[Santa Rosa Refresh -> Montevina] M570RU 1066FSB Hard Mod successful

[kaltmond]

Hi all,

after reaching 4 hours this afternoon i finally found a way to hardware OC my X9000 @266FSB. The mod is directly on PLL clock generator ICS9LPR365DGLF. I tried before to set it in 1066MHz per SetFSB, but after restart the system won´t run, because PCI frequenz is too high, it´s not locked in 33MHz......Now is no problem at all.

The disadvantage of this mod is u must be sure your CPU & RAM can run that high. My Ram runs now @443.4MHz = DDRII 887.... And in order to get 266x13 stable, i also must do the vcore pin mod to get 1.3875v......

3DMark results here, overall is not good, still a old 7950GTX. But CPU score is a quite jump compare to stock.

Well how did you do it?!?!

[kaltmond]

Well, very easy, just reset the BSEL pin of Clock Generator.

Wow, very nice work!

[theriko]

can you post pics/guide please?

so no water cooling, but what temperature is it actually running at under load?

Gut gemacht junge...und wie geht's jetzt weiter????

Nice work there...

But be carefull with the PCI-e clocks... above 130mhz data corruption can happen on your HDD because the SATA controler uses the PCI-e bus.

Remember that the PCI-e frequency it´s not lockable via pin/hard mod, only the PCI bus...

I didn´t know that. Until now is everything fine.....
