I was owner of ati saphire 4850 toxic and q6600...and overclocked cpu to 3,0ghz ...no problem
yesterday i bought intel Q9550 and msi cyclone 4890 ..
first thing is that i have to wait 10-15 sec for picture on monitor ..samsung t240hd..
than after pic is shown i go to bios, overclock cpu to 3.4 and exit bios...
cpu came back to 2.83 but if i put another vga card everything work ok ..cpu is 3.4ghz
vga 4890 card also work after win is booted ..just cpu is 2.83
booth card have been tested in booth pci-x ports ...same thing in each situation ..old work ok new dont allow overclock
i have latest bios ..
can someone see where is the problem here ???
when overclocking ..i don't raise voltage, just increase fsb and adjust frequency of corsair dominator ddr2.
