Sandy Bridge 2500K/2600K Batch and Serial Numbers

[Massman]

How to bin

Binning Sandy Bridge is extremely easy.

- use HS fan with easy mounting
- set Vcore to 1.55V
- disable EIST, C1E and C-States
- disable HT and 2 cores (to not make it overheat with crappy HSF)
- increase multiplier

You just need to see the windows OS options, not actually boot into windows. If your CPU can show the different OS options, stability will just be function of Vcore and temperature. If it doesn't show the OS options, you will never get it stable anyways, so you might as well ditch the CPU.

Usually, it takes about 5 minutes to see if the CPU is good or not.

With some CPUs, you do have the issue that some multiplier is better than the other for stability. For instance, my current CPU can boot at 51x MAX (~ 5145MHz). When trying to run near this max speed, I have to use 49x instead of 50x multiplier because it's a lot more stable.

But, that's something you don't need to test. With BCLK adjustments, you'll never get 5200MHz going or so. Multiplier binning is the best way.

I was invited to day by the Belgian high-end PC shop TONES (http://www.tones.be) to play with Sandy Bridge at the Intel launch party. Together with other [M]-boys (Leeghoofd, Pt1t, Gamer, Teemto and Piotke) we tested 5 retail chips. Here's what we found out:

Batch: L039B470

# 0028: 4900 MHz (http://hwbot.org/community/submission/2102991_leeghoofd_unigine_heaven___xtreme_preset_d x11_geforce_gtx_570_1450.58_dx11_marks)
# 0030: 5200 MHz
# 0298: 5250 MHz
# 4672: 5415 MHz (http://hwbot.org/community/submission/2102510_pt1t_pifast_core_i7_2600k_13.58_sec)(air)
# 4673: 5375 MHz

Those CPUs had two different types of S/N. The 467x start with 2V036, the others start with 35038.

I also tested one 2500K ES:

Batch: L035B183

# 1377: 5200 MHz

And one 2600K ES:

Batch: L035B191

# 0771: 5288 MHz (http://hwbot.org/community/submission/2100246_massman_superpi_32m_core_i7_2600k_6min_22s ec_125ms)

i got a 2600K - L039B470 - #0220 (sn:2v036...) 5200mhz (spi stable / 3d not tested yet) on cold water 1,55v(bios)/1,53v(real).

[Massman]

For your information, you can also see the # of the CPU if you look at the sticker on the box. The last 4 digits of the S/N are the same as the ones on the black sticker on your CPU.

[TiN]

What's the point? :)

[Massman]

Fueling the hope that random numbers will enlighten us on the overclocking capabilities. Also, providing justification for spending money on yet-another CPU by the 'it should be good'-argument.

[1Day]

I guess it is like stamp collection I never saw the point of that but many people love it = and like stamp collecting it does no harm. :)

Here is mine L040B307
#2458 5.288 GHz

[AnotherCanuck]

Registered just to say I have an i7-2600K...

Batch: L038A659
#: 2083

I'm quite certain it's a dud. It runs incredibly warm (Stock settings: It idles at ~42C while Speedstepped down to 1.6Ghz @ 1v and tops out at 75C under load when turbo'd to 3.5Ghz) and I cannot get it to OC past 4500Mhz. If I set the Vcore any higher than 1.37v the system fails to boot.

I'm using an Asus P8P67 PRO with the latest 1053 BIOS with the PLL Overvoltage fix (enabled).

I'm heading back to the store today to exchange it hopefully.

[Massman]

Okay, added :)

# was 1915.
CPU is dead now. Funny thing is, that it was able to run two days in high oc mode, but yesterday I put air cooling on it, set ratio 40X, all voltages was default, run OCCT and left running.
At morning I see BSOD on screen, restarted, run OCCT again- BSOD almost instantly. Load defaults in bios, restart, but can't load windows, tried with other HDD- same story- sometimes it boot in win, but not stable at all.
So seems, that SB is fragile as its other 32nm brothers..:(

[Dancop]

Is it possible to say, a lower number might be a better chip?

[Massman]

No, definitly not. So far, there isn't really that much to conclude based on the numbers. I would currently advise to search for CPUs as close to the golden ones. For instance, if a golden CPU is L043A776 #3986, you want to search for the same batch (L043A776) and a # close to 3986.

[Dancop]

I had a L040b307...some can boot 5600, mine was poor!
then I had a L040B690...that was the worst so far. Now I own 2 L042B076 #0207 (runs 4,5 @ 1,24V) and #0083 (to be tested tonight!)

but if you want to spot a trend between "numbers" and overclockability (if there is some, of course) you should be looking at the highlighted numbers (http://h-4.abload.de/img/dsc049284ris.jpg) from the ATPO, at least with cedarmills they tell a lot more than the last 4 digits you're asking people here...
from what I found locally, "043" means the actual date of silicon production (for example E8600 with "823" are good no matter the batch)

2500K - L051A872-2452 (http://h-2.abload.de/img/dsc04929rx2d.jpg) - could POST 100x56 on air with an ASRock P67 Pro3

but if you want to spot a trend between "numbers" and overclockability (if there is some, of course) you should be looking at the highlighted numbers (http://h-4.abload.de/img/dsc049284ris.jpg) from the ATPO, at least with cedarmills they tell a lot more than the last 4 digits you're asking people here...
from what I found locally, "043" means the actual date of silicon production (for example E8600 with "823" are good no matter the batch)

sam is that post bios or boot windows?

[Sam OCX]

only get to see the POST screen and get to the OS selection menu .. couldn't test up to the OS because the OS has been previously corrupted with unstable memory (BSOD during driver install)

nice numbers. don't know if anyone has posted this batch # L042B208 right now @ 5ghz solid and moving up till i hit a wall. using UD5 F6d bios on air. i did have up to 5.3ghz on Sabertooth and it was steady dont know about solid....:)

Got a L050A853 from microcenter yesterday.
Currently working on a 580 so no time for it yet.
Anyone else have a L050 yet?

Hey, can you update me how well yours OC? I saw this same batch at my local MC and if yours OC past the 50x100 (5Ghz) with lower than 1.45v than I'm going to get it. If not, and if it needs 1.50V+ to run at 5Ghz, then I will pass. Please let me know. Thanks a bunch!

I have that batch as well and so far it needs 1.50v+ to run at 50x100 (5Ghz) stable. Anything less then 1.50v results in BSOD. To me, 1.50v for 5Ghz is simply too high.

Are you guys booting at max freq. on the Asus boards with your 5ghz+ chips or changing in OS with something?
I've been booting max freq.

Reporting two new chips tested on air:

Wasn't stable and doesn't work with more volts or less volts. 51x, 52x, and 53x nope. :(
Booted at 4c8t and 4c4t no difference both unstable.

Binning Sandy Bridge is extremely easy.

- use HS fan with easy mounting
- set Vcore to 1.55V
- disable HT and 2 cores (to not make it overheat with crappy HSF)
- increase multiplier

You just need to see the windows OS options, not actually boot into windows. If your CPU can show the different OS options, stability will just be function of Vcore and temperature. If it doesn't show the OS options, you will never get it stable anyways, so you might as well ditch the CPU.

Usually, it takes about 5 minutes to see if the CPU is good or not.

With some CPUs, you do have the issue that some multiplier is better than the other for stability. For instance, my current CPU can boot at 51x MAX (~ 5145MHz). When trying to run near this max speed, I have to use 49x instead of 50x multiplier because it's a lot more stable.

But, that's something you don't need to test. With BCLK adjustments, you'll never get 5200MHz going or so. Multiplier binning is the best way.

[Splave]

Gotcha. That doesn't apply to the Asus boards when you OC with turbo multi though does it? For example most of my chips can get to the windows load screen at 55x+ turbo multi but they can't actually get past the windows loading page into the desktop. Testing on SS now and tested high volts, doesn't help me get higher and none of these chips is going to actually finish booting 55x+.

thanks for this hint.
im sure many people try to boot the chip, which is difficult due to bad heatspreader and the so caused high temperature raise during boot.

3DMark06 @ 5418 (http://hwbot.org/community/submission/2113624_)

It also ran 01 (http://hwbot.org/community/submission/2112235_) & 03 (http://hwbot.org/community/submission/2113623_) there. 01 result was disappointing of course because Gigabyte seems to have the market on those results.

Vcore for all of that was around 1.6'ish loaded. It was 1.584 idle but LLC was on full, so it boosted a hair under load. Cooling was this classy looking water loop (board & RAM changed for the results above):

914

That was one evening of benching. Couldn't get it to boot at 56x. Yet. Rest assured I'll try when time allows. Haven't even tried BCLK adjustments yet. Lots of toying around to be had, but this should be enough for another batch data point. :)

Gotcha. That doesn't apply to the Asus boards when you OC with turbo multi though does it? For example most of my chips can get to the windows load screen at 55x+ turbo multi but they can't actually get past the windows loading page into the desktop. Testing on SS now and tested high volts, doesn't help me get higher and none of these chips is going to actually finish booting 55x+.

this is a quite interesting information - thanks for sharing :)

edit: so finding the maximum multiplier seems to be more easy on gigabyte boards?

[chew*]

this is a quite interesting information - thanks for sharing :)

edit: so finding the maximum multiplier seems to be more easy on gigabyte boards?

yes but i might add, I'm on cold water and even though you can post a multi doesn't mean its stable.

L050A933 chips seem to need excessive amounts of voltage. I would avoid that batch alltogehter, even if you did find a 55X chip i doubt it could be tamed on anything but ln2.

8c water can't even get a wprime 1024m off at 5.4.......they seem to be decent enough low leakage chips though, 1.30 for 4.5 prime stable.

[chew*]

Hey massman.

Lets start requesting default VID of batches along with the other info :) just becasue a chip has a decent multi doesn't make it good.

Also have a hunch that within certain batches multi is tied into VID somehow ;)

2600K L050A933 2210 54 X not 5.4 wprime 1024 stable.

2600K L042B208 4508 51X didn't waste my time.

The first letter or digit , shows us , in which Intel plant the cpu was made.

L=Malay

3=Costa Rica

0=2010
44=week of that year


It's the first SB cpu i've seen from Costa Rica plant.

[Dancop]

No Valids so far....but sure in my opinion!
L051A975 #???? = 52x Multi
L072B074 #1038 = 52x Multi

Poor ones!

http://hwbot.org/community/submission/2127716_dancop_pifast_core_i7_2600k_12.88_sec
L042B076 #0799 = 58x Multi but max clock was 5731

[SniperOZ]

New CPU not what I was hoping for :(

Core i7 2600K
# 3264: 5390 MHz
Batch: # L047A898

[|ron]

Tried another CPU, just a fast run to see how it was.

- L101B381 SN: 0184 / Giga UD4, 32M stable, HT on @ 5,6ghz.

Didn't try to max out the frequencies, maybe something more is possible, having more time to try :)

somtimes it's able to boot with x55, but totaly random and not stable.

[SoF]

Not sure if I ever told you the digits so here is a little update:

2600K

L040B165 #0916 - max 2D and 3D 5589, booting 5597 but only 1m and very unstable

today I got a new one and just had a quick look on it before popping it in.

L038B638 #28XX (61 iirc) - ~5670
that is one nice chip, does 5665 easy and boots 5680+...seems I still need to find optimum voltage as 2nd run was directly 5665 which also ist my limit for most of the benches until now. 32m just passed with 5min 56s flat YAY :)

Tested another one, same batch L101B381, a total disaster.
This one SN is 0891, it can do max 52x multi, so 5.240mhz max, by adjusting a little the bclk.
I can't still view a correlation between a good cpu and batch/sn :(

[MAGARAC]

5240 is no so big disaster. Tested 3 so far and the best one is x53 other two where x51. Right now I would be very happy with good x54 cpu.

[|ron]

a 5240mhz cpu is worthless, since we had a 975 that could do around 5,3ghz in 3d benches :)
Anyway, the cpu I reported a few days ago is finally in my hands, my friend decided to exchange it with mine since he doesn't overclock, so it's pointless if what's in his case can do 5,3 or 5,6ghz :)

[Linuxfan]

a 5240mhz cpu is worthless, since we had a 975 that could do around 5,3ghz in 3d benches :)

Gotta disagree with you here. For one thing, you don't use LN2 with the SB CPU so less money and hassle.
Also, a 5.2ghz SB is MUCH faster than a 5.3ghz Bloomfield. Much more efficient in most 2D and 3D. Not faster clock for clock in Wprime and Vantage, but '01-'06 and Pifast and Spi its much faster. Will blow the i7 975 away. ;)

[|ron]

Yes, I use LN2 on SB, I simply don't go below -40°c :)
Anyway, ok, 5,2ghz SB is faster than 5,3ghz bloomfield, but if I must pay 500 euros (cpu+mobo) to "migrate" to another architecture, I want a good improvement... 500euros to have performances up by a 10/15% factor is not worthy.
So we sold our previous 2600K and now we found that one, which is stable @ about 5.6ghz and THAT is something better in comparison with a bloomfield :)

So does intel cherry pick retail chips for benchers?

This chip straight from intel marketing.

L051B170 0586 53X, didn't waste time testing further other than to jump multis just in case.....

Oh and to put a # to my 5664mhz L041C108 4323

Also we forgot to add all the junk from L041C108, forget the numbers but the count is 10 chips 53X to 54X

so does someone have a super computer we can punch all these numbers into to find out if batch means anything? Maybe the 4th number of the serial number plus 5 x .873 equals a prime number its a good chip?

A little L041C108 party reporting in...
All done on water with a M4E

#1333 booted 100.9 5449mhz 1.55v 2c2t absolute max
#3576 54x took more than 1.55v to boot 2c2t. Booted with 1.62v
#3984 54x 1.55v boot
#4584 52x boot 1.55v

So out of 4 chips... 1 is 52xx and three are all 54xx with one that doesn't run with lower voltages.

so does someone have a super computer we can punch all these numbers into to find out if batch means anything? Maybe the 4th number of the serial number plus 5 x .873 equals a prime number its a good chip?



We had several theories while binning, though mostly the next CPU obliterated it again :p

Thx tones for the opportunity !!

Updated opening post. Counter:

DInos: with what setings it was done? 1.55V and max validation? Or...Thx.

[dinos22]

i just quoted massman i didnt do any testing

[Leeghoofd]

We did it like this :

1.55Vcore set, try to boot 54X. No boot or no HD detected : drop multi till we got into windows ... If boot was succesfull at 55X, try higher... mess with bclock...

Takes about 5 mins per CPU...

i don't SELL ANY OF THESE CPUS ..but your have taken the best 3 for your self I guess

[Massman]

Yes, of course. I didn't take a day off to just test cpus and go home again :p

[Predator]

Massman, you're not selling them? ok if you're giving them away i want the 5730 one :D xDD j/k :p

[mac87]

to be clear on looking at the # number of chips
I made this quick graph
no significative tendancy can be observed between #number and the maximum oc
even for close #numbers, the difference of max oc can be huge

mean oc is 5300MHz

http://img200.imageshack.us/img200/6347/sanstitrefp.png

[Massman]

The issue is that we don't know how # are assigned to the CPUs. So #10 might not be 5 places further away from #15 than #20.

yes of course
it depends on the sketch used for numbering

[AlbertMwugabi]

Core i7 2600K
# #2475: 4500 MHz, not maxed
Batch: # L040B690

:)

Gonna buy a new chip soon, any batch i should ask for?

[sno.lcn]

L045B021:
#1771: 5100MHz

L051B138:
#1292: 5500MHz
#2128: 5500MHz

[knopflerbruce]

L040B165:
#1021: 5600MHz

Edit: I'm a rookie though... could be user error that it wont go higher :p

[QuantumX]

Batch: L040B313T #2620 - 5317.5MHz

I left all the settings in the BIOS on auto (volatages included).

Asus P8P67 Evo

Ran SuperPi 1M without issues. I think I can get to 5500MHz if I start tweaking with the voltages. . .

By the way, why does this batch number have a "T" at the end, or do all batch numbers have that? (I got the number from my CPU box)

[Massman]

Hey guys. Stop going to the shop and present yourself as 'Madshrimps'-member just to get your hands on those chips. Even if it's urgent to participate in the MOA Benelux qualifiers ...

//EDIT: Just confirmed the shop that no permission has been given to ANY Madshrimps member to go and ask for a CPU.

[Mean Machine]

PR gone wrong then. :D

Lemme be topical and helpful for once though:

L046B509:
4294: 5540MHz
0198: 5460MHz 2c/2t
0028: 4900MHz

SuperPI 32M stable frequencies.

[Leeghoofd]

Jonas = epic fail :p

[Mean Machine]

Jonas = epic fail :p

Still won, which means I shouldn't have bothered. :)

Updated list.

(although I really didn't want to, also added Mean Machine's chips)

massman's method for highest multi isn't working on p8p67 pro or? because with mine i also see the "starting windows" screen with multi 60 but i only be able to boot without changes of different settings with x53 onto windows. only put 1,55 vcore and disable HT and 2Cores.

[Massman]

Disable EIST or C1E :)

thx massman. i think i have reached the end with x53. bclk ist also the max with 100,5 on a p8ö67 pro B3. stepping is coming tomorrow when i switch to SS.
btw was a L040B166 and 53x max on air.

just got a 2500K and before I forget to look on the numbers here is the data of the chip, will update results later.

2500K 3101A030 #1588

€: well it wasn't the worst chip but got damn hot with 1.6V and could hardly do 5400 on air - 5500 gave instant freeze so it goes into my gf's new sys ;)

Sure you didn't forget to turn PLL overvoltage on or something?

Slightly above average :) Enjoy

Why all my cpus on AIR overclock more then on SS....10-60mhz more on air....anybody know the secret? mobo ud4. post "4E" or "CE" with same settings when go to SS...

[Bullet1]

Tried lower voltages? What about temps?
