Making Windows XP use your DUAL CORE BETTER!!!!

Instructions for enabling multiprocessor power performance support on Windows XP:

1. Windows XP must have Service Pack 2 applied.

2. Edit boot.ini file in the root directory to add the /usepmtimer option.

For example:

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

Instructions for enabling multiprocessor power performance support on Windows Server 2003:

1. Windows Server 2003 must have Service Pack 1 applied.

2. Edit boot.ini file in the root directory to add the /usepmtimer option.

For example:

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows Server 2003" /fastdetect /usepmtimer

SAVE THE CHANGES AND REBOOT

You can do this with all Windows XP versions, must have service pack 2!

Go to boot.ini in your root directory and add parameter /usepmtimer

Save the file and close and then reboot!

I got really boost in some games! I also have Lock-on and it really boosted my flightsim! And it works in more games than only that!

My specs are Intel Pentium Dual Core 3Ghz 830 cpu

Intel mobo with 1024Mb ram

Geforce 6700XL 128Mb

SBlive! 1024

Windows XP Home edition.

For systems with AMD x2 CPUs and some games, this switch may actually cause stuttering:

It CAN cause stuttering, but I have an Intel Dual core Pentium 4 830 cpu and with me it also works!!

I especially notice it with the flightsim Lock-on! Runs smoother and more FRPS!

So not only AMD owners should try this, I did also and works for me.

does it work with windows media center? i have amd 3800+x2 dual core. i have the service pack 2, but i do not have the option in my boot.ini directory.

[wenker 0]

I am not seeing where you see these options with the usepmtimer.. i do not see these options ina the boot.ini msconfig screen, nor the windows property screen.

[Mister Frag 0]

Windows XP Media Center Edition is still based on the XP operating system, so it should work on your system as well.

The BOOT.INI file is a system file, and if Windows Explorer is configured not to show protected system files or hidden files, then you won't see it. You can change this behavior using Tools -> Folder Options -> View in Windows Explorer, or you can give the full path name to the file to Notepad, and it should open the file anyway.

[wenker 0]

can you be more specific?

[Mister Frag 0]

Enable the "Show hidden files and folders" option, and disable "Hide protected operating system files".

While you are at it, enable the launching of windows in separate processes, and turn off the hiding of extensions for known file types -- that's lame.

ok i changed all of those options.. now do i have to edit the file in notepad? cause i can not find an option for the usepmtimer any where at all? any guidance you can give me.. i really would lke to unlock this other processor.

[Mister Frag 0]

Claymore explained it quite well -- open up the boot.ini file using Notepad, and add the /usepmtimer option to the end of the line that describes the operating system you boot into:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">[operating systems]

multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect /usepmtimer

Please note that the contents of your boot.ini file may look different -- the important part is that you simply add the /usepmtimer switch at the end of the line without making any other changes.

ok just making sure.. thanks alot.. now do i need to reboot for it to work? and when i put the usepmtimer is there a space beofre the / ?

[Mister Frag 0]

Yes, you will need to reboot. Yes, there must be a space between each parameter.

sweet. i got it to work, and it totally boosted my ofp...instead of ofp reading my processor as a amd 2.00009 x2 dual core. it reads as a 3.9009 am dual core, and it is so much faster. thanks alot

[metallicAL 0]

there may be incombatiblity problems. I played Counter strike source (yeah ok its CS hahaha...) when i fired, it played the sound twice.

Also when i went to ofp prefences it only displayed 3ghz+ once. (shouldn't it say 4ghz? if its a 3800+ 2ghz?)

im not sure if thats because i set the affinaty to 1 core (2 cores cause lag and desync)

btw theres an AMD patch that does this for you.

[Auss 208]

Could you explain exactly wot that command does and how it increases performance. I'll certainly give it a shot

[Auss 208]

I noticed in reference to the AMD cool and quiet drivers that after installing them and rebooting, Both my cores were throttled back to 990Mhz down from 2400Mhz Ouch.. removed the AMD "cool and slow" drivers and it reverted back to normal speed

[Mister Frag 0]

That's exactly what the driver is supposed to do -- it throttles back the CPUs when they are idle to lower power consumption and heat output.

This does not mean that your processor will permanently run at a lower clockspeed. As soon as a process requires enough CPU cycles, the original clock speed and processor state will be restored.

[Auss 208]

Thanx for the reply. Makes sense cheers

Hey guys, I know this might sound like a stupid question, but would this work with a HT processor. I'm not really sure if I have a duel-core processor but in DXDIAG and Windows Task Manager, it shows that I have two processors. Could this be the Hyper-Threading? And if I put that in my boot.ini and I in fact dont have a duel-core processor will it screw up my computer so I cant reboot lol.

Thx in advance.

[Mister Frag 0]

Yes, your P4 processor is HT-enabled if it shows up as two logical processors in Task Manager.

However, the BOOT.INI switch discussed in this thread is not applicable to the P4 processor and won't improve performance. Adding it will not keep the system from booting.

wow i dont know wtf i did but it worked! thanxxx heaps for the help i have been bangin my head on the wall for weeks over this problem! good comp- bad fps now its much better

Mate, you are a freakin McGenius - my already formidable benchmark went from 6400 to 7000. You married?

Hi Wenker

Can you please tell me what processor you are using?

I'm trying to get the same effect by using an AMD Dual Core 4200+ but flashpointpreference sees only an 2200+ CPU.

Thanks in advance for your help.

I guess the 2200 stand for mhz, IIRC a 3800+ has 2000mhz

I also have the same CPU and get OFP preferences showing up as 3200mhz but then if I restart that exe 3 or 4 times it shows up as a 2200Mhz then leave it for a while it goes back to 3200...lol
