Z400: "lost in the past..." I need guidelines Ram upgrade on a Z400
How many Ram Win 7 can recognize and use in a Z400 Quad core?
I just bought a Refurb factory because I have a legacy PC running 32-bit software. I used 4 GB of Ram in my previous core Dual 2 under Vista Ultimate and it was ok, but I want max processing power for video rendering with a bit more robust Ram memory. Looking around, there seems to be a split between people saying Win 7 can only recognize and use a maximum of 4 GB, which I find hard to believe. I also hear his depends on how many channels, you're behind the wheel and I think it is 3. It is the Quad 2.66 GHz configuration with 6 locations and I think 4 in use, and I think that the claim is that it can hold up to 16 GB, but I am confused about how this is done.
According to the HP website, it seems that it will be an Intel Xeon W3520, 2.66 GHz, 4 MB cache, 1066 MHz memory, 4.8GT / s QPI, Quad-Core. Then, they advise the following:
DIMMs must be distributed across all channels memory three for best performance. Each processor supports up to 3 channels of memory DDR3. In order to achieve a return at least maximum 1 DIMM must be inserted in each channel. To get full support 6-channel, 2 transformers MUST be installed.
I don't understand this. I also do not understand if I can mix the memory sizes in the slots and remain evenly distributed and stable. I'll have to see if it comes with a 1Gx4 or 2Gx2. If I have a minimum of 2 open unused slots and I want to go back up to 8-16 GB of DIMM3s, and if it is still useful, should I start with 2 x 4 or 4 x 2, 6 x 2 or 4 x 4?
Hello:
Limitations of memory in 32-bit and 64-bit operating systems are mathematical.
This article can explain how it works better than I.
http://www.ZDNet.com/article/clearing-up-the-3264-bit-memory-limit-confusion/
However, different versions of Windows have memory limitations as set forth in the list below.
https://msdn.Microsoft.com/en-us/library/Windows/desktop/aa366778 (v = vs. 85) .aspx
Bottom line... If you want to run more than 4 GB of physical memory, you must run a 64-bit operating system.

First of all, Hello to everyone.
Sorry if this is off-topic.

I downloaded two applications: (Invaders from space and RFM Anote far) and (over a month) this apps have the same status of project.
Some Android developers, tell me who have received an email from RIM with instructions and access to the promotion. I don't have this e-mail.
It is normal that the State of my applications does not (project) with more to wait a month?
I lost my PlayBook due to... not now why?

My app had the status of project when I first created the name information and metadata of the app on the supplier portal...
After this step, once I downloaded my file bar in the bundle file and submitted it, and then the status changes to waiting and then waiting on the test laboratory.
Having said that, you create a package file for the version and download the corresponding bar file?

N7010 hangs at the end of 8 gb RAM upgrade
I have a laptop Inspiron N7010 (about 3 years) which came with 4 GB of RAM. I want to move to 8 GB. I have tried 3 different brands of memory
including memory Dell. I ran the test expanded memory (memory Dell does not miss). I have the exact memory Dell support number
gave me. In all cases, after installing 8 GB of RAM, the start-up of the laptop, then at some point will just shutdown (power off, just like you).
The system information of the Panel shows that all 8 GB is recognized.
I searched and installed all of the bios, chip and updates of dell.
Does anyone have an idea why this is happening?
My problem is solved. I'm now 8 GB (4 GB + 4 GB) of RAM work in my Inspiron N7010. I carefully tested and used in the course of a day, so I am sure that it works. Knowing that my FSB running at 1 066 MHz, I made sure I ordered the memory which was held also at the same speed. I am glad that I did, as Tom Heafey, who appears in this thread there is three years.
I ordered two archmemory.com AM85180 memory cards in St. Louis. Each of them is a 4 GB, 1066 MHz, DDR3-1066 PC3-8500, 1.5 V, card memory 204 pins SODIMM. It wasn't first recommendation Ark of memory, but I insisted on 1066 MHz memory. They can now change their memory recommended on their Web page for the Inspiron N7010, based on this experience.
There may be other memory cards that can operate at multiple speeds that could run on this computer, but it is a proposal for a chance to try to find them. Sellers of memory seem to have no idea of what works in this case! On the other hand, these memory cards are optimized for this computer. As a result, they have worked the first time.

Hi, the trackpad batteries are unloaded much faster than in the past. I reload and replace them and they quickly weaken. What needs to be replaced, the batteries or the charger. Tried to look on the apple website to purchase and find nothing (there must be there somewhere). Thank you.
They may well be replaced. Take a look at this document. iFixit are well known in these columns.
If you always to 10.5.6? Otherwise, it may be a good idea to update your profile; It's still worth anyone when they answer your questions.

In the past 3 months I lost my computer such as automatic log-ins parameters and settings in outllook such as "empty my messages deleted at the exit." I checked my cookies and settings for them and that they are correctly defined if that is the cause. I'm frustrated to have to manually delete my files deleted before existing outlook and have to connect whenever I do my Bank. Strange thing is that it does keep my sign-in to facebook so why some and not all? Is it a hardware problem or software. I've had this computer for about 1.5 years. It is also a touchscreen working SOMETIMES but not always. Looks like a variety of frustrations come all of a sudden. If you can provide suggestions on how to "solve" these problems, I would really appreciate it.
