problemas con procesadores Dual Core

A.- PROBLEMAS CON EL DUAL CORE:

 

Microsoft ya ha admitido hace tiempo que Windows NO funciona bien con los dual-core. Mira esto:

Has de instalar un HOTFIX para idioma SPANISH. Si pones otro no funcionará (y me ha costado un huevo encontrar el correcto por que Microsoft parece que lo esconde).

Si quieres investigar más hay hasta un web dedicado: http://www.thehotfix.net/

 

El problema sigue persistiendo a pesar de los parches, hotfix y las puñetas que van sacando. Esta es la mejor explicación que he encontrado sobre el arreglo:

The performance of your multitasking and games (ex. BF2, Oblivion, etc) would be a lil F'ed Up if the dual cores are not both being utilized because the setting for your Windows isnt set correctly. This hotfix is for those that want the most out of their Dual Cores. If you are just a casual PC user, this hotfix might not do anything for you. But if you multitask and game, you definitely see an increase in performance. As well as if you do Professional Audio editing and Video editing, this will also help you greatly.

 

Therefore (here's how to check -OR- do it yourself):

Required:

- Windows XP with Service Pack 2 (even when using Apple Bootcamp, NOT Virtual PC)

- Any system (desktop or notebook... even Apple's MacBook Pro) with multi-cores, multi-processors, multi-logical processors (Hyper-Threading)

---- Intel: Pentium 4 w/ HT, Pentium D, Core Duo, Core 2 Duo, Dual Core Xeons

---- AMD: Athlon 64 X2, Turion X2, Dual Core Opterons

 

1) The mandatory Windows XP Hotfix Patch: KB896256 (NOT automatically downloaded with Windows Update) and the AMD CPU drivers (Intel Core (2) Duo doesnt need it) should be installed,

if not download KB896256 XP patch (mirror 1 mirror 2), AMD CPU Driver & AMD Dual-Core Optimizer (Read Note 2), (Core (2) Duo's dont require a driver) and install them.

Note 1: Only install the AMD Driver and AMD Dual Core Optimizer if you have an AMD CPU.

Note 2: BSOD's.... If you own a Clevo D900K (A.K.A. Sager 9750, Alienware Aurora m7700, etc) notebook, DO NOT install the AMD Dual Core Optimizer... incompatible. So if you experience BSODs (on any computer) from the AMD Optimizer, then go into Safe Mode and uninstall it. You will still have optimized dual core as long as you do the rest of the guide.

 

(Other Languages) Windows XP Hotfix Patch: KB896256 (from LaptopVideo2go):

 

Code:

German (DEU) - http://www.laptopvideo2go.com/drivers/m ... 86-deu.exe

English (ENU)- http://www.laptopvideo2go.com/drivers/m ... 86-enu.exe

Spanish (ESN)- http://www.laptopvideo2go.com/drivers/m ... 86-esn.exe

French (FRA) - http://www.laptopvideo2go.com/drivers/m ... 86-fra.exe

Italian (ITA)- http://www.laptopvideo2go.com/drivers/m ... 86-ita.exe

Dutch (DUT) - http://www.laptopvideo2go.com/drivers/m ... 86-dut.exe

Turkish (TRK)- http://www.laptopvideo2go.com/drivers/m ... 86-trk.exe

 

 

Note: This is just to save time. It is okay to restart after installing this hotfix.

 

2) go to Start Menu > Run. Type REGEDIT and press enter.

 

The registry location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager should have a key named Throttle there, if not make it by right clicking, point at New > Key... name it Throttle.

 

3) (Still in registry) Inside Throttle key: should be a DWORD called PerfEnablePackageIdle with the value of 1. If not there, right click, point to New > DWORD... name it PerfEnablePackageIdle.

*** Note: You should type 1 in the Value data box to enable the performance state policy behavior (increases performance)

 

 

4) Quit Registry.

 

5) Now look at your boot.ini to make sure that the command /usepmtimer is there, by right clicking on My Computer go to Properties, click on the ADVANCE tab, then under Startup and Recovery click on Settings, then click on EDIT....make sure your boot.ini has the /usepmtimer in there (located in the last line), if NOT then just copy and paste /usepmtimer in there. (NOT the entire boot.ini example)

 

Note: If you have an AMD dual core and installed the AMD drivers, the /usepmtimer would be inserted into your boot.ini for you.

 

BOOT.INI example

 

[boot loader]

timeout=30

default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS

[operating systems]

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect /usepmtimer

 

Go to File and then Save (to save the changes to your BOOT.ini).

 

Restart your computer.

That's it!

 

NOTE: The BOOT.ini that I have given was meant for an example only. I would not recommend you to copy all of it and overwrite your own, unless if you are specifically using XP Pro SP2 on the first partition of the harddrive. Everyone else (XP Home, MCE2005, OEM pre-installed it onto different partition, etc.) should just add the /usepmtimer only.

 

FYI: The /usepmtimer in the BOOT.ini is a "switch" that forces the system to use a steady clock in place of the CPU frequency... for certain timing functions. Thats as basic as you can explain it.

_____________________________________________________________________________

 

To test your newly optimized Dual Core system:

 

I would recommend to compare the before and after scores (from the hotfix) of the following popular benchmarks:

 

PCMark05 -

 

some parts are multi-threaded, measure the performance of your PC and determine its strengths and weaknesses

 

3DMark06 (highly recommended) -

 

multi-thread supported, great to test dual core CPU scores and videocards

 

3DMark05 -

 

single-threaded, less up-to-date than the 2006 version, but still used out there for comparisons. (not that great to reflect optimization difference)

 

SuperPI -

 

single-threaded, tests the CPU performance in calculating a specific number of digits of Pi, commonly used in Overclocking to test stability and speed of the system

 

 

 

 

 

B.- PROBLEMAS CON LA 7950DX2:

 

La tarjeta ha sido mal parida desde el principio, siendo una especie de experimento para probar el concepto QUAD-SLI y crear monstruos. Como verás la tarjeta se ha dejado de hacer y se ha pasado en su lugar a la serie 8000. La tarjeta en si es una bestia capaz de 100 FPS a 1600x1200 con juegos FPS, pero los creadores han pasado de los simuladores y no acaban de sacar un driver que funcione realmente con los programas que nosotros usamos. Así tenemos que con el driver que viene por defecto teníamos 8 FPS en 1280x960 con LOMAC y 14 FPS con iL-2(series)... para llorar. Incluso con los últimos drivers, los beta, los que saldrán, etc... todavía hay muchos problemas y mal funcionamiento. Por ejemplo no hay manera de que salga el HEAT BLURR de los aviones de LOMAC y los FPS en iL-2(series) no pasan de 20 FPS mirando al cielo y con un STUTTERING que marea, además de dibujar una fea circunferencia negra en el agua.

 

Mirate estos hilos (hay más en la red):

Los últimos driver están aquí (por alguna razón no están en la página oficial de nVidia): http://downloads.guru3d.com/

No uses nada anterior a los 96.89

 

Para ajustar las configuraciones de la tarjeta y del conf.ini de iL-2(series) no hagas caso a ningún "experto al instante" que aparecen habitualmente en los foros y aprendelo tu mismo aquí:

Muy buen post Revi... muy muy interesante :plas:

[topino]

Yo lo baje y lo he instalado, pero no me atrevo a cambiar el registro y lo otro.

 

No me sale Throttle, etc.

 

¿ Habre conseguido algo sin cambiar el registro ?

[Revientor]

Pues no tengo ni idea...

Lo investigare en Mocosoft.
