Good, fast memory...
operating system:Other...as long as you're familiar with your BIOS. The SPD on these modules is programmed with the settings for 1.8V operation, at which settings it will run at PC2-6400 speed. It needs 2.2V VDIMM, the tRA/tRD/tRAS lowering to 15 (from 18 in the SPD) and DIMM clock raising manually to run at PC2-8500 spec. This is not to be taken as a criticism, just be aware that this needs special care when wanting to run at PC2-8500 spec.
Also, Phenom AM2+ processors (I suspect this includes the Kuma (Athlon X2 7750+ BE) core, but don't quote me on this - this IS a processor limitation as the memory controller is embedded in AMD parts) can only handle one 1066 DIMM per channel; this means if you have a board with 4 slots and an 8GB limit, you'll only be able to use the two slots that give you ganged 128bit mode. It'll refuse to boot if you put them both on the same 64 bit controller of try to install 4 modules. In summary, at PC2-8500, limit of two modules maximum, one on each 64bit channel.
OS is FreeBSD7-STABLE amd64 (currently ID'd as 7.2-PRERELEASE) and this works on the Asus M3A78 Pro with a Phenom 9950BE.

Good Good
operating system:Windows VistaBought these sticks to run along side a Intel Quad core Q6600. They really do the job some people don't quite understand that speed is important this RAM comes with the ability to go as high as 1066MHz but when you install them the BIOS will set them to 800MHz so you have to change that in your BIOS.
To make people understand better like I have said above these sticks can run at 1066MHz and my Proccessor can also run at 1066MHz. They liked to be coupled so you can get the best results in performance. I have seen this happen with people but they buy an awesome processor that has a FSB 1333 and then buy RAM that runs at 800MHz now these two components like to run side by side but with these two it means you are wasting performance and losing money because of it so when it comes to purchasing RAM or Processors make sure you can get them to run along side each other.
E.g Intel Quad Core Q6600 runs at 1066MHz
Kingston 2X2GB of RAM runs at 1066 Mhz these will run in harmony together.
Thanks Ebuyer
Excellent Value For The Price
operating system:Windows XPI ordered these on monday for a thursday deliver but they arrived a day early (thanks ebuyer).
Got mine at stock speeds at 2.1v I'm using a AMD 9550 Quad Core CPU, Gigabyte GA-MA78G DS3H AM2+ board. I'm running it also in unganged mode 64bit per channel as give better performance so what I've read on my local computer forums.
I say I'm running XP 32bit thats because I had some OCZ Reaper 2GB DDR2 but sold it and left the op system on. If it wasn't for a huge project I have to do this weekend I would be installing the release candiate of Windows 7 64bit which I will next week via dual boot.
Spot on
operating system:LinuxGot some of this on Saturday for a new build PC - confirmed you DO NEED TO change the voltage and speed manually to get the 1066Mhz
other than that cant fault it!
