Macbook A1342 RAM upgrade?

[sebu123]

Am I able to upgrade to a single PC3-12800 1600MHz 4GB RAM card, on a Macbook 1342 Mid-2010? 🙂

And can I run a 1066Mhz PC3-8500 RAM card, while running the PC3-12800 card?

Thanks in advance. 🙂

Won't work with only the PC12800 card

Will work with a PC8500 and PC12800 card

Some mid-2010 white MacBook Unibodies seem to run ok with PC10600 ram but to run a PC12800 card you will need a PC8500 card in the other slot - the PC12800 card will run at PC8500 speed......

Logana, can you clarify 'some' and 'seem to'?

I've recently acquired an A1342 with 2x2GB PC3-8500, and want to take it up to 8GB. Looking at online configurators, Crucial sticks by Apple's original '4GB max' whereas Kingston seems to deny the existence of the 2010 Macbook altogether.

Out of idle curiosity I have *just* tried fitting the 2x4GB PC3-10600/1333MHz from my Mini. The MacBook tells me to beep off.

If I want 2x4GB that is 'guaranteed' to work in an A1342, regardless of any secret little parts changes/tweaks that occurred during the production run, do I need to stick with PC3-8500/1066MHz?

EDIT: Dabs appear to have the right stuff, although I can't trace it back to Crucial's own website. Price looks about right in these expensive times (the Crucial 2x4GB kit for the Mini cost me £33.79 including VAT/shipping 22 months ago!). I guess there's no point looking at non PC3-8500 in an attempt to save a few quid...

some 2010 A1342 MacBooks have been reported as being quite happy with PC10600 ram but yours is obviously not one of them 🙂

It will work with at least one PC8500 module in it - the other module can be PC8500, PC10600 or PC12800 so you can save money by fitting one higher speed module since they are usually cheaper.

a 2GB PC8500 and a 4GB PC12800 will work fine....

Amazon have this http://www.amazon.co.uk/Corsair-CMSA8GX3M2A1066C7-1066Mhz-Certified-SODIMM/dp/B00505EZYW/ref=sr_1_8?ie=UTF8&qid=1397943343&sr=8-8&keywords=8GB+ddr3+pc8500 which seems to be perfect and at less than £60 must be a bargain (!!) I am guessing that Dab's price does not include delivery.

Yeah... as I was doing it I thought I should at least *try* mix'n'match, but didn't. I've got no idea if there are still benefits to paired RAM modules but I do intend to keep things symmetrical.

Thanks for the Amazon link, it does work out cheaper than Dabs + postage. But then... if I slipped another of their bargain Toshiba Canvios onto the order... postage would come down to £1.99... decisions decisions...
