I had CPU-Z on my pc before I reinstalled Vista, so decided to download it again today. Now I must say, I've never seen anything like this on CPU-Z: my CPU clock speed keeps changing: 1004MHz, 1808MHz, 2009MHz, 2210 MHz, 2411MHz... Also the CPU mulitplier, which is supposed to be 12, changes to 5 (So the CPU frequesncy becomes the same as the LDT Bus (HT LINK))... CrystalCPUID shows the normal clock (2,4 GHz), the stock speed, and normal Multi (12)...
Any ideas? I'm going to overclock again after a 2,8 GHz last year, but I'm waiting for my new PSU and better heatsink, coz the stock one's crap, it even overheats (+65°C) on stock frequency when stressed by OCCT...!!
