Basically, an incident with a 2500+, a waterblock and a dodgy nut left me with a chunk missing form my CPU's core. Quite a large chunk - quite a few people were surprised that the chip still POSTed. Imagine a triangle, about 3mm tall, 5mm wide, taken out of the bottom-left corner of the CPU die. For those of you who havn't seen the core layout, this is in the corner of part of the Barton's L2 cache. Since the incident, my chip hasn't been able to go above an FSB of roughly 170mhz, and at stock speed performs at about 2300+ spec (Sandra reports it between 2000+ and 2400+). Since it's a Pre-week 39 AQXEA, and has hit 2.6ghz before, I really want to be able to squeeze some more juice out of it. My question goes out to people like ZapWizard. I want to be able to disable half my L2 cache, leaving me with 256kb of L2 cache, and essentially a thoroughbred core. I know that I can disable all the L2 cache (when I do, it overclocks fine, but performance sucks, obviously), but there's little point in doing that. If anyone knows how I can get around my "problem" (by disabling half of my L2 cache, or by any other means), then any help would be much appreciated.
