The over-all size of the memory module is just as important to the fit in the memory slot as the asymmetrical "key" slot.

I do not agree. To know for sure we would have to have access to the standard specifications, which we do not. However, no part of the SO-DIMM outside of the circular edge notches touch the socket, so I don't think that matters so much. Also, the physical size of these parts is highly standardized and the manufacturers know what they are doing.

I don't think I have ever seen a thread where so much effort was expended to avoid the truth. First, Sam Spade would not post pictures, and then fotofan went out of his way to obfuscate the issue by rotating and arranging the parts so the important sides were not only opposite each other but were reversed.
 
since OP wont post pics and there seems to be a lot of confusion i took some pics of my Crucial ram that i bought from Amazon. The part number and all that is in the pics.

hope this clears some confusion

I'm not wasting any more time on here. I was just trying to help alert people to a problem.The RAM I bought is "United States", not China made, as I specifically stated as being the problem based on previous threads I've read. So the sizing error seems to be specific to that run of RAM.
It wouldn't fit. I tried it!!!!!! What is wrong withsome of the people on here? Do you think I work for a competitor? Or are Sam and I the same person? What other ridiculous statements will you deniers say next? Perhaps you work for Crucial, since more finger pointing and innuendo will be coming soon.
Have fun trashing the next guy that tries to alert the community here. Aparently this place is just full of rude posters who like to think they are smarter than the next guy.
I actually took the time to take a picture because nobody believed Sam, and now my clear picture proves nothing? I'm sorry I flipped it the wrong way, but the RAM is on rectangular sheets. If the top is too big, so is the bottom, geniuses. Or are you know it alls telling me the RAM is tapered? Show me a tapered RAM stick. Go ahead, I'll wait for your pictures.
By the way, Crucial won't admit a problem. I'm returning and getting the OWC RAM. Which is now more expensive two weeks later. WIll not be buying from Crucial again, and I suggest anyone that wants good customer service and properly sized RAM does the same. Thank you Sam for taking the time to post.
Now flame away boys (as in little children), but I'm outta here.

Your picture suggests otherwise.


OK Helen.
Maybe a bigger picture will help you? Click on it to enlarge.
It is likely that yellow edge that kept it from seating. Regardless, it wouldn't seat and they were both the same. Just a bad batch, I suspect.

Just ordered from OWC. It was $199 now for the 8x2 RAM pair. That's $20 more than they were charging two weeks ago. I guess there are a lot of people upgrading their new macs. It won't break the bank, but I also have to take the time and money to ship the Crucial memory back and wait on the refund as well. Pretty annoyed right now.

Thank you for providing useful information. Nobody else has. Just unhelpful pictures and accusations in the rest of the thread.

That extra MM on the top doesn't affect fitmit. I compared my china ones to the oem ones and it looked just like yours. Yet it fit just fine in my 2013 I7 Imac.

If you look at the bottom of this picture II BISTRO II posted you will see on the bottom they its also extended. Just because the casing is extended by 1-2mm does not mean that it doesn't fit. Apple could have made it 1-2mm shorter because they preferred to let it wiggle around some. If anything Crucail ram is better since it's a Very snug fit. Meaning it wont move around.

Pay what you want, but their is a reason OWC ram is increasing in price and Crucial isn't. Thats because OWC monitors these forums and see the discrepancies between ran and takes advantage of users by increasing the price. They might even be posting in the thread false information like the op did without "Proof".

Mine was 1-2mm longer than the oem ram yet it fit just fine and works just fine, II BISTRO II also agree's since hes using the same ram as well. If you want to spend $60 more for 16gb and $120 more for 32Gig's feel free to. Just dont post on here saying the ram is defective because its a little longer. That just means Crucial designed it to fill the slot and apple didnt. Their hasn't been one photo of anyone destroying their 2013 let alone 2012 imac from crucial ram like the op "falsely" said that was an apples fault when he either doesn't own a 27imac or installed his ram incorrectly and destroyed it and supposably had apple fix it. The reason i say supposably is that i had my friend who works for apple search through the 2013 imac repairs inventory to see if any 27's had broken ram slots. He told me that he couldn't find 1 27 imac that got repaired for broken ram slots "Soft slots" in the USA for that issue.

I'll enjoy that extra cash to take my Wife out on a nice date. Fill my tank, Watch a movie with $$ still left over.

The op obviously supports OWC over other-brands whether its officially supported or not. Yet he supposedly bought crucial ram that was bad and destroyed his new imac.

Officially supported or not, I imagine if OWC is doing it, it works!

The few dollars difference between Crucial and OWC isn't really that big a deal when installing in a ~$4K desktop, is it?

In retrospect, I wish I'd have spent the extra couple of hundred dollars on Apple's factory installed 32GB to save myself the hassle of exchanging Crucial for OWC RAM.

The Crucial (which I bought direct from Crucial) was obviously slightly out of spec. End of story.

Exactly! If your already spending 4k pay for apple to upgrade the ram unless you "Truly" know what your doing. Just because apple has a ram slot doesnt mean that your every day "human" can handle the job. Crucial is not out of spec. Works fine for me and thousands of others. II BISTRO II's photos of the crucial ram fit 100% perfectly in the slot and even shows the 1-2mm increase in size yet they still fit just fine. If needed I'll be happy to snap some of the sam pics and upload them as well for more proof that Crucial is fine, but If you have any doubt! Stick to APPLE Ram only. You never know, you might just get crucial ram as oem too.

Sigh. It's specific to the United States memory. Yours is made in China. Don't you see United States on mine? Do you also see that extra piece of yellow on my stick of RAM? That is probably what kept it from fitting properly. I'm not about to jam it in there when it clearly isn't sliding into my new $3000 imac without great force. Crucial didn't "make it to fill the slot". They appear to have left a piece on the side of the memory they sold me that is keeping it from fitting.
So I'm glad yours fit. But it isn't the same as mine. And no need to be so arrogant.

The OWC ram I received was the exact same as Apple OEM. Both made by Hynix. I'm guess that is the price discrepancy.

It's no use Ephern. There's fit, so obviously everybody's should fit and we can't manage to fit a stick of memory in a slot. I'll not be ordering from Crucial again either. The OWC RAM will fit like the Hynix RAM Apple installed, so in the end this is all just a minor annoyance. As I said, $40 is not a big deal (and it certainly won't pay for dinner for two at a decent restaurant!), but it was only a $20 difference when I first ordered from Crucial.
Do you remember if yours was United States made? That seems to be the difference here.

Yeah, let me waste more of my time pulling the RAM out of the back of my computer and the Crucial RAM that is already packaged for return and take a bunch of pictures so I can prove myself to the likes of you and the rest of the rude posters on here. Take my advice or don't. I really don't care. What part of "it didn't fit" don't you understand? And do you not see the extra piece of yellow on that stick that clearly shouldn't be there? Click on it and look very closely at the enlarged picture before you post your nonsense.
I try to help out and get put on trial by the Crucial fan club. What a bunch of clowns around here. Done for real this time. Solved my problem, you do as you please.
 
It may or may not prove something to you.

It DOES illustrate a sizing discrepancy between the two parts.

The over-all size of the memory module is just as important to the fit in the memory slot as the asymmetrical "key" slot.

If you're not aware of that aspect, then you should not be handling memory modules or attempting to install them.

Facepalm
 
I actually took the time to take a picture because nobody believed Sam, and now my clear picture proves nothing? I'm sorry I flipped it the wrong way, but the RAM is on rectangular sheets. If the top is too big, so is the bottom, geniuses.

Here's a crop of your picture. I have added a red line along the top of the connector as you can see. The red line is perfectly parallel to the left hand side of the connector, left of the notch. If you pixel peep you can *just* see the edge of the connector above the the red line, so you can see that the red line is *perfectly* aligned.

Now look at the right hand side of the connector, right of the notch. It is plainly obvious where the size discrepency is.

The statement "If the top is too big, so is the bottom, geniuses", is perhaps somewhat ironic.

So you and Sam the thread starter seem to be lying. Where's the picture showing how the Crucial "doesn't fit"? Get out and stay out. Thanks Bistro and others. I'll buy the Crucial since it's cheaper and fits.

Never ceases to amuse me when non-moderators tell people to get out or stop talking. Hilarious.

Some Crucial-labeled RAM, distributed by Crucial and Amazon, fits very poorly. You can force the stuff in and it functions, but it's a poor fit.

Also hilarious: "since it's cheaper" being a viable reason in an Apple product forum! Steve Jobs would... never mind. :D
 
Why is it so hard to believe that there might just be a batch of RAM that is slightly out of spec? I get why folks here get their shackles up when someone accuses Apple (rightly or wrongly) of screwing up, but Crucial? Really?

You mean "hackles" not "shackles". Anyway, it's hard to believe because these things are made in huge volumes on highly automated equipment built and maintained to exacting standards.

Haha good catch! This proves the ram fit! The top part being an extra MM makes no difference. I thought II BISTRO II ram was also longer but he replied and told it was it wasnt even and i seen that afterwords.

So, that means so far no one has provided proof out of spec ram (the top being an extra 1-2mm makes no difference its the bottom that matters. SAM Failed to provide proof that his ram DAMAGED his IMAC since he failed to provide proof of the extended ram. If he even owns an imac i bet he installed the ram with the top piece 1-2mm longer and just assumed it was made incorrect and after he damaged his imac by USER ERROR he blamed it on the ram.

Why is it so hard to believe that there might just be a batch of RAM that is slightly out of spec? I get why folks here get their shackles up when someone accuses Apple (rightly or wrongly) of screwing up, but Crucial? Really?

It's because proof hasn't been provided. All its been is hearsay and when all you get is hearsay people wont believe a word that comes out of those peoples mouths. If the op provided pic of the "SOFT" ram slots things thread could have gone another way, but no one believe's him that APPLE would make their $2000-$3000 computer with soft plastic. Let alone the 2012 model has been out for over a year and this NEVER happened to anyone else. Until a picture shows up of the IMAC with Soft Smashed ram slots (Not Broken in Pieces) then i might believe them. Apple has quality control which is why that didn't happen with the exact same 2012 design models (just different processors).

The other pics that were provided have been proven false Chippy 99 did a good job at that. So I've yet to see any proof that Crucial is out of spec, or that Apple created "Soft" Imac slots. I can also repeat your question,

Why is it so hard to believe that these two people didn't create this thread to help sell OWC ram for their own company, or paid to do this? OWC knows that the new imac's are out and have user adjustable slots so the best way to sell them is to make sure Imac owners conclude that the ram from Crucail might screw up their $3000 imac making user spend an extra $120 for the same ram. Without Proof it can go both ways on your question and mine. I'm not saying they do work for OWC but without proof their is no reason to NOT assume this after a thread like this.

Hey now! I've worked for the same midwest consulting company for the past 11 years, and our business is large VMware ESXi installations, gigantic SANs and such things. There are some Macs in the company, but that's mostly the sales guys - there's just too much Windows specific stuff we have to run to bother with OS X.

In other words, there's nothing in it for me to tell you that either the (some batches of) Crucial RAM or (some batches of) Apple's slot is of a different spec.

I don't care whether it's the fault of Apple or Crucial. It's just a fact.

For all we know, OWC could ship out some Micron RAM that's also out of spec.

Fanboys... Sheesh.

I never said that they couldn't be out of spec. I've just yet to see any TRUE proof that their really is Crucial ram out of spec. At least 1 person posted photos, but the only part out of spec was the extra yellow piece at the top which only affects the amount of air space it takes instead of the amount of space in the slot since the bottom was in spec. I'm an unbiased party when it comes to this. I have argued both sides about crucial ram not working in the 2013 models ext... but then i was proved wrong when i tested it myself and it worked. It may seem like i'm taking crucial side, but I'm really just taking the side of the opposite of the op because It bothered me and many others that he would come on here making BIG accusations at crucial and Apple without providing one shed of proof. Then he comes back and says apple fixed his computer. He was either full of it, or apple employee's who accepted his computer felt bad that he destroyed is new apple computer because of is own "user" error. I worked in computer repair before and you wouldn't believe the excuses people made for destroying their own property and blaming it on the manufacture. Untill proof pops up i wont believe otherwise. This is just like people not believing in aliens until proof shows up. Same thing here. Until it shows up, I'll keep on believe that the op was incapable of installing ram correctly.
