Intel sharpens Wolfdale's claws as E0 stepping dual-cores proves to be stunning overclockers



August should see Intel release its latest dual-core CPU model, the 3.33GHz Core 2 Duo E8600 and with it, a core update for the existing E8500 and E8400 that will see their steppings changes from C0 to E0. The Q9650 and a handful of new Xeons will launch. Early indications are that the new E8600 has plenty of performance potential. Overclockers at Taiwanese site Coolaler.com have managed to boot into Windows with an air-cooled E8600 clocked at 5GHz (using a 500MHz FSB, as the CPU has a 10x multiplier), although this did require a vcore of 1.6v. He later managed to clock the chip to 6.25Ghz using liquid nitrogen.

Both the E8400 and E8500 have already won the hearts of many overclockers, with many chips able to reach 4GHz with air-cooling with relative ease. Like the famous G0 stepping of the Core 2 Quad Q6600, the new E0 stepping dual-cores are already proving to be even more stunning overclockers than their predecessors. The E8500 with the C0 stepping currently retails for approximately £125 inc vat, so the new E0 stepping CPUs should be good value too, especially as you rarely see the benefits of more than two cores in games and applications. If you’re in the market for a new LGA775 CPU, they could well be worth the wait.

The E0 stepping will also feature a change in Platform Environment Control Interface (PECI) implementation which relates to the chip's thermal management and temperature readings; this may address some of the issues seen with the E8400 and E8500 with stuck thermal sensors leading to frozen temperature readings. We’ll be reviewing the new CPUs as soon as we get our hands on them. Also, bear in mind that the new CPUs will likely need a BIOS update so check your motherboard manufacturer’s website before buying one else you may find it’s currently unsupported.

If only i had an endless kitty of cash to frick around with mine a bit more.....

Asus managed to overclock this Intel chip up to 5.4 GHz.

Using a 3.2GHz Core i7 965 Engineering Sample, Asus achieved the overclock using its own X58-based P6T Deluxe motherboard, along with 3GB of OCZ triple-channel RAM. However, the real star of the show appears to be the CPU itself, as the overclock was achieved with a huge 27x multiplier and a 200MHz QPI base clock. While this is a decent enough overclock over the 133MHz default, we overclocked the QPI to 210MHz on the P6T Deluxe in our own tests, and we even managed to get 220MHz out of the Asus Rampage II Extreme (reviewed in Issue 65 of Custom PC), so this isn’t an exceptional achievement for the motherboard.

Awesome, i wish we could all use nitrogen

I am looking at building an i7 rig at the moment just checking out all of the reviews on the x58 mobos and i7 procs before I do anything.

This is quite a useful guide for you then.
