Gigabyte EX58-UD5/Extreme Discussion Thread

First of all, you might need lower temperatures than you have now to achieve such high uncore clocks. Secondly, 4GHz is near the limit for the ambient temps, so no wonder it doesn't boot up. And the last point, sure, it helps the memory bandwidth a bit, but getting higher CPU clocks would still give you a bigger performance boost.

You are right zalbard, but with my cpu at 4Ghz, I'm really near of it's limits...
( Edit : Now run 4,2 with more relax timings, and less Vcore... Have to stress it a little more)
Maybe I can reduce my Vcore a little more, in order to limit overheating,

But the thing I don't understand at all, is what's is happening when my MB don't want to boot at all ????
It is just "incompatible" settings (bads or insufficient voltages) ? , do it overheat....

Indeed, I've bought theses PC16000 modules in order to run them at 4Ghz uncore, so I really like to find the way to achieve it....

Moreover, I've found a proof of concept of 4040 Mhz Uclk on i920 C0 with Megahalems (AirCooling) - thanks pr@$r1g !!!
