Is my motherboard still alive? I have a dual-cpu motherboard (intel l440gx) with two pentium 3 cpu. Due to my stupidity, I burned both CPUs and I'm pretty sure they're totally dead. However, I'm not sure if the motherboard is still good. When I put the dead CPU in, the cpu fan still runs, the on-board network card still blinks, the hard drives still spins, the cd-rom still responds. But there is no video and the floppy drive doesn't blink. If I pull the CPU out or memory out, it will beep 4 times. There is no burned chips visible on the motherboard. I performed a CMOS clear but the result is still the same. So is the motherboard still good? I don't have two good CPU to give it a try.

Sorry for the delay, My primary hang point ishttp://www.investorshub.com/boards/board.asp?board_id=2128 It keeps me pretty busy. To answer your original question regarding the 13 or 14 multiplier, you actually get the very best results running the memory and the CPU at the same bus speeds. 13-14 multiplier is not feasable at the 200 FSB. Here are the PC Pitstop test results for the stock config when I built the machine. pcpitstop.com In the yellow box in the upper right hand corner you can click on test history and see all the results of the fiddling around with multipliers and voltages and bus speeds. The final test results are here pcpitstop.com Checkout the test details and hardware list sections to see how the machine is set up. On to your machine. First Kingston is not the manf rec'd memory for the Asus board. It is obviously currently working but the A7N8X can be extremely bitchy when it comes to memory brands. The official rec'd memory is Samsung PC3200 NON ECC. That is not to say that your machine won't overclock but if you have problems with stability at lower overclock speeds that is where I would look first. Second. Cooling. The board has a high temp shutoff to protect the CPU. It is very high and only kicks in to keep the Athlon from catching fire. It will allow unhealthy temps to run for a very long time. Even to the point of CPU thermal failure over time. AMD's warranty does not cover the CPU for thermal failure. I very much recommend that you invest in a SLK 900A heatsink and Tornado 80 fan before going very far up the overclocking scale. REMEMBER 55 Degrees and beyond will damage your CPU. 54 degrees is OK for a couple minutes. 52 degrees is OK. That being said, I believe the stock heatsink and fan should get you to 2200 cpu speed. BIOS settings to start should be 200 FSB. Memory setting to Aggresive. Multiplier set to 11. and jack the core voltage up one notch. If it is having stability problems check the temperature first and then jack the mem voltage up one notch. I wouldn't try to go any faster with the stock heatsink. Hope this helps. BT
