Corsair CMSA4GX3M1A1066C7 Apple Certified 4GB (1x4GB) DDR3 1066 MHz (PC3 8500) Laptop Memory 1.5V

I finally got fed up with memory-hog Chrome slowly killing my 2010 Macbook Pro (4GB RAM), and decided to upgrade. I researched the proper specs, and read reviews of a lot of different suppliers on Amazon, searching for "2010 MBP" or "2010 Macbook Pro" to make sure that other users had a good experience with this particular brand of memory---there were quite a few positive reviews for this memory in the 2010 MBP (and a few negative ones), so I bought it. BIG MISTAKE!!!The original Apple memory (2 x 2GB) came out easily, and I put the new 2 x 4 GB Corsair memory in---it went in and appeared to be seated correctly, though it felt like a tighter fit than the original memory. Spoiler alert--it IS tighter than the original memory; the Corsair sticks are fatter than the Apple product, and this caused no end of problems!!I turned my laptop on and got the deadly 3 beep code indicating that there is something wrong with the memory :( I took the computer apart to remove the memory sticks, and found that they were almost un-budge-able! I got the top stick out after several minutes of maneuvering and retried the computer to see if I could get a startup screen with just the bottom stick---nope, still the 3 beep code of death, so clearly the bottom stick wasn't working and needed to be taken out.It took close to one hour and a lot of blood sweat and tears to get that damn bottom memory stick out. I put the old Apple memory back in, turned it on, and got a white screen with a flashing question mark--Apple's equivalent of the blue screen of death, indicating there's a serious hardware problem.Long story short is that google suggested that the data cable in these MBP 2010s is prone to failure if at all stressed, so I bought one, along with a hard drive enclosure to test my original drive. Sadly, although the hard drive worked outside the computer in an external enclosure (using the original Apple memory inside), it didn't work inside the laptop (nor did a brand new drive) and the new data cable didn't fix anything.Since the new data cable did nothing, and the drive worked externally, the most likely conclusion was that it's a problem with the logic board, which is next to the memory slots and probably somehow sustained damage through flexing or breaking of soldered connections when I struggled to get the non-functioning, too-thick, ill-fitting Corsair memory out.A logic board replacement is in the $500+ range, and I don't want to invest a lot more in my aging laptop, so I'm stuck with a computer that works only if the hard drive is in an external enclosure....not very handy, since my laptop now has the mobility profile of a desktop :(So all told, I ended up spending a significant amt of $ on 2x4GB of this Corsair memory, plus $100 on additional parts + $50 to buy memory that actually worked (OWC) and now I'm out $200 total and have a crippled computer...all because I bought this crappy memory. I suspect that the good 2010 Macbook reviews for this product come from people who (1) did not get a lemon in their memory order and (2) NEVER had to remove the Corsair memory after they installed it.Is it worth the risk to save $10 on Corsair vs. buying a more reputable brand? Your call, but based on my very unhappy experience, losing significant time investigating the problem and installing / uninstalling parts, wasting $, experiencing a lot of headache and gnashing of teeth, and also crippling my computer, I'd give that a big NO NO NO NO NO NO NO.If you have a 2010 Macbook Pro (or any similar model), AVOID THIS PRODUCT!!

I wish I had bought this sooner. I was running my mid 2009 Mac Book Pro on just the 2 gigs of ram it came with and it was starting to become a major source of stress. My Mac Book Pro holds a maximum of just 8 gigs of ram so I had planned on buying two of these 4 gig sticks but decided to just get one for now and try it out first. I had two, one gig sticks installed so I popped one out and and put the new four gig in its place, bringing me to a total of 5 gigs. Removal and installation is super easy, I think just about anyone can do it so save some money and do it yourself. There's plenty of guides on the Internet that will walk you through it, ifixit.com being the best. The 5 gig increase has worked wonders for me, so as soon as I order my second stick I'll be really zippin. 8 gigs max sounds silly considering the amounts of stock ram shipped with computers today but if 5 gigs has already worked great then the maximum of 8 that I can install will be fine and I even consider myself to be a "power user"

Okay for help with people understanding compatibility my macbook is A1342 13in White Polycarbonate 2.26ghz Intel C2D. I originally had the factory 2gb (2x1gb) i pulled them both out. Put the 4gb in the bottom slot and one of the 1gb in the top slot; i'll be buying another 4gb soon. And it is recommended that you have matching RAM for increased performance. But even so. From 2 to 5gb feels better especially loading apps. but being as yosemite is a little rough to run i plan on installing a SSD which is what i'd recommend to anyone looking to increase performance on an older macbook. Retina Display macs have flash storage so thats why they're still so snappy.

Works perfectly in upgrading our old 2010 Mini Mac - you don't need to get this in pairs! Our mac came with 2GBs with 1GB in each of the 2 slots. Removed one of the existing samsung 1GB memory sticks in the top slot(because it's the first and easiest to remove slot), and popped this Cosair 4GB SODIMM in, computer booted right up, recognized the memory and started using it right away. With the High Sierra OS upgrade, it was definitely running slow before, now it's almost like day 1.

I dont have alot of expierience with upgrading memory. I t was super easy to put it. I notice the computer runs hotter but not much. Its faster but not like upgrading in a PC . My PC'S were lightning fast my mac is a bit faster but has like a tank holding water capacity where the PC's never had this effect. I would suggest this memory to anyone it was dirt cheap compared to mac prices at 100 per 4 gig stick and it does its job. i just wonder if better grade memory would run faster as a whole ?

Just got two of these in the mail. Shipping was fast(Prime eligible). Popped them right into my Macbook Pro (Mid-2010) giving me 8gigs total. The computer recognized all of it right away and I'm good to go.Only thing I can mention to be careful with is taking them out of the packaging. Like others have said, not the best packing job. Not much for protection of being rattled around in the box while shipped and then when you are trying to remove from the plastic you feel as though you are going to snap the fragile RAM... just be gentle and pry it from the top.5 stars so far!

My 2009 MacBook Pro was continuously slow, with the wheel of death always spinning. I finally realized it had come with two 2gb memory cards installed. So, I ordered two of these 4gb (the most it will accept) cards and voila, it works beautifully! (Full disclosure: I also found the function where one can increase the amount of memory used for browsing, etc., and set it very high.) Either way, my laptop is moving at lightening speed and the memory cards are doing their job.

Dopo un mese di test mi accingo a recensire gli articoli che hanno dato nuova vita al mio macbook 13" di fine 2008. Scriverò le recensioni in modo che possano essere presi in considerazione per un upgrade di questo tipo su una macchina datata. In sintesi ho sostituito la batteria, incrementato la RAM, sostituito il vecchio e poco capiente disco rigido con un SSD e rimosso il SuperDrive per inserire un adattatore da 2,5" con unHD rigido da un TB; ho completato il tutto creando Fusion Drive dei due dischi e facendo un'installazione pulita di macOs el Capitan (recuperando i file importanti da TimeMachine) e infine abilitando TRIM per la gestione delle celle vuote del SSD. I prodotti sono: Batterytec® Batteria del computer portatile per MacBook 13 A1280 A1278 MB771 MB771*/A MB771J/A MB771LL/A [10.8V 45WH 12 mesi di garanzia ] voto 10/10. Arrivata nei tempi previsti da Amazon con un solo ciclo di carica(quindi nuova precaricata dalla casa produttrice) dopo un mese di utilizzo mi ha dimostrato un ottima tenuta con utilizzo intenso; che dire, per sostituire la batteria nativa del macbook(che dopo 8 anni si era gonfiata e diventata pericolosa) è di ottima qualità ed economica. Sono passato da 10 minuti di autonomia a 6 ore. Corsair CMSA4GX3M1A1066C7 Apple Mac Memoria da 4 GB (1x4 GB), DDR3, 1066 MHz, CL7, SODIMM, Certificata Apple  voto 10/10. Anche qui tutto perfetto da parte di Amazon. Packaging perfetto. RAM ovviamente nuova e sigillata. Ho sostituito i due blocchi presenti da 1GB (2GB totali) nativi con due Corsair da 4GB (8GB totali). Slancio in avanti notevole, contemporaneo utilizzo di programmi abbastanza pesanti senza problemi. Crucial MX300 SSD Interno da 275 GB, SATA da 2.5 Pollici - CT275MX300SSD1  voto 20/10 :) questa è stata la chicca di tutto l'upgrade. Non si può capire come cambia un mac con SSD finché non si prova. L'ho installata al posto del vecchio HD per sfruttare la SATA 3. E' il mio primo SSD quindi non posso essere utile in materia di raffronti con altri dischi solidi ma il mio mac è passato da 8 minuti in accensione a 35 secondi. Consigli a chi installa due dischi di creare il fusion drive(online si trovano molte guide ed è abbastanza semplice). Spedizione e packaging ottimi. Hitachi HTS541010A9E680 HDD 2,5", 1 TB, Nero  voto 10/10. Tutto perfetto. L'affidabilità Hitachi è una garanzia.

a questo prezzo e della corsair,è vero non dicono se sono compatibili con un MACBOOK PRO del 2009:PERFETTE,e sono le uniche di un marchio serio!!

Uso spesso programmi di grafica per lavoro, la scelta di avere più RAM per non avere rallentamenti (evitando il cosiddetto " collo di bottiglia") quando mi trovo ad avere più file od applicazioni aperte sul mio macbookpro del 2010 è stata quasi obbligata.SCEGLIERE QUELLA GIUSTAPer non sbagliare modello, consiglio vivamente di controllare le caratteristiche del tipo di RAM che monta il vostro portatile. (esiste anche una pagina sul sito Apple dove potete cercare il vostro modello e vi verrà scritto anche la "memoria massima" supportata)Innanzitutto dovrete scegliere la tipologia poichè differenti tipologie (ddr3,ddr4 ...) hanno diversi innesti. Per quanto riguarda la frequenza, potete optare di comprare massimo 2 banchi (non ne supporta di più perchè è double channel) con la stessa di quella che avete a bordo, oppure una con una frequenza maggiore (Mhz) purchè uno dei due moduli abbia la frequenza di base (in questo caso diventerebbe mono-channel)CONCLUSIONESono passato da 4 ad 8 gb ed ho notato la differenza . Spedizione arrivata il giorno dopo l'ordine, in buone condizioni. Pienamente soddisfatto.** ricordatevi di avere un cacciavite Torx T6 a portata di mano.

Ho acquistato questo banco di RAM per il mio Macbook 6,1 (Late 2009) confidando nella qualità che contraddistingue il marchio CORSAIR. Ho optato per il banco da 4GB in quanto non ero sicuro che il Macbook leggesse più di 4GB di memoria (prima ne avevo 3, 2+1). Momentaneamente ho lasciato la memoria da 4GB Corsair più quella da 2GB ed il pc legge senza problemi 6GB di RAM totali, quindi dovrebbe riuscire ad arrivare tranquillamente ad un massimo di 8GB. Non ho notato problemi di nessun tipo, anche se non ho fatto test approfonditi (ho sentito che con alcuni programmi ci potrebbero essere problemi montando più dei 4GB massimi previsti di fabbrica). Ho comunque notato un aumento delle prestazioni raddoppiando di fatto la memoria! Penso che sia un ottimo acquisto per chi volesse ringiovanire il proprio Macbook, magari abbinando l'aumento di memoria con un SSD e specie, se come me, avete aggiornato l'OS ad High Sierra!

Product works for my macbook 2009 unibody white. From 4 to 8gb upgraded successfully by removing the 8 screws on the back and replace the ram module easy.
