Single NVIDIA 7300 GT...how would it handle dual 20' Dells?

I'm a student film editor...just wondering how well my single NVIDIA 7300 card in my MacPro would handle dual 20' Dell Widescreens. I have one, but I feel like I need a second one...but I don't think I want the second one if it means that I really ought to upgrade my graphics card as well. Any advice?
Mac Pro Mac OS X (10.4.8)

they will improve the speed of the graphics fitting 2 7300 GT's
This is a pile of bollocks. Adding a 2nd Nvidia 7300 GT will only give additional display support and will make no difference to your GPU processing abilities. SLI is not supported under Mac OS X.

How Would You Handle Carridge Returns & Line Feeds in A Spreadsheet file.

I have susessfully created a logging program which creates a spreadsheet file. I have additional information added after the loggging data is complete which I have seperated it by a CR/LF. How can I display this particular part of the file only?
I have attached the file in question, "DATA15.dat".
Attachments:
DATA15.dat ‏1 KB

Read the file like you normally do (2 D array (from Spread sheet file) )
Then scan the first column for the CR/LF character and find the index of it (may want to use serach 1D array for the collumn).
Then Divide the array into 2 diffrenet arrays, 1 above the found index (containg data to display), and the other one to ignore, or simply use "array subset" function

HT5219 How would I connect dual monitors and also a firewire cable? Macbook Pro (Retina)

Currently I am using two thunderbolt to DVI connectors for the dual monitors, but I am left without any firewire cable connection for my audio interface. THe only adaptor I found was another thunderbolt to firewire, but since I already used these two ports, I am left with no options. I haven't been able to find any usb to firewire cable connections.
Are there any other adapators/ports I can use that I am not aware of?

Late 2006, 24" iMac, 2.16 GHz Intel Core 2 Duo, Screen Tearing, nVidia 7300

Late 2006, 24" iMac, 2.16 GHz Intel Core 2 Duo, Screen Tearing, nVidia GeForce 7300 GT
I've been suffering with screen tearing, strange screen artifacts, etc. followed by totally unresponsive freezing machine. This problem has been happening to varying degrees for about 9 months.
Initially, I was able to mitigate the problem with smcFanControl. Adjusting the fan speeds up helped keep the machine cool and prevent most of the problems. Recently, we had a spell of hot weather and the fans just couldn't keep up. If you're using smcFanControl, the only fan speed that will really make a difference is the CPU. The HDD and ODD fans are no where near where you need to be.
Also, I noticed the machine was LOADED with dust when I took it apart, including the heat sink fins for the graphics card. If you have time you may want to try a thorough cleaning with compressed air before replacing the card. You just need to get through step 11 below to access what needs to be cleaned.
Based on reading here and elsewhere, I decided to replace the graphics card. To give back to the community, I wanted to layout the procedure here.
Where to buy the card.
I had a tough time finding the right card. I did exhaustive web searches using every combination of Nvidia 7300 GT, etc. You really need to search by the Apple part number. The Apple part number for the 7300 is 661-4179, for the 7600 is 661-4180. I found it at We Love Macs and at dv warehouse. I paid $248 for the 7600 card. BE CAREFUL buying a "refurbished" card. At We Love Macs, "refurbished" means "pulled from a working machine." Could be a machine with as much mileage as yours and prone to the same failures as yours.
The card is an MXM style card (generally used in laptops), with a giant heat sink and heat pipe assembly. The card can be separated from the heat assembly. If I had time, I would have tried a generic, cheaper, MXM style card.
Dispelling some myths.
People here and elsewhere have said that no Intel iMac graphics card can be replaced, that they're wedded to the logic board. The one on this model can be replaced, I've done it. Also, some have said you can't put a 256MB, 7600 GT in a machine that originally had a 128MB, 7300 GT. Also, not true. That's what I did to my machine and it is working fine.
So here's the step-by-step on my take apart and replacement. This is just one user helping out others, PROCEED AT YOUR OWN RISK. This takes about 1 1/2 hours to take apart and 2 to put back together.
1) Install the iStat widget and monitor the temperatures for a few days and record the temperatures (to be able to verify that you've completed the repair correctly later)
2) Make a complete backup of any internal drives and make sure the backup will be bootable (use Carbon Copy Cloner)
3) Use static safeguards, like an anti-static wrist strap.
4) Get a pen a stack of paper envelopes to separate and label the pieces you remove.
5) You'll need a #2 Phillips and #6, 8, 10 Torx. Most of the screws at T-8. There are 8 T-8s holding in the LCD. They are about 1 1/4" down. You'll need a long, skinny T-8 to get to them.
6) Unplug the machine and place it on it's back on a large white sheet of paper.
7) Remove RAM door, #2 Phillips x 2.
8) Remove RAM.
9) Remove 4 T-8s along bottom.
10) Remove large rectangular plastic bezel surrounding the whole machine, tilt up being careful not to stress iSight cables. You'll need to stretch it around the RAM ejection tabs.
11) Detach two iSight cables.
12) Peel up black stickers at lower corners of speakers.
13) Remove LCD screws, T-8 x 8. You'll probably drop a few, they're pretty easy to retrieve.
14) Remove two retaining screws on right hand LCD cable. T-6 x2 Unplug cable.
15) Remove LCD inverter cable, left.
Start unplugging everything connected to the logic board.
16) Unplug cable coming from right speaker. Note cable routing, it is the only one that's a little tricky. Also, note that the left one plugs in on the right and the right one plugs in on the left.
17) Remove right speaker. T-10 Note: left and right speaker screws are different lengths.
18) Unplug ODD blower cable.
19) Unplug ODD temp cable and lift up tape.
20) Unplug HDD blower cable.
21) Unplug the HDD temp cable.
22) Unplug the camera & mic cable.
23) Unscrew the clamp securing the airport card (has two antenna cables going to it, labeled PCIE), T-6 x 2
24) Unplug SATA cable.
25) Unplug Power cable, thick black plastic harness, socket.
26) Unplug ambient temp cable.
27) Unscrew the bluetooth card, T-6 x2.
28) Unplug CPU blower cable.
29) Unplug power button cable, 2 conductor, tiny cable, bottom left.
30) Unscrew left speaker, T-10, unplug from logic board, but just leave dangling, no need to remove cable completely.
31) Remove logic board screws. Be careful to segregate them, they have different lengths and different thread pitches and thread types. Some are machine threads going into metal, some are coarse threads going into plastic.
31a) Heat sink frame to case T-8 x 2
31b) Logic board to case T-8 x 3
31c) Screws at heat sink from arrows T-8 x 3
31d) Logic board at bottom near RAM slot T-8 x 2
32) Unplug ODD ribbon cable, be extremely careful. Release plastic tabs on each side to remove. Be sure it is fully and evenly seated when you put it back later.
33) Remove logic board with attached graphics card.
34) Unplug graphics card heat sink sensor cable at logic board end.
35) Remove graphics card screws 2 x T-6
36) Remove single screw from small L-bracket on heat sink 1 x T-6
Replace graphics card.
Reverse steps, put everything back together. Be careful not to pinch any cables when you put the logic board back in. When you put the LCD back in, if you can't get the screws to stick to the driver, use some glue stick from your kid's art supplies.
Test everything. You've disconnected every cable in the system.
I torture tested the machine with a space heater on it, 5 different videos of different formats playing at the same time. No problems.
I took a lot of pictures inside the machine. As soon as I figure out a good place to post them, I'll try to add a link here.
Good luck

Greetings!
I know this is in response to your post from over 2 years ago, but I was searching on Apple's site for the max RAM I can upgrade our refurbed iMac too and it brought up this post.
Oddly enough, I've been experiencing the same screen issues and locking up on our iMac as well. I was concerned it was a bad memory module, but now I'm thinking it's the same issue you found.
Because I bought this some 2+ years ago refurbed from Apple, I'm not surprised that could be the actual problem.
I've pulled this thing apart once to replace the hard-drive which crashed about a year ago, so I'm not totally new at opening it up, but this process you mention sounds pretty intense...just wanted to get your second take on it based on what I've done thus far.
Thanks again for posting this...it was an eye-opener as to what might actually be causing our issues with our trusted Mac!

How do we handle a item in both as a select list & text

Hi All,
In my application, i have used Create button..when ever a create button is clicked a "Select List" will apper..
Similarly i have also a "Edit" icon when ever a icon is clicked it will also the same "select list item"...
Now the end user is asking to make the select list item as redaonly when we clik on Edit icon...
How to handle this scenerio..
The way i have done is as of now is that i have created two items with the same name one is for select list &
the other is for the text item using conditional i have managed..
But i would like to know is there any other way with out creating any extra item & by using only the select lits item can we achieve it or not.
Thanks,
Anoo..

Hi Anoo,
You mentioned in your original post that you have a select list item and a text item, and that you're using a condition to determine which one to show. For the Read Only condition for a single select list item, you would specify the condition you currently have that is telling ApEx to show the text item rather than the select list.
The idea here is that if the Read Only condition evaluates to TRUE (currently in edit mode), then the select list item will render as read-only; if it evaluates to FALSE (currently in create mode), it will render as a normal select list.
Hope this helps,
John

CUDA-OPEN CL IS ENABLED - How would I know?

After backing up my working OS, I attempted to try latestSG updates with Mavericks.
I know, what was I thinking...?
Mac Pro Early 2009
32 Gigs Ram
CUDA Version 5.5.28
Nvidia GTX 285
Mavericks
SGworks ok with native SG - LUTs and masks dont kill playback. Lots of caching.
Is it using open CL?
THE QUESTION: HOW WOULD I KNOW IF IT IS?
How can we check if GPU is being ultilised? Unlike all AE,PP, ME and proper adobe apps, SG doesnt give me any indication of whats going on. This is rubbish.
If I grade same clip via Direct link plays back at one fame per second..
Sending a DL'ed grade back to premiere give me no image, just a 'Media Pending Link' - unless I turn off the embedded Lumetri effect.
Could anyone tell me what CUDA drivers I might roll back to to get this working?
I mean, it was tested with a specific set of 'current' drivers, right?
sidenote: After Effects CC also refuses to utilise this card, which is plenty fast for most things.

Same test with Mountain Lion
Mac Pro Early 2009
32 Gigs Ram
CUDA Version 5.5.28
Nvidia GTX 285
Using CUDA in PP, playback was leagues better than Open CL. But still crappy with any sort of mask in play.
Using Direct Link within Speedgrade with Single Primary layer is great.... but utterly unusuable if you add masks. (who does that eh?)
Even if you add empty grading/adjustment layers playback also nosedives, so the hope I had of isolating my masks on separate adjustment layers doesnt help, as it makes working in SG terrible.
You cant really crossfade multiple SG adjustment layers in PP, as the vignettes need to be the same group as the grade for the transition to act it properly (or nested, but that's not the point of this workflow).
When you talk about using Nvidia Cuda GPU accelaration not being available for Speedgrade, how does impact on it's use along the whole pipeline? You need to be clear about where Cuda/CL impacts on performace, and not waste everyone's time discovering the grizzly truth. How many posts are reporting the same problems, again and again.
What if you are outputting your graded edit in Premiere to AME (which also has CUDA/CL options? If I render SG graded edits in AME from Premiere - using Open CL adds about 50% to the rendering times.
Despite having 32gigs of available ram, SG insists on caching to disk - why?
Admit that the performace using masks is Direct Mode is not ready for production, and stop trying to pretend it is.
Update the information links on this forum, as many are out of date, or point to previous versions.

How do you handle multiple at the same address?

My wife just got an iMac. She is using the Birthday feature in Address Book and iCal to track our friends and family birthdays and anniversaries.
Question:
How do you track it when multiple people are at the same address? For instance, our friends are a family of four, but they all live at the same address. Do you need to make a separate Address Book card for each of them, even the 1 year old baby? Or can you track multiple people in a single card with custom fields?
If you do need to make multiple cards, then how do you handle mailing lists? For instance, if I make separate cards for all four of them, how do I make sure I only send on Christmas card when I use my Mac to print labels?
Thanks for any advice.

This is really an issue that you're going to have to resolve yourself since Apple's address book isn't really built with this in mind - darn it. For me there are three scenarios. First, a singleton. No problem. Second a family for which all members share the same information - acquantences to whom I don't send birthday greetings. These get one card and I'll put in both (or all) their names in the first name field (as in Bob and Jean). If there are children, in the last name field I'll add 'and Ken' or 'and the kids'. Third, a family for which some fields are different - perhaps cell phone number, birthday, etc.
For mailing purposes, I create a holiday group and put the people I'll be sending cards to into the group.

How does IITTrackCollection handle ItemByName if there are multiple tracks by the same name?

I am writing a program in C# that is trying to check if a track already exists in the iTunes Library before adding it (thus preventing duplicates). The best method I have come up to do this with is to use 'MyPlaylist.ItemByName(SongName)' to retrieve a possible duplicate and then compare the rest of that track's attributes (i.e. the artist and album). However, I have several examples of tracks in my library which have the exact same name, but are in fact completely different and unrelated. How is this handled by the iTunes COM? Or is there a better way to do it?

How best to handle multiple web sites using iWeb 08

I currently am using iWeb08. I am maintaining two websites; The church site resides on a Rogers server. I use Transmit as a FTP loader. The other site is an engineering society's website that is posted on Apple's server. I have an ME account just for the latter group. iWebsites is used to alternate between the two sites. The church group has a .ca web address.
Is it worth upgrading to iWeb 09? How does iWeb09 handle 2 websites? I wish I could publish both to the Mac account but have not figured out how. I must retain the rogers account for viewing the church site
Has anyone deleted iWebsites from OX10.5.6? How was it done? I know that backups are mandatory before attempting these changes.
Thanks,
Bill

In its current form, iWeb '09 doesn't handle publishing well at all!
I keep all my sites on separate domain files, each in their own folder. Any site is launched in iWeb by double clicking the domain file. I start each new site from a new, blank domain file.
I keep all my website folders in a folder in a second dock so that I can launch any site with two mouse clicks - faster than you can launch iWebsites!
You can publish as many sites as you want to one MobileMe account but you can only have domain name forwarded as Cname. Any more have to use masking with all its inherent problems.
I would be more inclined to dump MobileMe and publish both sites to a decent hosting company.
The new iWeb '09 FTP works for some. I have tested it with my server - Host Excellence - which doesn't force you to upload to a Public_html folder and this goes as planned.
Having said that, I still publish to a local folder as I optimize and upload my files using Web Site Maestro. Once you have published your site for the first time, this application will then use its Smart Handling feature to process the changed files only.
Unless all your viewers use Macs you have to optimize to get your pages to download in that browser that all the Fred Flintstones of the world use.

Is it possible to create a single texbox? and how to delete a button on a form? please asap, badly n

Is it possible to create a single texbox? and how to delete a button on a form? please asap, badly needed it right now. thx -regards gustavo

Hello Gustavo,
You can create a single textbox using the textbox option here (This is for you to enter text - not for the visitor): http://jingsite.businesscatalyst.com/jing/2013-09-30_2212.png
If you want to create a textbox for the visitors to enter text, then you need to enter a form, and you can delete the "message" field from the "simple contact" form, but not the name and the email fields (those are mandatory and can't be deleted).
You may want to check external forms in case you want to have the form rather customized, to check if you can have forms with single textbox. An example would be "Jotform".
Hope this helps.
Cheers

How can you handle Third Party Payment in Oracle Payroll

People I hope you all are at your Good Health!
I have a question and that is i would like to know how i can restrict a dependent from getting an Insurance benefit after he has crossed the Age =18 Also the To date must be calculated and populated automatically.
Also, how can we handle this third party payment in the Oracle Payroll.
All comments are welcomed.
Chetan

For the payment piece, create a payment method on the person record as a third party. you would need to have setup the recieving party as a third party organization before setting up at employee level.
During normal payroll processing, you may run Third party check writer to generate a check .
Ankur thank you for the response i have understood that we must create a Payment Method and Check the Check box for Third party Payment on Payment Method window.But how will that be handled for case where an employee has taken a Loan from a Bank and he has to be deducted every month from his salary how can we handle such a requiremet.
I did not understand when you said :
"you would need to have setup the recieving party as a third party organization before setting up at employee level.
During normal payroll processing, you may run Third party check writer to generate a check ."
Could you please explain me.
Regards,
Chetan

How SEM BCS handled balance carried forward?

Hi,
I would like to find out how SEM BCS handled balance carried forward?
Income statement
Profit after Tax - 50
Balance Sheet
Retained profit (last year) - 100
Current Year profit - 50
How do i configurate 'Profit after Tax' = 'Current Year profit' in workbench? Is BCS going to store the computed results?
Balance items (ie 'Retained profit (last year)' and 'Current Year profit') by default are carry forward to next year in BCS.
Do i need to configurate 'Current Year profit' add to 'Retained profit (last year)'?
Pls advise.
Thanks.
Regards, Renee

Hi Renee,
By default, the balance sheet items are to be carried forward to next year. If you dont make any settings, both items, Retained profit (last year) and Current Year profit will be transferred to themselves, that is not correct.
You need to show the system which items are to be carried forward not to themselves.
To force the system to make the proper transfer, in UCWB go to Consolidation Functions -> Balance Carryforward -> Items to be Carried Forward.
Enter there the following information:
<b>Orig. Item__________Debit Item_______Credit Item</b>
Current Year profit____RE (last year)_____RE (last year)
Do the similar operation for all items to be carried to other than themselves items, for example dividends of the current and last years etc.
Hope this helps.

How can I handle exception? - to give user more friendly notification

Hi!
User gets an error:
'Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. current checksum =...'
How can I handle this exception (when two users want to modify the same set of data at the same time)? I would like to hide the above error message and give user more friendly notification.
Thanks in advance,
Tom

Thanks Vikas for your answer.
These workarounds are really creative and I want to use one of them. BUT my problem is to 'catch' the exception/error when two users want to modify the same set of data at the same time.
Those solutions which we can read about in this link you gave me describe handling exceptions in pl/sql processes. How can I catch the error I am talking about in pl/sql code?
Code would be like this:
DECLARE
two_users EXCEPTION;
BEGIN
IF --catch the error
THEN RAISE two_users;
END IF;
EXCEPTION WHEN two_users
THEN :HIDDEN_ITEM := 'Error Message';
END;
What should I put in a place where there is '--catch the error' ??
Thanks in advance,
Tom
