Hi all ! I have just finished the "up-grade" of my back-up PC, and I would like some hints about some LIGHT Overclock of it. My back-up PC basic spec is : - P4 2.8 Ghz (BUS = 533 Mhz) --> STOCK Cooler - Asus P4SDX MoBo (supports until P4 3.06 – 533 MHz) - 1.024 MB of DDR 333 PC 2700 Memory (4 sticks of 256MB each one) - Kingston KVR333X64C25/256 - 02 HDD’s : 01 HDD Maxtor 120 GB, ATA 133, 7200 rpm, 8 MB Cachê (Main). + 01 HDD Seagate 40 GB, Ultra-ATA 100, 7200 rpm, 2 MB Cachê (Slave). - Gigabyte Radeon 9600 XT Video Card (128 MB; AGP 8x) - ATX Case (from 2001), WITHOUT Lateral Refrigeration Holes. - An Exhaust Fan at the internal back of the case Well, I would like (if possible) to give a light boost in my PC above described (through a CPU Overclock). As I dont know well about this matter, I am here to ask for some hints about... So, my basic questions are: 1) I would like to increase my current CPU GHz to something around 3.0 GHz. This eventual increase (2.8 to 3.0) could be considered, in a technical language, as a Light OC, or not? Is it possible to do it, using STOCK cooler (and more one existing exhaust fan), and in a SAFE way? Really, I am not intending to spend more money with this PC, so, I am trying to do this OC WITHOUT any BETTER cooler ( I know that is, always, advised to get a better cooler when doing a OC; so, my bigger doubt is about to do it with the STOCK one...) I have tried to know if the STOCK Intel Cooler of the model 2.8 Ghz (533 FSB) is EXACTLY the SAME STOCK Cooler of the model 3.06 GHz (533 FSB), but I didnt find this information over the internet. I would appreciatte if someone can tell it for me... If the answer is YES (both would have the same cooler), so, I think that I wouldn't have problems by this side... 2) If it's possible to do it, what I need to change into BIOS to achieve the 3.0 GHz frequency? I need to say that, if possible, I wouldn't like to change the voltages, because I have read that it can be dangerous, and I want to do all the process in a VERY SAFE way... 3) My current PSU have nominal capacitance of 450 W. I dont remember it's brand (and I do not like to open the PC case), but I am sure that it is NOT a First Class brand... Can I have problems by this side? 4) Should I try to change the DEFAULT Latencies (2.5 3 3 7) of my RAM memories? I can say that, without any OC, I run smoothly my memories with the latencies 2 2 2 6, without any trouble. If I OC, would my memory have some REAL danger of damage if I maintain these lower latencies? 5) I have noted that my CPU, when I am playing heavy games (I love racing games) for one hour, sometimes reach 64oC/ 65oC of Temperature (but these temperatures drop quickly when I stop of play, perhaps because of the assistance of the exhaust fan...) . Into the Asus program, which controls the MoBO and CPU temperatures, there is a upper limit of 72oC... I am afraid about to damage the CPU if I OC it, because everybody knows that OC generate more heat ... Is it a real potential problem? 6) If something goes wrong, would I have the possibilty of return to the Default Settings, or I can have something fried without any previous warning? 7) As it is my bac-up PC, I generally do not use it in a intensive way; sometimes, it stay without any use for 2 / 3 days... Would this eventual use of it, with this OC, reduce the lifespan of my hardware? 8) Last, but not less important question... This eventual OC of my CPU recoup the potential danger that I can have doing it? In the REAL World, would I have some effective gain of performance? Well, with these basic observations and questions, I would like to hear some opinions about my wish of have a Light ( if I can say this word...) OC ... As I am intending to do it (IF POSSIBLE), in a VERY SAFE way and with STOCK CPU Cooler, I need some expert opinions to know if I can continue with my attempt or desist now, before any potential damage. I think that the crucial question is: does the P4 2.8 GHz (FSB=533) have the SAME STOCK Intel Cooler than P4 3.06 Ghz (FSB=533)? If YES, I think that (It's a NON Expert opinion) I could try to do it with a good security headroom...; right? Thanks in advance for any hint / useful information !!
