Optimize XP for Dual Core

So would I need Windows XP 64Bit edition for this or no? It's not a problem, just curious.

Just to let you know I've been using Win XP 64bit and applied the amd optimizer and it did help dramatically, mainly for gaming issues where you would get stutters. So trust me it does work for 64bit XP.

Not sure about the registry tweak, but AMD Optimizer does help out a lot.

Applied the tweaks, system boots up almost twice as fast now.. infact it beats my network init, which it all used to do it at the same time.. now it's system boot up, everything loads, and then the network inits, and it loads in between 5 - 10 seconds. -Don't know if it's actually 5-10 seconds, it seems a lot less, I didn't exactly count it-

Holy crap, another good test, download a 1080p .mov, any, doesnt matter which. Play it, notice the performance, apply said fixes, AMD or Intel, play same video, take note of the performance. I can now play 1080p .mov files like they're nothing. I'm not sure if it was the AMD drivers, since the only ones I installed for my CPU was off of WinUpdate, or the AMD Optimizer, or the registry tweak, but something did the trick.

Well, I'm running SP3 and applied the tweaks suggested here - my computer hasn't exploded yet (running a Turion x2 @ 2ghz), and it might just be me but it seems like it's made a slight improvement. That's probably just me imagining things, though.

Either way, thanks for the guide.

Step 1, from reading this topic is only if your Explorer is crashing, right? I've left it out, because it's from 2006 and I don't want older files coming into my SP3 setup.

The registry and boot.ini I've changed. Hopefully this actually works (if it doesn't, then as long as it doesn't screw anything up).

none of my programs can use both cores fully at the same time I will explain the problem and then if someone can please tell me if I need to optimise XP, it is SP3.

If I am using an app or game that maxes my cpu (core 2 duo) then both cpus will run at about 50% each alternating up and down but total usage between them adds to 100%. If I goto task manager and set cpu affinity for the app/game to 1 cpu only then that 1 cpu then goes to 100% normally and the other cpu idle. But if I switch it back to both cpus then they both goto about 50% each. I am baffled by this as I have some apps that saturate cpu and they only using half the power in my system, any idea why this happens?

Only apps written for multiple cores can max out mulitple cores. These tweaks work because they help divide the workload up more evenly across mulitple cores. Whereas XP on it's own, tends to send all of the work to a single core.

Pretty sure it was AMD Optimizer. I too have installed it and it seems to have noticeably improved overall performance. AMD's best software. :D

2. Registry Tweaking

(k let's make this clear, the next two steps i take no responsibility, if you eff up your system that is your problem, but this DOES work, make sure you do exactly as I tell you)

Go to the registry edit via the run command. (Windows key + R---> type in "regedit"). Look for this HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager and then look for the key (or folder) named Throttle. If it's not there, right click Session Manager, go new and then Key. Name it Throttle. In there there should be a DWORD called PerfEnablePackageIdle make sure the value = 1. If not, make it say 1. If the key is not there, create it. Right click an area in that box, and go new DWORD. This will increase performance A LOT.

I didn't have a folder 'Throttle', so I created it. But it did not have a DWORD by that name. I'm assuming that the DWORD is this:

@Green- Gah, I don't know why I didn't read it the first time. It's like it wasn't there.

Also, since it isn't mentioned, should I set the Base to numerical or hexadecimal?

Doesn't matter. 0 and 1 are still 0 and 1 in both Decimal and Hex :p

      Here's a good laugh for you then. My brother, his girl friend and my son all have the Galaxy A15 5g and they are working absolutely great. My wife and I both have the A16 and they are working great also. Maybe you are laughing at the specs, but for under $100 I would hope you aren't expecting much.

      We need a game update frequency setting. * Right now your recent games will be auto updated overnight, and your unrecent games won't be updated. The bifurcation of recent and unrecent is fine, but we should be able to control the update frequency for both, with any of the following options: 1. Don't auto update 2. Auto update weekly 3. Auto update overnight 3. Auto update immediately (push) i.e. When I'm playing a lot, I want my recently played games to have push updates, so if a dev releases an update at 4pm, it's already downloaded on my Xbox by the time I get home. The current overnight cadence leaves a lot of wasted time waiting for updates on slow connections. My infrequently played games in ok with deferring to overnight, or maybe weekly, but let the users control their frequency. Basing it on data and last played sounds smart but ignores the human reality that often when I'm busiest and have the least time for games is when it sucks the most to come home and find a huge update list waiting for you.

      Genocide is intent to exterminate and both the Israeli government AND its people openly declare, even boast about their intent to exterminate Arabs. This society of sick psychopaths has even made songs about it. Zionist means believing Israel should exist as an religious ethno-state where only Jews have rights and everyone else is second class citizen. As for the blood libel thing, we already know zionists get off on killing children. We also know Israel is a safe heaven for all the pedophiles and rapists of the world. Honestly, after what we saw in the Epstein files, I wouldn't put anything past this depraved death cult. Of course all atrocities committed by tHe wOrLds mOsT mOrAl aRmY are always "unproven or taken out of context". Unfortunately for them, their soldiers are dumb enough to leave a trail of their war crimes all over social media. Then again, when you live in a society that's obsessed with death and destruction, posting videos of yourself in the act of ransacking homes and desecrating religious monuments earns you brownie points I guess. Israel is the only society in the world where people come out on the roads for the right to **** prisoners. Also claiming that the BBC said this and AP said that without so much as a link has gotten me curious. Are all zionists this dumb? I really hope you aren't getting paid for this because this is some low effort propaganda.
