The trick of expanding the memory yourself by buying cheap Kingston modules in order to save a few euros when buying an iMac, MacBook, MacBook Pro, etc ... is known but it is not as simple as it seems since Kingston has two types memory of each class. One of the types has a reference that begins with KVR- and the other begins with KTA- being this second a little more expensive than the first but it is the one that really works without problems in our Mac's since apparently we have verified that although it has the Same chips and everything is apparently the same, it has passed much more rigorous tolerance tests than the KVR-xx models of the same brand. The references follow these guidelines:
KTA- [computer] [speed] [capacity] that is, if we want 1 Gb of memory for a MacBook we have to look for a module called KTA-MB667 / 1G and NEVER one called KVR-xx667 / 1G or KTMxxxxx ... ALWAYS KTA.
Here You can see a Kingston site with a very useful form to know what memory to search for each type of Mac.
I do not recommend it for Mac, you see that it says KVR (Kingston Value Retail)
This type of memory does not pass the technical requirements of Macs and can cause problems. It is a question of tolerances. Try to find Kington's KTA instead of KVR
I JUST PURCHASED A 1GB MEMORY FOR MY MAC MINI PC G4 AT 1.42 GHZ. UNFORTUNATELY I HAD NOT CHECKED THE INFORMATION THAT YOU SHARE HERE AND SO IT IS A KVR. I ALREADY TRIED TO EXCHANGE IT FOR THE KTA, BUT THEY MENTION THAT THERE IS NO OF THAT MODEL AND THAT IN THE END IT IS THE SAME AS THEY ARE ONLY MARKETING KEYS. WHAT PROBLEMS DO YOU THINK MAY CAUSE WHEN INSTALLING THE RAM KVR? THANKS
AARON, I installed 2GB in Kingston's gig for the PowePC G5, and at least once a week it shuts me down. It's that simple ... it turns off.
The first thing that the technical service has asked me is that it must be the memory (they will be stung for not having called them ...) but the truth is that it is not KVR.
A greeting.
hello, I have an iMac G5 at 1.8 of 17 ″… I don't know why it comes with 256 of ram .. (?) They sold it to me like that, a friend, of course .. and I don't think a mac comes with that low memory. .
Anyway ... my friend does not see why ... he does not know an iota of that.
What memory can I put, that is, what memory capacity could I buy it ... ?? And, they only sell kingston for mac or is there another recommended brand .. ¿?? Well, I have read about the non-removable memory of the imac.
Thanks in advance for the answer.
And regards.
Hello, I would like to know if I mount a 27 ″ imac with an i7 processor, 4 KVR modules of 4G in total 16 G, if I will have problems as you say, or will you hardly notice anything?
Hello, I would like to know what could happen if I mount 4 KVR1333D3S9 modules in a 27 ″ i7 processor imac, it would be a total of 16 gigabytes, would this affect you, would it slow me down? if they are apparently the same and it is the same chip ..?
