SSD (Solid State Drive) Upgrades and DV7 4280US

I am posting this as an FYI for anyone who is considering upgrading their DV7 or similar laptop with a SSD.
My experience with this has been somewhat difficult and I am hoping this will help.
I own a DV7-4280US laptop with 6GB of memory, i5 processor, and an 750 GB 5400rpm drive. I decided to put a OZC Vertex 2 120GB drive in it to replace the main drive. I decided to do a fresh install of the factory image directly to the new drive. This failed. I was able to run the HP recovery disks and get all the way through without an error, but was not able to boot. The system stated that there was no valid boot disk. I tried several times with different options and always got the same error message when I tried to boot from the SSD.
The solution for me was to use partition wizard home edition (http://download.cnet.com/Partition-Wizard-Home-Edition/3000-2094_4-10962200.html?tag=mncol;1) and to copy partition #1,2 and 4 over to the new drive (from my old drive in an external enclosure) resizing appropriately so the data all fit on the newer smaller drive. I was careful to make sure each partition was created as a primary partition not a logical one. I also had to make the first partition active as it contained the boot info for Win 7-64bit.
A note about partition size: before I copied the partitions over, I decided to uninstall some of the extra software I did not use that came from HP and a few that I had installed. I also deleted all of my temporary files and did a disk clean up. It is best to not fill your new SSD too quickly and to do as few writes as possible. It is the writing that consumes the drive over time and even if you copied the partition and then uninstalled and cleaned up you will have still consumed some of the life of your drive. I was able to trim my C: drive down to about 30 GB and have a lot of space left in the 111GB of that partition.
My guess is that the problem with the HP restore disks is that they for whatever reason did not set the first partition as active on the SSD. I have not been able to figure out why because they would do this correctly if it were any other type of drive. Maybe this is a bug with that restore program.
I also found that doing a fresh install of Win 7 form a microsoft disk works fine too.
I have been told by OCZ that if I have enough memory (4GB +) that I should set the page file to "No Paging File" in the advanced system settings. This will conserve the SSD as they have a limited number of writes and over time the page file will consume a good portion of it's life.
OCZ and Microsoft both recommended that I run the Windows Experience Index immediately after installing the SSD because it will turn off several prefetch and caching services that you will not need with your new SSD.
I have been super happy with my new SSD and am absolutely convinced that it is the very best upgrade you can do to speed up your system. My windows experience index went from 5.2 to 6.7 the disk is now rated at 7.6. Windows now loads in about 8 seconds and web pages are almost instantaneous. It is well worth the 200 I paid for the drive.

Hey...thanks for the information - I wish my search had come across your post earlier...it would have saved me a couple days of pulling my hair out! I just bought a DV7-7298 (i7, 1T HDD, 12GB RAM, Win8 pre-installed) and similarly wanted to install an SSD (Intel 335 240GB).
The recovery disk option for intalling Win8 on the new drive got me nowhere at all - it would not boot except for once and I had no networking and major software installation issues which forced a reboot sequence and more terror...horribly frustrating and HP was absolutely no help. I had a Windows 7 disk that I was able install on the SSD but no clean Win8 disk. I called Microsoft (who were quite helpful) - they were happy to allow me to download a fresh copy of Win8 with my existing Win8 Product Key...great, I thought...
With some aftermarket software I found the Win8 key which is attached electronically to the BIOS on these new machines - no more Product Key stickers on the bottom of our machines...the problem is that the OEM Key was not accepted by the Windows site to allow me to download the clean Win8 software...argh! In the end, Microsoft helped again by agreeing to mail to me a Win8 install disk (which I though was decent of them)...not a quick solution, however. In looking for solutions, I came across the Microsoft Win8 Pro upgrade offer ($40 until Jan. 31, 2013) - in order to potentially get this done, I decided to spend the $40 and get the upgrade which I downloaded and installed immediately...in the end? Success!! But not quite so fast...I had to install Windows7 on the SSD first in order to run the Win8Pro install which I'd put on the 1T drive that came with the machine - put it in an external drive...it installed without any issues. I downloaded the drivers that Windows missed from the HP website and now have a slick, extremely fast notebook without all the bloatware...so sweet!
It is amazing just how fast these drives work - no regrets at all (except for the wasted time getting it working)...this is a great performance upgrade - if you want a faster machine and quick boot, this has got to be the best bang for the $! With this DV7, I can still have the 1T drive in the second bay (battery power isn't a problem for me) so a lot of my data will be going there with programs on the SSD. If you're considering this upgrade - great - do it for sure! But do yourself a favour and don't waste time with the HP recovery disks...they just don't work for this upgrade...find someone with a clean Windows disk (XP, Vista (ugh2), 7 or 8) and install your OS that way. If you have the UEFI BIOS Product Key set-up - it should activate itself (Win8).
Best of luck - you'll love the results!

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
Memory Module: BANK 1/DIMM0, 4 GB, DDR3, 1067 MHz, 0x80CE, 0x4D34373142353637334648302D4346382020
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.
Giuliano

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.

Memory upgrade not working

I ordered 8GB memory for my imac mid-2011 model.
I then tried to install and all I'm getting is three beeps telling me there's something wrong with my memory.
I've tried all configurations but can't get the 2x4gb modules to work.
I've had to stay with only the original 2x2gb ones it came with.
Can anyone please help.
The only difference, besides the size, between the two modules is that on the 4gb ones is says PC3-10600S-9-10-F2 and the 2gb ones say all the same except instead of F2 at the end it's F1.
Cheers.

Which would seem to suggest that you may (unusually) have a doubtful memory module. Less unusually, you would have paid over the top for it.
Many people on these forums speak well of the following suppliers.
In North America contact OWC … Upgrade Apple iMac Memory
In Europe contact Crucial.com … RAM Memory Upgrade
Both companies have facilities to guide you and will recommend the correct memory package to meet whatever needs you describe to them.
There may be benefits buying from your own geographical location insofar as Shipping charges, Local sales taxes and Exchange rates. Check out the basic memory costs and do your sums next time you buy.

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 Satellite A50-104

I NEED TO FIND A 512MB MEMORY UPGRADE FOR MY A50/104 ANYONE NO THE CORRECT ONE TO BUY, I WAS TOLD ON EBAY THAT 512 DDR SODIMM IS THIS RIGHT. ALSO HOW DO I CHECK ON MY LAPTOP FOR THESE DETAILS IF THERE ARE ANY AND ANY OTHER SPEC BATTERY ,HARDDRIVE ETC

Hi
You have several ways to find out what memory module is compatible and supported.
You can use a diagnostic too like Everest, you will check the user manual or the Toshiba website for details or you will contact the service in your country for supported modules.
I will try to answer the question: The Satellite A50 should support PC2700 DDR-RAM like these parts:
PC2700 256MB (PA3311U-1M25)
PC2700 512MB (PA3312U-1M51)
PC2700 1024MB (PA3313U-1M1G)
Now its your choice. You can also google for the offers
By the way: Visit the Toshiba Options & accessories site. There you will find compatible parts

Memory upgrade on Satellite Pro A40

Can anyone please advise where is the best place I can get a memory upgrade for my Satellite Pro A40 laptop.
I think my machine is a PC2700 DDR. I am looking for either 512mb or 1gb.
Thanks in advance.
Christine

Hi
On the Satellite Pro A40 you will find 2 memory slots and you can upgrade the memory to max 2GB (2x1024MB)
It should be possible to use these modules:
PC2100 512MB (PA3164U-1M51)
PC2100 1GB (PA3278U-1M1G)
And
PC2700 512MB (PA3312U-1M51)
PC2700 1024MB (PA3313U-1M1G
I purchase the compatible parts and devices always form the Toshiba service partner in my country because so I'm 100% sure that this parts are compatible.
So I would recommend you also to buy the modules form the ASP in your country.

Memory Upgrade on Satellite Pro A60

I have upgraded an A60 Pro with a 1GB memory up but the Control Panel /System/ General tab still shows it as having 192MB RAM. This limits me downloading some Security Software from BT Yahoo.
Can anyone advise on how I can make the machine recognise the new RAM or is the 192 MB RAM noted different memory from the new memory upgrade?

If you use non-compatible RAM module it is logic that system can not recognize it correctly. I do not know who is the manufacturer of this 1 GB RAM module but if you want to use compatible one pick up some info about PC2700 1024MB (PA3313U-1M1G) or check Kingston web page.

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 DV7T-3000 (NQ339AV)

Hello,
I have a Pavilion DV7T-3000 with i7-820QM Processor. I am planning on a memory upgrade. Has any one tried upgrading it to 16GB RAM ? (2 x 8GB). As per specs it can only go up to 2x4 GB.
Thank you for for any feed back.

I believe you should try to PM a level 8 or higher expert here and see if they will access someone from HP.

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)

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 for Satellite L30-134

I have a Satellite L30-134 which appears to be running quite slowly - I think due to large amount of photos and itunes music.
I am wondering which is the easiest way to resolve - buy a memory upgrade (no idea how to change the memory though) or get an external hard drive?
And if I change the memory will I lose what is already saved on the laptop?

I agree with Ganz the bigger HDD will not improve the performance but only increase the available HDD space it would helps you to store more music and pic files on the HDD ;)
The memory upgrade would also not bring an performance boost of course the performance would be a little bit better because the most stuff would be handled directly in the memory and not temporally on the HDD but generally its not really noticeable.
Anyway if you want to upgrade the memory check this:

You have to use DDR2 533MHz (PC2-4200) 200-PIN SODIMM
