Title: Tweaking PC again or sqeezing the orange dry Post by: listening on June 02, 2013, 08:09:59 pm After reading a lot of posts about XXHighend and Window 8 (will install a version next week) and not prepared to invest in new PC hardware I tried some additional Mobo/BIOS tweaks:
Tweaking down the CPU clock rate again I found some aditional parameters in the BIOS originally built in to overclock the CPU but used them to lower the clock rate. Hopefully I have reached the same low level as Peter. Tweaking down the clockrate of PCI Done via BIOS to the lowest possible value Tweaking down the clock rate of the North-Bridge Done via BIOS to the lowest possible value. The early sonic results are very promising.

Peter, how do you explain the results of a reduction in clocking ? Thanks. Alain Title: Re: Tweaking PC again or sqeezing the orange dry Post by: listening on June 04, 2013, 10:54:54 pm Hi Alan,
you've got to have the right feeling for it and I'm not sure to reach a stable point. Actually I've set the CPU clock rate, the Northbridge clockrate including the PCI clockrate to the same low internal frequency. The Hypertransport bus (AMD specific) is set to maximum clock frequency. The influence of this settings is lower than other XXHighend parameters. But I will try further to get the best out of the system ;) Maybe there is a bigger advantage with Windows 8.

The problem I have is that there are so many parameters with strange acronyms (there is not "Northbridge" notion in the BIOS for this pc), I fear I would do something that would screw up and then be forced to reset everything. I may have to go through experimentation at a certain point, but like you mention, I am not "in it" (curious yes, but not in a hurry) for the moment. Regards, Alain |
