So after my laping last week i decided to o/c today.

Heres 3.6ghz at idle....





And here under orthos load - i left it for 6.5 hours after this and temps rose to 49C...





Look ok? :)
I had some problems though. I started at 3.2ghz which was fine even at stock voltage but when i tried 3.4 ghz it wasnt playin ball. I kept upping the vcore until 1.52v but no joy. Then i read on another forum about holes in the fsb using a 680i mb and it was suggested i try going straight for 3.6 - it worked...
Runs fine, no crashes, 6.5 hours orthos stable, memory @ 900mhz linked/synked (sp, its late lol) 4-4-4-12 voltage @ 2.1.

Anyone with evga 680i mb know how i can see which bios version i have as the p31 bios is supposed to have fixed these so called holes in the fsb - mainly for quads but for duos too.

Anyway, im a happy bunny. My 2.66ghz c2d runs nicely at 3.6ghz....next up overclocking the gtx :p

System:
Evga 680i A1 mb
E6750 proc
OCZ platinum rev2 800mhz ram (2x1gig)
Thermalright UE cooler with 2x yate loons on it.
Antec 900 with the side fan in place.
OC 8800GTX gc with hr-03 cooler.
74g Raptor and 2nd 320gig hd

Not working out so well now :(
Answer to 1st question - temps were 49C after 6 hours of orthos - low i know but ambient is quite low in here prob 19C.
Vcore at 3.6 was actualy 1.44v in bios for the orthos testing - all was fine.
So i went to play Eve online but it locks/reboots within 30 seconds every time :( :(
I tried reducing to 3.5ghz etc but same thing kept happening. I unlinked the memory and ran it at 800mhz and loosened the timings to 5-5-5-15 but still no joy. Had to put it to 3.2 before it would play ball and it was still a little glitchy in EVE.
Gutted now :/
Not sure what to try next... increasing voltage never seems to help.. Im going to try 3.4-3.6 with volts up to 1.55 although im sure i tried that yesterday with no joy. MCP was at 1.55 (northbridge right?) ive put it to back to 1.5 now.
Thought it was all to easy ... I will try voltages like the 1.375 mentioned above too as it seems to hate the higher voltages, it just fails quicker! What the hells going on?
 
I just flashed bios to ver p31 and it lets me have 3.4ghz now.. at about 1.38v. 45C after 1/2 hour of orthos. Tried eve and its working so far. more messing *** see if i can get 3.6 stable in games.
