i5-2500K/2600K batch number and o/c results

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

@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?

[angkies]

thats an awesome cpu angkies!

im soo lucky bro

i7 2600K L042A969 # 0465



5ghz 1.385v bios, Internal PLL : DISABLE !




5.5ghz 1.58v bios

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

[Ace.]

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.

[OC Nub]

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.

[Demo]

Vantage and '11 will be benchable depend on how good the imc of cpu

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

[Dumo]

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

[Lu(ky]

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!

"Thanks for the input guys!



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

[st0ned]

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

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

[Demo]

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

[Demo]

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

[Dumo]

It is a good batch. Good luck

[andressergio]

It is a good batch. Good luck

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
