Hi, I've had my CPU(Pentium 4 640 3.2Ghz with HT) for about 2 years. Just out of curiosity I ran CPU-Z and found out core speed was 2810MHz. The bus speed is 200MHz with a rated bus speed of 800MHz. Do you think I don't have my mobo utilized right? Or that my CPU lifespan is getting low? My mobo is Asus P5LD2-Deluxe. Here's part of the CPU-Z log. Processor 1 (ID = 0) Number of cores 1 Number of threads 2 (max 2) Name Intel Pentium 4 640 Codename Prescott Specification Intel(R) Pentium(R) 4 CPU 3.20GHz Package Socket 775 LGA (platform ID = 4h) CPUID F.4.3 Extended CPUID F.4 Core Stepping N0 Technology 90 nm Core Speed 2809.9 MHz (14.0 x 200.7 MHz) Rated Bus speed 802.8 MHz Stock frequency 3200 MHz Instructions sets MMX, SSE, SSE2, SSE3, EM64T L1 Data cache 16 KBytes, 8-way set associative, 64-byte line size Trace cache 12 Kuops, 8-way set associative L2 cache 2048 KBytes, 8-way set associative, 64-byte line size FID/VID Control yes FID range 14.0x - 16.0x VID range 1.116 V - 1.420 V Thanks.
