I was a bit wary about the cheap price of this memory when I first saw it, and considering I was planning to use it in servers running 24x7 I was even more cautious - it had to be reliable. Anyone using DDR2 Fully Buffered ECC RAM will tell you that it can run hot which can stress good memory, never mind cheap memory, but the price was compelling enough to make me give it a try.

I ran Memtest+ on every single module of memory I've purchased, running the test continuously for at least 36 hours - and sometimes up to 96 hours - to give the memory a really good workout. Every single module has come through the testing without a single error - an excellent pass rate.

I've heard all the usual rumours about it being cheap, reject, memory from bargain basement bins around the world, but my own experience tells me it is good quality.

We now have 160GB of this ram in production servers (that's 80 2GB modules) and it's all performing without a hitch. The servers they are installed in are hard-working and under stress 24 hours of every day without rest. The memory hasn't let me down yet and it's been over a 8 months since I first tried this memory out.

This memory worked perfectly for my 2008 Mac Pro. The customer service was outstanding (I originally ordered the wrong memory by mistake, and they fixed it for me), and the installation was easy. It works perfectly...nothing more to say!

Avoid like the plague. Two FB-DIMMs were dead & my 2008 Mac Pro wouldn't even boot with them installed. The other two FB-DIMMs were recognised as 2GB 667MHz not the 4GB 800MHz I had paid for. It was a tortuous process to get a refund & I eventually had to invoke an A-to-z Guarantee Claim from Amazon to force them to refund me. All in all it took about 4 weeks to get my money back.

I have just received this item (5/04/15) and straight away with just looking at the memory in the box (clear plastic ) you can tell it is NOT NEW! The heatsinks are covered in scratches and dints, the little silver clips that hold the heatsinks on you can clearly see are covered in grubby finger prints. Next you look at the gold contacts and you can see the wear and tear where they have been inserted and removed into the slots over the years. That being said if it works fine, then with the cheap price (60 quid for 16Gb) it is ok but I would have liked to have been informed if I am purchasing reconditioned memory (which this blatantly is) . On each stick of ram it says "Lifetime Warranty" with Komputer Bay but as I am come to learn over the year Lifetime has a different meaning in the world of computing. I have attached an image to show the scratches and marks etc, and to clarify I have not even opened these yet.

The racks of ram arrived ON TIME & very securely packaged. Because I had read some horror stories I put the ram in in stages and watched the G5 boot up with increasing ram comtent. All worked well. When all the new ram was in I was down by 2 gig I think. I pulled a tray out again - its really easy,
and sure enough I had not seated one rack correctly. All works fine now. Not massively fast bacause its old kit, but no bottlenecks when we have 4 apps running in the background. Would recommend the supplier-- the ram seems totally compatible.

Bought for an office machine and still running great (have bought several komputerbay kits in the past). One stick I bought from this seller was faulty but they happily refunded and with speed. So I can recommend the parts and the seller.

This is a niche product - but for users of old Mac Pro computers like myself, a vital upgrade that delivers noticeable results.
Absolutely spot on despatch and delivery, good packaging and excellent product. In a 2006 MacPro installed as matched pairs on each riser card.
It's the last gasp for this Mac but I'll seek out Komputerbay for other future upgrades.

Unfortunately these memory cards did not fit my computer's motherboard - the locating slot was about 3mm adrift from the pin in the slots, so was unable to use and they had to be returned (at my cost) for credit on 2/10/15. (At the time of writing this - 23/10/15, no credit has been received)
