Core i7 Supports Only DDR3 800/1066

Mobo integrators are ready to launch their Core i7 compatible products and in a couple of months we’ll get to pit the Nehalem CPUs against AMD’s Deneb. The first Core i7 specs were signaling the fact that Nehalem should be faster than Deneb, but a recent clarification shrouded all those expectations into a thick cloud of confusion. Fudzilla reports that the Bloomfield CPU (he first Nehalem CPU to hit the market in Q4 2008) will only support DDR3 800 and 1066.
Even the extreme edition 3.2GHz Core i7 which will be launched early next year officially supports only DDR3 modules clocked up to 1066 MHz. Intel didn’t mention anything about specific support for DDR 3 1333, 1600 or higher. However, it might be possible for motherboard integrators to come with a solution for this problem.
The guys over at Fudzilla also found out that the memory-CPU voltage has to be synchronized and this would mean that overclocking the Core i7 CPUs will be pretty limited. Current evaluations pointed out that you cannot go over 1.65V as far as memory voltage is concerned. DDR 3 1600 usually requires 1.8V or higher. Moreover, since the voltages have to be synchronized, everything over 1.65V is likely to turn your Nehalem CPU to a toast.
Bloomfeld won’t be supporting any DDR2 memories either. Only the motherboard integrators and chipset makers, excluding Intel, may be able to lift these limits.

Intel Core2 CPU Overclocked to 5.6 GHz

2007 saw quite a few overclocking records. I remember seeing a Core CPU pumped up all the way to 8 GHz. Pretty impressive, but now we have the Core2’s and the upcoming Core i7. It seems tht the Core 2 CPUs are not that susceptible to highly overclocked frequencies. The most recent record was set by Vince Kingpin and Peter Tan, who managed to overclock an Intel Core2 Extreme QX9650 to 5.6 GHz.
The two professional overclockers used the latest EVGA 790i SLI FTW motherboard which comes with digital PWMs. According to Fudzilla, they used 3Dmark 06 and Vantage and all things were stable. The Corsair Dominator DDR3 memory was clocked at 1864MHz, the board FSB worked at 467MHz, while the multiplier was running at 12X. This is enough for 5605MHz and they scored 32929 marks in 3Dmark 06. The system also featured a three-way SLI configuration with three GTX 280 video cards, which were overclocked as well.
The new motherboard is practically the same as the EVGA 790i FTW model, but comes with digital PWMs for extreme overclockers. EVGA is clearly determined to stick to high-end mobos and NVIDIA chips. The new board is said to be the first ever mobo to come with digital PWMs.
