Is 2x 512 MB sticks better than 1x 256MB and 1x 1GB stick?

Its what the title says, the reason I say this is because I am trying to be very cost effective but get the best performance possible for the price. So is 1 GBs of RAM with even amounts better than 1.2 GBS with non-equal amounts of RAM?
Also, another RAM question - When I do replace the RAM, does it matter which stick I take out of the MacBook?

Depends. If your intent is to get to 2GB then yes, going to 1.25GB is better. Otherwise, performance-wise I think going to 1GB in 2 x 512MB a matched pair would be nicer.
The difference in Xbench tests seem to be around 5%.

Are Classes better than Function groups and Modules

Hi,
Are classes better than Function groups? For example if you want to execute something is back ground or use parallel processing you can't do it using classes. Even inside classes most of the places we use Function modules.
Then how classes are beneficial?
Regards,
Deepak Bhalla

Yes they are compared in the sense that the class and function group are the containers, and the methods and function modules are the interfaces in which you interact with the encapsulated data.
Again if you are developing an application in which you are not forced to push the processing to differenet work processes, then using classes/methods is preferrable. The reason I say this, is because anything coming from SAP will most likely be implemented as a class as opposed to a function group. This is not to say that SAP will not create new function modules, because of course there still is a use for them.

Build and format better than to build and burn?

I'm going to be burning 15 copies of 2 different single layer dvds through DVDStudioPro. I've tested both discs in this project and they're ok to burn.
Reading through my reference material, I don't get a clear sense of what to do next. Should I build and format and store the resulting disc image (.img) to somehow burn from in DVDSP?
Or should I just "build" each project and then format and burn the 15 discs one by one?
Thanks in advance

Hi..
I just build the project which will creat a TS folder wherever you select and render all the menus etc.
The when you want another copy then just "format" a disk. (i.e. burn the info to a disk)
You could build a disk image and burn a disk image that way.. but I don't think it will save you any time.

20 inch Intel iMac with 512 MB RAM: is an additional 512 or 1 gB stick bet

I have a stock 20 inch Intel iMac with 512 MB of RAM.
I've read that this computer uses dual channel RAM, so I am wondering whether an additional 512 MB of RAM or an unsymmetrical 1 GB RAM stick would be better?
Also, anyone know who makes the OEM 512 MB stick and where to get compatible memory for my iMac?

"anyone know who makes the OEM 512 MB stick and where to get compatible memory for my iMac?"
Regardless who made your OEM module, it will have a label with their name and the product specs (or at least a product number, which, on a page at their website, can be decoded for its exact specs).
Mine was made by the U.S. company Micron Technology at their Singapore factory, and the label states that the module is lead free. A similar Micron module can be purchased online from Micron's wholly owned subsidiary Crucial Technology, which is their retailing arm. Retail customers can not order directly from Micron, just as they can not order directly from either Samsung or Hynix, the other two large OEM RAM manufacturers.
"I am wondering whether an additional 512 MB of RAM or an unsymmetrical 1 GB RAM stick would be better?"
I agree that more RAM is better, will make it snappier, and prefer to buy my 1GB stick of RAM from Crucial, as I know it will be compatible for my Mac and its OEM stick (regardless of the maker) as long as I use their online Mac selector tool.

PP CS5/5.5 chroma key better than AE CS4?

Hi everyone.
I think I read somewhere a while back that the chroma key in PP CS5/5.5 is better than AE CS4's Keylight. In fact, the PP effect may be an improved Keylight , but I can't recall this for certain.
Can anyone verify this?
Thx.

I've keyed with the same camera for a couple of years now, and it's got a pretty narrow band in which greens are easily keyed. DVCPRO HD is not well-reputed for its handling of greens, or at least as a result of it's use with an older 1/3" sensor. I've gotten the best results with the exposure on the screen at about 50-60IRE, but that's just in my scenarios. Most of my material is recorded to P2 cards (though I did one long shoot with OnLo and a green screen), but the footage encoding is the same--it's all DVCPRO HD. I've got some stuff that I did recently that keyed like buttah with Ultra--I literally had a solid key in 20 seconds with just picking the background color and tweaking a couple parameters.
So, since "brightly lit" and "lower lit" are subjective terms, it's hard to give you any specific recommendations other than to try to stick in a particular exposure range. All I know is that when your green screen footage is evenly lit and at mid-range exposure, Ultra does a pretty good job with minimal effort.

Whether installing 64bit OS is better than 32bit in a 64 bit PC?

Hallo friends,
Now a days 64bit PCs are more common. But I think Operating systems and programs have not attained capacity to fully exploit the power of 64bit machines. (Of course Linux is better than MS counterparts in 64bit zone). If it is sensible to stick with 32bit for better experience in terms of stability and performance? What are the pros and cons of both methods? How we can attain maximum from 64bit PC? Since every one with a 64bit PC have tried both architectures, feed back opinions and suggestions in the above thread is anticipated from everyone.
Thanks to all

Is 1.3 Bios really better than 1.52B?? Neo2 Board and Some Observations!

Hi All... I read this post on the forums and it got me thinking and i did some fiddling and made some observations..
This is whith regard to the 1.3Bios being better than the 1.52B Bios.. because it would let you run in turbo mode...
Ok i've spent the last 60mins testing and i came up with the following..
1.3BIOS
With the 1.3Bios.. no matter what memory timings u set... it does'nt show in CPU-Z and it does'nt make a difference in the memory bandwith scores...
For example my ram was rated at 2.5-3-3-8 .. i changed it to 2.5-2-3-8 .. it did'nt change and my scores remained the same..
Going from Slow to Fast to Turbo.. did'nt incrase my scores.. actually.. donno how.. but i got a decrease in scores..
The only thing that was noticable was that MSI core-center overclocks the CPU a lil more than what is set in BIOS..
1.52B BIOS
With the 1.52B Bios... u can change the memory timings and it does show in CPU-Z and it makes a massive difference with Sisoft sandra.. 250mbps more..
What u set in the bios .. u get with the 1.52B.. Corecenter does'nt mess around and overclock it more..
Going from Slow to Turbo did give me an increase in scores.. slightly..
Im now running Ultra-Turbo.. and i get a sisoft bandwith score of 5250Mbps at 3.21G..
CONCLUSION
So infact i think the 1.52B is better than the 1.3 . I don't have a Radeon so i donno how these bios's work with the cards cause i've read about some problems... I'm getting one soon so 'ill post some info about that in a fortnight..
I personally think this board is great.. atleast the one i have.. never had a problem.. had it for 3 months.. i have a revision 1.. no DOT sticker.. and just the Neo2-S version... I've used Spectec 333 on this board too (dual) had no problems..
Wish i had some DDR-500 so i could test whether this board can do 1:1 above 250...whether it has a 1:1 limitation above 285 like some other boards.. that is my only doubt.. anywayz.. i hope atleast some of u are sailing as smoothly with this board as i have..
Get some nice ram .. this Twinmos Dual channel kit DDR400 with the Twinmos chips are really great.. and i recommend it..

That´s wrong. RAM-Settings are displayed fine. Turbo does make a BIG difference in scores. About 15% more performance. In Games and in benchmarks like 3dmark and sandra, too.

Apple TV - any better than an ipod?

Before I went and got an apple tv I decided to hook up my ipod video to the tv and see what the quality was like. So I ran svideo from a dock into my 32" sony lcd. It actually looked rather good for standard def programs (ie all itunes material). The Daily Show looked just fine and even The Office and The Riches playing letterboxed widescreen looked fine even when I zoomed the letterbox full screen with the tv.
I'm sticking with the ipod for now. Wondering if someone with the apple tv would like to try a comparison.

Wondering if someone with the apple tv would like to try a comparison.I find that the same file played from TV looks visibly better than when played directly from the iPod. HDTV scalers vary so results may vary with the quality of your particular HDTV/EDTV model. However, it would seem the TV is specifically enhanced for playback of such files and, in general, does a better than average job of scaling here.

Is the Mountain Lion so much better than the Snow Leopard that make it worth buying?

Is the Mountain Lion so much better than the Snow Leopard that I'm currently using and worth the money to buy it? Is it more or less confusing to operate?

OS X 10.7-18.0+ will NOT run any current PPC based programs your running.
http://roaringapps.com/apps:table
If you have a MacPro like your signature says (the tower, not the laptop) then it's not going to have much of a performance loss as say the MacBook Pro's will.
Older, less powerful Mac's have performance losses with the newer OS X Lions, it might be best to stick with 10.6.8 on a older machine until it drops, then spend the money on all new software on a newer machine instead.
One guy was here today and had a 2007 Intel Core 2 Duo and it was struggling to run OS X Mountain Lion, Chrome and Photoshop.
It just didn't have the hardware horsepower for all that bloatware.
My advice if it's not a top end iMac or MacPro, then 2010 is the cut-off point, those 2010 machines and earlier are likely better off on 10.6.8 max.
It all depends upon one's perception of performance really.

E7 better than N900?

Time for a upgrade and the E7 looks like an updated version of the N900! So is it better than or should I stick to the N900?

I'd agree 100% with Fender, the two phones really only have the physical QWERTY in common, the OS is completely different ! I love my E7 and am enjoying Symbian^3, but you really need to try it yourself. The screen and keyboard are superb, but I would reccommend you try a Symbian^3 phone before you 'jump in' , doesn't really matter which one , as they all work in basically the same way. The E7 is a great piece of kit, but it wouldn't suite everyone, for example ,people with macro photography as a main priority in there life would really hate it ! For viewing media and the web it's great, just try before you buy

Upgrading RAM... 4 + 2 GB better than 2 + 2?

Hi,
I have a
MacBook Pro 2.26GHz Intel Core 2 Duo (13-inch DDR3) MB990LL/A Mid-2009
capable of holding 8 GB of RAM. Right now it only has 2 GB RAM, though I'm not sure if that is 1+1 or just one 2 GB if that makes sense. I don't particularly want to spend the money to get 4+4 for the full 8 GB, but I want more than 4 GB. I was planning on buying 4 GB of RAM and doing it myself along with the 2 GB of RAM I already have (obviously this only works if the 2 GB is in one cell (?)). My question is... because 6 GB of RAM would necessitate a mismatched pair, would it be better just to get 2 + 2 for 4 GB RAM total? Is having a matched pair more important for overall speed and efficiency, or is the sheer number more important?
Thanks!

In general, more RAM is better, and matched RAM is better than unmatched. So 4GB + 2GB is better than 2GB + 2GB, but 2GB + 2GB is better than 4GB + an empty slot.
However, in your case, if the RAM you have was the original RAM that shipped with the computer, then it is probably 1GB + 1GB. And while I don't know of any technical reasons you couldn't run 4GB + 1GB, I suspect that the size difference would be very inefficient. I've seen 2GB + 1GB before, and I have an older MBP with 4GB + 2GB right now....but if the size differential between the two slots is too great, I suspect the MMU will begin to behave unpleasantly.
So, either get a 2GB + 2GB pair and pay again later to upgrade, or fork out for a 4GB + 4GB pair. In any case, make sure the RAM is of the same kind (as per Kappy's instructions) and that both sticks are from the same manufacturer.
And, of course, it's possible I'm wrong and you do have 2GB + empty slot...you can always open it up and look.

No.

Why does a DVI or VGA look better than HDMI for 2nd Monitor

Why does a DVI or VGA connection for a program monitor look better than HDMI. I've tested this on several systems with CS5x and CS6. The full screen output from premiere definitely looks worse with HDMI.
I can often see visual differences with the Windows GUI as well, over sharpening of text and lines, harsh rendering of gradients. It looks like a VGA signal displayed on a television.
I've looked at the NVidia stetting and it appears to be set to 1920x1080 at 60hz either way, DVI or HDMI. On one Acer 20 inch monitor the was VGA, HDMI, Composite, Component, and Digital Tuner, but no DVI. The program monitor has always looked blah from the HDMI. So I recently switched the connection to a DVI to VGA adaptor, and now the video looks so much better.
Any thoughts or explanations?

Just because the monitors accept a 1080P signal doesn't mean their native resolution is 1920x1080. At 20 inch they very likely can scale that signal down to the native resolution of the panel which may be 1600 x 900 or another resolution that is 16 x 9 resolution. That scaling can be done by the GPU or firmware on the Monitor depending on the video driver options and the firmware options. That scaling is also the most common cause to text and icon blurriness you are talking about. As an example there are Pro monitors that accept a 4K signal but scale it down to 2.5K or 2K on the actual panel. You might try going into your video card settings such as Nvidia control panel and look for the scaling options. Select GPU scaling and see if the preview is better. If that doesn't work select no scaling and see if it's better if the monitor firmware handles the scaling.

Open DNS better than Comcast xfinity DNS?

Is OpenDNS better than using Comcast/xfinity's DNS? If yes, how do I switch over?
I go to into Airport Utility and enter in the 2 openDNS numbers, something like 222 and 220, but at the bottom of the page right now (because I am using Comcast's DNS) there's a web address something.comcast.net Do I need to change that info too? If so, what do I put in that field?
Thanks!

How did you add them?
If you are using a single computer: Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu, and in the box marked 'DNS Servers' add the following two numbers:
208.67.222.222
208.67.220.220
(You can also enter them if you click on Advanced and then DNS)
Sometimes reversing the order of the DNS numbers can be beneficial in cases where there is a long delay before web pages start to load, and then suddenly load at normal speed:
http://support.apple.com/kb/TS2296
If your computer is part of a network: please refer to this page: http://www.opendns.com/start/bestpractices/#yournetwork and follow the advice given.
(An explanation of why using Open DNS is both safe and a good idea can be read here: http://www.labnol.org/internet/tools/opendsn-what-is-opendns-why-required-2/2587 /
Open DNS also provides an anti-phishing feature: http://www.opendns.com/solutions/homenetwork/anti-phishing/ )
Wikipedia also has an interesting article about Open DNS:
