DDR3-2400MHz On AMD's A10 Kaveri With Kingston's HyperX Beast

Earlier in the week I published benchmarks showing AMD Kaveri's DDR3-800MHz through DDR3-2133MHz system memory performance. Those results showed this latest-generation AMD APU craving -- and being able to take advantage of -- high memory frequencies. Many were curious how DDR3-2400MHz would fair with Kaveri so here's some benchmarks as we test out Kingston's HyperX Beast 8GB DDR3-2400MHz memory kit.

G.SKILL 8GB DDR3 Laptop Memory On A Linux Ultrabook

With my purchase last month of the ASUS Zenbook Prime as a new Intel ultrabook for carrying out some development work while traveling, the only two traits of the system that I didn't like were the use of an Ivy Bridge processor over Haswell and that it had only 4GB of DDR3 system memory. Fortunately, the latter can be easily corrected and with the ultrabook order I bought a 8GB G.SKILL DDR3-1600MHz DIMM for this Core i7 system that I dual-loaded with Fedora 20 and Ubuntu Linux.

OCZ DDR3 PC3-12800 Black Edition

As can be seen in many Phoronix articles and in the memory reviews themselves, OCZ memory is quite common to Phoronix. While OCZ Technology is only eight years old, they have done a phenomenal job at building a terrific brand that is highly regarded among enthusiasts, gamers, and professionals. OCZ has expanded over the years from just being a system memory producer to a vendor of interesting flash drives and high-performance SSDs, among other products, but in this review we have caught ourselves looking at another OCZ DDR3 memory kit. The OCZ DDR3 PC3-12800 Black Edition kit is specifically designed for use with AMD's latest processors and chipsets.

CSX 3GB DDR3-1600MHz Memory

Unless you are located in Germany or some other parts of Europe, chances are you have never heard of Compustocx. Compustocx, or CSX for short, is a German manufacturer of system memory modules for computers and is one of the largest memory upgrade providers for Apple computers. CSX has also ventured into producing solid-state drives, audio products, and FB-DIMM memory. Recently though we were asked by a US representative for Compustocx to look at one of their newest DDR3 memory kits, which we gladly accepted. The RAM we are testing out today is the CSX 3GB DDR3-1660MHz (CSXO-CEC3-1600-3GB-3KIT) memory kit.

Intel Atom 2GB Memory Performance

Most netbooks currently on the market offer 512MB or 1GB of system memory and only a single DDR2 SO-DIMM slot. However, with most of the netbooks a 2GB memory module could be easily installed, but what performance benefits does that yield for an Intel Atom powered device? In this article we have a few benchmarks comparing the 1GB versus 2GB memory performance on the Atom-powered Samsung NC10.

A-DATA Vitesta Gaming DDR2-800 4GB Kit

Last week we had looked at the Corsair DHX 4GB DDR2-800MHz memory, which performed and overclocked very well and featured Corsair's exclusive Dual-Path Heat Xchange cooling technology. Today though we are looking at the more mainstream A-DATA Gaming DDR2-800 4GB Kit. This memory is less expensive than Corsair's DHX memory, but has higher latencies and simple heatspreaders. As you will find from reading this article, the overclocking potential is quite limited.

Corsair DHX 4GB DDR2-800MHz

It's been a while since last looking at any Corsair memory at Phoronix, but up for review this afternoon is their latest TWIN2X4096-6400C4DHX memory. This DDR2 memory features Corsair's DHX technology for cooling the memory ICs with EPP latencies of 4-4-4-12 and run at 800MHz. Like many other Corsair products, the TWIN2X4096-6400C4DHX is also backed by a lifetime warranty.

OCZ ReaperX HPC 4GB PC2-6400

Last July we had looked at the Reaper HPC DDR2 memory from OCZ Technology, which not only was clocked well for its time with a memory frequency of DDR2-1066MHz, supported NVIDIA's EPP (Enhanced Performance Profiles), and boasted OCZ's admirable lifetime warranty with EVP (Extended Voltage Protection), but it was the first model to bring forth their next-generation patent-pending memory heatspreaders. The Reaper HPC (Heat Pipe Conduit) cooling solution is made up of normal heatspreaders attached to the ICs, but bonded to the top of that is a single copper heatpipe in a loop that passes through an aluminum fin array. We were pleased by both the cooling and memory performance with the Reaper HPC, but OCZ Technology didn't stop there in their quest to deliver 110% customer satisfaction. OCZ has taken their Reaper HPC design to the next level by strapping on two copper heatpipes, ensuring that each memory IC is in direct contact with one of these thermo-conductive pipes, and greatly increasing the size of the aluminum fin array. This newest memory cooling solution is known as ReaperX HPC and can be found on the PC2-6400 ReaperX HPC EB 4GB dual channel kit, which we are reviewing today.

A-DATA Vitesta DDR2-800 Extreme

A-DATA has only been around since 2001, but in the past six years A-DATA has come to market with a number of DRAM memory products. Their current selection of products now range from Disney flash memory drives to desktop and notebook DDR2. For review today we have a 2GB kit of A-DATA's Vitesta DDR2-800 Extreme Edition memory. These memory modules are designed to operate at DDR2-800MHz with 4-4-4 timings or DDR2-1066MHz with 5-5-5 timings, and are backed by NVIDIA EPP support.
