Did you try the memory in the slots as per the manual to get dual channel ? Sometimes you need it in alternate slots not side by side.

Yes that's it. You can't make the system hold on the post screen unless there's an error. Have you got the latest version of CPU-Z? It may not support that chipset yet..

The Pause key usually works... if you can hit it quick enough! Or Ctrl-S (I think). Easiest option though is turn of Quick Post in the BIOS, you'll get a few seconds to read while it checks the RAM.

Re: asus p5k mobo cannot get dual channel ram working..help

Thanks guys its sorted i downloaded latest version of cup-z and it states it as running in dual channel
In the IA overclocking feature i set the memory to 800mhz with 2.2v yet cpu-z states each stick is 396.0mhz is that right ?
