Mainboard OC Failure

Odds are it's a combination of things. Any of the things listed below are most likely adding to your crashing

-You're ram is probably operating at it's max threshold.
-You may not have good enough cooling on the processor / ram.
-Your processor may need higher voltage to handle that large an increase in clock speed
-You ram also may need an increase in voltage
-Both of those above are dangerous btw
-Your motherboards south bridge may not be able to handle that much power
-depending on the specs of your system you may be maxing out your power supply
-you may be running too high of a fsb for the ram / motherboard to handle
-You may need to lower the multiplier to raise the fsb more or vice versa

First and formost though, cooling and voltage are going to be the key in extreme overclocking, which is what you are doing by raising the clock so much.

You need to read up on voltages related to overclocking the processor and ram and become an expert on the subject. Only once you understand the reasons why it works and how dangerous it can be to your hardware should to go any further. You also need to keep in mind your cooling setup. FSB overclocking overclockes all the of the other parts of the system too, not just the CPU, so multiple cooling fans that eliminate dead zones and target certain parts are a must. Make sure your processors heatink and fan are more than ok, in fact, you may want to consider some type or liquid, cryo, or heatpipe technology if you aren't already using them.

Like I said, you may need a larger power supply too, or maybe some stronger ram. You could try raising the rams cas latency. raising it by .5 may make the system bootable, or even stable. But this also will slow down the system, so you have to way to pros and cons and see how much higher you can go and if it's worth losing ram latency.

300mhz is a pretty large overclock, personally I'd be happy with that unless I was ready to invest in the parts and time needed to push the system past a 10% overclock.

Remember though, as good as an overclock you get on the system you still need a software tune as well. Even the fastest systems can get bogged down by an untuned windows. If you're not already, learn everything there is to know about tuning windows services and explorer.exe as well as registry tweaks.

You can literally cut a windows install down to half of the ram footprint as a default install and make it use very little processing power on the backend.


If you have any further questions post them here and I will do my best to reply back.

I hope this has explained your question in detail. If I've helped you please don't forget to rate me.
