I don't see why it wouldn't work with 1066's but why use them when 1333 is so cheap( unless you own them)

Even if you buy say 1866mhz and run them at default wouldnt they be @ 1066?
Look like my chip at 5.0GHz can't boot anyways to windows but it can reboot from bios to post screen always and for stable like you too about 4.8GHz and benching 4.9GHz for now on Intel mobo but my chip bclk is bad only 102MHz :(
ps. waiting to try more with other mobo :)
but still is 4.9 GHz verynice for evereday using :)....1.5V and extra 100 MHz is not good idea, your 4.8GHz with lower voltage seems better

Sorry if this was posted earlier
thanks for that spu, good comparison between the 2600k and the 875k
so will 2500K do 5 ghz on H50?
To early for me to speculate, my board/chip makes 48x100 1.35v easy but 49x100 takes a shoot load more vcore just to get into windows. I have googled a lot about this & most appear to be the same, its either the chips can easily run right up to there max & no more or there's another Intel BCLK type bug!!!
.
Interesting with new details, Thanks for sharing and i'll try to check on my chip it same or not with your chip ;)
what about encryption performance of SB?

Thubans are here very impressive!
Beating the 980x by that amount! :eek:

It's Phoronix open test suit(runs under linux).Results are summed up here.
Well it all comes down to encryption used, if you use industry's standard AES encryption , Intel has build in hardware acceleration, nothing even comes close to speed gains, if i am not mistaken all Intel 32nm CPUs will have AES acceleration.
A 2xCore i5-650 with AES beats 12xCore opteron by ~2.48 times, and sandy bridge takes it to a new level.
You could have your OS and all partitions encrypted with AES and you would not even notice performance hit. For a regular Joe it doesn't matter but for those who want it its awesome.

Where can I grab that benchmark?
I have a 2x12 core(6168) AMD MC system, a 2x6 core Westmere(X5680) system and a almost running SB system to test this on.:D
http://phoronix-test-suite.com/?k=home Also runs under windows now i think
or you could get OpenSSL and manually try the bench http://www.madboa.com/geek/openssl/#benchmark-speed
http://www.openssl.org/

In fact, testing RSA is pretty useless. Asymmetric-key algorithms (such as RSA) usually aren't used in performance critical encryption. The main purpose of RSA algorithm is to establish secure connection between server and client and then to exchange a cipher keys. After that any of symmetric-key algorithms (DES, AES e.t.c) are used to exchange actual data.
No amdzone is just a link where one poster summed the actual results(and you know this,you are just using amdzone as an excuse when you are confronted with actual data). You can search for i7 results,they are pretty consistent as long as 64 bit version of linux is used(no matter what distribution).Also the test suite version has to be the same or similar subversion(as 2.00 vs 2.00.b2).Same goes for AMD X4/X6.
Example
(phoronix test suite 2.0.0) :
http://global.phoronix-test-suite.co...807-9811-25231
2 i7s @ 2.67Ghz compared on 2 diff. gnome kernels(x64),GCC 4.4.1 - result :199
(phoronix test suite 2.0.0b2)
http://global.phoronix-test-suite.co...45-12535-29612
1 i7 @ 2.67 on ubuntu 9.04 (x64),GCC 4.3.3 - result : 191.8
Pretty consistent result for i7 at the same clock,the difference is ~3% even though the OS,compiler and the test suite version are not the same(test suit version is the closest match i could get).
If you compile openssl with AES-NI enable, it can yield up to 12x the performance improvment...
http://software.intel.com/en-us/arti...ith-intel-ipp/
So if you want to run openssl and intel just compile it right... the same way goes for amd...
Thats the fun part about open source software.. but they arn't exactly benchmark friendly since you can customize them so much and nothing is standardized.
Noob question: Is 1.5v DDR3 required for "stock" operation? What is the "safe" voltage for DDR3 on sandy bridge (with i7 920 C0 it was 1.65v or so)? I.E. if I'm shopping for RAM, I know "stock" is 1333. Current RAM I have is 3x2GB...
There is newer low voltage ram on the horizon, and I'm wondering if that will be preferred for SB. At the very least, it will run cooler than some of the ram out currently...
Some 1.35v memory is on newegg already... idk if you want lower. ;)
http://www.newegg.com/Product/Produc...e=&srchInDesc=
btw i have used with out problems gkills 2x4gb 1333 and 1600 kits and 2x 2gb 1333 kits. Both on i5/i7 and my 1055t.
Does anyone know what vDimm voltage should be at? Is 1.65v safe or is 1.5v necessary?
If the memory is XMP certified then it will almost certainly be rated to run at 1.65V. I believe Intel does not recommend going above 1.65V on the last 2 Processor generations. It started with the X58 motherboards and has carried on through today. I have seen several XMP modules running on a Series 6 motherboard and those modules requested 1.65V.
Hello,

Noticeable features are :
- Sandy Bridge cores temperature and power meter (HWMonitor)
- Improved clock report (CPU-Z)
- Turbo activation / remove (TMonitor)
- Support for UEFI BIOSes (all)
- AVX accelerated benchmarsk (AIDA64)
You can dwonload the kit at that address :

Thanks :up:
wow nice Franck, thanks for great job :up:
Firstly thanks for this & secondly a few observations..
CPU-Z still reports vcore incorrectly & HWMonitor voltages are out too.
Edit Interestingly TMonitor reports my 2500K in a C state & only when you load the system do you get full core speed.... will have to look into this its all off in BIOS.
.
yeah, on gigabyte P67 boards is the voltage reading wrong.
CPU-Z core voltage is looking at qpi/vtt voltage on my GA-P67A-UD5 dont know if its a bios issue or a CPU-Z issue but thats how it is.
.
Only 5 days left :D

i love sandy bridge really...
this is my aircooled 2600K on a Intel DP67BG mainboard :D

Chri$ch:
Did I tell you today that I hate you!:rofl:
That's higher clock than the clock of i7 920 SP1M WR... Which was done with LN2...
Epic.
omg...Cgrisch...maybe to much vcore-a bit dangerous with aircooling, but still impressive score! How can u run highest Cinebench at air?:)
Jaw dropping clock :shocked::shocked:
I was gonna wait for am3+.... mayne not anymore, wow that's a whole 1.4GHz jump per core from my w/c current 750, dunno who said it here before, but 1156 truly did oc like crappola compared to this
Has anyone tested performance in linux yet?
has anyone determined the max safe voltage for 24/7 use or what kind of voltage is needed for a typical and decent OC?
I dream about 5Ghz++ for daily use!!!
yeap, the process technology used is amazing ... Let's try to wait CES to do a firework of numbers ... ;-)
we got some more good news about OC coming at CES.
Francois
edit
omg I need my UD4 from germany
:ROTF: Bottom line ... The people who predicted the end of OC were wrong again ...
IF you cross Mike Moen, you guys can tell him a big thanks, he spent with the OC task force an incredible amount of time hunting , issues per issues, transistors per transistors every thing that can go in the way of overclocking.
At the end, we get something that will please everybody ...
We would appreciate that even if you are not under NDA, and you got something, that everybody respect the CES 1st day as day to start speaking about it , we worked out A.s off on this, behond anything we did before, give us some credit, and let us have a Magic day the day of launch, that would be good for us.
Play with us ;-) , and let it be a big firework!!!
Francois
:up: Some shops in Germany need their asses busted - they sold CPUs end of 2010 to end users...hope there will be some legal action taken by Intel. NDA and MOA are important to let everybody have the same chance when the sales start - I got really annoyed when I saw them selling the chips.
I am sitting on 8 CPUs but I did not post any screens yet, neither did I sold any of thoose CPUs. I am working for an Intel Premium Partner and have them for own testing and of course reviewing. I could have been a rich man by now if I would have sold the CPUs like those ************** shops in Germany...but no I wanna play with you guys :yepp:
Well unfortunately we already have very good idea whereabouts the OCs will land at due to quite a few guys that isn't under NDA has posted results already, good for aircooling users, not so fun for LN2...
I'd be more interested in hearing Intel's and motherboard makers point of view, why I should still invest in a highend motherboard for a socket 1155 platform despite limited BCLK capabilities? That would be my first question to ask.
dr Whoo: What news about OC? Do u mean Z68 chipset for non K-chips?
What is the highest 2500k can do guys ? about 110 bucks is the difference between 2600k and 2500k, but if the 2500k can go up to 4500Mhz+ , I think its good enough for 220$ ?
Will we need new mounting hardware (backplate, etc) for SB? Does it resuse the same mounting holes as the 1156?
Eastcoasthandle
No, 1156 HSF's fit
Good info, thanks. Perhaps I missed the posts but is there any information regarding temps idle/load, OC?
Edit:
Hmm, found this post so far
still disappointed by the lack of bclk overclocking, you can say bye bye to the times when we bought 40$ chips and clocked the hell out of them (my sister has one of my old E2140s and it runs at 3.4ghz under air (over 100% overclock), my own second rig goes to 3.5ghz with ease)
intel killed low-end overclocking as we know it with this platform and i don't like it...
Our review will be up tomorrow morning. After Intel pulled in their launch (maybe because of the AMD chips launching on the 4th? ;) ) we chose to postpone in order to release content that fit our standards.

Can someone clarify the turbo overclocking? So SB overclocks revert back to the standard multiplier and only activates to the turbo multiplier upon load? So what Asus includes as "C3 and C6 report off" simply turns off the reporting of C3/C6 states so it seems like it's always at full speed but it's not?
