Also I had memory issues, after a lot of research it turns out that using 4 sticks of ram required that I drop my memory speed from DDR2-800 to DDR2-667 ... its Corsair ram and this is what was recommended on their forum!!. Dont ask me where on the forum, it was a good while ago.


(MCH = Memory Controller Hub = Northbridge)

Believe it or not that did occur to me but i didn't do it, will give it a whirl tomorrow night alright and let yez know how i get on, thanks very big for the info though

Any rough idea on the timings Sol??

I must post screens of the actual teak menu, might help putting the differwent names to whatever asus calls them

In my opinion non stable overclock's are usually down to insufficient voltage. Whilst booting failure is often down to the memory running too quickly.

It can be very hard to find the right balance between voltage and operating temperature, and of course this will vary slightly between seasons.

Also as your finding out the very best overclocks are normally with two sticks of low capacity memory. Again it's another balancing act between having a useful overclock 24/7 and an extreme overclock for the odd occasion and using the same hardware components for both!

Hope you get this sorted, if it were me I slacken the RAM timings some more 5-5-5-15-2T and see what happens. Another thing from the screen shots, if at all possible try not to use "Auto" settings. I always found that actually specifying the correct value where know was always better than letting it decide for itself.

Thanks RobMozza- the sickening part is i had it more or less stable @ 3GHz, it crapped becaouse of the RAM voltage i'm sure, but i havent been able to recreate that. As far as the timings, 5-5-5-15 was the setting, i don't think i specified 2T though, might be worth a shot.

I'm beginning to think it is the voltage because i ran it @ stock on PRIME95 and if it was hardware i'd imagine there would have been issues. So it seems i just have to work at the correct timings,volts, etc. It's just a pain in the a$$ to have to reset the CMOS evry 3rd or 4th time
