G62-227CL Notebook memory upgrade

I have a G62-227CL Notebook, and I would like to add memory. What kind of memory will work? Ideally, I would like to add 4 GB to the extant 3 GB. Must I add two of the 2 GB 1066 MHz PC3 8500 DDR 3 modules, or can I add the single 4 GB DDR3-1333?
(I think my system supports 1066 MHz. Does this mean that the DDR3-1333 would work more slowly, or that it would not work at all?) The 4G 1333 module is a lot cheaper than two of the 2GB 1066 modules, so that's why I ask. Thank you for your help!

The single 4 GB stick will work (1333Mz), make sure and insert it into the bottom slot. You can also use the other 2 GB stick with the 4 for a total of 6 GB.
It is advisable to use matched pairs of memory, but it will be fine to mix and match.
Here are some different types of combos from Crucial.

Your machine supports both and the 1333 Mz will be faster, but you won't really notice the speed difference.

Upgrading CPU on G62-144dx Notebook

I am looking to upgrade the processor on my G62-144dx Notebook, Product WA91UA#ABA. I currently have the factory-installed i3 2.13 GHz processor. I have looked at the manual and noticed that the compatible processors with the speeds that I require -- 2.66 GHz and above, to run Sonar X1 Studio software -- are noted for "model 1.1 only." How can I tell if I have model 1.1?
If I do not have the correct model ("1.1"), would one of the "model 1.1"-specific processors still be functional on this computer, albeit with less than optimal performance, or is there another issue (like physically not fitting the motherboard) that prevents such an installation?
Thanks, trying to decide whether or not to keep this computer or to get a custom-made elsewhere.

Hi,
Your machine currently has:
2.3GHz/1.4GHz VISION A6 Technology from AMD with AMD Quad-Core A6-3400M Accelerated Processor
Source: http://support.hp.com/us-en/product/HP-Pavilion-dv7-Entertainment-Notebook-PC-series/5145684/model/5...
From 2.3GHz to 2.4GHz you won't gain anything. But if you wish, you can try 35W processors listed on page #1 of the following document:
http://h10032.www1.hp.com/ctg/Manual/c03043778.pdf
Note: You can't overclock many branded machines. Vendors lock them in BIOS. One understanding reason: they don't want customers overclock machines then after one or two months cunstomers send machines back due to overheat.

Memory upgrade on Satellite Pro A200

Have two Satellite Pro A200 #PSAE1E-00T002EN laptops and wanted to know if I can upgrade the 2 x 1GB memory to 2 x 2GB?

As I understand you request, you want to upgrade the notebooks memory to 4GB.
Well, I think its not possible.
The Satellite Pro A200 supports max 2GB RAM (2 x 1GB) so you will be not able to use 2 x 2GB modules.
Best regards dude

Memory upgrade on Satellite Pro L40-15d

Hi
I have Satellite Pro L40-15d with 512 memory (Samsung) but I wont upgrade to 1GB. I have Kingston ktt667d2/1g I have tray to put in to both slots but nothing work I cant switch on computer.
But when I change for old one laptop is ok. What can I do? Install special program or update BIOS or maybe the memory stick is broken.
Regards

Hi
The notebook doesnt boot after the memory upgrade due to these different issues;
- memory modules are not compatible together
- memory modules are not compatible with the notebook
- memory modules are faulty
- one of memory slots is faulty
In most case the memory module replacement helps.
One hint; did you try to switch the memory modules in the slots? Sometimes this helps.
Several weeks ago I have updated my memory and the notebook didnt boot.
I thought its a memory malfunction but after module switching the notebook booted correctly.
Good luck

Memory upgrade on NB300-108

Looking to upgrade Ram memory to 2gb on my NB300-108
Have looked at Toshiba website and the cost but there appear to be a plethora of alternative websites with compatible memory upgrades when I put in the part number.
Would welcome any experiences of the forum regarding alternatives etc
Thank you

According notebook specification you can upgrade your NB to 2GB. I recommend you to use high quality module offered by Kingston. All info about it you can find here .
I have NB520 so I cannot tell you more about NB300.

Memory upgrade on the NB550D-11D - 4GB RAM are possible

To anyone who's thinking about a memory upgrade on the NB550D:
The NB550D supports up to 4GB of memory, not only 2GB as mentioned by Toshiba in their specifications.
A memory upgrade to 2GB is _only limited_ by the pre-installed Windows 7 Starter OS, not by the netbook itself.
I'm using Linux Mint 11 Katya, 64bit and my system is running perfectly well with a 4GB ram module. If you want to use full 4 GB ram support, get rid of the Win 7 Starter OS.
The specification for higher volume ram is DDR3 1333MHz PC3-10600 SO-Dimm. I've chosen one 4GB module by Corsair, due to the 30 years warranty Corsair offers.
It took me quite a while to find this out, hope this is going to be a help to everybody who's just as unsecure as I was how to upgrade the NB550D memory. Good luck. ;o)

> A memory upgrade to 2GB is only limited by the pre-installed Windows 7 Starter OS, not by the netbook itself.
I can confirm this. Two days ago Ive installed own Win7 32bit Home Premium and upgraded my NB520 with 4GB RAM. 3GB are in usage now and notebook runs perfectly.
With original Win7 Starter version I have noticed annoying display behaviour while watching action movies. When the scene in the movie was without movement everything was ok but by action scenes some strange lines were shown on the screen.
Now after own OS installation everything works perfectly and Im so happy with my NB520.
I can just recommend it for everyday usage.
By the way: I use 4GB SO-DIMM DDR3-1333Mhz PC3-10600

Memory upgrade on U205-S5067

Dear list members,
I have upgraded my notebook memory to 4GB. I have installed Ubuntu 9.04 64 bits version, expecting that the 64 bits version would be able to address all my 4GB or RAM. The problem is that Ubuntu only sees 3.3 GB of memory. Looking up on foruns I found a BIOS option about Memory Remap that should be enabled to support 4GB.
I did not found any option related to memory on bios configuration.
The BIOS version of my notebook is 3.40.
What can I do?
Thank you!

It's all in the data sheet you reference. On page 23 you will see under System Memory Support that the maximum memory supported is 4GB. On page 113 there is the note "All accesses to the memory mapped registers must be made as a single dword (4 bytes) or less" and "To simplify the read/write logic to the SRAM, BIOS is required to write and read 32-bit aligned dwords. The SRAM includes a separate Write Enable for every dword." Also, on page 319 - "The Mobile Intel 945GM/GME/PM and Intel 945GT Express Chipsets support up to 4 GB of addressable memory space and 64 KB+3 of addressable I/O space."
You can get the full story through reading sections 6 and 9 in their entirety.

Memory upgrade on Tecra M7

How do you actually upgrade the RAM on a Tecra M7. This is a new laptop and the correct memory card has already been purchased. I just can't find any technical info in the manual or on the website as to how to physically do this.
Regards
Marion

Hi
On the most notebooks the memory slot are placed at the bottom of the unit but it seems that on Tecra M7 the slots are placed under the keyboard.
may I ask why you suggest the user manual does not provide any information about the memory upgrade???
I have downloaded the user manual from the Toshiba site and found a long and detailed instruction how to upgrade and insert the modules!!!
You should check the chapter 3 -> Features, Utilities and Options -> Memory expansion
Please post again after the replacement.
Greetings and bye

Memory Upgrade for T61

Hi friends,
I have a T61 7663-xxx system, with 1 GB PC2-5300 667 MHz RAM. My Front Side Bus is 800 MHz ( I think so!), Everest software reports my memory controller is dual channel capable, and ~ 85% physical utilization of RAM. I have a nVidia Quadro NVS 140M 128 MB graphics card, but Everest reports 512 MB ?
I would like to upgrade my RAM, and buy some online.
a) Should I buy a similar 2 GB PC2-5300 RAM for my system for performance boost, running Windows XP 32 bit? If so, should I buy Lenovo RAM only, for maintaining my 3 year warranty intact?
Only ThinkPad and Lenovo memory will assume ThinkPad and Lenovo notebook systems limited warranty
b) What are the other best alternatives for good quality, reliable laptop memory, besides Lenovo?
c) Would it be better if I am able to buy RAM which can match my FSB? Will this have any performance benefit? Do these similar FSB speed RAM exist?
Kindly suggest top memory makers, if any.
I could not find any Lenovo 800 MHz memory from their website.
Kindly help me solve my memory upgrade problem.
I am a mechanical engineering student, hence I don't have any idea about FSB and the like, so I request the learned members to cast light on this area.
Info about reputed online sites in US, with fast delivery will be very much appreciated.
Thanks in advance.

Hmm. As far as I know, the internal graphics card can't be upgraded. There's some dock you can buy that lets you add a graphics card for use with an external monitor, but I don't know much about it. The cpu is more likely to be upgradeable, but don't attempt unless you know a decent amount about hardware servicing. Also, make sure the cpu will be supported by the motherboard! Best not to buy one with a clockspeed higher than what Lenovo sold (core 2 duo at 2.6 ghz).
Why do you want to upgrade so much? I run 2.1ghz with discrete graphics and 2gb ram under Vista, and it runs beautifully. If you have integrated graphics, then that might be a bit of a pain, but hey, you've got better battery life!
Anyway, I'd look more into de-cluttering your computer to speed stuff up. Remove anything you don't need, especially Lenovo tools that run in the background and you may not need. Turn off search indexing (slower searches, but faster overall performance). There are some nice guides online, if you google "vista tuneup."
Good luck! Enjoy your T61 as it is! It's a lovely laptop

HP Probook 6450b Memory upgrade issue

Hi All,
I appear to be having a strange issue trying to upgrade the memory in a HP 6450b probook (i5-480m & ATI card). The laptop came with 2gb of p/n sps 598856-002 which is 1333mhz 1.5v ram with the manufacturer being ramaxel. I ordered and fitted a couple of 4gb kingston sticks
http://h30094.www3.hp.com/product/sku/10473659/mfg_partno/KTH-X3BS/4G
Fitted them and all seemed to be well as the OS (win 7 32bit pro) showed the stick as 8gb recognised and 3gb usable, the bios also reports 8gb as well. However the moment a 64 bit OS (Linux or Windows) is attempted to be run the laptop just crashes or hangs
I previously attempted this upgrade with two sticks of crucial memory but had exactly the same problem, so thinking the crucial memory was the issue I returned them to the supplier and ordered the kingstons instead.
I have seen very similar issue noted here:
http://www.tomshardware.co.uk/forum/328016-30-memory-upgrade-probook
and
http://superuser.com/questions/580512/hp-probook-6450b-not-booting-after-memory-upgrade
My gut instinct suggests this laptop may be very fussy about the memory chips, it may have to be a 16 chip 4gb stick as opposed to 8 chip 4gb sticks.
Any thoughts and help on the matter would be greatly appreciated.
Thanks
This question was solved.

You're very welcome.
Glad the lower density memory worked for you, and now you know what to look for the next time you plan on upgrading the memory on any HP notebook made in the last 8 years or so.

Mini 210-2007sl memory upgrade

Hello Sirs,
I wanted to upgrade my Mini 210-2007sl to 2Gb. The original memory was marked:
ELPIDA 1Gb 1Rx8 PC3-10600S-9-10-B1
I supposed some "flexibility" of the hardware so I bought a Kingston KVR1333D3S9/2G, but it doesn't work (screen stays black forever)
Is this related to number of memory chips installed in the module (8 for the original module, 16 for the Kingston part) ?
Could you suggest a compatible memory from Kingston ?
Thanks a lot,
Mario

Memory upgrade on iMac G3 700, help with system crashes

I tried to do a memory upgrade on my iMac, so I bought two kingston 256 MB PC133 modules, but none will work, the system starts, but hangs in about two minutes after loading the desktop. I went back to use the older memory module wich is an spectek, but I need the upgrade, any ideas?
Thanks!
FedericoMG.
Ps: Sorry about my english... I'm from Argentina... :-P

Hi Federicomg
The iMac 700 G3 should have been supplied with 1 stick of 256mb ram. However which is the correct type i am not sure as the Apple specifications for this model state PC100 whereas my iMac G3 700 graphite was supplied with 256 MB PC133-333 SDRAM
http://support.apple.com/specs/imac/iMacSummer2001.html
Apple profiler from my iMac this is the original supplied RAM from Apple:-
DIMM0/J13: Size: 256 MB
Type: SDRAM
Speed: PC133-333
1) I would re-instal the original ram and open system profiler to see what type the ram is.
2) Keeping the original stick in place add another stick of the new ram and look again in profiler to see if its recognised and again try the second stick to see if there's a problem with one of the sticks.
I am currently running my iMac with a small upgrade of RAM and the additional RAM is 128MB of PC100 and i have noticed the performance improvement since adding the PC100 so it's working and i have suffered no ill effects doing this..

MS-6195 memory upgrade

Hi,
My system is based on Ms-6195 K7 pro and Athlon 700 mhz. 192 Mb Ram (128Mb module + 64Mb module)
Problem:
when I try to upgrade memory with a sdram 256Mb PC100 module, the memory test can't finish and my system don't boot.
Please can you tell me how configure coreectly the BIOS or tell how to do.

MS-6195 memory upgrade.
I have also tried using new PC100 256Mb memory and am getting nowhere.
The ones that I have bought are single sided, [8 chips on only one side]
and do not work with my motherboard, however, if I put them into another,
older PC, it shows up as 128Mb.
So I assume that the DIMM is working OK, and that the 'old' PC has a memory size limitation??
I have tried the same things as wbs and Grommit and got the same results.
So I assume that the answer is in getting older DIMMs, double sided with 8 chips on either side.
Does this seem to be about right???

Memory upgrade fail - Kernel panic after put old memories back

I People, this is my first post here and unfortunately is to report a problem, not to help friends.
I did an memory upgrade last weekend. After this, he will not boot normally, only in safe mode.
I discovered that they sent me 1333Mhz memories, and my mac (mid 2009) supports only 1066Mhz.
I put the old memories again, however I believe that the system did not recognize.
As you can see below, the system recognizes two modules:
Memory Module: BANK 0/DIMM0, 4 GB, DDR3, 1067 MHz, 0x80CE, 0x4D34373142353237334448302D4348392020

It is not true, I' using now 2 x 2GB, DDR3, 1067 Mhz (stock)
I tried to reinstall the system, but when I try, I got crash again.
how can I solve this issue?

Hi BGreg,
I already reset the PRAM as you said.
I've cleaned the memory modules as indicated by Linc above.
Today I formatted my harddrive to try a clean install, but system crashs after 5%, 10%.
There is something making me worried:
In one of my tries, I opened the system view to check my actual hardware configuration, and to my surprise, the system shows me 8GB installed. Cannot be. I have 2 x 2GB.
Where my system stores this information? There is a way to reset it? I tried last hour install the snow leopard, that cames with my mac, by DVD, but does not worked too.
Thank you all so far.

Memory upgrade

Hi,
Can I install 2 x Crucial 4GB DDR3 - 1333 SODIMM 1.35V 204 PIN - CT51264BF1339J on a Macbook Pro 13 inch late 2011?
Currently, I have 4 GB (2 x 2 GB) and I want to upgrade to 8 GB. There is a controversial info regarding this particular memory module, some people say it is not compatible.
When I look to the specs I find:
204 PIN form factor = OK
1,35 V = OK
DDR3 = OK
1333 = OK
SODIMM = OK
Max 8GB = OK (2 x 4GB)
Latency= 9 cicles (same that stock modules supplied with the laptop) OK
The thing is Crucial, sell an identical specs module that costs quite more. They claim it to be compatible with Mac. The also sell this one I mentioned as being not compatible. The funny thing is that specs for both are identical. I only find a difference on the pricing. So I am really confused.
Do they one to sell me a more expensive one like being specific for Mac or there is a hiden specification that makes the two modules to differ from each other?
Can somebody confirm this info to me, please?
Many thanks in advance
Best Regards

News on this subject:
A Crucial support representative replied saying:
"Mac compatible memory is guaranteed to work in your specific system. There may be subtle differences in non specific memory that will cause it not to work for you such as chip solution and the configurations of chips..."
Well, I find it very ambiguous technically speaking. If they sell good quality memory as they claim, I do not see which subtle differences will affect the functionality. The chip configuration is standard and chip solution is about quality. So Crucial should be all right as everyone claims (even if manufactured in China)
So I went a head and both 2 x CT51264BF1339J for a very reasonable Belgian price and installed it into my system just two minutes ago. I am writing this using the mentioned system.
I was on Google after 30 seconds of taping the On button. Although it did not changed a lot as this startup timing is more related to the Hybrid 750GB HDD (SSD + Conventional Drive) I upgraded few months ago.
I upgraded the memory to run Virtual Box and Parallel desktop more easily though it worked quite good with 4GB. I did not upgraded to 16GB because it is not necessary on my usage. Only one virtual machine at once + E-mail + Browser + some PDF opened. Some technical stuff and nothing like Photoshop or similar. Thus the huge money difference would have gone for nothing if I buy the specific Mac modules of 8GB each as "Crucial Memory Upgrade Tool" subjected me.
