    so you put the old ram back in and it still doesn't work?  Also, your macbook can only accept a maximum of 6gb of ram.

    To get your total 8GBs, did you install two *identical* 4GB RAM boards? I mean, from the same manufacturer, same everything? If not, un-identical boards, from maybe 2 different companies, *could* be the cause of your problem.

    And you have of course tried removing & reinserting both RAM boards, correct?

     

    Need more info from you..... Same exact 4GB boards, same mfgr?

     

    FYI, here are the two 4GB boards I got for my own 7,1 Macbook 1 year ago this month thru Amazon:

    Amazon.com: "Crucial CT2CP51264BC1067 8GB 204-PIN PC3-8500 SODIMM DDR3 (4GBx2)"

    For just $37 bucks, you can get a top-quality matching pair of 4GB RAM boards.

     

    Your Mac is a 6,1 and contrary to what shldr2thewheel says....

    .....your 6,1 Macbook *CAN* handle 8GB of RAM. The mid-2010 Macbook 7,1 like my own can, the late-2009 Macbook 6,1 like your own can, but the next one preceding it, the mid-2009 5,2 cannot.  6GBs max for that 5,2 all the way down to the late-2007 3,1 Macbook. All those, 6Gigs max. The 7,1 & 6,1, 8Gigs max. No matter what Crucial's RAM Scanner says, either.

     

    Here's a screenshot of my own Mac's RAM readouts that I took just tonight, at Crucial's own system scanner, the company that I bought the 8Gigs of RAM from that at their RAM scanner site the Crucial company itself does not acknowledge as possible:

    Here's a screenshot of my Mac's System Profiler info regarding my own Mac's RAM:

    So looking forward to reading in your next post what you've done next, & just what exactly those two RAM boards are / where they came from / manufacturer & model #'s / etc......

    Hi,

     

    It happened to my MacBook and iMac a while ago, after trying to put a new RAM, it sounded "bip" so I try to put the old RAM back. But then for some reason didn't work and producing "bip" instead!

     

    Have you solved this issue and what is the solution?

     

    Do you have 8GB on your MacBook now? What is your MacBook series?

     

    Thanks.

    Sounds like static electricity buildup in you two guyz's bodies zapped something inside your Macs.


    That's the most obvious cause, since you mention no anomalies in your fixit processes, but the cause for the failures could be something else though probably it was in fact static zapping or static buildup that fried a CMOS or whatnot. 


    It's said that the *only* way one should work inside a computer is with a static wrist strap on. But what I've always done, and never with any bad consequences, is to do work on my open Macbooks (and Windows PCs, back in my 80286 & 386 days when my good sense had somehow gotten shanghaied by The Dark Side) with the idea of eliminating and avoiding at all costs all static electricity.


    First, I do NOT stand on ANY kind of carpeting WHATSOEVER.  Linoleum-type floor only.


    Secondly, I do the work as close to a sink or whatever has water pipes & running water as possible.


    Third, immediately before the actual "surgery," I turn on cold running water & run my hands under the water, grabbing hold of the faucet/water pipe too, with both hands.  THAT discharges any static to ground & makes my body electrically neutral. And then I dry my hands with paper towels, not any kind of fabric towel. Perhaps overkill, but using a paper towel I'll know that by that point that I've done all I could do to eliminate body static electricity, short of using a wriststrap. 


    And it goes without saying, although most folks would probably not consider this, that a computer guts prober should do their computer surgery AWAY from any air cleaners that ionize or inject ozone into the air, even in adjacent rooms, and *certainly* don't do your laptop or desktop computer guts work with one of those things running nearby you.
