Memory Upgarde for 2010 MacMini

Hi folks,

I tried to put the 2x G.Skill 4GB DDR3 PC3-1066 RAMs to my 2010 MacMini. It only kept beeping after reboot. Anybody has the same problem? Would anyone please tell me what brand of RAM. Thank you!

MacMini, Mac OS X (10.6.4)

Having this exact same error with my 2010 Mac Mini Server.

Updated the firmware, and checked for any software updates before starting this process.

Tried to replace the 2 x 2GB memory modules with 2 x 4GB memory sticks.
Upon restart the Mini just beeps at me.

So. . .

Removed the NEW memory and reseated. Once again upon restart it still just beeps at me. I then removed the new memory all together and replaced the original memory that put me back at 4GB using both slot 0 and slot 1. The Mini works as before.

SO. . .

Removed all memory, insert 1 stick of the 4GB memory. Mini restarts and sees the 4GB stick in slot 0, and says memory is OK.

Removed the memory stick in slot 0 and replaced with the other 4GB stick. Mini restarts and sees the 4GB stick in slot 0, and says memory is OK.

Now. . .

Placed the first 4GM memory stick in Slot 1 and kept the second 4GB memory stick in Slot 0. Upon restart the Mini just beeps at me.

NERD RAGE ENSUES!!!!!1!1!

Any help would be greatly appreciated!

Have you tried a single stick in Slot 1...?

With my non-working 8GB Kingston memory configuration in the Mac mini 2010, both 4GB sticks failed to work in Slot 0 (individually) and so I contacted Kingston but they were uncertain as to why it was failing.

The 1GB working factory sticks and the 4GB Kingston sticks both use Hynix chips but the component codes are different (factory - H5TQ1G83TFR, Kingston - H5TQ2G83BFR).

Calsifer,

When I first spoke with Kingston they were under the impression the Hynix chips were the same (exact H5TQ.... codes) but having realised they are different they are now raising the issue with their technical team in the US.

You might want to check your memory stick codes and if they are similar to the ones I've mentioned in my previous post you might want to get in touch with your memory brand's technical support and suggest Kingston are making further investigations.

Hynix have a code interpreter for ram modules on their website and it would seem the difference in codes means that a different Die Generation and chip configuration was used to the new modules from those that worked from factory.

Hope some of this helps you out.

Ran into serious troubles when trying to upgrade my Late 2009 Mac Mini (3.1) 2.66 GHz from the original 4GB to 8GB with Kingston memory KTA-MB1066K2/8G. No boot, just beeps. Then, after consulting Kingston tech support I reset the PRAM and NVRAM, see http://support.apple.com/kb/ht1379. After that I inserted the new 2*4GB RAM and now it works like a charm! (Thank you Kingston). I see that other users say that one should stay away from Kingston memories, but the reset maybe is all that it takes?

Hi MacValley,
I was about to purchase the same memory upgrade from Kingston KTA-MB1066K2/8G, when I noticed it is (according to Kingston) the same memory as the Macbook Pro, so I've found this discussion. Anyway, can you confirm the you reset the PRAM/NVRAM BEFORE you inserted the new ram? And then it worked and shows the full 8GB?

I went for broke with an 8Gig upgrade fom Crucial. Put them in and just go the beeps. Took one 4Gig out and replaced it original 1Gig and it worked. Did the VROM thing mentioned further down the thread where you boot whilst pressing option-command-p-r and wait for two start up noises. Then put the other 4Gig in and I'm "cooking with gas" on 8Gig.

I reckon you can only do so much per step with the PROM VROM thingy.

Thanks for providing info in this thread. I too bought the Kingston KTA-MB1066K2/8G. I tried to install it in my MM (2010 Unibody) and had the same results as you fine folks. Having the 4GB Dimm in slot 0 resulted in a singular beep indicating no ram detected.

I tried calling Kingston Tech Support and they told me that they had no record in their DB of issues with this RAM and the MM Unibody. I was going to call AppleCare, but decided to take the Cruical 8GB (2x4GB) RAM from my MBP 13" and swap it out.

Lo and behold, the Crucial RAM works in the MM and the Kingston RAM works in the MBP.

Although I did the research prior to purchase, I neglected to check the forums here. I learned a good lesson. 🙂

Happy New Year!
