Sapphire ATI HD 3870 ALL YOU NEED TO KNOW (OC'ing)!!!

[laragirl83]

be careful raising your PCI-E if you have SATA drives. i would imagine you could corrupt your OS if you set it too fast. i tried mine at 120 once and couldn't even boot into Windows. i put it back to 100 and everything appeared okay. i decided to leave it at 100 since then.

Yes, I have done a lil' searchin' in the net about this question, and found its best to leave it at 100MHz.

It really depends on your chipset. The older chipsets (965 and lower) aren't able to handle higher pcie frequencies but the p35 and x38 chippies can.

120mhz is pushing it though, I would recommend 107-115 to help stabilize OC'ing issues.
