The dv6700z And dv9700z WILL Support Over 4gb of RAM

I've asked on these and other forums if my dv6700z and dv9700z laptops would support over 4gb of RAM and I was told absolutely not. The hard limit on these motherboards is set at 4gb. Period. Even the memory manufacturers told me the 4gb limit was cast in stone. I could forget about squeezing a few more years from my laptops with life-giving RAM upgrades.
Well, I pleased to announce that these laptops absolutely WILL support over 4gb when running under a 64-bit operating system. I have just installed a Patriot 4gb PC2-6400 memory module carrying p/n PSD24G8002S from NewEgg, along with one existing 2gb module. The machines all booted and addressed 6gb quite nicely, thank you. Now, I barely even notice hard drive activity since the upgrade. 64-bit Windows Vista, Windows 7 and Ubuntu 10.10 Linux all work flawlessly with over 4gb.
Now that my little experiment has worked, I am going back to NewEgg to slug a full 8gb (4gb x 2) of PC2-6400 memory in all my dv6000 and dv9000 laptops. I can highly recommend this life-extending feature to anyone running 64-bit operating systems.
By the way, NewEgg pictures these modules with 4 chips per side, but they have 8 chips per side. $70 each and free shipping. 200 pin DDR2 RAM is expensive, but probably not getting any cheaper.

Hi:
I just bought the same module for my HP Elitebook 6930p. I only bought one to make sure it would work (I have always bought Crucial memory in the past) but when I saw the price of a Crucial module compared to the Patriot module, I couldn't resist. I bought the Patriot module based on the many excellent reviews.
My module came yesterday and works great! So, I ordered another one last night and can't wait to max out the memory in this notebook to 8 gigs!.
Even at 6 GB, this thing flies! My WEI dropped .2 of a point from 5.9 to 5.7 but I am sure this is due to not having matched pairs as this notebook supports DDR mode.
I will run the WEI tool again after installing the matching 4 GB module and expect the index to go up again to at least where it was.

HT3231 I am migrating about 450GB from my MacBook White to my MacBook Pro, wirelessly and it will take over three days, having spent 18 hours on the first 15%. Is it possible to interrupt this migation without damaging either source or target?

I am migrating about 450GB from my MacBook White to my MacBook Pro, wirelessly and it will take over three days, having spent 18 hours on the first 15%. Is it possible to interrupt this migation without damaging either source or target?
On reflection I should have used a wired connection or migrated at a later time but is it possible to interrupt the process now and rerun with a wired solution without damaging either laptop?

I have two iTunes libraries - about 172GB that I keep on my MacBook Pro and 500GB+ that I keep on an external drive. If you wanted to do something similar - keeping that precious internal space to a minimum - you can just create two libraries and hold down the option key when opening iTunes: this allows you to select which library you want to open.
Just a thought...

Attempting to update software and the process says it will take over 600 hrs. Why?

I am attempting to install available updates (4 total). My system says it updating Safari and it will take over 600 hrs. Can anyone help with a suggestion?

The time to install may change after a few minutes to something more reasonable. BTW, I don't think it's ever a good idea to install a number of updates together, especially, but not only, if any restarts are involved. I would run them one at a time, making certain each one has been installed successfully. Or, get them separately from Apple Downloads and install from the Desktop.

My iPad is locked up and has a apple and a bar under on the screan and it will not turn on or off. Anyone know how to solve this problem?

Press and hold the Sleep/Wake button until the red slider appears. When the red slider appears, release the Sleep/Wake button.
Instead of dragging the red slider, press and hold the Home button for six seconds.

I am purchasing a laptop with a 4k screen (3200x1800) resolution, will Lightroom work at these levels? what is the highest resolution LR will support?

As Rob has pointed out there is no maximum resolution that LR supports, but performance decreases as resolution increases. I'm using an i7-860 quad core system with a 1920 x1080 (2.1 Megapixel) monitor and LR runs well. A 3200 x1800 (5.8 Megapixel) monitor will require ~2.75 x more processing to render the real-time loupe image in the Develop module. Some people have reported sluggish screen updating when making adjustments in the Develop module with even lower resolution monitors such as 2560x1440. Here's a post that discusses the issue:

How to upload words, exel, PDF file from the pc via itune to the iPad, and where will the uploaded file be saved? In the apps?

You will need an app (or apps) on your iPad that is capable of reading the documents, as they will be saved with the app - if you don't have such an app then there is nothing to transfer them to or to read/access them.
One method of transferring them is toconnect your iPad to your computer's iTunes, select it's app tab, and then scroll to the bottom of it - you should the apps That you've got that are capable of file-sharing (if you've got any). Selecting/high-lighting one of them should then allow you to add files to it via the box to the right of it.
An alternative way to get the documents onto your iPad is if the app that you want to transfer them to has a wifi setting, which will then allow you to transfer the documents wirelessly. You can also send the documents to yourself as attachments and then use Mail's 'open in' facility to copy them into your chosen app.
Edit : more info on file sharing from the manual :
File Sharing lets you transfer files between iPad and your computer. You can share files created with a compatible app and saved in a supported format.
Apps that support file sharing appear in the File Sharing Apps list in iTunes. For each app, the Files list shows the documents that are on iPad. See the app’s documentation for how it shares files; not all apps support this feature.
Connect iPad to your computer.
In iTunes, select iPad in the Devices list, then click Apps at the top of the screen.
In the File Sharing section, select an app from the list on the left.
On the right, select the file you want to transfer, then click “Save to” and choose a destination on your computer.
Transfer a file from your computer to iPad:
Connect iPad to your computer.
In iTunes, select iPad in the Devices list, then click Apps at the top of the screen.
In the File Sharing section, click Add.
Select a file, then click Choose (Mac) or OK (PC).
The file is transferred to your device and can be opened using an app that supports that file type. To transfer more than one file, select each additional file.
Delete a file from iPad: Select the file in the Files list, then tap Delete.

5.3.1 is the final version that will support...

Hello -
I am very upset to discover that Cisco will no longer be supporting new software releases beyond 5.3.1 on the hardware that is widely deployed in my environment, including the core which is a pair of 7371 at 2 datacenter locations. Can anyone confirm if this is correct? Why would the WAVE-574/674 that just came out maybe 4-5 years ago not support anything beyond 5.3.1? What about version 6 coming out next year? What does this say about the future for WAAS?
Cisco WAAS, Release 5.3.1 is the final version that will support the WAE-674, WAE-7341, WAE-7371, WAVE-274, WAVE-474, and WAVE-574 platforms.
http://www.cisco.com/en/US/docs/app_ntwk_services/waas/waas/v531/release/notes/ws531xrn.html#wp63349
The last day of hardware support is not until August 31, 2017. So am I supposed to be stuck on 5.3.1 for the next 4 years and not take advantage of any new feature sets in the upcoming major releases? It's not like the WAVE series doesn't have enough CPU/memory to handle thew newer versions. I know the 7371 comes with plenty of juice to be able to support any new features you throw at it.
http://www.cisco.com/en/US/prod/collateral/contnetw/ps5680/ps6474/eol_c51-700260.html

The WAE 274/474/574/674/7341/7371 all reached End of Sale in August 2012. WAAS release 5.3.x is the final release which will support these now end of sale platforms. The announcement for WAAS release 5.3.x in the release notes as being the final release supporting these now end of sale platforms is to assist customers in proper migration and software upgrade planning.
Cisco has provided major feature functionality well after the end of sale for the WAE 274/474/574/674/7341/7371 in August 2012, for example WAAS release 5.1 in December 2012 and release 5.2 in June 2013 were released well after the end of sale and provided new major features and functionality for the now end of sale WAE 274/474/574/674/7341/ 7371.
These end of sale platforms will continue to be supported in the WAAS release 5.3.x maintenance release-train cycle which will continue with software maintenance releases in accordance with standard Cisco policy for software end of sale. Software maintenance releases will continue in the WAAS release 5.3.x until the end of sale for WAAS release 5.3.x is announced and the end of sale milestone is reached at a later date and the now end of sale platforms will continue to be supported with release 5.3.x as needed.
This is NOT an announcement of stopping support for these now end of sale platforms and these platforms will continue to be supported in release 5.3.x. At a later date the end of sale/support for release 5.3.x will be considered/announced and after the first year after the end of sale for release 5.3.x we will provide bug fixes, maintenance releases, workarounds or patches for a period of 4 years in accordance with standard Cisco end of sale policy.

The iphoto and itunes will not open please help

on my Mac G5 the iphoto and itunes will not open can anyone help

Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at the top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
Then, hold the Option key down when trying to open iPhoto, does it ask where it's Library is? Or what exactly happens?

If you are having the same problem, i.e. a disk permission problem, open your favorite search engine and search on, "change disk permissions", and I think you'll find plenty of information on how to fix the problem. This is a Lightroom forum. Your problem is with your operating system. There is no sense in rewriting instructions that are already available if you do a simple search.

Have a problem where I'll occasionally shift my computer (i.e. physically move it, say from the coffee table to my lap on the couch) and it will freeze and the screen will turn into a bunch of horizontal multicolored lines (closer to 100 lines than 5). Usually restarting (by holding the power button to turn it off) works. A few times that has resulted in the three beeps (RAM issue? -- I've since replaced my RAM [it *seemed* to stop it for a while, but maybe not]), but the second time it always works. Attempting to SSH into the computer during this state does not work. Please advise as to what to do/what reports I can run and post. I will take a pic next time it happens.
Here's this info:

Sounds like a problem with your GPU. Do you have an external display you could connect your machine to in order to test this? If the external display renders the same way, then your GPU is damaged. If the external renders fine, then the CPU display is damaged.

The dv6700z And dv9700z WILL Support Over 4gb of RAM
