Hey guys! I got an old rig here, and funny thing is that my P4 (socket 478) can't hit 2.8 GHz (the stock speed. It won't boot or anything unless I put the frequency multiplier to 125 (which 130 is default) and Voltage to 1.450 (Which 1.5 is default) Here are some of the other specs: 1gb DDR ram FX 5500 80gb hard Drive Asus P4 XTE motherboard. It was like this even before I removed the stock cooler. I saw that the thermal paste has run dry and I thought that it won't do anything bad. The fan also makes load Whirrrrr noises and it's normal temps are around 46-53 Degree Celsius. I was thinking of buying new thermal paste and re-apply it on the cooler, but since I'm getting a new rig I left that Idea out. Anyone knows why It can't hit the 2.8 mark? Thanks!
