Hi to all. I built a new rig 2 months ago with the folowing:
- P5K Premium
- E4500
- XFX 8600GT
- 2GB DDR 800
- Samsung 320GB SataII
It has been working fine up until 5 days ago. I was using BIOS 0302, with C1E disabled, FSB 255x11, 1,288v...
One day it begun to have trouble POSTing like many other p5k´s that we read about. After trying a lot of different things it started to POST again (90% of the time!). One of the things that I did was to update to the new BIOS 0504 using ASUS Update (I know, I know it was risky!). After runing for a while without any issues I went back to the BIOS to go back to my original oc and back to AHCI mode. As I rebooted I noted that the FSB was the only variable that did not change. I tried going back to Auto then back to manual... no luck the FSB stays at 200. After messing with this for a while I found out a couple things about my board (prob true for other ASUS P5K´s). When you reboot after changing Voltages, FSB, dividers, or after a "Overclock Failure" it will go OFF and then ON again, instead of just rebooting like when you change other settings that don´t need a power off.
The problem was (IS) that if I change just the FSB it doesn´t power off, therefore it doesn´t change it. So what I did was make it think it had a "Overclock Failure". I went in the BIOS and hit "Exit and Save Settings", and when it rebooted I turned the PSU off. When I turned it back on it gave me the "Overclock Failure". So I went in the BIOS, changed the FSB and "Exit and Save Settings". It powered off and on ... and the FSB change stuck!!!
It´s been working but I would like a permanent working solution, something that makes it easier to change the FSB, like it used to be.
- Shoud I flash my BIOS again (0504)? The only thing that doesn´t seem to be working is the FSB thing and the ocasional no POST.
Any input would be greatly appreciated!!!
