During the scan, you will see options to change the type of scan and how many times to scan. Once the scan finishes, Windows will start, and within moments a bubble notification will appear, stating that the scan is finished. Memtest86+ does have more options, but requires a separate download and has to be burned to a disc, and does not generate a printable report.
Memtest86+ will boot from a USB Flash drive (as I used last week just before returning it). Click On start in search box Type "memory test" you will see memory diagonistic tool highlight it and press return.

SiSoftware Sandra Installation - Let's you select on Windows XP Professional x64 Edition if you want to install the 32-Bit version or the 64-Bit.
An important new feature in the x64 processor architecture is the Data Execution Protection (DEP) bit that controls which areas of memory can be used to execute code. Beginning with Windows XP Service Pack 2 (SP2) and continuing with Windows Server 2003 SP1 and Windows XP Professional x64 Edition, Windows uses DEP to prevent malicious code from being able to execute, even when a buffer overrun occurs. With the introduction of x64 processors, both AMD and Intel added hardware support for DEP. While DEP is by no means a substitute for a well-designed and implemented anti-virus and anti-malware deployment in any organization, it is an important additional layer of protection that would have prevented the spread of the MSBlaster worm had it been widely implemented at the time.
You can take a look at some more photos with the changes from the 32-Bit to 64-Bit version that we found on the game homepage here. Farcry is an awesome First Person Shooter (FPS) based on a last generation 3D engine named as CryEngine. A great advantage and strong point of the CryEngine is its physics system which supports character inverse kinematics, vehicles, rigid bodies, liquid, rag doll, cloth and body effects. For all you racing fans out there, this test is for you and will represent the Racing game category in our benchmarks. To measure performance on the game we used fraps to get the average fps of the whole 8th stage of UK which is actually the only stage you get to play on the demo. Regarding the storyline, the player again picks up the crowbar of research scientist Gordon Freeman, who finds himself on an alien-infested Earth being picked to the bone, its resources depleted, its populace dwindling. Characters - Advanced facial animation system delivers the most sophisticated in-game characters ever seen.
Physics - From pebbles to water to 2-ton trucks respond as expected, as they obey the laws of mass, friction, gravity, and buoyancy. To measure performance we used the Video Stress Test(VST) that is available in the CounterStrike:Source beta available through Steam. 3D Mark is a widely used and accepted benchmark that stresses the DirectX performance of a VGA card. This test also uses post-processing effects, such as Depth of Field and Bloom effects which are widely used in today's game cut scene sequences. Mother nature represents the level of effects and realism that are possible using 2.0 vertex and pixel shaders, plus some other features that DirectX 9 offers. Just like its predecessors, 3DMark05's point system is set so that at the moment of release, the high-end VGA cards available in stores can only score around 5000 3DMarks, whereas the worst card that meets the programs requirements yields a score of 1000.
This test, tries to simulate a future first-person shooter game with all the high details that entails.
A large number of trees with their branches swinging separately, and dense vegetation being dynamically distributed according to the camera movements, make this test the most demanding of the three.
PCMark04 is an application-based benchmark and a premium tool for measuring overall PC performance.
SiSoftware Sandra (the System ANalyzer, Diagnostic and Reporting Assistant) is an information & diagnostic utility.


This test involves the generation of Mandelbrot Set fractals that are used to realistically describe and generate natural objects such as mountains or clouds. This tests examines how your memory sub-system compares to other systems with the same or similar memory. This Benchmark is a composite figure representing an overall performance rating based on the average of the read, write, and seek tests, and file and cache size.
The Persistence of Vision Ray-Tracer (Pov-Ray) creates three-dimensional, photo-realistic images using a rendering technique called ray-tracing. Ray-tracing is a rendering technique that calculates an image of a scene by simulating the way rays of light travel in the real world. Ray-tracing programs like POV-Ray start with their simulated camera and trace rays backwards out into the scene. For every pixel in the final image one or more viewing rays are shot from the camera, into the scene to see if it intersects with any of the objects in the scene. Special features like inter-diffuse reflection (radiosity), atmospheric effects and area lights make it necessary to shoot a lot of additional rays into the scene for every pixel. Anyone who has used computers for any period of time will understand the importance of having a stable system. As we can see from the table below, Windows x64 kernel takes 60% more memory than Windows XP 32-Bit Edition.
While AMD and Intel have different names and slightly different implementations for this feature, the result is an enhanced layer of hardware protection against some of the most destructive worms and exploits of the past several years.
Even without a processor that supports DEP in hardware, Windows is able to detect code running from memory locations that it should not. The processor sets the No Execute bit (for AMD processors) or the Execute Disable bit (for Intel processors) on all entries in the memory address table that are for data only and should not be executed. With a past best left behind you, you'll be focusing on your present assignment: escorting an ambitious journalist named Valerie Cortez to the Island of Cabatu.
Real-time editing, bump-mapping, static lights, network system, integrated physics system, shaders, shadows and a dynamic music system are just some of the state of-the-art features that the CryEngine offers. All physics seem to be very realistic and you never get bored when facing enemies, since character models have multiple animations that blend in believable ways. Gamers keeping the excellence of Half Life 1 in their mind as well as the remarkable E3 demo preview, have been anxiously waiting for the much delayed release of HL2. Freeman is thrust into the unenviable role of rescuing the world from the wrong he unleashed back at Black Mesa.
They can assess threats, navigate tricky terrain, and fashion weapons from whatever is at hand.
We set all the details to the highest level and each time changed the resolution from 800x600 up to 1600x1200. A very strong point of 3DMark is that it's VGA card measuring is does not require any CPU power. The dynamic shadows, high-detailed environment and advanced lighting techniques ensure that under normal circumstances, no recent card can run it with decent frame rates. The airmen defend their ship using heavy cannons, but these seem to have no effect on the huge sea monster. It uses portions of real applications instead of including very large applications or using specifically created code.
It should provide most of the information (including undocumented) you need to know about your hardware, software and other devices whether hardware or software. In an attempt to model real world demands and performance, SM2 is a suite of high-performance benchmarks that realistically stress system performance without architectural bias. It has the flexibility of simulating any 5 noble gases, in 3 different crystallographic configurations, with variable numbers of atoms at a user specified temperature. Primordia outputs the total all electron energy of the atom in addition to the kinetic and potential contributions.


Primordia and QMC are indicative of what is done in commercial chemistry codes on workstations and supercomputers about the world. Similar tasks are performed by automotive, aerodynamic and civil engineering companies during their product design. Sean's AES 128 bit encryption algorithm is quite possibly the fastest implementation on the face of the earth. It reads in a text file containing information describing the objects and lighting in a scene and generates an image of that scene from the view point of a camera also described in the text file. The user specifies the location of the camera, light sources, and objects as well as the surface texture properties of objects, their interiors (if transparent) and any atmospheric media such as fog, haze, or fire. These "viewing rays" originate from the viewer, represented by the camera, and pass through the viewing window (representing the final image). For this purpose rays are sent backwards to each light source to determine the amount of light coming from the source.
As a result, in order to gain the same performance level with the 32-Bit, users must upgrade their system memory.
If code attempts to execute from within an area of memory marked as data only, Windows will raise a status access violation exception and terminate the process. However 3DMark03 used DirectX 9 specific features in a limited manner, because fully supporting hardware was rare at the time of its launch.
The magic fireflies have flickering bright green lights that playfully move around the forest.
The water not only does realistic looking reflections and refractions, it has a depth fog, making the sea monster swimming under the airship actually look deep down in the water. This allows PCMark04 to be a smaller installation as well as to report very accurate results.
Synthetic benchmarks are useful, and can tell the user valuable performance characteristics about their system's performance, but they should not be used in entirety to measure system performance; this role is reserved in greater part to real applications performing real tasks. Ray-tracing is not a fast process by any means, but it produces very high quality images with realistic reflections, shading, perspective and other effects. If you are lucky your data will only become inaccessible while faulty components are replaced.
In contrast, 3DMark05 requires DirectX 9 hardware with full support for at least Shader Model 2, and takes shader usage to never before seen levels. As far as possible, PCMark04 uses public domain applications whose source code can be freely examined by any user.
The weighting of the results is not equal that it represents the distribution of different files sizes as used on these devices (obtained through field research).
Science Mark 2.0 is comprised of 7 benchmarks, each of which measures a different aspect of real world system performance.
If the surface is reflective or transparent new rays are set up and traced in order to determine the contribution of the reflected and refracted light to the final surface color. Science Mark 2’s optimized implementations of matrix multiplication in single and double precision, from an algorithm point of view, perform remarkably better than the blind man's matrix multiplication routine.
Even if you have good backups, you can still lose days of work returning the PC to its pre-failure state. BlasBench uses building blocks called kernels at its lowest level that determine overall MFLOPS performance. Because the vast majority of rays never hit an observer, it would take forever to trace a scene. These kernels are written in C and a wide assortment of assembly forms (SSE Vector, SSE2 Vector, SSE2 Scalar, x87, 3DNow!
