Cat Called Domino Posted January 6, 2002 Share Posted January 6, 2002 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.

MxxCon Posted January 6, 2002 Share Posted January 6, 2002 i think that value there is purely for legacy support. do you really belive that MS would release OS which doesn't work properly with such important part of a system?

Cat Called Domino Posted January 6, 2002 Author Share Posted January 6, 2002 Hey all I know is that I applied it and I get better performance with Photoshop and many other programs. I ain't Microsoft buddy...I'm just a guy who likes to pick up where they left off.

MxxCon Posted January 7, 2002 Share Posted January 7, 2002 yes, "i feel that i get better performance" doesn't cut it. give some scientific proof Link to comment https://www.neowin.net/forum/topic/9904-enable-l2cachein-windows-xp2000/#findComment-77343 Share on other sites More sharing options...
Cat Called Domino Posted January 7, 2002 Author Share Posted January 7, 2002 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!

steen Posted January 7, 2002 Share Posted January 7, 2002 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: http://www.planetmirror.com/pub/3dfiles/tw...akfiles/memory/http://www.planetmirror.com/pub/3dfiles/tw...akfiles/memory/ :) :) :) :) Link to comment https://www.neowin.net/forum/topic/9904-enable-l2cachein-windows-xp2000/#findComment-77504 Share on other sites More sharing options...
Cat Called Domino Posted January 7, 2002 Author Share Posted January 7, 2002 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.

mtgriffith Posted January 7, 2002 Share Posted January 7, 2002 You can find out how much L2 Cache your AMD processor has by running the AMD CPU Information Display Utility from their website. http://www.amd.com/us-en/assets/content_ty...ies/cpuinfo.exe Link to comment https://www.neowin.net/forum/topic/9904-enable-l2cachein-windows-xp2000/#findComment-77553 Share on other sites More sharing options...
Big_Mark Posted January 7, 2002 Share Posted January 7, 2002 ok it is 256 what would be the number I enter in the registry? Link to comment https://www.neowin.net/forum/topic/9904-enable-l2cachein-windows-xp2000/#findComment-77556 Share on other sites More sharing options...
Cat Called Domino Posted January 7, 2002 Author Share Posted January 7, 2002 it should say "SecondLevelDataCache"=dword:00000256 after you're done. Just enter 256 after going to modify by right clicking.

Big_Mark Posted January 7, 2002 Share Posted January 7, 2002 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.
