Most PC users are familiar with the 4GB system memory limitation of 32-bit Windows Operating Systems, which is why 64-bit computing has become the standard for computer enthusiasts. Occasionally though, a computer system will not report the correct amount of RAM installed. In this article, our 64-bit Windows 7 test system had 6.00 GB of installed memory but indicates only 4.00 GB usable RAM available. While some may dismiss this as a case of defective RAM, you might be surprised by the culprit. Benchmark Reviews troubleshoots Installed Memory vs RAM Usable by Windows.

The need of USB hubs on the market is rising, because we are using more and more USB hardware devices like USB flash drives, USB external sound cards, printers, 5.1 headphones and the list could continue. ROCCAT have developed a very nice looking USB hub with an integrated mouse bungee, that holds the mouse cable for you and this way it will not get in your way when you game.

In the world of mechanical hard drives, the new 6Gbps Serial ATA specification means very little. This third-generation standard's claim to fame is a faster host interface capable of shifting bits at 600MB/s—twice the speed of the old 3Gbps spec. However, that 300MB/s "SATA II" interface was hardly a bottleneck for traditional hard drives. Even Western Digital's latest VelociRaptor, which is the fastest mechanical drive that plugs into a Serial ATA port, can only sustain transfer rates up to 152MB/s. The 'raptor's cache didn't push much more than 236MB/s in our burst speed tests, either, giving the drive little chance of living up to its 6Gbps interface speed.

Gigabyte has been all over the new SATA 6GB/s and USB 3.0 technologies with their latest line of X58A-based motherboards and we finally got the opportunity to test drive one for the LGA 1366 platform. We received the X58A-UD3R for our review today that has been winning hardware review awards left and right from across the tech review empire.

If you are a system builder looking for the absolute lowest power consuming PC then RAM may be something thats overlooked. Extremely low voltage RAM like the kit of HyperX we have here today can really help bring down power usage. This can be a great building block for an extremely low power PC. This also future proofs your components in a way since Intel has stated that the next generation of CPU's will use even lower voltage DDR3 than what is common today. However we will be using this RAM on an AMD  based system which does not require the RAM to run at 1.65 volts or lower. This may be the case in a lot of computers since AMD makes some of the most power efficient CPU's currently available.

With so many CPU coolers saturating the market these days, it's hard to pick from all the options that are out there. Noctua has proven in the past that their strive to produce coolers that combine the performance to keep overclocked multi-core processors cool, while being nearly silent in operation at the same time, is quite attainable. Today we will be taking a closer look at the Noctua NH-U9B SE2, a smaller unit designed to fit into tight spaces while still providing the popular "push-pull" fan setup found on many tower designs.

The Xtreem Dark kit ships in the signature green cardboard box with the X-shaped window up front. There is also a white sticker - similar to that which you will find on the memory modules themselves - with all the information about which Xtreem Dark variant you will actually be finding inside the package. The rear goes into some technical detail about the modules and has a list of awards printed on them as well. Maybe we will see ours on there one day?

Lately it seems like the 1366 socket CPU's have been completely forgotten. Ever since the 1156 socket CPU's launched most manufacturers have been busy optimizing their hardware for 1156 socket compatibility. There has been a couple new features added to X58 chip-set based motherboards, like SATA III, USB III, and USB Power III (on some motherboards), but in the memory category it seems like the manufacturers only care for the P55 chip-set based platforms and not the proven, much more powerful, X58 chip-set based platform. Since February, Intel has released a couple new CPU's for the 1366 socket. The Core i7 930 replaced the Core i7 920 and Intel released the hex core, Core i7 980X CPU. Unfortunately, no enthusiast memory kits followed.

Better known for their video cards and motherboards, MSI's mobile line-up has been gaining a lot of attention these days. Their product line is logically divided into four classes: Classic for general consumer models, Wind for ultra mobile products, G for gamer and high performance notebooks, and X-slim for thin systems. Today we are looking at MSI's latest Wind 200 series wind notebook: the U230-040.
