5Ghz the new 4Ghz.....I don't think so.

but, 4.5GHz will most likely be the new 4.0Ghz.

So far all the reviews indicates that a monkey can change basic bio functions and run 4.5Ghz with Sandy Bridge.

4.0Ghz on 1366 i7s is ridiculously easy to run stable. So expect Sandy Bridge will be ridiculously easy to do 4.5ghz.

ridiculous voltages - OC3D needed almost 1.56v for 5 ghz(4989mhz) on the 2600k.

What would be a more realistic 24/7 OC just wanna hear some opinions =)

Are the 32nm chips able to handle more voltage? OC3D showed load temps @ 1.56v were 74c (on a D-14 air cooler with 3 fans mounted). Impressive considering the massive voltage.

Remember half most of the reveiws are from before the Bios fix. Origionally only the intel Burrage had "Internal PLL voltage override" so they were the only boards posting +5ghz overclocks. Gigabyte and others updated thiers yesterday. So any benches older then 24 hours that are not with the intel board really arent as good as they could be.

One of the guys here got 5.5ghz at 1.536 volts after the fix

From Hardware Cannucks:

Quote:
Based on a third-party's extensive testing of 100 retail D2 stepping processors, this is how Sandy Bridge is shaping up on the overclocking front:
Approximately 50% of CPUs can go up to 4.4~4.5 GHz
Approximately 40% of CPUs can go up to 4.6~4.7 GHz
Approximately 10% of CPUs can go up to 4.8~5 GHz (50+ multipliers are about 2% of this group)
however, They dont say what voltage they have considered as the limit for the testing.
