Colour banding in new MBP 17 Quad core I7

Hi there has anyone had this problem yet.
I have a new MBP 17 Quad core I7 with an anti glare screen.
When I look at images where there is any colour or tonal graduation I get a coloured banding effect where the graduation starts....almost like a halo, like the screen quality is set on very low resolution...only it's not. The same images on my old MBP 17 don't have the banding which implies it's a screen problem....any ideas?

I hear the banding is glue that still hasn't dried properly ,apparently they were trying to ship them out the door a little too quickly...who knows !

128-bit floating point numbers on new AMD quad-core Barcelona?

There's quite a lot of buzz over at Slashdot about the new AMD quad core chips, announced yesterday:
http://hardware.slashdot.org/article.pl?sid=07/02/10/0554208
Much of the excitement is over the "new vector math unit referred to as SSE128", which is integrated into each [?!?] core; Tom Yager, of Infoworld, talks about it here:
Quad-core Opteron? Nope. Barcelona is the completely redesigned x86, and it’s brilliant
Now here's my question - does anyone know what the inputs and the outputs of this coprocessor look like? Can it perform arithmetic [or, God forbid, trigonometric] operations [in hardware] on 128-bit quad precision floats? And, if so, will LabVIEW be adding support for it? [Compare here versus here.]
I found a little bit of marketing-speak blather at AMD about "SSE 128" in this old PDF Powerpoint-ish presentation, from June of 2006:
http://www.amd.com/us-en/assets/content_type/DownloadableAssets/PhilHesterAMDAnalystDayV2.pdf
WARNING: PDF DOCUMENT
Page 13: "Dual 128-bit SSE dataflow, Dual 128-bit loads per cycle"
Page 14: "128-bit SSE and 128-bit Loads, 128b FADD, 128 bit FMUL, 128b SSE, 128b SSE"
etc etc etc
While it's largely just gibberish to me, "FADD" looks like what might be a "floating point adder", and "FMUL" could be a "floating point multiplier", and God forbid that the two "SSE" units might be capable of computing some 128-bit cosines. But I don't know whether that old paper is even applicable to the chip that was released yesterday, and I'm just guessing as to what these things might mean anyway.
Other than that, though, AMD's main website is strangely quiet about the Barcelona announcement. [Memo to AMD marketing - if you've just released the greatest thing since sliced bread, then you need to publicize the fact that you've just released the greatest thing since sliced bread...]

I posted a query over at the AMD forums, and here's what I was told.
I had hoped that e.g. "128b FADD" would be able to do something like the following:
/* "quad" is a hypothetical 128-bit quad precision */
/* floating point number, similar to "long double" */
/* in recent versions of C++:                       */
quad x, y, z;
x = 1.000000000000000000000000000001;
y = 1.000000000000000000000000000001;
/* the hope was that "128b FADD" could perform the */
/* following 128-bit addition in hardware:          */
z = x + y;
However, the answer I'm getting is that "128b FADD" is just a set of two 64-bit adders running in parallel, which are capable of adding two vectors of 64-bit doubles more or less simultaneously:
double x[2], y[2], z[2];
x[0] = 1.000000000000000000000000000001;
y[0] = 1.000000000000000000000000000001;
x[1] = 2.000000000000000000000000000222;
y[1] = 2.000000000000000000000000000222;
/* Apparently the coordinates of the two "vectors" x & y       */
/* can be sent to "128b FADD" in parallel, and the following   */
/* two summations can be computed more or less simultaneously: */
z[0] = x[0] + y[0];
z[1] = x[1] + y[1];
Thus e.g. "128b FADD", working in concert with "128b FMUL", will be able to [more or less] halve the amount of time it takes to compute a dot product of vectors whose coordinates are 64-bit doubles.
So this "128-bit" circuitry is great if you're doing lots of linear algebra with 64-bit doubles, but it doesn't appear to offer anything in the way of greater precision for people who are interested in precision-sensitive calculations.
By the way, if you're at all interested in questions of precision sensitivity & round-off error, I'd highly recommend Prof Kahan's page at Cal-Berzerkeley:

New I7 quad-core takes longer to boot up than old imac?

Just got my new I7 quad-core last night. (Looks gorgeous, by the way.) Transferred everything over from my old 24" 2.33GHz iMac.... all is well, only had one app hiccup so far (had to reinstall iTunes for some reason).
Anyway, did a side-by-side startup this morning, and the old iMac basically kicked the new one's butt - it started up about 50% faster.
Does this seem right? Is there a reason the new iMac, running basically the same exact system with same apps, preferences, etc, would take longer to boot up?

i think the new one was rebooting from a bootable backup i had created. changed that in startup disc settings... seems faster rebooting now.
and i transferred everything over via migration assistant (allowed it to move everything upon my first startup when it asked if i wanted to transfer data from another mac)....

New Mac-quad core or 8 core for youth club studio...

Hi there.
I have some money to kit out a studio in a youth club. I'm going the Mac route and Logic pro will be one of the programs we run. Once ive spent the cash thats it, so I'm hoping to go as powerful as possible.
I am looking at the new Nehalem quad core and 8 core models. At first I was going to opt for the 8 core (this may seem like overkill for a youth club, but I have worked with them for some years and we finally have a chance to get some really tasty kit!), but then I read the following article that suggested on paper that the 2.66ghz quad core is actually faster than the 2.26ghz 8 core;
http://www.macworld.com/article/139507/2009/03/macpro2009.html
I have been trying to find out if Logic Pro is a program that can make use of the extra cores. I am guessing not, but have not been able to find confirmation on this.
Question is, for longevity and a super fast machine, what would you recommend. I could get a slightly faster quad core than the base unit, but I am guessing in the future to go up to 8 core, you would need a completely new machine pretty much rather than upgradeing. I have mostly been a PC user, so these top end macs are a bit new to me.
Any suggestions would be greatly appreciated
Many thanks

I disagree that Logic fully uses all 8 cores (16 including the hyperthreading cores). Logic seems to max out at 8 threads, and it is able to take advantage of hyperthread cores. The result of this is that while it uses 8 cores on an octo machine, it also uses 8 cores on a quad machine (4 cores plus 4 HT cores), and the difference between the two is considerably less than it should be.
Hopefully soon there will be a version of Logic that uses 16 threads and takes advantage of HT on the octo machines, but in the meantime, much of the available CPU power is going unused. An octo can max out at 1600% cpu use, but logic is lucky to make it to 400%. It can reach that same level on a quad core i7. Same goes for Logic benchmarks, the difference in actual processing power isn't much, especially if the quad is at a higher clock speed.
Anyone who has an 8 core machine can test this, there's a Processor control panel that lets you disable cores (or hyperthreading). If you disable four cores, it will just use the hyperthreading cores instead with only a minimal loss of CPU power in Logic.

Pointer jumps all over the screen erratically on new MacPro Quad Core

I just powered up my new MacPro Quad Core Xeon for the first time today. For the monitor, my new Viewsonic VG2230. I noticed that my new mighty mouse was skipping all over the screen and it was hard to get the pointer on the place on the screen I wanted to click. It got much worse when I added the second monitor (Viewsonic VA1912), and didn't want to move across from one screen to another at first.
I thought maybe it was the mouse, and put on my old Razor Pro mouse, which I know and love. Same problems. I switch USB ports still the same.
According to Viewsonic, both monitors are compatible, and I have used the VA1912 successfully on my old PowerMac. I thought it was odd that the number of screens affected the problem, which is why I am concentrating on the monitors, but I wonder if it isn't a problem with my Mac.
Any ideas?

Hello g:
Welcome to Apple discussions.
I suspect a faulty mouse. However, try two things first. Trash a preference file (com.apple.bluetooth.plist) and restart. Reset the PRAM:
http://support.apple.com/kb/HT1379
Second, after assuring Apple this really was a problem, i got the ultimate insult. "If you would like to lodge a technical support ticket, we will need your credit card. This call will cost you $150.00."
You see, I bought this thing four months ago. Apparently you only get a 90 day free call period. After that you're warranty is actually a cost per call scenario…..
There is no Apple charge for a warranty issue and the mouse has a one year warranty. Call Applecare back (or take it to a store if they have one close to you). Unless I am badly mistaken, Apple will replace the mouse and pay for shipping both ways (I had one fail a couple of years ago myself). Do identify the call as a warranty issue.

New 27" Quad Core I5 or I7 and 64 bit Applications

I may be purchasing one at some point in the not too distant future and was wondering how exactly does the new iMacs and 10.6 work with 64 bit applications? I'm really in the dark about this, so I'm sure this sounds like a dumb question.
I run the usual Adobe apps but I also have a 3D app (Cinema 4D) that would greatly benefit from running in 64 bit. Is that something you have to switch on and off? How would you use 64 bit apps with 32 bit apps?
Thanks. Again, sorry if this is basic.
Bob

Performance; the i7 shows as measurably faster than the i5. Take a look at the benchmarks at the following sites:

I've purchased the new i7 quad core macbook pro and the us-428 tascam is not recognised by logic. What can I do? Please advise

Hello there. I've purcahsed the new i7 macbook pro quad core and the us-428 tascam is not recognised by logic.
I try to open audio/midi setup but it doesn't give me the option to choose the us-428 tascam. Does anybody know if there is a new driver for this i7 quadcore machines for the us-428 tascams? Please advise

The hardware has been discontinued... the last driver is from 2007.
Go here.
http://tascam.com/product/us-428/downloads/
Get the 3.40 driver, unplug the 428 from the mac, reinstall the driver (over the top of the other one). Reboot the Mac, after it's settled give it a minute.... then plug the US-428 in.
I don't hold much hope of the driver being SL compatible but it's worth a shot.
Just be sure the unit is unplugged when you install the driver.

Faint but regular clicks/pops in MBP (Quad Core 2011, 2.0) headphone output

I've seen some scattered posts about this. In my case it's definitely not the motion sensor as it happens if the computer is totally still. I can hear it with the audio turned all the way down and no applications running. It happens every 30 seconds or so-- there's a sharp click followed by a faint electrostatic hum for maybe a second or so. I'm sending it in to have it evaluated. I noticed it immediately upon setting it up for the first time. I reinstalled Snow Leopard and reset the PRAM, neither of which helped. If I install one of my audio interfaces (Saffire DSP Pro or M-Audio FW 410 but still using the Core Audio driver) it does not pass through the firewire to the device. Anyone else having this issue? My old MBP (first gen 2.0 GHz Intel w/CoreDuo) does not display this symptom.

Took my MBP into the Genius Bar and got a replacement and the new machine (out of the box and running Lion, whereas the first one was among the last to ship with SL) behaves identically. I'm wondering if this is a feature, as I'm just now realizing that what I'm hearing may be the audio driver or headphone jack periodically switching on and off. I can make the click happen by doing anything that calls on the core audio driver. This may be clicking on a song in iTunes or even switching between tabs in Firefox if one of them has a lot of streaming content. The click is followed by a little bit of hiss; then, if I do nothing, there's another click maybe 30 seconds later and the headphone port goes completely silent. The 'hiss' is, I suspect, just the normal background noise on the output. When there's actual sound being output (a song, flash video, QT playback etc) there are no clicks or other artifacts. Likewise if I listen to the headphone output for 10-15 mins while doing nothing else (big fun, let me tell you).
If that's what's happening it's an annoyance but not the end of the world. I can't think of a good reason why it should behave like this (i.e. to save power or otherwise redirect resources) and it reeks of crappy hardware or coding, but if it's not affecting the actual headphone or firewire audio output when sound is happening I can live with it.
I could be totally off the mark and for all I know tomorrow it could be doing the above and clicking randomly during audio playback. Curious to know if anyone else who is having this symptom sees the same pattern.
Cheers.

New MBP - should I stay with Snow Leopard or jump to Lion?

Running Final Cut Studio 3 I have just upgraded our older MBP15 Core Duo to a nearly new MBP15 Quad-core i7. I will install FCS3 on it and wonder if Lion is stable with FCS now? Any thoughts?

I agree with Robert .. You really need to ask yourself why you would need Lion. I have a total of 7 various MACs from MBP to Air's and MAC Pro all stillrunning Snow Lep ..all because it does all I need and I can use FCS3 in a very stable and workflow way that suits me. I know the foibles and have no need for FXPX either. I see Robert runs both and have read on many occasions other doing the same. I have also read others having issues .. it seems to be dependant on how you upgrade .. I have no need so do not change .. I also drive a four year old car for the same reason ..

Will illustrator cs2 run on imac quad core?

will illustrator cs2 and photoshop cs run on the new imac quad core? if not, which versions will run?

Only the very latest versions will/could have updates for 10.7 Lion as the OS was just released and doesn't run "Rosetta/PPC" based programs which those most likely are.
Guess you milked Adobe for as long as you could, perhaps you can buy a used machine?

Dual or quad core ?

I find blog articles on the web saying the Excite tablets are all quad core, but then I see other articles and shopping sites (e.g. Amazon, eBay) saying the Excite 10 LE is dual core. I am confused. Can someone clarify which of the Excite tablets are dual core and which are quad core?
Solved!
Go to Solution.

Excite 10 and Excite 10 LE are different products. Excite 10 LE (dual-core) is currently available. The press release is announcing new tablets (quad-core).

Brand New 27" Quad- Odd Error message w/Disc Doctor.

I just got a new 27" quad core iMac. My pre-pentium G5 went down again, I see I was not the only one that stuck with a lemon.
After installing Final Cut Express HD and the normal needed programs like WMP and A. Reader my beloved fish tank from Aqua Zone 7 sea's on my new machine I restarted and ran Disk Doctor. I got an error code that alarmed me
Warning SUIDfile"Systems/library/coreServices/RemoteManagement/ARDAgent.app/Contents/Ma cOS/ARDAgent has been modified and will not be repaired.
I also ran DD from the install disc and still got this same error code.
Any ideas? Is this a big deal? How can I repair it? and also
What does this mean?
I appreciate any thoughts, insights.... I want this MAC to work Great right from the beginning.
Seeing this wonders if my system has been modified somehow. I was on the phone several days back with the ISP that holds my e-mail account so that I could set my mail up again in the settings. I never released any power over my machine so that he could access it remotely.
