A-Tech for Apple 1GB DDR2 667MHz PC2-5300 200-pin SODIMM for MacBook, MacBook Pro, iMac, Mac Mini - (Early/Mid/Late 2006, Mid/Late 2007, Early 2008, Early 2009) - Memory RAM Module

Ram installed perfectly in my iMac, and so far my iMac is running much better. Still to early to do a full review but so far all is working great.

I needed memory for a finicky 2007 iMac and I knew A-tech was a brand I had successfully used before. Worked perfectly! I just needed to clean the contacts with an eraser as the memory was giving me the dreaded 3 beeps at first, after that it worked like a charm where other generic memory failed. Thank you A-tech!

Breathed new life into my 2007 MacBookPro. I had already performed surgery to install a SSD and noticed an improvement, but a software update really bogged the system down. I like the older OSX, but the newer was a must... so I needed to find a way to speed things up a little. Enter this RAM. I only opened and used the 4GB chip, as I already had 2x2GB installed. This was cheaper than getting the 4GB stand-alone. I instantly noticed some improvement. Still not as fast as it used to be... and honestly it's WAY past time I upgraded, but I'm attached, and hesitant to buy a new overpriced Apple that doesn't allow user upgrades. But this has postponed the inevitable just a bit longer to let me get every last bit of performance out of the old trusty machine. If you're looking to stretch every last bit of utility out of your old laptop, this is the way to go!

Bought two 2gb modules and they worked perfectly for my 2007 iMac. I was finally able to update the computer to El Capitan after being stuck with snow leopard for so long. All this just so I could download a printer driver from dell since their installation disk didn't offer Mac installment.

Added the ram into a 2007 Macbook, it ran great. Didnt need the Macbook anymore (got a newer one) so I gave it to a co-worker. He's enjoying his first Mac

Perfect match for my MacBook Pro laptop. Quality parts that do not over heat when used. Improved the speed of my photographic editing programs by 100%.

I currently purchased your product for my Imac because I was receiving the black screen of death. I went on line to get an answer to solve my problem. Of the several options listed one suggestion was to replace the old 4GB's ram on my computer. As of the result of replacing with new ram from A-Tech my Imac no longer receive black screen error.I would recommend this product to anyone to try to solve this specific issue.One last thing my computer runs faster than it did before.Thank you A-Tech

The customer service is excellent. I tried the 8GB first and had to return it because I was sent HP certified. The installation went in easy and the computer started right up. Memory showed the increased memory and the old bird was moving faster. Then, the temperature jumped to 183 degree and then went up and and up and up. It stayed at 188 degrees, which is crazy and then went up to 250 degrees. I am glad nothing was fried. I re-installed the old memory and it booted up (slowly as always).I did return the memory and chose another brand. The seller was very helpful. I think Macs, especially old ones are tricky and you have to try several out before you find one that fits.
