T430 RAM upgrade to 16/32GB

Hi,
I want to upgrade my t430 Laptop to 16/32 GB RAM. When I purchased this laptop, Lenovo store told me that this laptop has only one open RAM slot and he added 8 GB RAM and told me that we can not upgrade this laptop to 16/32 GB RAM. But I have a doubt because in the laptop specification it is clearly written that this laptop can be upgraded to 16/32 GB RAM...Can somebody provide me clarity about it.

So what is the final Verdict ?
The jury is still out.
There are at least two issues currently being deliberated by the jury that preclude a final verdict
1. Even if the chip architecture supports 32GB the motherboard in the T430 may not.
2. Even if the chipset and mobo support 32GB you can't buy 16GB SODIMM modules.
Why do you feel you need more than 16GB?

T430 RAM upgrade

Hi,
I just ordered a T430 with base RAM of 4GB in 1 slot. I am thinking of buying another one of 4GB. I read through the previous threads and couldn't find an answer to the fact that which Crucial RAM should I go for

http://www.crucial.com/store/mpartspecs.aspx?mtbpoid=159064DCA5CA7304
The difference is of voltage one is 1.5 V and the another one is 1.35 V .
P.S.: I am assuming that having two RAMs from different manufacturers but same configuration won't have any issues. Please correct me if I am wrong. Any other suggestions are welcome.
Cheers,
Rachit

Here's what Crucial has to say about this issue: 1.35v - 1.5v Dual-Voltage DDR3 memory.
My advice is the same as Crucial's. Buy the same voltage rating as the 4GB module you now have.

Intel Rapid Start stops working when RAM upgraded

I have a brand new ENVY dv7-7212nr notebook running Windows 8 64-bit.
This machine has Intel Rapid Storage Technology which caches hard disk data (I think on the 32GB SSD) and Intel Rapid Start Technology which stores active memory in the SSD cache (I think) when the computer enters a hibernation state.
The first thing I did was upgrade the RAM from 8GB to 16GB. It works fine, but then I get an error message "your system does not appear to have intel rapid start technology enabled."
HP provides very little information on this, basically none. I assume the memory is being cached on the SSD, but I don't know how to verify this. Also I notice that acceleration is not enabled under the Rapid Storage Tecnology applet for either drive.
I called tech support twice but the techs knew nothing about upgrading RAM beyond the usual and couldn't get it to work either.
Does anybody even know exactly how the SSD is being used in my system? That would be valuable information to me.
Thanks in advance!
This question was solved.

Thanks for reading my reply.
The "little SSD" is still a drive and not a chip, although you are right that it is little and it is attached to the motherboard. It is little because its form factor is not the typical 2.5 inch size but what's call "mSATA". In fact, the service manual for this dv7-7212nr laptop shows you how you can remove and replace or upgrade this mSATA SSD:
Below is a comparison of how small the mSATA form factor is to other drive sizes (from Left to Right: mSATA, 1.8", 2.5", 3.5"):
So if I want to replace the mSATA 32 GB SSD with a 64 GB SSD, I would have to get a mSATA SSD, not the typical 2.5" ones. So for this dv7-7212nr laptop, there can be 3 total drives installed: one in the mSATA slot and two in the 2.5'' drive bays. However, the default configuration as sold by HP only has one mSATA 32 GB SSD and one 750 GB SATA hard drive, with the remaining drive bay empty.
This dv7-7212nr laptop does contain all the latest (and perhaps more complex) technologies and HP probably does not expect the typical user/consumer to go and muck around all the default settings. However, if one is curious and willing to make the effort to learn, the material is just a google search away.
Here are the instructions for setting up Intel Rapid STORAGE Technology (aka Intel Smart Response Technology): http://download.intel.com/support/chipsets/sb/intel_smart_response_technology_user_guide.pdf
For this dv7-7212nr laptop, you can ignore steps 1-4 because the BIOS is already configured properly from the factory (unless some changes were made by the end user).
Here are the instructions for setting up Intel Rapid Start Technology:
http://download.intel.com/support/motherboards/desktop/sb/rapid_start_technology_user_guide_v11.pdf
For this particular laptop, ignore steps 1-7 but it is important to do this first: set up Intel Smart Response Technology as above, making sure to allow enough space on the SSD for a hibernation partition that is equal to or greater than the total size of RAM installed. Then follow steps 8 to the end of the guide. It is important to set up Intel Smart Response before Intel Rapid Start because Intel Smart Response will destroy all partitions and data on the disk (if you set up a hibernation partition for Intel Rapid Start first, it will be removed when you set up Intel Smart Response).
I have successfully ENable and DISable these technologies on my laptop using the above guides (with my modifications). WARNING: back up all data before trying any of this.
In your case, I agree that you can also disable Rapid START and just use the whole SSD for acceleration along with the 16 GB RAM upgrade.

The culture is changing with the ability to upgrade the newer machines. I've noticed a lot of people on this forum more closed to the idea of upgrading, most are unaware it can even be done, which is sad in my opinion. Maybe because this is the official support forum. But the other mac sites are like what I'm used to in the past working with pcs:
check out these:
http://forums.macrumors.com/showthread.php?t=1323028

http://www.hardmac.com/articles/335/page1
the list goes on.
etresoft, we know that mac computers are the best...period. Hardware upgrades are also better for some of the same reasons that make apple computers better; not as customizable -- only certain upgrade paths are possible. Upgrade process more difficult because of mac's intricate design. But once you do the upgrade right, it just works beautifully. And you extend the life of you machine another two years at less than half the cost of getting a new mac.
Open you mind brother. Apple has done everything right, this is just another part of their strategy and I think it's great.

Thinkcentre M92P, RAM upgrade options

I have a ThinkCentre M92P 2992D9G. Currently it has the factory shipped 4GB RAM aboard, but I would like to upgrade the RAM.
Crucial is giving the options of DDR3 PC3-12800 Unbuffered NON-ECC 1.5V 1024Meg x 64 or DDR3 PC3-14900 Unbuffered NON-ECC 1.35V 1024Meg x 64 of various sizes whereas when I check on Lenova it shows me the 12800 versions only. I would prefer to get my RAM from a UK source (why does Lenova take me to a US site?), but I want to make sure that whatever I get is compatible. Is there anything to be gained by paying a little extra for the 14900 versions or will the system treat it as 12800.
I note that the system seems to be quite happy about not having memory installed in pairs, so I was thinking of getting an 8GB module taking me up to 12GB but offering the flexibility to retain the 8GB as part of a future upgrade to the 32GB maximum if ever it becomes necessary. Would 4GB + 8GB work or would 2 x 8GB (taking out the 4GB) be a safer option.

Both Crucial and Kingston "system specific" memory is guaranteed to be 100% compatible with your system. Nothing to be gained by going with faster memory on this system since overclocked memory is not possible. The chipset supports 1600 MHz max.
Installing one 8 GB module with the 4 is an option, but access above 4 GB will be single channel and slower than the dual channel that would be below 4 GB.

Which configuration of iMac 27" ? Fusion drive or not ? RAM upgrade ?

I'd love to get a new 27" iMac for my Mother, but cannot decide if the higher i7 processor (3.5) is worth the price, and cannot decide if the 3TB "Fusion" drive is worth the extra $350.
The retail Apple stores stock the i7 only with the 3TB Fusion drive, the better graphics card, and stock 8GB of RAM, but one can configure the machine if ordering on-line via the link below. Her husband will reimburse me or it will be a gift. Money is not the issue.... just whether or not the money is worth spending.
One last thing: The apple store rep said that the "Geniuses" have to do the RAM upgrade, say from 8GB to 32GB because the 21" unit has to be opened. So the consumer doing the RAM upgrade will void the warranty. Yet I see website indicating that the 21" has a nice convenient door to open and the RAM is user-upgradable without voiding the warranty. Which is true ?
Apple wants to charge $600 (parts and labor) for the RAM upgrade to 32GB. But Crucial has 32MB of this RAM for under $300 with a lifetime warranty. Is there a reason to use the RAM from Apple ?
LINK: http://store.apple.com/us/buy-mac/imac?product=ME089LL/A&step=config

1. 27" iMac with 3.4Ghz i7 and NVIDIA GeForce GT 775M with 2GB video memory is just $200 more than 27" iMac with 3.2Ghz i5 and NVIDIA GeForce GT 755M with 1GB video memory. How much is her time worth per hour? If it's for business use, it pays for itself quickly. Same opinion for the 'build-to-order' upgrades in speed and video available on the 27" i7.
2. Fusion drive is a hybrid combining 128GB SSD with either a 1TB or 3TB rotating platter hard drive.
Analysis and review of Fusion drive in a 2012 iMac: http://www.anandtech.com/show/6679/a-month-with-apples-fusion-drive
Conclusions and performance are on pages 5 and 6 of the review.
3. 27" iMac RAM is "user-replacable", quoting from the 2013 'Important Product Information' addendum to the manual:
"Do Not Make Repairs Yourself
Your iMac doesn’t have any user-serviceable parts, except for memory, which is user-replaceable in 27-inch models only. Do not attempt to open your iMac. If your iMac needs service, contact an Apple Authorized Service Provider or Apple for service.
If you open your iMac or install items other than memory in 27-inch models, you risk damaging your equipment. Such damage isn’t covered by the limited warranty on your iMac."
quoted from http://manuals.info.apple.com/MANUALS/1000/MA1662/en_US/imac_late2013_ipig.pdf
OWC video of the 27" RAM upgrade installation: http://eshop.macsales.com/installvideos/imac_27inch_late_2012_mem_m/
4. If it's for business, go for the i7 and the video upgrade.
5. I'd do the upgrade myself, purchasing from a reliable vendor of Apple RAM such as crucial.com or macsales.com. I have no experience with the other vendor you mentioned, RAMfinder.com. Factory-installed RAM offers the pricey convenience of having a machine configured by you online and shipped directly to your mother in a few days with no one else needing to be involved. I'd avoid any Apple salesperson who apparently doesn't know the 27" iMac product well enough to give you the truth about user-installable RAM upgrades. OWC (macsales.com) will purchase system-pull original RAM allowing you to recoup a small portion of the cost of the upgrade, though nothing close to the resale price of the RAM.

First go to the RIM web site and look to see if they have an uninstaller for the device you had. Some times a reinstall of the application and then running the uninstaller is required for complete removal.
If no uninstaller is available, then you will have to use Spotlight to find all items with 'Blackberry' and 'Rim' in the titles. I would also download EasyFind and use that to locate such files. Often it will locate items that Spotlight misses.

HP Envy 13 1030nr. Windows 7 64-bit. RAM upgrade help.

I just purchased a RAM upgrade for my Envy 13 and I was trying to figure out how exactly to access the memory module. I couldn't find a youtube video for the Envy 13 and reading the maintenance manual provides only partial instructions to access the memory module. It tells you what you need to do (Disconnect the TouchPad cable 2 from the low insertion force (LIF) connector on the system board) but not how to do it without damaging the computer. I don't want to permanently sever a cable or anything so I'm looking for help via a link to a video or more detailed instructions on exactly how to safely access the memory module.
I was under the impression that this would be a quick replacement, but the more I read the manual, the more I think that this is going to be a little more complicated than opening up the bottom and removing the current RAM chip and replacing it with the one I have. Any help would be appreciated. Thanks!

Here is the Manual:
Manual
Memory is indeed on the motherboard and getting there requires nearly complete disassembly. See Page 4-26. Not sure how this qualifies as "easy" and if you have not done this before you should get some help. And yes, keep careful track of those screws.

Hard Drive and RAM upgrades for latest 15" MBP

I'm minutes from ordering a new MBP. Only concerns are whether I get hte Apple upgrades or shop around.
I like this Hard Drive...
http://www.compu2000.com/index.php?l=product_detail&p=6433
And this RAM upgrade...
http://www.a-power.com/product-10937-311-4
If these are equivalent to the apple options I can save hundreds and get a 320 GB drive, which will make a great portable.
So, does my plan hold water?

You're on your own for support when you do your own upgrades like this, but generally speaking, it works fine.
Note that HDD is less risky than RAM. With RAM you run the risk of unstable behavior that is tougher to diagnose. That said, a quality RAM upgrade and some initial testing with any of many available tools is as good as a factory build.
HDD upgrades are less risky, and I've upgraded (well, replaced after HDD death) ones in my MBPs many many times. I crunch my hard drives more than normal and have to generally replace them about every year. Some of the MBPs don't make this easy, and prepare to get all sorts of cozy with little 0 and 1 sized Phillips screwdrivers and some T6 as well, but it is doable (just not quite for the truly faint of heart).
Again, you're on your own for support once you do this, so weigh that in your decision.

This is the regular status of the memory of my macbook pro. Do you think I need a RAM upgrade?

Hi there,
I'm hoping to seek the expert views of the community here.
I have a MacBook Pro, Late 2011, 17 inch. Running latest version of Mavericks. Speed seems to have slowed somewhat, perhaps since I upgraded to Mavericks, but not certain about that. Based on my research of the Apple communities, I suspect that I may benefit from a RAM upgrade.
Attached are a few screen shots to assist:
Based on what I have researched in the community, the fact that I have used 3.99GB of 4.00GB, and have used 5.63GB of Virtual memory, seems to suggest to me that I have well and truly maxed out my RAM. Also there is a high number of read ins/outs (but it had been a wheile since I last did a restart on the MBP (if that has any effect on these numbers here).
I have also read that my model of MacBook Pro is upgradeable to 16GB of RAM (2 x 8GB).
Thoughts and views from the community would be greatly appreciated. Will additional RAM help the speed and performance of my MacBook Pro?
Many thanks.

More RAM is always a Prudent move...

Those sites also have videos on how to Install RAM should you need it....

Video will not play on Canvas or NTSC after RAM upgrade

editing on a G5 v. 10.4.11, Dual 1.8 Ghz G5 with a recent upgrade to 4GB of ram. Have an AJA IO LA
After the RAM upgrade, FCP timeline will play but video is black in the canvas and image is frozen on the NTSC. Video WILL play in Viewer but no audio.
All cables have been checked to make sure they were put back correctly - will keep checking for errors in re-cabling computer.
Have tried refreshing displays and other tests with displays. Any info would be greatly appreciated.
Thanks!

pull the ram, problem goes away? - bad ram
you can pull 2 sticks at a time to isolate which chip it is.
did you get it from a good source - Crucial.com is my favorite, OWC is popular too - both have lifetime warranty

24" iMac (Primo 2009) strange RAM upgrade issue

I have a 24" iMac (Primo 2009) at work. I been granted a RAM upgrade by the IT department and have received 2 indentical 4 GB modules.
The 24" iMac (Primo 2009) uses 1066 MHz DDR3 modules and supports up to 8 GB RAM in 2 slots. I have purchased RAM from this source http://www.dustin.dk/product/5010642132/corsair-4gb-ddr3-1066mhz-1x4gb-so-dimm-i mac-macbook-macpro/#intcmp=searchProvider_SiteSeeker (Corsair Mac Memory so they SHOULD be fine.)
Here's the issue:
I had 2x 2GB modules. I have taken both out.
I have inserted the new 2x 4GB modules but the machine refuses to boot. It gives off 3 beeps-interval-3 beeps-interval (repeats).
I took out one of the 4GB modules from slot B. It boots.
I inserted the one I removed in slot B again so we're back at 8GB. same beeps. No boot.
I switched the 2 4GB modules from slot A+B around. Now beep-interval-beep-interval (repeats) No boot.
I inserted one 4 GB in slot 1, and one of the old 2 GB in slot 2. It boots with 6GB RAM.
I inerted only the one that won't boot when in slot B in slot A, beep-interval-beep-interval (repeats) No boot.
OK - so logical deduction tells me one of the new 4GB RAM modules is defective. No matter what configuration, booting fails with that specific module inserted, though there are different beeps. I also know tha both slots work since the machine works with 6 GB RAM (2+4).
So I called Dustin, and since we're a big customer they sent a new moduel for free. But, I have the same isssue with the new module!! What are the chances I have recived 1 working and 2 defective modules? not big right? So my iMac seems fine with the old 2GB modules and one of the new 4 GB modules, but says no to the 2 other 4GB modules.
YES - I have tried resetting PRAM and SMC to no avail. Any clue?

Switched the 2 modules around, so there's now a 2GB in slot A and a 4 GB in slot B. Still works fine
