Keep us posted with benchmark results and OC screens please
Will do.

This was a single card run in XP.

slaWter's right, Muppet. 1.5vCore on a 45nm chip really is far too much for anything other than benching. Also, there has been talk of high VTT voltages ****ing 45nm chips. Be careful, bud

Uber nice rig, though. I wouldn't go much over 1.4vCore for normal use.

Intel's recommended vCore is 0.85V – 1.3625V and 64.5C max temp.

You should benefit from a higher FSB and lower multiplier, too. Try 450 x 9 (4.05Ghz) @ about 1.4vCore.

You are right. I'm just testing to see what I can get out of this chip. 4.0 is only 1.34 volts. I think i'll make that my 24/7 clocks.
I have read about the FSB Voltages doing bad things. Because of this I never put it above 1.3

I managed 520Mhz FSB at just under 1.5v NB I'm running 450Mhz @ 1.44v now but i'm thinking of dropping it to 400Mhz for that reason.

Anything over 500FSB on a 780i is really really good. Very impressive.

That's with the (quite poor) air cooler. Is your NB water cooled? If so I wouldn't worry at all at 1.4v NB. Should get you 400-450Mhz easy. These 780/790 NB chips can really kick out some heat.

No the Chipset isn't watercooled. The 790i runs alot cooler than my 680i and 780i ever did.

Default Re: Intel now shipping 45nm Yorkfield CPUs for next week

Im very happy with my "3ghz" Q9650
Its very expensive.. but its very fast and incredibly good processor for overclocking ..

i have mine at ~ 4.2Ghz on air without being too hot . but it can boot windows up to 4.5ghz... albeit too hot. Im really sure it can do beyond 4.6 with more tweaking and water cooling.


the performance for what i have seen in real 3d benchmarks is nothing less than impressive since its on par with latest Apple OCtos.. (at default speeds) that cost an arm and a leg and comes with two yorkfields and up 16gbs of ram.
