This article is also posted in my blog: WIND'S 3C
Welcome 3C fans to drop by.

Thanks :)

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

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

Very nice.

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

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

wow 4c8t

and super memory bandwidths..

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 :)

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 :)

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.

@ Toolius

yes is possible ;)

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. :p:

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

But your chip can take 5.1ghz 32M :D

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

pretty nice setup dude !!

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

LGA1155 is quite promising :)

Good pictures and OC
Nice ~:)

This is my system.:D
Waiting for the test.

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

OH MY GOD!!!

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

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!

:rolleyes:
that is such a ridiculous and stupid comment to make.

11.000 * 4000 = your efficiency 44,000
7.551 * 5000 = his efficiency 37755

That means at your 4GHz he'd get 9.439s, and at his 5GHz you'd get 8.800s - a 17% difference clock for clock!

i would buy 2500K / 2600K !!!!!

7.55s 1m is very fast for 5ghz. My 920 at 4.9+ghz scores 8.233. He is on air, compared to other cpu's running around the same times he is very fast, most are well above 6000mhz to get the same score.

cannot agree more!

he has no idea about the difference

Weird to see two 8-pin EPS12V connectors on such a simplistic board. :lol:

5.0ghz @ 1.45 vCC? :D sounds like the old C2D (E8600) ... the LGA 1155 seems to be really interesting ...

Yeah, my first reaction was about the simplicity of the beard, but the whole NB-thing (and the cooler) is gone bye bye, and that's why it looks simple.

That thing is not simple, good stuff is on the way :D

That screenshot you took is of 7.05- 7.06 second runs not 7.55

Just so you know...


Looks to be good efficiency though, better than X58, although not insanely much.

TBH this looks more like a die shrink, with limitations. Will see if manufacturers get around this limitation somehow as they did with the ones on the X58 platform.
Definitely looking forward to more results.

Sry my bad.

Windwithme, Nice Bench! looking forward to see more :)

Man I want one of those and a UD7...
I already see 5.5ghz watercooled, pair up with a couple of graphics :D

Damn you are a visionary :D

风大的帖子总是很厉害！Will dual core sandy be even better for oc? It's sad if they'd not offer unlocked multipliers for any dual core sandy.

+1 on the new UD7, the new look is a awesome.

数据分析帝你又来了！

World records incoming!!.

please give us some 3DMark runs to compare :)

5GHz benchable @ <1.5 with ΗΤ @ air is promising - can't wait for the dual cores :shocked:

wow look at those insane write/copy/latencys!! impressive as hell! Cant wait for there high end in 2011.. their 1155 already owning up the current competition..

Yes, it can achieve to 5.1ghz 32M:)

This is amazing, waiting for more

It's Chinese for Wind ;)

Or are you addressing him?

Interesting thread. Thanks for the post WWM. Looking forward to more info (Sub'd).

windwithme, may i make a request of a 3dmark06 cpu test? :)

SB looks great. What are the temps? 24/7 voltage range for SB? I wish they just left the igpu for lower end parts and mobile parts.

Very nice.
Really interesting

Aww can't believe I've missed this thread (gotta try check Intel section more often compared to News section :rofl:), I've been dying to see some proper OC results with full info shared. THANK YOU SO MUCH!

Quite impressive Everest (AIDA) memory benchmark numbers, at the stock setting 3.5GHz DDR3-2133 9-10-9-27 you get almost identical results as to my P55 setup at 4.1GHz DDR3-2340 9-10-9-24 !!! :eek:

I wonder how safe it would be to run SB 24/7 at such voltages though, that's whereabouts people usually draw the line for their current 45nm Lynnfield setups as far as voltages go for a 24/7 setting (on air), still at least 4.8GHz or so could be done probably at 1.35v or so perhaps and that'd still be a nice result. But so far it seems nearly all SB 2600K reach 5GHz at quite similar voltages ~1.4v so that's a good sign of that the manufacturing process is doing well for SB.

ok yea its 1 second faster. I guess its a good improvment i really didn't think about it. 920s at 5ghz do 8 second super pi. Aren't 1156 i7 800 series faster than i7 900 series clock for clock? so wouldn't this be kinda on par with that? IDK i kinda expected somthing a lot faster i guess that would be 2011, even though it seems to be the same architecture as 1156, i was expecting more from oups cache, but his memory bandwidth is very nice. Anyawys nice job.

windwithme, could you possibly test OC with HT disabled to see how much of a difference it makes, how much vcore you need for 5GHz then, for example, thanks. AFAIK no1 has provided such comparision yet...

BTW your last picture of the RAM sticks are a bit unsharp.... sorry I'm just teasing with you, your pictures are always so nice and sharp. :p: BTW how are you associated with BioStar? Last time when P55 was released I remember your early oc results of a i7-860 @ 4.2 ~ 4.3GHz at similar voltages on a biostar mobo then as well.

Here's My 32M at 4.6GHz on "Air" :) http://i1004.photobucket.com/albums/...king/8m110.png

Found this in Germany:
5.1GHz i7-2600K, watercooled.

nice benchmarks, Cinebenchs are cool.

Does anyone know if the mounting holes on the 1155 boards are in the same place as the 1156 motherboards?.. I see the Prolimatech hsf used but i can't tell if he had to mod it to fit

yes, the mounting holes are the same as on the 1156 mainboards.

5Ghz on air,Cant wait to see what i can get with Phase.

What is MAX Multi for 2600K

I think its 48.. Really depends on the chips though

lol so where are the w/c oc screenies? or will I have to post my 1156 water setup to see some results

This is getting interesting. Looks like some new records might be on the way.:D

For some of us here, there is still a NDA to be followed...

Man i am jealous of you having those pretty hardware to play with. getting a golden sample of a cpu is so nice!

Looking at this I like SB a lot, though for me and other benchers it's gonna be a bummer if I can't go subzero soon !! (need a new LN2 deal somewhere somehow...)

QFT leeghoofd;)

Recently i looked at my Singlestage and it seems bored:censored:

No dualcore 'K'-model i scheduled, so all dualcore models will not be overclockable

wow thats the nicest looking biostar board ive ever seen! :toast:
i really like how they went black pcb but red and WHITE instead of red and black like EVERYBODY these days... very nice! :toast:
and the components look good, the top pwm heatsink looks very nice... clean layout... nice...
only the left pwm and the sb heatsinks look blocked by that stupid metal caps with a branding message on it... but i have high hopes those can be popped off...

if this goes for around 150$ and has a decent bios its going to be a very nice board i think...
