How to install the AMD X2 Hotfix Patch

How to install the AMD X2 Hotfix Patch

Are you having issue's with gaming performance?

I realised there must have been something wrong when I installed a second 7900GTX to put in SLI and found that I was getting 60-80 FPS in Counter Strike Source. There was jerkyness and stuttering in-game.

This is a quick guide on how to get rid of these issues. It is not 100% guaranteed to work: but many people have found that it helped.

Please make sure you do a registry backup first.

This guide is not for those who are scared of messing with Windows. Back up your PC beforehand.

1. First things first

The first thing to do is to download and install the AMD Drivers from here. They are called "AMD Athlon™ 64 X2 Dual Core Processor Driver for Windows XP and Windows Server 2003 Version (x86 and x64 exe) 1.3.2"

While you are on that page download the "AMD Dual-Core Optimizer" as you will need this later in the article.

2. Download the Hotfix

Download the AMD Hotfix from here. further information is here

Install the Hotfix.

3. Edit your registry

This is to enable the Hotfix

Go to Start>Run>Type regedit in the dialogue box then click "ok"

In the regitry navigate to: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession Manager

You get here
regiedit

Then go down to "Session Manager" and right-click. from the menu choose "New"

AMD hotfix

The Key is to be named "Throttle". Once this is created right click "Throttle" and select New>DWORD Value

In the value name type: PerfEnablePackageIdle

Then click "modify". in the Edit DWORD Value box, type 1 and check the this is Hexidecimal.

4. Check your boot command menu

This should have this feature in it: /usepmtimer

to check this go to Start>Control Panel>System

The go to the "Advanced Tab" and click "Settings" on "Startup and Recovery" and then "EDIT"

AMD dual core driver fix

If this is not in there add it to the list.

5. Install the dual Core Optimiser

Remember that Optimiser that you downloaded earlier yes? Install it now.

You BOOT.ini should now look like the one above and you should be set to go!

There may be a few reboots in the gaps of the instructions - but go with the flow and reboot as asked.

Uninstallation

Here's how to get rid of it.

* - Uninstall the Hotfix, go into ad/remove programs, click on show updates and remove update numbered KB896256

* - Reverse the registry entry (from your earlier registry backup)

* - Uninstall the AMD drivers.

* - Uninstall the AMD Dual Core Optimizer.

* - Done.

Thanks for the info!

I've already applied this hotfix patch few months ago according to this guide and it didn't seem to improved anything. Some people are saying that you don't need to apply it, unless you're using the "Cool 'n Quiet" option, but this guy says it isn't true and it is adviced to install it anyway...

Here is how to get your dual core AMD system running like it should with no hitches and stibility issues..............since the new AMD DUAL CORE OPTIMIZER came out people say you dont need the MS HOTFIX anymore, i dont know if this is true or not, but i tested these fixes with and without one another, and found they work better together, giving an increase in performance.....but thats from my personal expierience......try for yourself, i recomend installing both the MS HOTFIX and the AMD DUAL CORE OPTIMIZER, as they work good together and also give a performance increase by about 1-5%.



Oh...one more thing, you should also install the new AMD X2 Drivers (AMD Dual-Core Optimizer) BEFORE applying this HOTFIX...

Hope this helps...Quote

If you read the guide it goes through the whole thing and gets you to install the patch and then the Optimiser Quote

I'm REALLY REALLY sorry!!! I got confused, you're absolutely right!!!

One should first install the HOTFIX and just afterwards, install the OPTIMIZER!!!

Anyway, this way or the other, it didn't have ANY EFFECT on my overall performance, or at least, nothing noticable...

Thanks for enlightening me for my mistake...Quote

Is it a known problem, because I've never heard about Intel Dual-Cored CPUs problem, or is it just a problem in your specific rig?

What "slow-down" do you get, in FPS? and on which games? Maybe you should "google" for some "Video/Graphics" optimizations for a specific game where you encounter these slow-downs...Quote

Its just in Counter Strike to be honest. More than 5 ppl on the screen makes the fps drop down to 30, and it just laggs like mad.

I've searched for answers but not turned up much.

Other games that are more graphics intensive work fine :/Quote

That's strange, as you've got a pretty strong CPU and a strong Video Card.

I have X2 3800+ and 7800GTX Video Card and I didn't have any lags during gameplay when I've played this game...

Anyway, like I've already said, you should try to "google" for a "special" graphics optimization (may involve some registery/drivers tweaks) for that game...

If I'll find anything useful I'll let ya know...Quote

Cool thanks. I'm changing motherboard/processor soon so hopefully that will get rid of it. The strange thing is, that even reducing detail and AA/AF settings does not reduce the lag - its almost like its programmed in - olQuote

Yeah, that's bul***t, I don't know who told you that and/or where did you hear it from, but don't worry...Windows XP Home FULLY supports the Dual-Core, as well as ALL other Win XP versions...

I guess it'll be the same for the Vista...Quote

Well, the thing is unless u`ve installed in a certain fashion, it will almost act like u`r using a single processor. And u need to install things in the correct way/order. I did my first install backasswards and it kept restarting on me like I had a hardware problem, randomly.Quote

All windows XP supports multiple coresQuote

Yep all Windows versions from 2000 up support 2 physical processors. For anything more than 2 physical processors you need to purchase a server copy of Windows.

How this affects quad-core I dont know, but i'd assume Windows can tell the difference between 4 cores and 4 physical processors.Quote

Yeah...Windows XP (at least I know for the Pro version) FULLY supports even Quad-Core, as at my workplace we're using TWO Opteron 270 Dual-Core CPUs on the same mobo (TWO 940pin CPUs, each one 2GHz Dual-Core CPU) and Windows XP support them...Quote

I actually work in an AOI company, which manufacturers machines for AOI (Automatic Optical Inspection) of PCB (Printed Circuit Boards)!!!
