Offering up to an astonishing 2.4x of extra processing power for Your computer's integrated graphics engine, the GMABooster is a must-have tool for every user interested in advanced 3D gaming, truly flawless Windows® Vista and Mac® OS X experience, smoother operation of Google® Earth, improved video playback, and perfomance gain in a variety of professional applications!
Frequently Asked Questions List Q.: 2.4x boost without adjusting the voltage (right, Your hardware will not be exposed in any way!), how is it possible? A.: A short preamble is needed to explain what makes a GMABooster technology possible. Let's consider an Intel® Graphics Media Accelerator 950 (GMA 950). This integrated solution, while not fully supporting the latest and the most demanding games, still allows a user to enjoy the mass of brilliant gaming hits of all genres. GMA 950 does also fully support Aero and QuartzGL (enhanced GPU-driven user interfaces of Windows® Vista and Mac® OS X). It features a basic video playback acceleration, as well. However, if You have own a laptop/netbook/nettop computer built on Intel® 945GM/GME/GMS or GSE943/940GML/GU Express chipset, the above statements may not be truth for You. These all chipsets are LV (low voltage) versions of what we normally call Intel® 945. Thus, integrated graphics core has been underclocked dramatically: 166/133 MHz instead of 400 MHz (default GMA clock in a "normal" Intel® 945 chipset). But the truth is, the indicated devices could handle up to 400 MHz with ease: at a nominal low voltage, without the loss of system stability, and with minimal to none impact on thermal specifications/battery life (proven by preliminary testing). Here the GMABooster comes! It allows a user, not a manufacturer to choose the desired GMA speed. It combines a sophisticated assembler-level technology and the user-friendly graphic user interface, offering You to near double the GMA core perfomance without even a need to restart a computer. GMABooster may be considered as a safe, free, "software-level" GPU core upgrade! Q.: The boost in game "X" is about 25%, while in pure GPU tests (like 3DMark® '05/'06 Pixel Shader or Texturing tests) I see a whopping perfomance increase, just as expected (I mean, as might be predicted with calculator) - up to 2.4x! Why is it so? A.: In some real games or benchmarks the so alluring boost may be *quite limited* either by CPU (most of supported devices come with Intel® Atom which is typically 1/2 of already low-end Celeron M which runs at a same clock) or a by shared RAM speed (this is just a single-channel DDR2 533 shared with CPU). Furthermore, even if the CPU load is not 100% during the specific 3D test, this is not because the Atom is powerful enough, but because RAM bandwidth is so much utilized by GMA that CPU is not receiving enough data to process. In any case, GMABooster does its work, and there are simply no other methods to get at least that kind of boost (e.g. 25% in WoW, as reported by users). Q.: On my laptop a popular diagnostic utility GPU-Z reports that I already have GMA 950 running at a speed of 400 MHz. Do I still need the GMABooster? A.: Well, GPU-Z detects GMA 950, but does not read its actual clock. This is a known issue. Please note that there are no devices built on Intel® 945GM/GME/GMS/GSE or 943/940GML/GU Express chipset which have GMA 950 running at a default clock of 400 MHz. So, an answer is: yes, the GMABooster is still needed. Q.: On my laptop a popular diagnostic utility Lavalys® Everest reports wrong ("1 step down") GMA core clock. Is it a defect? A.: Lavalys® Everest is not correct in its readings. It cannot handle the GMABooster-hacked HW clock control registers properly, that's an answer. So, Everest reports 250 MHz for actual 400 MHz, 200 MHz for actual 250 MHz, and 166 MHz for actual 200/166 MHz (for both).
