I just set it to 1024, on my dual core. Will that do or do i want the total cache of both cores? Thanks for the info though man!

You must be mistaken... I've seen benchmarks with L2 cache disabled in the bios and it's like a 10X performance gain when they enable it. Windows isn't that dumb that they wouldn't use the cache that people pay so much for.

At first when I read this FAQ I had my doubts it would actualy work, since that would have meant I've been using my AMD CPUs with the cache diabled all these years, from my duron to my newcastle. Lat night the first thing I did was to find the string and to modify it. Everything was just as it is written here, but after restarting I've seen there is no difference, no before/after WOW. I have no logical explination why that string has a default value of 0, but I'm sure that info is not used by anything, my CPU is working as it should.
Furter more, in the bios I can disable the L2 cache. I tested it with the L2 cache disabled and the results were catastrophic, it was like having to race a Formula 1 race driving a truck, so I'm preety sure that even on AMD cpus the L2 cache is enabled, up and running without editing this string

this doesnt sound right...i ahve an Intel P4 LGA775 630 and the value of that string is also 0. If your L2 cahe is enabled in bios then its enabled in windows. Simple fact: Bios setting overrule software settings.

I can't find this folder/entry in my registry. Any thoughts??

How old is your processor? Does it have an L2 cache?

This does NOTHING.

L2 Cache is always enabled unless you disable in BIOS.

No if's and but's. This does NOTHING.

This doesnt enabled your L2 it increases the reference list to use upto your L2 - only beneficail if you use large databases etc.
