    Does anyone know if this RAM will work in the new Penryn iMacs?

    http://www.newegg.com/Product/Product.aspx?Item=N82E16820227251

    The specs appear to be correct but I have read a few threads on this forum in which this RAM did not appear to work on the penryn MBP and I was wondering if there could be issues with the penryn iMac also?

    I bought that exact same item from NewEgg for my new iMac (which hasn't arrived yet). While I can't say definitively that they will work (can't test for myself) they are the specs the new iMacs support. The problems you mention with the MBP's incompatibility is that the MBP use the older Santa Rosa chipset which only support 667 MHz RAM - not 800 MHz which these are and the new iMacs support.

    Technically I think the sticks you would take out of the iMac to replace with these from NewEgg would work in the MBP (in theory) - they would just get clocked down to 667 MHz - but it's always best to use something in-spec to ensure compatibility.

    Would you mind posting something here and/or at NewEgg once you get a chance to test it out?

    Sure thing. Coincidentally, those bastards at NewEgg suckered me into ordering ram prematurely. You see, the ram was originally priced at $79.99 with a $15 rebate that was good from 4/16/2008 till 4/30/2008. I was unaware they would simple reissue the same rebate with a new window of validity. This time around, though, they knocked $5 off the price (so my final price was $65 whereas if I had waited a day it would have been $60 - basically free shipping). I'm not bitter about it or anything, but just letting other people know their game. I guess NewEgg is trying to get rid of excess stock.

    BTW, I noticed that that current rebate requires the rebate submission to be postmarked within 12 days of purchase (including weekends). Not sure what was required for your rebate but you might want to check.

    I was actually thinking of pulling the trigger since reviews of other OCZ RAM for use in Macs appear to be good. The only issue was with the 800 MHz RAM in the MBP which only support 667 MHz RAM. Since the iMacs support the 800 MHz RAM I'm thinking it should be ok, however I would prefer to do the installation on the weekend and with this Sunday being Mother's Day, I not sure I'd get the chance and if I waited until the following weekend, I'd need to submit the rebate before I had a chance to test it.... so I guess I'll wait and order of next weekend.....assuming of course that it works in your machine.

    I finally got a free minute to unbox my iMac, and yes this RAM worked like a charm :cool:

    Sweet ^_^ I just ordered that and a new iMac 24" 3.06ghz today so I hope I have the same luck as you with it working. Thank you on the update! :D

    The only thing different about OCZ RAM and normal RAM is that OCZ RAM is GAEMING RAM.

    You'll get a higher percentile of L33T HAEDSH0TZ with it.

    You can even OVARCLOCK it.

    ^ ROFL.

    Unless you're talking about their high high end stuff, all their memory is JDEC standard and runs well in Macs. You can use pretty much anything that complies to JDEC standards in Intel Macs (Mac Pro and early (hot) FB-DIMMS not withstanding). DDR2 doesn't suffer from the high density, cheapo 4 layer, PCBs that caused problems when Macs were using SDRAM. Just stick to a name brand and it'll work just fine.

    is this for real?

    Why is this RAM (OCZ) HALF as much as what Crucial.com is recommending for the new iMacs??:confused: Is this the real deal?

    I just got one of the brand new 24" 2.8GHz Penryn iMacs and need to bump up my RAM. I'd be happy to spend more to avoid having my iMac explode. But if this OCZ RAM is the real deal, I don't want to throw my money away either, buying the same stuff for twice as much. If someone can tell me this isn't too good to be true, I'm'a pull the trigger right quick.

    What RAM have everybody else been sticking in their new iMacs???

    That OCZ RAM is CL5 and the Crucial RAM is CL6. The OCZ one should a wee bit faster, right?

    I bought the Apple RAM and didn't check which brand they put in.

    Though I'm no expert on whether Apple uses random RAM chips (like they do with hard drives), I pulled out two Samsung 1 GB sticks when replacing them.

    If you read this post a little further up, you'll see that I bought the exact same RAM that you linked to and that it worked. Probable reasons for premium price is that you'd be buying direct from the manufacturer (they tend to sell at the MSRP when most retail outlets will have to price it lower to stay competitive) and because Crucial can lean on their sterling reputation to charge more for RAM that will "just work".

    Just to clarify, I did read the entire thread and I linked to the same OCZ RAM that started the thread intentionally, for the sake of emphasis/clarity.

    It's not like I buy RAM everyday, but from my reading/experience I thought Crucial (despite the points you mentioned) was generally quite competetive in their pricing, albeit not the absolute cheapest. I have the impression that Newegg/OCZ are both reputable names as well. So the huge variance in pricing has me a bit puzzled and skeptical--despite your testimonial.

    But if you are saying your RAM is still "so far, so good" two days later, then I suppose I'll go ahead and make myself another guinea pig--unless someone posts something soon to stop me!

    From the specs the OCZ RAM be it cheaper is better, and if it does work like Enuratique says it does then it would be the preferred one to get. I ordered mine and now I just have to wait for it to arrive with my new iMac. I will also post an updated if it works or not if yall want. With comparable benchmarking scores.

    Good catch! I hadn't noticed the different CLs.

    So the OCZ is 1/2 the price and (possibly) a pinch faster. Sounds too good to be true!

    They're as competitive as they can be on the open market. You'll notice that NewEgg is a certified reseller of Crucial RAM. NewEgg, however, sells the same sticks Crucial does on their website but for $99.99 instead of the $129.99 at Crucial.com. That's what I mean by getting charged more simply by buying through the manufacturer instead a certified reseller/third party. They can get away with this because they have other revenue channels (the third party resellers) and know they can make a few extra bucks on the side from people who use their RAM compatibility tool to locate the kind of RAM they need and will just purchase right then and there. It's the same thing for HDTVs from Sony. Anecdotal evidence shows that buying a TV bought directly from Sony's website will cost $4,299.99 whereas getting it through Amazon.com will cost you $3,449.99.

    Also, I've never had a problem with RAM going bad within the first 3 years of ownership... It will either be bad from the outset (as a result of manufacturing defect) or it will last the life of the computer. So long as you get RAM that the iMac can support (eg: Unbuffered, Non-ECC, 1.8V 200-pin PC6400 DDR2 800 MHz SO-DIMMs with a CAS Latency of either 5 or 6) it should just work - I mean, that's how Crucial's compatibility tool works - they just get the supported specs from the manufacturer and it's a simple SQL command to retrieve their products that match those specs. I can't find the link to it offhand but the Apple website technical documentation for the latest iMac made mention that it only supports CAS Latencies of 5 or 6.

    Happy shopping!

    Thanks for the tip! Newegg has the Crucial sticks for $79.99 actually, after rebate. That's $50 cheaper. Dang!

    I tried the Crucial memory selector on Newegg and got zilch, so I didn't even think to look up the specific sticks. Looks like, with the exception of crucial.com, many sites haven't updated their "memory selector tool" databases yet to include the new iMac specs.

    Although the Crucial memory (via Newegg) isn't a bad deal, I guess based on everything (price, CL, your "they'll either be DOA or they'll last" principle) I'll try the OCZ. Thanks for the advice!:D

    (But I'm still curious what other people have been buying).

    I have some questions i hope they are not stupid.
    Everytime im about to order i get a bit scared. "is this the right Ram or not?". I need to put 2x 2gb in my new Imac. And i found the following i want to order.

    http://www.azerty.nl/producten/prod...5300cl5d-4gbsk-4096mb-667mhz-ddr2-pc5300.html

    I think this should be ok but it doesnt say SO-dimm but it is placed in that category. Does 200 pins always mean its SO-dimm?

    what does PC5300 mean? does that matter?

    sorry for all the questions. Maybe there are more people with these RAM questions that can learn from your answers.

    :apple:

    When in doubt, email the seller and ask.

    DDR2 Specification standards

    I noticed that the one you were looking at was 647hz and not 800hz. I don't know if I read it wrong, because I can't read the language it is in, but Mac RAM has to be 800mhz

    Yeah, the new iMacs (released late April of 2008) need PC6400 (800 MHz) RAM. The older iMacs (released August of 2007) can take the PC5300 (667 MHz) RAM.

    ^^ Which is completely the wrong RAM for Macs. Those are DIMMs, not SODIMMs. (Also good luck on the Tigerdirect mail-in rebates. TD are infamous for long or never rebate cheque arrival times.)

    I recommend you go with a reputable supplier who guarantees Mac compatibility.
