Massman Posted November 15, 2011 Posted November 15, 2011 How to bin It seems that the SB-E has the exact same OC characteristics like the regular Sandy Bridge, including the infamous clock wall. It's not as easy to find the clock wall as with Sandy Bridge, but here's a guide that will be able to give you information on your sample's maximum overclock. Under discussion again ... FYI, I found there is a way to bin the CPU on air. I tested it with this CPU and it worked like I expected. What you need to do: - go in bios and set all VRM config like you'd do for extreme OC - run 2c2t (to save heat) - set vcore to 1.55~1.6V - set bclk to 100 Now, increase the CPU ratio. In the beginning, you will be able to boot straight in to OS. After a while, it will crash at OS loading (for W7, it will lock at the ball swinging moment), but when pressing the reset button, the board will reboot. This means it can run this frequency with better temps! Once you lock and pressing reset doesn't work, you've found the maximum frequency of your CPU. In my case, I could always reset from lock-up upto 55x. With 56x, I could not reset and had to power off the entire setup. The end result was 5510MHz for my CPU under LN2.

Splave Posted November 15, 2011 Posted November 15, 2011 Testing two 3133b684's a1455 is one I will get SN end of other in a bit Quote

Splave Posted November 16, 2011 Posted November 16, 2011 3133b684's a1455 5ghz wprime 1024 @ 1.425v Max vantage CPU test 5371mhz at 1.65v Chips are very similar except first one can boot 5418mhz other one will only boot 5388mhz perhaps batches are similar again. Quote
Massman Posted November 20, 2011 Author Posted November 20, 2011 Anyone found a good way to quickly bin these chips? It seems that the SB K-sku routine is no longer applicable (at least no on this board) as the turbo multplier only kicks in when actually entering the operating system and no longer when the boot options are being shown. So, no blinking cursor anymore. Also, it seems that the chips really need colder temperatures to show the max CPU OC capability ~ 0°C. With low temperatures binning should be relatively easy (NickShih mentioned 1 per 5 minutes), but not on air anymore. Quote
matose Posted November 20, 2011 Posted November 20, 2011 Binning on air is useless, -10 to -20 should be a good binning temperature at around 1.6v just to be sure Quote
Splave Posted November 22, 2011 Posted November 22, 2011 ^ totally agree 2 more but this time 3930k's from newegg 3133B431's will test this afternoon Quote

Eldonko Posted December 2, 2011 Posted December 2, 2011 Picked up a 3930K today, 3133B432 #1388. Hoping for 5.5 at least! Quote
Massman Posted December 2, 2011 Author Posted December 2, 2011 Let's also note down max memory clocks ... should be interesting. Just tested my first retail 3960X: no 5200 cpu, no 2400 memory. Popped in the 3930k, easy ddr3-2400 first boot. :-/ Quote
Khalam Posted December 2, 2011 Posted December 2, 2011 got my first 3930k yesterday, 3133B431... worst sb ive ever heard off.... 4.8 at 1.55 and not an mhz more even at 1.675:( Quote
Massman Posted December 2, 2011 Author Posted December 2, 2011 What board and what temperature? Quote
Hiwa Posted December 3, 2011 Posted December 3, 2011 3133B483 2570 memory Wn: 0737 2520 memory WN: 0748 Quote
Khalam Posted December 4, 2011 Posted December 4, 2011 its an MSI GD65 8D (thanks to your thread about the board ive managed to get it to 5ghz a few minutes ago:) temp wise im getting 22-25 idle and 63-69 load. I have to figure out how to mount my ss on this board so I can try what will this chip do under sub zero.... still a terrible chip that requires 1.625v for 5 ghz.... Quote
Lower Posted December 4, 2011 Posted December 4, 2011 3134B362 (3930K) Boot 5401 / Vantage 5375 - IMC not testet. 5375 @ 1,55V Bios - 1.56 @ Readpoints on RIVE Quote
Massman Posted December 5, 2011 Author Posted December 5, 2011 Added some of the infos to the opening post. Quote

With that little trick, it should be running "normal" voltage range. Quote
Massman Posted December 6, 2011 Author Posted December 6, 2011 Testing another 60X chip. First one didn't even do DDR3-2400; this one is at least booting at DDR3-2400 . Quote
Earthdog Posted December 7, 2011 Posted December 7, 2011 Not sure if you want ambient testing as it seems one is unable to test these to the limit with mere ambient temps. But here is mine. The other will come soon after... 3133B433 - 4.94GHz / ? / ? @ 1.48v (from DMM) ambient water ONLY. Quote
OBR Posted December 8, 2011 Posted December 8, 2011 Only ES i have ... finally had some time to bench, it seems good ... Rampage IV Extreme, -15C Max mems - 2450 MHz (old 2333 Kingstons) at 1.67V on air Quote
