MacBook Pro :: What's Difference Between DDR3 1066 And 1067 Memory

I want to upgrade to 8GB memory. My MBP has 4GB of DDR3 1067 and I see mostly 1066 memory out there. Is this a significant difference?

MacBook Pro :: Difference Between "certified Compatible" And Regular 1066 DDR3 Ram?
Corsair "CT" series (certified) vs. "CM" series (regular)

Kingston "KTA" series (certified) vs. "KVR" series (regular)

I can't find any vendor that carries the certified Mac compatible series where I'm from (and shipping from the US will wipe out any savings vs online apple store). Has anyone tried using the Kingston KVR1066D3S7 with their uMBP?

MacBook Pro :: Upgrading RAM - 1066 Versus 1067?
I have a new MacBook Pro unibody currently holding 4gb of ram. I'm looking to upgrade that total to 8 gb with the following from Amazon: Kingston Apple 8GB Kit (2x4GB Modules) 1066MHz DDR3 SODIMM iMac and Macbook Memory (KTA-MB1066K2/8G). The only potential problem I'm seeing is that my current 4GB ram set is rated at 1067 mhz and the Kingston ram, as well as others, is listed at 1066 mhz. Will that Kingston 1066 work in my Macbook Pro?

MacBook Pro :: Kingston Ddr3 1066 8gb (2x4gb) Work On 13" Unibody?
I purchased a brand new Macbook Pro from Best Buy a few months back, it is the 13" unibody with a 2.26 ghz dual core processor and came with 2gb of memory installed. I just bought the two sticks of memory from [URL] which were Kingston DDR3 1066 204-pins, 4gb each. My friend told me that my Macbook Pro will only support up to 6gb, but my manual says that it supports up to 8gb. He also said that people have been having trouble with their motherboards by installing too much (8gb) of memory. I've done some research and looks like I'm good to go, but just want some reassurance before I install the new memory. One last thing, he also told me that 8gb is only supported on the i7 processors?

IMac :: Use 1066 Ddr3 In 2010?
I ha e 2x2gb of 1066 ddr3 ram sitting here. I am going to buy an iMac. I can't decide between the refurb 27 core2duo, the refurb 27 core i5 or the new 21.5" i3. Of course I am torn between cost and performance. I would prefer the bigger display but it's not necessary. If I could use my existing ram in the new 21.5 that may put it as the winner but I am unsure if I can mix 1066 and 1333 ram or not. If not then I will probably get the refurb 27 and then it's just to decide between i5 or core2duo

I just bought my mom a new iMac today that has 2x 2 gig 1333 MHZ cards. I want to also add my 2 old 1067 MHZ cards from my old iMac. This would total 8 gigs for those counting. Good idea? Will it cause the 1333 MHZ to run at 1067 MHZ? Is this worth doing to get the 4 extra gigs of memory?

Mac Pro :: Registering Memory Speed Of 800 MHz Instead Of 1066
I just bought a new MacPro - Quad-Core Nehelem 2.8 GHz. Before booting the first time I installed four Kingston 8Gb DDR3 ECC DIMMS, 1066 MHz (registered, with thermal sensor). It shows 32Gb memory installed, but lists their speed as 800 MHz. I assume this is a sign of a memory problem, but I'm wondering if there's some hardware or OS issue I'm missing.

Final Cut Pro :: Memory Placement (DIMM With 8GB DDR3) Formation
I have a 2 x 2.26 GHz Quad-Core Intel Xeon with 8 GB 1066 MHz DDR3. It has 8 DIMM slots, with 2 GB DDR3 1066 MHz sticks in slots 1,2 & 5, 6. This is the correct formation according to this manual by Apple: [URL]. However, this is a quote from the manual, "Note: Populating slot 4 or 8 slightly drops maximum memory bandwidth, but depending on the applications used, overall system performance may benefit from the larger amount of memory." pg 4. I'm guessing that because slot 4 drops the bandwidth, the memory is configured on 1,2 & 5,6. If I move the memory from slots 5 and 6 into slots 3 and 4, will this increase performance for Final Cut Pro and Motion? I am using current versions.

MacBook Aluminum :: DDR2 Vs DDR3 - Frequency Of Memory Will Rob Lot Of Performance Or Not?
I really want to upgrade the memory on my 6th generation MacBook. It's the aluminium one and the 13". They recently rebranded this model to include it in the MacBook Pro line. Nevertheless, I know Apple sells a $200 2x2GB 1066MHz DDR3 modules. I have also been considering a pair of 2x2GB 667MHz DDR2 modules for about $130. The frequency of the memory will rob a lot of performance or not? Should I just spend the extra money on the Apple module?

Mac Pro :: Adding Memory - Any Speed Difference?
I currently have 6GB of Ram is my Mac Pro and I want to upgrade to 16GB. My question is whether the arrangement makes any difference in speed. I can get 8 2GB modules for under $300, but getting them in 4GB modules would be about $900. Is there any major speed difference is having them in the 4GB sticks? I do mainly video and photo editing and use Adobe Creative Suite.

MacBook Aluminum :: Doesn't Restore Memory To Flash Memory After Files Are Removed
For every flash memory device i use (flash drive, mp3 player, etc.), when i remove files from them to the trash, the memory is still being used on the device. For example, when i tried to take a song off my mp3 player, it allowed it but the remaining memory was the same as before. i experimented by moving every song out of the device so it was empty but the memory was still being used. Does anyone know how to fix this because i am at the point that i can no longer used devices because it claims to be full.

MacBook Pro :: MBP 5.1 Capable Of Using 2x 2GB 1333MHz DDR3 RAM?
I would like to update my MacBook Pro 5,1 with two 2GB modules to 4GB. The current RAM is running on 1066MHZ but the new modules at my computer place are only available with SO-DIMM 2GB DDR3 1333MHz.

Would the MacBook Pro 5,1 work with two SO-DIMM 2GB DDR3 1333MHz RAM modules too?

MacBook Pro :: Difference Between The 15' And The 13'?
I'm kinda' new to the whole audio recording process and I'm leaning more towards the 13' MBP bc the only difference between the 15' and the 13' is an optical in line. So, what does the optical line in do? And is it worth the extra $200 because i do not think 2' of monitor space is?

I'm currently looking at a 13.3 MBP and looking on Dixon's website there are two different options either the Z0J72B/A or MC374B/A?

The specs look the same and the price is the same so which should I go for?

The MBA is also looking tempting after reading some favourable reports on here and I'm sure I can get a cheapish external dvd drive should I need one every once in a while.

MacBook :: Technical Difference Between Air / Pro's Screen?
It is widely known that the macbooks screen has poor viewing angles and black glowing problems. I found an article that explains why this is so and why the macbook air does not have this problem. Originally all TN based lcd screens suffered from this. To help this problem manufacturers came up with the idea of adding additonal films to fix these viewing angle difficulty which increased the viewing angle threshold before that screen inversion occured (black becoming white/white becoming black and so forth). This article gives a technical explanation of it.Quote:Birefringent film increases LCD viewing angleSunny BainsTwisted-nematic liquid-crystal displays (TN-LCDs) have two major disadvantages when being viewed by more than one person. The viewing angle of the display is limited, and there are gray-level "inversion zones" in which black becomes white and vice versa. Researchers at the Fuji Photo Film Company Ashigara Research Laborato- ries (Kanagawa, Japan) have developed a method of pre- and postcompensating for the birefringence of liquid crystal, thereby increasing the viewing angle but without sacrificing brightness.

The link between birefringence and viewing angle in a TN-LCD is not obvious. Displays are generally backlit with a wide-angle light source. The light first passes through a polarizer that discards about half of it and allows the remainder to pass. This light is now polarized parallel to the direction of the liquid-crystal alignment at the bottom of the liquid-crystal cell. The orientation of the crystal changes gradually, however, twisting and tilting so that the alignment at the to�of the cell is perpendicular to that at the bottom. The polarization of the light will be rotated with the orientation of the liquid-crystal molecules. The light can then emerge through a polarizer at the to�of the cell, which is crossed with the polarizer at the bottom.

This technique only works properly, however, for light coming in at right angles to the cell. Though light entering at, say, 30 has the same nominal polarization as the light that is normally incident--because it passed through the same polarizer--the 30 light experiences the liquid-crystal cell very differently. The polarization components are effectively tilted and so are not as compatible with the birefringence of the tilted, twisted-nematic liquid-crystal molecules. Instead of being neatly turned, the polarization of wide-angle light can be severely skewed by the cell, with perpendicularly polarized components being "pulled" in different directions. Such unwanted manipulation means that much less of this light makes it through the second polarizer and so into the corresponding output angle for the display.

The only way to work around this problem is to make the light travel through the same kind of chemical structure but with opposite (negative) birefringence properties (see Fig. 1 on p. 53). In this way, any polarization skew can be inverted and subsequently neutralized. Fuji researcher Hiroyuki Mori has accomplished this by using a negatively birefringent discotic compound--a substance made u�of disk-shaped molecules--and tilting them to emulate the liquid-crystal structure.1,2 The "twist" is achieved by "crossing" the films--matching their orientations to the rubbing (alignment) direction of the to�and bottom of the liquid-crystal cell (see Fig. 2).

By using the compensator film, Mori was able to enhance the vertical and horizontal view zones of a TN-LCD and completely eliminate the upper inversion zone. For instance, the upward vertical angle at which the contrast ratio dropped to 10 (from 100) increased from about 25 with a normal display to 40. The lower inversion zone, which could appear when viewed from almost any angle below the normal, was pushed down so that it could never be seen above -20. It could not be eliminated, however, because the compensation film is not active and cannot, therefore, compensate for pixels that are off.

Though making the compensation film switchable is not currently being researched, other improvements are possible. In particular, Mori`s simulations show that birefringence compensation would be more effective if the "twist" of the compensator more accurately imitated that of the liquid crystal.This is now referred to as TN+FILM and is used in almost every desktop lcd.

The macbook does not have those compensation films which is why it has a poor contrast ratio and has poor viewing angles. The macbook pro and air have these additional films as do most non apple computers with the exception of a fewer low end manufacturers.

MacBook Pro :: 15' I7 - 5400 RPM Or 7200RPM Difference?
I've come to the conclusion that I will be opting for the 15" i7 MBP, after originally wanting to go for the 13' (due to lack of ix processor and such).

My dilemma is that I want to purchase the MBP through Bestbuy/Futureshop, mainly so I can go on a payment plan of around $100 per month, rather than dishing out $2000+ in one shot.

The issue with this is i am unable to BTO my MBP, so I will be stuck with the 5400RPM HD. Is it really that much of a difference from the 7200RPM HD? I'm used to a 7200RPM HD on my imac, so I don't want to feel any slowdowns.

Also, on my 20' early 2009 iMac, I notice that I need to turn my brightness down to about 3/16 (can't really explain it any other way. i guess this would be good with the MBP, as i'd get longer battery life, haha) or else i'll get a headache fairly easily after about 30-45 mins of use. Would the matte option help with the headaches?, as I assume the glossy screen is part of the cause for the headaches on my imac. I had originally returned the 24' imac i purchased and went for the 20' because the screen was too large.

So I am somewhat torn between going for the 15' i7 from a reseller, or just biting the bullet and ordering through the apple site.

MacBook Pro :: Memory In Activity Monitor Not Equal To Installed Memory?
I have a June09 13" Macbook pro which I ordered with 2gb ram. I replaced the original memory with 4gb a week ago. Computer is running fine.

I checked Activity Monitor today and it is showing Free Memory +Used Memory as being about 3.75gb rather than 4gb in the detailed breakdown of memory usage on the left (used = wired+active+inactive), although it is showing 4gb in the small pie-chart on the right in Activity Monitor. This total of 3.75gb doesn't seem to change.

MacBook Pro :: Inactive Memory Takes All The Memory?
I have a Macbook Pro - August 2009, upgraded version to 2.66 MHZ, advance display card, Dual core. I recently upgraded the RAM to 8GB (Kingston) to clear more memory for my massive application use, the thing is it didn't solve anything because the issue I had problems with - Inactive Memory, wasn't resolved.
Inactive memory supposed to hold the memory for the apps you closed in case you'll run them once again, but it NEVER clears the memory, I can see the "blue" color taking all the free mem and the computer slows down! no free mem what so ever.

Now the Inactive mem grows enormously and gets to be more than 4GB, it has the same effect, the memory runs out!

Is there a way to fix it? I'm going crazy with that.. what a terrible design! iFreeMem doesn't work on the 8GB, I'm at a loss..
