laptop?
In fact, surfing the web, I found a "kit" (2 modules 8 GB/ea "matched"...) of the A-Tech brand at a very reasonable price (US$ 69.00) but I don't know anything about this brand.
Finally, what are the correct settings to be teaken into account when buying a 16 GB of RAM upgrade in order to have any kind of problem during installation and use?
Quite well, thank you for any help.
The best way to upgrade and purchgase a memory that works as expected during installation is to buy only guaranteed compatible memory modules are a well known manufacturer of memory.
The provider and the memory stand-by manufacturer of their products and ensure they are compatible. They have their name of the game on the market.
Using bandwidth specifications, the type and the ability to buy the memory can be hit or miss and disappointing
oYu will save a lot of time ensuring that the memory that you have selected as candidate for your laptop computer modules are guaranteed compatible. Let manufacturers carry out experimentation in their QA Labs instead of going through the hassle of doing it yourself.

EliteBook 8540w freezes at startup screen Windows after the installation of 2 x 4 GB
Hello
I have a laptop Elitebook 8540w. I wanted to upgrade to 2 x 4 GB 2x2gb RAM memory. I did buy a kit of 2 x 4 GB I wanted, instead, I bought two chips of memory from 4 GB of HP.
After having replaced the modules of the notebook does not start.
What has been done:
-Restore default bios
My first question is: I realize, it is best to purchase a kit of 2 matching tokens, but it's a must?
Thanks in advance,

Hi 2worlds,.
Your Elitebook 8540w is a commercial product and for your question more exposure, I would post in the trade forums. Here is a link to the forum Commercial Notebook.

EliteBook 8540w: Elite book 8540w Windows 7 or Windows 10?
Hi all
I have a HP elitebook 8540w laptop with Windows 7. It is advisable to upgrade to windows 10?
@Mrstenter, I don't think you understand the topic at hand.
HP Support Assistant won't see 10 Windows is a viable OS for this laptop, so, it will not find something for her.
While most of the components have in fact several updates, available from the OEM component, HP has been terrible to sustain this business 'quality' "Élite" mobile Workstation.
The Support Site for the 8540w was a mess, and terribly inconsistent, almost all the time it was available, it's a big reason that when it was time for an update of the platform, I went for a Dell M4800 instead of the EliteBook/ZenBook/s comparible.
Now, @Bredzy , insofar as Windows 10 is concerned; I leave the upgrade happens to mine:
I tried 8 and 8.1 on it and went back to 7 times.
10 has been good so far.
All the drivers I have in place before the upgrade were still in place after the upgrade, which was nice, and same OneDrive is synchronization, despite the fact that I am not connect with my hotmail account.
If you do not rely on the card mobile broadband, you'll be probably a bit stuck here.
I have not tried the once again fingerprint reader, again, because even in 7, the weird mix of validity and ProtectTools jived never really for me, besides, PT integrated only with IE, which I almost never use, so it was pretty useless once the laptop is unlocked at the start.
If you want to get most of your drivers updated before the upgrade, links here is what I use, from legitimate sources (Intel, AMD or Nvidia, HP)
At HP:
Sp67214.exe BIOS F.50 (July 8, 2014)

Choice 2: Radeon Mobile, which works very well
Intel:

I would recommend the driver package, PROSet is not useful for the normal needs of WiFi

Can I change the HARD drive in my Elitebook 8540w for one SSD?
Hello
I have a HARD drive which started making funny noises and I expect to do fast enough. And while that is depressing in its own right, in my view, I better the situation and and put it in a fast SSD instead of the old thing. But before I go and buy the equipment I need to know that it can actually be done. I read another thread on this forum about to put an SSD in the expansion slot (CD/DVD), but I want to replace the main HARD drive. So my best guess is that it is possible, but if there are people here with experience, please guide me in how to proceed.
I made a backup of all my important files so really the only thing I want to do is remove my old HDD and put a new and then install Windows 7 from disks that followed with the computer.
I thank very you much for your time and your help.
Hello
Nothing don't you to replace an old HDD with a fastest SSD 'modern '. In theory, you can use ANY SDS but on the safe side, please use SSD suppliers which guarantees its product will work as the following seller:
The process is very simple (I actually put a Crucial 960 GB to one of my machines today). My suggestion: prior to material things, backup all files/data and prepare a 'big bang' (in my case, I cloned my old HDD so very fast). Please read the following articles for more information:

EliteBook 8540W: USB 2.0, 3.0 &; cd drive is no longer function
Yesterday, I upgraded the HDD for one SSD Intel and flashed the bios to version F.50. After the installation of Renesas Electronics USB 3.0 Host Controller, I rebooted the system to see that none of the work now USB ports. They do not work windows outside. In addition, the network card, wireless and dvd drive has stopped working. The only device which is not affected is the touchpad. System Restore did nothing to solve the problem and now, I'm stumped. The only way to introduce something new would be via the hard disk. Any suggestion would be greatly appreciated that I never met a problem like that. Thank you in advance!
