I have recently overclocked my CPU reflect a 1.7 Ghz speed. Can I go higher and if so waht are the safe CPU/System Temp. limits???

Again, overclocking is not an exact science, it often requires experience, trial & errors and some luck. And since results typically vary from one system to the other depending on other components in the PC and the user's OC skills. It is hard for anyone here to tell you precisely when to stop, unfortunately - you'll have to discover that all by yourself. However, with that said - it is almost impossible to "fry" your P4 CPU by overclocking it, because it's got a thermal protect mechanism built in that throttles the CPU if its temperature gets past its threshold level.

its all about the OC'ing skillz... Prescott 2.8Ghz Oc'ed @ 3.6Ghz; 5:4 ratio Abit Is7-E Motherboard, i865-PE Chipset Muskin pc3200 Enhanced, 412Mhz; 2.5-3-3-6 Pny 6800nu; 430Mhz 820Mhz; 16p,5vp Two 36Gb Raptors in raid0 a

Well, We all know what the causes and what can happen to a overclocked cpu, blah blah. but its all about practice. Stuff can happen, and 98% the time, it is reversible. So, since noone explained it here. I will. Overclocking a processor means enabling it to operate above the manufacturer's specified frequency. Many Internet sites provide instructions for overclocking. Processor manufacturers and many computer experts believe the slight gain in performance (only perceivable on CPU-intensive software) isn't worth the expense or considerable risk. so now here are steps on how to do it: * STEP 1: Get whatever tools you need: screwdriver, needle-nose pliers, motherboard manual, cooling hardware, etc. * STEP 2: Find out whether your motherboard can be adjusted in the BIOS setup, with jumpers or not at all. * STEP 3: Find out clock-speed limitations of the motherboard. * STEP 4: Run all Windows and any third-party diagnostic applications you have. Fix all system problems. * STEP 5: Make a complete backup of your system, documents and applications you don't have on CD-ROM. Do not overwrite these copies. * STEP 6: If you have a BIOS-adjustable motherboard, make changes according to your motherboard manual, and skip to Step 15. * STEP 7: Shut down computer. * STEP 8: Leave computer plugged in to surge suppressor. * STEP 9: Disconnect all peripherals from computer. * STEP 10: Remove cover of chassis. * STEP 11: Ground yourself to computer with any professional grounding equipment you have. Otherwise, ground yourself by touching a metal part of the chassis. * STEP 12: If your motherboard has adjustable jumpers, locate the jumpers that control the CPU speed. * STEP 13: Use needle-nose pliers to change jumper settings. Move jumpers to positions indicated in your motherboard manual for the clock speed you want. Check the Internet for recommendations. * STEP 14: Install a CPU heat sink, heat-sink compound, and a specialty cooling fan, if appropriate and possible. * STEP 15: Put system back together, and reboot. * STEP 16: If computer does not boot, and CPU still works, try lowering the clock speed. If that doesn't work, restore the original configuration. * STEP 17: Check all functions, and run a CPU-intensive program. Now here are some warnings. * Be very careful that if you have an Intel Processor, overclocking your processor, will immediately void its warranty. And its easy to tell if it has been done so. * Prepare to deal with seemingly unrelated problems that can be caused by overclocking: destruction of other internal components, lost data, system and application crashes, and an inability to boot the system. Such problems can occur randomly or materialize well after you have altered your motherboard. Privacy? You have none.
