So you mean the UD7 is better in term of more multiplier (higher)?

How do you check max multi on these?

Does it matter where its assembled?

No, its all the same with any P67 board when it comes to cpu multi wall.

4E on UD7 post code reader is the same as AE on MIVE reader

You can also see the VID by starting the computer into windows and using realtemp 3.67 (EIST/speedstep/C3/C6 must be disabled).

For example, in the BIOS, to the left of where you can choose your manual voltage, you will see a VID (might be labeled "Voltage" or just "Target").

If the VID is really 1.15v at 3.4 ghz, then the vcore in health monitoring should be almost 1.13v or lower, and in windows, if you run prime 95, it should be 1.0v or lower.

hmm let me know my vid, which one

http://img339.imageshack.us/img339/3669/defk.jpg

(EIST/speedstep/C3/C6 must be disabled). ----> Done

LLC Auto = 1212 v
LLC Enable = 1.236 v

4.2 GH on 1.224

http://img52.imageshack.us/img52/5306/69423361.jpg

Can you use realtemp 3.67 and check the VID? You can toggle the button on the top right in real temp. Realtemp usually reports accurate VID as long as the CPU is idle and no power saving is enabled. Plus the clocks are there too.

The screen shot has me confused. One has your cpu running at 3.5 ghz while coretemp reports 3.4 ghz. If you're at 3.5 ghz, then the VID will be higher than at 3.4 ghz.

With a CPU as good as yours, your VID should be no higher than 1.24v, and probably lower. However I've seen some cpu's with a low default VID at 3.4 ghz and a high VID at 5 ghz, and some with high VID (1.24+ is considered high) at 3.4 ghz but ironically, lower VID at 5 ghz (like 1.36v VID).

as u wish

so vid 1.251---> BAD ones ?

Thanks, but can you do it at 3.4 ghz?
you're at 3.5 ghz. That's why your VID is so high.

Make sure you don't have turbo enabled in the BIOS, because it will boot you at +1 multiplier if all 4 cores are enabled.

Much better.
Your default VID is 1.2209.
Low VID=usually good clockers.

What vcore do you need for 5 ghz?

5th cpu.. -
5ghz linx stable on 1.336V

more to come.

:down: around 1.45v

What app to use to check for stock VID?

My Fatal1ty board gave the +1 working multiplier to the processor which was capable of 55 multi.
Maximus IV extreme + my 2600K = 5580max, 55 multi (SS)
Deluxe, Pro + my 2600K = 5560 max, 55 multi (SS)
MSI GD65 + my 2600K = ~~5300MHz max, 52 multi (SS)
Asrock Fatality + my 2600K= 5600MHz, 56 multi (Air cooled, Prolimatech Megahalems)

http://img824.imageshack.us/img824/2...litymax.th.jpg

Please don't look at the SPI run time etc. (I was just testing the 56 multi :))

Congrats, nice chip!

You could build a house using all your 2600k retail boxes.

Thanks OC:up:..I can build a small benching shack probly with all those 2600Ks:D

Interesting personal observation from all these 2600Ks are

Most of >54Xs s/n last two digits are in between 80~99

A few cpu came with a square heatsink imprint which indicated that Intel did randomly test its sb chip (and mostly is a dud)

:eek::up:Awesome dude !!! i find good one to booting at X57 but it not booting win 7 on my ssd think its to hot :( batch #L044B676 and this is my 4th cpu

finally dumo!

its not a 5770 but hey 5720 can do :p. same as mine.

how did your 5770 chip die?

Someone on OCN just got a X59 bootable chip (it can actaully prime at X54 with PLL overvolt DISABLED)...

My 2600K is not in the same league as this one of yours but I have to ask...

How do you get GFlops numbers of over 2x that of people like me??? (is it just because you don't run ht?)

Download the new Linpack from Intel Website, and replace the old one in LinX with the new ones recently downloaded... and disable Hyper Threading.

Yours is awesome too:) Love your 285's '01 run:up:

I suspected the old enemy of condensation that killed it, but also my CWT 1300Watter psu was on the brink of dying @ that time. Few times MIVE gave an "overvoltage warning" in bios:(

that's not the VID, I think that's the vcore you're reading.

use realtemp 3.67 and click the toggle at top right while at 3.4 ghz. Double check it there and make sure you have power states/c1e/c3/c6 disabled.

all done - 1.192V
@4.8GHz RealTemp is saying 1.3611v. but requieres 1.43v I guess :?

O_O
That's the lowest VID I've seen (at stock)....
Yet my VID at 5 ghz is 1.3611...(in bios and RT).

Guess at one point RT is stop checking and saying 1.3611 for everything.
Able to boot @56multi with Ait cooling.
Soon will be watercooling thsi machine for quieter use. And will see what's going on.

Still hard to stable it @48Multi and above with air.

RAM is 2x4GB 1.65v so... yepp.
is it bad for the VTT to be 1.051 when the Dv is 1.65. diff >0.45

what anyone ever tried batch L102b281?

Just came back from MC with a new 2500K L101B483 batch and we'll see if this is good or bad. If it's also bad, I'm gonna sell all the SB components and go back to 1366...heheehe...more a joke, but seriously, this SB is probably not for me.

Edit: Just stress-testing a basic OC of CPU Level Up 4.6Ghz on the M4E. Hope it can pass this basic OC. If it does, then I will try a higher speed and see how it goes.

So far it's running very cool! With 4.6Ghz using 1.352v (as shown on CPU-Z), it's showing: 56-57-59-55 with 100% CPU usage (Prime95'ed).

Stay Tuned!

I'm only able to get this to OC to 5Ghz (50x100) at 1.512v (using Offset at +.200) with everything else at Auto. It begins to dawn on me that it may not be any CPUs I've got. Maybe it's my two boards.

2600k bro

I'm glad I decided to try my luck again today at the local Microcenter. L046B028 2600K. 5ghz at 1.408V loaded. 56x multi. 51x multi without pll overvolt.

I dont get a very good OC on my 2500K. I havent done much tweeking but some quick and dirty OC'ing by just wratcheting up everything and setting it to even 45X or more and its not stable. Anyone got any ideas for me because I have followed the OC guides but I still havent seen a good stable OC over about 4.5 Ghz. Maybe its my WS revolution board. Iono.

2500K batch # 3101A127.

Letting Asus utility do a quick OC from the desktop it sets me up at 4.2Ghz and 1.195V. What does this info tell me exactly in terms of OC ability? Anything?

Yep, thats what I based my pick rather than just random. Will try s/n 01~20 next:D

Local MC here have a bunch of old stock L046s and 51s, costarica batch still in the stock room:)

Its a keeper Baba, have fun with it:up:

2x 2600K's incoming with in 48-72hrs.. will be paired with a UD4-B3, is 4.5Ghz a guaranteed minimum OC?

Many thanks... that sorted it.

I wonder how many others like me get the not so good batches? this one needs almost 1.55v for 5.0 :(

Demo: For all that mine is poor, it went to 4.5 on auto everything (same board)

anyone know how to find MAX multi on 26K or 25K ?
Fastest way plz

With low air / stock cooler, disable PLL overvoltage, 1.45v , 2cores, HT off ( 2600k ) . Start with 50x, and walk your way down.

Your max multi will more likly be [multi without PLL ov ] + 5. So if you can do 50x without PLL ov you 55x will be your max multi.

I have a silverstone zues 750zf (3yrs old)and silverstone strider gold 80 750watts (brand new) on my end and will be initially testing the OCing on the strider 80, in this case would the PSU matter in overclocking or its not really a concern ?

thx, mine without PLL ov = 47x
with PLL = 53x :down: ones

Think I'm done with SB. Gonna go back to 1366 and wait for Ivy Bridge. No more binning SB CPUs.

Did you at least try swapping the board first?

Need little more tweaking to get those settings 32M stable.. after 16 rounds superpi gave error.. :(
And mobo wont take bus more than 104,8, cpu is also near it's limits with aircooling.. I will give it another try with m4e which should arrive at friday!:up:

Ok for those lower ones you might get + 6 multi's. But after going around 50x without pll ov, ~+5 is what I've been seeing so far.

If you wanna risk it. 55x PLL ov on 1.5v 2 cores, windows = winner , no windows = sucker :down:

A Mhz wall is what any SB chip born with.

Once found, then we can try to find another wall for vantage cpu 4C/8t

I have the Deluxe and Maximus to swap CPUs around, all CPUs that came through me pretty much did the same. There is no reason to doubt two top end mobos anymore. Also, I've sold another MIVE to Dumo and he is doing great with his CPUs, which I wasn't able to when it was with me, so actually three high end mobos.

I've noticed/followed your posts in this thread over the last few months and you did seem to have some poor luck :( with your chip samples. What was the max multi on your best sample?

I binned a few SB my self... but not nearly as many as Dumo ;) and I had my share of average and below average chips along with a couple of decent ones when I finally decided to take a break from binning several weeks back.

I had originally wanted to find a strong low voltage 2600K... 48x stress stable with 1.3v or less and ideally 57x(+) multi but I never did find one.

I am not blessed by the hardware Gods either.
My 2600K needs 1,24 under load for 4300MHZ which is "OKAY" judging by your results but needs 1,33 for 4500 and 4700 is not stable at all with 1,376V which I consider barely within safe limits for everyday use :shrug:
I simply never get nice OCers :rolleyes:
My P4s were trash, one would not even run Prime reliably at stock, all my TBreds as well, my E8400 was okay but degraded even without Volts, my Q6600 probably was the worst OCer on earth and my Q9650 was at least not bad. Same goes for graphics cards :p:
The Barton I own which did nearly 3GHZ on air was not bought by myself so that does say a lot for future purchases :ROTF:

got mine at microcenter

So far pretty consistent even with small random samples...

SS cooling / UD7 B3 / Bios 1.54Vcore LLC10

3101A201s MHz wall 4C/4T

# 0329: 5450 MHz
# 1181: 5500 MHz
# 1499: 5650 MHz
# 1531: 5470 MHz
# 1983: 5750 MHz
# 2242: 5470 MHz
# 2247: 5350 MHz
# 3365: 5550 MHz
# 1418: 5350 Mhz
# 2011: 5523 Mhz

@Dumo, The SS cooling does not seem to be extracting major O/c's. Can you confirm this? Or are these clocks good because the chips were low multies to start with?:confused::)

Have you tested IBT AVX with those 5GHz settings? About the same acting chip like my.:up: 56x possible?

yea but it's a Super Pi run not so interesting, and does not say much on whether it is a good CPU.
for me Prime must see to run at least 1,5h to grant around it is a good CPU.
Super Pi simply no optimization

These cpus Mhz. achieved mostly by the second or third boot with BCLK on easy tune and after 53X initial boot passed to windows.

The "major" chip imo. is the one that can passed 5799Mhz wall with all cores or even with 2 cores and it is still rare:)
Even after found it, most likely it will be good @ that Mhz for certain benching. Vantage and '11 will be benchable depend on how good the imc of cpu

What I can say is some batch of 2600K over all is better than the other.

Highest I have been able to do on water, dropped multi to 54x. A201 chip, costarica. Boot from bios, Will try et6 and see if it will do 5.7.

Do do you loop Vantage and 11 CPU test for X numbers of times?

No loops. If it can finished both benches then most likely it will good to go @ that Mhz and settings.
Stability is not the goal, finished bench is.

Again, a "good" SB cpu is depend on how peeps look at it. A 5Ghz with 1.37Vcore on air cooling and passed prime 97 for 7 days non stop probly consider good, then there also a 2600K that can finished 3D '03 at 5.9Ghz 2 cores with 1.7Vcore on LN2 all day:)

One thing for sure that every single SB cpu have their maximum Mhz wall like a fingerprint

So what batches are better B or C at the moment? Planning on a trip to MC soon. ;)

Supposedly C batch is better (in general) but they are not available in the US, I believe.

i got a 3101A113 commin soon if it does 58x i'll trade ya for a 1.37 5.0 cpu

I got two 'c' batch at frys a few months ago.
L040C106 it's ok, does 5.0 at 1.42 loaded. PLL overvolt off

I JUST put in a

L040B208 and it does 5.1 1.38 loaded PLL overvolt ON.

EDIT: Also tried a L039B214 and it was a dog. needed upwards of 1.5V for 5.0
All above 2600k's BTW

@noobzed

Looking good, hopefully I'll be able to pull those numbers in a few weeks!

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."

Can anyone expound this idea further, since I will be getting 2x 2600K's and I need to know which one to keep in 2-3 days time only.

And whats the max voltages for VccSA/Vcore/VTT and vDIMM you guys can recommend for 24/7 usage under air cooling. Will be cooled by a Noctua D14.

From what I've been able to gather, Vcore = 1.400 , QPI/VTT = 1.1 , vDIMM 1.72 , VccSA = 0.971

3102C318 *A3160 5,5Ghz....so far

I would trade my 1.37v 5Ghz CPU for a 58x LN2 benching any time of the day :up:

I just got my parts and both 2600K have the batch# L108A948 any input on this?

test it :).

no batch is good for certain. you can have 5.2ghz and 6ghz in the same batch.

same batch but # 1369 but a hazzle to know if it will be good but for your experience i can guess it can do 5300 min

Installed one just now and realtemp 3.67 shows 1.2710 stock VID.. pretty high??

I'll try the other one tom..

EDIT:

Updated my bios to F4, bios VID shows 1.260.. windows realtemp 3.67 shows 1.250

It is a good batch. Good luck:up:

dumo u tested till what multi they boot with no internall PLL ? and 5ghz stable ? on them HT ?

i ask you this because its for a friend willing to do 5gh stable HT with it as my batch does

cheers and thanks
