If service center can somehow trace back the damage to be user-caused, then they can reject the warranty claim. But most of the time they are too busy to do so.

the normal notebook RAM. no word on the vengeance

I would be the first one before this to say that the RAM you use may not affect your performance. I am now retracting back that statement.

Bought a pair of 4GB KVR Kingston to upgrade a 13" Pro. Immediately I noticed that :-

1. Power reading is all over the place, running down the battery about 2 hours faster.

2. The system feels sluggish, especially when you do a lot of encoding movies.

Did the whole memtest thing, nothing came out. In the end, installed it in a Windows notebook and did diagnostic, no problem.

Or maybe it was just the Kingstom ram. Anyway, ordered A-spec ram and things are running much-much better. Corsair at RM120 for 4GB.

^ wow that's new. thanks for sharing mfitri77

anyone else noticed the same symptoms?

@mfitri77:
which type of corsair RAM that u use for the latter. planning to get 2 pair of 4GB RAM for my iMac.

i reckon one should get kta chips
I'm working in a authorized reseller of apple
everyday i see ppl use a 8gb corsair ram on their 15" got prob with it cannot boot and hang.. switch back the ori wan can work already!

Sorry, but that is nonsense. The only way you mac cannot boot or hand is if you didn't install the memory right or you put in wrong memory, or you are talking about PowerPC macs. In fact, I have used a lot of corsair rams before, and mushkin in a lot of macs before without any problems. Even then, the symptoms of a bad memory doesn't usually manifest themselves that clearly. Or maybe it's just placebo effect.

The ones that do give me problems are KVR rams, or any Kingston, to be exact. A lot of resellers are selling Mac tested ram, for me I would recommend Corsair Mac rams if you could get them, barring that, get the mushkin or normal corsair ram. In my experience, they have the least problems when paired with an intel mac.

Whatever you do, don't go to Authorized reseller like MacXXXXX la or MacXXXXX la. That is like going to sacrifice yourself at the altar of stupidity of paying a premium.

hi mfitri77,

I'm new here and am planning to get my imac's 4gb RAM upgraded to 8gb. where can I get the corsair 120rm which is compatible to my imac?

and also, im not sure how to put it in, so do you recommend anywhere who can do it for me?

You can replace back the original DVD rom back to its original n replace back all original part before send in for warranty.

I never used iMacs before, since most of my power desktops are windows based. As far as I know, they use the same memory as notebook sized rams, and yes, the memory bay doors are just below your iMac, check the apple website for specific details on what ram to buy according to your iMac version.

Normally get my rams from either Viewnet, or C-Zone.

Actually any SSD will do but since ur on a new 2011 mbp I suggest to go for the Sata 6Gb instate the old Sata 3Gb since ur Mac can easily boost to 5xx+ transfer rate.

The different between the apple SSD vs Conventional SSD is the trimming enable. But you actually can enable it with a simple hack. Just google around.

By the way I'm already upgrade to SSD 256Gb and it's faaaaaast.

Added on December 20, 2011, 3:07 pmAs always I will recommend to replace ur Mac ram to apple certified ram. But most just ignore as reason value ram work perfectly.

As its ur money and it's ur work that you put on risk as application crash or more worst kernel panic.

im using macbook unibody late 2008. im thinking of upgrading ssd 120gb. any suggestion? intel? crucial? samsung? owc?

Whatever brand also no problem. Only think is that you need to enable trim manually. That's all. I'm using 3rd party SSD on my mbp unibody 2008.

Im working in an authorized reseller la... rams we are selling are same price as czone... there was 2 customers using mush kin ram on their mbp 2011 and after a few months they came back and when the thing ran memtest it auto shutdown.. change back to ori ram no prob at all... so any explanation for this

u can drop by at out shop... charge the same price for ram like u buy in view net etc

heap the simplest way

i store is by czone so we help replace ram same price as czone

how to do that

brucess, which apple reseller shop are you in? never knew about apple reseller selling rams too.

Most apple premier reseller and campus store do sell apple certified ram. Only lowyat Recommend value ram to replace ur apple certified ram. So don't shock that apple reseller sell rams.

i do sell normal rams not kta.. and we do provide installation for it

maybe the mushkin pair is faulty anyway. as in, even if installed on a windows laptop, will get same problem

but again, that's just 2 customers out of a lot more who are using mushkin on their macs without any problem at all. just keep in mind, they're not compatible 100% of the time, but close to. im not sure if can claim warranty or not if normal RAMs cannot work on macs

Mostly it won't replace as normal ram are not recommended for Mac. As muskin does sell apple certified ram for use in Mac but the price is much expensive compare to its PC ram.

Although value ram ideally should work in Mac, but I'm indeed seen some weirdo cases, which they cause kernel panic
Switch to KTA ram, the response is different. I have even conducted test before.
