AMD Dual Core Fix - Read if you have an AMD Dual Core CPU

mnosteele52 · Post by **mnosteele52** » Mon Mar 13, 2006 10:08 pm

I was having an issue with Firefox scrolling real jerky after my pc was on for a while and I was trying to pinpoint the issue and I came across this fix on a forum named Xtreme Systems, a guy named GAR posted it so props goes to him.

I just did this fix so I can't say whether or not it has fixed my issue but it sounds like a must do fix for AMD Dual Cores. This fixes performance issues with AMD Dual Core CPUs and Windows XP, random slow downs and decreased performance.

I hope this helps someone else.

1 - Install the AMD drivers, download them from HERE.

2 - Read Microsoft's Hotifx information HERE and download the hotfix HERE <--direct download.

3 - Edit your registry to enable the HOTFIX, follow these steps.

1. Click Start, click Run, type regedit in the Open box, and then click OK.
2. Right-click HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager, point to New, and then click Key.
3. Type Throttle for the new key name.
4. Right-click Throttle, point to New, and then click DWORD Value.
5. Type PerfEnablePackageIdle for the value name.
6. Right-click PerfEnablePackageIdle, and then click Modify.
7. In the Edit DWORD Value box, type 1. In the Value data box, make sure that Hexadecimal is selected, and then click OK.
8. Quit Registry Editor.

4 - Make sure your BOOT.ini has this command in it, /usepmtimer to check, right click 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 looks like this

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOW S
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect /usepmtimer

Update:

It definitely fixed my problem and my computer seems faster as well.

Could this apply to hyperthreading p4's?
I find my 3.2e sluggish, random reboots, jerky scrolling

Chris - very possible, but seeing at that HTs are single core and not 2 physical cores this may not do it but there is probally a similar fix out there you'll need to find.

MNO - GREAT find. Glad you got the speed of your AMD up there..

You must spread some Reputation around before giving it to mnosteele52 again.

very cool of you to share it.

although my x2 is running smooth, certainly can't hurt.

Well I applied the hot fix and did the registry edit on my hT P4

Hmmm, seems snappier but I'll researve judgment and let you know, definatly booted faster

Well 24 hours and its running much better, appears to work well for Hyperthreaders also

Thanks for the info Chris, it makes sense to work for Intel CPUs with hyperthreading because as far as XP is concerned there are 2 CPUs. I will apply this fix to my fathers Intel and see.

Another thing I have noticed is my CPU temp has dropped a consistant 2 degrees Cell since applying this patch

well... tried this and do I regret it. Its causing way too much cpu usage than before and im running atleast 4*c hotter than before. I tried uninstalling the amd dual core patch, reversing and uninstalling the hotfix but cant get back to what was normal. Also, while playing a game, if I get a pop up of my wireless connection status the game drops to 10-15 fps until I exit and return to game.

How do I reverse what was left behind by the uninstall? I tried system restore and my processors are still being overworked and running hotter than the stock set up.

Do I do a windows repair? Reformat? Please help!

well both should be in your add/remove programs although to see the hotfix you'd need to check the box at the top of the selection screen that reads "show updates"

anything running that isn't necessary while gaming will effect performance....

The hotfix is uninstalled, the patch is uninstalled.

Processor seems to still be affected. Still has me running hotter than normal with an excessive amount of cpu usage.

I would normally never even come close to 50% usage or 50*c with the FLAME icon from speedfan going off.

note* when I do a system restore, despite being uninstalled, windows makes a back up copy of the AMD DUAL CORE OPTIMIZER and {587178E7-B1DF-4945-9838-FA4DD36E873C}

Whats up with that and should I just search for this file and delete it? Is this the cause for the change in my pcs behavior?

are you sure you're adware/spyware free ?

The dual core fix shouldnt be causing your CPU to be under more load.

Ccleaner
adaware
spybot
super antispyware

calcul0n · Post by **calcul0n** » Thu Feb 15, 2007 1:27 pm

Positive im junk free.

Its a new pc i built from scratch.

Tuesday (running fast and cool) I installed Avast, AdAware and Spybot S&D.

Running perfectly fine with those 3 doing there thing.

Wednsday (running fast and cool) I installed the AMD DUAL CORE PATCH and the Win XP Hotfix and since then: 4-7*c hotter and games like Day of Defeat Source now take up 50% of cpu usage easy.

Pre-patch and hotfix - my pc barely blinked. 33-40%cpu usage if that.

Also, now when in game and IMs pop up or wireless status pop-up come up the game drops to 15fps and I can only move the mouse cursor like every other second.

the hot fix will not cause that.. and you have to make sure you install them two in the right order..but you have something on it causing a pull.

YARDofSTUF · Post by **YARDofSTUF** » Thu Feb 15, 2007 2:38 pm

Day of defeat should always max out at 50, as well as any other game.

Have you just installed the AMD driver or the optimizer as well or what?

Theres the CPU drive, the cool and quiet driver, and the optimizer from amd.

I have the Driver and optimizer installed and I don't have your troubles.
