Well yesterday my old SL2S9 P200mmx that had been happy for years at 250(2.5x100) just refused to work stable. System would lock at different places, sometimes just after logging on. Set it back to 200 and she worked fine. Hmmmmmmm guess she just got tired so I replaced it with a k6-300 that was given to me for nothing and set it for 3.5x100 and all is well. If you hear taps at midnight you'll know I'm in the back yard putting the ol girl in the ground. RIP ol Pentium. Now is it me or do the retail Pentium HSF's look like little black ORB's....wonder how I can mount this on a vid card.
