hey how about mine?@ lem02
Well there is good and bad news. But first understand that any OCing can potentially fry your system beyond repair and you must take full responsibility alone for your actions and results
The good: your mobo is a pretty good OCer for a 400MHzFSB-CPU-only mobo. Your FSB is adjustable in your BIOS as is your CPU voltage. Your CPU is also a later revision(D0 stepping) so it will OC better than earlier versions. Your mobo manual says a 20% OC to 120MHz(1.8GHz) is possible with the right components, so they at least support OCing. There is also the BIOS 'load turbo defaults' which probably just tightens memory timings a bit. Couldn't hurt to try it and see what it does. You will need to get some benchmarking programs like 'sandra'(sig) to record what any changes you make do to iumprove performance. Try tweaking just one thing at a time and then restart and run the benchmarks, shut down then tweak one thing and benchmark, etc. It takes time but it is the only way to see what difference each setting makes either good or bad.
The bad: 1)Your CPU temps (under 'sensor')at 70C is WAY too high! You need to redo your HSF/CPU connection. Clean off the old stuff and follow these instructions. Take your time and do a good job. ArcticSilver5 is the best thermal paste available, but good HSF/CPU contact is mandatory. This must be done every time the HSF is removed. After redoing that, recheck your temps under stress using 'Prime95'(sig). They should never go above 55C(lower is better) if you applied the thermal paste correctly. Your mobo temps are low so you probably have OK case airflow. Your HDD temps seem a bit high at 37C, so if you do not have a front fan, you might want to get one.
2) Your BIOS manual sucks so I can't see what is under the 'advanced chipset' heading. If there is an option to 'lock' your AGP/PCI speed to 66/33MHz, do it. If there is no AGP 'lock' your OC will be limited to no more than 10% without becoming unstable.
3)You have no option in BIOS to change you Vdimm(voltage to your RAM to aid in OCing). Your PC2100 RAM may not like being OCed and will likely be the thing that prevents any serious OC. It has an SPD of: @142 MHz 2.5-3-3-7 (CL-RCD-RP-RAS) and
@ 133 MHz 2.0-3-3-6 (CL-RCD-RP-RAS). So it is capable of at least a small OC with the looser timings. Investing in one stick of PC2700 or PC3200 would help considerably, but it may not be worth the extra money as you may not going to see huge OCs anyway. With your current RAM, you might see 1.8MHz(at best unless it is 'miracle' RAM) but with one 512MB stick PC3200 you might get 150MHzFSB=2.25GHz CPU(watch your temps, you may need an aftermarket cooler or a faster'louder CPU fan) with memory speed of 200MHZ=PC3200. So your memory would be running stock speed! So we will assume you are looking for a $$$-free OC.
So for OCing advice, which is pretty basic generally applied OCing procedure and after you get your temps under control I would first benchmark your system with sandra and everest and HexusPiFast at stock speeds(no OC). With Sandra, record the separate scores as well as the combined. Then I would try the 'turbo default' settings and benchmark. Then I would try the AGP/PCI lock, and OC the FSB a 2 or 3MHz at a time and benchmark between each change. When your system fails to boot or pass the benchmark tests. I would turn off the 'turbo' setting and continue on. When it fails again, I would back down to the last stable OC and loosen the memory timings to the 2.5-3-3-7 settings and try again increasing the FSB a bit at a time. Continue the benchmarks as they are the only things that will tell you if OCing is helping or hurting. With your RAM you may only get a small OC before instability prevents further progress. The '142MHz' for your ram translates to about 103MHz of FSB speed, so you may have to loosen the memory timings rather quickly. You may also have to crawl at 1MHz addition at a time when you get near the peak OC. There aren't any memory/fsb ratio adjustments in your BIOS to help with that problem unless they are in the 'advanced' settings and listed in the manual. If there are such settings, report back here.
OK I am stopping now. I have waaaay overanswered as I have gotten carried away for the 300MHz your are going to see with your current components. Consider getting one stick of 512MB PC3200 ram if you want more from what you have with minimal investment. and watch your temps
Keep us posted with your progress
