HT1270 A 1226- Kingston KVR667D2N5/ 2G 2GB DDR2 667 Can I use this memory card?

Is here someone who can help me with this issue?
Is this Memory card compatibe with my A1226?
I wanna upgrade to 4GB.
Thank You

The specifications are correct... however, among Mac users the Kingston "value RAM" has earned a reputation for failure.
In the US I recommend Mac users buy memory from OWC / MacSales or Crucial. I also recommend you avoid Kingston.
If you cannot buy from them see if you can find a source for Hynix memory.
Here is one: http://www.amazon.com/SODIMM-200pin-PC2-5300-Hynix-HYMP125S64CP8-S6/dp/B002TWOGZ 2/

Can i use 4gb ram card instead of (2x2) 2gb cards in macbook pro 15" 2.0 ghz

Hi John,
If your MBP is a 2011, yes, and here is one example: http://eshop.macsales.com/item/Other%20World%20Computing/1333DDR3S4GB/
If your MBP is from 2006, the other year Apple made a 2GHz, the answer is no, as the max RAM is 2GB.
Given that it appears you already have 2x2GB installed, I'm "guessing" you have the 2011 model, so the answer is yes.

DDR2 667 shows up as DDR2 800 for some reason,,

Hi all,
My "problem" is the following..
I just bought myself 2 new Kingston 2GB DDR2 667 memory modules. Thus expanding the memory of my macbook to 4GB's of ddr2 667. Now when i enter the system specs @ " About this mac" the system tells me i am actualy running 4Gb's of DDR2 800 mhz memory..
I thought the white MB881M/n macbook didnt support 800mhz memory..
Now my question is:
Would it be wise to buy 800mhz ddr2 and use THAT in stead of using the 667mhz memory wich the machine is obviously overclocking.
And IF the machine is actualy overclocking the current memory, could it be harmfull? Will it actualy be faster at 800 then at 667? Is the machine actualy overclocking the memory, or is it just a bug in the system showing 800mhz in stead of 667?
I thought the macbook i have couldnt support 800mhz but if for some reason it can i think it would be "wise" to put the "real deal" 800mhz in it..
Cheers

Well, OS X has no built-in capability to overclock RAM. Doing so requires overclocking the bus and that would require special software (I don't think any such software exists for Intel Macs.)
The documentation I have even on the Early 2009 White Macbook specifies DDR2-667 MHz RAM. I don't know why System Profiler is reporting 800 MHz.
Here's my (multi-part) theory, and it's from thinking about all the reports we've been hearing about older generation MacBooks and the newer white MacBooks.
People have been reporting that the lastest (early 2009) white MacBook does actually use PC2-6400/DDR2 800 memory and runs it at native speed. It's not actually "overclocking" anything; it's actually capable of it even if not documented by Apple. It's using the same NVIDIA chipset as the Unibody MacBooks, and they're capable of using PC3-8500/DDR3 1066, so it's not a stretch to believe that they're capable of using DDR2 800. Intel's latest chipsets are capable of using DDR2 or DDR3 modules, but the type is going to be limited to the physical socket type.
All reports are that correctly labelled PC2-6400/DDR2 800 memory doesn't work properly in any of the earlier MacBooks that specify PC2-5300/DDR2 667 except in cases where it's mixed with one slower speed module. One would think that the SPD should contain secondary settings, but that doesn't seem to help it work unless there's another slower speed module that forces the memory controller in the chipset to operate both at the same speed.
A few people who have purchased Kingston (especially the KVR "ValueRAM Series") DDR2 667 modules have reported similar incompatibility as with clearly labeled
DDR2 800 modules. Here's one report:
http://discussions.apple.com/message.jspa?messageID=9507719
My final theory is that these modules are sold by Kingston as DDR2 667 but are in fact DDR2 800 modules. This would A) cause the older MacBooks to not recognize it alone and B) cause the newer MacBooks to run it at a faster native speed.

Can I use kingston ddr 333 along with Kingmax ddr 333

Ok I wanted to add some more memory to my system I have 2 x sticks of 256 ddr 333 Kingmax right now. I would like to add some more ram but I cant seem to find Kingmax memory online I can find a stick of 256 but not a 512 I see alot of Kingston 512 stick and 1 gig can I use Kingston along with Kingmax ram? I dont want to spend too much on this upgrade since I will be upgrading my Mobo and Cpu in a few months and this memory would be too slow for a new system.

A question for you, what do you mean by specification?
Product specifications, module specifications, component specifications.
Quote
No its not, you dont know the PCB revision, make, model.
I would not mix double sided with a single sided module.
lol! Its not 1994 anymore. Where have you been? Mixing DRAM speeds, capacities, and timings has not been a significant issue for years now. Memory controllers are designed[/i] to accomodate separate timing and speeds for each memory bank.
Remember VIA Apollo Pro133/133A (VT82C693/694X) from way back in like 1971?
Quote
VT82C694X DRAM controller supports standard Synchronous DRAM (SDRAM) and Virtual Channel SDRAM (VC SDRAM), in a flexible mix / match manner. The Synchronous DRAM interface allows zero wait state bursting between the DRAM and the data buffers at 66/100/133 MHz. Six banks of DRAM can be composed of an arbitrary mixture of 1M / 2M / 4M / 8M / 16M / 32MxN DRAMs up to 1.5GB.
Remember KT133/KT133A (VT8363)?
Quote
VT8363A Advanced High-Performance DRAM Controller:
-Different DRAM types may be used in mixed combinations
-Different DRAM timing for each bank
-Mixed 1M / 2M / 4M / 8M / 16M / 32MxN DRAMs
-Flexible row and column addresses
-Independent SDRAM control for each bank
nForce and nForce2:

The TwinBank architecture is designed to provide a high degree of flexibility, scalability and upgradeability. Its technical benefits include:
• Both 64-bit and 128-bit operations. In 64-bit mode, the DIMM can be located on either MC1 or
MC2. In 128-bit mode, both MC1 (DIMM0) and MC2 (DIMM1/DIMM2) are utilized.
• Both controllers are functionally identical with all control and timing parameters independently programmable. This allows asymmetric DIMMs with different memory organization, size, and speed to be used on MC1 and MC2 and still provide the full performance benefits of the 128-bit memory system.
• Support for odd total memory size; eg. 64MB + 128MB = 192MB, while still taking advantage of
the 128-bit TwinBank architecture.
Quote
NFORCE2 DualDDR Memory Architecture
Both of the memory controllers on DualDDR are functionally identical with all control and timing parameters independently programmable. This flexibility allows the users to populate up to three asymmetric DIMMs in any organization, size and speed. DualDDR simply adjust to the lowest common density that will facilitate 128-bit bandwidth, allowing a wide variety of different DIMM combinations to operate reliably regardless of the individual density and latency characteristics.
SIS 655FX/655TX:

Flexible Dual Channel
This feature allows users to “mix and match” memory sizes and odd number of sticks to operate in Dual Channel mode.
Do you think memory controllers have become less[/i] sophisticated since the days of VIA VP3 Socket 7 (which, BTW, also supported arbitrary DRAM mixing)?
The ability to run different speeds, sizes, and densities of DRAM isn't just an accidental byproduct of advancing memory controller technology. It is intentionally being built-in[/i] to the design to accomplish this.

Qosmio G30-102 - Can I install Kingston DDR2-667 RAM insted DDR2-533 RAM?

Hi
I've got a Qosmio G30 102 and I wanted to upgrade my RAM to a total of 4GB (currently I've got 2GB installed with specifications of PC2-4300 DDR2 (533MHz)) . So I've been searching for RAM and I wanted to know would it be possible for me to install.
*Kingston Technology - 2GB PC2 5300 DDR2 667MHz 200pin Memory SODIMM*. Would this work correctly and if so would it be better than getting a (*1GB) Memory PC2-4300 DDR2 (533MHz)* i.e. the standard RAM installed on my Qosmio???
Thanks in advance for th answers
Mo

Hi!
For upgrading RAM on my notebook I have used Kingston DDR2-667 and it works without any problems! :)
So you can use this Kingston module too but I assume that it will only run on 533 MHz speed due the FSB limitation of the CPU. The FSB speed you can check with a hardware information tool like Everest or PC Wizard 2008 for example.
As far as I know the notebook can be upgraded to 4GB maximum RAM.

Can I Use DDR2-533 (PC2 4200) ?

2x Kingston HyperX 2GB KHX4200S2LL/2G DDR2-5300 (PC2 4200)

Kappy wrote:
PC2-4200 RAM is not PC2-5300 RAM. The former is DDR2 533 MHz and the latter is DDR2 667 MHz. You cannot use the former if your computer requires the latter. Your model requires DDR2 667 MHz PC2-5300 RAM, not PC2-4200.
Actually it should work but with what should be an obvious performance penalty. I've tried it (used PC2-4200) myself on my late 2007 model when I was bored and had access to some PC2-4200 modules from another computer that was upgraded. I've read the Intel chipset datasheets, and they've always had backwards compatibility in mind. The MacBook4,1 designation is for the last of the Intel chipsets. I'd also take a wild guess that the NVIDIA chipset versions might work with PC2-4200, although it's been reported that they work with PC2-6400.
If PC2-5300 is mixed with PC2-4200, it should read as DDR2 533 in system profiler. The default when speeds are mixed is to run both at the same speed. I tried all sorts of combinations including 2 GB (PC2-5300) + 512 MB (PC2-4200), 2x512MB PC2-4200, 512 MB (PC2-4200) + 512 MB (PC2-5300).
Apple doesn't exactly tout this as a feature, but in my experience it will work. It's not an ideal solution and frankly I wouldn't go out of my way to get PC2-4200. However - I've tried it myself out of curiosity and found that it did work - at least in my machine.

I have a mid 2009 13" Mac Book Pro. I want to upgrade the RAM from 2GB to 4 GB. Can I use 1333 MHZ modules instead of 1067 MHz?

The manual suggests 1067 MHz modules but my dealer stocks only 1333 MHz modules. Can I use two modules of 2GB 1333 MHz in place of the present two modules of 1GB 1067 MHz.

I wonder if perhaps the new ram isn't exactly right for the computer? When you install a 2gb and one of the 4gb and go to Apple-About This Mac does it show up as 2gb or 6gb? Just thinking perhaps the computer can't read the 4gb cards at all, so as long as one of your old 2gb cards is there to function it doesn't freeze (seems like an odd concept but I've seen it happen in PC years ago, so not sure if it's even possible with current hardware or Mac but it's a thought).
Also, double-check the sticker on your new Ram to be sure it works with your system (http://support.apple.com/kb/HT1270) thinking maybe even if you bought the correct package in the store, maybe it contained the wrong product? You didn't say what screen size you have, but it looks as though they are all the same specs (13, 15, and 17-inch MBP mid-2010):
- Double Data Rate Small Outline Dual Inline Memory Module (DDR3) format
-30mm (1.18 inch)
- 2 GB or 4 GB
- 204-pin
- PC3-8500 DDR3 1066 MHz type RAM
I did a quick search and found this thread, same issue, so perhaps it may contain some clues as well: https://discussions.apple.com/thread/3797144?start=0&tstart=0 I noticed someone mentioned the brand or source of the purchased ram; I have personally had issues with third party or "other than what the manufacturer recommends" brands of memory over the years. I bought mine from Amazon.com but made sure it was Crucial brand, which I've always had high success with.

Can i use 2gb memory in one slot in my 2006 Mac mini as the 2 slots of 1gb only reports only 1gb memory, both memory work ok in the one slot

Can I use 2gb memory in one slot in my 2006 Mac mini as the 2 slots of 1gb only reports as 1gb memory, both memory work ok in the one slot as I have swapped them over

To my knowledge 1GB modules are the max. size for the 2006 Mini.
2GB modules are not recognized/useable.
Sorry
Stefan

I am now a subscriber to the Creative Cloud. I had read about it, that this includes 20 GB of memory. But in my cloud, I find only 2GB. What can I do?

Is there anyone who can tell me more about my Question?

Yes, that is correct as the part number that you have placed the order is for 2GB. You can get this order cancelled & place a new order with the correct part number, you can contact our Support at http://adobe.ly/yxj0t6
The cancellation fee can be waived off if you re-purchase. Please let me know in case of any issue by personal message box.
