Boost, set-up and optimization of the videosubsystem

The writer does not bear liability for possible(probable) mortality of a videocard or diverse components The computer, which one can take place as a result of attempt of boost

If the subject of boost of the processor is lighted and is investigated(studied) well enough, problems tangent Boost of a videocard or data links to her, remain in a shadow. However, it does not mean, That a videocard - device which is not yielding to boost. There is a weight of capabilities for acceleration Activities of a video memory and other a component of the videosubsystem at the help specially of designed utilities. In this material we shall try to light all similar programs and their applying. A principle of operation The majority of the programs for boost of the videosubsystem is encompass byed a frequency drift, on which one The memory of a videocard works. By default she is established(set) of videobiosomes, but can be program Is changed, for example at a loading.If the subject of boost of the processor is lighted and is investigated(studied) well enough, problems tangent

All depicted below utilities I work under DOS. Only programs PowerStrip, Rendition PLL Calculator and Riva128 Registry Tweak work under Windows.

Boost of the videosubsystem in the computer on the basis of processors Pentium Pro and Pentium II

The speed of activity of a video in such system (both with PCI, and with AGP) can be increased in two or more times, By applying the program FastVid. And, the similar effect is reached Only at the expense of the sanction of modes write posting � write combining -- Capabilities Pentium Pro/Pentium II Chips which were switched off by default.
At applying FastVid transfer rate through trunk PCI increases with 8 Mb / with up to 90 Mb / with ( Or even up to 150 Mb / with at usage of the trunk AGP).

The program FastVid resolves usage of three functions:

• At first, the sanction write posting allows to begin to the processor transfer(transmission) of a following portion The videodata without waiting the termination(ending) of the previous transfer(transmission). Thus, the transfer rate increases In 10 times.
  However, in all new motherboards this mode already is included by default.
• Secondly, usage Banked VGA Write Combining (VGAWC) allows To cache of the reference(reversal) to a video memory, optimizing them, outgoing from her(it) of organization.
  Till all of visibility, this algorithm is not realised hardware in chips of the motherboard, for best Compatibility.
  Such kind(view) of optimization picks up speed data transfers in 5 times.
  Some new motherboards, for example productions of the corporation Asus , have a capability Actuations VGAWC by means of BIOS Setup.
• the Third function, Linear Frame Buffer Write Combining , allows to organize Than the reference(reversal) to a video memory around of the gear, on specific addresss is higher 2Gb.
  At implementation of this capability, the speed of the appeals, naturally, increases, as necessity To toggle banks passes, and the processor receives a capability to work with a video memory directly. But for usage Linear Frame Buffer Write Combining it is necessary to involve the MSR-registers The processor, therefore by default this mode is switched off for assuring compatibility.
  Theoretically, the speed at applying this function increases in 5 times.

To download FastVid it is possible from here: < A HREF = "fastv110.zip.htm" tppabs="http://ixbt.stack.net/video/utils/fastv110.zip">fastv110.zip (28Kb) < P>  < P>  < A NAME = "q2" > < H3 CLASS=plane > Boost of videocards on chips of corporations S3, Cirrus Logic, Tseng and Trident

For boost of videocards on chips of corporations of corporations S3, Cirrus Logic, Tseng and Trident can be applied The program MCLK . This program allows to change the frequency, on which one The memory works a video. By default, she is set of videobiosomes, and not always corresponds(meets) maximum To capabilities of memory. The applying MCLK for increase of frequency allows to pick up speed activities Videosubsystems on 20-30 of %.

MCLK supports following videochips:

• Cirrus Logic 542X, 543X, 544X and 7543
• S3 86x, Trio (Trio32, Trio64, Trio64V +), Virge, Virge/VX and Virge/DX
• Trident 9440/96xx
• Tseng Labs ET-6000

Have in view of, that strong boost of a video memory can result, both to malfunctions in its(her) activity, and to To mortality of all chip.

The utility NV3TWEAK can be applied for acceleration of 3D-functions on videocards with these chips, Optimizing activity 3D- and remedying some error. The writer of the utility Daniel Di Bacco ( Daniel Di Bekko, < A CLASS=email HREF="mailto:[email protected]">[email protected]). The utility optimizes of set-up of adapters for activity under Direct3D and OpenGL and eliminates Problem of noncompatibility with some games. The adjustability of colors saturation (gamma) and is provided Preservations of these adjustments.

The current version of the utility NV3TWEAK is counted for activity with drivers of videoadapters, Built on the basis of drivers from the company nVidia of the version 2.0 or is higher. Among maintained Plates there are products from Diamond and Elsa.

< A NAME = "q5" > < H3 CLASS=plane > Boost of videocards on the chip Rendition Verite V2X00

For an alteration of speed of activity of a video memory on a card with this chip, it is necessary to edit The file < STRONG CLASS=blue > VERITE.INI , stored in the Windows - directory.

Strings(line)
[display]
m=33
n=2
sclkp=4

This file determine frequency, on which one the video memory and chip works.
Frequency of a video memory = 14.318 x m / (n x mclkp) , and frequency of the chip = 14.318 x m / (n x sclkp) .

The company < A CLASS=teal HREF="tppmsgs/msgs28.htm#2856 " tppabs = " http: // entechtaiwan.com / " > EnTech Taiwan has submitted us a capability to offer To the holders(owners) of videoadapters on chips Rendition Verite 2100/2200 New charge-free the utility for boost of these geometry processors:

In last version from February 26 there is a capability to apply changes at once, without reboot Operating systems also has appeared firm Rendition.

the Program PowerStrip

The creator of this program is the company EnTech Taiwan ,  http://entechtaiwan.com/. The program works under operating systems Windows ' 95/98, Windows NT. The most pleasant(sweet) feature - availability The russian interface. This program is look-alike MCLK, but except for an alteration of speed of activity of a video memory, PowerStrip allows to change scan frequencies of the screen monitor and to set up(adjust) videomodes.

Attention, program PowerStrip Is counted on activity with drivers and bioses generated(set up) implementators Graphic chips, and consequently can is illconditioned to work with drivers written producers Some videoadapters.

The utility Power Strip has following capabilities:

• Frequency of vertical development(display,scan) (updating(up-dating) of a screen) up to 200Hz
• Switching(changeover) on the move of depth of submission(representation) of colour
• Control of calibration of colour completely independent from the driver
• Set-up of the sizes and rule(situation,position) of a screen
• the Control of clock rate, on which one works a video memory
• Assigned by the user of shortcuts
• Auto definition and support of chips 3Dfx and PowerVR
• Support of miscellaneous languages
• the Built-in processor of savers of screens
• Support DirectX and OpenGL
• a Full integration in the interface Windows
• Full support Windows NT 5.0
• Full diagnostic AGP and PCI of devices
• ��-independent implementation DDC

Value of frequencies for video memory for this program are set in file pstrip.cfg in Section
[a title of the chip] < /CODE > < BR > �
MClk=90,110,100

Parameter < STRONG CLASS=blue > MClk just also determines frequencies of activity of a video memory. 90 - minimum frequency, 110 - maximum. In these limits its(her) change from the program is authorized In a conversational mode. However, you can increase maximum rating and achieve even greater Productivity(output). 100 is a default value.

PowerStrip supports chips: < UL CLASS=red >

Now given utility Is counted and on the end user! The company EnTech kindly has submitted us a capability to offer you for a loading last The version of the utility. Now PowerStrip completely supports operating system Windows 95/98 and NT 4/5.

Let's remark, that in case of usage more than two Videoadapters under Windows98 or Windows NT 5.0, the utility works only with a primary videocard. Outside of The availability DirectX of the version not below 2 is necessary for relation to the version Windows
