Asus P5K-SE + E6300

[Gazmondo]

Hi, I seem to be hitting a wall with an overclock... My max seems to be 333FSB (x7) up from 266FSB (x7), anything above that and I get an error on POST saying overclock failed. My ram is rated to run at 800mhz, and I set it in the bios to run at just under that (due to the FSB:RAM ratio's available to me).

As I'm new to overclocking, what does this mean? Is this the max my ram/cpu/mobo can take? Or do I just have to up some voltages?

Cheers

You could try setting fsb to 400mhz, drop the cpu multi to 7 (from 8) ram at 1:1 (its then running at 400mhz also) give a slight increase in Vcore say 1.4V. "lock the pci-e bus to 100mhz", ensure your memory voltage is set to 2.v Vdimm, That'll give you 2.8ghz. Try that and see if the pc boots ok and run orthos to check for stability. That'll check that the cpu clocks ok, you can try to raise the fsb a bit higher to try for 3.0ghz, but the ram is gonna be the limiting factor here.
I've had a few e6300 cpus and they all did 2.8ghz at least with those settings. Another thing to try is if you have a bios option called "usb legacy support" disable it, this caused a few failed overclocks until someone told me to try this.

The max cpu multi is 7, no option for 8.

Right I will try those settings. My ram is rated to run at 1.8v, so should i stick with that?

2.8ghz sounds fine to me, maybe push to 3ghz once I get some pc8500 ram over my current pc6400...

What is usually the cause of that error then? Is it lack of volts to cpu or northbridge or something else?
