Installed in 2010 Mac Mini 10/12/2010 1:04:11 PM

Pros: Fast, Heatsinks

Cons: Expensive

Overall Review: These are a great match for the Mac Mini, the heatsinks help keep the RAM cool in the small case of the Mini. Unlike the previous reviewer, I didn't need to cut the edges of the heatsink off. Sure the side springs where the RAM clicks in stick out a bit, but nothing that would interfere with the case at all. Mac OS X 10.6.4 shows 4GB of 1067MHz DDR3. Works great.

Pros: Had this ram for a few days, and haven't had a single issue. I have seen a noticeable difference in benchmarks etc. My laptop automatically downclocks ram to DDR3 800, so this ram was a no brainer, since anything more than 1066 would be a waste, and with CAS latency 5, however...

Cons: It looks like CAS latency 5 is only possible with XMP which my processor doesn't support, my bios also doesn't let me change it manually, and it seems to default to CAS latency 6, so I'm not too bothered by it.

Overall Review: So far this ram seems to be very reliable. From what I've noticed with Kingston HyperX ram, the model numbers ending in GX are more reliable, maybe even revisions/replacements of the ones that end in G.

Works in the new 2010 Mac Mini 7/8/2010 7:38:11 AM

Pros: This was some of the fastest ram that I could find that was compatible with my new 2010 Mac Mini, and it works without problems.

Cons: The heatsink case was a little too big and I had to remove some of it around the sides of the ram. It only sticks out maybe an extra millimeter or two on the sides but it was just enough to get in the way of the casing.

Overall Review: Great product, even with my destruct-o mod I'm very pleased with this ram.
