Pros: Looks cool

Cons: This memory is not stable, I have tried every possible way of tweaking it into running at 1600mhz with a ASUS M4A79T Deluxe. Its currently running at 667mhz... yes... 667mhz. It crashes my system if I go any higher than 1.60v.

Other Thoughts: Probably going to RMA this and go with a company with a better reputation.

Pros: cool blue color heatsink. Cheap.

Cons: Memory is causing reboots, errors, freezing, drove me nuts. Does not run stably at rated settings and will NOT run at any voltage higher then 1.7 ...which is odd considering Kingston says right on their site that it runs at 1600Mhz @ 9-9-9-27 and 1.9 volts. Im loosing if not lost my confidence in Kingston's quality :(

Other Thoughts: I suggest another brand.

Pros: Runs at the rated speed of 1600mhz at 9-9-9-27 and 1.5volts in my M4A79T Deluxe in combo with Phenom II 810. Price is really cheap for such fast DDR3.

Cons: Takes overclocking of your cpu to make this ram run at the rated 1600mhz. Though I had intended to do this anyway. Wish CAS was lower but no biggy.

Other Thoughts: This ram is intended for overclockers, dont expect to achieve 1600mhz speeds without some BIOS fiddling.

Pros: See my comments from previous. Installed on an MSI 790FX-GD70 with no problems. Board automatically set it to 1333MHz but set to the advertised timings and speed and the memory is running at 1600MHz. Been playing with this memory and the lowest stable latencies I've acheived are 7-7-6-15 at 1667MHz. Not bad for a memory design that's been out since late last summer.

Cons: None.

Other Thoughts: The heat spreaders are very thoughtfully designed. You'll see what I mean when you have them in hand.

Pros: Just ordered this on a combo offer with an MSI 790FX-GD70 that offered a $20.00 discount. Considering that I was initially looking at another manufacturer's 2x2GB kit with tighter timings at $125.00 I ended up saving a total of $65.00 by going with this memory. The timings aren't as tight but that's OK when considering the savings. I'm going from DDR2 800 2x1GB so I will see a noticeable upside in memory performance.

Cons: None, haven't received yet.

Other Thoughts: I'll post later on how it goes with the installing on this mobo.

Pros: One stick worked, and it was able to run at multiple timings and voltages,

it works... half the time.

Cons: The ram will not stay stable when clocked to it's described 1600 mhz. I had to crank voltages in order for it to boot into windows. Currently my ram is set to the factory 1057 mhz, so I can write this review.

Other Thoughts: Granted, One stick is bad because of errors in memtest, but the amount of tweaking to find a setting that the ram was able to handle, was annoying. I currently using another set of ram while the kingston ram is RMA.

I'm very disappointed in kingston and their quality. I would NEVER buy again.

Pros: Great Memory would be an understatement. Easily OCable and stays relatively cool even during heavy work loads and very powerful. Running 8 gigs of this with my ASUS PRO WiFi LGA 775 NVIDIA nForce 790i Ultra SLI and with x2 XFX 9800gtx XXX 740 edition, couldnt be more content. Buy it now before it goes back up to $500

Cons: None until it goes back up to $500

Other Thoughts: Q9450 oc @ 3.8ghz/ ZALMAN|CNPS 9700 NT R/ x2 300gb velociraptor/x2 xfx9800 gtx512 oc780/ SAMSUNG ToC T220 Rose-Black 22""/ Thermaltake ArmorPlus(Armor+)/ ASUS PRO WiFi LGA 775 NVIDIA nForce 790i Ultra SLI ATX Intel/ Kingston HyperX 8GB (4 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)

Make sure you have good cooling and lots of room to work with.

Pros: Would just like to let everyone know I went out on a limb and payed too much for a name brand memory, but sometimes the money you spend is money well spent. This memory is just that. It oc's amazingly well and stay nice and cool for its performance. Running it on a evga 790i Ultra.

Cons: None

Other Thoughts: I got it on sale otherwise there would be no way I would pay 500 dollars for memory. I upgraded from some 100.00 1333 corsair xms memory to this and could not be happier. If you have the money spend it on this memory if not look for a alternative brand.
