Enable L2Cache.....in Windows XP/2000


Recommended Posts

From Tweaktown.com

The L2, or second-level, cache, is an integral part of your CPU. However, XP is very shoddy at detecting it, so setting it manually is sometimes necessary. It's easy to do, though, you simply have to navigate to

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory Management

in the registry and find the value SecondLevelDataCache. You must then adjust it to the value (in kilobytes) of the L2 Cache of your processor.

Look a here cowboy......you want a scientific proof.....then use "trial and error." Try the son of a b*tch out and if it don't do anything for you then that's your problem.....Not mine. I get much better performance.......what you still want numbers? Well too bad 'cause I got a life and I got stuff to do....girlfriends to do and that type of stuff. Give it a try. There's nothing more I can tell you!

I don't understand that the only way people can get rid of their own lack of knowledge is by being rude on various community groups.

By the way have you ever tried a utility (Free) which is called Mathlon that allows you to choose the speed of your L2 Cache where a lot of misbehaving is caused by the L2 is running to fast this utility will reconize most CPU'sbelow is the site you can download it from:

:) :) :)

some people just won't listen to the facts. fact: enabling the L2 cache boosts performance. There's no other way of me providing scientific proof than that. I didn't invent it...I'm just putting to use. And if you think I'm being rude....well then you try and explain to someone why Microsoft doesn't have it enabled by default. Hell who cares why!!! I don't work at microsoft and I don't care....just getting it to work is fine by me.

I did the tweak as you said I enteren 256 as decimal but when I open the thread again it goes to hex and it is 100.

That is the way it is supposed to be. The hex value is 100 and the decimal value is 256. If you made the hex value 256 then the decimal value would be 598.

it should say "SecondLevelDataCache"=dword:00000256 after you're done. Just enter 256 after going to modify by right clicking.

Well, if i enter 256 in Decimal...it doesn't turn out to be dword:00000256 , but instead it appears as:

"dword:00000100(256)"

???

    • So, do nothing basically, as long as you deploy Windows Updates? Pretty much yeah. Some Linux distros distribute update the secureboot certs as well, assuming you do use SecureBoot.
    • On one hand, YouTube videos are filled with so much fillers and the Youtubers intentionally speak slowly to increase video time and "engagement" metrics. On the other, Google's asking you to not stay on their site for longer. That's a win-win for viewers. So, I think it'll be axed or de-emphasised in the near future.
    • They'll just repurpose that for their AI trainings. Its never enough for LLMs.
    • Ubuntu gets second-ever snapshot release for Questing Quokka by Paul Hill Canonical has announced the release of Ubuntu 25.10 Questing Quokka Snapshot 2, a monthly development build that gives testers and developers a base from which to work on software for the upcoming release. Snapshot 1 was released at the end of May and Snapshot 3 is scheduled for July 31. Notably, the release date of Snapshot 2 and 3 have moved since last month. The Snapshot 2 update is available for various Ubuntu spins, such as Kubuntu and Lubuntu. To download, head to Ubuntu CD Image and go to the link for the version you want, such as ubuntu/. Once you’ve picked, go to releases/ > 25.10/ > snapshot-2/ and download the appropriate image for your computer - most people will want ‘64-bit PC (AMD64) desktop image’. The announcement mentions that these snapshot builds are not production ready, so you should not be installing them on a machine you use to do your work and daily computing. Canonical said that these builds should be seen as “throwaway artifacts”, whatever that means. If you’re an Ubuntu developer, you should submit your changes in the Ubuntu archive by July 28 to see it in the third snapshot. If you make any changes, Canonical asks you to update the Release Notes with the updates that you have worked on, so everyone knows what changed. Speaking of release notes, Canonical has been updating them incrementally. So far, we know that GNOME 48 is being used alongside the Linux 6.14 kernel. The use of GNOME 48 means that Ubuntu 25.10 only supports Wayland sessions as X.org has finally been dropped. Wayland has been used for a while on Ubuntu, so most people shouldn't have any issues as a result of the switchover. If you want to try out Ubuntu 25.10 Snapshot 2, you can find the download links over on the Ubuntu website. Just remember, these are not intended to be used on production machines!
