Overclocking i7 and using crossfire

[lake2k]

Hi Am using an intel i7 which i have had oc to 3.8 was quite stable for few days were before that was unstable we issues of oc failure then crossfire not finding 2nd card, i mean in windows i saying a driver aint compatible we one of my video adaptors, then i reset bios and all my problems were solved

Then last night oc started failing again and so did crossfire, usually after a reboot and has been after testing we 3dmark 06 or vantage

Am using 64bit vista we a asus p6t and 6gb of gskill ram in triple setup
and intel i7 920 watercooled

Has anyone had any issues with crossfire failing with ati 4850s, or any guidelines for clocking upto 3.8 or even 3.5 it may just be me voltage am going wrong on maybe and just give up now for few days

Any advice be helpful

Thanks

Don't really understand the problem, are you from the north? we = with, were = where?

Boot up machine, enter BIOS.
Set everything in BIOS to default settings i.e remove O/C.
Save & Exit.
Shut Down.
Remove 2nd card.
Reboot.
Remove/Re-install ATI drivers.
Check single card has been installed properly and is recognised.
Reboot into Windows.
Shutdown.
Install 2nd card.
Reboot
Check 2nd card is recognised. If not, CCC or Drivers not removed properly/installed correctly, return to step 4.
Reboot.
Go into BIOS, try O/C'ing.

If O/C'ing is affecting your crossfire settings, something is wrong that I don't know about.

(I am not a pro, I could be wildly wrong, it is just what I would do)
