![]() ![]() ![]() ![]() They just don't have the preformance to clock ratio that the Core 2 Duo does, and the extreme overclockablity (is that even a word) of Core 2 Duo only widens the preformace gap between the two CPUs. The Athon64 x2 overclock well, the last one I had in my primary system was overclocked by about 40%, and they do well in MAME to a point, but they can't jump the preformance gulf between what is needed to run most ROM and what is required to run all ROM (well almost all). Those tempatures look normal for a stock setup, I would expect lower temps if you were using an aftermarket cooler, but it depends of the room temp and the design of your case. The thing to remember is the Core 2 Duo is not an Athlon XP, the Core 2 Duo has great built in safeties for heat and will shut it self down if needed before any damage is done, just be smart about it, if you crank the FSB up to 600mhz and pumping 1.8v into your CPU and having it run a 75degs you would just be asking for trouble. ![]() Overclocking very safe as long as you don't push things too far, too much Voltage or heat and things can get nasty, A good heatsink & Powersupply are a must. Software overclocking has it's place, but it doesn't give you access to nearly as many setting to adjust, so it soon limits the level of overclocking you can achive, There are a number of bios features that needed to be disable before any form or overclocking is attempted, as they will cause stability issues with an overclocked CPU, so you end up having to change BIOS settings anyway so you may as well just do it all in BIOS where you'll get the best results. Then as long as you have a good aftermarket heatsink, you should be good to go. Memory is dirt cheap these days so it doesn't have to cost you the earth. Your memory will be your biggest issue, DDR2-667 like you have runs at 333mhz double pumped, so the 333mhz FSB of you CPU puts your memory at it's maximum stock speed straight away, say your aim for 4ghz with your CPU, for memory would end up almost 50% overclocked to get there, now that a big push for most memory and outside what I would rate as practical or save, you best option would be to be dump your current memory on a friend or family member with a PC in need of a bit more get up and go, and grab yourself a couple of GB of good DDR2-800 or better yet DDR2-1066 RAM. If you have questions as to what all those option in bios do, hit me with it, I'll do my best to explain, just don't ask me to explain it all at once. Overclocking is easy once you get to grips with the basics and get an understanding of what all the bios setting do, everything effect everything else, that's why you need to it in stages otherwise it becomes almost impossible to work out where you when wrong. Just take your time, and test each new setup with orthos as you go. Make sure your BIOS and Drivers are up to date before you start, I suggest using CPUz to get Live actual CPU speed & voltage information, the lastest CoreTemp is you best bet for watching CPU core temps, Orthos does a great job of stress you CPU & RAM to in limits (use blend test) and Windows task manager will confirm your CPU is at 100% load on all cores. If it pass that it should be ready to use, it you want to further test it warm up the room tempature to that of a hot summers day and test it again for 24 hours, if it pass that you good to go. Keep an eye on the CPU tempature and make sure it stays within safe limits anything up to 65 degs C is ok, over that is getting hot, and if it gets to 80 Deg C it will more than likely lockup before it can do any real harm, you really want it in the 20-30s at idle and in the 40s to low 50s at full noise. If done right and with a little luck it will be nice and stable at these settings, now you need to torture test your CPU with something like Orthos, to take it to 100% load and hold it there for hours, I suggest at least 10 hours for you final test with the PC house as it will be in operation. ![]()
