Athlon XP L2 cache not working??

I have an Athlon XP1600+ CPU on a Gigabyte GA-7ZMMH motherboard. I was
wondering whether there was any problem with the L2 cache; when I run
WCPUID Ver 3.0f, it shows the L2 cache Instruction and Data TLBs as "OFF"
for the 2M/4M byte pages. Is there any problem with the CPU or is this
normal? Also what WCPUID shows up for your AXP CPU's cache?

Here's a screenshot:

MCS, I haven't yet begun to diagnose the problem, because I'm not to sure whether there's a problem in the first place. I'm just alarmed that WCPUID shows it to be "off". What does WCPUID show for your AthlonXP CPU? :confused: What should it normally be?

Thanks MCS. That's exactly the info I was looking for. The reason I was so scared was yesterday, my finger got caught in the HSF fan while the system was running. That jolted the HSF and I was pretty scared about the CPU. Hence the anxiety. Good to hear that the CPU is good (as well as my finger ;) )

Ouch! Hope it wasn't a Delta Screamer!

I think it would be very difficult to precisely damage a specific part of the chip just by jolting it like that. Athlon cores have a habit of chipping or cracking which usually renders the ENTIRE chip off :)

LOL :), No it was a 5000rpm everflow on a TT volcano-5 HSF. Lucky me. :p

Yeah I know it's very difficult a part of a CPU, but I was pretty paranoid and didn't want to take any chances... the chip's perfetly okay now i guess....
