Windows 7 not booting with 4gb ram

Hi!
Situation:
I installed Windows 7 via Bootcamp. On 2gb ram (2x1gb or 1x2gb doesn't matter) windows boots fine.
I upgraded to 4gb ram (2x2gb) and now Windows is not booting. As far as I know, it's not even getting in DOS.
There's just the cursor blinking into infinity...
What I've tried so far:
Installing windows with 2gb and ugrading to 4gb.
Installing windows with 4gb
Tried the 32bit and the 64bit version
Found a 'solution' on the web making me boot in safe mode in order to change the maximum ram windows accepts.
Attributed more gb to the windows partition
I'm out of ideas, what do you think?
regards,
Massimo

More detail and a reply for the CQ50 - 130US will not boot with 8gb ram post

The specs, on the web site say that the max memory supported is 3GB DDR2 because the notebook was built with the OS Vista(32 bit) installed so that’s why the manual has the 3 GB max. memory supported limit. The 32 bit OS can’t address memory over 3.12 GB. To my mind that is not a spec. but rather a tech. writer who made a mistake and copied the sales literature. With Windows 7(64 bit) Pro. installed the OS can address up to192GB of memory if the system supports it. Other Compaq and HP Notebooks can deal with 8GB of memory installed. That’s why I would think HP’s could easily fix this with a patch or use one of their other BIOS’s.
The difference between 4GB and 6GB is that with 6GB system runs faster and the display quality has improved. I have set the cache size to large and the executive paging is set to off in the registry. The menu(System Properties - Performance Options – Advanced – Virtual Memory) is set to automatically manage the paging file size.

You should keep it in the original; thread you started.

Computer will boot and recognize 3 GB..( Apple 1 GB + 2 GB GEIL)
Both Geil Chips will boot, when paired with the Apple 1 GB chip.
machine recognizes 3 GB ram.
Please advise...

Ensure the computer's RAM is fully seated down, and then try resetting the PRAM by holding down options-command-P-R at boot. The computer will make the boot chimes and then reset and chime again. When it chimes the second time release the keys and let the thing boot normally. Hopefully that will let it recognize the RAM.

Virtual Windows 7 machine with 4GB RAM

I'm currently upgrading my iMac to 8GB RAM, I have a 2.66GHz processor , will I be able to install Windows 7 in a virtual machine using VMWare Fusion 4 with 4GB of dedicated RAM?

Sure, why not.
Depending on your usage you might wanna rethink the amount of RAM you assign to the Fusion Windows VM.
Windows 7 runs quite well with 2GB for example whne you usage is the more "Office-like" one.
Keep in mind that the amount of RAM you assign to a Fusion Windows VM is not avaiable to Mac OSX until you close the Windows VM and Fusion.

Re: Satellite A200-1K7 - Doesn't boot with 4GB RAM

Hello,
I am trying to upgrade to 4GB of RAM. According to the manual my Satellite A200 1k7 does support up to 4GB of ram.
However, if I place two 2GB modules the computer won't turn on. Either one of the 2GB modules on it's own works fine but the two of them together won't work.
The power light turns on, the harddisk whirs and then goes quiet. Nothing happens, not even a BIOS screen.
My BIOS is up to date. I am using windows Vista 32 bits.
The memory modules I use are both SO-DIMM DDR2 PC2-5300 667 Mhz.
Please help!

Im not sure but as far as I know the Satellite A200-1K7 has an Intel 943GML chipset that supports 2GB max.
So you should check which chipset you have. For this you can use PC Wizard 2008 (http://www.cpuid.com/pcwizard.php).
If you have an other chipset I think the modules are not compatible and so you need other modules.

P7N Diamond - Can't boot with 4GB Ram (no picture)

I wonder if there's any settings I need to modify in order to make my system to work with 4 gigs of ram (4x1GB) ?
Is there any known issues I should be aware of?
I really appreciate any help I can get!

Sorry about the lack of info, I tend to rush things when I get frustrated.
I bought two kits at the same time, as far as I know they are identical. I haven't played around with the BIOS apart from adjusting the voltage to 2.1 (which didn't improve the situation)
It does boot fine with two sticks, as well as three.
Any BIOS settings that comes to mind?
Let me know if you need more info!

Re: Satellite Pro A200 - Won't boot with 4GB RAM

Hi,
I've installed 2 x 2GB, but it seems it doesn't work. The funny thing is that when running just one memory strip (so 2GB) it works, when running both it doesn't work and it freezes. These are the Samsung 2GB 2Rx8 PC2 - 6400s - 666 - 12 - E3
Ive' installed the latest BIOS update (64bit v2.60) for the Satellite Pro A200 and I am running Windows 7 64bit

Hi caribman
What Satellite Pro A200 you have exactly?
I ask this because some A200 models were equipped with Intel 943GML chipset and these models support 2GB only!!!

Macbook pro does not boot after upgrading ram

I have a macbook pro late 2011 which runs with mavericks operating system . I have tried to upgrade my macbook to 8Gb. Macbook does not boot when the two ram slots are filled with 4GB ram but runs well when the slots are filled with 2GB ram. When i try them individually with one slot of 2GB ram and another slot with 4GB they run perfectly which shows status ok in the RAM info. What could be the problem .

Around here, most of us recommend only Crucial and OWC for RAM because it's guaranteed to work with Macs and it's what most of us have. If I were you, I would return the RAM and look at purchasing RAM from either Crucial or OWC. If you can't get their RAM to work then you'll know that there's some trouble with your actual slots.
Good luck,
Clinton

Any suggestions, or fixes, as to why I have to rebuild my library after EVERY shutdown? I am running the latest 10.6, 2.92 ghz iMac core 2 duo, with 4gb ram.

Any suggestions, or fixes, as to why I have to rebuild my library after EVERY shutdown? I am running the latest 10.6, 2.92 ghz iMac core 2 duo, with 4gb ram. Install went well, as far as I know. No other problems. I fear, that unless I fix this, when I upgrade to a new computer, I will be taking the same problem with me.

So if you start Aperture do some stuff in it, quit, then open Aperture again it starts up OK but if you then quit Aperture, reboot your machine and start Aperture it stalls?
You're internal drive is getting close to being overfull your at about what 18.5% free space (some we'll say it's already overfull). You might what to think about freeing up space. If you weren't having any troubles I'd say it was fine but as you are experiencing problems it is something to look at.
While its been doing the processing have you been able to open the activity window in Aperture? If you click on the spinnig gear (not the beachball) when Aperture is busy you can usually get the activity window to open.
Other then that not sure what else to recommend at this point.

I got a MS-7253 k9vgm with 4gb ram and W7253VMS.180 BIOS but I only can see 3GB

Hi,
I have a MS-7253 with 4gb ram recently installed on it but in bios memory check state it only shows 312something KB (3.2GB) and BIOS is the latest one.
According to MSI's site, this motherboard is supporting upto 4gb. I've turned off the on board vga as well and my vga card is an nvidia geforce 8400GM.
the funny part is windows 7 recognize the whole 4gb but it says I only can use 2.8gb of it.
whats wrong with my M/B? is there any other update which I'm not aware of?

Thanks for your reply,
does that mean there is no chance for upgrading ram to 4g? or by BIOS update I can do that?
I have found another BIOS update newer than what I've got from this link: https://forum-en.msi.com/index.php?topic=153338.0
just in case if I screw my BIOS can I revert it back to what it used to be?

MBP15 1.83 GHz Will Not Boot With 3GB Upgrade

I'm trying to increase my MBP's ram to the 3GB limit. This is a 1.83 GHz 15" model.
It will not boot with 2GB & 1GB sticks of identical mfg & specs. It will boot with one or the other...
Any ideas?
Thanks,
Stradioti

Hi
according to the Apple specs for the 1.83GHz mbp's - 2Gig of memory is the limit......
512MB (single SODIMM) of PC2-5300 (667MHz) DDR2 memory on 1.83GHz configuration; and 1GB (single SODIMM) on 2.0GHz configuration; two SODIMM slots support up to 2GB
Crucial Memory says the same.

Is the apple laptop with 4gb ram and i5 better than other laptop with 6gb ram and i5

is the apple laptop with 4gb ram and i5 better than other laptop with 6gb ram and i5

Well it depends on the age. http://www.everymac.com/ should help you identify the age of the two models.
Apple may use two processors called i5, but newer models have different optimizations than older models.
The processor is usually not the main affect on speed. RAM helps, but barely unless everything is on an SSD already. Hard drive speed is usually the limiting factor of speed on computers. eSATA hard drives with higher RPM can often yield the fastest results because notebook hard drives tend to be slower that are not SSD, but for those you need either Express/34 or Thunderbolt based adapters.

ThinkCentre M93p not booting with WD MyBook USB 3.0 drive

Hi!
I have a serious problem as boot freezes on my ThinkCentre M93p Tower at the Lenovo logo when the Western Digital MyBook USB 3.0 drive is attached at boot time. I have already commented on this in this thread:
http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T420-Not-booting-with-3TB-external-USB3-dri...
It seems to be an UEFI / BIOS problem and I hope that there will be a resolution soon, as I like the Lenovo ThinkCentres and would like to buy more for our company. This problem seems to be present on Lenovo notebooks and desktops when looking at other posts here.
Regards,
Anguel

Have you actually opened a support ticket with Lenovo?
I had a problem with my M93p SFF relating to an older external USB drive from Seagate, and an apparent incompatibility with management of the drive across soft reboots. I opened a support ticket and got superb results from Lenovo engineering over the next few months. I sent them the drive to have (as I had no use for it, replacing it with a new Verbatim USB drive which was fully 100% compatible with the machine and saw none of the problems I saw with the Seagate drive).
The eventual outcome was a public fix in a new version of the BIOS to handle the unique characteristics of the Seagate drive.
So, have you actually opened a ticket with Lenovo? They need to have something official to start from when new problems are discovered. The M93 machines are "new", so issues of compatibility is not a surprise to me. Especially when UEFI, GPT, large drives >2GB, and Windows 8 are concerned.
[I'm still staying with Win7 Pro x64 for now.]

How can I have multiple WINDOWS (NOT tabs) with INDEPENDENT content?

How can I have multiple '''windows''' (''not ''tabs) with '''independent''' content?
I used to be able to open separate windows with Firefox, and the content could be completely different in each window. No matter what I did in any window, no OTHER window open at the time, nor any of the content therein, was affected. This is no longer the case and it is extremely frustrating for me.
I do ''not ''like tabs and do not use them. I prefer multiple windows plus I am so used to using them, for so many years now! But with v9.0.1 I suddenly can no longer do what I've always done with my browser without this aggravating problem constantly reminding me that I can't have what I want in firefox anymore.
Or can I? Does anyone have a solution I don't realize exists?
Thanks,
Sowelu

AppleScriptObjC can use pretty much everything in the Cocoa API, so yes, it is possible.
Note that a view is not the same as a window, and a window can have multiple views. There are also many ways to implement "tabs"; take a look at some of Apple's applications - they use various mixtures of toolbars, checkboxes, and radio buttons, for example. An application such as this will be a lot more involved than what you have done so far though, using custom classes and subclassing existing ones, so be prepared to do a lot of reading and researching.
