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

[flesheatinvirus]

I use mostly Gskill with great success though others like Corsair. I just got in another set of F3-18400CL9D-8GBXMD to test but so far my best results have been with there F3-17000CL7D-4GBXHD.

[aussie-revhead]

In general are the newer batches getting better or worse? Or still just as random as ever?

[AliG]

I would say getting better, my 2500k is windows 24/7 stable at 4.5ghz with stock voltage. However I haven't tried anything too demanding yet, no games/benchmarks just casual use so far

[badatgames18]

I have gotten two x55 and a x57 from Costa Rica, and only one x55 from Malaysia, and I would agree with the newer chips being better than the old ones.

are those batches by any chance 310XXX?

the ones in my bin are the very new ones from etaliers like egg and ncix.. not enough sample size to make a conclusive analysis, but i would say 311XXX aren't very good from what i am seeing.. or just bad luck on my part

i have a few more comming in and some that are still needing to be binned.. i'll post the results soon
just takes me to long to take off and reapply the eraser

I was pretty lucky with sb cpu on my last 2 purchases. On my 4th CPU, I got a almost 5.8ghz cpu, so I though I should buy another one for general use to slow down the degrading of this CPU. In the end, the new cpu I got do better. 5.9ghz is spi32m doable and I will try for 6ghz validation when I get my hands on some LN2

Ok just had a ran with this cpu on LN2. cold bugged after -30°c. SS and LN2 no difference. No 6 GHz.

The Egg has the 2700Ks in stock right now for 360.00 if anyone is interested.

(2) of 2700Ks...54X and 55X

Mostly building and using AMD systems I decided to try out Intel in the form of 2600K. I did not take the batch number on the CPU itself as I unfortunately already installed it by the time I realised I never wrote it down. Anyways, the batch number on the box states 3129B589 and the chip is from Costa Rica.
I went with a cheap motherboard to start with which unfortunately only has 4 phase VRM to the processor. The board is the Biostar TZ68A+ and I’m using 2 x 2GB Corsair Detonator GT 2133 running stock with stock timings of 9-10-9-24 T1. I’m using the True 120 Black for cooling and managed 4.7Ghz for everyday use with the core temps reaching 63C under Wprime1024 loads. I’m still getting to know the settings and the bios of this motherboard, but I was also able to bench at 5Ghz but the multi kept dropping to 49 – 48 under load with the temps going up to 67C max. Apparently the dropping of the multi under load could be as a result of the 4 phase VRM getting too hot, but I’m just stating what I read in some other forums. Ambient temperature in the room was 25C.

79 pages of posts, lots of gosip but no conclusion, also batch numbers mentioned in overclocking section (lots of posts).

Hey guys please tell me, with sandy bridge chips does batch really make "ANY" difference. I've gone through countless posts in the last few days to see if there is a trend in batch. What I've seen is a lot of L103 & 3103 are consistently clocking well, also L042. Do you guy's agree, partly agree or disagree. Just wanted to make sure as I know someone who believes that batch number in sandy bridge makes no difference at all.

Ok, I have an 3103 2500k coming my way soon, I think that it's not guaranteed that this chip will clock well but I have a better chance than buying in random.

Your help is greatly appreciated, thanks.

i'm wondering about that to but i guess there is no real conculsion yet. Maybe the answer for SB will be luck for a big part when you have batck xxx and xxx.

Hi. What voltage is your i7 2600k needing for stable 4.7GHZ?

i've binned 10 chips the past few weeks and have had 16 overall...
i personally don't think batch number matters at all.. if you buy 3 chips of the same batch.. you might get a 56x and you might get one that only does 51 or so.

It's just luck.. of course.. there might be some batches that have higher multi in average

Hi. What voltage is your i7 2600k needing for stable 4.7GHZ?

Hi Kagula... I'm actually at 4.8Ghz with 1.32Vcore under load. The vcome will hover around 1.36V when idling and drop to 1.32 under load. I tried 4.9Ghz now with 1.34Vcore under load and 1.4Vcore when idling and it seems to be problem free.

[flesheatinvirus]

My latest 2600K chip is in a base system at 4500mhz at 1.28vcore prime stable. It is a older batch L042B208.

[Ace.]

I have a 2700K and max. boot is 53
I Test 4.5 Ghz thats it for me I sell it

[aussie-revhead]

Guys have you found any gains with particular motherboards or do they have no affect on the cpu clocks? Do Z68's clock better or no difference?

[flesheatinvirus]

For Sandy chips the Asus Mive is about as good as it gets right now though I have not tested any Z68 boards. All the P67 series boards I have tested are very close. Its more the cpu with a strong IMC.

sup mate

i tested like 4 Z68 from giga and where worse than P67, still the best mobos i have is UD7 B2 and mi MIVE P67 B3

cheers
Sergio

[flesheatinvirus]

Sup andre. Those are both fantastic boards I agree, I still have a Gig UD5 B2 that is stellar despite there little mishap running sata 2 and 3 at the same time which I do not do so no problem. I like the looks of the new X79 UD7 but I would still rather have a MIVE and may grab one anyway.

[McDown]

Hey guys I'm going to buy a Maximus IV in the next couple of days and would like your opinion on which one to choose.
1. Rev.3 P67
2. Z68
As far as I understand both of them will support future IB update?

[humeyboy]

Wait on Z77 as it FULLY supports new CPU's inc native USB3 hopefully!

Not sure when Intel will make a proper non bastard chipset once again with no SATA 3Gbit/s and USB 2.0 on-board!

I regret upgrading back in September and wish I had not!

I would guess March 2012!

Using Gigabytes 'Quick Boost' feature in Touch BIOS only.. I'm not that familiar with overclocking so I figured I would start with this....

Is it any good?

Runs stable with OCCT and Burn test.


Batch# 3129B153

[flesheatinvirus]

Yes that looks promising. You may just have a keeper there. What cooling?

Hey man, have you by any chance tried a Gene-Z ? Can anyone offer an opinion on this? I was looking for a mobo that may oc better than my P67 EVO but maybe changing mobo wont help, right?

:-)

[flesheatinvirus]

Whats up aussie. I have not tried any Z types yet though the revision adds a few new things but most of the board is similar and performance should be close to P67. The EVO is a great board also but again the MIVE seems to be the best clocker from what I have seen.
