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

[Cat Called Domino]

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.

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]

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]

yes, "i feel that i get better performance" doesn't cut it.

give some scientific proof

[Cat Called Domino]

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 have AthlonXP 1600+, how much should i set it to?

512? 256?

[Cat Called Domino]

256

[hotrod]

Mxx he ain't doing nothing other than passing on a tip he picked up along the way........ wether you use it or not is up to you. but your rude comments are uncalled for. if you don't care to know about tweaks that people run accross, maybe you should visit another board?

[hotrod]

what about pIII's??

i have a PIII 866EB?

[Cat Called Domino]

Any P3 is 256.

I have an AMD T-Bird 1.4 anyone know what I should set me cache to?

[Cat Called Domino]

Yet again......the AMD T-Bird is 256K L2 cache

[mtgriffith]

You can find out how much L2 Cache your AMD processor has by running the AMD CPU Information Display Utility from their website.

[Big_Mark]

ok it is 256 what would be the number I enter in the registry?

[Cat Called Domino]

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

[mtgriffith]

Use decimal and set it to 256.

[Cat Called Domino]

yup.

[Cat Called Domino]

I just checked it out......you're right. Go with the decimal. Sorry about that folks....

[mtgriffith]

BTW thanks for the tip. Mine was set to 0.

[Cat Called Domino]

no problemo

[Big_Mark]

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.

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

"dword:00000100(256)"
