Great memory and a great price!, Review by Piotr Golebiowski
Rating
I purchased this as a cheap upgrade to an aging Mac Pro (MacPro1,1) that my parents used. I haven't heard of this company before so I was a bit skeptical but I went ahead with the purchase anyway.
In the end, everything turned out great. The Mac has been running with the new memory for about 2-3 months now and so far there have been no issues. ***This review was posted on: http://www.amazon.com/product-reviews/B007PNAQZO*** (Posted on 12/06/2014)

4gb ram Review by Amazon Customer
Rating
It's ram.... so "I love it" may be a little too strong of a phrase, but 5 star rating is worthy of this product. It passed a full memory check with tech tool, no problemo. Seems to be working just fine in my 8 core mac tower which runs 24/7.

Passed 45 passes of MEMTEST 86+ Review by K. Yen
Rating
It works and cheap. Reward to risk is pretty high.

I have a few years old HP G5 server. These FB ECC DDR2 are not cheap normally. Komputerbay has it right price. I figure I lose $50 worst case. It has Komputerbay label and a Samsung label on the modules. I ran memtest on them for a week. It passed over 45 passes. As a result, I ordered 8x2GB from Komputerbay again. The 8x2GB modules has Hynix label on them. They also passed multiple memtest passes. I don't have reliability figures. ***This review was posted on: http://www.amazon.com/product-reviews/B007PNAQZO*** (Posted on 12/06/2014)

Works fine but not the first time Review by Jason
Rating
I read the reviews and I had teh same luck at first as a few of MAC pro desktop users with the memory not showing up. First time I placed 4 GB beside the 2 factory sticks of 512's on teh lower card and the other 4 GB on the upper and it only showed 5 GB.

Next I placed All 8 on teh top card and left the factory on the bottom and it worked. My mac pro was behind the power curve and needed the extra memory for speed and to upgrade to the newer OS thats available as well as I Tunes.

Its been in for a week and all is well.

As far as the high temps other people are reading. IMO you cant tell the heat accurately with the side cover off since the fan can no longer pull air across and through case thus cooling the sticks. ***This review was posted on: http://www.amazon.com/product-reviews/B007PNAQZO*** (Posted on 12/06/2014)

More than good enough, but be mindful of the merchant return policy Review by i_law38 "i_law28"
Rating
It has worked great so far. That is after 4GB of the 16GB refused to work. Considering the cost was negligible and the remaining 12GB have been excellent, although I would order I'd also carefully read the fine print. Komputerbay offers Lifetime replacement while Amazon however only offers a Full refund for the entire purchase returned. Temps are slightly higher than my older Ram as expected as more Ram would simply generate more heat. A solid buy that has survived endless hours of Video Editing, Movies and Music and with the Manufacture warranty I can't find many reasons not to buy. ***This review was posted on: http://www.amazon.com/product-reviews/B007PNAQZO*** (Posted on 12/06/2014)

Outstanding product Review by Rick C

I was playing with 4GB of RAM in my HP ProLiant server. While that was sufficient for my server's purpose, I desired to increase it. At the same time, I was afraid of the cost to bring my machine to 16GB. This steal of a deal was worth every penny. I am greatly appreciative for the opportunity this company has given me. ***This review was posted on: http://www.amazon.com/product-reviews/B007PNAQZO*** (Posted on 12/06/2014)

I was skeptical, mostly due to the price Review by K. Robert
Rating
These are so much cheaper than the Apple products and some of the reviews have been less than stellar, so I was a bit leery when I bought them how well they'd work. I bought 4 x 2GB sticks. Turns out, my concerns were unfounded. I have had them in my 2006 Mac Pro 1,1 for a couple of weeks now and there have been zero problems. I went from 2GB to 10GB & I'm loving it.

The key, apparently, is to make sure you install them in the correct place. You want to install your largest memory at the top of riser A first, then top of riser B, then bottom of riser A & bottom of riser B. So if you have 4 sticks of memory, you'll put 2 on riser A & 2 on riser B.

It's a good idea to try and even out the memory, too. For example, if you have 2 x 2GB sticks & 4 x 512MB sticks, you'd put your 2GB sticks in the front slots of riser A & all of the 512MB sticks on riser B. I'm assuming everyone knows that the sticks need to installed 2 by 2, so you would NEVER have 3 sticks on A riser & 3 sticks on B riser. ***This review was posted on: http://www.amazon.com/product-reviews/B007PNAQZO*** (Posted on 12/06/2014)

Worked for 9 days Review by poppaganda
Rating
I've had this memory installed for 9 days. Was an add-on to existing 8GB on 4 DIMMs. Today the internal fans spun up like crazy and the machine froze. Opened the case, rebooted and looked around at diagnostics. Sure enough temp on one of the DIMM cards was ~300 degrees for each DIMM. Should be around 110-120. Pulled the new DIMMS and everything went back to normal immediately. Very poor build quality and inferior components.

Install/Use 4GB RAM, Review by Eugene A. Hammel

Installation on an Intel Mac (desktop) was trouble-free. There are installation instructions at apple.com/support, specific to various models of the desktop Intel Mac (and of course other Macs).

My mistake Review by Dj

I ordered this RAM not fully realizing it was buffered RAM and it would not fit in my PC. I contacted the company thinking it was a mistake on their part, but no, it was my own fault. They got back to me quickly enough and were easy to work with. NO reason not to buy this product, just make sure you get the right type. MY manual for my motherboard did not mention that buffered RAM could not be used, and i ran into a problem because of this. ***This review was posted on: http://www.amazon.com/product-reviews/B007PNAQZO*** (Posted on 12/06/2014)

Not all of the RAM worked Review by NR
Rating
I purchased 20 gb of RAM for my Mac Pro - and I bought the 4gb modules. Unfortunately I believe at least one of the modules is bad and will not work. At first I installed all the RAM and the computer would not start up. Then I altered the positions of the new ram from Komputerbay, keeping them together in pairs, with the existing RAM I also wanted to use. The computer started up and worked OK but only for a few days. Then I started to get kernel panics. Right now I have removed one pair of the new RAM I bought from Komputerbay, and I am back up and running OK. I believe some of the RAM I purchased is not working so I will try to return it. I'd say buyer beware with this RAM. The price was low - but not all of what I was able to buy worked. ***This review was posted on: http://www.amazon.com/product-reviews/B007PNAQZO*** (Posted on 12/06/2014)

It works, but be warned. Review by Matt
Rating
While this RAM is cheap and works, it has a few drawbacks. I am currently using 8GB of this in my Mac Pro 1,1

The RAM runs very hot. The headsinks are not Apple certified, and feel very cheap. As I type this, my OWC 4GB (2x2gb) kit is at 118*F (closest to logic board, top riser), Nanya (2x512MB) is at 113-117*F (outside, bottom riser), and Komputer bay (4x2GB) is at 120-150*F (outside/inside bottom/top). This is at idle basically, any light usage temps go upwards of 160-170*F. I decided to take a peak at the Komputerbay RAM and took the heatspreader off only to find crappy plastic adhesive holding them to the RAM. The CPU on the chip was covered in a horrible crappy yellow thermal paste not actually on the die, but all over the outside of the die. Also, there was a massive glob of thermal paste on the heatsink that was larger than the actual chip. Waaaay too much.

For one set I used the existing heatsinks and another set using an old set of Nanya heatspreaders (with fabric pads and oil). I removed all the excess gunk from the RAM using 90%+ isopropyl and gently applied a very thin layer of Arctic Silver 5 thermal paste to each memory chip (there are lots!) as well as the CPU. Then, I put everything back together and popped it into my computer. Here are the results:
*Note: RAM closest to the Logic Board tends to run hotter than those toward the outside

117*F --> Komputerbay RAM with Nanya heatspreaders and Arctic Silver 5 (A3) [was 128*F]

126*F --> Komputerbay RAM with stock heatspreader, no Arctic Silver 5 (A4) [no change]

144*F --> Komputerbay RAM with stock heatspreader, Arctic Silver 5 (B1) [was 152*F]

Replacing the heatsinks and thermal paste shaved off quite a few degrees...but at this point you might as well buy better RAM.

While this stuff works, just be ready for your fans to be on more frequently as well as more heat, unless you use smcFancontrol or something. ***This review was posted on: http://www.amazon.com/product-reviews/B007PNAQZO*** (Posted on 12/06/2014)
