I think he would have been better off getting an overclocked bundle from oc. im sure they would have easily got it up to desired speeds.
as i am the person who overclocks bundles and systems for OCUK, i would have to point out the following
we offer 4.2 commercially as EVERY 980x will do that speed easily
4.4 is achievable on nearly every 980X but requires a bit of skill
4.5 is about the max you can go [average] on water without it being chilled
4.6 or more is just asking for extra heat/powerdraw for minimal gains. sure if you want to go to 5ghz and break records then fine. but do this if you are an experienced overclocker as the only thing that will be getting broken is your CPU
the settings i gave the user were conservative for a reason. he is pushing speeds that require enough voltage to break/degrade the chip whilst openly admitting that he is new to overclocking.
i am trying to save him the heartache of bricking an £800 CPU
#8 so you can play bfbc2 32x 16x whit 60+ in frames i would like to se that. And metro to, so you alone can play everything maxed out i dont think so
like i said
i play BC2 at 1900X1200 [marginally bigger res than you] at full AA full AF everything on max bar HBAO and it runs at 60+
with my second 5870 it is 100+
i dont need my second 5870 for 1900X1200 but i have it anyway.
not too hard to believe.
as i said before im not knocking your rig, you came on here asking for advice on getting £2k+ worth of hardware up to stupid speeds then openly admitting that you dont know how to overclock. i offered advice because i can guarantee i will be one of the few users on here with access to that kind of hardware with enough experience to give you an informed opinion and constructive advice.
if you want to get defensive because i questioned your requirement for tri sli GTX480s to run on a 1080p res then be my guest, i was merely enquiring.
