Windows XP Tweaks - Not All Researched Very Well!
Posted by: [NT] on: 05/02/2002 05:28 PM [ Print | 4 comment(s) ] · 3090 views
Recently in the latest Windows XP tweaks, certain websites have made up this argument that Windows XP does not correctly detect the L2 cache size of the CPU.
Read more to learn more about this issue.
When this specific registry value that they point out is set to 0, it means that Windows will attempt to find the cache size from the HAL (Hardware Abstraction Layer). If it cannot get this value, it DEFAULTS TO 256K. In fact, from what the MSKB says, the value means absolutely nothing on "Pentium 2 and later processors". So there you have it, not all these 'tweaking' sites are what they're cracked up to be. I do this to warn you people about useless and shameful ways for them to promote their sites.

I'd just like to pitch in that in my XP & 2000 memory guides I've got up on Techspot.com (3dspotlight previously) I've got this up for ages 
"SecondLevelDataCache. For those of you with older CPUs (Pre-Pentium 2 basically), this DWORD Value specifies the amount of L2 (Secondary) Cache on your CPU. Normally this amount will be determined via the HAL, although with older CPUs with off-die L2 Cache this may not be the case. Those with semi-modern CPUs (Pentium 2 or newer) should leave this set to 0 (As should those with Multiple CPUs). If you have greater than, or less than 256KB of L2 Cache on your (old) CPU then Right click on this entry & select Modify. Select the Decimal button & enter in the amount of L2 Cache available, e.g. If you have 512KB L2 Cache then enter in 512." Snarf  |

Certain others that I have read have not, however. They specifically say "Windows XP DOES NOT DETECT L2 CACHE SIZE CORRECTLY" heh..Good to know that someone does some research though. |

Yeah, I know what you mean though, I've noticed that too, ahh well. Nothing affects performance more than a placebo. |

Actually another BIG mistake that I've seen MANY make are A. Showing how to disable POSIX (& OS/2) under Windows XP & 2000 by deleting files - can't be done due to Windows File Protection. You have to edit the registry to do this (have that covered too ).
B. Other similarly post how to disable WFP in Windows XP the "same" way as in Windows 2000 pre-SP2. Again, can't be done. |
