Is the vCore (1.45v for 5GHz) correct?
If so, nice.
Do you have any temps data?

[MikeMurphy]

Impressive speed but is 1.45v safe you think for a 24/7 oc?

[Oztopher]

Very nice.

Man, i got to get myself one of these, i can imagine even the worst clocking 2600K being better than my 860

[FlanK3r]

whau, can show more benchmarks? Cinebenchs at 5 GHz will be nice , wprime, some 3D marks? Thx for your post.

[Hondacity]

wow 4c8t

and super memory bandwidths..

[PolRoger]

Nice to see new tech Sandy Bridge.

I wonder what ~vcore is for a daily 4.5 on air?

OC 5GHz
CPU Idle 1.452V
CPU PI 1M~32M 1.392V

[thebanik]

So the rumors of no FSB/Bclk clocking possible is correct it seems. Sad times coming, but I hope there will be cheap unlocked processors like AMD

I will try more benchmarks next week, Thanks

[Toolius]

Awesome Stuff !!
Thank you very much for sharing !!
i was just wondering if there is any possibility to change the fsb/Bclk from 100 to like 102-105 as well for the last little bit of performance ?
Thank you again for sharing this ..
Cheers and kind regards.

[Chri$ch]

@ Toolius

yes is possible

[Toolius]

Wow..
Thank you for sharing that as well
Good to see that atleast a little bit is possible !!
Thank you very much Chri$ch ..
Cheers and kind regards !

FYI, 4.2GHz i7 920 (16x Uncore) has relative speed of around 32. Around 34.25 for 4.5GHz. Should be around 38.1 for 5GHz. Then again it would not go that far.

[Pt1t]

OC 5GHz
CPU Idle 1.452V
CPU PI 1M~32M 1.392V

Yep .. same Wprime 1024 needs 1.39V to pass 5ghz on air !!!

But your chip can take 5.1ghz 32M

wow 4c8t

and super memory bandwidths..

2300 6-9-6-24 is more impressive

from 100 to 110 but it depends of CPU's ... wait and see with retail one

[PytonOrm]

pretty nice setup dude !!

[irenic]

Great to see 5ghz on aircooling. though I doubt this can be run 24/7.. but IMO why should we bother about 24/7? :p

[yotomeczek]

LGA1155 is quite promising

[namegt]

Good pictures and OC
Nice ~

This is my system.
Waiting for the test.

[i990]

wow 4c8t

and super memory bandwidths..

It's the first time for me to see a memory copy speed which is over 30000MB/s..

OH MY GOD!!!

[i990]

I don't understand why 2133MHz 9-11-9-21 is able to have that much high memory bandwidth...
25000+ 25000+ 31000+ 31nm-

it looks impossible

[i990]

the Logo "wind" is a Chinese character
r u from China? or Taiwan? or Hong Kong?

4.5GHz on air
CPU Idle 1.272V
CPU Full => Hyper PI 8X32M 1.236V

7 second superpi at 5ghz? its not THAT impressive since my 930 can do under 11 at 4ghz.

but it is nice seeing them OC that high, must be BC everything is i the chip. Did you have access to any other motherboards? Like a gigabyte i wanna see how the difference iin motherboard affects it.

BTW nice job man!

that is such a ridiculous and stupid comment to make.
